The terms used herein in this specification are only for the purpose of describing specific embodiments and are not intended to limit this specification. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0054] The embodiments of this specification provide a heat pump. Figures 1 to 6 The three-dimensional structure diagram, front view, rear view, side view, top view and bottom view of the heat pump in one embodiment of the present specification are shown respectively. Figures 1 to 4 As shown, the heat pump may include a fan 10, a first space 20, and a second space 30. Figures 1 to 4 As shown, the fan 10, the first space 20 and the second space 30 are arranged in sequence from top to bottom. A first heat exchanger 201 is arranged in the first space 20. The refrigerant flowing through the first heat exchanger 201 exchanges heat with the outside air. A variable frequency compressor and a second heat exchanger (not shown in the figure) are arranged in the second space 30. The refrigerant flowing through the second heat exchanger heats the water in the second space 30 (fluorine water heat exchange). The first heat exchanger 201 can be an evaporator. The second heat exchanger can be a condenser.

[0055] like Figure 1 , Figure 2 and Figure 6 As shown, the heat pump may further include a drive plate assembly 40 .

[0056] Please refer to Figures 7 to 11 , respectively showing a three-dimensional structure diagram, an open cover three-dimensional structure diagram, a top view, a bottom view and a side view of the drive board assembly in the embodiment of this specification. Figure 7 , Figure 8 and Fig.11 As shown, the drive board assembly 40 may include a mounting box 401, a drive board (not shown in the figure), a shroud 403, and a radiator 405. The drive board may be mounted on one side of the mounting box 401, and the shroud 403 may be located on the other side of the mounting box 401. Since the radiator 405 and the drive board are mounted on both sides of the mounting box 401, respectively, the radiator 405 may absorb the heat generated by the drive board by heat conduction and dissipate the absorbed heat into the surrounding air, thereby dissipating the heat of the drive board.

[0057] The air guide cover 403 and the installation box 401 form an air guide channel 404. The heat sink 405 is located in the air guide channel 404.

[0058] like Figure 1 and Figure 6As shown, the heat pump may further include a heat pump housing 50. The mounting box 401 is mounted on the heat pump housing 50. The air guide cover 403 may be mounted on the heat pump housing 50 or on the other side of the mounting box 401. The air guide cover 403 and the air guide channel 404 are located inside the heat pump housing 50, and may be partially located inside the heat pump housing 50, or may be completely located inside the heat pump housing, which is not limited here. The outlet of the air guide channel 404 is connected to the inlet of the fan 10.

[0059] The installation box 401 may have an air inlet and an air outlet. The air inlet may be connected to the outside. In one embodiment, the air inlet may be an opening on the installation box 401, for example, the installation box 401 is a box body with an open top. In another embodiment, the air inlet may be an opening on the installation box 401, for example, the air inlet may be an opening on the cover plate or the side plate of the installation box 401. When the fan 10 is running, outside air can enter the installation box 401 through the air inlet, flow through the drive board and then flow to the air outlet to take away at least part of the heat generated by the drive board. The air guide cover 403 covers the air outlet so that the gas flowing out of the air outlet enters the guide channel 404 and flows through the radiator 405 to take away the heat conducted to the radiator 405 by the drive board.

[0060] That is to say, when the fan 10 is running, the outside air can flow through the drive plate through the air inlet, then flow through the radiator 405 located in the guide channel 404 through the air outlet, and then flow to the inlet of the fan 10 through the outlet of the guide channel 404, thereby achieving heat dissipation for the drive plate.

[0061] In the above embodiment, the guide channel 404 and the first space 20 reuse a fan 10. When the fan 10 is running, the outside air can first enter the installation box 401 through the air inlet and flow through the drive board and then flow through the radiator 405 through the air outlet, which can achieve double heat dissipation of the drive board, thereby improving the heat dissipation efficiency of the drive board. Furthermore, since the radiator 405 is arranged in the guide cover 403, the constant airflow in the guide channel can be fully in contact with the radiator 405, thereby improving the heat dissipation efficiency of the radiator 405, thereby further improving the heat dissipation effect.

[0062] like Fig.11 As shown, in some embodiments of the present specification, the heat sink 405 may include a plurality of heat sinks arranged side by side. By arranging a plurality of heat sinks arranged side by side, the heat dissipation area of ​​the heat sink 405 may be increased, thereby improving the heat dissipation effect. Furthermore, the extension direction of the heat sink fins may be set to be consistent with the direction of the airflow path in the guide channel 404, that is, the extension direction of the heat sink fins may be set to be consistent with the outlet direction of the guide channel, so that as much air as possible flows through the heat sink, thereby improving the heat dissipation speed of the heat sink.

[0063] like Figures 1 to 6 As shown, in some embodiments of the present specification, the fan 10 is arranged above the air deflector 403. The outlet direction of the air deflector 403 can be deviated from the inlet of the fan 10 to prevent rainwater from entering the guide channel 404, thereby preventing rainwater from entering the drive board inside the installation box 401 through the air outlet and causing the drive board to fail.

[0064] like Figure 7 and Figure 8 As shown, in some embodiments of the present specification, the air guide cover 403 extends in the horizontal direction, that is, the outlet direction of the air guide channel 404 is in the horizontal direction. Compared with setting the outlet direction of the air guide channel 404 to be inclined downward or vertically downward, in this embodiment, by setting the air guide cover 403 to extend in the horizontal direction, not only can the rainproof effect of the drive plate assembly 40 be ensured, but also the fan 10 can be better reused, and the air flow velocity in the air guide channel 404 can be increased, thereby improving the heat dissipation effect.

[0065] like Figure 6 As shown, in some embodiments of the present specification, the drive board is installed on one side of the installation box 401, the air deflector 403 is installed on the other side of the installation box 401, and the radiator 403 is arranged in the air deflector channel surrounded by the air deflector 403 and the installation box 401. The heat pump housing 50 is provided with a through hole, and the through hole is used for the air deflector 403 to extend into the interior of the heat pump housing 50. In this case, the drive board assembly 40 can be used as a whole. By providing a through hole on the heat pump housing 50, the installation and disassembly of the drive board assembly 40 as a whole can be realized, and the operation is simple and convenient.

[0066] In some embodiments of the present specification, the first space 20 and the second space 30 are isolated from each other. The inlet of the fan 10 is connected to the first space 20. Figure 6 As shown, the air guide cover 403 extends into the first space 20 through the through hole. In this embodiment, since the first space 20 and the second space 30 are isolated from each other, and the first space 20 is connected to the inlet of the fan 10, the air guide cover 403 and the heat sink 405 are installed in the first space 20, so that the fan 10 can be reused. Moreover, the first space 20 is closer to the fan 10 than the second space 30, and the wind pressure is greater, which can increase the air flow in the guide channel 404, thereby improving the heat dissipation efficiency of the drive plate 402.

[0067] like Figures 1 to 3 As shown, in some embodiments of the present specification, the first heat exchanger 201 is a V-shaped heat exchanger. The heat pump housing 50 may include a first side plate 501 and a second side plate 502 located on both sides of the V-shaped heat exchanger in the first space 20. The mounting box 401 is mounted on the first side plate 501 (such as Figure 1 or Figure 2The first side plate 501 or the second side plate 502 is provided with a through hole. The air deflector 403 is installed on the other side of the installation box 401. The air deflector 403 can extend into the interior of the heat pump housing 50 through the through hole. In this embodiment, since the wind pressure inside the V-type heat exchanger is greater than the wind pressure outside, the air deflector 403 and the radiator 405 are arranged inside the V-type heat exchanger, which can make the air flow in the guide channel 404 larger, thereby improving the heat dissipation efficiency of the drive plate 402. In addition, by providing a through hole on the heat pump housing 50, the overall installation and disassembly of the drive plate assembly 40 can be realized, and the operation is simple and convenient.

[0068] In some embodiments of the present specification, the inlet of the fan 10 is connected to the first space 20. The first space 20 is connected to the second space 30. At least the air guide cover 403 and the air guide channel 404 are arranged in the second space 30. In this embodiment, since the first space 20 is connected to the second space 30, the air guide cover 403 and the air guide channel 404 are arranged in the second space 30, and the fan 10 can also be reused to achieve heat dissipation of the drive plate 402.

[0069] In some embodiments of the present specification, a baffle is provided between the first space 20 and the second space 30. The first space 20 and the second space 30 can be connected through an air duct opening provided on the baffle. In this embodiment, the first space 20 and the second space 30 can be connected through the air duct opening on the baffle between the first space 20 and the second space 30.

[0070] In some embodiments of the present specification, the air inlet may include a first air inlet and a second air inlet. External air can flow into the installation box through the first air inlet and the second air inlet, and flow out from the air outlet. In this embodiment, the first air inlet and the second air inlet can be provided on the installation box, and the first air inlet and the second air inlet are both connected to the outside world. External air can flow into the installation box through the first air inlet and the second air inlet, flow through the drive plate, and flow out from the air outlet on the installation box. By providing the first air inlet and the second air inlet, the gas flow rate flowing into the installation box can be increased, thereby taking away more heat when flowing through the drive plate, and improving the heat dissipation efficiency.

[0071] Please refer to Fig.12 , shows a perspective view of the installation box. Fig.12As shown, in some embodiments of the present specification, the first air inlet 411 and the second air inlet 412 are arranged on the first surface of the installation box 401. The air outlet 413 is arranged on the second surface of the installation box 401 opposite to the first surface. The first air inlet 411 and the air outlet 413 are staggered in the length direction of the installation box 401. The first air inlet 411 is located on the first side of the driving plate 402. The air outlet 413 is located on the second side of the driving plate 402 opposite to the first side. The outside air flows in from the first air inlet 411 and then flows through the driving plate 402 and flows out from the air outlet 413. By staggering the first air inlet 411 and the air outlet 413 relative to the driving plate 402, the air flowing into the installation box 401 from the first air inlet 411 can flow through the driving plate 402 and then flow out from the air outlet 413, which can increase the amount of air flowing through the driving plate 402, thereby improving the heat dissipation efficiency.

[0072] like Fig.12 As shown, in some embodiments of the present specification, the second air inlet 412 is located on the second side of the driving board 402. In this embodiment, the second air inlet 412 is arranged on the second side of the driving board 402, so that the air flowing into the installation box 401 from the second air inlet 412 can flow through other electronic components on the second side of the driving board 402 and then flow out from the air outlet 413, so as to dissipate heat for other electronic components in the installation box 401.

[0073] In some embodiments of the present specification, the area of ​​the first air inlet 411 is larger than the area of ​​the second air inlet 412. In this embodiment, since the driving board 402 generates more heat than other electronic devices, the area of ​​the first air inlet 411 is set to be larger than the area of ​​the second air inlet 412, which can improve the heat dissipation efficiency of the driving board 402.

[0074] like Fig.12 As shown, in some embodiments of the present specification, the installation box 401 may further include a reactor 406. The second air inlet 412 and the air outlet 413 are staggered in the width direction of the installation box 401. In the width direction, the second air inlet 412 is arranged on a first side of the reactor 406, and the air outlet 413 is arranged on a second side of the reactor 406 opposite to the first side of the reactor 406. The outside air flows in from the second air inlet 412 and then flows through the reactor 406 and flows out from the air outlet 413. By staggering the second air inlet 412 and the air outlet 413 relative to the reactor 406, the air flowing into the installation box 401 from the second air inlet 412 can flow through the reactor 406 and then flow out from the air outlet 413, which can increase the airflow passing through the reactor 406, thereby improving the heat dissipation efficiency of the reactor 406.

[0075] Please refer to Figures 13 to 15, respectively showing a perspective view of the installation box, a schematic diagram of the partition of the installation box, and a schematic diagram of the bottom plate of the first cavity. Figures 7 to 11 and Fig.13 As shown, in some embodiments of the present specification, the installation box 401 includes a partition 408. The partition 408 separates the installation box 401 into a first cavity 409 and a second cavity 410. Fig.13 As shown, a driving plate 402 is disposed in the first cavity 409. Figure 8 and Fig.13 As shown, the main control board 407 is disposed in the second cavity 410. Fig.14 As shown, an air inlet 414 may be provided on the side plate of the second chamber 410. The first air inlet 411 and the second air inlet 412 may be connected to the outside through the air inlet 414. It is understood that the air inlet 414 may also be an opening provided on the cover plate of the second chamber 410 opposite to the partition plate 408, or the air inlet 414 may be an open opening on the second chamber 410, i.e., no cover plate is provided.

[0076] In one embodiment, Fig.10 As shown, an air inlet 414 may be provided on the lower side plate of the second cavity 410 to prevent rainwater from entering the installation box 401 through the air inlet 414 .

[0077] like Fig.13 and Fig.14 As shown, the air inlet (for example, the first air inlet 411) may be disposed on the partition 408. The partition 408 may be provided with a main control board 407. Fig.13 and Fig.15 As shown, the air outlet 413 is disposed on the bottom plate of the first chamber 409 opposite to the partition plate 408.
