Engine cooling water circulating device

Abstract

The invention discloses an engine cooling water circulating device. The engine cooling water circulating device comprises a water pump, a warm-air water return pipe, a water inlet pipe and a water outlet pipe. The warm-air water return pipe communicates with the water pump. The water inlet pipe is arranged on the air inlet side of an engine cylinder body and connected with the warm-air water return pipe. The water outlet pipe is arranged on the exhaust side of the engine cylinder body and connected with an engine water outlet chamber through a flange plate. Both the water inlet pipe and the water outlet pipe are arranged in the length direction of the cylinder body, the structure is compact, and arrangement is orderly. Compared with the prior art, the water inlet pipe is additionally arranged, when cooling water is added into an engine, the cooling water enters the engine from the water inlet pipe and then returns to a water tank from the water outlet pipe, and thus the problem of unsmooth air exhausting of an engine cooling device can be solved easily; and in addition, the water outlet pipe is connected with the water outlet chamber formed at the water outlet end of the engine cylinder body through the flange plate, and thus the disadvantage that high-temperature resistance cannot be achieved through an existing rubber hose connecting method is avoided.

Description

technical field [0001] The invention relates to the field of engines, in particular to an engine cooling water circulation device. Background technique [0002] In order to reduce the working heat of the engine and reduce the fuel consumption, the working engine needs to be cooled. The existing cooling methods include water cooling and air cooling. Water cooling refers to transporting cooling water into the engine cylinder and outputting it to take away heat. The water outlet pipe, the water inlet pipe and the warm air return pipe of the existing engine cooling water circulation device are arranged in a complicated structure, and are disorderly, and require a large number of parts and components, which is not conducive to the light-weight production requirements. In addition, the existing water outlet pipe is connected with a traditional rubber hose when the water outlet chamber formed at the water outlet end of the cylinder is connected, and the rubber hose is easy to age i...

AI Technical Summary

Problems solved by technology

The layout of the outlet pipe, water inlet pipe and warm air return pipe of the existing engine cooling water circulation device is complex and messy, requiring a large number of parts, which is not conducive to lightweight production requirements

Moreover, the existing water outlet pipe is connected with the traditional rubber hose used when connecting the water outlet chamber formed at the water outlet end of the cylinder body. The rubber hose is easy to age in a high temperature environment, resulting in water leakage.
