A temperature control system is used for controlling a temperature of a control target. The system includes: a first circulation circuit through which a first heat transfer medium circulates; a second circulation circuit that is independent of the first circulation circuit and through which a second heat transfer medium circulates; and a third circulation circuit that is independent of the first circulation circuit and the second circulation circuit and through which a third heat transfer medium circulates. The third heat transfer medium has a usable temperature range wider than usable temperature ranges of the first heat transfer medium and the second heat transfer medium.

A cooling system includes a coolant source to cool down components of a processing chamber and a return line for the coolant coupled between the processing chamber and the coolant source. The return line has a valve, which includes a flow compartment having a first inlet and an outlet that support a default flow rate of the coolant, the flow compartment also having a second inlet. The valve has a plunger with a tip to variably open and close the second inlet to vary a flow rate of the coolant from the default flow rate. The valve has a shape memory alloy (SMA) spring positioned on the plunger between a side of the valve and the tip, the SMA spring attached to the tip to variably withdraw the tip from the second inlet in response to a rise in temperature of the coolant above a threshold temperature value.

A heat management apparatus comprises a first heat exchange portion, a second heat exchange portion and a throttle unit, wherein the first heat exchange portion is used for exchanging heat between a refrigerant throttled by the throttle unit, and a cooling liquid; and a first wall of the first heat exchange portion and a second wall of the second heat exchange portion are arranged opposite each other, such that the structure of the heat management apparatus is relatively compact.

A coolant circuit for a drive device. It includes a first coolant sub-circuit and a second coolant sub-circuit, in each of which a device to be temperature-controlled is arranged and which are fluidically connected to one another via at least one connecting valve, wherein at least one coolant pump is provided in each of the two coolant sub-circuits, which is designed in at least one of the coolant sub-circuits as a fluid pump having variable delivery direction. The disclosure furthermore relates to a method for operating a coolant circuit for a drive device.

A heat exchanger includes a body having an inlet header through which a fluid is introduced, and an outlet header through which the fluid is discharged; and one or more plates accommodated in the body and provided with flow path modules providing flow paths for the fluid introduced through the inlet header to flow to the outlet header. The heat exchanger further includes at least one flow path adjuster each having at least a portion thereof accommodated in the body and being movable or rotatable to open or close a part or all of the flow paths or to change directions of the flow paths so that a flow of the fluid is adjusted.

A control valve includes a casing, a valve body, seal tube members, a fuel passage, and a thermostat. The casing has an inflow port and a plurality of outflow ports. The valve body is rotatably disposed inside the casing, and valve holes are formed in a circumferential wall portion. The seal tube members communicate with the outflow ports, abut an outer circumferential surface of the circumferential wall portion, and are opened and closed by corresponding valve holes. Thermostat opens and closes the fuel passage in response to a detected temperature. A communication groove is formed on an inner circumferential surface of the casing. The communication groove causes the inflow port and an upstream portion of the fuel passage to communicate with each other by partially expanding a gap between the circumferential wall portion and the casing.
