What are the cleaning methods for the PE pad of car air conditioning core?

　　 Car air conditioning core PE pad It is an important device for exhaust energy recovery, high-temperature flue gas waste heat recovery, and computer CPU heat dissipation in large air conditioning systems. The structure has a vacuum filling head and a core body. The vacuum filling head is set on both sides of the vacuum filling channel. One side of the vacuum filling head is provided with a connecting pipe. The core body is composed of a vacuum filling channel and a plurality of plate-fin channels stacked at intervals. Diaphragms are provided above and below the vacuum supplementary liquid channel inside the car air conditioning core PE pad, and the two sides are sealed. Fins can be set in the channel. Baffles are provided at the upper and lower parts of the plate-fin channel, and sealing elements are provided on both sides. Fins are provided on the channel. Each plate-fin channel is divided into two parallel hot and cold medium channels by sealing elements. After assembly, they are arranged horizontally, obliquely, or vertically as a whole. During the use of the car air conditioning core PE pad, it needs to be cleaned frequently to ensure the use effect. So what are the cleaning methods for the car air conditioning core PE pad?

　　 Car air conditioning core PE pad Cleaning methods:

　　According to the overall structure of the car air conditioning core PE pad, sufficient space should be left at both ends of the core body to meet the requirements of in-situ (operating) cleaning and maintenance. When installing the fixed-tube car air conditioning core PE pad, sufficient space should be left at both ends to facilitate the removal and replacement of the pipes. In addition, when mechanically cleaning the pipes, brushing can be applied at both ends of the pipes. Sufficient space should be left at the fixed top cover end of the floating head heat exchanger to pull the tube bundle out of the shell, and a space of more than one meter must be left at the outer top cover end to facilitate the installation and removal of the outer top cover and floating head cover. Sufficient space should be left at the fixed top cover of the U-tube heat exchanger to pull out the tube bundle, or sufficient space should be left at the other end to remove the shell.

　　When using chemical cleaning for the car air conditioning internal core PE pad, the scaling quality should be analyzed and tested according to the actual operating conditions and different water qualities, and cleaning agents should be prepared separately.

　　Since the cleaning difficulty increases rapidly with the increase in the thickness of the oxide scale or deposits, the cleaning interval should not be too long. Regular inspection, maintenance, and cleaning should be carried out according to the characteristics of the production equipment, the nature of the heat exchange medium, the corrosion rate, and the operating cycle.

　　In addition, besides paying attention to regular cleaning Car air conditioning core PE pad In addition, waste heat recovery should also be paid attention to, so that energy saving can be achieved. For example, the waste heat recovery device of the car air conditioning core PE pad fully utilizes the high-efficiency heat transfer performance of the heat pipe. The high-temperature exhaust gas discharged passes heat through the heat absorption side of the heat exchanger, and the heat is quickly transferred to the heat release side of the heat exchanger through the heat pipe. Fresh air absorbs heat through the heat release side of the heat exchanger, and the heated fresh air is sucked into the oven through the negative pressure in the shaping machine oven to achieve energy saving.
