Description

Technical Field

[0001] The present application relates to the technical field of heat pumps, and in particular to a heat pump unit. Background Art

[0002] A heat pump unit is a device that uses thermodynamic principles to transfer heat from a low-temperature heat source to a high-temperature heat source. A heat pump unit is usually composed of a compressor, an evaporator, a condenser, and an expansion valve. Through the phase change process of the circulating working fluid at different temperatures, the heat pump unit can absorb the heat from the low-temperature heat source and release it to the high-temperature heat source to achieve heat transfer.

[0003] After searching, the announcement number is CN218526647U, which discloses a heat pump unit, which mainly includes an electric control board, a pump device and a cooling pipeline. The two ends of the cooling pipeline are respectively connected to the cooling water supply source to form a cooling circulation loop. The pump device is arranged on the cooling circulation loop. The pump device is arranged to drive the cooling water to circulate in the cooling pipeline. At least a part of the cooling pipeline is arranged near the electric control board, and a gap is formed between the cooling pipeline and the electric control board. The cooling water circulating in the cooling pipeline absorbs the heat generated when the electric control board is working, thereby reducing the temperature of the electric control board and improving the heat dissipation effect of the electric control board to achieve the purpose of cooling. The gap formed between the cooling pipeline and the electric control board prevents the electric control board from short-circuiting when encountering water.

[0004] However, the heat dissipation method of the electric control board on the existing heat pump unit often adopts two heat dissipation methods. One is to dissipate heat by air cooling. However, the heat dissipation effect will be reduced due to the low heat dissipation efficiency of the air cooling method in a high temperature environment. The other is to dissipate heat by water cooling. For the water cooling method, since the heat dissipation object is the electric control board, it is necessary to ensure that the temperature of the electric control board can be effectively reduced while also ensuring waterproofing. The existing processing method is to form a gap between the cooling pipe and the electric control board to prevent the electric control board from contacting water. Although this can play a waterproof role, it is difficult to achieve a good heat dissipation effect by only using the cooling pipe and a non-contact method.

[0005] Therefore, it is necessary to provide a heat pump unit to solve the above problems.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0042] See also Figure 1-6, the utility model provides embodiments:

[0043] like Figure 1 As shown, a heat pump unit comprises a box body 1, an electric control box 2 for controlling the heat pump unit is installed inside the box body 1, an electric control board 3 is installed inside the electric control box 2, and a heat dissipation component 4 for the electric control board 3 is installed inside the electric control box 2;

[0044] like Figure 2 As shown, the heat dissipation assembly 4 includes a heat dissipation copper tube 41, the liquid inlet end of the heat dissipation copper tube 41 is docked and installed with one end of the water inlet pipe 7, the other end of the water inlet pipe 7 is docked and installed with the water pump 5, the water pump 5 is docked and installed with the bottom of the water tank 6 through a connecting pipe, the liquid outlet end of the heat dissipation copper tube 41 is docked and installed with one end of the water outlet pipe 8, the other end of the water outlet pipe 8 is docked and installed with the top of the water tank 6, and the water tank 6 is installed inside the box body 1.

[0045] By controlling the switch of the water pump 5, the cooling water in the water tank 6 can be pumped out through the water pump 5 and introduced into the water inlet pipe 7, and then enters the liquid inlet end of the heat dissipation copper tube 41 through the water inlet pipe 7. In the process of passing through the heat dissipation copper tube 41, after taking away the heat around the heat dissipation copper tube 41, it flows into the water inlet tank 6 from the water outlet pipe 8, and thus circulates, which can circulate and take away the heat near the electronic control board 3, thereby achieving the purpose of cooling.

[0046] like Figure 3 As shown, the side wall of the heat dissipation copper tube 41 is equipped with a heat absorption mechanism 42, and the heat absorption mechanism 42 is in contact with the side wall of the electric control board 3. The heat absorption mechanism 42 includes an aluminum plate 421, a mounting port 423, an internal threaded ring 424 and a connecting column 425. The aluminum plate 421 is provided with multiple layers, and the multiple layers of aluminum plates 421 are fixedly connected by connecting columns 425. The surfaces of the uppermost and lowermost aluminum plates 421 are respectively integrally formed with threaded tubes 422. The interior of the threaded tube 422 penetrates the multiple layers of aluminum plates 421 to open a mounting port 423 for installing the heat dissipation copper tube 41, and the internal threaded ring 424 is threadedly connected to the side wall of the threaded tube 422.

[0047] The heat conductivity of the heat dissipation copper tube 41 is increased from the surface to the surface of the multiple aluminum plates 421 by using the multiple layers of aluminum plates 421, so that when cooling the electric control board 3 in the electric control box 2, a larger area can absorb the heat generated by the electric control board 3 and the heat generated by the electric control box 2;

[0048] Furthermore, the multi-layer aluminum plate 421 can be disassembled and assembled. After the multi-layer aluminum plate 421 is assembled, it can be clamped on the side wall of the heat dissipation copper tube 41 under the fixation of the internal thread ring 424, so that it can be selected whether to install the multi-layer aluminum plate 421 according to actual needs.

[0049] Furthermore, the heat dissipation copper tube 41 is installed in a wave shape inside the multi-layer aluminum plate 421, and the surface of the heat dissipation copper tube 41 contacts the multi-layer aluminum plate 421, so as to increase the contact area between the heat dissipation copper tube 41 and the multi-layer aluminum plate 421, so as to better perform heat absorption treatment.

[0050] In order to remove the water droplets generated when condensation occurs on the heat dissipation copper tube 41 and the aluminum plate 421 to prevent damage to the electric control board 3, the side wall of the heat absorption mechanism 42 is equipped with a water removal mechanism 43 for removing the water droplets on the side wall of the heat absorption mechanism 42 and the heat dissipation copper tube 41. Figure 6 As shown, the water removal mechanism 43 includes a bellows 431, a first rotating shaft 432 and a fan blade 433. The bellows 431 is fixedly mounted on the side wall of the multi-layer aluminum plate 421 by screws, the first rotating shaft 432 is rotatably mounted inside the bellows 431 through a bearing and extends to the outside, one end of the first rotating shaft 432 is fixedly mounted with the second rotating shaft 443 through a coupling, and the other end of the first rotating shaft 432 is connected to the internal key of the fan blade 433.

[0051] The fan blades 433 are driven by the first rotating shaft 432 to blow air to the multi-layer aluminum plates 421 in the wind box 431, thereby accelerating the air flow in the gaps between the multi-layer aluminum plates 421, so that the generated water droplets can evaporate again, thereby preventing the water droplets from entering the electric control board 3.

[0052] In addition, while removing the water droplets, the first rotating shaft 432 is not driven to rotate by electric means, and the side wall of the heat dissipation copper tube 41 is also fixedly connected with a driving mechanism 44, which is installed with the water removal mechanism 43 through a coupling and provides power for the water removal mechanism 43;

[0053] Specifically, Figure 5 As shown, the driving mechanism 44 includes a liquid inlet pipe 441, a fixed disk 442, a second rotating shaft 443 and a liquid outlet pipe 445. One end of the liquid inlet pipe 441 is fixedly connected to the liquid inlet end side wall of the heat dissipation copper tube 41 located outside the heat absorption mechanism 42. The interior of the fixed disk 442 is a cavity. The interior of the fixed disk 442 is rotatably connected to the second rotating shaft 443. The side walls of the second rotating shaft 443 are respectively provided with blades 444. The other end of the liquid inlet pipe 441 is fixedly connected to the bottom of the fixed disk 442. The top of the fixed disk 442 is fixedly connected to one end of the liquid outlet pipe 445. The other end of the liquid outlet pipe 445 is fixedly connected to the liquid outlet end side wall of the heat dissipation copper tube 41 located outside the heat absorption mechanism 42.

[0054] The fixed positions of the liquid inlet pipe 441 and the liquid outlet pipe 445 and the fixed plate 442 are set off the axis, and the liquid inlet pipe 441, the liquid outlet pipe 445, the fixed plate 442 and the interior of the heat dissipation copper tube 41 are connected.

[0055] When in use, when cooling water enters the heat dissipation copper tube 41 through the liquid inlet end of the heat dissipation copper tube 41, a part of the cooling water enters the inner cavity of the fixed disk 442 through the liquid inlet pipe 441. Since the fixed positions of the liquid inlet pipe 441 and the liquid outlet pipe 445 and the fixed disk 442 are set off-axis, the water flow pushes the multiple blades 444 on the side wall of the second rotating shaft 443 to rotate with the second rotating shaft 443 as the center, so that the second rotating shaft 443 can rotate, thereby driving the first rotating shaft 432 to rotate, and then providing power for the water removal mechanism 43.

[0056] It is worth noting that in order to ensure the sealing of the water circulation and prevent water leakage, sealing rings are installed at the joints between the heat dissipation copper tube 41, the water inlet pipe 7, the water outlet pipe 8, the water pump 5 and the water tank 6 to ensure airtightness.

[0057] As an optimization solution of the present application, a fixing part 9 is also fixedly installed on the top surface of the aluminum plate 421, and the fixing part 9 includes a fixing rod 91 and a mounting plate 92. The bottom end of the fixing rod 91 is fixedly installed on the top surface of the aluminum plate 421, and the top end of the fixing rod 91 is fixedly connected to one side of the bottom surface of the mounting plate 92. A long waist groove 93 is opened on the other side of the mounting plate 92. The mounting plate 92 is installed on the inner side wall of the electric control box 2 through the long waist groove 93 and the threaded fasteners. In order to enable the multi-layer aluminum plate 421 to contact the electric control board 3, the position of the long waist groove 93 on the threaded fastener is adjusted to adjust the distance between the multi-layer aluminum plate 421 and the electric control board 3, thereby providing a better installation method.

[0058] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
