There are several types of heat exchangers

There are three types of heat exchangers as follows:

A, thermal storage heat exchanger.

The regenerative heat exchanger has a valve switching function, rotary function. Thermal storage type heat transfer principle is through the solid composition of the heat storage body, the heat medium will first solid material heated to a certain temperature, it can be heated cold solids can be heat from the high temperature fluid to the low-temperature fluid, so as to achieve the purpose of heating.

Two, inter-wall.

Inter-wall heat exchanger classification is more: spray heat exchanger, jacketed heat exchanger, shell and tube heat exchanger, plate heat exchanger, immersed serpentine tube heat exchanger, I believe that we are generally more familiar with the tube as well as the plate, focusing on analyzing the principle of the work of these two types of heat transfer equipment.

1, plate heat exchanger: plate heat exchanger is the classic inter-wall heat exchanger, mainly composed of plates and sealant gasket, but also the big brother of all heat exchangers in the industrial field occupies a dominant position. Has the advantage of not to be underestimated, in many industries has gradually replaced the shell and tube type heat exchanger.

2, shell and tube (tube) heat exchanger: mainly to the heat exchanger principle to name, shell and tube heat exchanger will generally have heat transfer of two fluids. The flow outside the tube is called the shell process, the flow in the tube is called the tube process. The main structure is composed of tube sheet, shell, tube bundle, head and other parts, the shell is mainly circular. The shell is mainly circular, and the inner part is equipped with spiral tube or parallel tube bundle, and the two sections of the tube bundle are fixed on the tube plate.

Three, mixed.

Mixed heat exchanger classification and the principle of operation is based on direct contact between hot and cold fluids for heat transfer, to avoid the disadvantages of inter-wall side of the fouling thermal resistance, as long as you can ensure that the contact between the fluid is good to play a good rate of heat transfer, so the scope of application is also more extensive.

Heat exchanger, is a part of the heat fluid heat transfer to the cold fluid equipment, also known as heat exchanger. Heat exchanger is chemical, petroleum, power, food and many other industrial sectors of the general equipment, in the production of an important position.
