[0002] An air conditioning unit refers to a device that processes air, called an air handling unit. A heat exchange coil is a heat pipe heat exchanger that uses a heat pipe as a heat transfer unit. It is a new type of high-efficiency heat exchanger, mainly composed of a shell, a heat pipe and a partition. The heat exchange coil can be used in air conditioning units to isolate air-conditioned areas with different water supply pressures, reduce the pressure of the cold water pipe, and achieve the purpose of reducing consumption.

[0003] The patent with the patent authorization announcement number CN205784780U discloses an antifreeze type heat exchange coil, in which the heat exchange coil and the header are installed on a fixing device, and the upper header is provided with at least one orifice, and the upper part of the heat exchange coil is connected to the upper header through the orifice, and the projection of the heat exchange coil on the plumb plane is a downwardly inclined water pipe. Although the above patent can improve the heat exchange efficiency by setting an inclined heat exchange coil, there are still deficiencies when the heat exchange coil is used in an air-conditioning unit. For example, when a damaged heat exchange coil needs to be replaced, the machine room space of the air-conditioning unit is limited, and the shape of the heat exchange coil is a fixed size, which easily makes it inconvenient to carry the heat exchange coil during the replacement process, thereby increasing the difficulty of replacing the heat exchange coil.
