Embodiment Construction

[0011] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0012] refer to figure 2 , the cooling water jacket spoiler, which increases the solid-liquid heat exchange area and the turbulent flow intensity of the cooling liquid, makes the heat transfer between the cooling water jacket and the cooling liquid more sufficient and effective, including the V-shaped spoiler body 1, which is characterized by That is: the cross section of the V-shaped spoiler body 1 is V-shaped. The inner and outer contours of the cross section of the V-shaped spoiler body 1 are isosceles triangles with equal apex angles, and the apex angle varies from 27° to 32°, that is, the angle A is 27° to 32°. The ratio of the waist length of the isosceles triangle between the inner and outer contours of the cross section of the V-shaped spoiler body 1 is 0.45:1, that is, L1:L2=0.45:1. The V-shaped spoiler is arranged in the cooling water...

Abstract

The invention provides a V-shaped spoiler of a cooling water jacket of a synchronous reluctance motor for a vessel. The invention aims to solve the problems of low heat exchange efficiency and poor cooling effect of the cooling water jacket of the synchronous reluctance motor for the vessel in the prior art. The V-shaped spoiler comprises a V-shaped spoiler body, wherein the cross section of the V-shaped spoiler body is V-shaped; the inner contour and the outer contour of the cross section of the V-shaped spoiler body are isosceles triangles with the same vertex angles, and the vertex angles range from 27 degrees to 32 degrees. The ratio of the waist lengths of isosceles triangles of the inner contour and the outer contour of the cross section of the V-shaped spoiler body is 0.45: 1, and the V-shaped spoiler is arranged in the motor cooling water channel, so that the solid-liquid heat exchange area and the turbulence intensity of cooling liquid are increased, and the heat dissipation effect of the motor cooling water jacket is further enhanced.

Description

technical field [0001] The invention relates to a heat dissipation fitting for a motor, in particular to a V-shaped spoiler for a cooling water jacket of a synchronous reluctance motor for ships. Background technique [0002] As one of the core components of the ship, the synchronous reluctance motor, its excellent working performance is very important. Since the synchronous reluctance motor will generate a lot of heat during operation, it is necessary to select appropriate cooling accessories to control the temperature of the motor within a reasonable range to ensure the safe and stable navigation of the ship. As the size of the synchronous reluctance motor for ships tends to be miniaturized and the operation tends to be high-power, the conventional motor cooling water jacket has been difficult to meet the cooling demand. Therefore, it is necessary to design a cooling water jacket spoiler that can not only increase the solid-liquid heat exchange area, but also increase the...
