  • Patent number: 8002025
    Abstract: A method includes circulating a heat transferring fluid in a substantially closed system including an interstice between a wafer and a chuck at a first pressure. The method further includes pumping the fluid out of the interstice and increasing the pressure of the fluid to a second pressure. The method further includes reducing the pressure of the fluid to the first pressure and returning the fluid to the interstice. In the system, the fluid in the interstice transfers heat from the wafer to the chuck, or vice versa, by conduction. The presence of a conducting fluid in the interstice thereby decreases the resistivity of the interface, and enables more efficient heat transfer from the wafer to the chuck.

    Abstract: A bypass valve for a heat exchanger including a plurality of parallel tubular members comprises a housing having a hollow plug portion adjacent to an actuator portion. The actuator comprises a reciprocating plunger extending into the plug portion and a solenoid having a central actuator shaft attached to the plunger, wherein the actuator shaft extends upon energization of the solenoid so that the plunger prevents bypass flow through the valve. The valve also comprises a temperature sensor for sensing a temperature of the fluid flowing through the heat exchanger, the temperature sensor being electrically coupled to the solenoid through one or more conductors, wherein the temperature sensor is located at the first end of the actuator shaft and the conductors extend through the hollow interior of the actuator shaft to the second end thereof.

  • Patent number: 6802368
    Abstract: A system for and method of controlling the temperature of a flat workpiece such as a semiconductor wafer are disclosed. The workpiece is mounted on a workpiece chuck which is mounted over a base between the chuck and a host machine such as a wafer prober used to test integrated circuits on a wafer. The chuck includes an upper portion on which the workpiece is mounted. The temperature of the upper portion of the chuck is controlled to control the temperature of the workpiece. The temperature of the base is controlled to reduce the amount of heat flow between the chuck and the host machine. A power and control system includes a switching power supply which provides power to system components including heaters in the chuck used to heat the workpiece. A series of filters removes electrical noise generated by the switching power supply such that low-noise operation is realized.

  • Publication number: 20040194949
    Abstract: There are provided a water-refrigerant heat exchanger 30 for exchanging heat between refrigerant discharged from a compressor 21 and engine-cooling water circulating an engine-cooling water circuit 10, prior to being fed into the radiator 22, and a bypass 25 for guiding the refrigerant prior to being fed into the evaporator 24 to the water-coolant heat exchanger 30 while bypassing the evaporator 24 and the compressor 21. When it is desired to accelerate the warming-up of the engine 11, the bypass 25 is closed to operate the compressor 21 to heat the engine-cooling water by high-pressure refrigerant, and when it is desired to complement the capacity of the radiator 12, the bypass 25 is open to guide the liquid-phase refrigerant to the water-refrigerant heat exchanger 30 to effectively cool the refrigerant by using the phase change of the refrigerant.

  • Publication number: 20030019620
    Abstract: Bypass valves and heat exchangers employing same are shown where the bypass valves cause the flow through the heat exchangers to be short-circuited under certain temperature conditions. The heat exchangers are formed of stacked plate pairs or tubes having enlarged communicating distal end portions forming inlet and outlet manifolds. The bypass valves can be plugged in where desired between the enlarged distal end portions to produce bypass flow between the inlet and outlet manifolds. The bypass valves include a housing which can be brazed in place during brazing of the heat exchanger. The housing has inlet and outlet openings in communication with the respective inlet and outlet manifolds for bypass flow therebetween. A removable temperature responsive actuator is located in the housing for blocking and unblocking the bypass flow through the valve.
