Heat exchanger, which is in the website products, but also one of the main keywords of the website, so it is necessary to learn and understand the product, mainly to learn and master its relevant knowledge, so that we can have learning objects and learning content, and then learn how to use the heat exchanger correctly and reasonably, so as to avoid the problem of wrong use.

1. For different types of heat exchangers, is the quotation of products important?

Heat exchanger, it can be said that there are many kinds of heat exchanger, and no matter which one to choose, it will involve the work of product quotation, and this work is an important work, which needs to be taken seriously and carried out, because it is related to the purchase of the product correctly. Therefore, based on this point, it can be concluded that the product quotation of different types of heat exchangers is an important work.

2. Is the inspection before and after use the same?

The heat exchanger should be inspected before and after use. Moreover, these two work are both important work, which can not be despised or treated carelessly, because the normal use of the product will be affected if it is treated lightly and carelessly. In terms of their work contents, these are two different inspection tasks, so they should not be confused to avoid affecting the smooth progress of the two work.

3. Is it important to distinguish heat exchanger without phase change from heat exchanger with phase change? Can the heat transfer coefficient of plate heat exchanger be improved by reducing the resistance?

It can be said that this work is very important to correctly distinguish the heat exchanger without phase change and heat exchanger with phase change, because it is related to the correct selection and normal use of the two heat exchangers, so as to avoid the wrong selection and adverse effects.

Plate heat exchanger, which is a specific type of heat exchanger, is also a common and common type in heat exchanger. Reducing the resistance of the heat exchanger can improve its heat transfer coefficient. Therefore, the answer to question 2 is yes. However, it should be noted that the resistance should not be reduced blindly, as it may bring some problems.
