Programmed switch type temperature difference engine

Abstract

A programmed switch type temperature difference engine is composed of a special pneumatic motor, an ECU and a switch type heat exchanger in a combined mode, gas is used as working mediums, on the basis of the principle that gas expands at high temperature and shrinks at low temperature, temperature difference is converted into gas pressure difference of gas, and the gas pressure difference is converted into power to be output through the special pneumatic motor. Due to the fact that temperature difference exists anywhere and can be made and enhanced through technical means, the programmed switch type temperature difference engine can be widely applied to the fields of solar power generation, boiler waste heat recovery, recovery of heat energy of waste gas of engines and the like, and particularly when the programmed switch type temperature difference engine is applied to the solar power generation field, the solar energy utilization efficiency can be substantially improved, and the solar power generation cost can be substantially reduced. The programmed switch type temperature difference engine can achieve the purposes that new energy is used and the traditional energy utilization rate is improved, and makes contributions to energy conservation and emission reduction, development and utilization of green energy and construction of green industrial civilization capable of sustainable development.

Description

technical field [0001] The present invention relates to the technical field of engines. Background technique [0002] The Stirling engine is a well-known heat engine and a temperature difference engine, which has the advantages of high efficiency and low pollution. But the Stirling engine also has a big flaw. It adopts the design of heating cylinder and cooling cylinder. The cylinder itself is a heat exchanger. The limited surface area of ​​the cylinder limits its heat exchange capacity, so it is difficult to make a high-power engine. The maximum power of the machine is currently known to be less than 200Kw. In short, the defects of the Stirling engine itself limit its scope of use, and the research enthusiasm for the Stirling engine is extremely high, but there are few application cases. Contents of the invention [0003] The invention proposes a temperature difference engine, which also uses air as the working medium, uses the temperature difference between the two end...

But the Stirling engine also has a big flaw. It adopts the design of heating cylinder and cooling cylinder. The cylinder itself is a heat exchanger. The limited surface area of ​​the cylinder limits its heat exchange capacity, so it is difficult to make a high-power engine. Machine, currently known maximum power is less than 200Kw

In short, the defects of the Stirling engine itself limit its scope of use. The research enthusiasm for the Stirling engine is very high, but there are few application cases.
