Description

TECHNICAL FIELD [0001] The present invention relates to an oil cooler for an electromagnetic field, and an electronic equipment cooling method using the oil cooler.

The present invention relates to an oil cooler for an electric field and a cooling method for an electronic equipment using the oil cooler. More particularly, the present invention relates to an oil cooler for an electromagnetic field, which efficiently cools oil by using a vaporizing portion of the cooling system and cools electronic equipment such as a CPU, , An electromagnetic oil cooler for circulating and cooling the heated oil through a vaporizer after cooling the electronic equipment, and an electronic equipment cooling method using the oil cooler.

In general, various heat sinks are attached to the surface of a heating element for cooling a heating element, and a heat pipe is used to cool the heating element by introducing air into the heat sink by using a cooling fan or the like and to increase heat transfer efficiency.

However, in the above-mentioned method, not only the efficiency of transferring the heat generated from the heat generating element to the cooler is lowered but also the temperature is affected by the ambient air temperature by blowing air to the fan when cooling the transferred heat, It is difficult to obtain.

For example, when the radiator system is cooled by air at 50 ° C, the inlet temperature and the discharge temperature of the cooling water are actually about 1 ° C or so. This is because when the air temperature rises, the cooling temperature also rises proportionally This is because the target cooling temperature can not be maintained.

In addition, the method of driving the heat sink by attaching the cooling fan to the heat sink poses a problem of low cooling efficiency as well as noise of the cooling fan.

In the case of the radiator system, since the surrounding air is directly introduced into the radiator by using the cooling fan and cooled, there is a limit of the cooling temperature, and not only the heat (cooling) loss generated in the heat transfer process is high, There is a problem that it is not effective in a device generating high heat.

In addition, in the case of the cooling method using the heat sink and the cooling fan, since the inside of the equipment must be opened, dust and various harmful substances accumulate in the equipment, and the functions such as waterproofing can not be expected at all.

In addition, deterioration of electronic components due to overheating of electronic components in the event of overload has resulted in problems such as shortening the service life of the product, increasing the frequency of occurrence of failures, and deteriorating performance.

In addition, the cooling system using the air circulation structure is relatively large in the overall volume of the product, and fluctuates in relation to the temperature of the atmosphere, so that the equipment can not be maintained at a constant temperature.

On the other hand, cooling oil, which is designed separately for cooling purpose such as viscosity and ignition point (166 ℃ or more), is liquid paraffin series and ester series nonconductive oil and has no influence on various electronic equipment, petrochemical materials and rubber.

In addition, a cooling system such as an air conditioner used in a vehicle as well as a general home is composed of a compression unit, a condenser, an expansion valve, and a vaporizer, and circulates the refrigerant.

The compression section converts the low temperature low pressure gas refrigerant into the high temperature high pressure gas refrigerant and the condensing section converts the gas refrigerant of high temperature and high pressure into the high temperature high pressure liquid. The expansion valve converts the high pressure liquid into the low temperature low pressure liquid, Temperature low-pressure liquid into a low-temperature and low-pressure gas, and the process is circulated to form a cooling system.
