SterlingEngine (restructure the Stirling engine to improve efficiency) The International procurement intelligenceStirling engine is a kind of thermal engine. Its working principle is to drive the piston movement through the thermal temperature difference and generate power. Compared with other traditional thermal engines, the Stirling engine has the advantages of small size, low noise and low pollution, but its efficiency is relatively low. Therefore, in order to improve the efficiency and performance of Stirling engines, reconstruction becomes particularly necessary. 1. Improvement of thermal efficiency The thermal efficiency of Stirling engine is an important indicator to measure its performance. The thermal efficiency can be improved by improving certain key parameters. ( 1) The greater the pressure ratio of the working substance than that of the Stirling engine, the higher the heat transfer efficiency, so the pressure ratio of the working material can be increased to improve the thermal efficiency of the Stirling engine. However, the greater the pressure ratio, the higher the manufacturing cost, and it is necessary to balance the pros and cons.(2) Optimizing the heat exchange structure of the engine. The heat exchanger structure of the Stirling engine directly affects its thermal efficiency. Optimizing the heat exchange structure of the engine can provide a more adequate thermodynamic cycle and then output more power. At the same time, increasing the surface area of the heat exchanger can also improve the thermal efficiency. Two. The power response of the Stirling engine is improved. The power response of the Stirling engine refers to its reaction speed and stability. In order to improve the power response of the Stirling engine, its internal structure needs to be improved. ( 1) Optimizing the piston assembly The piston assembly of the Stirling engine is the key to its power response. Optimizing its structure can improve the power response of the engine. For example, by reducing the volume of the top of the piston, the center of gravity will be lower, resulting in more stable rapid acceleration of the engine. ( 2) Optimizing the friction system is also one of the important factors that determine the performance of the Stirling engine.By optimizing the lubrication system and reducing the friction coefficient, the friction loss of the engine can be reduced and the power response can be improved. 3. Reducing the quality of the Sterling engine not only affects its power response, but also directly affects its power and fuel consumption. Therefore, reducing the quality of the Stirling engine is the key to improving its performance. ( 1) Reduce the volume of the engine. By reducing the volume of the engine, it can not only reduce its mass, but also improve the thermal efficiency of the Stirling engine, because smaller engines are often easier to reduce the loss of energy. ( 2) The use of lightweight materials and lightweight technology is a common way to reduce the quality of Stirling engines at present, such as using aluminum alloy to replace traditional heavy metal materials to greatly reduce the weight of the engine. In summary, while improving thermal efficiency, the new generation of Stirling engines should also pay attention to the reduction of power response and engine quality.This requires enhanced exploration and research in engine design, especially multidisciplinary intersections in the fields of thermodynamics and dynamics. I believe that with the continuous development of science and technology, the new generation of Sterling engines will become more and more popular in the market.
