Description
Technical field
The present invention relates to a kind of hermetic circulating type pure water cooling system of device for high-power power electronic.
Background technology
Present device for high-power power electronic cooling circulating water system normally adopts the closed circulatory system to add the air cooling way of radiator heat-dissipation.Particularly, be to give aerial cooler with the heat delivered that recirculated water brings out, peripheral hardware blower fan air blast simultaneously looses 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, it is fixed that the peak temperature point that occurs with the locality basically comes.In fact each local temperature difference is very big, and this mode can only be applied to the little environment of difference variation.If at the quite big environment of temperature range, near the area of some for example under the line lacks of water arids, its day and night temperature scope is 5～45 ℃, depends merely on air-cooled cooling circulating water like this and just seems unable to do what one wishes.In addition then, because having a narrow range of temperature of aerial cooler makes sink-efficiency lower, therefore in the workplace, usually can see very huge aerial cooler crowd, because numerous aerial coolers, the loine pressure proportioning becomes the technical barrier of puzzlement.On the other hand, water-cooling system all is the device of no cold-storage, and system's thermal capacitance is little, and is big for the sensitiveness of weather, and when the system appearance temperature raises too fastly, the trip time of reporting to the police is short can to produce the tripping operation accident.
General water-cooling system design temperature is the design that adopts like Fig. 1: according to the environmental limit temperature and the cooling object temperature design temperature difference, according to limiting temperature t
2The situation of gas day by day that occurs, cooling object temperature t
3, suppose that the original heat sink design temperature difference is Δ t
1, the design environment limiting temperature is t
2, Δ t then
1=t
3-t
2In fact, high-power the time, adopt the environmental limit temperature to need a large amount of aerial coolers, not only land occupation but also defectives 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 t
1, then designing the temperature difference is Δ t
2=t
3-t
1＞Δ t

2Be Δ t
12 times, can save near half the aerial cooler.And design temperature is lower than the temperature difference of environmental limit temperature between this, owing to be not very long in each year, can adopt heat pump or refrigeration to solve when temperature is low through evening.
