An evaporative cooling system for motor

Abstract

The invention belongs to the technical field of motor cooling, and particularly provides an evaporative cooling system for a motor. The invention aims to solve the problem that extra electric energy is consumed when an existing motor is cooled in a water cooling mode. The evaporative cooling system comprises an evaporative cooling part and a condensation part, the condensation part comprises a condenser, the evaporative cooling part comprises a first inlet, an internal channel and a first outlet which are formed in a shell and sequentially communicated, and the first inlet is located under thefirst outlet; a second inlet, a condensation cavity and a second outlet which are sequentially communicated are formed in the condenser; the first inlet is communicated with the second outlet, and the first outlet is communicated with the second inlet; and in the installed state, the condenser is located on the shell, so that the liquid first refrigerant in the condenser can flow into the shell under the action of gravity to absorb heat of the shell to become gaseous, the gaseous first refrigerant in the shell enters the condenser again under the action of buoyancy to release heat to become liquid, and energy waste is avoided.

Description

technical field [0001] The invention belongs to the technical field of motor cooling, and specifically provides an evaporative cooling system for a motor. Background technique [0002] There are mainly two types of casing cooling methods for existing motors. The first is air cooling, that is, a fan is installed at one end of the motor shaft, and the fan drives the airflow to contact the casing, so that the airflow takes away the heat of the motor. The second is water cooling, that is, a water circuit is set on the casing of the motor, and the cooling liquid is driven to circulate in the water circuit in the casing through a circulating pump, so that the cooling liquid can take away the heat on the motor. [0003] Compared with air cooling, water cooling can better cool the motor, so water cooling is used in many occasions. [0004] However, due to the long water path on the existing motor water-cooled casing, the temperature difference between the inlet and outlet cooling ...
