What are the factors that affect the heat transfer coefficient of the gasketed plate heat exchanger
Author:
In the past ten years, the gasketed plate heat exchanger has become one of the most important equipment for heat exchange stations in central heating projects. With the rapid rise of sealed plate heat exchangers, the gap in manufacturing is getting smaller and smaller. Today, we will discuss the influencing factors of the heat transfer coefficient of sealed plate heat exchangers, so that everyone can have a deep understanding of heat exchangers.
The first influencing factor is the control of pressure drop. Central heating is a huge initial investment. The amount of energy used is many projects, and the energy loss in each link is a comprehensive operation and economic consideration. As the main equipment of the heat exchange station, the pressure loss of the gasketed plate heat exchanger should also be considered. The important point is the larger central heating system.
The second is the working parameters. The effect of gasketed plate heat exchanger on the heat transfer coefficient is very obvious. We can carry out the design and verification of the sealed plate heat exchanger. The working parameters will affect the heat transfer coefficient and the determination of the heat exchange area. In the air conditioning field, we often get a larger heat exchange area when we choose a sealed plate heat exchanger.
Finally, it is the corrugation angle of the gasketed plate heat exchanger. There are large angles and small angles, which refer to obtuse or acute angles. The pressure loss at different angles is different, and the flow rates on the primary side and the secondary side are different. We can configure the corrugated plates according to a certain ratio to obtain greater heat transfer efficiency and better save resources.
