Heat exchanger, although only three words, but the product has a lot of related knowledge, so based on this point, the next step is to study the product, mainly to learn and master its relevant knowledge, so that we can have a correct understanding of the product and know how to use it reasonably, and then, we can achieve the purpose of use through correct and reasonable use.

1. Do you need to consider many aspects when purchasing heat exchanger online?

Online shopping of heat exchanger refers to purchasing heat exchanger products on relevant industry websites. There are some aspects that need to be considered because it is the job of product selection. Moreover, these aspects need to be considered are related to the purchase of the product, and they are all important considerations. Therefore, all of them need to be considered, and there should be no omission. Based on the above, we can know that the answer to this question is yes.

2. Is the plate in the plate heat exchanger important? How to maintain it?

From a professional point of view, the plate in plate heat exchanger is an important part of plate heat exchanger, and also an indispensable part. Therefore, based on this point, the answer to question 1 is yes. However, how to carry out maintenance is mainly disassembly and cleaning, and there are two cleaning methods: mechanical cleaning and online cleaning. The choice of cleaning method is determined by the actual situation and cleaning requirements.

3. Is there a corresponding formula for calculating the power of heat exchanger? Is there any difference between heat exchanger with phase change and without phase change in calculating heat load?

There is a corresponding formula for calculating the power of heat exchanger, which is q = f · K ·△ T, where f is the area of heat exchanger, K is the heat transfer coefficient, and △ t is the average temperature difference between the two sides of the fluid. However, there is a difference between the heat exchanger with phase change and without phase change when calculating the heat load, and it is necessary to know the specific difference so as to avoid mistakes.

4. Is the positive displacement heat exchanger a common type of heat exchanger?

At present, the positive displacement heat exchanger is a common type of heat exchanger, so it is certain that the answer to this question is yes. In addition, this kind of heat exchanger can store a large amount of water and has heat buffering capacity. However, its external volume is relatively large and the heat exchange efficiency is not very high. Therefore, it is necessary to decide whether to use this kind of heat exchanger according to the specific use environment and requirements.
