Engine water return pipe assembly

Abstract

The invention belongs to the technical field of engine cooling and relates to an engine water return pipe assembly. The engine water return pipe assembly comprises two sets of water return pipe assembly main bodies which are parallelly arranged. Each set of water return pipe assembly main body comprises a plurality of insertion pipe assemblies which are in sealing connection in sequence. Each insertion pipe assembly comprises a water return pipe and a water return pipe insertion pipe which are equal in inner diameter. Each water return pipe insertion pipe is in sealing connection with the corresponding water return pipe. Each water return pipe is correspondingly connected with an air cylinder cover. The engine water return pipe assembly adopts an assembly structure; the mold opening number is effectively decreased; the manufacturing cost is reduced; and meanwhile, the liquid flow rate in the water return pipes is uniform, so that the flow resistance is small.

Description

technical field [0001] The invention belongs to the technical field of engine cooling, and relates to an engine return water pipe assembly. Background technique [0002] At present, in the return water pipe assembly of the existing V-type engine, the diameter is a variable-diameter return water pipe assembly whose diameter gradually decreases. Such return pipe assemblies have relatively fast flow rates, resulting in large flow resistance losses. The form of two-cylinder one-section return pipe assembly is mostly used. The shape of each section of the return water pipe is different, and each section of the return water pipe needs to be molded, and the cost is relatively high. Therefore, improvements in performance and cost of such return pipe assemblies are urgently needed. Contents of the invention [0003] In view of the above problems, the present invention provides an engine return pipe assembly. The return pipe assembly adopts an assembled structure, which effectivel...
