The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of cycle cooling system of device for high-power power electronic, with realize various high power devices fast, high efficiency and heat radiation, and reduce volume, the weight of high power device and make use cost.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of cycle cooling system of device for high-power power electronic, comprise the liquid receiver that is communicated with successively by circulation line, be arranged on coolant recirculation pump, cooling piece and radiator on the described circulation line, the inlet of described circulation line and liquid outlet all are communicated to described liquid receiver, and described cooling piece is built-in to be arranged in the described device for high-power power electronic; Also comprise the radiator fan that corresponding described radiator arranges.
Preferably, also be provided with for the temperature detect switch (TDS) of controlling described radiator fan start and stop.
Pass through technique scheme, the cycle cooling system of a kind of device for high-power power electronic that the utility model provides, it is by cancelling radiating elements such as former device for high-power power electronic used section bar entity radiator and blower fan, cooling pieces such as built-in cooling water pipe or coldplate on device for high-power power electronic such as transformer and reactor, and by circulation line with liquid receiver, circulating pump, cooling piece and gilled radiator are communicated with, cooling fluid is circulated under the driving of circulating pump, thereby the heat efficient absorption with the device for high-power power electronic generation, and by gilled radiator heat is distributed fast, than with weight and volume all bigger entity radiating element be arranged on the practice on the high power device, the use of this cycle cooling system can effectively reduce volume and the cost of manufacture of high power device, and a cover cycle cooling system can be used for the heat radiation of many device for high-power power electronic simultaneously, and client's use cost effectively reduces.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below.
