[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-8 This utility model provides a technical solution: a fixing structure for a heat pump plate heat exchanger, including a casing 1 and a heat exchanger body 2, and a mounting bracket 3. The mounting bracket 3 includes a first vertical plate 301 and a second vertical plate 302 perpendicularly connected to the first vertical plate 301. The bottom of the first vertical plate 301 is provided with a horizontal inner folded edge 303. The second vertical plate 302 is provided with a first through hole 304 and a horizontal outer folded edge 305 at its bottom. Two first through holes 304 are provided along the vertical direction. The heat exchanger body... A first screw 4 is provided on one side of 2. Two first screws 4 are provided along the vertical direction. The two first screws 4 pass through two first through holes 304 respectively and are connected to a first nut 5. A base 6 is provided on the inner bottom of the chassis 1. Three second screws 7 are provided on the base 6. A second through hole 306 is provided on the horizontal inner folded edge 303. Two third through holes 307 are provided on the horizontal outer folded edge 305. The three second screws 7 pass through the second through hole 306 and the two third through holes 307 respectively and are connected to a second nut 8. By passing three second screws 7 through the second through hole 304 and two third through holes 307 respectively and connecting them with three second nuts 8, the mounting bracket 3 is pre-installed and fixed. One second through hole 306 and two third through holes 307 are connected in sequence to form a triangle. The stability of the triangle improves the stability of the mounting bracket 3. By passing two first screws 4 through the two first through holes 304 respectively, the heat exchanger body 2 is positioned. Then, the two first screws 4 are connected to the two first nuts 5 respectively by threads to install and fix the heat exchanger body 2, which facilitates the installation and disassembly of the heat exchanger body 2.

[0024] To facilitate the installation of the needle valve 9, in this embodiment, preferably, a vertical outer folded edge 308 is provided on one side of the second vertical plate 302, and a groove 309 is provided on the top of the vertical outer folded edge 308. The needle valve 9 is a refrigerant charging port. The needle valve 9 is connected to the copper pipe inside the heat pump. Because the refrigerant has the characteristic of exploding when it comes into contact with fire, when the heat pump is under maintenance, the refrigerant needs to be released through the needle valve 9 before maintenance can be carried out. The groove 309 can be used to hang the needle valve 9.

[0025] To facilitate the fixing of the needle valve 9, in this embodiment, preferably, the needle valve 9 and screw 10 are also included. A fourth through hole 310 is provided in the middle of the vertical outer folded edge 308. The fourth through hole 310 is located below the groove 309. The needle valve 9 is hung on the groove 309 and is connected to a mounting plate 11. The mounting plate 11 is provided with a screw hole 12. The screw 10 passes through the fourth through hole 310 and is connected to the screw hole 12 by thread. The purpose is to initially hang and limit the needle valve 9 through the groove 309, and then fix the needle valve 9 by connecting the screw 10 to the mounting plate 11. The structure is simple and the installation is convenient.

[0026] In order to facilitate the hanging of the needle valve 9, in this embodiment, the groove 309 is preferably semi-circular. The purpose is that since the tube of the needle valve 9 is cylindrical, the semi-circular groove 309 matches the tube of the needle valve 9, which facilitates the placement of the tube of the needle valve 9 and improves the stability of hanging.

[0027] To facilitate anti-loosening and vibration resistance, in this embodiment, preferably, a spring washer 13 is sleeved on the outer side of the second screw 7. The spring washer 13 abuts against the lower side of the second nut 8. The purpose is that after the second nut 8 is tightened, the spring washer 13 uses its own elastic deformation to generate a continuous rebound force. If the vibration causes the second nut 8 to have a slight tendency to loosen, the spring washer 13 will immediately extend to compensate for this small gap, thereby always maintaining the friction force on the second nut 8, effectively preventing the second nut 8 from spontaneously rotating and loosening due to vibration, and improving the reliability of the structure.

[0028] To ensure a stable connection, in this embodiment, the first nut 5 is preferably a flange nut. The purpose is to increase the contact area with the second vertical plate 302 by using the flange surface of the first nut 5 to prevent loosening.

[0029] To facilitate further vibration reduction and noise reduction, in this embodiment, preferably, a rubber pad 14 is provided on the lower side of the base 6. The purpose of the rubber pad 14 is to effectively absorb the vibration transmission inside the chassis 1 and reduce noise.

[0030] To facilitate the installation and disassembly of the base 6, in this embodiment, preferably, a third screw 15 is fixedly connected to the inner bottom surface of the chassis 1. The third screw 15 passes through the rubber pad 14 and the base 6 in sequence and is connected to a third nut 16. The purpose is to use the cooperation of the third screw 15 and the third nut 16 to firmly connect the base 6, the rubber pad 14 and the bottom surface of the chassis 1 into a whole. This connection method has a simple structure. The installation or disassembly of the base 6 can be completed by simply tightening or loosening the third nut 16, which facilitates the maintenance or replacement of the base. At the same time, it also ensures that the rubber pad 14 is stably compressed and fully exerts its shock absorption and buffering effect.

[0031] The first upright plate 301, the second upright plate 302, the horizontal inner fold 303, the horizontal outer fold 305, and the vertical outer fold 308 can all be achieved by sheet metal bending, which simplifies the production process, reduces production costs, and improves structural stability.

[0032] The working principle and usage process of this utility model are as follows: The three second screws 7 are engaged with the second through hole 306 and the two third through holes 307, and the second nuts 8 are used to lock them in place. The mounting bracket 3 is pre-installed on the base 6 using the principle of triangle stability. Then, the heat exchanger body 2 is aligned with the first through hole 304 by the first screw 4 and locked with the first nut 5 to complete the installation. When it is necessary to disassemble the heat exchanger body 2, simply loosen the first nut 5. The operation is simple and the maintenance is convenient.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
