DETAILED DESCRIPTION

(12) Embodiments illustrated herein relate to a vapor chiller configured cool vapors from fog machines. In particular, the vapor chiller is configured to store a cooled substance (such as ice). The chiller vessel includes a plurality of chambers. Each of the chambers in the plurality of chambers is configured to concentrate the cooled substance at a bottom of the chamber. The vapor chiller further comprises a fan coupled to the chiller vessel. The fan directs vapor through the chiller vessel across the cooled substance in the bottoms of the chambers.

(13) An example embodiment is illustrated in FIGS. 1 and 2. FIG. 1 illustrates a cross-section, side view of a vapor chiller 100 and FIG. 2 illustrates a top view of the vapor chiller 100. These views show the structure and internal components of the vapor chiller 100. The vapor chiller 100 includes a chiller vessel having side walls 102, back wall 103, front wall 132 and a bottom 104. In some embodiments, the side walls 102, back wall 103, front wall 132 and bottom 104 are constructed from rigid foam boards so as to provide insulation functionality.

(14) The vapor chiller vessel 101 includes a plurality of interconnected chambers 106-1, 106-2, and 106-3. While three chambers are shown in the example of FIG. 1, it should be appreciated that in other embodiments more or fewer chambers may be implemented. The chambers are formed by using baffles 108-1 and 108-2 between the chambers. The baffles 108-1 and 108-2 may be formed from rigid foam boards or other suitable materials. The baffles 108-1 and 108-2 are of a size, shape, and configuration to separate the chambers while still allowing vapor 110 to pass between the chambers 106-1, 106-2, and 106-3.

(15) Each of the chambers is configured in size and shape to concentrate a cooled substance 112 at the bottom of the chamber. In some embodiments, the cooled substance 112 may be ice. Alternatively, or additionally, the cooled substance may be dry ice, a mixture of water, ice, and salt (to facilitate cooling below the normal freezing temperature of water), or other cooled substances. In the example illustrated in FIG. 1, the chambers have angled walls 114 to facilitate concentration of the cooled substance 112 at the bottom of the chambers. In some embodiments, the walls 114 are formed of rigid foam boards or other suitable materials.

(16) In the example illustrated in FIG. 1, a fog machine 116 is coupled to the vapor chiller 100 through an inlet 118. The inlet 118 is an opening in one of the walls of the vapor chiller 100 that allows vapor 110 from the fog machine 116 to be input into the vapor chiller 100.

(17) The vapor chiller 100 further comprises a fan 120. For example, the fan 120 is configured to assist with forcing the vapor 110 through, and out of, the vapor chiller 100. In some embodiments, the fan 120 may be coupled to a controller configured to vary the speed of the fan. Varying the speed of the fan can be used to control how thick the vapor is that is output from the vapor chiller 100. Slower speeds can be used to output a thicker vapor, while faster speeds can be used to output a thinner vapor.

(18) With reference now to FIGS. 1, 2, and 3, the vapor chiller 100, in the example illustrated, further comprises a lid 122. The lid 122 is configured to cover the chambers 106-1, 106-2, and 106-3. In some embodiments, the lid 122 is constructed of a rigid foam board or other suitable material. This may be done to help insulate the vapor chiller 100. In some embodiments, the lid 122 may have a gasket 124 that helps to further insulate and seal the vapor chiller 100.

(19) The lid 122, in some embodiments, further comprises a baffle 126. The baffle 126 is configured in size and shape to extend into one or more of the chambers in a fashion that forces vapor towards the cooled substance 112.

(20) In some embodiments, the vapor chiller 100 includes one or more drains 128. The drains may be included to allow for draining the cooled substance 112 when in liquid form whether due to melting or otherwise.

(21) Other configurations may be implemented. For example, FIG. 4 illustrates a side, cross-section view of an example of a vapor chiller 400 having an internal fan 420 and piping 430 configured to route cooled vapor 410 within the vapor chiller 400 and out of the vapor chiller 400. In the example illustrated in FIG. 4, this can be performed to cause the vapor to be at lower height when exiting the vapor chiller 400.

(22) FIGS. 5, 6, 7, and 8 illustrate yet another example of an alternative vapor chiller 500 design. FIG. 5 illustrates a illustrates a cross-section, side view of a vapor chiller 500 and FIG. 6 illustrates a top view of the vapor chiller 500. These views show the structure and internal components of the vapor chiller 500. The vapor chiller 500 includes a chiller vessel 501 having side walls 502, back wall 503, front wall 530 and a bottom 504. In some embodiments, the side walls 502, back wall 503, and bottom 504 are constructed from rigid foam boards so as to provide insulation functionality.

(23) The vapor chiller vessel 501 includes a plurality of interconnected chambers 506-1, 506-2, and 506-3. While three chambers are shown in the example of FIG. 5, it should be appreciated that in other embodiments more or fewer chambers may be implemented. The chambers are formed by using baffles 508 and 526 between the chambers. The baffles 508 and 526 may be formed from rigid foam boards or other suitable materials. The baffles 508 and 526 are of a size, shape, and configuration to separate the chambers while still allowing vapor to pass between the chambers 506-1, 506-2, and 506-3.

(24) Each of the chambers 506-1, 506-2, and 506-3 is configured in size and shape to concentrate a cooled substance at the bottom of the chamber. In FIG. 5, the chambers 506-1, 506-2, and 506-3 have angled walls to facilitate concentration of the cooled substance at the bottom of the chambers 506-1, 506-2, and 506-3. In some embodiments, the walls are formed of rigid foam boards or other suitable materials.

(25) In the example illustrated in FIG. 5, a fog machine 516 is coupled to the vapor chiller 500 through an inlet 518. The inlet 518 is an opening in one of the walls of the vapor chiller 500 that allows vapor from the fog machine 516 to be input into the vapor chiller 500. In some embodiments, the inlet 518 may be formed, at least partially, from a PVC T-connector. This allows fog to be distributed laterally from the center of the inlet 518. Note that other embodiments may also use a PVC T-connector or other configuration configured to distribute vapor in a desired fashion. In some embodiments, the inlet 518 may be configured to distribute, such as by having holes or other openings laterally along the inlet, vapor along the inlet 518 rather than just at an end or ends of the inlet 518.

(26) The vapor chiller 500 further comprises a fan 520 between a vapor chamber 506-4 and the chamber 506-3. The vapor chamber 506-4 is formed by including an internal wall structure 533. The fan 520 is configured to assist with forcing the vapor through, and out of, the vapor chiller 500, through a vent 530 in the front wall 532. In some embodiments, the fan 520 may be coupled to a controller configured to vary the speed of the fan. Varying the speed of the fan can be used to control how thick the vapor is that is output from the vapor chiller 500. Slower speeds can be used to output a thicker vapor, while faster speeds can be used to output a thinner vapor.

(27) With reference now to FIGS. 5 and 7, the vapor chiller 500, in the example illustrated, further comprises a lid 522. The lid 522 is configured to cover the chambers 506-1, 506-2, 506-3, and 506-4. In some embodiments, the lid 522 is constructed of a rigid foam board or other suitable material. This may be done to help insulate the vapor chiller 500. In some embodiments, the lid 522 may have a gasket that helps to further insulate and seal the vapor chiller 500.

(28) Note that while in previously illustrated embodiments, the lid 122 included a baffle 126, in the illustrated example, the baffle 526 is part of the vapor chiller vessel 501. The baffle 526 is configured in size and shape to force vapor towards the cooled substance. Note that in this example, the vapor chiller vessel 501 comprises a space 534 between the baffle 526 and the bottom 504. For example, the space may be 1 inch in height. Similarly, a space 536 may be implemented between the baffle 508 and the bottom of the lid 522. The space 536 may be 1 inch in height. Note that other dimensions may be used in other embodiments. The baffle 526 may be coupled to the sides 502 to cause the baffle 526 to be tight to the lid 522 when the lid 522 is installed on the vapor chiller vessel 501.

(29) The following discussion now refers to a number of methods and method acts that may be performed. Although the method acts may be discussed in a certain order or illustrated in a flow chart as occurring in a particular order, no particular ordering is required unless specifically stated, or required because an act is dependent on another act being completed prior to the act being performed.
