The mechanism of industrial cold water cold heat exchanger is introduced

 The process of industrial water is introduced and its heat transfer mechanism of cold heat exchanger analysis?

"Answer" is introduced and its mechanism of industrial cold water cold heat exchanger heat transfer analysis: we often say to the refrigeration and heat exchanger of industrial cold water machine, is mainly refers to the condenser and evaporator, they are two major pieces, of the four big refrigeration endothermic and exothermic capability and directly affects the system efficiency. Condenser and evaporator involves phase change heat transfer, this is a great characteristic of the two cooling heat exchanger. In addition, some in the refrigeration system and intercooler, supercooler, etc., the principle is similar to the general heat exchanger.

For water, cold water machine used in cooling towers, it is indispensable to large centralized refrigeration system water cooling equipment, although not a refrigeration and heat exchanger, but really involved in the heat, we will it is also summarized in this.

So, what is a heat transfer process? In the industrial mechanism of cold cold water system, entering the condenser in the high temperature and high pressure refrigerant vapor, by air or water in the surrounding environment condense into liquid; Enter the evaporator of the cryogenic liquid refrigerant from the surrounding air or cold agent in the absorption of heat load and gasification, so that the temperature drop of one area, achieve the goal of refrigeration. Refrigerants with the surrounding fluid through the process of transfer heat tube wall heat transfer process.

According to the form of a solid wall, the heat transfer process in the commonly used refrigeration equipment mainly has three kinds, namely, the heat transfer through plane wall in process, through the pipe of the heat transfer process and the heat transfer process through le wall.

1, the wall heat transfer: when the heat transfer surface for a tablet, or can approximate to a flat wall, heat from one side of the high temperature liquid through the wall to the other side of the cryogenic fluid, the heat transfer through plane wall was created.

2, circular tube heat transfer: in the condenser and evaporator of refrigeration system, heavy use of copper and steel of the pipe, so through the pipe of heat transfer is very common.

3, le wall: the heat transfer can be seen by the heat transfer equation, heat transfer per unit time increases with the increase of heat transfer coefficient and not only, but also increases along with the heat transfer surface. When the heat transfer coefficient up to a certain degree and difficult to improve, through increasing the denomination method increases the heat transfer, heat transfer is usually in the le or finned heat exchanger wall processing.
