Application number is " 200820227643.X's " the patent of the water-cooling apparatus of current transformator power module " be used for ", solved the heat radiation of power model in the current transformer, the cooling problem, its (as shown in Figure 1) comprises the heat exchange air cooling equipment, water inlet and delivery port are fixed with respectively water dispenser 1,2 water pump 3, on it with the power model snap joint 4 of water inlet and delivery port, expansion tank 5, the heat exchange air cooling equipment comprises supporting box 6, supporting box 6 internal upper parts are fixed with cooling blower 7, being positioned at cooling blower 7 bottoms in the supporting box 6 is fixed with advancing, titting water outlet 8,9 radiator 10, be fixed with water dispenser 11 at supporting box 6, water dispenser 11 on the supporting box 6 links to each other with the admitting pipe joint 8 of radiator 10 through the first water-supply-pipe 12, water dispenser 11 on the supporting box 6 also is connected with the delivery port of each power model snap joint 4 through the second water-supply-pipe 13 simultaneously, the titting water outlet of radiator 10 links to each other with the water dispenser 1 at pump outlet place through the 3rd water-supply-pipe 14, and the water inlet of each power model snap joint 4 links to each other with the water dispenser 2 at pump outlet place through the 4th water-supply-pipe 22; Be connected with the 5th water-supply-pipe 15 between the water dispenser 1 of expansion tank 5 and pump intake, simultaneously expansion tank 5 be fixed in supporting box 6 on water dispenser 11 between be connected with pipeline 16; Water dispenser 1 at the pump intake place is fixed with water-filling valve 17; Be serially connected with another water dispenser 18 on the supporting box 6 that is fixed in the heat exchange air cooling equipment on the 3rd water-supply-pipe 14 between the titting water outlet 9 of radiator 10 and the water dispenser 1 at pump intake place; Radiator 10 comprises with described water-in and water-out pipe joint 8,9 cooling fluid water channel 19, is fixed with temperature sensor 20 in 19 sealings of cooling fluid water channel; Water dispenser 2 at the pump outlet place is fixed with pressure sensor 21.
During work, utilize the 17 pairs of cooling systems of water-filling valve on the water dispenser 1 of water pump 3 water inlets to fill water coolant, when expansion tank 5 liquid level positions reach requirement, finish the filling of cooling fluid.Cooling blower 7, water pump 3 are started working, and water pump 3 makes the water coolant circulation as the circulation power of water coolant.Water coolant from water pump 3 delivery ports out, through the water dispenser 2 at the pump outlet place water inlet to each power model snap joint 4, enter the water cavity of cooling base in the current transformator power module, the water coolant that the heat that semiconductor device produces in the current transformator power module is crossed by cooling base and circular flow is carried out exchange heat, high-temperature water cooling liquid after the exchange heat is from the delivery port of power model snap joint 4, through the second water-supply-pipe 13, the water dispenser 18 that is fixed on the heat exchange air cooling equipment supporting box enters in the interior radiator 10 of heat exchange air cooling equipment, 7 pairs of radiators of cooling blower 10 carry out air-cooled, the heat of water coolant by radiator 10 cooling fluid water channel 19 surfaces and on fin be released in the mode of thermal radiation and heat loss through convection, fully the water coolant after the cooling is through the titting water outlet of radiator 10, the water dispenser 1 of water pump 3 water inlets enters water pump 3, the water cooling to the power model of current transformer is finished in constantly circulation successively.Current transformer is in normal course of operation, and the volume of water coolant can vary with temperature and change, and simultaneously water coolant also has certain loss, utilizes expansion tank 5 to carry out the indication of liquid level and water coolant is replenished effectively.Water cooling system is in running, and bubble is very huge to the infringement of each parts, and expansion tank 5 and the pipeline 16 that is fixed between the water dispenser 11 on the supporting box 6 can effectively be got rid of it.Pressure sensor 21 is for detection of the direction of rotation of pressure and the water pump 3 of water coolant, and when the pressure of water coolant exceeded the direction of rotation mistake of the scope of system requirements or water pump 3, pressure sensor 21 output fault-signals were protected; Temperature sensor 20 is for detection of the temperature of water coolant, and when temperature exceeded the scope of system requirements, temperature sensor 20 output fault-signals were protected.
But, above-mentioned cooling device uses in the running in reality, cooling blower 7 cools off radiator 10 from the vent external air amount by the air channel, can flow into by frequent rain rainy day, temperature sensor 20 inside are by rain erosion, often cause temperature sensor 20 faults, the locomotive current transformer is not had protective effect; The simultaneously vibration of cooling blower 7 also causes temperature sensor 20 faults, has greatly shortened the useful life of temperature sensor 20, causes the protection of locomotive current transformer mistake.
Summary of the invention
The utility model provides a kind of composite cooling device for high-power converter for the problem that the water-cooling apparatus temperature sensor that solves for current transformator power module is easy to break down.
The utility model is to be achieved through the following technical solutions: the composite cooling device that is used for high-power converter, comprise that water inlet and delivery port are fixed with respectively the water pump of water dispenser, temperature sensor, described temperature sensor is fixed on the water dispenser at pump outlet place.
