Plate heat exchanger is a kind of high-efficiency heat exchanger made of a series of metal plates with a certain corrugated shape. With its unique working principle and unique composition structure, it stands out from many heat exchangers.Depending on the heat exchange requirements and operating conditions, the choice of heat exchangers will vary.The heat transfer principle of the plate heat exchanger is the heat transfer of the partition wall.The hot and cold fluids conduct heat through the plates, and the cold and hot fluids form convection to achieve better heat exchange effects.
The use environment of plate heat exchangers is relatively good, and the pressure requirements are low. At this time, thinner plates should be selected for processing.Thin plates save costs. It is important that the reduction of plate thickness greatly increases the heat transfer coefficient of the heat exchanger.
According to preliminary estimates, even if the plate thickness of the heat exchanger is reduced by 0.1mm, the heat exchange coefficient can be greatly increased, so that the heat exchanger has better heat exchange capacity.Therefore, when the use conditions are better, a thinner plate heat exchanger should be selected.
The use environment of plate heat exchangers is relatively good, and the pressure requirements are low. At this time, thinner plates should be selected for processing.When the use environment is poor, such as higher floors and no district heating scheme, the pressure on the heat exchanger may reach 1.6 MPa or even higher.In order to ensure the stable operation of the heat exchanger, you can choose to sacrifice part of the heat exchange capacity and use thicker plates for processing.Although the heat exchange effect is slightly reduced and the cost is increased, it can ensure the stable operation of the heating system and prevent plate deformation and leakage due to excessive pressure.
