Which types of heat exchangers have more use and heat exchange of plate heat exchangers
Dec 10, 2018

The heat exchanger, although only three words, contains a lot of knowledge, so it takes a comprehensive and in-depth understanding of the correct and reasonable use, in order to achieve the goal. Based on this specific requirement, the following will explain and explain the relevant knowledge of the heat exchanger, so that the product can be fully utilized in suitable occasions.


1. Does the choice of heat exchanger have to consider many aspects?

From a professional point of view, in the choice of heat exchangers, there are many aspects to consider, such as its working principle, what brand and its manufacturer, product quality and heat exchanger heat transfer efficiency, and product After-sales service, these aspects are taken into consideration in the future, in order to have accurate judgment and correct choice of results. Moreover, this is an important task that cannot be treated and carried out in order to avoid wrong choices.


2. Which types of heat exchangers are used more?

Among the heat exchangers, the more common and commonly used types are fixed plate type, floating head type and U-shaped tube type. Which one is selected is determined by the given process conditions, use requirements and use environment. . In these three heat exchangers, it should be known that the fixed plate type is suitable for occasions where the wall temperature of the pipe wall is not much different from the wall temperature of the casing, but the expansion joint is required, and the floating head type and the U-shaped pipe type are suitable for the pipe wall. In the case where the temperature differs greatly from the wall temperature of the shell, the two heat exchangers are more complicated in structure than the fixed plate.


3. What must be known on the heat exchanger?

Must be known on the heat exchanger, specifically:


(1) The important considerations in the heat exchanger are the heat exchange medium, inlet temperature, outlet temperature, specific use, installation and use environment, etc., which should be taken seriously and considered.

(2) The types of heat exchangers that are widely used are four types of plate heat exchangers, volumetric heat exchangers, shell and tube heat exchangers, and finned heat exchangers.

(3) In the selection and design calculation steps of the heat exchanger, it is necessary to fix the heat transfer area, and initially select the specific model of the heat exchanger, and use this to determine the flow path of the fluid in the heat exchanger.


4. Plate heat exchanger How does this heat exchanger heat exchange?

Plate heat exchanger is a heat exchanger which has a concave and convex sheet and it is pressed. The heat medium is on one layer, the cold medium is on the other layer, and the hot rolling mechanism is from the top to the bottom. The water flows out, and the cold medium flows from the bottom to the top, so that the heat exchange work of the heat exchanger can be performed, and the heat exchange effect is
