[0033] Example 1

[0034] like Figure 1 、 Figure 2 As shown, a specific implementation of the heat pump unit provided in this embodiment includes: an upper part and a lower part connected by assembly, wherein the upper part includes: a water receiving tray assembly 1, a fin heat exchanger 2, a corner column 12 and a fan assembly 4, the fin heat exchanger 2 is installed on the water receiving tray assembly 1, the corner column 12 is vertically installed at the corner position of the water receiving tray assembly 1, and the fan assembly 4 is installed above the fin heat exchanger 2 and connected to the upward extending end of the corner column 12; the lower part includes: a base assembly 5, the base assembly 5 is installed below the water receiving tray assembly 1 and connected to the downward extending end of the corner column 12.

[0035] The heat pump assembly provided in this embodiment is assembled by an upper part and a lower part. During the installation process, the upper part and the lower part can be installed separately and then assembled together, thereby improving installation efficiency.

[0036] like Figure 3 As shown, in the heat pump unit provided by this embodiment, the fin heat exchanger 2 has multiple fin heat exchangers 2 connected in sequence on the water receiving tray assembly 1. With such an arrangement, multiple fin heat exchangers 2 can be used to perform heat exchange for multiple systems respectively. Specifically, in this embodiment, the fin heat exchanger 2 has four fin heat exchangers 2 connected in sequence to form a matrix structure, that is, the four fin heat exchangers 2 are connected in sequence around the center to form a rectangular structure. During installation, one fin heat exchanger 2 is hoisted at a time. First, two adjacent fin heat exchangers 2 are hoisted and placed on the same side of the water receiving tray assembly 1, and then a middle partition 14 is installed on the water receiving tray assembly 1. The middle partition 14 and the two adjacent fin heat exchangers 2 form a heat exchange air cavity together, and then the other two fin heat exchangers 2 are hoisted. With such an arrangement, a heat pump with four fin heat exchangers 2 is formed, which can provide two heat exchange air cavities and improve the efficiency during operation. Of course, the above description is not restrictive. In some alternative embodiments, the fin heat exchanger 2 may be provided with only one, two, or more fin heat exchangers, and the middle partition plate 14 may be omitted.

[0037] like Figure 3As shown, in the heat pump unit provided in this embodiment, a middle partition 14 is vertically provided on the water receiving pan assembly 1, and the middle partition 14 and at least one of the fin heat exchangers 2 form a heat exchange air cavity. Specifically, in this embodiment, the fin heat exchanger 2 is a bent structure, and the opening is located in the middle partition 14 to form a heat exchange air cavity for the passage of hot air. The middle partition 14 can form a heat exchange air cavity with only one of the fin heat exchangers 2, or it can form a heat exchange air cavity with two or more of the fin heat exchangers 2.

[0038] like Figure 3 As shown, in this embodiment, the middle partition 14 and the two adjacent fin heat exchangers 2 together form a heat exchange air cavity. That is, the four fin heat exchangers 2 provided in this embodiment cooperate with the middle partition 14 to form two heat exchange air cavities. Such a setting can be used to exchange heat between two systems. Figure 3 、 Figure 4 As shown, in the heat pump unit provided in this embodiment, the fan assembly 4 includes: a top beam frame 8 and a plurality of fans 9, and the plurality of fans 9 are respectively installed on the top beam frame 8. Specifically, in this embodiment, the plurality of fans 9 are arranged on the top beam frame 8 in a one-to-one correspondence with the fin heat exchanger 2. With such an arrangement, during installation, the plurality of fans 9 can be first installed on the top beam frame 8 in sequence, and then hoisted as a whole to the top of the fin heat exchanger 2, thereby saving the number of hoisting times and improving the installation efficiency. Of course, the above description is not restrictive. In some alternative embodiments, the fan 9 can also be provided with only one, two or more fans.

[0039] like Figure 5 、 Figure 6 As shown, in the heat pump unit provided in this embodiment, the water receiving pan assembly 1 includes: a middle crossbeam frame 10 and a plurality of water receiving pans 11, and the plurality of water receiving pans 11 are respectively mounted on the middle crossbeam frame 10. Specifically, in this embodiment, the plurality of water receiving pans 11 are arranged in a one-to-one correspondence with the fin heat exchangers 2, and one fin heat exchanger 2 is mounted on one water receiving pan 11. During the hoisting process, the fin heat exchanger 2 is positioned by the slot on the water receiving pan 11, and a support pad can be provided on the water receiving pan 11 to support the fin heat exchanger 2. With such an arrangement, water is collected through a separate water receiving pan 11 under each fin heat exchanger 2, which can ensure that the water flowing down from each fin heat exchanger 2 can be smoothly discharged.

[0040] like Figure 3 、 Figure 4As shown, the heat pump unit provided in this embodiment further includes an upper center column 3, which is vertically arranged on the edge of the center crossbeam frame 10 and extends upward to connect with the fan assembly 4. In other words, in this embodiment, the upper center column 3 is installed on the edge between two adjacent corners of the center crossbeam frame 10. This arrangement does not affect the installation of the corner columns 12, and can cooperate with the corner columns 12 to better support the fan assembly 4.

[0041] like Figure 3 As shown, in this embodiment, the fin heat exchanger 2 is designed with a tilted structure having a specific tilt angle to achieve effective heat exchange with the air. This tilted structure creates an installation space between two adjacent fin heat exchangers 2. The upper center column 3 is not only arranged on the edge of the center crossbeam frame 10, but is also specially designed to support the outer side of the connection between two adjacent fin heat exchangers 2. When the upper center column 3 is installed vertically in this position, it can be more easily installed.

[0042] Specifically, the tilt angle of the tilted structure of the fin heat exchanger 2 has been precisely calculated to ensure that it can accommodate the setting of the upper center column 3 while not affecting the heat exchange efficiency of the heat exchanger. The tilted structure on the fin heat exchanger 2 allows the heat exchange air chamber formed by a single fin heat exchanger 2 to adapt to the projected shape of a single fan 9. The adaptation mentioned here means that the two projected areas are close in size. In other words, the projection of the fan 9 is tangent to part of the heat exchange air chamber. This setting can ensure the suction of the fan 9 while ensuring that the heat pump system can operate stably, efficiently and with low noise. Specifically, in the case where the size difference between the fin heat exchanger and the fan is large, if the size of the fin heat exchanger is larger than the size of the fan, the fan will easily suffer from insufficient power, resulting in low suction and weak cooling capacity; if the size of the fin heat exchanger is smaller than the size of the fan, the fin heat exchanger is relatively small, and the gap between the fin heat exchanger and the fan will be large, so the noise generated when the wind passes through will increase, seriously affecting the user experience; therefore, it is necessary to ensure that the outer peripheral surface of the fan and the vertical plane where the fin heat exchanger is located are tangent, so that the sizes of the fan and the fin heat exchanger can be matched, thereby ensuring that the heat pump system can operate stably, efficiently and with low noise.

[0043] like Figure 3As shown, in this embodiment, the upper center column 3 is connected to the water receiving pan assembly 1 via a connecting piece, and the connecting piece includes a triangular plate 7 fixedly connected to both sides of the bottom end of the upper center column 3. During installation, the upper center column 3 is connected to the water receiving pan assembly 1 via the triangular plate 7, which can improve the firmness of the connection between the upper center column 3 and the water receiving pan assembly 1. Of course, the above description is not restrictive. In some alternative embodiments, the connecting piece can also be a fastener, such as a bolt. Alternatively, the connecting piece can be omitted, and the upper center column 3 can be directly welded to the water receiving pan assembly 1.

[0044] like Figure 2 As shown, the heat pump unit provided in this embodiment further includes a middle lower column 6, which is vertically connected to the edge of the middle crossbeam frame 10 and extends downward to connect with the base assembly 5. In other words, in this embodiment, the middle lower column 6 is installed at the edge between two adjacent corners of the middle crossbeam frame 10. This arrangement does not affect the installation of the corner columns 12, and can cooperate with the corner columns 12 to better connect the base assembly 5.

[0045] like Figure 2 、 Figure 5 As shown, in this embodiment, the middle crossbeam frame 10 is composed of four crossbeams on all sides and two crossbeams in the middle. The two middle crossbeams are connected in an overlapping manner, with one crossbeam overlapping the other crossbeam to enhance the stability and load-bearing capacity of the structure. In order to provide additional support for the middle crossbeam, a support column 13 is vertically provided at the middle position on the base assembly 5, and the support column 13 extends upward and is connected to the middle crossbeam frame 10. Specifically, the support column 13 can be provided at the intersection below the overlapped crossbeams, or two support columns can be provided, each located below the direction of the overlapped crossbeams. The support column 13 can be firmly mounted on the base assembly 5 by bolts, welding or other appropriate fixing methods to ensure the stability and load-bearing capacity of the middle crossbeam frame 10.

[0046] It should be noted that, in this embodiment, the corner column 12 is provided at the corner position of the middle cross beam frame 10 , specifically at the intersection of two mutually perpendicular edges of the middle cross beam frame 10 .

[0047] The upper center column 3 and the lower center column 6 are arranged on the edge of the center cross beam frame 10 , specifically located on one side edge of the center cross beam frame 10 , adjacent to the corner column 12 .

[0048] Example 2

[0049] This embodiment provides a method for installing a heat pump unit, comprising the following steps: Figure 2 As shown, the heat pump unit is divided into an upper part and a lower part, and the upper part and the lower part are installed separately, and then the upper part and the lower part are assembled;

[0050] During installation of the upper portion, the finned heat exchanger 2 is first mounted on the water tray assembly 1, and then the corner columns 12 and fan assembly 4 are installed on the water tray assembly 1. The corner columns 12 are vertically mounted at the corner of the water tray assembly 1, and the fan assembly 4 is mounted above the finned heat exchanger 2 and connected to the upwardly extending ends of the corner columns 12. This arrangement, in which the finned heat exchanger 2 is mounted on the water tray 11 first and the corner columns 12 are installed later, avoids scratches on the finned heat exchanger 2 by the corner columns 12 when the finned heat exchanger 2 is hoisted.

[0051] like Figure 1 、 Figure 2 As shown, the installation method of the heat pump unit provided in this embodiment further includes, during the installation of the upper portion, vertically connecting an upper center column 3 to the edge of the water tray assembly 1, wherein the upper center column 3 extends upward to connect to the fan assembly 4. In other words, in this embodiment, the upper center column 3 is installed on the edge between two adjacent corners of the center crossbeam frame 10 of the water tray assembly 1. This arrangement does not affect the installation of the corner columns 12, and can cooperate with the corner columns 12 to better support the fan assembly 4.

[0052] like Figure 1 、 Figure 2 As shown, in the heat pump unit installation method provided in this embodiment, the corner column 12 is connected to the water tray assembly 1 via fasteners. This arrangement allows for detachable installation of the corner column 12 from the water tray 11 and facilitates assembly of the corner column 12. Of course, the above description is not restrictive. In alternative embodiments, the corner column 12 may also be connected to the water tray assembly 1 using other methods, such as welding.

[0053] like Figure 2 As shown, in the installation method of the heat pump unit provided in this embodiment, the lower portion includes a base assembly 5. When the upper portion and the lower portion are assembled, the base assembly 5 is installed below the water tray assembly 1 and connected to the downwardly extending end of the corner column 12. Specifically, the base assembly 5 and the corner column 12 can be connected by bolts or welding.

[0054] like Figure 1As shown, in the installation method of the heat pump unit provided in this embodiment, when assembling the upper part and the lower part, it also includes: vertically connecting the middle and lower columns 6 on the four sides of the water receiving pan assembly 1, and the middle and lower columns 6 extend downward to connect with the base assembly 5. That is to say, in this embodiment, after the base assembly 5 is connected to the water receiving pan assembly 1 through the corner columns 12, the middle and lower columns 6 are installed, thereby strengthening the stability of the connection between the base assembly 5 and the water receiving pan assembly 1 through the middle and lower columns 6. It should be noted that, in this embodiment, the corner columns 12 are an integrated structure. With such an arrangement, the stability of the connection between the upper part and the lower part can be improved by installing the corner columns 12. Of course, the above description is not restrictive. In some alternative embodiments, the corner columns 12 can also adopt a split structure.

[0055] like Figure 2 As shown, in the installation method of the heat pump unit provided in this embodiment, the lower part further includes: a support column 13, the support column 13 is installed in the middle position of the base assembly 5, and the support column 13 extends upward to be connected to the water receiving pan assembly 1. Specifically, the support column 13 extends upward to be connected to the middle crossbeam frame 10 of the water receiving pan assembly 1. Figure 5 As shown, in this embodiment, the central crossbeam frame 10 is composed of four surrounding crossbeams and two intersecting crossbeams in the middle. The two central crossbeams are connected by overlapping, with one crossbeam overlapping the other, to enhance the stability and load-bearing capacity of the structure. Two support columns 13 are provided, each extending upward to connect below the overlapping crossbeams in the central crossbeam frame 10, thereby enhancing the stability and load-bearing capacity of the structure.

[0056] like Figure 3 As shown, in the installation method of the heat pump unit provided in this embodiment, the fin heat exchanger 2 has multiple fin heat exchangers 2 connected in sequence on the water receiving tray assembly 1. With this arrangement, multiple fin heat exchangers 2 can be used to perform heat exchange for multiple systems. Specifically, in this embodiment, the fin heat exchangers 2 have four fin heat exchangers 2 connected in sequence to form a matrix structure, that is, the four fin heat exchangers 2 are connected in sequence around the center to form a rectangular structure. During installation, one fin heat exchanger 2 is hoisted at a time. First, two adjacent fin heat exchangers 2 are hoisted and placed on the same side of the water receiving tray assembly 1. Then, a middle partition 14 is installed on the water receiving tray assembly 1. The middle partition 14 and the two adjacent fin heat exchangers 2 together form a heat exchange air cavity, and then the other two fin heat exchangers 2 are hoisted. With this arrangement, a heat pump with four fin heat exchangers 2 is formed, which can provide two heat exchange air cavities and improve efficiency during operation. Of course, the above description is not restrictive. In some alternative embodiments, the fin heat exchanger 2 can also be provided with only one, two, or more fin heat exchangers.

[0057] like Figure 3 As shown, the installation method of the heat pump unit provided in this embodiment further includes: installing a sealing plate 15 at the connection between two adjacent fin heat exchangers 2. The installation of the sealing plate 15 can ensure the sealing of the heat exchange air cavity formed by the fin heat exchanger 2.

[0058] like Figure 2 、 Figure 3 As shown, in the installation method of the heat pump unit provided in this embodiment, triangular plates 7 are respectively provided on both sides of the bottom end of the upper center column 3, and the upper center column 3 is vertically fixedly connected to the edges of the water receiving pan assembly 1 via the triangular plates 7. In this arrangement, the provision of the triangular plates 7 can improve the tightness of the connection between the upper center column 3 and the water receiving pan assembly 1. Of course, the above description is not restrictive. In some alternative embodiments, the upper center column 3 can also be connected to the water receiving pan assembly 1 using other connecting members, such as bolts.

[0059] like Figure 3 As shown, in the installation method of the heat pump unit provided in this embodiment, the fan assembly 4 includes: a top beam frame 8 and multiple fans 9. During installation, the multiple fans 9 are first mounted on the top beam frame 8, and then the entire assembly is hoisted above the fin heat exchanger 2. This arrangement can reduce the number of hoisting times and improve production efficiency.

[0060] like Figure 1 As shown, in the installation method of the heat pump unit provided in this embodiment, the water receiving pan assembly 1 includes: a middle cross beam frame 10 and multiple water receiving pans 11. During installation, the multiple water receiving pans 11 are first installed on the middle cross beam frame 10, and then the fin heat exchanger 2 is installed on the water receiving pan 11 in sequence.

[0061] like Figure 7 As shown in the figure, an improved installation method for the heat pump unit is used. First, the corner columns 12 and the middle and lower columns 6 are installed on the water tray assembly 1, and then the finned heat exchanger 2 is hoisted onto the water tray assembly 1. This installation method greatly increases the chance of the large finned heat exchanger 2 being scratched by the columns because the finned heat exchanger 2 is too heavy to control in mid-air.

[0062] This embodiment improves the above-mentioned installation method by dividing the heat pump assembly into an upper part and a lower part. When installing the upper part, the fin heat exchanger 2 is first installed on the water receiving pan assembly 1, and then the corner column 12 and the upper center column 3 are installed on the water receiving pan assembly 1, thereby solving the problem of the fin heat exchanger 2 being scratched by the column when installing.

[0063] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
