A plate heat exchanger is a device that transfers a portion of the heat of a hot fluid to a cold fluid. It plays a leading role in the chemical, petroleum, power and food industries. It can be used as a heater, cooler, condenser, evaporator and reboiler in chemical production.
1.The heat supply temperature of the heat exchanger can not meet the requirements?
（1）The flow rate of the primary side medium is insufficient, resulting in a large temperature difference on the hot side and a small pressure drop.
（2）The cold side temperature is low and the cold and hot end temperatures are low.
（3）The flow distribution of multiple plate heat exchangers operating in parallel is uneven.
（4）The internal heat exchanger is heavily fouled.
2.The heat treatment of the plate heat exchanger can not meet the required temperature
(1)Increase the flow rate of the heat source or increase the diameter of the heat source medium line.
(2)Balance the flow of multiple plate heat exchangers operating in parallel.
(3)Disassemble the plate heat exchanger to clean the surface of the plate.
