Waterproof and dustproof electric control box cooling structure

Abstract

The invention discloses a waterproof and dustproof electric control box cooling structure, which belongs to the technical field of automobile electric control. The waterproof and dustproof electric control box cooling structure comprises a box cover and a box bottom, wherein the box cover and the box bottom are matched; the box cover covers the box bottom; the surface where the box cover and the box bottom are matched is provided with a boss; the matching surface of the box bottom is provided with a sealing groove; the bottom part of the sealing groove is provided with a discharge port; the boss has an inverted trapezoidal section; a sealing ring is arranged between the top surface of the boss and the bottom surface of the sealing groove; the inner side of the sealing ring is provided with an exhaust groove; the top surface of the box bottom is provided with a groove; the groove and the lower matching surface of the box cover surround a cooling hole; and the cooling hole is communicated with the exhaust groove and the discharge port. Through arranging the cooling hole at the inner side of the box bottom, the outlet end of the cooling hole faces an inclined surface, heat is guided, hot air flow is exhausted more easily from the cooling hole and then exhausted outside the box body via the exhaust groove of the sealing ring and the discharge port, and better cooling effects are realized.

Description

technical field [0001] The invention belongs to the technical field of automobile electric control, and relates to an electric control box for a vehicle, in particular to a waterproof and dustproof electric control box heat dissipation structure. Background technique [0002] The existing automotive central control box only considers the sealing of the box or the heat dissipation of the product, but does not consider the sealing and heat dissipation of the product at the same time, because the sealing and heat dissipation are inverse. The airtightness of the ordinary electric control box is generally sealed by sealing the cover of the electric control box with a sealing rubber gasket, and secondly by filling the port of the electric control box with glue; the sealing effect of these two methods is relatively good, However, the production process is cumbersome, the product cost is high, and the heat dissipation performance is poor. There is an inverse relationship between ai...

Problems solved by technology

However, it is found in use that the heat dissipation effect is not ideal. On the one hand, the gap between the inner surface of the boss and the side wall of the sealing groove is a straight seam, and the hot air is not easy to discharge when it reaches the gap; on the other hand, the small part of the exhaust hole Blocked by the sealing ring, which prevents the hot air from exiting the exhaust hole
