[0003] Chinese patent document CN220229730U discloses a heat pump chassis and a heat pump, including a fin support base and fins, wherein the fin support base is provided with corner columns on all four sides. When the fins are hoisted onto the fin support base, it is difficult to control the direction in the air because the fins are too heavy, which greatly increases the probability of the large fins being scratched by the corner columns.

[0004] The fins are the largest part of the overall appearance. Scratching the fins not only affects the appearance, but also has the risk of flipping the fins, which will seriously hinder the airflow, thereby reducing the total heat transfer power and increasing noise. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the fin heat exchanger is easily scratched when the heat pump unit is installed, thereby providing an installation method for the heat pump unit.

[0012] Optionally, the lower part further includes: a support column, which is installed in the middle position of the base assembly and extends upward to be connected to the water tray assembly.

[0013] Optionally, the fin heat exchanger has a plurality of fin heat exchangers connected in sequence on the water receiving tray assembly.

[0014] Optionally, when installing the fin heat exchanger, first hoist two adjacent fin heat exchangers, and then vertically install a middle partition on the water receiving tray assembly, so that a heat exchange air cavity is formed together with the middle partition and the two adjacent fin heat exchangers.

[0015] Optionally, the method further comprises: installing a sealing plate at the connection between two adjacent fin heat exchangers.

[0033] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] Example 1

[0035] 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.

[0036] 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 the two parts can be assembled, thereby improving the installation efficiency.

[0037] like Figure 3As shown, in 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. In this way, multiple fin heat exchangers 2 can be used to exchange heat 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, and two adjacent fin heat exchangers 2 are hoisted on the same side of the water receiving tray assembly 1, and then the 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. In this way, 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 can also be set to only one, two or more.

[0038] like Figure 3 As shown, in the heat pump unit provided in this embodiment, the fin heat exchanger 2 is a bent structure, and can form a heat exchange air cavity with the middle partition plate 14 for the passage of heat exchange air. The middle partition plate 14 can form a heat exchange air cavity with only one fin heat exchanger 2, or can form a heat exchange air cavity with two or more fin heat exchangers 2.

[0039] like Figure 3 As shown, in this embodiment, the middle partition plate 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 plate 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 mounted 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 above 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, and in some alternative embodiments, the fan 9 can also be provided with only one, two or more fans, etc.

[0040] like Figure 5 , Figure 6As shown, in the heat pump unit provided in this embodiment, the water receiving pan assembly 1 includes: a middle cross beam frame 10 and a plurality of water receiving pans 11, and the plurality of water receiving pans 11 are respectively mounted on the middle cross beam frame 10. Specifically, in this embodiment, the plurality of water receiving pans 11 are arranged one-to-one 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 arranged on the water receiving pan 11 to support the fin heat exchanger 2. With such an arrangement, water is collected by a separate water receiving pan 11 under each fin heat exchanger 2, so that the water flowing down from each fin heat exchanger 2 can be smoothly discharged.

[0041] like Figure 3 , Figure 4 As shown, the heat pump unit provided in this embodiment further includes: an upper center column 3, the upper center column 3 is vertically arranged on the edge of the middle cross beam frame 10, and the upper center column 3 extends upward to connect with the fan assembly 4. That is to say, in this embodiment, the installation position of the upper center column 3 is on the edge between two adjacent corner positions of the middle cross beam frame 10. Such an arrangement will not affect the installation of the corner column 12, and can cooperate with the corner column 12 to better support the fan assembly 4.

[0042] like Figure 3 As shown, in this embodiment, the fin heat exchanger 2 is designed to have an inclined structure with a specific inclination angle in order to achieve effective heat exchange with the air. The setting of the inclined structure forms an installation space between two adjacent fin heat exchangers 2. The upper center column 3 is not only arranged on the edge of the middle cross beam 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 vertically installed in this position, the installation of the upper center column 3 can be better facilitated.

[0043] Specifically, the inclination angle of the inclined structure of the fin heat exchanger 2 is precisely calculated to ensure that it can accommodate the setting of the upper center column 3 without affecting the heat exchange efficiency of the heat exchanger. The inclined structure on the fin heat exchanger 2 makes the heat exchange air cavity formed by a single fin heat exchanger 2 match the projected shape of a single fan 9. The matching 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 cavity. Such a 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 of the fin heat exchanger and the fan is quite different, if the size of the fin heat exchanger is larger than the size of the fan, the fan will easily become underpowered, resulting in small 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 to each other, so as to ensure that the sizes of the fan and the fin heat exchanger are matched, thereby ensuring that the heat pump system can operate stably, efficiently and with low noise.

[0044] like Figure 3 As shown, in this embodiment, the upper center column 3 is connected to the water receiving pan assembly 1 through 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 through 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, and 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.

[0045] like Figure 2 As shown, the heat pump unit provided in this embodiment further includes: a middle lower column 6, the middle lower column 6 is vertically connected to the edge of the middle cross beam frame 10, and the middle lower column 6 extends downward to connect with the base assembly 5. That is to say, in this embodiment, the installation position of the middle lower column 6 is the edge between two adjacent corner positions of the middle cross beam frame 10. Such a setting will not affect the installation of the corner column 12, and can cooperate with the corner column 12 to better connect the base assembly 5.

[0046] like Figure 2 , Figure 5As shown, in this embodiment, the middle cross beam frame 10 is composed of four cross beams around and two cross beams in the middle. The two middle cross beams are connected in an overlapping manner, and one of the cross beams is overlapped on top of the other cross beam to enhance the stability and bearing capacity of the structure. In order to provide additional support for the middle cross beam, a support column 13 is vertically arranged in the middle position on the base assembly 5, and the support column 13 extends upward to connect with the middle cross beam frame 10. Specifically, the support column 13 can be arranged at the intersection below the overlapped cross beam, or two support columns can be arranged, respectively located below the direction of the overlapped cross beam. 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 bearing capacity of the middle cross beam frame 10.

[0047] It should be noted that, in the present embodiment, the corner column 12 is disposed at a corner position of the middle cross beam frame 10 , specifically, at an intersection of two mutually perpendicular edges of the middle cross beam frame 10 .

[0048] 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 .

[0049] Example 2

[0050] 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, the upper part and the lower part are installed respectively, and then the upper part and the lower part are assembled;

[0051] Among them, in the installation of the upper part, the fin heat exchanger 2 is first installed on the water tray assembly 1, and then the corner column 12 and the fan assembly 4 are installed on the water tray assembly 1, the corner column 12 is vertically installed at the corner position of the water tray assembly 1, and the fan assembly 4 is installed above the fin heat exchanger 2 and connected to the upward extension end of the corner column 12. In this way, the fin heat exchanger 2 is first installed on the water tray 11, and the corner column 12 is then installed, which can avoid the problem of the corner column 12 scratching the fin heat exchanger 2 when the fin heat exchanger 2 is hoisted.

[0052] like Figure 1 , Figure 2As shown, in the installation method of the heat pump unit provided in this embodiment, in the installation of the upper part, it also includes: vertically connecting the upper center column 3 on the edge of the water tray assembly 1, and the upper center column 3 extends upward to connect with the fan assembly 4. That is to say, in this embodiment, the installation position of the upper center column 3 is on the edge between two adjacent corner positions of the middle cross beam frame 10 of the water tray assembly 1. Such an arrangement will not affect the installation of the corner column 12, and can cooperate with the corner column 12 to better support the fan assembly 4.

[0053] like Figure 1 , Figure 2 As shown, in the installation method of the heat pump unit provided in this embodiment, the corner column 12 is connected to the water receiving pan assembly 1 by a fastener. In this way, the corner column 12 and the water receiving pan 11 can be detachably installed, and the assembly of the corner column 12 is convenient. Of course, the above description is not restrictive. In some alternative embodiments, the corner column 12 can also be connected to the water receiving pan assembly 1 in other ways, for example, it can be connected to the water receiving pan assembly 1 by welding, etc.

[0054] like Figure 2 As shown, in the installation method of the heat pump unit provided in this embodiment, the lower part includes: a base assembly 5. When the upper part and the lower part are assembled, the base assembly 5 is installed below the water receiving 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.

[0055] like Figure 1 As 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: connecting the middle and lower columns 6 vertically 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, so as to strengthen 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.

[0056] like Figure 2As shown, in the installation method of the heat pump unit provided in this embodiment, the lower part also 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 middle cross beam frame 10 is composed of four cross beams around and two cross beams in the middle. The two cross beams in the middle are connected in an overlapping manner, and one cross beam is overlapped on top of the other cross beam to enhance the stability and bearing capacity of the structure. Two support columns 13 are provided, which extend upward and are connected to the bottom of the overlapped cross beams in the middle cross beam frame 10, thereby enhancing the stability and bearing capacity of the structure.

[0057] 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 fins connected in sequence on the water receiving tray assembly 1. In this way, multiple fin heat exchangers 2 can be used for heat exchange for multiple systems respectively. Specifically, in this embodiment, the fin heat exchanger 2 has four fins 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, and two adjacent fin heat exchangers 2 are hoisted on the same side of the water receiving tray assembly 1, and then the middle partition 14 is installed on the water receiving tray assembly 1, and 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. In this way, 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 can also be set to only one, two or more.

[0058] 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 sealing plate 15 can ensure the sealing of the heat exchange air cavity formed by the fin heat exchanger 2.

[0059] like Figure 2 , Figure 3As shown, in the installation method of the heat pump unit provided in this embodiment, triangle 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 through the triangle plates 7. In this way, the tightness of the connection between the upper center column 3 and the water receiving pan assembly 1 can be improved through the setting of the triangle plates 7. 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 by other connecting parts, such as bolt connection.

[0060] 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 a plurality of fans 9. During installation, the plurality of fans 9 are first installed on the top beam frame 8, and then hoisted as a whole to the top of the fin heat exchanger 2. Such an arrangement can reduce the number of hoisting times and improve production efficiency.

[0061] 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 a plurality of water receiving pans 11. During installation, the plurality of 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.

[0062] like Figure 7 As shown in the figure, an improved installation method of the heat pump unit is to first install the corner column 12 and the middle and lower column 6 on the water receiving tray assembly 1, and then hoist the fin heat exchanger 2 onto the water receiving tray assembly 1. In such installation, since the fin heat exchanger 2 is too heavy to control the direction in the air, the probability of the large fin heat exchanger 2 being scratched by the column is greatly increased.

[0063] This embodiment improves the above-mentioned installation method and divides 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 middle 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.

[0064] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the present invention.
