Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0038] In the present application, the terms "installed", "set", "provided with", "connected", and "linked" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral structure; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, or there may be internal communication between two devices, components, or parts. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0039] In addition, terms such as "first", "second", etc. are mainly used to distinguish different devices, components or constituent parts (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, components or constituent parts. Unless otherwise specified, the meaning of "a plurality of" is two or more.

[0040] The technical solution of the present application will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0041] Please refer to Figure 1 and Figure 2 , the present application provides a heat pump unit 1, including a chassis 11 having a frame body 111 and a heat exchange assembly 12. The frame body 111 encloses a hollow area 112. The heat exchange assembly 12 includes a support member 121 and a heat exchanger 122. The support member 121 is detachably connected to the frame body 111, and the heat exchanger 122 is connected to the support member 121. Among them, the heat exchange assembly 12 is configured to be taken out through the hollow area 112 when the support member 121 is detached from the frame body 111.

[0042] In the embodiment of the present application, the heat pump unit 1 may be a part of an air conditioner or other devices that require heat exchange, which is not limited herein.

[0043] Among them, the chassis 11 of the heat pump unit 1 has a load-bearing capacity. The shape of the chassis 11 may be square or other shapes, which is not limited herein. The chassis 11, as a component of the load-bearing frame of the heat pump unit 1, is used to enclose the installation space of the heat pump unit 1, and the heat exchange assembly 12 is installed in the installation space of the heat pump unit 1.

[0044] Please refer to Figure 1 and Figure 3 , exemplarily, the frame body 111 of the chassis 11 is used to enclose the hollow area 112 that communicates with the installation space of the heat pump unit 1, and the heat exchange assembly 12 is arranged in the installation space of the heat pump unit 1. It should be noted that in the projection direction perpendicular to the chassis 11, the heat exchange assembly 12 basically entirely falls within the hollow area 112, that is, in the projection direction perpendicular to the chassis 11, the projection area of the heat exchange assembly 12 is less than or equal to the area of the hollow area 112.

[0045] In one example, in the projection direction perpendicular to the chassis 11, the projected area of the heat exchange component 12 is less than or equal to the area of the hollowed-out region 112, and in the projection direction perpendicular to the chassis 11, the projection of the heat exchange component 12 entirely falls within the hollowed-out region 112. When the heat exchanger 122 of the heat exchange component 12 needs to be repaired or replaced, during the process of disassembling the heat exchange component 12, only the support member 121 of the heat exchange component 12 needs to be detached from the frame body 111, and then the heat exchange component 12 can be taken out through the hollowed-out region 112. After the heat exchanger 122 of the heat exchange component 12 is repaired or replaced, during the process of installing the heat exchange component 12, only the heat exchange component 12 needs to be placed into the installation space of the heat pump unit 1 through the hollowed-out region 112, and then the support member 121 is installed on the frame body 111, thereby completing the installation of the heat exchange component 12.

[0046] In another example, in the projection direction perpendicular to the chassis 11, the projected area of the heat exchange component 12 can be less than or equal to the area of the hollowed-out region 112, but in the projection direction perpendicular to the chassis 11, most of the projection of the heat exchange component 12 falls within the hollowed-out region 112. In other words, the projections of the heat exchanger 122 and the support member 121 of the heat exchange component 12 entirely fall within the hollowed-out region 112, but the heat exchange component 12 can also have components connected to the support member 121 whose projections do not fall within the hollowed-out region 112.

[0047] In this example, when the heat exchanger 122 of the heat exchange component 12 needs to be repaired or replaced, during the process of disassembling the heat exchange component 12, first detach the support member 121 of the heat exchange component 12 from the frame body 111, and after the support member 121 is detached from the frame body 111, the support member 121 can be slightly tilted or elastically bent, so that the projections of the components of the heat exchange component 12 that do not fall within the hollowed-out region 112 can fall within the hollowed-out region 112 after the support member 121 is tilted or elastically bent, and thus the heat exchange component 12 can be taken out through the hollowed-out region 112. Similar operations are performed when installing the heat exchange component 12 after the heat exchanger 122 of the heat exchange component 12 is repaired or replaced, which will not be elaborated here.

[0048] Alternatively, components of the heat exchange assembly 12 whose projections do not fall within the hollowed-out area 112 can be detachably connected to the support member 121. When the heat exchanger 122 of the heat exchange assembly 12 needs to be repaired or replaced, during the process of disassembling the heat exchange assembly 12, the components of the heat exchange assembly 12 whose projections do not fall within the hollowed-out area 112 can be detached from the support member 121 first, and then the support member 121 can be detached from the frame body 111, so that the heat exchanger 122 and the support member 121 can be taken out through the hollowed-out area 112 first, and then the components of the heat exchange assembly 12 whose projections do not fall within the hollowed-out area 112 can be taken out through the hollowed-out area 112. Of course, it is also possible to first detach the support member 121 from the frame body 111 and then detach the components of the heat exchange assembly 12 whose projections do not fall within the hollowed-out area 112 from the support member 121, which will not be elaborated here. Similarly, during the installation of the heat exchange assembly 12 after the heat exchanger 122 of the heat exchange assembly 12 is repaired or replaced, similar operations are carried out, which will not be elaborated here.

[0049] In addition, it can be understood that the heat exchanger 122 has a water inlet 1221, a water outlet 1222, a fluorine circuit inlet and a fluorine circuit outlet, and when the heat pump unit 1 is in an assembled state, the water inlet 1221, the water outlet 1222, the fluorine circuit inlet and the fluorine circuit outlet are all connected to other components installed in the installation space of the heat pump unit 1 to form a connected state. When it is necessary to disassemble the heat exchange assembly 12, the staff can first disassemble the water inlet 1221, the water outlet 1222, the fluorine circuit inlet and the fluorine circuit outlet into a non-connected state through the hollowed-out area 112, and then detach the support member 121 from the frame body 111 and take it out through the hollowed-out area 112.

[0050] In summary, for the heat pump unit 1 provided in the embodiment of the present application, compared with the prior art that requires disassembling the shell of the heat pump unit 1 and then disassembling the heat exchanger 122, by providing the hollowed-out area 112 on the chassis 11, the heat exchange assembly 12 can be taken out through the hollowed-out area 112 after the support member 121 of the heat exchange assembly 12 is detached from the frame body 111, and during the installation process of the heat exchange assembly 12, it can also be installed through the hollowed-out area 112, so that the heat exchange assembly 12 can be installed without disassembling the shell of the heat pump unit 1 during the disassembly and assembly process, thereby improving the efficiency of disassembling and assembling the heat exchange assembly 12, shortening the cycle of disassembling and assembling the heat exchange assembly 12, and reducing the difficulty of disassembling and assembling the heat exchange assembly 12.

[0051] Please refer to Figure 1 and Figure 4 , in some embodiments, the frame body 111 has a side surface 1111 for enclosing the hollowed-out area 112, and the support member 121 is detachably connected to the side surface 1111.

[0052] Among them, when the heat pump unit 1 is in a working state, the side surface 1111 of the frame body 111 can be substantially parallel to the vertical direction.

[0053] It can be understood that since the side surface 1111 of the frame body 111 encloses the hollow area 112, detachably connecting the support member 121 to the side surface 1111 can provide sufficient space for disassembling and assembling the support member 121, and at the same time reduce the difficulty of disassembling and assembling the support member 121.

[0054] In one example, in the projection direction perpendicular to the chassis 11, the projection area of the heat exchange assembly 12 is less than or equal to the area of the hollow area 112, and in the projection direction perpendicular to the chassis 11, the projection of the heat exchange assembly 12 entirely falls within the hollow area 112. When the heat exchanger 122 of the heat exchange assembly 12 needs to be repaired or replaced, during the process of disassembling the heat exchange assembly 12, only the support member 121 of the heat exchange assembly 12 needs to be detached from the side surface 1111 of the frame body 111, and then the heat exchange assembly 12 can be taken out through the hollow area 112. After the heat exchanger 122 of the heat exchange assembly 12 is repaired or replaced, during the process of installing the heat exchange assembly 12, only the heat exchange assembly 12 needs to be placed into the installation space of the heat pump unit 1 through the hollow area 112, and then the support member 121 is installed on the side surface 1111 of the frame body 111, thereby completing the installation of the heat exchange assembly 12.

[0055] In another example, in the projection direction perpendicular to the chassis 11, the projection area of the heat exchange assembly 12 can be less than or equal to the area of the hollow area 112, but in the projection direction perpendicular to the chassis 11, most of the projection of the heat exchange assembly 12 falls within the hollow area 112. In other words, the projections of the heat exchanger 122 and the support member 121 of the heat exchange assembly 12 all fall within the hollow area 112, but the heat exchange assembly 12 may also have components connected to the support member 121 whose projections do not fall within the hollow area 112.

[0056] In this example, when the heat exchanger 122 of the heat exchange assembly 12 needs to be repaired or replaced, during the process of disassembling the heat exchange assembly 12, first detach the support member 121 of the heat exchange assembly 12 from the side surface 1111 of the frame body 111, and after the support member 121 is detached from the side surface 1111 of the frame body 111, the support member 121 can be slightly tilted or elastically bent, so that the projections of the components of the heat exchange assembly 12 that do not fall within the hollow area 112 after the support member 121 is tilted or elastically bent can fall within the hollow area 112, thereby enabling the heat exchange assembly 12 to be taken out through the hollow area 112. Similar operations are performed during the installation of the heat exchange assembly 12 after the heat exchanger 122 of the heat exchange assembly 12 is repaired or replaced, which will not be elaborated here.

[0057] Alternatively, components of the heat exchange assembly 12 whose projections do not fall within the hollowed-out area 112 can be detachably connected to the support member 121. When the heat exchanger 122 of the heat exchange assembly 12 needs to be repaired or replaced, during the process of disassembling the heat exchange assembly 12, the components of the heat exchange assembly 12 whose projections do not fall within the hollowed-out area 112 can be detached from the support member 121 first, and then the support member 121 can be detached from the side surface 1111 of the frame body 111. Thus, the heat exchanger 122 and the support member 121 can be taken out through the hollowed-out area 112 first, and then the components of the heat exchange assembly 12 whose projections do not fall within the hollowed-out area 112 can be taken out through the hollowed-out area 112. Of course, it is also possible to first detach the support member 121 from the side surface 1111 of the frame body 111, and then detach the components of the heat exchange assembly 12 whose projections do not fall within the hollowed-out area 112 from the support member 121, which will not be elaborated here. Similarly, when installing the heat exchange assembly 12 after the heat exchanger 122 of the heat exchange assembly 12 is repaired or replaced, similar operations are performed, which will not be elaborated here.

[0058] In some other embodiments, the support member 121 can be detachably connected to the top surface 1112 of the frame body 111.

[0059] Please continue to refer to Figure 1 With Figure 4 , in some embodiments, the frame body 111 further has a top surface 1112 connected to the side surface 1111. The heat exchange assembly 12 further includes a limiting member 123. The limiting member 123 is connected to the support member 121 and the limiting member 123 overlaps on the top surface 1112 of the frame body 111.

[0060] It can be understood that when the heat pump unit 1 is in the working state, the side surface 1111 of the frame body 111 is substantially parallel to the vertical direction, and the top surface 1112 can also be substantially parallel to the horizontal direction. The support member 121 connected to the side surface 1111 can play a supporting role in carrying the heat exchanger 122.

[0061] In this embodiment, the limiting member 123 is connected to the support member 121 and overlaps on the top surface 1112 of the frame body 111, which can further improve the supporting effect of the support member 121 in carrying the heat exchanger 122. At the same time, when the support member 121 is accidentally separated from the side surface 1111, the limiting member 123 can continue to support the heat exchanger 122, thereby preventing the support member 121 and the heat exchanger 122 from falling off through the hollowed-out area 112.

[0062] Exemplarily, in the projection direction perpendicular to the chassis 11, the projected area of the heat exchange assembly 12 may be less than or equal to the area of the hollowed-out region 112. However, in the projection direction perpendicular to the chassis 11, most of the projection of the heat exchange assembly 12 falls within the hollowed-out region 112. In other words, the projections of the heat exchanger 122 and the support member 121 of the heat exchange assembly 12 all fall within the hollowed-out region 112. However, since the limiting member 123 overlaps the top surface 1112 of the frame body 111, at least part of the projection of the limiting member 123 does not fall within the hollowed-out region 112.

[0063] Among them, the first plate body 1231 of the limiting member 123 may be fixedly connected to the support member 121. When the heat exchanger 122 of the heat exchange assembly 12 needs to be repaired or replaced, during the process of disassembling the heat exchange assembly 12, first detach the support member 121 of the heat exchange assembly 12 from the side surface 1111 of the frame body 111, and after the support member 121 is detached from the side surface 1111 of the frame body 111, the support member 121 can be slightly tilted or elastically bent, so that the projection of the limiting member 123 after the support member 121 is tilted or elastically bent can fall within the hollowed-out region 112, so that the heat exchange assembly 12 can be taken out through the hollowed-out region 112. Similar operations are performed when installing the heat exchange assembly 12 after the heat exchanger 122 of the heat exchange assembly 12 is repaired or replaced, which will not be elaborated here.

[0064] Alternatively, the limiting member 123 may be detachably connected to the support member 121. When the heat exchanger 122 of the heat exchange assembly 12 needs to be repaired or replaced, during the process of disassembling the heat exchange assembly 12, the limiting member 123 can be detached from the support member 121 first, and then the support member 121 can be detached from the side surface 1111 of the frame body 111, so that the heat exchanger 122 and the support member 121 can be taken out through the hollowed-out region 112 first, and then the limiting member 123 can be taken out through the hollowed-out region 112. Of course, the support member 121 can also be detached from the side surface 1111 of the frame body 111 first, and then the limiting member 123 can be detached from the support member 121, which will not be elaborated here. Similarly, similar operations are performed when installing the heat exchange assembly 12 after the heat exchanger 122 of the heat exchange assembly 12 is repaired or replaced, which will not be elaborated here.

[0065] In some other embodiments, the frame body 111 has a bottom surface connected to the side surface 1111, and the bottom surface is opposite to the top surface 1112, and the limiting member 123 can also be detachably connected to the bottom surface of the frame body 111.

[0066] Please refer to Figure 4 、 Figure 5 and Figure 6, in some more specific embodiments, the limiting member 123 includes a first plate body 1231 and a second plate body 1232. The first plate body 1231 is connected to the support member 121, the second plate body 1232 is connected to the first plate body 1231, and the second plate body 1232 overlaps the top surface 1112 of the frame body 111.

[0067] Wherein, both the first plate body 1231 and the second plate body 1232 can be rectangular or square, and of course can also be other shapes, which are not limited herein.

[0068] The first plate body 1231 is connected to the support member 121, and the end face of the first plate body 1231 is attached to the support member 121. The side surface 1111 of the second plate body 1232 is connected to the other end face of the first plate body 1231. The second plate body 1232 overlapping the top surface 1112 of the frame body 111 can further improve the supporting effect of the support member 121 for carrying the heat exchanger 122.

[0069] Exemplarily, in the projection direction perpendicular to the chassis 11, the projection area of the heat exchange assembly 12 can be less than or equal to the area of the hollowed-out area 112, but in the projection direction perpendicular to the chassis 11, most of the projection of the heat exchange assembly 12 falls within the hollowed-out area 112. In other words, the projections of the heat exchanger 122 and the support member 121 of the heat exchange assembly 12 all fall within the hollowed-out area 112. However, since the second plate body 1232 of the limiting member 123 overlaps the top surface 1112 of the frame body 111, at least part of the projection of the second plate body 1232 of the limiting member 123 does not fall within the hollowed-out area 112.

[0070] Wherein, the first plate body 1231 of the limiting member 123 can be fixedly connected to the support member 121. When the heat exchanger 122 of the heat exchange assembly 12 needs to be repaired or replaced, during the process of disassembling the heat exchange assembly 12, first detach the support member 121 of the heat exchange assembly 12 from the side surface 1111 of the frame body 111, and the support member 121 can be slightly inclined or elastically bent after being detached from the side surface 1111 of the frame body 111, so that the projection of the second plate body 1232 of the limiting member 123 after the inclination or elastic bending of the support member 121 can fall within the hollowed-out area 112, so that the heat exchange assembly 12 can be taken out through the hollowed-out area 112. Similar operations are performed when installing the heat exchange assembly 12 after repairing or replacing the heat exchanger 122 of the heat exchange assembly 12, which will not be elaborated herein.

[0071] Alternatively, the first plate body 1231 of the limiting member 123 can be detachably connected to the support member 121. When the heat exchanger 122 of the heat exchange assembly 12 needs to be repaired or replaced, during the process of disassembling the heat exchange assembly 12, the first plate body 1231 of the limiting member 123 can be detached from the support member 121 first, and then the support member 121 can be detached from the side surface 1111 of the frame body 111, so that the heat exchanger 122 and the support member 121 can be taken out through the hollow area 112 first, and then the limiting member 123 can be taken out through the hollow area 112. Of course, the support member 121 can also be detached from the side surface 1111 of the frame body 111 first, and then the limiting member 123 can be detached from the support member 121, which will not be elaborated here. Similarly, after the heat exchanger 122 of the heat exchange assembly 12 is repaired or replaced, similar operations are performed during the installation of the heat exchange assembly 12, which will not be elaborated here.

[0072] In some other more specific embodiments, the second plate body 1232 of the limiting member 123 can be directly connected to the support member 121.

[0073] Please refer to Figure 4 and Figure 6 , in some more specific embodiments, the number of the second plate bodies 1232 is two, and the two second plate bodies 1232 are arranged at intervals and both overlap on the top surface 1112 of the frame body 111.

[0074] In this embodiment, the two second plate bodies 1232 are arranged at intervals and both overlap on the top surface 1112 of the frame body 111, which can disperse the acting force received by the limiting member 123, extend the service life of the limiting member 123, and thus provide better support and stability for the heat exchange assembly 12.

[0075] In some more specific embodiments, the number of the second plate bodies 1232 can be more than two.

[0076] Please continue to refer to Figure 4 and Figure 6 , in some more specific embodiments, the heat exchange assembly 12 further includes a bolt 124, the screw rod of the bolt 124 connects the first plate body 1231 and the support member 121, and the head of the bolt 124 is located on the side of the support member 121 away from the side surface 1111.

[0077] In this embodiment, the first plate body 1231 and the second plate body 1232 are provided with coaxial through holes, and the screw rod of the bolt 124 passes through the through holes of the first plate body 1231 and the second plate body 1232 to connect the first plate body 1231 to the support member 121. The head of the bolt 124 is located on the side of the support member 121 away from the side surface 1111, thus providing sufficient space for disassembling and assembling the bolt 124.

[0078] The first plate body 1231 and the support member 121 are connected by bolts 124, realizing the detachable connection between the first plate body 1231 and the support member 121. At the same time, the bolts 124 can provide sufficient fastening force between the first plate body 1231 and the support member 121, ensuring a tight connection between the first plate body 1231 and the support member 121 and not easily loosening.

[0079] Exemplarily, in the projection direction perpendicular to the chassis 11, the projection area of the heat exchange assembly 12 can be less than or equal to the area of the hollowed-out region 112. However, in the projection direction perpendicular to the chassis 11, most of the projection of the heat exchange assembly 12 falls within the hollowed-out region 112. In other words, the projections of the heat exchanger 122 and the support member 121 of the heat exchange assembly 12 all fall within the hollowed-out region 112. However, since the second plate body 1232 of the limiting member 123 overlaps the top surface 1112 of the frame body 111, at least part of the projection of the second plate body 1232 of the limiting member 123 does not fall within the hollowed-out region 112.

[0080] When the heat exchanger 122 of the heat exchange assembly 12 needs to be repaired or replaced, during the process of disassembling the heat exchange assembly 12, the bolts 124 connecting the first plate body 1231 and the support member 121 can be disassembled first, and then the support member 121 can be detached from the side surface 1111 of the frame body 111. Thus, the heat exchanger 122 and the support member 121 can be taken out through the hollowed-out region 112 first, and then the limiting member 123 can be taken out through the hollowed-out region 112.

[0081] Or, when the heat exchanger 122 of the heat exchange assembly 12 needs to be repaired or replaced, during the process of disassembling the heat exchange assembly 12, the support member 121 can be detached from the side surface 1111 of the frame body 111 first, and then the bolts 124 connecting the first plate body 1231 and the support member 121 can be disassembled. Thus, the heat exchanger 122 and the support member 121 can be taken out through the hollowed-out region 112 first, and then the limiting member 123 can be taken out through the hollowed-out region 112.

[0082] When installing the heat exchange assembly 12 after the heat exchanger 122 of the heat exchange assembly 12 is repaired or replaced, the support member 121 can be connected to the side surface 1111 of the frame body 111 first, and then the first plate body 1231 and the support member 121 can be connected by bolts 124, thereby completing the installation of the heat exchange assembly 12.

[0083] In some other more specific embodiments, the first plate body 1231 and the support member 121 can also be detachably connected by means of snap connection or the like.

[0084] Please refer to Figure 4 、 Figure 5 and Figure 6, in some more specific embodiments, the support member 121 includes a first support plate 1211, a second support plate 1212, and an intermediate plate 1213. The first support plate 1211 is connected to the heat exchanger 122, the second support plate 1212 is connected to the side surface 1111, and the second support plate 1212 is offset from the first support plate 1211 in a direction perpendicular to the side surface 1111. Both ends of the intermediate plate 1213 are respectively connected to the first support plate 1211 and the second support plate 1212 and form a step. Among them, the limiting member 123 is connected to the first support plate 1211, and the limiting member 123 abuts against the step.

[0085] In this embodiment, the first support plate 1211 and the second support plate 1212 are offset in a direction perpendicular to the side surface 1111, and both ends of the intermediate plate 1213 are respectively connected to the first support plate 1211 and the second support plate 1212, so that the intermediate plate 1213 can form a step substantially perpendicular to the side surface 1111. The step is for the limiting member 123 to abut against and provides a stable support point for the limiting member 123, so that the limiting member 123 abuts against the step while lapping on the top surface 1112 of the frame body 111, further dispersing the acting force received by the limiting member 123. In addition, the step plays a role in positioning the installation of the limiting member 123. Simply put, during the process of installing the limiting member 123 on the first support plate 1211, first make the limiting member 123 abut against the step to preliminarily position the limiting member 123, and then adjust the limiting member 123 and install the limiting member 123 on the first support plate 1211. By means of the step of the intermediate plate 1213, the preliminary positioning of the limiting member 123 can be realized, which can reduce the installation difficulty of the limiting member 123 and save the installation time.

[0086] Exemplarily, in the projection direction perpendicular to the chassis 11, the projection area of the heat exchange assembly 12 can be less than or equal to the area of the hollowed-out area 112, but in the projection direction perpendicular to the chassis 11, most of the projection of the heat exchange assembly 12 falls within the hollowed-out area 112. In other words, the projections of the heat exchanger 122 and the support member 121 of the heat exchange assembly 12 all fall within the hollowed-out area 112, but since the second plate body 1232 of the limiting member 123 laps on the top surface 1112 of the frame body 111, at least part of the projection of the second plate body 1232 of the limiting member 123 does not fall within the hollowed-out area 112.

[0087] When the heat exchanger 122 of the heat exchange assembly 12 needs to be repaired or replaced, during the process of disassembling the heat exchange assembly 12, the limiting member 123 can be first detached from the first support plate 1211 of the support member 121, and then the second support plate 1212 of the support member 121 can be detached from the side surface 1111 of the frame body 111, so that the heat exchanger 122 and the support member 121 can be first taken out through the hollowed-out area 112, and then the limiting member 123 can be taken out through the hollowed-out area 112.

[0088] Alternatively, when the heat exchanger 122 of the heat exchange assembly 12 needs to be repaired or replaced, during the disassembly of the heat exchange assembly 12, the second support plate 1212 of the support member 121 can be detached from the side surface 1111 of the frame body 111 first, and then the limiting member 123 can be detached from the first support plate 1211 of the support member 121, so that the heat exchanger 122 and the support member 121 can be taken out through the hollow area 112 first, and then the limiting member 123 can be taken out through the hollow area 112.

[0089] When installing the heat exchange assembly 12 after the heat exchanger 122 of the heat exchange assembly 12 is repaired or replaced, the second support plate 1212 of the support member 121 can be connected to the side surface 1111 of the frame body 111 first, and then the limiting member 123 can be abutted against the middle plate 1213 and adjusted. Finally, the limiting member 123 is connected to the first support plate 1211 of the support member 121, thus completing the installation of the heat exchange assembly 12.

[0090] In some other more specific embodiments, the first support plate 1211 and the second support plate 1212 are not staggered in the direction perpendicular to the side surface 1111, and the first support plate 1211 is connected to the second support plate 1212, and the first support plate 1211 forms a step.

[0091] In some more specific embodiments, the step is flush with the top surface 1112 of the frame body 111.

[0092] It should be noted that the step being flush with the top surface 1112 of the frame body 111 means that the step surface of the step is flush with the top surface 1112 of the frame body 111.

[0093] The step being flush with the top surface 1112 of the frame body 111 enables the lower surface of the limiting member 123 to fit the step surface of the step and the top surface 1112 of the frame body 111 simultaneously when the limiting member 123 abuts against the step surface of the step and lapped on the top surface 1112 of the frame body 111, that is, a surface contact is formed between the limiting member 123 and the step and between the limiting member 123 and the frame body 111, increasing the contact area between the limiting member 123 and the step and between the limiting member 123 and the frame body 111, thereby reducing the pressure formed between the limiting member 123 and the step and between the limiting member 123 and the frame body 111, so as to achieve the purpose of protecting the limiting member 123, the frame body 111 and the middle plate 1213.

[0094] In some other more specific embodiments, the step surface of the step can be inclined relative to the top surface 1112 of the frame body 111.

[0095] In some embodiments, the support member 121 is welded to the outside of the heat exchanger 122.

[0096] The support member 121 is welded to the outer side of the heat exchanger 122, which can ensure a firm bond between the support member 121 and the heat exchanger 122, so that there is strong connection stability between the support member 121 and the heat exchanger 122.

[0097] In some other embodiments, the support member 121 and the heat exchanger 122 may also be detachably connected.

[0098] Please refer to Figure 5 , in some embodiments, the heat exchanger 122 includes a water inlet 1221 and a water outlet 1222 that face the same direction. The number of support members 121 is three, and the outer side surfaces 1111 of every two adjacent support members 121 are perpendicular to each other, and the outer side surfaces 1111 of the two support members 121 on both sides of the water inlet 1221 are perpendicular to the direction of the water inlet 1221.

[0099] Among them, the support member 121 has opposite outer side surfaces 1111 and inner side surfaces 1111, and the inner side surface 1111 of the support member 121 is connected to the heat exchanger 122.

[0100] Exemplarily, the heat exchanger 122 has different first, second, third, and fourth orientations on the horizontal plane, the first orientation is opposite to the third orientation, and the second orientation is opposite to the fourth orientation. Both the water inlet 1221 and the water outlet 1222 face the first orientation, and the outer side surfaces 1111 of the three support members 121 face the second, third, and fourth orientations respectively.

[0101] Providing three support members 121 can position the heat exchanger 122 in space, facilitating subsequent operations on the heat exchanger 122, such as facilitating the connection of the water inlet 1221 and the water outlet 1222 of the heat exchanger 122 to other components in the installation space of the heat pump unit 1.

[0102] In some other embodiments, the number of support members 121 may also be two.

[0103] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
