In a cooling apparatus of an electronic equipment that cools down a heating element by circulating a refrigerant, air taken in once is prevented from taking in again into a water tank. A main water tank 1 includes two side surface parts 1a and 1b, and a cylindrical tubed part 1c. An inflow opening 2 is attached to a center of the side surface part 1a, and an outflow opening 3 is attached to a center of the side surface part 1b. A flexible pipe 6, which is made by a flexible material, is attached to the outflow opening 3 and a weight 7 is attached to an end of the flexible pipe 6.

A temperature IC is mounted to a card mounted within an electronic apparatus for monitoring airflow rate around the card to provide an alarm signal. The temperature IC includes a first IC including a temperature sensor and a second IC disposed downstream of the first IC. The second IC includes a temperature sensor and a resistor as a heating element. The second IC includes a first arithmetic unit that forms the difference in temperature out of two inputs of the temperature sensors, and a second arithmetic unit that determines thermal resistance of the second IC out of the difference in temperature and the quantity of heat released from the resistor. A memory stores date indicative of a relation between values of airflow rate and values of thermal resistance. A third arithmetic unit is provided to refer the stored data using the determined thermal resistance to find airflow rate.

A cooling structure is provided for a multichip module on which integrated circuit devices (i.e., LSI devices) having heat-radiation surfaces are mounted, wherein there are provided a heat sink, thermal conduction blocks and thermal compounds. Recess portions are formed at a surface of the heat sink in connection with the integrated circuit devices of the multichip module. Low melting point metal material such as solder is supplied to interiors of the recess portions of the heat sink. The thermal conduction blocks are partially inserted into the interiors of the recess portions under the condition where the low melting point metal material is heated and melted, so that the thermal conduction blocks temporarily float in the melted material. To avoid heat transfer toward the integrated circuit devices, a heat insulating sheet is provided on the thermal conduction blocks. Then, the low melting point metal material is solidified, so the heat insulating sheet is removed. The thermal compounds are placed on the thermal conduction blocks. Thus, the integrated circuit devices and the thermal conduction blocks are connected together by means of the thermal compounds. Because of temporary floating of the thermal conduction blocks in the melted material, it is possible to absorb dispersion in heights and slopes of the heat-radiation surfaces of the integrated circuit devices.
摘要:
A cooling apparatus for integrated circuit chips in which the pressure of coolant does not affect the pressure exerted by the cooling apparatus on the chip. A block is provided with a plurality of holes, and cooling members are inserted in these holes. An elastic member is provided between the block and the cooling member, and the cooling member is supported in the block by the elastic member. Each of the cooling members are connected by pipes, and a bellows is provided in the pipe. When the block is loaded on the substrate on which the integrated circuit chips are mounted, the elastic member deforms and the cooling member is displaced in accordance with the height and inclination of the integrated circuit chip. The lower surface of the cooling member is brought into close contact with the integrated circuit chip due to the deformation of the elastic member. The bellows deforms in accordance with the displacement of the cooling member to ensure the normal connection of the pipe. When the coolant is supplied through a nozzle into the cooling member, the expanded bellows pushes the pipe up but does not push the cooling member down since the nozzle is fixedly secured in the cooling member.
