Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner refrigeration, in particular to a wet film device. Background Art

[0002] IT devices in the data center are in an uninterrupted working state. During this process, a large amount of heat is generated. To ensure the safety and reliability of the continuous operation of the devices, a humidifying component needs to be added to the devices. Since the devices in the data center have high requirements for the temperature and humidity of the air, using a wet film component with low energy consumption, low noise and less pollution to humidify the devices is a good way to meet this requirement. However, generally, the space for installing the wet film component is very narrow, and during the operation of the device, the wet film component needs to be replaced regularly. For users, the installation and replacement of the wet film component are relatively troublesome. Moreover, during the use of the wet film component, there is often a situation of dripping water. If the water droplets splash onto the electrical components, safety accidents may occur, posing a safety hazard. Summary of the Utility Model

[0003] Based on the above problems, the purpose of the utility model is to provide a wet film device, which is mainly applicable to the air-cooled outdoor unit of a multi-connected system, enabling the wet film component to be installed in a relatively small space, and at the same time simplifying the installation and replacement steps of the wet film component.

[0004] The technical solution adopted by the utility model is a wet film device, including a heat exchanger cover plate, a water receiving tray, a wet film component, wet film side baffles, a wet film upper baffle, a wet film lower baffle, a water pipe, and fasteners, wherein:

[0005] The heat exchanger cover plate is fixedly installed at the front and rear ends of the heat exchanger. The heat exchanger is used for heat exchange with the outside world, and the heat exchanger cover plate is used to protect the heat exchanger header, preventing the heat exchanger header from being collided by the outside world, resulting in the rupture of the header and the leakage of refrigerant; the water receiving tray is fixedly installed at the bottom of the heat exchanger, used to catch the water overflowing from the wet film component and drain it. The water receiving tray is conventionally provided with a drain port;

[0006] The wet film upper baffle is fixedly installed at the upper part of the side of the heat exchanger, and forms an upper limit groove with the side of the heat exchanger. The wet film lower baffle is fixedly installed at the lower part of the side of the heat exchanger, and forms a lower limit groove with the side of the heat exchanger. The wet film component is arranged on both sides of the heat exchanger, and the upper and lower ends of the wet film component are respectively limited in the upper limit groove and the lower limit groove;

[0007] The wet film side baffle is installed on the side of the heat exchanger through fasteners, and forms a side limit groove with the side of the heat exchanger. The front and rear ends of the wet film component are respectively limited in the front and rear side limit grooves;

[0008] The upper baffle of the wet film, the lower baffle of the wet film, and the wet film side baffles at both front and rear ends jointly fix the wet film assembly to prevent the wet film assembly from falling off.

[0009] The water pipe is installed on the side of the front end of the heat exchanger and is connected to the wet film assembly to supply water to the wet film assembly; the wet film assembly is used for humidification.

[0010] The installation method of the present utility model is as follows: Before installing the wet film assembly, first pre-install the heat exchanger, the water receiving tray, the lower baffle of the wet film, the upper baffle of the wet film, and install one wet film side baffle; then push the wet film assembly along the upper limit groove and the lower limit groove; then install the other wet film side baffle, install the fastening member and lock it to fix the wet film assembly; install the water pipe and connect it to the wet film assembly, and finally install the heat exchanger cover plate.

[0011] When the wet film needs to be replaced, loosen the fastening member, remove one wet film side baffle, disconnect the water pipe from the wet film assembly, then pull out the old wet film assembly, and then push in the new wet film assembly.

[0012] Further, the upper baffle of the wet film includes an upper baffle fixing portion that is attached to and fixedly connected to the side of the heat exchanger, an upper baffle bending portion that is perpendicular to the side of the heat exchanger, and an upper baffle limiting portion that is parallel to the side of the heat exchanger and extends downward. The upper baffle bending portion and the upper baffle limiting portion jointly form an upper limit groove with the side of the heat exchanger.

[0013] Further, the lower baffle of the wet film includes a lower baffle fixing portion that is attached to and fixedly connected to the side of the heat exchanger, a lower baffle bending portion that is perpendicular to the side of the heat exchanger, and a lower baffle limiting portion that is parallel to the side of the heat exchanger and extends upward. The lower baffle bending portion and the lower baffle limiting portion jointly form a lower limit groove with the side of the heat exchanger.

[0014] Further, the wet film side baffle includes a side baffle fixing portion that is attached to and fixedly connected to the side of the heat exchanger, a side baffle bending portion that is perpendicular to the side of the heat exchanger, and a side baffle limiting portion that is parallel to the side of the heat exchanger. The side baffle bending portion and the side baffle limiting portion jointly form a side limit groove with the side of the heat exchanger.

[0015] Furthermore, a through hole is provided on the side baffle fixing portion, a threaded hole is provided on the side of the heat exchanger, and the fastening member is a butterfly hand-tightening screw. The butterfly hand-tightening screw passes through the through hole on the side baffle fixing portion and then is screwed into the threaded hole.

[0016] By using the butterfly hand-tightening screw, the wet film side baffle can be disassembled and fixedly installed more conveniently without the aid of other tools, which further simplifies the installation and replacement steps of the wet film assembly.

[0017] Further, a groove for temporarily placing the water pipe is also provided on the side of the heat exchanger cover plate.

[0018] In this way, when it is necessary to disassemble and replace the wet film module from the water inlet side of the wet film module, that is, the front end of the heat exchanger, after disconnecting the water pipe from the wet film module, the water pipe can be temporarily placed in the groove reserved on the side of the heat exchanger cover plate to avoid the water pipe interfering with the extraction of the wet film module.

[0019] The beneficial effects of the present utility model are as follows:

[0020] When there are many components inside the air-conditioning unit, adopting the solution of the present utility model can, in the case of a small installation space for the wet film module, not disassemble too many parts of the unit, simply install the wet film module smoothly, and the maintenance and replacement processes of the wet film module are also very simple.
