　　Car air conditioning core body PE padIt is an important equipment 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 liquid filling head and a core body, the vacuum liquid filling head is arranged on both sides of the vacuum liquid filling channel, one side of the vacuum liquid filling head is provided with a connecting pipe, and the core body is composed of a vacuum liquid filling channel and a plurality of plate fin channels stacked at intervals. Diaphragms are arranged above and below the vacuum supplementary liquid channel inside the PE pad of the automobile air-conditioning core body, and both sides are sealed, and fins can be arranged in the channel. The upper and lower parts of the plate fin channel are provided with partitions, both sides are provided with seals, and the channel is provided with fins. Each plate-fin channel is separated by a seal into two parallel hot medium channels and cold medium channels. After assembly, the whole is arranged horizontally, obliquely or vertically. In the car air conditioning core body PE pad needs to be cleaned frequently during use, so as to ensure the use effect. so what are the car air conditioning core body pe pad cleaning method?

　　Car air conditioning core body PE padThe cleaning method:

According to the overall structure of the PE pad of the automobile air conditioner core body, there should be enough space at both ends of the core body to meet the requirements of cleaning and maintenance under working conditions (operation). When installing the PE pad of the fixed tube automobile air conditioner core body, there should be enough space at both ends to pull out and replace the tube. In addition, when the pipe is mechanically cleaned, both ends of the pipe can be brushed. The fixed head end of the floating head heat exchanger should leave enough space to extract the tube bundle from the shell, and the end of the outer head cover must leave more than one meter of space to facilitate the installation and disassembly of the outer head cover and the floating head cover. The fixed top cover of the U-tube heat exchanger should leave enough space to withdraw the tube bundle, or leave enough space at the other end to remove the shell.

When using chemical cleaning of the internal core PE pad of the automobile air conditioner, the scaling quality should be analyzed and tested according to the actual use conditions and different water quality, and the cleaning agent should be prepared respectively.

Since the cleaning difficulty increases rapidly as the thickness or deposition of the oxide layer increases, 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, in addition to pay attention to regular cleaningCar air conditioning core body PE padIn addition, we should also pay attention to waste heat recovery, so as to achieve the purpose of energy saving. For example, the automobile air-conditioning core PE pad waste heat recovery device makes full use of the high-efficiency heat transfer performance of the heat pipe. The high-temperature exhaust gas discharged from the heat-absorbing side of the heat exchanger releases heat, and the heat is quickly transferred to the heat-releasing side of the heat exchanger through the heat pipe. The fresh air absorbs heat through the heat releasing side of the heat exchanger, and the heated fresh air is sucked into the oven through the negative pressure in the oven of the setting machine to achieve the purpose of energy saving.
