Description

Technical Field

[0001] This application relates to, but is not limited to, the field of air conditioning equipment technology, specifically referring to a heat pump device. Background Technology

[0002] A heat pump device includes a housing, a partition plate, an electrical control box, a heat pump system, and a fan assembly. The partition plate is erected within the housing and divides the interior of the housing into a heat exchange chamber and an installation chamber. The heat exchange chamber is located on the left side of the installation chamber, and the partition plate has a first connecting opening. The electrical control box is located within the installation chamber and mounted on the partition plate. The electrical control box contains a control board, an air passage, and a radiator. The radiator is fixed to the control board with screws. A first air outlet of the air passage communicates with the installation chamber, and a second air outlet of the air passage communicates with the heat exchange chamber through the first connecting opening. The heat pump system has heat exchange tubes, a portion of which is placed within the electrical control box and passes through the radiator. The fan assembly is located within the heat exchange chamber. When the heat pump device operates, the fan assembly creates an airflow from the first air outlet to the second air outlet within the air passage. The heat pump system causes refrigerant to flow through the heat exchange tubes. Both the airflow through the control board and the refrigerant flowing through the heat exchange tubes dissipate heat and cool the control board. Although the heat dissipation effect of this solution's control board is very good, the process of disassembling and assembling the heat exchanger during the maintenance of the control board requires adjusting the position of the heat exchange tubes, which can easily cause the weld joints of the heat exchange tubes to crack and leak.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0022] The heat pump equipment provided in the embodiments of this application, such as Figures 1 to 9As shown, it includes: a housing 100; a partition 200, which is erected inside the housing 100 and divides the interior of the housing 100 into a heat exchange chamber 110 and an installation chamber 120, the heat exchange chamber 110 and the installation chamber 120 being arranged sequentially in a first direction; and an electrical control box 300, which is disposed inside the installation chamber 120 and includes a box body 330, a radiator 320, and a control board 310, the control board 310 being at least partially disposed inside the box body 330. Heater 320 is located on one side of control board 310 and mounted on housing 330. Control board 310 is designed for detachment from the side facing away from heater 320. Control board 310 has a second heating element 312, which abuts against the portion of housing 330 where heater 320 is mounted. A heat pump system is also included, with heat exchange pipe 410 thermally connected to housing 330 for dissipating heat from the second heating element 312. Alternatively, heat exchange pipe 410 may be positioned between heater 320 and housing 330.

[0023] The radiator 320 is located on one side of the control board 310 and is mounted on the housing 330. The heat exchange tube 410 is configured to be thermally connected to the housing 330. If the heat exchange tube 410 is located between the radiator 320 and the housing 330, the second heating element 312 of the control board 310 abuts against the part of the housing 330 where the radiator 320 is mounted, and heat dissipation and cooling are achieved at least through the refrigerant flowing through the heat exchange tube 410. In this scheme, the control board 310 is disassembled and installed on the side of the control board 310 away from the radiator 320. Thus, the process of disassembling and installing the control board 310 does not require disassembling the radiator 320. Therefore, the position of the heat exchange tube 410 in the installation chamber 120 will never change, so the weld joint of the heat exchange tube 410 will not crack or leak. Moreover, the process of disassembling and installing the control board 310 is simpler because it does not require disassembling the radiator 320. Furthermore, since the temperature of the housing 330 is lower than that of the second heating device 312, the heat from the second heating device 312 will also be transferred to the housing 330 and dissipated through the housing 330, thus further improving the heat dissipation effect of the second heating device 312.

[0024] In some embodiments, the partition 200 is provided with a first communication port 210, the interior of the box 330 has an air passage 340, the control board 310 is also provided with a first heating element 311, the first heating element 311 is located in the air passage 340, the first air outlet 341 of the air passage 340 is connected to the mounting chamber 120, and the second air outlet 342 of the air passage 340 is connected to the heat exchange chamber 110 through the first communication port 210.

[0025] The box 330 has an internal air passage 340. The first heating element 311 of the control board 310 is located inside the air passage 340. It is cooled down by the airflow passing through the air passage 340, so the heat dissipation effect of the first heating element 311 is good.

[0026] It can be, such as Figures 2 to 7 , Figure 9 As shown, the first direction is left-right, and the electrical control box 300 is vertically installed along the left-right direction. The air passage 340 is located in front of the control board 310, and the heat sink 320 is located behind the control board 310. The control board 310 is installed and removed from the front of the mounting chamber 120. At this time, the first heating element 311 is cooled by the airflow passing through the air passage 340, and the second heating element 312 is cooled by the refrigerant flowing through the heat exchange tube 410. Alternatively, the first direction is left-right, and the electrical control box 300 is vertically installed along the left-right direction. The air passage 340 is located behind the control board 310, and the heat sink 320 is located behind the control board 310. The control board 310 is installed and removed from the front of the mounting chamber 120. At this time, the first heating element 311 is cooled by the airflow passing through the air passage 340, and the second heating element 312 is cooled by the refrigerant flowing through the heat exchange tube 410. The heating element 312 is cooled not only by the airflow through the air channel 340, but also by the refrigerant flowing through the heat exchange tube 410; alternatively, the first direction is left-right, the control box 300 is vertically arranged in the front-back direction, the air channel 340 is located on the side of the control board 310 away from the middle partition 200, the radiator 320 is located on the side of the control board 310 adjacent to the middle partition 200, and the control board 310 is disassembled from the side away from the middle partition 200. In this case, the first heating element 311 is cooled by the airflow through the air channel 340, and the second heating element 312 is cooled by the refrigerant flowing through the heat exchange tube 410, etc.; all of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model, so they will not be elaborated here, and should all fall within the protection scope of this application.

[0027] like Figures 2 to 7 , Figure 9 As shown, taking the first direction as the left-right direction, the electrical control box 300 is vertically installed along the left-right direction. The air passage 340 is located on the front side of the control board 310, and the heat sink 320 is located on the rear side of the control board 310. The control board 310 is disassembled and installed from the front side of the mounting chamber 120 as an example: In some examples, the radiator 320 is at least partially located outside the housing 330, and the heat exchange pipe 410 is located outside the housing 330, situated between the portion of the radiator 320 located outside the housing 330 and the housing 330. Compared to a technical solution where the heat exchange pipe 410 is installed inside the housing 330, this solution simplifies the installation process by installing the heat exchange pipe 410 outside the housing 330.

[0028] In some examples, such as Figure 6 , Figure 7 and Figure 9 As shown, the radiator 320 includes: a first heat-conducting element 321, located outside the housing 330 and disposed on the housing 330, with a heat exchange tube 410 disposed between the first heat-conducting element 321 and the housing 330; and a second heat-conducting element 322, located inside the housing 330 and disposed on the portion of the housing 330 where the first heat-conducting element 321 is disposed, with a second heating element 312 abutting against the second heat-conducting element 322. Wherein, as... Figure 6 and Figure 7 As shown, after the first threaded connector passes through the second heat-conducting element 322 and the part of the box 330 where the first heat-conducting element 321 is located, it is screwed onto the first heat-conducting element 321, thereby fixing the first heat-conducting element 321, the second heat-conducting element 322 and the heat exchange tube 410 onto the box 330. This solution has a simple structure and is easy to operate.

[0029] In some embodiments of the utility model, such as Figure 6 , Figure 7 and Figure 9 As shown, the portion of the housing 330 where the first heat-conducting element 321 is located has a first receiving groove (the first receiving groove can be made by stamping, which is a simple manufacturing method) that is recessed towards the outside of the housing 330 and protrudes towards the inside of the housing 330. The first heat-conducting element 321 has a second receiving groove, and the second heat-conducting element 322 has a third receiving groove. The first and second receiving grooves are opposite to each other and form a receiving hole. The heat exchange tube 410 passes through the receiving hole and abuts against the wall of the receiving hole. The groove wall of the first receiving groove is placed in the third receiving groove and abuts against the groove wall of the third receiving groove. In this design, the contact area between the heat exchange tube 410 and the housing 330 and the first heat-conducting element 321 is large, and the contact area between the second heat-conducting element 322 and the housing 330 is also large. This allows the heat exchange tube 410 to better dissipate heat and cool the second heat-generating device 312.

[0030] It can be, such as Figure 6 , Figure 7 and Figure 9As shown, the receiving hole includes four parallel through holes, and the heat exchange tube 410 includes two U-shaped tubes, with the four straight tube segments of the two U-shaped tubes correspondingly inserted into the four through holes; or the receiving hole may include two parallel through holes, and the heat exchange tube 410 may include one U-shaped tube, with the two straight tube segments of the one U-shaped tube correspondingly inserted into the two through holes, etc.; all of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model, and will not be elaborated here, and should all fall within the protection scope of this application.

[0031] To ensure close contact between the second heating element 312 and the second heat-conducting element 322, such as Figure 9 As shown, this application uses a second threaded connector that passes sequentially through the second heating element 312, the second heat-conducting element 322, and the housing 330 and is screwed onto the first heat-conducting element 321, thus fixing the second heating element 312, the second heat-conducting element 322, the housing 330, and the first heat-conducting element 321 together. This solution has a simple structure and ensures good tight contact between the second heating element 312 and the second heat-conducting element 322.

[0032] Alternatively, the radiator 320 may include only the first heat-conducting element 321 and exclude the second heat-conducting element 322, with the second heating element 312 directly abutting against the housing 330 (not shown in this embodiment); or the radiator 320 may include only the second heat-conducting element 322 and exclude the first heat-conducting element 321, with the heat exchange pipe 410 located inside the housing 330, the housing 330 and the second heat-conducting element 322 forming a receiving hole, and the heat exchange pipe 410 passing through the receiving hole, etc. All of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model, so they will not be elaborated here, and should all fall within the protection scope of this application.

[0033] In some examples, such as Figure 6 and Figure 9 As shown, the electrical control box 300 further includes: a first mounting bracket 350 with a clearance opening, the first mounting bracket 350 being at least partially disposed within the box body 330 and located between the control board 310 and the heat sink 320, the control board 310 being disposed on the first mounting bracket 350 and assembled together with the first mounting bracket 350, the second heating device 312 passing through the clearance opening and abutting against the portion of the box body 330 where the heat sink 320 is located, and the air passage 340 being located on the side of the control board 310 facing away from the heat sink 320. The first mounting bracket 350 is configured as an insulating component, and the insulating component can be made of plastic, thus reducing the manufacturing cost of the first mounting bracket 350.

[0034] It is possible that the materials of the box body 330, the first heat-conducting component 321, and the second heat-conducting component 322 are all metals with good thermal conductivity. The metals can be aluminum, aluminum alloy, or stainless steel, etc. All of the above can achieve the purpose of this application. Their purpose has not deviated from the design concept of this utility model, and will not be elaborated here. They should all fall within the protection scope of this application.

[0035] In some embodiments, such as Figure 2 and Figure 3 As shown, the housing 330 includes: a second mounting bracket 331, which is vertically arranged in the left-right direction; a first mounting bracket 350 and a radiator 320 are both mounted on the second mounting bracket 331 (possibly, the radiator 320 and heat exchange tube 410 are mounted on the second mounting bracket 331, the first mounting bracket 350 and the control board 310 are assembled together, and then the assembled first mounting bracket 350 and the control board 310 are mounted together on the second mounting bracket 331 and screwed on with a second threaded connector), and the first mounting bracket 350 is located in front of the radiator 320; and a front-closed cover 360, which is located in front of the first mounting bracket 350 and is mounted on the combined structure of the first mounting bracket 350 and the control board 310; a first heating element 311 is located inside the cover 360; and an air passage 340 is located between the cover 360 and the control board 310, with the first direction being the left-right direction. In this design, the cover 360 and the front wall of the installation chamber 120 are spaced apart to avoid mutual interference due to assembly errors during the installation of the heat pump equipment.

[0036] Among them, such as Figure 3 As shown, the first air vent 341 is located on the lower part of the lower side wall or the lower part of the front side wall of the cover 360. The first mounting bracket 350 has a forward-bent folded edge 333 at one end near the middle partition 200. The second air vent 342 is located on the upper part of the folded edge 333. The side of the cover 360 facing the middle partition 200 is open and cooperates with the folded edge 333 to close it. The air passage 340 is located between the cover 340, the folded edge 333 and the control plate 310.

[0037] In other embodiments, such as Figures 4 to 9As shown, the housing 330 includes: a second mounting bracket 331, which is vertically arranged along the left-right direction; a first mounting bracket 350 and a radiator 320 are both mounted on the second mounting bracket 331, with the first mounting bracket 350 located in front of the radiator 320; and a front-to-back connecting panel 332, located in front of the first mounting bracket 350 and mounted on the combined structure of the first mounting bracket 350 and the control board 310. A first heating element 311 is located inside the connecting panel 332, and the front end of the connecting panel 332 abuts against the front wall of the mounting chamber 120. An air passage 340 is located between the front wall of the mounting chamber 120, the connecting panel 332, and the control board 310, with the first direction being the left-right direction. This design results in a lower manufacturing cost for the housing 330.

[0038] It could be that the enclosure 332 is a closed ring structure, with the second air vent 342 located on the upper part of the side wall of the enclosure 332 adjacent to the middle partition 200, and the first air vent 341 located on the lower part of the enclosure 332; or it could be, as... Figures 5 to 7 , Figure 9 As shown, the first mounting bracket 350 has a forward-bent flange 333 at one end near the middle partition 200. The second air vent 342 is located above the flange 333. The surrounding plate 332 has an open annular structure. The side of the surrounding plate 332 facing the middle partition 200 is open and cooperates with the flange 333 to close it. The front end of the flange 333 and the front end of the surrounding plate 332 abut against the front side wall of the mounting chamber 120 to seal it. The air passage 340 is located between the front side wall of the mounting chamber 120, the surrounding plate 332, the flange 333 and the control plate 310. The first air vent 341 is located at the lower part of the surrounding plate 332. All of the above can achieve the purpose of this application. The purpose has not departed from the design concept of this utility model. It will not be repeated here. All of them should be within the protection scope of this application.

[0039] In some examples, such as Figure 3 and Figure 4 As shown, the control board 310 includes a first part 313 and a second part 314. The first part 313 is located inside the box 330 and is provided with a first heating device 311 and a second heating device 312. The second part 314 is located outside the box 330 and is provided with a wiring terminal 315. The wiring terminal 315 is arranged facing forward, which makes it easier for the control box 300 to make external connections.

[0040] It can be, such as Figure 3 and Figure 4As shown, the second part 314 is located on the side of the first part 313 away from the partition 200; or the second part 314 may be located on the upper side of the first part 313; or the second part 314 may be located on the lower side of the first part 313, etc.; all of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model, and will not be repeated here, and should all fall within the protection scope of this application.

[0041] In some examples, such as Figure 1 As shown, the heat pump equipment also includes: a fan assembly 500, which is located within the heat exchange chamber 110. The heat pump system includes an outdoor heat exchanger, a compressor, connecting pipes, and heat exchange tubes 410. The outdoor heat exchanger is located within the heat exchange chamber 110 and behind the fan assembly 500. The compressor is located within the mounting chamber 120 and below the electrical control box 300. The connecting pipes connect the compressor and the outdoor heat exchanger, and the connecting pipes include heat exchange tubes 41 (e.g., heat exchange tubes 410 are located between the outlet of the outdoor heat exchanger and a throttling component on the connecting pipes). When the fan assembly 500 operates, an airflow is formed inside the air passage 340, flowing from the first air outlet 341 to the second air outlet 342.

[0042] The air conditioner provided in this application embodiment (not shown in the figure) includes the heat pump device described in any of the above embodiments.

[0043] This air conditioner possesses all the advantages of the heat pump equipment provided in any of the above embodiments, which will not be repeated here. The heat pump equipment is configured as the outdoor unit of the air conditioner.

[0044] In summary, the technical solution provided in this application embodiment has an internal air passage in the housing, a radiator located on one side of the control board and mounted on the housing, and a heat exchange tube located between the radiator and the housing. The first heating element of the control board is located in the air passage and is cooled by the airflow passing through the air passage. The second heating element of the control board abuts against the portion of the housing where the radiator is mounted and is cooled by the refrigerant flowing through the heat exchange tube. This solution allows the control board to be installed and removed from the side of the control board facing away from the radiator. This means that the process of installing and removing the control board does not require the removal of the radiator. Therefore, the position of the heat exchange tube in the installation chamber will never change, and the weld joint of the heat exchange tube will not crack or leak. Moreover, the process of installing and removing the control board is simpler because it does not require the removal of the radiator.
