Description

Technical Field

[0001] This utility model relates to the field of heat pump machines, and in particular to an air source heat pump. Background Technology

[0002] Air source heat pumps are increasingly favored by users due to their good energy-saving performance. However, in related technologies, the water-refrigerant heat exchanger in air source heat pumps has low installation efficiency and is difficult to install accurately and efficiently at the target location, indicating room for improvement. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention provides an air source heat pump, wherein the assembly efficiency of the second heat exchanger of the air source heat pump is high.

[0004] An air source heat pump according to an embodiment of the present invention includes: a housing assembly, the housing assembly including a chassis and a partition, the partition being disposed on the chassis and extending in a vertical direction, the partition dividing the space above the chassis into a first space and a second space located on both sides of the thickness of the partition, the partition including an upper partition and a lower partition arranged and assembled together in a vertical direction; a heat pump system, the heat pump system including a first heat exchanger and a second heat exchanger that switch between evaporator and condenser, and a compressor connected between the first heat exchanger and the second heat exchanger, the first heat exchanger being disposed in the first space and adapted to exchange heat with air flowing through the first heat exchanger, the second heat exchanger being disposed in the second space and including a refrigerant flow path and a water flow path that are independent of each other and exchange heat; wherein, the second heat exchanger and the lower partition are slidably fitted in a vertical direction by a guide structure, the compressor is located above the second heat exchanger, and the junction of the upper partition and the lower partition is higher than the height center of the second heat exchanger and lower than the height center of the compressor.

[0005] According to this utility model of an air source heat pump, by setting the partition as a split structure, the partition includes an upper partition and a lower partition that are assembled and connected vertically. The second heat exchanger only needs to be fitted to the lower partition through a guide structure, instead of fitting the second heat exchanger to the entire partition through a guide structure. Since the lower partition is smaller than the entire partition, this guided fitting assembly is easier, and the guide fitting distance is relatively shorter, making it easier to control. This reduces operational difficulty and improves the assembly efficiency of the second heat exchanger. Furthermore, the guided fitting of the second heat exchanger to the lower partition allows the second heat exchanger to reach the installation position more accurately, eliminating the need for position adjustment and further improving assembly efficiency.

[0054] The air source heat pump 100 of this utility model is described below with reference to the accompanying drawings.

[0055] According to an embodiment of the present utility model, the air source heat pump 100, such as Figures 1-3 As shown, the air source heat pump 100 includes: a housing assembly 1 and a heat pump system 2. The housing assembly 1 includes a chassis 11 and a partition 12. The partition 12 is disposed on the chassis 11 and extends in the vertical direction Y. The partition 12 divides the space above the chassis 11 into a first space 1a and a second space 1b located on both sides of the thickness of the partition 12. The partition 12 includes an upper partition 121 and a lower partition 122 arranged and assembled together in the vertical direction Y. The heat pump system 2 includes a first heat exchanger 21 and a second heat exchanger 22 that switch between evaporator and condenser, and a connection to the first heat exchanger 21. The compressor 23 is located between the compressor 23 and the second heat exchanger 22. The first heat exchanger 21 is located in the first space 1a and is adapted to exchange heat with the air flowing through the first heat exchanger 21. The second heat exchanger 22 is located in the second space 1b and includes independent refrigerant flow paths and water flow paths that exchange heat. The second heat exchanger 22 and the lower partition 122 are slidably fitted together in the vertical direction Y by the guide structure 13. The compressor 23 is located above the second heat exchanger 22. The junction position P between the upper partition 121 and the lower partition 122 is higher than the height center of the second heat exchanger 22 and lower than the height center of the compressor 23.

[0056] The air source heat pump 100 uses heat pump technology to extract low-grade heat energy from the air and then converts it into usable high-grade heat energy using electricity to provide heating and cooling services. Compared to simply using the same amount of electricity to generate heat energy, heat pump technology uses electricity to transport more heat energy, consuming only a small amount of net reverse cycle work to obtain a larger heating capacity. For example, the following explanation uses the air source heat pump 100 as an example of a rooftop / floortop heat pump unit.

[0057] The housing assembly 1 serves as the mounting carrier for the air source heat pump 100. It is worth noting that the housing assembly 1 can be an enclosed structure forming a sealed cavity or a frame structure with openings. The housing assembly 1 includes a chassis 11 and a partition 12. The partition 12 is connected to the chassis 11 and positioned above it. The partition 12 extends in the vertical direction Y, dividing the space above the chassis 11 into a first space 1a and a second space 1b located on either side of its thickness. The heat pump system 2 includes a first heat exchanger 21, a second heat exchanger 22, and a compressor 23. The first heat exchanger 21 is located in the first space 1a, and the second heat exchanger 22 and the compressor 23 are located in the second space 1b. By dividing the space above the chassis 11 into the first space 1a and the second space 1b using the partition 12, the first heat exchanger 21 and the second heat exchanger 22 can be arranged in separate chambers, resulting in a reasonable arrangement and a compact overall structure for the air source heat pump 100.

[0058] The heat pump system 2 is a functional component of the air source heat pump 100. The first heat exchanger 21 is disposed in the first space 1a and is adapted to exchange heat with the flowing air. The first heat exchanger 21 and the second heat exchanger 22 switch between serving as an evaporator and a condenser. It is understood that, in addition to the first heat exchanger 21, the second heat exchanger 22, and the compressor 23, the heat pump system 2 may also have a throttling device, a reversing valve, etc., which will not be elaborated here.

[0059] For example, when the outdoor temperature is high and indoor cooling is needed, such as in summer, compressor 23 delivers high-temperature, high-pressure gaseous refrigerant to the first heat exchanger 21, which acts as a condenser, and the second heat exchanger 22 acts as an evaporator. The refrigerant flow path in the second heat exchanger 22 exchanges heat with the water flow path, which can lower the temperature of the water flow path. Subsequently, the liquid in the water flow path can be delivered to the room to provide low-temperature water, or exchange heat with the indoor air to lower the indoor temperature.

[0060] For example, when the outdoor temperature is low and indoor heating is needed, such as in winter, the compressor 23 compresses the refrigerant and delivers the high-temperature, high-pressure gaseous refrigerant to the second heat exchanger 22. The first heat exchanger 21 acts as an evaporator, and the second heat exchanger 22 acts as a condenser. The refrigerant flow path in the second heat exchanger 22 exchanges heat with the water flow path, which can heat the water flow path. Then, the liquid in the water flow path can be delivered to the room to provide hot water, or exchange heat with the indoor air to raise the indoor temperature.

[0061] In the above technical solution, since the second heat exchanger 22 and the lower partition plate 122 slide and cooperate in the vertical direction Y through the guide structure 13, the second heat exchanger 22 can accurately and quickly reach the installation position, eliminating the position adjustment process and improving assembly efficiency.

[0062] Furthermore, the partition in the related technology is a one-piece partition along the vertical direction, and the overall size of the partition in the vertical direction is relatively large. The second heat exchanger is located below the compressor, and its arrangement position is low. Thus, if the second heat exchanger is installed on the partition via a guide structure, it is inconvenient to operate, difficult to assemble, and affects assembly efficiency.

[0063] In the air source heat pump 100 of this utility model embodiment, the partition 12 is set as a split structure. The partition 12 includes an upper partition 121 and a lower partition 122 arranged in a vertical Y direction and assembled and connected. It is only necessary to connect the second heat exchanger 22 with the lower partition 122 through the guide structure 13, instead of connecting the second heat exchanger 22 with the entire partition 12 through the guide structure 13. The lower partition 122 is smaller in size and easier to operate, thereby reducing the difficulty of operation and improving the assembly efficiency of the second heat exchanger 22.

[0064] Furthermore, the junction P of the upper partition 121 and the lower partition 122 is higher than the height center of the second heat exchanger 22. When the second heat exchanger 22 is installed on the lower partition 122, the height center of the second heat exchanger 22 is lower than the upper end of the lower partition 122. The center of gravity of the second heat exchanger 22 is lower than the upper end of the lower partition 122, which can improve the installation stability of the second heat exchanger 22 and prevent the second heat exchanger 22 from tipping over due to its high center of gravity. The compressor 23 is located above the second heat exchanger 22, and the upper end of the lower partition 122 does not exceed the height center of the compressor 23. The dimension of the lower partition 122 in the vertical direction Y is reduced, making it easier to operate the lower partition 122 and facilitating the assembly of the second heat exchanger 22 with the lower partition 122, thereby improving the assembly efficiency of the second heat exchanger 22.

[0065] According to the embodiment of the present utility model, the air source heat pump 100 has a split structure for the partition 12, which includes an upper partition 121 and a lower partition 122 that are connected vertically. The second heat exchanger 22 only needs to be connected to the lower partition 122 through the guide structure 13, instead of connecting the second heat exchanger 22 to the entire partition 12 through the guide structure 13. The lower partition 122 is smaller in size and volume, making it easier to operate, thereby reducing the difficulty of operation and improving the assembly efficiency of the second heat exchanger 22.

[0066] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the partition 12 is configured to satisfy at least one of the following three conditions: condition one is that the junction P between the upper partition 121 and the lower partition 122 is higher than or level with the upper end of the second heat exchanger 22; condition two is that the junction P between the upper partition 121 and the lower partition 122 is lower than or level with the lower end of the compressor 23; and condition three is that the height of the lower partition 122 is less than or equal to the height of the upper partition 121.

[0067] The junction P between the upper partition 121 and the lower partition 122 is higher than or level with the upper end of the second heat exchanger 22. The center of gravity of the second heat exchanger 22 is located below the junction P between the upper partition 121 and the lower partition 122. After assembling the second heat exchanger 22 and the lower partition 122, the center of gravity of the second heat exchanger 22 is stable, which can improve the situation where the second heat exchanger 22 causes the lower partition 122 to tip over.

[0068] The junction P between the upper partition 121 and the lower partition 122 is lower than or flush with the lower end of the compressor 23, and the upper end of the lower partition 122 is lower than or flush with the lower end of the compressor 23. The lower partition 122 is not connected to the compressor 23. By reducing the upper end of the lower partition 122 to be lower than or flush with the lower end of the compressor 23, the size of the lower partition 122 can be reduced, making it easier to operate and facilitating the assembly of the second heat exchanger 22 with the lower partition 122, thereby improving the assembly efficiency of the second heat exchanger 22. Furthermore, reducing the size of the lower partition 122 can also reduce installation interference with the compressor 23, which is beneficial to improving the assembly efficiency of the compressor 23.

[0069] The height of the lower partition 122 is less than or equal to the height of the upper partition 121. The height of the lower partition 122 is half or less of the overall height of the partition 12. This makes it easier to control the lower partition 122 and facilitates the assembly of the second heat exchanger 22 with the lower partition 122, thereby improving the assembly efficiency of the second heat exchanger 22.

[0070] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the width direction Z of the partition 12 is perpendicular to the thickness direction X and the vertical direction Y of the partition 12. The guide structure 13 hinders the relative movement between the second heat exchanger 22 and the lower partition 122 along the thickness direction X and / or the width direction Z of the partition 12.

[0071] The second heat exchanger 22 and the lower partition 122 are slidably engaged in the vertical direction Y via a guide structure 13. The guide structure 13 not only serves as a guide, improving the assembly efficiency of the second heat exchanger 22, but also acts as a limiter, hindering relative movement between the second heat exchanger 22 and the lower partition 122 along the thickness direction X and / or width direction Z of the partition 12, thereby improving the installation stability of the second heat exchanger 22. Furthermore, by using the guide structure 13 to limit the movement of the second heat exchanger 22, an additional limiting structure is unnecessary, thus reducing structural complexity and saving manufacturing costs.

[0072] In some embodiments of this utility model, such as Figure 4 As shown, the extension length of the guide structure 13 in the vertical direction Y is greater than half the vertical height of the lower partition 122. The second heat exchanger 22 can slide between the guide structure 13 and the lower partition 122 at least along half the vertical height of the lower partition 122. The longer engagement stroke between the second heat exchanger 22 and the lower partition 122 can improve the assembly stability of the second heat exchanger 22 and lower the center of gravity of the second heat exchanger 22.

[0073] In some embodiments of this utility model, such as Figure 4As shown, the guide structure 13 extends downward from the upper end of the lower partition 122. The second heat exchanger 22 and the guide structure 13 are engaged from the upper end of the lower partition 122. The second heat exchanger 22 is assembled with the lower partition 122 from the upper end of the lower partition 122 downward. This simplifies the assembly process of the second heat exchanger 22 and the lower partition 122 and helps to improve the assembly efficiency of the second heat exchanger 22.

[0074] In some embodiments of this utility model, such as Figure 4 As shown, the guide structure 13 extends downward from the upper end of the lower partition 122, and the extension length of the guide structure 13 in the vertical direction Y is greater than half of the vertical height of the lower partition 122.

[0075] The second heat exchanger 22 is assembled with the lower partition 122 from the upper end downwards, and the downward sliding stroke is greater than half the vertical height of the lower partition 122. This simplifies the assembly process of the second heat exchanger 22 and the lower partition 122 and improves the assembly stability of the second heat exchanger 22.

[0076] In some embodiments of this utility model, the second heat exchanger 22 and the lower partition 122 are positioned at the guide structure 13 by a positioning component to limit the relative position of the second heat exchanger 22 and the lower partition 122 in the vertical direction Y; and / or, the second heat exchanger 22 and the lower partition 122 are connected at the guide structure 13 by a first fastener so that the second heat exchanger 22 is fixedly installed on the lower partition 122.

[0077] The second heat exchanger 22 and the lower partition 122 are positioned at the guide structure 13 by a positioning component, which improves the installation stability of the second heat exchanger 22 and eliminates the need for additional positioning structures 14 at other locations on the second heat exchanger 22 and the lower partition 122, thereby reducing structural complexity. Similarly, by connecting the second heat exchanger 22 and the lower partition 122 at the guide structure 13 with a first fastener, the installation stability of the second heat exchanger 22 can be improved, and the need for additional fasteners at other locations on the second heat exchanger 22 and the lower partition 122 can be eliminated. This reduces the risk of damage to the second heat exchanger 22 during the fastening process of the first fastener, thereby improving the operational reliability of the second heat exchanger 22.

[0078] The second heat exchanger 22 and the lower partition 122 are positioned at the guide structure 13 by a positioning component, and the second heat exchanger 22 and the lower partition 122 are connected at the guide structure 13 by a first fastener. The second heat exchanger 22 and the lower partition 122 can be positioned first and then fixedly connected, which can improve the installation efficiency of the second heat exchanger 22.

[0079] In some embodiments of this utility model, such as Figure 3As shown, the guide structure 13 includes a first guide structure 131 formed on the lower partition 122 and a second guide structure 132 formed on the second heat exchanger 22. The first guide structure 131 on the lower partition 122 and the second guide structure 132 on the second heat exchanger 22 cooperate to slide in the vertical direction Y, which can improve the stability of the sliding movement.

[0080] For example, the guide structure 13 includes a guide rail formed on the lower partition 122 and a guide block formed on the second heat exchanger 22, the guide block being guided and engaged with the guide rail so that the second heat exchanger 22 slides relative to the lower partition 122 in the vertical direction Y.

[0081] In other embodiments of this utility model, such as Figure 5 As shown, guide structure 13 is formed on one of the lower partition 122 and the second heat exchanger 22, and the other of the lower partition 122 and the second heat exchanger 22 is guided and engaged with guide structure 13. Exemplarily, guide structure 13 is formed at both ends of the lower partition 122 in the width direction Z, so that the second heat exchanger 22 slides relative to the lower partition 122 in the vertical direction Y.

[0082] The form of the positioning component is not limited. For example, it may include a positioning protrusion provided on one of the lower partition plate 122 and the second heat exchanger 22, and a positioning hole provided on the other of the lower partition plate 122 and the second heat exchanger 22. When the guide structure 13 is in the guiding fit, the positioning protrusion extends into the positioning hole. The positioning protrusion can be a positioning pin or a fastening bolt, and at the same time, it serves as the first fastener.

[0083] In some embodiments of this utility model, the second heat exchanger 22 is a plate heat exchanger, and the plate heat exchanger is fixedly connected to the lower partition 122 by fasteners. Compared with the ring heat exchanger, the plate heat exchanger has a larger contact area with the lower partition 122, which facilitates the connection between the second heat exchanger 22 and the lower partition 122.

[0084] In some embodiments of this utility model, the second space 1b is further provided with a water pump 24, which is lower than the compressor 23 and connected to the water flow path; wherein, the water pump 24 is integrated with the second heat exchanger 22 as a component, or the water pump 24 is installed on the chassis 11 and / or on the carrier connected to the partition 12.

[0085] The water pump 24 is connected to the water flow path and can drive the liquid flow within the water flow path. The water pump 24 is connected to the second heat exchanger 22, so the water pump 24 and the second heat exchanger 22 can be integrated into a component. The component formed by the water pump 24 and the second heat exchanger 22 can be assembled on the lower partition 122 through the sliding fit between the second heat exchanger 22 and the lower partition 122. By setting the partition 12 as an upper partition 121 and a lower partition 122 that are connected vertically, it is only necessary to fit the component formed by the water pump 24 and the second heat exchanger 22 with the smaller lower partition 122 through the guide structure 13, thereby reducing the difficulty of operation and improving the assembly efficiency.

[0086] The water pump 24 can also be installed on the chassis 11, and / or the water pump 24 can also be installed on the carrier connected to the partition 12. After the water pump 24 and the second heat exchanger 22 are installed separately, they are then assembled, thereby simplifying the assembly process and improving the assembly efficiency.

[0087] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the second space 1b is also provided with an electrical control component 3, which is higher than the second heat exchanger 22 and installed on the upper partition 121.

[0088] The electrical control assembly 3 is arranged above the second heat exchanger 22. The electrical control assembly 3 is installed with the upper partition 121. By setting the partition 12 as an upper partition 121 and a lower partition 122 that are connected vertically, it is only necessary to assemble the electrical control assembly 3 with the upper partition 121, instead of installing the electrical control assembly 3 with the entire partition 12. Compared with the entire partition, the upper partition 121 is smaller in size and volume, making it easier to operate, thereby reducing the difficulty of operation and improving assembly efficiency.

[0089] In some embodiments of this utility model, the electronic control component 3 and the upper partition 121 are positioned by the positioning structure 14 and fixedly connected by the second fastener.

[0090] The electronic control component 3 is positioned and then fixedly connected to the upper partition plate 121, which can improve the assembly efficiency of the electronic control component 3.

[0091] In some embodiments of this utility model, such as Figure 1 , Figure 6 and Figure 7 As shown, the electronic control assembly 3 includes an electronic control box 31, which includes a first box body 311 and a second box body 312. At least a portion of the first box body 311 is located in the first space 1a and has a ventilation opening 3110. The second box body 312 is located in the second space 1b and is assembled and connected to the first box body 311. The second box body 312 is positioned with the upper partition 121 by a positioning structure 14 and is fixedly connected by a second fastener.

[0092] The electronic control assembly 3 includes an electronic control box 31, which is used to install and arrange circuit boards and other components. These electrical components generate heat when working and have heat dissipation requirements. Therefore, placing at least a portion of the first box body 311 of the electronic control box 31 in the first space 1a and forming a vent 3110 is beneficial for the electronic control box 31 to dissipate heat to the first space 1a, which can improve the working stability of the electronic control assembly 3.

[0093] The second box 312 is located within the second space 1b and is assembled and connected to the first box 311. The second box 312 is positioned and fixedly connected to the upper partition 121 by the positioning structure 14 and by the second fastener. The assembly of the second box 312 and the upper partition 121 is stable and the assembly position is accurate. After the first box 311 and the second box 312 are assembled, the electrical control box 31 is installed on the upper partition 121 by connecting the second box 312 to the upper partition 121. In this way, only the second box 312 needs to be connected to the upper partition 121, which simplifies the assembly process and improves assembly efficiency.

[0094] In some embodiments of this utility model, such as Figure 6 As shown, the width direction Z of the partition 12 is perpendicular to the thickness direction X and the vertical direction Y of the partition 12. The electronic control component 3 and the upper partition 121 are positioned by the positioning structure 14 to prevent relative movement between the electronic control component 3 and the upper partition 121 in the three directions of the width direction Z, the thickness direction X and the vertical direction Y of the partition 12.

[0095] The positioning of the electronic control component 3 relative to the upper partition 121 restricts the relative movement of the electronic control component 3 relative to the upper partition 121 in three directions: the width direction Z, the thickness direction X, and the vertical direction Y of the partition 12. Specifically, the width direction Z of the partition 12 is perpendicular to both the thickness direction X and the vertical direction Y, and the thickness direction X is perpendicular to the vertical direction Y. Therefore, the electronic control component 3 is limited in all three relatively perpendicular directions, improving its installation stability.

[0096] In some embodiments of this utility model, such as Figure 8 As shown, the upper partition 121 is connected to the side plate 211 of the first heat exchanger 21.

[0097] The upper partition 121 divides the space above the chassis 11 into a first space 1a and a second space 1b. The first heat exchanger 21 is set in the first space 1a. The upper partition 121 is connected to the side plate 211 of the first heat exchanger 21. The arrangement of the first heat exchanger 21 is compact, which can improve the installation stability of the first heat exchanger 21.

[0098] In some embodiments of this utility model, such as Figure 6 and Figure 8As shown, the upper partition 121 includes a partition portion 1211 spaced between the first space 1a and the second space 1b, and a first folded edge portion 1212 connected to one side of the width of the partition portion 1211 and extending toward the second space 1b. The electrical control assembly 3 includes a first mounting plate 32 corresponding to the first folded edge portion 1212. The first mounting plate 32 and the side plate 211 of the first heat exchanger 21 are located on both sides of the thickness of the first folded edge portion 1212 and are both connected to the first folded edge portion 1212.

[0099] The upper partition 121 includes a partition portion 1211, which is used to divide the space above the chassis 11 into a first space 1a and a second space 1b. A first folded edge portion 1212 is connected to one side of the partition portion 1211 in the width direction. The first folded edge portion 1212 is bent and connected to the partition portion 1211, which can increase the structural complexity of the partition 12 and improve the structural stability of the partition 12. The first folded edge portion 1212 is used to connect with other structures, which can improve the arrangement stability of the partition 12.

[0100] The first folded edge 1212 extends toward the second space 1b. The electrical control assembly 3 includes a first mounting plate 32 disposed on the first folded edge 1212. The electrical control assembly 3 is disposed within the second space 1b, so the first mounting plate 32 is located on the side of the first folded edge 1212 closer to the second space 1b in the thickness direction. The first heat exchanger 21 is disposed within the first space 1a, and the side plate 211 of the first heat exchanger 21 is located on the side of the first folded edge 1212 away from the second space 1b in the thickness direction. The first mounting plate 32 and the side plate 211 of the first heat exchanger 21 sandwich the first folded edge 1212. The first folded edge 1212 is connected to the side plate 211 of the first heat exchanger 21, and the first folded edge 1212 is also connected to the first mounting plate 32. By using the first folded edge 1212 to connect simultaneously with the heat exchanger and the electrical control assembly 3, the connection is reliable and stable, making the overall structure of the air source heat pump 100 stable and compact.

[0101] For example, the first folded edge portion 1212 is connected to the side plate 211 of the first heat exchanger 21 and the first mounting plate 32 at different points along the width direction of the partition portion 1211; or, for example again, fasteners pass through the first mounting plate 32, the first folded edge portion 1212 and the side plate 211 of the first heat exchanger 21 in sequence to connect the first mounting plate 32, the first folded edge portion 1212 and the first heat exchanger 21 together.

[0102] In some embodiments of this application, combined with Figure 6The upper partition 121 may also include a second folded edge 1213 connected to the other side of the width of the partition portion 1211. The second folded edge 1213 is a self-bent structure, including at least a portion extending along the thickness direction X of the partition 12 and at least a portion extending along the width direction Z of the partition 12. The electronic control assembly 3 includes a second mounting plate 33 corresponding to and close to the second folded edge 1213. The second mounting plate 33 is in surface contact with at least a portion of the second folded edge 1213, which can improve the installation stability of the electronic control assembly 3.

[0103] In some embodiments of this utility model, such as Figure 6 As shown, the positioning structure 14 may include a first positioning structure 141. The first folded edge 1212 and the first mounting plate 32 are positioned and engaged by the first positioning structure 141. The first folded edge 1212 is provided with a locking block 1411 protruding towards the second space 1b. The first mounting plate 32 is provided with a locking hole 1412. The locking block 1411 and the locking hole 1412 are engaged to form the first positioning structure 141, so as to restrict the relative movement of the electronic control component 3 relative to the upper partition 121 in the vertical direction Y and the thickness direction X of the partition 12.

[0104] like Figure 6 As shown, the positioning structure 14 may further include a first hook 142 and a second hook 143 disposed on the second mounting plate 33, the first hook 142 and the second hook 143 being hung from top to bottom on the top of the second folded edge portion 1213. Exemplarily, the first hook 142 is bent toward the thickness direction X of the partition 12, and the second hook 143 is bent along the width direction Z of the partition 12. The first hook 142 and the second hook 143 respectively cooperate with the top of the upper partition 121 to limit the relative movement of the electronic control assembly 3 relative to the upper partition 121 in the width direction Z and the thickness direction X of the partition 12.

[0105] Therefore, the electronic control component 3 is limited relative to the upper partition 121 in three directions: the width direction Z, the thickness direction X, and the vertical direction Y of the partition 12, which can improve the installation stability of the electronic control component 3.

[0106] In some embodiments of this utility model, such as Figure 2 As shown, the second space 1b is also provided with a bracket 15, which is located between the compressor 23 and the second heat exchanger 22. The bracket 15 is connected to the lower end of the upper partition 121 or to the upper end of the lower partition 122. The compressor 23 is fixedly installed on the bracket 15.

[0107] The bracket 15 is located at the junction P of the upper partition 121 and the lower partition 122. The bracket 15 can be connected to the lower end of the upper partition 121 and the upper end of the lower partition 122. The bracket 15 is used to support and install the compressor 23, which is fixedly installed on the bracket 15. Furthermore, the bracket 15 can separate the compressor 23 from the second heat exchanger 22, preventing the weight of the compressor 23 from compressing the second heat exchanger 22 and improving the operational stability of the second heat exchanger 22.

[0108] In some embodiments of this utility model, such as Figure 7 and Figure 9 As shown, the upper end of the lower partition 122 and the lower end of the upper partition 121 at least partially overlap and seal each other. The overlapping seal can be achieved by stacking two vertical plates horizontally or two horizontal plates vertically; there is no limitation on this.

[0109] The upper partition 121 and the lower partition 122 are assembled and connected along the vertical direction Y. The first space 1a and the second space 1b separated by the partition 12 have different functions. The first heat exchanger 21 is installed in the first space 1a to exchange heat with the air, while the second heat exchanger 22 installed in the second space 1b is used for heat exchange in the refrigerant flow path and the water flow path. Therefore, by at least partially overlapping and sealing the upper and lower ends of the lower partition 122, the sealing performance between the first space 1a and the second space 1b can be improved, reducing air leakage from the first space 1a into the second space 1b and improving the thermal impact on the second heat exchanger 22. Furthermore, it can also reduce the possibility of rainwater, dust, and other impurities from the outside entering the second space 1b through the gap between the upper partition 121 and the lower partition 122 via the first space 1a, which is beneficial to improving the operational stability of the second heat exchanger 22.

[0110] In some embodiments of this utility model, such as Figure 9 As shown, the upper end of the lower partition 122 is bent in the horizontal direction to form a support plate 1221, and the lower end of the upper partition 121 is bent in the horizontal direction to form an abutment plate 1214. The support plate 1221 supports the abutment plate 1214 and is in close contact with the abutment plate 1214.

[0111] The upper partition 121 and the lower partition 122 are arranged and assembled in the vertical direction Y. Therefore, the upper end of the lower partition 122 is bent in the horizontal direction to form a support plate 1221, which cooperates with the abutment plate 1214 formed by bending the lower end of the upper partition 121 in the horizontal direction. The support plate 1221 supports the abutment plate 1214 from below and is in close contact with the abutment plate 1214. This not only improves the connection stability between the upper partition 121 and the lower partition 122, but also improves the sealing performance between the upper partition 121 and the lower partition 122. The upper partition 121 and the lower partition 122 are in close contact and sealed, improving the sealing and reducing interference to the second heat exchanger 22.

[0112] In some embodiments of this utility model, such as Figure 9 As shown, the lower partition 122 includes a lower partition body 1222, a support plate 1221 connected to the upper end of the lower partition body 1222 and extending toward the direction close to the second space 1b, an abutment plate 1214 extending toward the direction away from the second space 1b, and a connecting plate 1215 extending downward at the end of the abutment plate 1214 away from the second space 1b. The connecting plate 1215 is located on the side of the lower partition body 1222 away from the second space 1b, and a third fastener passes through the connecting plate 1215 and the lower partition body 1222 in a horizontal direction to fix the upper partition 121 and the lower partition 122 together.

[0113] The support plate 1221 is connected to the upper end of the lower partition body 1222 and extends towards the direction close to the second space 1b. The abutment plate 1214 extends away from the second space 1b. The end of the abutment plate 1214 away from the second space 1b can directly extend downward to the connecting plate 1215 without having to avoid the support plate 1221. The connecting plate 1215 is located on the side of the lower partition body 1222 away from the second space 1b. The third fastener passes through the connecting plate 1215 and the lower partition body 1222 in the horizontal direction. The upper partition 121 and the lower partition 122 are supported in the vertical direction Y and fixedly connected in the horizontal direction by the third fastener, which can improve the connection stability of the upper partition 121 and the lower partition 122.

[0114] In some embodiments of this utility model, such as Figure 10 As shown, the upper end of the lower partition 122 is hooked and limited to the lower end of the upper partition 121.

[0115] The lower partition 122 and the upper partition 121 are engaged by a hook-and-loop locking mechanism, which allows for pre-positioning of the upper partition 121 and the lower partition 122 during assembly, thereby improving the assembly stability of the upper partition 121 and the lower partition 122. The hook-and-loop locking mechanism is simple to operate and easy to use, and the hook-and-loop locking mechanism also prevents the upper partition 121 from tipping over relative to the lower partition 122, further enhancing the pre-positioning stability of the upper partition 121 and the lower partition 122.

[0116] In some embodiments of this utility model, such as Figure 10 As shown, the support plate 1221 has a limiting hole 12211 that extends through the upper partition 121 in the vertical direction Y on the part of the support plate 1221 that is close to the second space 1b. The lower end of the upper partition 121 is provided with a limiting hook 1216. The limiting hook 1216 is hooked and engaged with the limiting hole 12211. The hook part of the limiting hook 1216 extends into the lower partition 122, and at least a portion of the hook part of the limiting hook 1216 is directly opposite the solid part of the support plate 1221 in the vertical direction Y.

[0117] A limiting hole 12211 is provided on the lower partition 122, and a limiting hook 1216 is provided at the lower end of the upper partition 121. The hook part of the limiting hook 1216 extends into the lower partition 122. At least part of the hook part of the limiting hook 1216 is directly opposite to the non-limiting hole 12211 of the support plate 1221 in the vertical direction Y. Therefore, the hook part of the limiting hook 1216 can be limited and engaged with the support plate 1221 in the vertical direction Y, thereby pre-positioning the assembly of the upper partition 121 and the lower partition 122 to improve the assembly stability of the upper partition 121 and the lower partition 122.

[0118] In some embodiments of this utility model, such as Figure 10 As shown, the extension length L2 of the limiting hole 12211 is greater than or equal to the length L1 of the hook portion of the limiting hook 1216 in the extension direction of the limiting hole 12211, so that the hook portion of the limiting hook 1216 can pass smoothly through the limiting hole 12211.

[0119] In some embodiments of this utility model, such as Figure 11 , Figure 12 and Figure 13 As shown, the housing assembly 1 also includes a housing side plate 16, which is located on the side of the second space 1b away from the first space 1a. The housing side plate 16 helps to define the second space 1b. The housing side plate 16 includes a first side plate 161 and a maintenance plate 162. The first side plate 161 has a maintenance port 161a. The upper end of the maintenance port 161a is opposite to or lower than the lower part of the compressor 23. The maintenance plate 162 is detachably connected to or movably connected to the first side plate 161 to open and close the maintenance port 161a.

[0120] The shell side panel 16 includes a first side panel 161 with an access port 161a communicating with the second space 1b. A maintenance plate 162 is detachably or movably connected to the first side panel 161. When the access port 161a is opened, it exposes the lower space of the compressor 23, allowing maintenance of the components below the compressor 23 without removing the entire shell side panel 16 from the shell assembly 1, thus reducing operational difficulty. After maintenance, closing the access port 162 improves the sealing and tidiness of the second space 1b. The operation of opening and closing the access port 161a is simple, improving maintenance efficiency.

[0121] For example, the second space 1b is further provided with a water pump 24, which is lower than the compressor 23 and connected to the water flow path. The water pump 24 can drive the liquid flow in the water flow path. The water pump 24 is located in the second space 1b and is positioned lower than the compressor 23. For example, after the inspection plate 162 opens the inspection port 161a, the water pump 24 can be maintained. For example, when the inspection port 161a is open, part of the water pump 24 is exposed, such as the connection with the second heat exchanger 22, allowing for leak-proof maintenance at the connection between the water pump 24 and the second heat exchanger 22. For another example, when the inspection port 161a is open, the entire water pump 24 is exposed through the inspection port 161a. For yet another example, after the inspection plate 162 opens the maintenance port, the second heat exchanger 22 below the compressor 23 can be maintained.

[0122] In some embodiments of this utility model, the water pump 24 is located on the side of the second heat exchanger 22 near the access port 161a. When the access port 161a is open, the water pump 24 is exposed, so that the water pump 24 can be fully exposed and maintained. Moreover, not only can the water pump 24 be repaired from the access port 161a, but in some examples, when the access port 161a is large enough, the water pump 24 can also be removed from the access port 161a for repair or replacement.

[0123] In some embodiments of this utility model, such as Figure 11 and Figure 12 As shown, the shell side plate 16 also includes a second side plate 163. The first side plate 161 and the second side plate 163 are connected along the width direction Z of the partition 12. An inspection port 161a is defined between the first side plate 161 and the second side plate 163. The lower end of the second side plate 163 is spaced apart from the chassis 11. The shell side plate 16 also includes a water outlet valve plate 164 connected to the second side plate 163 and below the inspection plate 162. The inspection plate 162 and the water outlet valve plate 164 are connected by a fourth fastener. The inspection plate 162 is hooked and positioned to the first side plate 161 and is fixedly connected by a fifth fastener. Thus, the shell side plate 16 has a simple structure and is easy to process, assemble, and disassemble.

[0124] The lower end of the shell side plate 16 is connected to the chassis 11 to improve the structural stability of the shell assembly 1. The lower end of the second side plate 163 is spaced apart from the chassis 11 in the vertical direction Y. The lower end of the second side plate 163 is connected to the outlet valve plate 164, which in turn is connected to the chassis 11. The outlet valve plate 164 includes a first valve plate 1641 located directly below the second side plate 163 and a second valve plate 1642 located directly below the inspection plate 162. The lower end of the inspection plate 162, installed at the inspection port 161a, is also spaced apart from the chassis 11 in the vertical direction Y. The lower end of the inspection plate 162 is connected to the second valve plate 1642, which in turn is connected to the chassis 11.

[0125] The inspection plate 162 and the first side plate 161 are pre-positioned by hooks, and then the inspection plate 162 and the first side plate 161 are fixedly connected by fasteners. The connection method of positioning and then fastening the inspection plate 162 and the first side plate 161 can improve the assembly efficiency of the inspection plate 162.

[0126] The inspection plate 162 is also fixedly connected to the outlet valve plate 164, which can improve the arrangement stability of the inspection plate 162 when closing the inspection port 161a. The inspection plate 162 has the need to open and close the inspection port 161a. Therefore, the inspection plate 162 is at least partially located on the side of the outlet valve plate 164 away from the second space 1b. The inspection plate 162 can be directly disassembled to open the inspection port 161a without disassembling the outlet valve plate 164.

[0127] In some embodiments of this utility model, one end of the inspection plate 162 in the width direction Z of the partition 12 is hooked and positioned with the first side plate 161. The inspection plate 162 and the first side plate 161 are fixedly connected by at least three fasteners. At least two fasteners are spaced apart in the vertical direction Y, and at least two fasteners are spaced apart in the width direction Z of the partition 12, thereby improving the connection stability of the inspection plate 162.

[0128] In some embodiments of this utility model, the inspection plate 162 and the outlet valve plate 164 are fixedly connected by at least two fasteners, and the at least two fasteners are spaced apart along the width direction Z of the partition plate 12; the inspection plate 162 is fixedly connected to the first valve plate 1641 by at least one fastener, and the inspection plate 162 is fixedly connected to the second valve plate 1642 by at least one fastener.

[0129] In some embodiments of this utility model, when assembling the shell side plate 16, the first side plate 161 is first fixedly installed on the side of the second space 1b away from the first space 1a, and the first side plate 161 serves as a reference plate; then the inspection plate 162 and the water outlet valve plate 164 are fixedly connected as a whole by fasteners; then the inspection plate 162 and the water outlet valve plate 164, which are as a whole, are connected together to the first side plate 161, wherein the inspection plate 162 of the inspection plate 162 and the water outlet valve plate 164, which are as a whole, are fixedly connected to the first side plate 161 after being positioned; finally, the second side plate 163 is fixedly connected, wherein the second side plate 163 is connected to the water outlet valve plate 164.

[0130] When maintenance is required, simply disconnect the inspection plate 162 from the outlet valve plate 164 and disconnect the inspection plate 162 from the first side plate 161 to open the inspection port 161a, thereby allowing maintenance of the components located below the compressor 23 in the second space 1b.

[0131] In some embodiments of this utility model, the inspection cover has an air vent to allow air to circulate and dissipate heat.

[0132] In some embodiments of this utility model, the water outlet valve plate 164 includes a first valve plate 1641 and a second valve plate 1642. The first valve plate 1641 is provided with a water outlet, and the second valve plate 1642 and the inspection plate 162 together form a water inlet. The water outlet and the water inlet are available for pipelines connected to the water flow path to pass through.

[0133] In some embodiments of this utility model, such as Figure 13 As shown, the air source heat pump 100 also includes a terminal mounting plate 4, which is used to set wiring terminals. The terminal mounting plate 4 is set in the second space 1b and is set higher than the second heat exchanger 22. The housing assembly 1 also includes a housing side plate 16, which is located on the side of the second space 1b away from the first space 1a. The housing side plate 16 participates in defining the second space 1b. The housing side plate 16 includes a first side plate 161. The terminal mounting plate 4 is connected to the first side plate 161. The first side plate 161 has a clearance opening 1611, which is at least opposite to the position of the terminal mounting plate 4 where the wiring terminals are set.

[0134] Terminal mounting plate 4 is used to set wiring terminals, which can be used for wire harness connection or for limiting the connection of wire harness terminals.

[0135] The shell side plate 16 includes a first side plate 161, on which a clearance opening 1611 is provided. The clearance opening 1611 communicates with the second space 1b, and the clearance opening 1611 is at least opposite to the position where the terminal mounting plate 4 is set with the wiring terminals. This allows the wiring terminals to be exposed in the second space 1b, so that wiring or maintenance can be performed directly at the wiring terminals without having to remove the entire shell side plate 16 from the shell assembly 1, thus reducing the difficulty of operation.

[0136] In some embodiments of this utility model, the housing assembly 1 further includes an outer cover plate 165, which is detachably or movably connected to the first side plate 161 to open and close the clearance opening 1611. When wiring or maintenance of the wiring terminals is required, the clearance opening 1611 can be opened through the outer cover plate 165 without having to remove the entire housing side plate 16 from the housing assembly 1. After wiring or maintenance is completed, the outer cover plate 165 can be directly connected to the first side plate 161 to protect the wiring terminals and reduce external contamination from contacting the wiring terminals.

[0137] In some embodiments of this utility model, such as Figure 13 and Figure 14As shown, the terminal mounting plate 4 has a mounting plate 41 at its bottom end, and a connecting structure 1612 at the lower edge of the clearance opening 1611. The connecting structure 1612 is positioned and engaged with the mounting plate 41 to restrict the terminal mounting plate 4 from moving relative to the first side plate 161 in the vertical direction Y, the thickness direction X of the partition 12, and the width direction Z of the partition 12; and / or, the connecting structure 1612 and the mounting plate 41 are fixedly connected by a sixth fastener.

[0138] The terminal mounting plate 4 is connected to the shell side plate 16 via the bottom mounting plate 41. A connecting structure 1612 is provided at the lower edge of the clearance opening 1611. The connecting structure 1612 is positioned and / or fixedly connected to the terminal mounting plate 4, thereby improving the ease of installation of the terminal mounting plate 4.

[0139] For example, the terminal mounting plate 4 is positioned and engaged with the connecting structure 1612 before being fixedly connected by fasteners. This improves the assembly efficiency of the terminal mounting plate 4. Furthermore, the connection method of positioning and then fixing via the connecting structure 1612 eliminates the need for manual positioning by the installer compared to the method of fixing only via fasteners. It also improves the problem of misalignment of the fixing holes after the terminal mounting plate 4 and the shell side plate 16 are engaged, thereby reducing the difficulty of operation and improving assembly efficiency.

[0140] In some embodiments of this utility model, such as Figures 13-16 As shown, the connecting structure 1612 includes a fixing plate 16121, a bending plate 1613, and a protrusion 16122. The fixing plate 16121 is connected to the lower edge of the clearance opening 1611 and extends upward at an incline towards the partition 12. The bending plate 1613 is connected to the center of the upper edge of the fixing plate 16121 and extends downward at an incline towards the partition 12. The protrusion 16122 is located on the side of the bending plate 1613 near the partition 12. The mounting plate 41 extends downward at an incline towards the clearance opening 1611. The mounting plate 41 has a clearance notch 411 at its lower center, which extends through the lower end of the mounting plate 41. The lower part of the mounting plate 41 extends to the bottom side of the fixing plate 16121 and is fixedly connected to the fixing plate 16121 by a sixth fastener. The bent plate 1613 extends downward from the clearance notch 411 towards the mounting plate 41 and is limited along the width direction Z of the partition plate 12 to the portions of the mounting plate 41 located on both sides of the clearance notch 411. The protrusion 16122 supports the bottom surface of the mounting plate 41 above the clearance notch 411. Thus, the structure is simple, easy to position and connect, and improves assembly efficiency.

[0141] like Figure 13As shown, the mounting plate 41 extends obliquely from bottom to top along the thickness direction X of the partition 12 close to the partition 12. The connecting structure 1612 includes a fixing plate 16121. The fixing plate 16121 is connected to the lower edge of the clearance opening 1611 and extends obliquely from bottom to top along the thickness direction X of the partition 12 close to the partition 12. The fixing plate 16121 is in surface contact with the mounting plate 41 and is fixedly connected by fasteners.

[0142] The mounting plate 41 and the fixing plate 16121 are inclined in the same direction. The fixing plate 16121 and the mounting plate 41 can fit together to increase the contact area and improve the stability of the fastener fixing connection. The fixing plate 16121 serves to connect and fix the terminal mounting plate 4 and the first side plate 161.

[0143] like Figure 14 As shown, the connecting structure 1612 also includes a protrusion 16122. The protrusion 16122 abuts against the side of the partition 12 of the mounting plate 41 in the thickness direction X, close to the partition 12, to limit the mounting plate 41. The protrusion 16122 and the fixing plate 16121 together play the role of positioning the mounting plate 41. The fixing plate 16121 is located on the side of the partition 12 of the mounting plate 41 in the thickness direction X, away from the partition 12. The protrusion 16122 is located on the side of the partition 12 of the mounting plate 41 in the thickness direction X, close to the partition 12. The mounting plate 41 extends obliquely from bottom to top along the thickness direction X of the partition 12, close to the partition 12. Therefore, the center of gravity of the terminal mounting plate 4 is closer to the side of the partition 12. When the mounting plate 41 is moved to the installation position, the mounting plate 41 will naturally abut against the protrusion 16122 under the action of gravity. The protrusion 16122 can support the mounting plate 41. The fixing plate 16121 is located on the other side of the mounting plate 41, and the protrusion 16122 supports the mounting plate. The protrusion 16122 and the fixing plate 16121 together clamp the mounting plate 41 to position the terminal mounting plate 4.

[0144] like Figure 15 and Figure 16 As shown, the protrusion 16122 is connected to the upper edge of the fixing plate 16121 via the bending plate 1613. The bending plate 1613 extends obliquely from top to bottom along the thickness direction X of the partition 12 close to the partition 12. The protrusion 16122 protrudes from the upper side of the bending plate 1613. The upper end of the bending plate 1613 is bent and connected to the upper edge of the fixing plate 16121.

[0145] Compared to extending the protrusion directly upward on the first side, connecting the upper edge of the bending plate 1613 to the fixing plate 16121 and protruding the protrusion 16122 on the bending plate 1613 can not only improve the pressure bearing capacity of the protrusion 16122 and improve the installation stability of the terminal mounting plate 4, but also reduce the volume of the protrusion 16122, which is beneficial to reducing manufacturing costs.

[0146] like Figure 17 As shown, a clearance notch 411 is provided in the middle of the mounting plate 41 along the thickness direction of the mounting plate 41. The clearance notch 411 extends to the lower end of the mounting plate 41. The bent plate 1613 extends into the clearance notch 411. The protrusion 16122 can abut against the plate portion above the clearance notch 411. The plate portions of the mounting plate 41 on both sides of the clearance notch 411 along the length direction are in close contact with and fixedly connected to the fixing plate 16121.

[0147] The bent plate 1613 is connected to the fixed plate 16121. Therefore, the lower end of the mounting plate 41 is provided with a clearance notch 411. The clearance notch 411 allows the mounting plate 41 to avoid the bent plate 1613 for assembly. The plate portion of the clearance notch 411 along the width direction Z of the partition 12 is in close contact with and fixedly connected to the surface of the fixed plate 16121. The width direction Z of the partition 12 is perpendicular to the thickness direction X and the vertical direction Y of the partition 12. The side of the plate portion above the clearance notch 411 that is close to the partition 12 abuts against the protrusion 16122.

[0148] It is worth noting that the fixing plate 16121 in the connecting structure 1612 is mainly used to fix the mounting plate 41. After the mounting plate 41 and the fixing plate 16121 are fixedly installed, the protrusion 16122 can continue to abut and support the mounting plate 41, for example; and for example, as Figure 14 As shown, the protrusion 16122 can also be separated from the mounting plate 41, thereby reducing wear on the mounting plate 41. Furthermore, the gap between the protrusion 16122 and the mounting plate 41 is relatively large, which is beneficial for the installation of the terminal mounting plate 4.

[0149] In some embodiments of this utility model, the gap between the bending plate 1613 and the clearance notch 411 is greater than 1 mm.

[0150] The gap between the bending plate 1613 and the clearance notch 411 refers to the gap between the bending plate 1613 and the clearance notch 411 in the vertical direction Y and the gap between the bending plate 1613 and the clearance notch 411 in the width direction Z of the partition 12.

[0151] If the gap between the bending plate 1613 and the clearance notch 411 is too small, it will be difficult for the mounting plate 41 to avoid the bending plate 1613 during assembly. Therefore, the opening area of ​​the clearance notch 411 is increased so that the gap between the bending plate 1613 and the clearance notch 411 is greater than 1mm. This can reduce the interference of the bending plate 1613 on the mounting plate 41 during assembly and improve assembly efficiency.

[0152] For example, the gap between the bent plate 1613 and the clearance notch 411 is 1.2mm, 1.5mm, 2mm, 2.5mm, 3mm, etc.

[0153] In some embodiments of this utility model, such as Figure 16 As shown, the included angle α between the bending plate 1613 and the fixing plate 16121 is less than or equal to 150°.

[0154] It is worth noting that the clearance opening 1611 can at least be used for wiring of the terminal block. Therefore, the opening size of the clearance opening 1611 can be smaller than the projected area of ​​the terminal mounting plate 4, which facilitates processing and reduces manufacturing costs.

[0155] The clearance 1611 is relatively small, and the terminal mounting plate 4 can be installed from the side of the first side plate 161 near the partition 12. However, when the angle α between the bent plate 1613 and the fixing plate 16121 is too large, the lower end of the bent plate 1613 will be too high in the vertical direction Y. This will increase the stroke required to move the terminal mounting plate 4 from bottom to top around the bent plate 1613 into the clamping position of the protrusion 16122 and the fixing plate 16121.

[0156] Therefore, by setting the included angle α between the bending plate 1613 and the fixing plate 16121 to less than or equal to 150°, the travel distance of the terminal mounting plate 4 when it is installed around the bending plate 1613 can be reduced, thereby improving the assembly efficiency of the terminal mounting part.

[0157] For example, the included angle α between the bending plate 1613 and the fixing plate 16121 can be 90°, 110°, 120°, 135°, 150°, etc.
