Description

Motor housing heat dissipation structure

The present invention relates to a heat dissipation structure of a motor housing, and more particularly to a heat dissipation structure of a motor housing that takes away heat energy of a motor by flowing cooling water.

The motor is an indispensable machine for energy. The motor is driven by electric energy to convert electric energy into kinetic energy, which is generally used for exhaust fan or fan, or converted into electric energy by kinetic energy driving, generally used in generators; During operation, part of the energy will be lost in the form of heat, so that the motor temperature will rise with the working time, which will cause the motor's output characteristics to be bad or even damaged. To maintain the normal working conditions of the motor, the heat dissipation effect is not allowed. ignore.

The motor housing plays an important role in the heat dissipation system of the motor. As shown in FIG. 1, the conventional motor housing 10 includes a body 11, a front bracket 12 and a rear bracket 13, wherein the body 11 has fins on its surface. The sheet is used to increase the contact area between the body 11 and the air, and the heat is removed by the flow of the external air, thereby achieving a heat dissipation effect; but the motor has a higher output characteristic under a fixed size limit, and the temperature thereof also rises, the conventional The air cooling method does not effectively cool the motor.

Based on the above reasons, there is still room for improvement in the conventional motor housing. In view of this, the creator has actively studied and researched and developed years of experience in related product development. Constantly experimenting and improving, I finally developed this creation.

The main purpose of this creation is to provide a heat dissipation structure for the motor casing. The water cooling method is used to force the convection of the cooling water in the waterway to take away the heat energy of the motor, which can achieve the heat dissipation effect superior to the air cooling mode.

In order to achieve the above object, the present invention provides a motor housing heat dissipation structure including a body, a front bracket and a rear bracket; wherein the outer wall of the body includes a plurality of through holes as a water passage through which cooling water flows, the through hole a plurality of fins for increasing the contact area of the cooling water with the body, thereby increasing heat dissipation efficiency; the front bracket and the rear bracket are disposed on two sides of the body, and the front bracket and the rear bracket are respectively A plurality of first water channel grooves and a plurality of second water channel grooves are provided, so that the cooling water in the water channel can flow to the adjacent water channels to form a circulation flow path of the cooling water.

In order to further understand the features and technical contents of the present invention, please refer to the following detailed description and drawings of the present invention. However, the drawings are for reference and description only, and are not intended to limit the creation.
