Abstract
The invention provides an evaporation cooling cycle loop of an evaporation cooling electric motor. When stored cooling fluid reaches a certain height, a pressure controller sends out signals, an electromagnetic valve is opened; the stored cooling fluid flows into an evaporation cooling chamber through a bleeder tube and a holding valve; an inhaler contains water; an intake pipe connected with the holding valve is arranged on the position near the bottom of a box body and is immersed in the water; an air vent is arranged on the top part of the box body; the air entering the inhaler is filtrated and is discharged out from the air vent; the position near the bottom of the box body is provided with a bleeder tube and a valve to discharge the fluid. The invention has the advantage of zero leakage of cooling medium.
Description
Technical field
The present invention relates to a kind of circulation loop of vaporization cooling of evaporative cooling motor.
Background technology
The evaporation-cooled device of evaporative cooling motor is an airtight cooling medium circulation system, is in operation because air leaks into, and condensation space pressure is raise, and causes the coolant elevation of boiling point, reduces the evaporated cooling electric machine cooling effect.In order to keep rational operating temperature, must open the valve air-out, reduce the pressure of condensation space.Simultaneously, also to be discharged from this be unallowed to part coolant steam.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of circulation loop of vaporization cooling of evaporative cooling motor is provided.
Technical scheme of the present invention is: a kind of circulation loop of vaporization cooling of evaporative cooling motor, it is characterized in that: main condenser top condensation space leaks because of evaporating, cooling and circulating system, cause during entrained air that operating pressure raises, when pressure reaches the upper pressure limit of pressure controller setting, electromagnetically operated valve is opened, aspiration pump starts simultaneously, air and coolant gas mixture are gone into secondary condenser by the aspiration pump force feed in the main condenser, in secondary condenser, carry out heat exchange with cooling water, coolant is condensed into liquid and enters in the vapor-liquid separation case with air, air enters filter by unidirectional valve and enters atmosphere after filtering, quilt the pressure controller here detected and sends signal command after the cooling fluid of inflow vapor-liquid separation case reach a certain height, opens solenoid valve makes cooling fluid flow into the liquid storage part of evaporative cooling chamber, because the operation of aspiration pump reduces the pressure of main condenser, reach following the prescribing a time limit that pressure controller is set, electromagnetically operated valve and aspiration pump are closed simultaneously, finish exhaust cycle one time.
The present invention has the following advantages: the coolant zero leakage.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Embodiment: a kind of circulation loop of vaporization cooling of evaporative cooling motor, pressure controller 61 sent signal when the cooling fluid of storage reach a certain height, electromagnetically operated valve 63 is opened, the cooling fluid 44 that stores flows to evaporative cooling chamber 70 through discharging tube 47 and unidirectional valve 65, be filled with water 54 in the air cleaner 50, the air inlet pipe 53 that links to each other with unidirectional valve 45 is contained in the nearly bottom position of casing and is submerged in the water, exhaust outlet 51 is arranged at the top, the air that enters in the air cleaner is discharged by exhaust outlet after water filtration, nearly bottom is provided with discharging tube and valve 55, is used for drain.
