Description

Technical Field

[0001] The present application relates to the field of heat exchanger cleaning, and particularly to a heat exchanger cleaning device. Background Art

[0002] When an automotive air conditioner is used for a long time, when air flow passes through the heat exchanger, particulate matters carried thereby, such as dust, will adhere to the surface of the heat exchanger, which will affect the heat exchange efficiency of the heat exchanger. At the same time, since the working environment of the heat exchanger is relatively closed and humid, bacteria are likely to breed and generate peculiar smell, which will further lead to a great reduction in the quality of the air blown into the passenger compartment. Therefore, it is very necessary to clean the heat exchanger regularly.

[0003] Currently, a circular tube with a plurality of small holes is usually arranged on the top of the heat exchanger, and cleaning liquid can be sprayed out through the small holes to clean the surface of the heat exchanger. This structure has some defects. The entire water column structure determines that the water outlets are sequential, which will cause uneven pressure difference inside and outside the small holes; in addition, the atomization effect of the sprayed water column is also poor (that is, the spraying uniformity is poor), which all lead to poor cleaning effect of the cleaning device. Summary of the Utility Model

[0004] In view of this, the purpose of the present application is to provide a heat exchanger cleaning device to solve the problems that the existing heat exchanger cleaning device cannot discharge water simultaneously and the atomization effect of the sprayed water column is poor, resulting in poor cleaning effect.

[0036] According to the present utility model, there is provided a heat exchanger cleaning device, as Figures 1 to 4 shown. The heat exchanger 4 cleaning device in this embodiment includes a liquid inlet portion, a liquid storage portion, and a bracket 3. The liquid inlet portion can introduce the cleaning liquid into the liquid storage portion and spray it out through a nozzle 25. The liquid storage portion is fixedly assembled with the heat exchanger 4 through the bracket 3. Hereinafter, the specific structures of the above-mentioned respective parts of the heat exchanger cleaning device according to the present utility model will be described in detail.

[0037] In this embodiment, as Figures 1 to 2 shown, the liquid inlet portion includes a joint 10 and a hose 11 connected in sequence. The joint 10 is correspondingly connected to a water pump so as to be able to introduce the cleaning liquid into the liquid storage portion. Under the pressure of the water pump, the cleaning liquid can be directly sprayed out by the following nozzle 25 and form a spray state. Although not shown in the figure, the water pump can be connected to a container filled with the cleaning liquid so as to be able to extract the cleaning liquid.

[0038] Furthermore, in this embodiment, as Figure 1As shown in the figure, the liquid storage part includes two water chambers connected in sequence (i.e., the first sub-water chamber 20 and the second sub-water chamber 21), and their shapes and structures are the same, which is convenient for disassembly, installation, maintenance and replacement. Taking the first sub-water chamber 20 as an example, the first sub-water chamber 20 is formed into a columnar structure, and a first connecting part 22 and a second connecting part 23 protruding from the first sub-water chamber 20 are respectively arranged at both ends in the extending direction thereof. Both the first connecting part 22 and the second connecting part 23 are formed into tubular structures, an external thread is formed on the outer side wall of the first connecting part 22, and an internal thread is formed on the inner side wall of the second connecting part 23. In this way, the corresponding connection between the first sub-water chamber 20 and the second sub-water chamber 21 can be realized, that is, the second connecting part 23 of the first sub-water chamber 20 is correspondingly connected with the first connecting part 22 of the second sub-water chamber 21.

[0039] Furthermore, in this embodiment, as Figure 1 shown and Figure 3 described, the above-mentioned hose 11 is correspondingly connected with the first connecting part 22 of the first sub-water chamber 20 so as to introduce the cleaning liquid into the interiors of the first sub-water chamber 20 and the second sub-water chamber 21. A plug 27 is correspondingly connected to the second connecting part 23 of the second sub-water chamber 21 to prevent the cleaning liquid from overflowing. It should be noted that the number of water chambers in the liquid storage part is not fixed and can be determined comprehensively according to actual situations such as the specifications of the heat exchanger 4, etc.; when multiple water chambers are required, the multiple water chambers can be connected in sequence. Along the connection direction of the multiple water chambers (i.e., the extending direction of the liquid storage part), the above-mentioned hose 11 is correspondingly connected with the first connecting part 22 of the first water chamber, and the above-mentioned plug 27 is correspondingly connected with the second connecting part 23 of the last water chamber to achieve the above technical effects.

[0040] Even further, in this embodiment, each water chamber is detachably connected with a plurality of nozzles 25. Taking the first sub-water chamber 20 as an example. As Figure 3 shown, a plurality of protruding third connecting parts 24 (two in this embodiment) are formed on the outer side wall of the first sub-water chamber 20. The third connecting parts 24 are formed into tubular structures and internal threads are formed on the inner side walls of the third connecting parts 24; the nozzles 25 are correspondingly connected with the third connecting parts 24 one by one, and a sealing ring 26 is arranged between each nozzle 25 and the corresponding third connecting part 24 to prevent the cleaning liquid from overflowing. It should be noted that the nozzles 25 in this embodiment can adopt existing atomizing nozzles, which can realize the screw connection with the third connecting parts 24 and can realize the atomization of the cleaning liquid. In addition, the connection manner between the nozzle 25 and the water chamber is not fixed. For example, they can also adopt a detachable connection manner such as pin connection, as long as the stability and sealing performance of the connection between the nozzle 25 and the water chamber can be ensured and the maintenance and replacement of the nozzle 25 are convenient.

[0041] In this embodiment, after the water chamber is stably connected to the nozzle 25, the water chamber is then correspondingly clamped to the bracket 3 to achieve connection with the heat exchanger 4. That is, each water chamber is provided with a hook, and the bracket 3 is formed with a clamping groove corresponding to the hook. It should be noted that clamping is a common component connection method in the art, so the specific structures of the hook and the clamping groove will not be described in detail. In addition, as Figure 1 shown, the bracket 3 in this embodiment is formed into a frame structure similar to a triangular prism, and it is formed with a plurality of through holes corresponding to the above-mentioned third connection portion 24; when the water chamber is correspondingly clamped to the bracket 3, the third connection portion 24 is inserted into the through hole, and the nozzle 25 can spray the cleaning liquid towards the heat exchanger 4.

[0042] It should be noted that the connection method between the bracket 3 and the heat exchanger 4 is not fixed. For example, it can be connected by means of screw connection, clamping or welding, etc.; and the structure of the bracket 3 is not fixed either. Its structure and the installation position with respect to the heat exchanger 4 should be determined comprehensively according to actual situations such as the spraying distance and spraying angle requirements of the nozzle 25, etc. Preferably, as Figure 3 shown, the bracket 3 in this embodiment is fixed to the housing of the heat exchanger 4, and after their connection, it can meet the cleaning coverage of more than 90% of the surface of the heat exchanger 4.

[0043] According to the heat exchanger cleaning device of the present utility model, the cleaning liquid can be introduced into the water chamber through the liquid inlet portion connected to the water pump, and the cleaning liquid can be sprayed out through a plurality of nozzles 25; each water chamber is filled with the cleaning liquid, so that a plurality of nozzles 25 can spray the cleaning liquid simultaneously; in addition, the nozzle 25 can atomize the cleaning liquid to improve the spraying uniformity. In this way, the cleaning effect on the heat exchanger 4 is effectively improved. In addition, the liquid storage portion is connected to the housing through the bracket 3, and by adjusting the shape and structure of the bracket 3, the spraying angle and spraying distance of the nozzle 25 can be flexibly adjusted to facilitate improving the cleaning effect.

[0044] Finally, it should be noted that: the above-mentioned embodiments are only specific implementation manners of the present application, used to illustrate the technical solutions of the present application, rather than limiting it. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: any person skilled in the art within the technical scope disclosed by the present application can still modify the technical solutions recorded in the foregoing embodiments or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered within the protection scope of the present application.
