(14) The present description includes one or more embodiments for a turbine fan and method of cooling, where compressed air is inserted into a vortex tube that cools said air, and upon leaving the vortex tube the cooled air spins an air turbine that has one or more fan blades attached. The spinning of the air turbine, and thus the one or more air blades, causes the blades to push said cooled air toward the desired object to be cooled. The one or more embodiments for turbine fan and cooling method include multiple elements for supplying the compressed air to the turbine fan. For example, in one or more embodiments, various motors, compressors, and air receiving tanks may be attached to the turbine fan. Elements included herein are meant to be illustrative, rather than restrictive. Persons having ordinary skill in the art relevant to the present disclosure may understand there to be equivalent elements that may be substituted with the present disclosure without changing the essential function or operation of the device.

(15) Turning to FIG. 1, FIG. 1 shows a section view of the FIG. 2 turbine cooling fan according to various aspects of the present disclosure. In one or more embodiments, this turbine fan may include an air compressor 1 that supplies compressed air through heat exchangers 15 to the vortex tube 2. In one embodiment, the turbine fan does not have heat exchangers, and air is supplied directly from the air compressor 1 to the vortex tube.

(16) FIG. 2 shows a front view of the turbine fan. In one embodiment, this view shows the vortex tube 2 outlet located next to the air turbine 3. In this embodiment, after the air goes from the compressor 1, through the heat exchangers 15, through the vortex tube 2, the air spins the air turbine 3. In one embodiment, the air turbine 3 is fitted with vanes to allow said air turbine 3 to revolve by the fast-moving air as it exits the vortex tube 2. In another embodiment, said air turbine is fitted with flaps or any other means that allows the air turbine to capture, and be pushed by, the exiting air from the vortex tube 2, creating the spinning motion.

(17) The air turbine 3, as shown in FIG. 2, is located inside of a panel. In order to allow the air turbine 3 to spin, bearings are used to allow the air turbine 3 to be connected to the panel while maintaining the capability to spin from the air flowing from the vortex tube 2. These bearing can include sleeve bearings, rifle bearings, ball bearings, fluid bearings, magnetic bearings, or any other bearing type that allows the air turbine 3 to spin while still be connected to the fan. In another embodiment, the air turbine does not use, bearings, but utilizes any other method commonly used by turbines to accomplish the task of being able to spin the air turbine while attached to a stationary object.

(18) In the FIG. 2 embodiment, the fan blades are attached to the air turbine 3. In this embodiment, as the air exiting the vortex tube 2 spins the air turbine 3, the spinning blades 10 attached to said air turbine 3 spin, and said spinning fan blades 10 push the air spinning said air turbine 3, due to it being located next to the fan blades after spinning the air turbine. Since the air that spins the air turbine 3 is located next to the fan blades 10 after it spins said turbine 3, a good amount of that air is captured by the fan blades 10 and directed in a direction away from the fan. Additionally, air around the fan is likely to be captured by the fan blades 10 and directed away from the fan as well. This air will be pushed, and directed towards, the direction the fan is pointed.

(19) In the FIG. 2 embodiment that fan has 3 fan blades 10. In another embodiment, the fan has one fan blade, and in further embodiments, it has multiple fan blades.

(20) The compressor shown in FIG. 1 is used to supply compressed air to the vortex tube 2. In some embodiments, the compressor is a device that converts power into potential energy. In one embodiment, this is accomplished by forcing air into a storage tank to increase the pressure. In one embodiment, the turbine fan includes an air receiving tank, that allows the turbine fan to store compressed air. In this embodiment the turbine fan does not have to be turned on every time the fan is used, as it has a supply of compressed air. In a further embodiment, the turbine fan does not sore the compressed air, and the air compressor must constantly be making more compressed air during use.

(21) In one embodiment, the turbine fan further includes a motor. This motor can be gas powered or electric, and is used to power the compressor 1. Compressors that do not have a built-in source of energy require a motor to be powered. In one embodiment, the turbine fan has a electric motor and is required to be plugged into an electric outlet in order to power the motor.

(22) In a further embodiment, when the fan is being used in a setting that has access to compressed air, such as in a tool shop or factory, the turbine fan, does not need a motor or compressor. In this embodiment, the turbine fan can connect to the source of the compressed air, and attach directly to the heat exchangers. In this embodiment the air would flow through the heat exchangers to vortex tube. In even a further embodiment, the turbine fan does not have heat exchangers either, and the compressed air can connect directly into the vortex tube.

(23) The heat exchangers 15 are used to transfer heat out of the air after it exits the compressor. In one embodiment, these heat exchangers are used to remove the heat from the air after it is supplied from an external compressed air source, such as a factory compressed air tank. In one embodiment, the heat exchangers are common fan heat exchangers that are commonly used with fans.

(24) The vortex, tube, as show in FIGS. 1 and 2, is a mechanical device that separates the compressed air, into a hot and a cold stream, after it leaves the compressor 1 and heat exchanger. In another embodiment, the turbine fan does not have a compressor or heat exchanger, and the vortex tube is separating the air directly from an external compressed air source. In a further embodiment, the external compressed air is connected to a heat exchanger, and the air flows to the vortex tube, and the turbine does not have a compressor. After the compressed air is injected into the vortex tube, in one embodiment, it enters a swirl chamber and is accelerated to a high rate of rotation. In this embodiment, doe to the conical nozzle at the end of the tube, only the outer shell of the compressed gas is to escape at that end (the cold stream), and the remainder of the gas is forced to return in an inner vortex of reduced diameter with the outer vortex (the hot stream). In one embodiment of the turbine fan, only the cold stream is used to push the air turbine, and the hot stream is discarded out the back of the fan.

(25) Turning to FIG. 3, an isometric view of one embodiment of the turbine fan is shown. In this embodiment, an electric motor powers a compressor that pushes compressed air through the heat exchangers to remove heat from the compressed air, and into a vortex tube that separates the compressed air into a hot and a cold stream. In this embodiment, the hot stream is exhausted out of the back of the fan, behind the panel for prevent it from being blown by the fan blades 4, and the cold stream is used to spin the air turbine. The spinning air turbine also spins the connected fan blades 4. These spinning fan blades 4 push the cold air 5 that is exiting the cold stream outlet of the vortex tube, and spinning the air turbine, towards the desired object, or person that needs to be cooled. This embodiment of the cooling fan is advantageous over known fans as it allows for the blowing of cold air from the vortex tube. Further, this cold air does not introduce moisture, and can be used in factories where water can cause rust or ruin electronics. Further, this fan has the advantage that is can be used outside to cool, unlike traditional air conditioners that have to exhaust their hot air in a separate area than what is being cooled to be effective, and fans that cannot blow cold air.

(26) FIG. 4 is a top view of one embodiment of the turbine cooling fan according to various aspects of the present disclosure. In this embodiment, when vortex tube 2 exhaust the hot and the cold air streams (exhaust vents 6), they travel through noise suppressors 12. These noise suppressors can include a piece of cloth or cotton at the tip of the exhaust the air passes through, deflectors that deflect the sound waves, a wire screen, or any other means to make the exhausting air quieter. These noise suppressors are meant to make the fan quieter to improve the users experience when operating the fan, and serve to lower the hissing sound of the venting air out of the vortex tube, through both the cold stream and hot stream exhaust.

(27) FIG. 5 is a front view of one embodiment of the turbine cooling fan according to various aspects of the present disclosure. This embodiment shows the fan blades 10 and the air turbine 3 from a front view.

(28) FIG. 6 is a section view of the FIG. 5 turbine cooling fan according to various, aspects of the present disclosure. In this embodiment, the electric motor 8 is seen powering the compressor 7. Additionally, the bearing assembly 9 is shown with an attached booster motor 16. The booster motor 16 is an additional motor used to help spin the fan blades on larger embodiments, where the air pressure coming from the vortex tube is not enough to spin the air turbine 3. This can be a problem when the fan blades 10 are too heavy, and a booster motor 16 is required to help spin the blades. In one embodiment, booster motor 16 can be any motor commonly used to spin fan blades. In a further embodiment, the booster motor and the air pressure blowing the air turbine 3 work in conjunction to spin the fan blades 10.

(29) In the FIG. 6 embodiment, the air stream is capable of spinning the air turbine at least partially. This means that, when the fain blades 10 are too heavy to spin the air turbine by the cold stream alone, the air stream is at least capable of starting to spin the air turbine. This could include the slightest amount of movement when the vortex is exhausting cold air. In this embodiment, the booster motor 16 assist in spinning the fan blades 10 by spinning the air turbine.

(30) FIG. 7 is an isometric view of one embodiment of the turbine cooling fan according to various aspects of the present disclosure. In this embodiment, separation panel 11 is shown. In this embodiment, the separation panel 11 is used to separate the cold air that exits the vortex tube and spins the air turbine and fan blades 10, from that hot air stream that is exhausted from the vortex tube. In this embodiment, the hot vortex tube is embedded inside of the separation panel, and the hot air stream is vented out the back and the cold air is blown by the fan blades 10 towards the desired object or person to be cooled. In further embodiments, the vortex tube is not embedded into the separation panel, but the hot air is still exhausted behind the fan and the cold air is blown. The separation panel serves the purpose of preventing the hot air from mixing with the cold air and prevents the fan blades 10 from blowing the hot air.

(31) FIG. 8 is an isometric view of one embodiment of the turbine cooling fan inside of a cabinet according to various aspects of the present disclosure. This embodiment shows the turbine fan located inside of cabinet 14, and finger guard 13 on the front of said housing. The cabinet 14 is used to house the fan and serves the purpose of protecting the components of the fan from physical damage, make the fan more aesthetically pleasing, prevent physical injury to the user, allows the fan to be stackable, and allow for easier transportation. The finger guard 13 serves the purpose of protecting a user from getting their fingers cut by the spinning fan blades.
