Abstract
The invention discloses a liquid cooling source with wide-temperature-range liquid supply. The liquid cooling source comprises a cooling system, a cooling liquid circulating system exchanging heat with the cooling system and an electrical control system. The cooling system comprises a compressor, a condenser, a throttle device and an evaporator which are connected sequentially in a circulated manner. The liquid outlet of the condenser is connected to the liquid inlet of the compressor through an electrical regulating valve and a throttle valve. A pipeline connecting the air outlet of the compressor and the air inlet of the condenser is provided with a temperature sensor. The temperature sensor and the electrical regulating valve are connected with the electrical control system respectively. According to the liquid cooling source, an automatic sensing control manner is adopted, control manner is simple, and maintenance and monitoring are convenient; gas-and-liquid refrigerant after the condenser condenses and temperature drops is mixed with high-temperature gaseous refrigerant evaporated through the evaporator to allow the temperature in the compressor to drop, so that the problem of overload of a motor of the compressor is avoided, and service life of the machine unit is prolonged.
Description
Technical field
The present invention relates to art of refrigeration units, specifically a kind of wide temperature feed flow liquid cooling source.
Background technology
Be accompanied by Highgrade integration and the scale of electronic device, the heat-producing devices such as laser, radar also have a more and more stricter requirement to cooling, must adopt special liquid cooling source to provide the cooling fluid guarantee its normal operation.
Different electronic equipments has different requirements to the feed flow temperature range in liquid cooling source, simultaneously, even if same electronic equipment also has different requirements to the confession liquid temp under different working conditions.For guaranteeing the normal operation of these electronic equipments, just necessarily require the liquid cooling source must there is the self-adjustable ability in a big way to it for liquid temp; In the low situation of feed flow temperature requirement, adopt conventional compressor refrigeration system to work, if and in the higher situation of feed flow temperature requirement (more than 25 ℃), conventional compressor refrigeration system is in service there will be the problem that evaporating temperature is too high and suction temperature is too high, the too high meeting of evaporating temperature causes the overload of compressor electric motor, suction temperature is too high can cause exceeding standard of compressor exhaust temperature, and under these two kinds of operating modes, long time running all can cause the shortening in refrigeration compressor life-span.
Summary of the invention
