Description
Technical field
The present invention relates to a kind of enclosed composite cooling system.
Background technology
Present device for high-power power electronic cooling circulating water system, normally adopt the Closed Cycle system to add the air cooling way of radiator heat-dissipation.Particularly, be that the heat that recirculated water is brought out is transferred to aerial cooler, peripheral hardware blower fan air blast simultaneously falls apart heat walk with the wind.Yet circulating water temperature changes along with the variation of ambient temperature.On the one hand, the variation recirculated water along with ambient temperature also is periodically variable.From design temperature, the peak temperature point substantially occurred with locality comes fixed.In fact each local temperature difference is very large, and this mode can only be applied to the little environment of difference variation.If the quite large environment at temperature range, near the area of some the lack of water arids under the line for example, its day and night temperature scope is 5～45 ℃, depends merely on so air-cooled cooling circulating water and just seems unable to do what one wishes.Separately, because having a narrow range of temperature of aerial cooler makes sink-efficiency lower, therefore in workplace, usually can see very huge aerial cooler group, due to numerous aerial coolers, the loine pressure proportioning becomes the technical barrier of puzzlement.On the other hand, water-cooling system is all the device without cold-storage, and the system thermal capacitance is little, large for the sensitiveness of weather, and when system occurs that the temperature rising is too fast, the trip time of reporting to the police, short meeting produced trip accident.
The design of general water-cooling system design temperature: according to environmental limit temperature and cooling object temperature designed temperature difference, the situation of gas day by day occurred according to limiting temperature t2, cooling object temperature t3, suppose that the original heat sink design temperature difference is Δ t1, the design environment limiting temperature is t2, Δ t1=t3-t2.In fact, high-power the time, adopt the environmental limit temperature to need a large amount of aerial coolers, not only land occupation but also the defects such as fluid resistance, proportioning are arranged.From the thermal conduction study angle, single increase heat exchange area can provide more powerful heat-sinking capability really; If the raising temperature difference will reduce aerial cooler under equal-wattage.The design environment temperature is t1, and designed temperature difference is Δ t2=t3 – t1 > Δ t1.When Δ t2 is 2 times of Δ t1, can save nearly half aerial cooler.And design temperature lower than the environmental limit temperature temperature difference between this, owing to not being very long in each year, can when temperature is low, adopt heat pump or refrigeration to solve by evening.
