换热器在石油、化工、医药、冶金、电力、动力、制冷、热泵、食品等行业中占有举足轻重的地位。随着我国工业的不断发展,对能源的利用、开发和节约的要求不断提高,工业上的节能节水成为企业发展大计的一个重要组成部分,因此对换热器的要求也日益加强。如何增强换热器的换热性能,提高传热系数是换热器改革的主要研究方向。在常规换热器内(如列管式、板式、波纹管式、螺旋板式等)换热壁两侧面积基本相等,这样就造成换热面积相等,但两侧热交换介质换热系数不同从而导致热交换不平衡,使总传热系数低,热交换效果不佳,造成能源的浪费。为了解决这一问题,一般企业所采用的办法是加大换热面积,但是这样又使得换热器的体积过于庞大,同时对于换热系数大的一侧来讲也是一种换热面积的浪费。针对气(汽)体和液体换热的
Heat exchanger in petroleum, chemical, pharmaceutical, metallurgy, electric power, power, refrigeration, heat pumps, food and other industries occupy a pivotal position. With the continuous development of our country’s industry, the requirements for the utilization, development and saving of energy are continuously increasing. Energy-saving and water-saving in industries have become an important part of the enterprise development plan. Therefore, the requirements for heat exchangers are also increasingly strengthened. How to enhance the heat exchanger performance, heat transfer coefficient to improve the heat exchanger is the main research direction. In conventional heat exchangers (such as tube type, plate type, corrugated pipe, spiral plate, etc.) on both sides of the heat transfer wall area is equal, thus resulting in equal heat exchange area, but both sides of the heat exchange medium heat transfer coefficient to different Resulting in unbalanced heat exchange, low total heat transfer coefficient, poor heat exchange effect and waste of energy. In order to solve this problem, the general business approach is to increase the heat exchange area, but this makes the volume of the heat exchanger is too large, while the heat transfer coefficient is also a large side of a heat exchange area waste . For gas (vapor) body and liquid heat transfer
