New energy vehicle heat dissipation front end cover

Abstract

The invention discloses a new energy vehicle heat dissipation front end cover in the technical field of new energy vehicles. A supporting circle is welded on the outer side of the surface of a front cover plate; heat dissipation grooves are uniformly opened in the supporting circle; the center position on the surface of the front cover plate is provided with a motor shaft hole; heat dissipation holes are arranged on the surface of the front cover plate and located at the left side and the right side of the motor shaft hole; a small fan is arranged on the surface of the front cover plate and located at the top part of the motor shaft hole; a stainless steel mesh circle is welded on the inner wall of the supporting circle; and mounting angles are welded at the upper side, the lower side, theleft side and the right side of the supporting circle. As the heat dissipation grooves and the heat dissipation holes are arranged, the heat dissipation area can be increased and the heat dissipationeffects are improved; as the small fan, a small belt pulley, a belt and a large belt pulley are arranged, the large belt pulley can sleeve the outer wall of the motor shaft and rotates together withthe motor shaft, the small fan is thus driven to rotate, active heat dissipation is realized, heat dissipation effects are good, and the working efficiency and the service life of the motor are improved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a heat dissipation front cover of a new energy vehicle motor. Background technique [0002] New energy vehicles include hybrid vehicles, pure electric vehicles, etc. The motor is one of the main driving devices on the new energy vehicle. The motor will generate a lot of heat when it works for a long time, so the heat dissipation front cover of the motor needs to have a good heat dissipation effect. At present, the general motor heat dissipation front cover only has some heat dissipation holes, and the heat dissipation effect is average, which affects the working efficiency and service life of the motor. Therefore, we propose a new energy vehicle motor heat dissipation front cover. Contents of the invention [0003] The purpose of the present invention is to provide a new energy vehicle motor heat dissipation front cover to solve the problem that the current general ...
