Description

Technical Field

[0001] This utility model relates to the field of heat pump technology, and in particular to a housing assembly and a heat pump host. Background Technology

[0002] Currently, during operation, heat pump units compress the refrigerant using a compressor inside the unit casing. For example, in the refrigeration cycle, the compressor compresses the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas, a process that generates a significant amount of heat. Furthermore, the refrigerant releases heat and liquefies in the condenser, further increasing the internal temperature of the unit.

[0003] When the internal temperature of the compressor unit is too high, it will affect the compressor's performance. Overheating of the compressor may reduce its efficiency or even trigger the overheat protection mechanism, causing it to shut down. Prolonged exposure to high temperatures will significantly shorten the compressor's lifespan.

[0004] To improve heat dissipation, ventilation holes are often added to the casing. However, creating these holes actually involves removing material from the casing. From a materials mechanics perspective, reducing material means a decrease in load-bearing capacity, and its ability to resist external forces such as bending, tension, and compression will also weaken accordingly. When there are many ventilation holes and their distribution is uneven, it not only leads to uneven heat dissipation, but also significantly reduces the strength of the casing due to the increased material removal. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, the present invention provides a housing assembly and a heat pump host, wherein the heat dissipation holes are evenly and closely arranged in the heat dissipation area, so that the interior of the host housing can effectively dissipate heat through the heat dissipation area on the panel.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A housing assembly includes a main housing and a panel. The panel has a connecting portion around its periphery, and the connecting portion is detachably connected to the main housing. The panel has several heat dissipation areas, and each heat dissipation area has multiple heat dissipation holes. The edge shape of the heat dissipation area is the same as the shape of the heat dissipation holes.

[0008] Furthermore, the heat dissipation holes are honeycomb holes, and the edges of the heat dissipation area are honeycomb-shaped.

[0009] Furthermore, a reinforcement zone is provided on the outer periphery of the heat dissipation zone, and two adjacent heat dissipation zones are connected through the reinforcement zone.

[0010] Furthermore, the panel has a heat dissipation surface, and both sides of the panel extend in a direction away from the heat dissipation surface to form connecting side plates, and the heat dissipation area extends from the panel to the connecting side plates.

[0011] Furthermore, the ends of the connecting side plates extend inward to form a first side flange and a second side flange, respectively. The first side flange is provided with a first connector, and the second side flange is provided with a second connector. Both the first connector and the second connector are used to connect with the main housing.

[0012] Furthermore, the two ends of the panel extend away from the heat dissipation surface to form connecting end plates, and the two connecting end plates are respectively provided with a third connector and a fourth connector; the first connector, the second connector, the third connector and the fourth connector form the connecting part.

[0013] Furthermore, the first connector includes a connecting plate, which extends from the end of the first side flange in a direction away from the heat dissipation surface; a connecting slot is provided at the connection between the connecting plate and the first side flange, and a connecting hole is provided on the connecting plate;

[0014] The second connector includes a hook, one end of which is connected to the second side flange.

[0015] Furthermore, one of the connecting end plates extends inward to form an end flange, and the third connecting member includes a connecting plate segment and an abutting plate segment. The two ends of the connecting plate segment are respectively connected to one end of the end flange and one end of the abutting plate segment. The abutting plate segment and the end flange are arranged opposite to each other and a snap-fit ​​interval is formed between them. The end flange is provided with a positioning hole and a slot.

[0016] Furthermore, the fourth connector includes a mounting plate, one end of which is connected to the end of another connecting end plate, and the other end of which extends away from the connecting end plate. The mounting plate is provided with a connecting hole.

[0017] A heat pump unit includes the aforementioned housing assembly.

[0018] In summary, the housing assembly and heat pump unit provided by this utility model have the following technical effects:

[0019] 1) Since the heat dissipation area and the heat dissipation holes have the same shape, the heat dissipation holes can be evenly arranged along the middle and edges of the heat dissipation area. There will be no unusable gaps caused by shape differences in the heat dissipation area. This allows more heat dissipation holes to be set in a limited heat dissipation area, thereby improving heat dissipation efficiency. The inside of the main unit can effectively dissipate heat through the heat dissipation area on the panel.

[0020] 2) Since the heat dissipation area can utilize a limited area to set more heat dissipation holes, it can avoid setting heat dissipation holes in other parts of the panel, thereby making full use of the area of ​​the heat dissipation area and reducing the number of openings in other areas. This can ensure the strength of the panel; at the same time, it can alleviate the problem of panel strength reduction caused by openings. Attached Figure Description

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] Example 1

[0032] This utility model discloses a housing assembly, which includes a main housing and a panel 10. For details, please refer to... Figure 1 and Figure 3 The panel 10 has a connecting part around its periphery, and the connecting part is detachably connected to the main unit casing. The panel 10 has several heat dissipation areas 11, each with multiple heat dissipation holes, and the edge shape of the heat dissipation area 11 is the same as the shape of the heat dissipation holes.

[0033] Based on this structure, when using the housing assembly of this utility model, the panel 10 can be connected to the main housing via its peripheral connecting part. When the heat pump main unit starts running, internal components such as the compressor and condenser generate heat, which accumulates inside the main housing. At this time, the heat dissipation area 11 on the panel 10 begins to function, and the heat is dissipated to the external environment through multiple heat dissipation holes in the heat dissipation area 11.

[0034] The heat dissipation holes can be round or square, and correspondingly, the edges of the heat dissipation area 11 are round, square, or rectangular. Since the heat dissipation area 11 and the heat dissipation holes have the same shape, the heat dissipation holes can be evenly distributed along the center and edges of the heat dissipation area 11. There will be no unusable gaps caused by shape differences within the heat dissipation area 11. This allows for more heat dissipation holes to be set within the limited area of ​​the heat dissipation area 11, thereby improving heat dissipation efficiency.

[0035] Therefore, the heat dissipation holes can be evenly distributed within the heat dissipation area 11, and the spacing between the holes is more uniform, avoiding the chaotic arrangement caused by inconsistent shapes, thus ensuring the uniformity of heat dissipation. The evenly distributed heat dissipation holes enable heat to be dissipated more evenly, preventing localized overheating and improving the overall heat pump unit's heat dissipation efficiency.

[0036] At the same time, since the heat dissipation area 11 can make use of a limited area to set more heat dissipation holes, it can avoid setting heat dissipation holes in other parts of the panel 10, thereby making full use of the area of ​​the heat dissipation area 11 and reducing the number of openings in other areas, thus ensuring the strength of the panel 10.

[0037] Furthermore, since the connecting part is detachable, the panel 10 can be removed from the main unit housing when maintenance or replacement of parts is required. After long-term use, the panel 10 can be easily removed for cleaning or replacement.

[0038] Furthermore, the heat dissipation holes are honeycomb holes, and the edges of the heat dissipation area 11 are honeycomb-shaped.

[0039] Compared to round or square holes, hexagonal holes have an advantage in terms of density when using a honeycomb structure for heat dissipation. Within a given heat dissipation area, honeycomb holes can be more densely distributed, increasing the total area of ​​the holes and allowing heat to dissipate more effectively.

[0040] Meanwhile, the honeycomb-shaped edges and heat dissipation holes can evenly distribute the external force on the panel 10 throughout the entire structure. When the panel 10 is subjected to external pressure, impact, or vibration, this structure can support each other through multiple hexagonal holes, thereby enhancing the panel 10's resistance to pressure and deformation.

[0041] Therefore, panel 10 can maintain its own good structural strength while ensuring sufficient opening area for heat dissipation.

[0042] Furthermore, a reinforcing region 12 is provided on the outer periphery of the heat dissipation area 11, and two adjacent heat dissipation areas 11 are connected through the reinforcing region 12.

[0043] Specifically, the reinforced area 12 is the area on the panel 10 without heat dissipation holes. Its material is evenly and continuously distributed, and it can evenly bear and disperse external forces. Since the reinforced area 12 is located on the outer periphery of the heat dissipation area 11, when the material around the heat dissipation holes is repeatedly subjected to stresses such as thermal expansion and contraction and slight external impacts, the reinforced area 12 can effectively block the transmission of these stresses to the edge of the panel 10, and avoid the problem of reduced edge strength of the panel 10 leading to a decrease in the connection strength between the connector and the main unit casing.

[0044] In addition, the outer edge of the heat dissipation area 11 can be thickened to form a reinforced area 12. This thickening can be uniform or gradual. For example, the thickness can be gradually increased near the edge of the heat dissipation area 11, and then gradually return to normal thickness further away from the edge.

[0045] The thickened frame increases the strength of the panel 10 at its edges by providing more material to withstand external pressure. In areas where stress concentration is likely to occur at the edges of the heat dissipation area 11, the thickened frame acts as a robust protective layer, effectively resisting cracks and deformations that may result from stress concentration.

[0046] In this way, the reinforcing zone 12 provided around the heat dissipation zone 11 can effectively solve the problem of reduced strength of the panel 10 caused by the heat dissipation zone 11. When the panel 10 is subjected to external pressure, the reinforcing zone 12 can disperse stress concentration. Due to the presence of the heat dissipation zone 11, stress concentration is prone to occur, especially at the edges of structures such as heat dissipation holes. The reinforcing zone 12 acts as a buffer, distributing stress evenly across the entire panel 10.

[0047] Furthermore, the panel 10 has a heat dissipation surface, and the two sides of the panel 10 extend in a direction away from the heat dissipation surface to form a connecting side plate 13, and the heat dissipation area 11 extends from the panel 10 to the connecting side plate 13.

[0048] It should be noted that when the panel 10 is installed with the main unit case, it is connected to the main unit case via the connecting side panel 13. The heat dissipation surface is the large surface of the panel 10 that is furthest from the main unit case after it is installed.

[0049] In this design, the heat dissipation area 11 of panel 10 extends from panel 10 to connecting side panel 13, effectively expanding the heat dissipation area. When air flows through the heat dissipation area 11 of panel 10, the connecting side panel 13 also participates in heat dissipation, changing the direction and speed of airflow and creating a more complex and effective convection pattern. For example, air can enter along the heat dissipation area 11 on the front of panel 10, then carry heat out through the heat dissipation area 11 of connecting side panel 13, or vice versa. This convection method can make fuller use of air to remove heat, further enhancing the heat dissipation effect.

[0050] Further, see Figure 3 The ends of the connecting side plate 13 extend inward to form a first side flange 131 and a second side flange 132, wherein the first side flange 131 is provided with a first connector and the second side flange 132 is provided with a second connector, and both the first connector and the second connector are used to connect to the main unit housing.

[0051] Based on this structure, when installing the panel 10 onto the main unit housing, firstly, the panel 10 is placed in a suitable position so that the first side flange 131 and the second side flange 132 at the end of the connecting side panel 13 are close to and abut against the corresponding connection parts of the main unit housing. Then, the panel 10 is connected to the main unit housing through the first connector on the first side flange 131 and the second connector on the second side flange 132.

[0052] During the operation of the heat pump unit, the panel 10 is firmly connected to both sides of the unit casing via the first and second connectors, maintaining its normal position. At the same time, the heat dissipation area 11 on the panel 10 performs heat dissipation, while the connection structure ensures that the panel 10 will not loosen or shift due to vibration of the unit or other external forces, ensuring the stability of the heat dissipation function.

[0053] The first side flange 131 and the second side flange 132 provide precise positioning for the installation of the panel 10. When the panel 10 is installed into the main unit housing, the side flanges can fit tightly against the edge of the main unit housing, allowing the panel 10 to be accurately installed in the predetermined position.

[0054] Further, see Figure 4 The two ends of the panel 10 extend away from the heat dissipation surface to form connecting end plates 14, and the two connecting end plates 14 are respectively provided with a third connector 141 and a fourth connector. The first connector, the second connector, the third connector 141 and the fourth connector are formed as connecting parts.

[0055] Based on this structure, when installing panel 10, the side flanges with the first and second connectors are first preliminarily aligned with the corresponding positions on the main unit housing to initially position both sides of panel 10. Next, the third connector 141 and the fourth connector on the two connecting end plates 14 are connected to the corresponding connection points on the main unit housing.

[0056] During the operation of the heat pump unit, the panel 10 is securely fixed to the unit casing via the connecting parts formed by the first, second, third, and fourth connecting components. At this time, the heat dissipation area 11 of the panel 10 works normally, dissipating the heat generated inside the unit. The connecting parts can resist the influence of vibration, thermal expansion and contraction and other factors generated during the operation of the unit on the position of the panel 10, ensuring the stability of the panel 10 and that the heat dissipation function is not interfered with.

[0057] Thus, the four connectors tightly connect the panel 10 to the main housing from multiple directions. This omnidirectional connection greatly enhances the stability of the connection between the panel 10 and the main housing. Compared to connections made only on both sides or in certain locations, this multi-point connection can better cope with various complex external forces.

[0058] Further, see Figure 3 The first connector includes a connecting plate 135. Specifically, the connecting plate 135 extends from the end of the first side flange 131 in a direction away from the heat dissipation surface. A connecting groove 136 is provided at the connection point between the connecting plate 135 and the first side flange 131, and a connecting hole 15 is also provided on the connecting plate 135. (See reference...) Figure 5 The second connector includes a hook 134, and one end of the hook 134 is connected to the second side flange 132.

[0059] Based on this structure, during connection, first align the first side flange 131 with the first connector and the second side flange 132 with the second connector on the panel 10 with the corresponding mounting positions on the main unit housing. For the connecting plate 135 in the first connector, align the connecting slot 136 at its end with the matching protrusion (such as a locking block) on the main unit housing, and then gently push the panel 10 so that the connecting slot 136 engages with the corresponding protrusion, achieving initial positioning and a certain degree of connection fixation. This ensures that the lateral position of the panel 10 on this side is relatively stable and prevents left and right wobbling.

[0060] Next, by using the connection holes 15 provided on the connecting plate 135, fasteners such as bolts or pins are inserted and tightened to the corresponding screw holes on the main housing to further strengthen the connection on this side, so that the first side flange 131 is tightly connected to the main housing.

[0061] For the hook 134 of the second side flange 132, hook it onto the corresponding hook part or the edge of the slot 136 on the main body shell, so that the hook 134 and the main body shell form an effective snap connection, thereby fixing the side where the second side flange 132 is located, restricting the movement of the panel 10 in this direction, and cooperating with the connection of the first side flange 131 to constrain the panel 10 from both sides, ensuring that the panel 10 is stably installed on the main body shell in the horizontal direction.

[0062] Thus, the connecting plate 135 of the first connector is engaged and positioned with the main housing through the connecting slot 136, and further fastened by the connecting hole 15. The hook 134 of the second connector is connected to the main housing through a snap-fit ​​method. The two work together to fix the panel 10 from both sides, forming a stable and reliable connection structure.

[0063] Further, see Figure 3 and Figure 4 One of the connecting end plates 14 extends inward to form an end flange 142. The third connecting member 141 includes a connecting plate segment 143 and an abutting plate segment 144. The two ends of the connecting plate segment 143 are respectively connected to one end of the end flange 142 and one end of the abutting plate segment 144. The abutting plate segment 144 is disposed opposite to the end flange 142 and a locking gap 145 is formed between them. In addition, the end flange 142 is provided with a positioning hole 16 and a slot 136.

[0064] Based on this structure, when installing panel 10, first move panel 10 to a mounting position close to the main unit housing, aligning the connecting end plate 14 with the third connector 141 with the corresponding mounting part on the main unit housing. Then, align the positioning hole 16 on the end flange 142 with the corresponding positioning post or other positioning structure on the main unit housing and insert it, thereby initially fixing the position of the connecting end plate 14 on the main unit housing and playing a certain positioning role.

[0065] Then, utilizing the snap-fit ​​interval 145 formed between the abutment plate segment 144 and the end flange 142 in the third connector 141, the corresponding snap-fit ​​structure on the main housing (such as a protruding snap block) is inserted into this snap-fit ​​interval 145, so that the abutment plate segment 144 and the end flange 142 abut against both sides of the snap-fit ​​structure, achieving a snap-fit ​​engagement. At the same time, the slot 136 on the end flange 142 can also engage with the corresponding snap tongue or other structure on the main housing, further enhancing the stability of the connection.

[0066] Furthermore, the fourth connector includes a mounting plate 146. Specifically, one end of the mounting plate 146 is connected to the end of another connecting end plate 14, the other end of the mounting plate 146 extends away from the connecting end plate 14, and the mounting plate 146 is provided with a connection hole 15.

[0067] Based on this structure, the connection holes 15 on the mounting plate 146 can be aligned with the corresponding mounting holes on the main unit housing, and then screws or pins can be used to connect them.

[0068] Thus, the third connector 141 and the fourth connector work together to firmly connect the two ends of the panel 10 to the main unit housing, which can effectively resist the influence of external forces such as vibration and shaking generated during the operation of the main unit, ensuring that the panel 10 remains stable on the main unit housing for a long time and will not loosen, shift or even fall off due to frequent external forces, thus ensuring the stability of the connection between the panel 10 and the main unit housing.

[0069] Example 2

[0070] Unlike Embodiment 1, this embodiment discloses a heat pump host, which includes the housing assembly of Embodiment 1. Specifically, the host housing has a mounting cavity with a mounting port. The compressor, condenser, and other components of the heat pump host are installed in the mounting cavity through the mounting port, and then the panel 10 covers the mounting port.

[0071] During operation, the heat generated by components such as the compressor and condenser can be dissipated to the external environment through the heat dissipation area 11 on the panel 10. Since the edge shape of the heat dissipation area 11 is the same as the shape of the heat dissipation holes, the heat dissipation holes can be more densely distributed within the heat dissipation area 11, allowing the heat dissipation area 11 to utilize a larger number of heat dissipation holes within its effective area, thereby increasing the heat dissipation area of ​​the heat dissipation area 11. Simultaneously, heat dissipation holes can be created without occupying other areas of the panel 10.

[0072] The specific structure of panel 10 and the function of heat dissipation area 11 are described in detail in Embodiment 1, and will not be elaborated further here.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
