Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, the utility model provides a motor evaporative cooling device comprises motor casing 1, sealed stock solution cavity 2, heat exchanger 3, radiator fan 4, evaporation steam pipe 5, backward flow liquid pipe 6, pressure regulating valve 7, liquid intercommunication pipeline 8, vapour intercommunication pipeline 9 and the interior cooling medium (the organic solvent of controllable boiling point) of sealed stock solution cavity.
The invention relates to a polyhedral motor with more than three surfaces, which is characterized in that an octahedral motor is taken as an example in the embodiment, eight sealed liquid storage cavities 2 are respectively and tightly fixed on eight surfaces of the octahedral motor by bolts, and are connected together by a liquid communication pipeline 8 below the sealed liquid storage cavities 2 to form a communication structure, a vapor communication pipeline 9 is connected together above the sealed liquid storage cavities 2, the vapor communication pipeline 9 is connected with the bottom of a heat exchanger 3 by an evaporation vapor pipe 5, and is connected with the bottom of the heat exchanger 3 by a reflux liquid pipe 6 to form a circulation loop; the specific working mode is as follows: the motor generates heat, the heat is through conduction mode to sealed stock solution cavity 2, the inside cooling medium of cavity is heated and is become the vapour attitude by liquid vaporization, because the motor constantly generates heat, the internal pressure of cavity increases, promote refrigerant steam and get into heat exchanger 3 through evaporating steam pipe 5, utilize radiator fan 4 to the cooling of refrigerant steam in the heat exchanger, make it condense into liquid, flow to the heat exchanger bottom through self gravity, the cooling medium relies on the action of gravity to flow back to sealed stock solution cavity 2 in through backflow liquid pipe 6, so the circulation repeatedly, play and continue refrigerated effect for the motor, consider for safety, avoid internal pressure too big, at heat exchanger top installation pressure regulating valve 7, through pressure regulating valve pressure release when pressure is greater than the default, ensure entire system internal pressure.
