Internal combustion engine cooling device

Abstract

The invention discloses an internal combustion engine cooling device. The internal combustion engine cooling device mainly comprises an outer frame, an upper water pipe, a lower water pipe, a fixed frame, a swing frame, a driving device and a reset frame. A turned-connection base is fixedly installed on the upper portion of the inner wall of the left side of the outer frame, a turned-connection sleeve is fixedly installed on the upper portion of the right side of the outer frame in a penetrating mode, and the upper water pipe is rotatably installed between the turned-connection base and the turned-connection sleeve. A rotary union with an annular groove is fixedly installed at the right end of the upper water pipe, the rotary union is in rotating contact with the interior of the turned-connection sleeve, a sealing ring is fixedly installed on the left portion of the inner side of the turned-connection sleeve, and the sealing ring is in rotating tight sliding connection with the rotaryunion through the annular groove in the rotary union. The structure design is reasonable, synchronous multipoint connection is driven by the driving device, synchronism and stability are good, througharrangement of an armored hose and the reset frame, the length of a cooling and heat dissipation path can be flexibly changed, different heat dissipation requirements are met, work efficiency is improved, a quick-release structure is adopted for quick-wear structures, and the quick-wear structures can be independently replaced, so that maintenance is facilitated.

Description

technical field [0001] The invention relates to a cooling device, in particular to a cooling device for an internal combustion engine. Background technique [0002] Internal combustion engine is a kind of power machinery, which is a heat engine that directly converts the heat energy released into power by burning fuel inside the machine. Internal combustion engines in a broad sense include not only reciprocating piston internal combustion engines, rotary piston engines and free piston engines Engine also comprises the gas turbine of rotary impeller type, jet engine etc., but usually said internal combustion engine refers to piston internal combustion engine, and reciprocating piston internal combustion engine is the most general. The piston-type internal combustion engine mixes fuel and air and burns it in its cylinder, and the heat energy released makes the cylinder generate high-temperature and high-pressure gas. The expansion of the gas pushes the piston to do work, and ...

Problems solved by technology

[0003] The cooling of existing large internal combustion engines generally adopts external air cooling, and the heat of the internal combustion engine is transported out of the body through the heat exchange medium, and the temperature is cooled by a special cooling device. However, the structure of the existing cooling device is fixed, and it is overloaded When the temperature is too high, it is impossible to carry out overload cooling, so that the overload work of the internal combustion engine will greatly damage the service life due to the high temperature, and the structure of the cooling device itself is unreasonable, which also results in a long time for its own maintenance and repair, and it is inconvenient to replace the vulnerable parts, resulting in the overall The problem of inefficiency
