Three kinds of heat exchanger of heat exchanger

In the mechanical equipment industry, the heat exchanger is an irreplaceable important member, both in the petroleum and chemical industry, has played a unique role. Therefore in the heat exchanger in the choice, we should fully consider the heat type heat exchanger, in order to meet the production needs of the company, this can not only reduce the cost of enterprises, but also improve the production efficiency of enterprise, create value for the company's economic development from two aspects.
Heat type heat exchanger is mainly divided into three categories: direct contact, regenerative and recuperative.
Direct contact
Also known as hybrid heat exchanger, refers to the two kinds of hot and cold fluid directly mixed heat transfer equipment. Under normal circumstances, one kind of fluid is gas, the other is liquid, but the lower the pressure of the liquid. In this case, the two fluids are easy to separate after heat transfer. Suitable for water cooling tower or spray condenser, etc..
The heat transfer equipment has certain limitation because it needs to mix two kinds of fluid and then have to be separated.
Regenerative type
The heat storage body which is made of solid is contacted with the cold and hot fluid respectively, so as to achieve the purpose of heat transfer. Heat storage body and thermal fluid contact a certain time, the accumulation of a certain quantity of heat, heat fluid left after the contact with the cold fluid, the heat transfer to the cold fluid, heat transfer. The heat exchange efficiency of the regenerative heat exchanger is relatively low, which is generally used as a preheating device.
Recuperative
Also known as the surface of the heat exchanger, refers to two kinds of hot and cold fluid in the pipe (board) on both sides of the flow through the tube wall (plate heat exchanger). The heat transfer mode is convenient, the first need not change the heat before mixing and heat transfer after separation, from the time and process to save the production cost; second heat transfer efficiency, improve the company's production efficiency.
Recuperative heat exchanger is currently the most widely used heat exchanger.
Three heat transfer methods have their own use, therefore, the production process must choose their own, suitable for their own is the best.
