Water cooling motor

Abstract

The present invention discloses a water cooling motor. The water cooling motor comprises a motor body. The water cooling motor also comprises: a water cooling box, wherein the water cooling box comprises a shell body arranged on the bottom of the motor body and an impeller arranged on a motor shaft of the motor body, the impeller is arranged in the shell body, the top edge of the shell body is sealed and fixed with the bottom of the motor body, and the side wall of the shell body is provided with a water inlet and a water outlet; a cooling module, wherein the cooling module comprises a water inlet pipe fixedly connected and communicated with the water inlet and a water outlet pipe fixed and communicated with the water outlet, and the water inlet pipe and the water outlet pipe are communicated. The working process comprises the following steps: water flows into the water outlet pipe via the water outlet under the drive of the impeller; the water flows into the water inlet pipe; the water dissipates the absorbed heat to the air in the cooling module, wherein the cooling module comprises the water inlet pipe and the water outlet pipe; and the water returns into the water cooling box via the water inlet pipe, thus forming one cooling circulation. The water cooling motor realizes the function of circulating cooling and can keep the motor working in a low temperature environment.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a water-cooled motor. Background technique [0002] During the working process of electric vehicles, all the power output comes from the motor. During the long-term operation of the motor, the stator and rotor heat up and heat the internal air, resulting in a high-temperature transition of the entire motor, and the motor bearings are also long-term. The high temperature operation will easily lead to damage to the motor due to overheating, which seriously reduces the working efficiency of the motor. Especially when the electric vehicle works when the external temperature is still high, the temperature of the motor directly affects the safe driving of the electric vehicle. Contents of the invention [0003] The purpose of the present invention is to provide a water-cooled motor, which has the function of circulating temperature, and can keep the motor working in a low temperatur...
