Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a self-cleaning heat exchanger component. Background Art

[0002] Heat exchangers are energy-saving devices that transfer heat between two or more fluids at different temperatures. They play a vital role in chemical, petroleum, power, food, and many other industrial processes. In harsh air environments, after a heat exchanger has been used for a period of time, dust escaping through the filter can adhere to the heat exchanger's aluminum foil, increasing the heat exchanger's windage and reducing heat transfer efficiency, impacting the air conditioning system's effectiveness. Therefore, regular cleaning of the heat exchanger is essential.

[0003] Normally, if a heat exchanger is to be cleaned, it needs to be shut down and disassembled before cleaning. This not only affects production efficiency and is time-consuming and labor-intensive, but also requires space to be reserved for disassembling the heat exchanger during installation, which increases the space required for installation and causes space waste.

[0004] Therefore, there is an urgent need for a self-cleaning heat exchanger assembly to solve the above problems. Utility Model Content

[0033] like Figures 1 to 2 As shown, the self-cleaning heat exchanger assembly of this embodiment includes a heat exchanger 1, a cleaning mechanism 2, and a protective cover 3. The cleaning mechanism 2 is disposed on one side of the heat exchanger 1 and includes a water inlet pipe 21, a nozzle 22, and a water pump. The nozzle 22 is connected to the end of the water inlet pipe 21 and is disposed toward the heat exchanger 1. The water pump is connected to the water inlet pipe 21 and can supply water to the water inlet pipe 21. The protective cover 3 is enclosed to form a receiving space 31. The heat exchanger 1 and the cleaning mechanism 2 are disposed in the receiving space 31. The front end of the water inlet pipe 21 extends out of the protective cover 3 for connection to a water supply device.

[0034] Based on the above design, the self-cleaning heat exchanger assembly of this embodiment sets the heat exchanger 1 and the cleaning mechanism 2 in the protective cover 3. The cleaning mechanism 2 includes a water pump, a water inlet pipe 21 and a nozzle 22. One end of the water inlet pipe 21 is connected to the nozzle 22, and the other end extends outside the protective cover 3 and is connected to the water pump. When the heat exchanger 1 needs to be cleaned, the water pump is turned on to supply water to the water inlet pipe 21, and the heat exchanger 1 is flushed through the nozzle 22; when the cleaning is completed, the water pump is turned off. The self-cleaning heat exchanger assembly can be cleaned without disassembling the heat exchanger, which saves the workload of disassembling and assembling the heat exchanger. Cleaning can be completed by controlling the switch of the water pump, simplifying the operating process and improving work efficiency. There is no need to reserve space for disassembling and assembling the heat exchanger, thereby reducing the occupied space and saving production costs.

[0035] Furthermore, the cleaning mechanism 2 includes a first movable structure 23, to which the nozzle 22 is slidably connected along a first direction, which is the X direction in the figure. The provision of the first movable structure 23 enables the nozzle 22 to move in the first direction, thereby improving the flexibility of the cleaning mechanism 2 in flushing the heat exchanger 1 and ensuring cleaning efficiency.

[0036] Furthermore, the cleaning mechanism 2 also includes a second movable structure 24, which is slidably connected to the first movable structure 23 along the first direction, and the nozzle 22 is slidably connected to the second movable structure 24 along the second direction. The first direction and the second direction are set at an angle. In this embodiment, the second direction is the Y direction in the figure, and the second direction is perpendicular to the first direction.

[0037] By setting the first movable structure 23 and the second movable structure 24, the position of the projection of the nozzle 22 on the surface of the heat exchanger 1 facing the nozzle 22 can be changed, so that the flushing coverage of the heat exchanger 1 by the nozzle 22 is expanded, and the positions with more impurities can be flushed intensively, and dead corners and narrow areas that are not cleaned properly can be prevented, so that the cleaning is more comprehensive and the quality of the flushing is guaranteed.

[0038] Specifically, the first movable structure 23 includes a first guide member 231, a first sliding member 232 and a first driving member. The first guide member 231 is fixed in the accommodating space 31 and extends along the first direction. The first sliding member 232 is connected to the first guide member 231 for sliding along the first direction. The first driving member can drive the first sliding member 232 to move on the first guide member 231. The nozzle 22 is connected to the first sliding member 232, so that the first driving member can drive the nozzle 22 to move in the first direction.

[0039] In this embodiment, the top and bottom of the first guide member 231 are respectively connected to the top wall and the bottom wall of the protective cover 3, thereby ensuring the stability of the cleaning mechanism 2.

[0040] Specifically, the second movable structure 24 includes a second guide member 241, a second sliding member 242 and a second driving member. The second guide member 241 extends along the second direction, the second guide member 241 is connected to the first sliding member 232, the second sliding member 242 is connected to the second guide member 241 for sliding along the second direction, and the second driving member can drive the second sliding member 242 to slide on the second guide member 241. The nozzle 22 is connected to the second sliding member 242 to realize the movement of the nozzle 22 in the second direction.

[0041] In this embodiment, the self-cleaning heat exchanger assembly also includes a controller, which can be a centralized or distributed controller. For example, the controller can be a single single-chip microcomputer or a distributed multiple single-chip microcomputer. The control program can be run in the controller to control the water pump, the first drive member and the second drive member to realize their functions.

[0042] Furthermore, the self-cleaning heat exchanger assembly also includes a water collecting part 4, which is arranged in the accommodating space 31 and located below the heat exchanger 1 and the cleaning mechanism 2. The water collecting part 4 can receive water flow for flushing the heat exchanger 1 to prevent the sewage after cleaning from polluting the working environment.

[0043] Specifically, the water collecting part 4 includes a water receiving tray 41 and a drain pipe 42. The water receiving tray 41 is located below the heat exchanger 1 and the cleaning mechanism 2 and is used to receive sewage. One end of the drain pipe 42 is connected to the water receiving tray 41, and the other end extends out of the protective cover 3 to discharge the sewage from the accommodating space 31.

[0044] Optionally, the water collecting member 4 is connected to the bottom of the cleaning mechanism 2 to ensure the stability of the water collecting member 4 and the cleaning mechanism 2.

[0045] Furthermore, the protective cover 3 is provided with an observation window 32 and a protective door 33, both of which are provided on the side walls of the protective cover 3. Through the observation window 32, the thickness of dust on the surface of the heat exchanger 1 can be observed, and it can be observed whether the cleaning is complete, so as to decide whether to clean the heat exchanger 1 and when to end the cleaning. The protective door 33 allows maintenance of the heat exchanger 1 and the cleaning mechanism 2.

[0046] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
