Efficient heat dissipation device for automobile vent pipe

Abstract

The invention provides an efficient heat dissipation device for an automobile vent pipe. The device comprises two insulation covers with the semi-annular cross sections; the two insulation covers arerotationally connected through a rotating shaft, a heat dissipation cover with the semi-annular cross section is arranged inside each insulation cover, the axis of the heat dissipation covers coincides with the axis of the insulation covers, heat dissipation pieces are arranged between the heat dissipation covers and the insulation covers, the insulation covers and the heat dissipation covers areconnected through the heat dissipation covers, a limiting groove is formed in the outer surface of a pipe body of the automobile vent pipe, a limiting edge matched with the limiting groove is arrangedon the inner surface of each heat dissipation cover, the two heat dissipation covers are matched to form a cavity for fixing the automobile vent pipe, when an automobile runs, air rapidly passes a cavity formed between the heat dissipation covers and the insulation covers, hot air on the automobile vent pipe can be dissipated more rapidly, and heat dissipation of the automobile vent pipe is moreefficient.

Description

technical field [0001] The invention relates to auto parts, in particular to a high-efficiency heat dissipation device for an exhaust pipe of an automobile. Background technique [0002] The automobile exhaust pipe is used to discharge automobile exhaust gas. Due to the high temperature of the exhaust gas, after the car has been driving for a long time, the automobile exhaust pipe will gradually become hot under the heating of the exhaust gas. If there is no corresponding cooling device to dissipate heat from the automobile exhaust pipe, the automobile The exhaust pipe will be easily damaged, and the high temperature of the heat dissipation will affect the use of nearby components. Contents of the invention [0003] The object of the present invention is to provide a high-efficiency heat dissipation device for an automobile exhaust pipe. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a high-efficiency heat di...
