Water cooling device used for electric vehicles

Abstract

The present invention discloses a water cooling device used for electric vehicles. The device comprises: a water cooling motor, wherein the water cooling motor comprises a motor body and a water cooling box arranged on the bottom of the motor body, the water cooling box is provided with an impeller arranged on a motor shaft of the motor body, and the water cooling box is also provided with a water inlet and a water outlet; a radiator arranged on the upper part of the water cooling motor via an outer frame, wherein the radiator comprises a cooling fan and a cooling water tank adjacent to the cooling fan, and the cooling water tank is provided with a water inlet end and a water outlet end. The water outlet is connected with the water inlet end, and the water outlet end is connected with the water inlet. The working process comprises the following steps: water with heat flows to the water inlet end via the water outlet under the drive of the impeller, and enters into the cooling water tank; the cooling fan cools the cooling water tank, that is, cools the water in the cooling water tank; the cooled water flows out of the water outlet end under the effect of gravity; the water returns to the water cooling box via the water inlet, forming one cooling circulation. The device realizes the function of circulating cooling and the device 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 cooling device for electric vehicles. 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 work 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 cooling device for an electric vehicle, which has the function of circulating temperat...
