Water cooling device and external combustion engine with same

Abstract

The invention discloses a water cooling device and an external combustion engine with the same. The water cooling device is used for cooling a cylinder and comprises a water cooling sleeve and a connecting suite, wherein the water cooling sleeve is sleeved at the periphery of the cylinder to form a cooling cavity between the water cooling sleeve and the outer wall of the cylinder, and the cooling cavity is filled with cooling liquid; the bottom of the water cooling sleeve is connected to the bottom of the cylinder and is provided with a piston through hole; the connecting suite comprises a gas channel, an outer connecting piece and an inner flange; the gas channel extends to the bottom end of the connecting suite from the top end of the connecting suite and is used for gas to enter and leave the cylinder; the outer connecting piece is formed by extending outwards from the middle part of the outer wall of the gas channel, is provided with a plurality of first inner screw holes, and is hermetically connected with the top end of the water cooling sleeve; the inner flange is formed by extending outwards from the bottom end of the gas channel and is fixedly connected with the top end of the cylinder wall of the cylinder; and a second inner screw hole is formed on the inner flange vertically opposite to an inner bolt hole. The water cooling device can be prevented from being deformed due to an overheated gasket, so that maintenance cost is reduced.

Description

technical field [0001] The invention relates to an engine and its water-cooling components, in particular to a water-cooling device and an external combustion engine with the water-cooling device. Background technique [0002] The external combustion engine is a closed cycle reciprocating piston heat engine with external combustion. Because it was invented by Stirling in Scotland in 1816, it is also called the Stirling engine, also known as the heat engine. The medium substance (usually high-pressure gas) that transfers energy in the external combustion engine is called working medium, and is filled with the working medium of certain volume in one, two, four or more closed cylinders. One end of the cylinder is a hot chamber and the other end is a cold chamber. The working medium is compressed in the low-temperature cold chamber, and then flows into the high-temperature hot chamber to be heated rapidly and expand to do work. The heat brought by the continuous combustion of ...
