The plate heat exchanger has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, easy installation and cleaning, wide application and long service life. Its basic principle of heat transfer is that heat is transferred from high temperature objects to low temperature objects.
The working principle of the plate heat exchanger mainly depends on the role played by the ripples on the plates of the plate heat exchanger. The speed of the fluid flowing along the narrow and curved channel changes continuously, which causes the fluid to arouse a strong end motion at a small flow rate. Therefore, the destruction of the fluid boundary layer is accelerated, the heat transfer process is strengthened and the heat transfer capacity is improved.
