Matters needing attention when selecting heat exchanger
There are many types of heat exchangers, and each type has a specific application range. In a certain occasion, a heat exchanger with good performance may change the heat transfer effect and performance greatly if it is changed to another occasion.
Therefore, it is very important to correctly select the type of heat exchanger according to the specific situation. There are many factors that need to be considered when selecting a heat exchanger, the main ones are:
1. Heat load and flow rate;
2. The nature of the fluid;
3. The range of temperature, pressure and allowable pressure drop;
4. Requirements for cleaning and maintenance;
4. Equipment structure, material, size, weight;
6. Price, use safety and longevity;
In the selection of heat exchangers, in addition to considering the above factors, the structural strength, material sources, processing conditions, tightness, safety and other aspects should also be considered. All of these are often mutually restricted and influencing each other, which can be solved through design optimization. In view of different process conditions and operating conditions, we sometimes use special types of heat exchangers or special heat exchange tubes to achieve the purpose of reducing costs. Therefore, the process conditions and mechanical design requirements should be considered comprehensively, and the appropriate heat exchanger type should be correctly selected to effectively reduce the energy consumption of the process.
