A cooling system for cooling a machine tool having a machine temperature. The cooling system comprises gas source, refrigeration circulation, fan, and controller. The gas source is configured for providing gas. The refrigeration circulation comprises heat exchanger, compressor, condenser, and expansion valve. The heat exchanger is in fluid communication with the gas source and configured to cool the gas down to target temperature and to provide the gas to the machine tool. The compressor has operation frequency. The fan is configured to cool the condenser and has a rotation speed. The controller is connected to the compressor and the fan. When a target temperature difference that is equal to the machine temperature minus the target temperature is smaller than threshold temperature difference, the controller keeps the operation frequency at minimum frequency and sets the rotation speed to be smaller than a maximum rotation speed.

A regeneration device for regenerating a coolant dispersion with phase change material includes: a redispersion unit for redispersing the coolant dispersion, the redispersion unit including a restrictor; and a recooling unit that enables freezing of a phase change material by dissipating heat stored in the coolant dispersion. The recooling unit is arranged so that dissipated heat is at least partially recuperated in order to heat up the coolant dispersion to an inlet temperature.

A machine tool comprises a structure in which at least one component (12) of this structure is thermally insulated from the external environment and in which this component (12) is sealed so as to prevent fluid communication between the inside (18) and the outside of the component (12) of the structure.

A liquid-cooling termination structure having temperature sensing function is disposed on a liquid-cooling system which is used for performing a heat dissipating operation to a heat source of equipment. The liquid-cooling termination structure includes a water cooling head and a temperature sensing unit. The water cooling head is formed with an adhering surface used for being adhered on the heat source. The temperature sensing unit includes a sensing terminal, and a signal transferring cable extended from the sensing terminal. The sensing terminal is combined with the water cooling head from the exterior of the water cooling head, and the signal transferring cable is connected to the equipment for obtaining the temperature of the heat source through the water cooling head.

A core support system includes a support structure. The support structure includes a frame and a support member having a saturatable engagement layer disposed over the frame. A method of machining a core material incudes applying a fluid to an engagement layer of a support structure and saturating the engagement layer with the fluid, disposing a core material on the engagement layer, causing the fluid to freeze to secure to the core material to the support structure, machining the core material, melting the frozen fluid to release the core material from the support structure, and removing the core material from the engagement layer.

Machining apparatus for machining a chilled workpiece include a support surface that supports the chilled workpiece during machining by a machining tool of the machining apparatus, and further include a cooling system operatively coupled to the support surface. The cooling system prevents a machining temperature of an adhesive coupled to the chilled workpiece from rising beyond a predetermined threshold temperature during machining of the chilled workpiece, such that the cooling system prevents curing of the adhesive during machining of the chilled workpiece. The cooling system includes a cooling fluid that radiantly cools the chilled workpiece via the support surface while the chilled workpiece is supported by the support surface, such that the cooling system maintains the machining temperature of the adhesive (and of the chilled workpiece) below an ambient temperature. Related methods include machining the chilled workpiece using such machining apparatus.

An auxiliary apparatus using a four-way electronic valve to achieve temperature rise and fall effect on a component of a machine tool, which includes: a four-way electronic valve having a front end inlet, a front end outlet, a rear end outlet and a rear end inlet; the four-way electronic valve electrically connected to a control source; an outflow channel having one end connected to the rear end outlet; a return fluid incoming channel having one end connected to the rear end inlet; and a pump arranged on any one of the two of the outflow channel and the return fluid incoming channel, and electrically connected to the control source in order to be controlled by the control source to drive the fluid inside the channel where the pump is arranged thereon to move.

A thermal system may comprise a reservoir, a first fluid flowpath, and a second fluid flowpath. The first fluid flowpath may start at the reservoir and return to the reservoir. The first fluid flowpath may comprise, in a direction of the fluid flow, a first side of a sub-cooler, a liquid pump, a first side of a pre-heater, and a first side of an evaporator. The second fluid flowpath may start at the reservoir and return to the reservoir. The second fluid flowpath may comprise, in a direction of a fluid flow, a pressure regulator, a vapor compressor, a first side of a condenser, and an expansion value.
