Series type air cylinder cover water channel structure

Abstract

The invention provides a series type air cylinder cover water channel structure which comprises multiple cylinder covers. The interior of each cylinder cover is provided with a water passage. The positions, used for supporting mold cores, at the two ends of each water passage are provided with series water gaps. The water passages of every two adjacent cylinder covers are communicated through the series water gaps in the corresponding two ends. Annular grooves are formed in the outer edges of the series water gaps. O-shaped rubber sealing rings are embedded in the annular grooves. When the cylinder covers are assembled together, a general series water return channel is formed. The series type air cylinder cover water channel structure has the following beneficial effects that the general water return channel is naturally formed through the water passages in the cylinder covers, the number of components is reduced, cost is saved, compactness is improved, and the installation and operation intensity is lowered. Through reasonable design, the water return channel arranged in the cylinder covers and cooling water sleeves of the cylinder covers are formed into a whole, extra occupation of the internal spaces of the cylinder covers is avoided, and the cooling effect of the cylinder covers cannot be affected.

Description

technical field [0001] The invention belongs to the technical field of water channel cooling for internal combustion engines, and in particular relates to a serial cylinder head water channel structure. Background technique [0002] On the water-cooled internal combustion engine, since the cylinder head is located at the end of the cooling part, the cooling water needs to finally collect through the cylinder head to the main return pipe and then flow back to the water pump. In the case of a single cylinder head, in the prior art, an independent return water pipe is generally designed outside the cylinder head to collect cooling water from each independent cylinder head. Since the water collecting pipeline is longitudinally arranged along the cylinder head, its length is equivalent to the total assembly length of the cylinder head, and requires additional space and size. Because the first thing to consider is the reasonable arrangement of the intake pipe and exhaust pipe out...

AI Technical Summary

Problems solved by technology

Because the first thing to consider is the reasonable arrangement of the intake pipe and exhaust pipe outside the cylinder head to ensure the performance of the internal combustion engine, so the available space for the outflow of the external return water pipe is very limited and tense, resulting in such an external independent The return pipe is not only difficult to install, but also takes up valuable space on the internal combustion engine, which increases the volume and weight, and also increases the cost of processing and manufacturing
