    摘要: A cooling system used with a printed circuit board has at least a solid circuit component thereon. The cooling system comprises a cooling header and cooling modules connected to the cooling header. Each of the cooling modules engage to each of the components. The cooling module has a heat transfer plate connected to one end of a bellows which is connected to the cooling header at the other end. A layer of thermally conductive compound, such as a layer of thermal grease, is interposed between the heat transfer plate and the corresponding circuit component. The thermally conductive layer is initially pressed with a pressure higher than a critical pressure, and thereafter, the pressure is reduced to a working pressure exerted on the circuit component provided by the resilient force of the bellows and the hydraulic pressure of the coolant. The critical pressure is predetermined experimentally or practically. As the result, the thermal contact resistance between the heat transfer plate and the circuit component is favorably reduced and stabilized.

    摘要: A cooling system comprising an airtight box which accommodates a cooling module and an electronic device which is cooled by the cooling module and has a door which is opened when attending to maintenance of parts within the airtight box, a dew condensation preventing unit for absorbing humidity within the airtight box and/or replacing air or gas within said airtight box when operated, a coolant supply unit for recirculating a coolant between the coolant supply unit and the cooling module, and a controller for operating the coolant supply unit and the dew condensation preventing unit in response to a first instruction signal which instructs a cooling operation, and for heating the electronic device in response to a second instruction signal which instructs the maintenance of the parts within the airtight box, where only one of the first and second instruction signals exists at one time. The controller includes a circuit part responsive to the second instruction signal for supplying an operating signal to the electronic device to operate the electronic device for a predetermined time, so that the electronic device rises to a predetermined temperature due to heat generated by the electronic device itself.
