Abstract

An LSI temperature controlling system has closed LSI cooling water circuit, and a refrigeration circuit including a motor-driven refrigerant compressor, a first heat exchanger for exchanging the heat of the LSI cooling water and the refrigerant and a second heat exchanger for exchanging the heats of the refrigerant and another fluid. The motor speed is controlled by an inverter the operation of which is controlled based on the temperature of the LSI cooling water measured by a temperature detector. A heater is used to suppress dew formation on LSI substrates.
