Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically to a cabinet air conditioner and a container assembly. Background Technology

[0002] The increasing scarcity of traditional energy sources and the worsening environmental situation have greatly promoted the development of new energy sources. Energy storage has become particularly important, with containerized energy storage being a major form of electrochemical energy storage. The container consists of lithium battery packs, battery racks, ventilation ducts, and a control system. During charging and discharging, the batteries generate heat, necessitating cooling of the internal space of the energy storage container. Simultaneously, the market for small data centers and data center cooling is also growing rapidly.

[0003] Conventional fan cooling systems have poor heat dissipation performance and easily bring dust, moisture, and other gaseous impurities from the outside air into the server rack. Containerized energy storage and small data centers require dedicated air conditioning to control the temperature within the enclosed battery compartments or server room spaces. Temperature has a significant impact on battery safety and lifespan; similarly, data centers within server rooms also require excellent temperature control. Integrated rack-mount air conditioners are single units that can be directly installed on the container or door of an energy storage cabinet, either recessed or wall-mounted. Integrating the indoor and outdoor units offers advantages such as ease of installation and small footprint. However, these wall-mounted integrated rack-mount air conditioners, because they are hung on the door, suffer significant air loss along the way when delivering air into the container's batteries, affecting the airflow to batteries further away. Top-mounted energy storage air conditioners, located on the top of the energy storage container, deliver downward airflow evenly to the battery racks, offering the advantage of uniform air distribution.

[0004] Currently, because energy storage container air conditioners are located on top of the container, the overall unit has high requirements for rain and snow protection. It is necessary to ensure that no water can seep into the container through the indoor air supply and return vents, which could lead to safety hazards such as water damage to the batteries.

[0005] Because existing top-mounted integrated cabinet air conditioners have poor waterproof performance, which makes the inside of the top-mounted air conditioner easy to get water in, causing safety hazards, this invention studies and designs a cabinet air conditioner and container component. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the defect of poor waterproof performance of the existing top-mounted integrated cabinet air conditioner, which makes the inside of the top-mounted air conditioner easy to be flooded and cause safety hazards, thereby providing a cabinet air conditioner and container component.

[0007] To address the above problems, the present invention provides a cabinet air conditioner, comprising:

[0008] An indoor chassis, an outdoor chassis, and a chassis frame assembly are provided. The chassis frame assembly includes a central crossbeam.

[0015] In some embodiments, a partition shell is also included, on which an evaporator and an indoor fan are disposed. The partition shell has a structure with an internal cavity and is connected to the indoor chassis and covers the outer periphery of the evaporator and the indoor fan.

[0016] In some embodiments, the indoor side chassis is provided with a return air inlet and a supply air inlet. The return air inlet can draw in air from the room and enter the internal cavity of the partition shell. The supply air inlet can send the air in the internal cavity, after heat exchange with the evaporator, into the room. The return air inlet is located on one side of the evaporator, and the supply air inlet is located on the other side of the evaporator.

[0017] In some embodiments, the indoor fan is located on the side of the evaporator facing the air outlet, and the indoor fan has a fan outlet that is opposite to the air outlet.

[0018] In some embodiments, a first protrusion protruding upward is provided on the indoor side chassis and located on the outer periphery of the return air inlet, and a second protrusion protruding upward is provided on the indoor side chassis and located on the outer periphery of the supply air inlet.

[0019] In some embodiments, when the interior side chassis includes a first hook:

[0020] The partition housing includes a cover body and a bottom surface. The bottom surface is connected to the lower edge of the cover body and is attached to the upper surface of the first hook on the indoor side chassis. The bottom surface and the upper surface of the first hook are fastened together by threaded fasteners.

[0022] In some embodiments, the partition shell is an integrally formed structure, and the partition shell is made of waterproof material or the surface of the partition shell is sprayed with waterproof material to form an integral waterproof partition shell.

[0023] In some embodiments, the partition shell is integrally formed by a sheet metal mold, or the partition shell is processed by welding multiple sheet metal parts together and then powder coating.

[0024] In some embodiments, when the cabinet air conditioner further includes a first panel, a second panel, a first side panel, a second side panel, and a top cover, and the top cover is provided with an air inlet:

[0025] The cabinet air conditioner also includes an electrical box, which is disposed on the indoor side chassis and located outside the partition housing. The partition housing also has an inclined surface, and the air inlet is located above the inclined surface so that the outdoor air drawn in from the air inlet is located outside the partition housing.

[0026] The present invention also provides a container assembly comprising a container and a cabinet air conditioner as described in any of the preceding claims, the cabinet air conditioner being connected to the container to cool or heat the interior of the container.

[0027] In some embodiments, when the indoor side chassis is provided with a return air vent and a supply air vent, and the indoor side chassis has a first upwardly protruding portion located on the outer periphery of the return air vent, and the indoor side chassis has a second upwardly protruding portion located on the outer periphery of the supply air vent:

[0028] The air conditioner cabinet is installed on the top of the container. The top of the container is provided with an upwardly protruding return air vent flange and an upwardly protruding air inlet flange. The return air vent flange can be inserted upward into the return air vent to form a plug-in fit with the first protrusion. The air inlet flange can be inserted upward into the air supply vent to form a plug-in fit with the second protrusion.

[0029] The cabinet air conditioner and container assembly provided by this invention have the following beneficial effects:

[0030] 1. This invention establishes independent and separate indoor and outdoor chassis structures, effectively creating an opening structure within the chassis frame to accommodate both the indoor and outdoor chassis. A central crossbeam further divides this opening structure into a first opening and a second opening. The first opening accommodates the indoor chassis, and the second opening accommodates the outdoor chassis. This effectively separates and secures the indoor and outdoor chassis, preventing water from the outdoor unit from entering the indoor unit, thus improving the waterproof performance of the cabinet air conditioner and avoiding [further problems]. The water ingress prevention of the indoor chassis further enhances the waterproof performance of the interior (preferably the container interior), improving safety. Furthermore, the invention utilizes a first hook at the upper end of the indoor chassis to form a folded edge and hook onto the chassis frame assembly, further enhancing the waterproof performance of the interior chassis and preventing water from entering the interior (preferably the container interior). Additionally, the invention employs a second hook at the upper end of the outdoor chassis to form a folded edge and hook onto the chassis frame assembly, further preventing outdoor water from entering the interior chassis, thus further improving the waterproof and sealing performance of the interior.

[0031] 2. The present invention also effectively forms a waterproof cover structure through the partition shell, enclosing the components on the indoor chassis inside it, forming an independent sealed cavity together with the indoor chassis, isolating it from the outdoor side, and further improving the waterproof performance of the indoor side (preferably the container interior); furthermore, by attaching the bottom surface of the partition shell to the first hook of the indoor chassis and fastening it with threaded fasteners, the waterproof and sealing performance of the interior of the partition shell (i.e., the indoor chassis) can be further enhanced, further improving the waterproof performance of the indoor side (preferably the container interior); the present invention also effectively wraps the first hook inside the downward extending folded edge of the partition shell, further enhancing the waterproof and sealing performance of the components (including evaporators, indoor fans, etc.) on the indoor chassis, further improving the waterproof performance of the indoor side (preferably the container interior).

[0032] 3. The present invention also provides an upwardly protruding first protrusion on the outer periphery of the return air inlet and a downwardly protruding second protrusion on the outer periphery of the air supply inlet on the indoor side chassis. This effectively raises the indoor side return air inlet and indoor side air supply inlet by a certain distance, thereby preventing water ingress caused by condensation formed at the return air inlet and air supply inlet entering the interior of the indoor side chassis. This further enhances the waterproof effect on the indoor side (preferably the interior of the container) and prevents water from accumulating on the chassis and entering the indoor side.

[0044] In the description of this invention, it should be noted that the terms "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0045] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "contact," and "communication" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] like Figure 1-6 As shown, the present invention also provides a cabinet air conditioner (preferably a top-mounted integrated container energy storage cabinet air conditioner), which includes:

[0047] The chassis includes an indoor chassis 20, an outdoor chassis 30, and a chassis frame assembly 10. The chassis frame assembly 10 includes a central crossbeam 13. The bottom of the chassis frame assembly 10 forms an opening structure 100. The central crossbeam 13 is disposed in the opening structure 100 to divide the opening structure 100 into a first opening 101 and a second opening 102. The indoor chassis 20 is disposed in the first opening 101 and connected to the chassis frame assembly 10. The outdoor chassis 30 is disposed in the second opening 102 and connected to the chassis frame assembly 10. The indoor chassis 20 and the outdoor chassis 30 are separated by the central crossbeam 13.

[0048] This invention sets the indoor and outdoor chassis as independent and separate structures, and effectively forms an opening structure through the chassis frame structure, which can accommodate both the indoor and outdoor chassis. Furthermore, the central crossbeam divides the opening structure into a first opening and a second opening. The first opening accommodates the indoor chassis, and the second opening accommodates the outdoor chassis. This effectively separates the indoor and outdoor chassis and allows for efficient installation and fixation, effectively preventing water from the outdoor side of the unit from entering the indoor side, improving the waterproof performance of the cabinet air conditioner, preventing water ingress into the indoor chassis, further improving the waterproof performance of the interior (preferably inside the container), and enhancing safety.

[0049] Currently, energy storage container air conditioners, located on top of the container, have high requirements for rain and snow protection. To ensure that water cannot seep into the container through the indoor air supply and return vents, posing safety hazards such as battery water damage, this invention proposes a top-mounted integrated cabinet air conditioner for battery energy storage containers.

[0050] This invention has three main aspects regarding waterproof design. First, the waterproof design uses an independent indoor and outdoor chassis design to prevent water from the outdoor side of the unit from entering the indoor side. Second, the waterproof design uses an integrated indoor rainproof shell design to form an independent, sealed cavity with the indoor chassis, isolating it from the outdoor side and achieving waterproofing. Third, the waterproof design uses a design that raises the indoor air inlet and outlet to prevent water from accumulating on the chassis from entering the indoor side, thereby comprehensively improving the waterproof capability of the roof-mounted air conditioner.

[0051] In some embodiments, the indoor chassis 20 includes a first hook 23 located at the edge of the indoor chassis 20 and extending upward, and bending outward and downward sequentially after reaching the top, so that the first hook 23 can be hooked onto the chassis frame assembly 10; the outdoor chassis 30 includes a second hook located at the edge of the outdoor chassis 30 and extending upward, and bending outward and downward sequentially after reaching the top, so that the second hook can be hooked onto the chassis frame assembly 10.

[0052] The present invention further improves the waterproof performance of the interior of the interior chassis by using a first hook at the upper end of the interior chassis to form a folded edge and hook onto the chassis frame assembly, thereby further preventing water from entering the interior (preferably the interior of a container); the present invention also improves the waterproof and sealing performance of the interior by using a second hook at the upper end of the exterior chassis to form a folded edge and hook onto the chassis frame assembly, thereby further preventing water from the exterior from entering the interior of the interior chassis.

[0053] In some embodiments, the chassis frame assembly 10 includes a first crossbeam 12, a second crossbeam 14, a first longitudinal beam 15, a second longitudinal beam 16, a first column 111, a second column 112, a third column 113, and a fourth column 114. The first crossbeam 12 and the second crossbeam 14 are spaced apart, and the first longitudinal beam 15 and the second longitudinal beam 16 are spaced apart. One end of the first crossbeam 12 is connected to one end of the first longitudinal beam 15 via the first column 111, and the other end of the first crossbeam 12 is connected to one end of the second longitudinal beam 16 via the second column 112. One end of the second crossbeam 14 is connected to the other end of the first longitudinal beam 15 via the third column 113, and the other end of the second crossbeam 14 is connected to the other end of the second longitudinal beam 16 via the fourth column 114.

[0054] The middle crossbeam 13 is located between the first crossbeam 12 and the second crossbeam 14, and one end of the middle crossbeam 13 is connected to the first longitudinal beam 15 and the other end is connected to the second longitudinal beam 16. The middle crossbeam 13, the first crossbeam 12, the first longitudinal beam 15 and the second longitudinal beam 16 form the first opening 101, and the middle crossbeam 13, the second crossbeam 14, the first longitudinal beam 15 and the second longitudinal beam 16 form the second opening 102.

[0055] This is a preferred structural form of the chassis frame assembly of the present invention. The first and second crossbeams, as well as the first and second longitudinal beams, which are spaced apart, can effectively form an opening structure in the middle. The columns are used to connect and fix the adjacent crossbeams and longitudinal beams, and the upper part of the columns is used to effectively connect with the side plates and the front panel to form the shell structure of the cabinet air conditioner. The middle crossbeam of the present invention is located between the first and second crossbeams to effectively divide the opening structure into a first opening and a second opening. The first opening is used to accommodate the indoor chassis, and the second opening is used to effectively accommodate the outdoor chassis, forming a separate and independent structure for the indoor and outdoor chassis, which effectively improves the waterproof performance of the interior of the indoor chassis.

[0056] In some embodiments, the system further includes a first panel 4, a second panel 1, a first side panel 2, a second side panel 3, and a top cover 5. The chassis frame assembly 10 is connected to the first panel 4, the second panel 1, the first side panel 2, the second side panel 3, and the top cover 5, and together they form a hollow cavity. The first panel 4 is connected to the second crossbeam 14, the third column 113, and the fourth column 114, respectively. The second panel 1 is connected to the first crossbeam 12, the first column 111, and the second column 112, respectively. The first side panel 2 is connected to the second longitudinal beam 16, the second column 112, and the fourth column 114, respectively. The second side panel 3 is connected to the first longitudinal beam 15, the first column 111, and the third column 113, respectively.

[0057] This is a further preferred structural form of the cabinet air conditioner of the present invention. Through the structure of the first and second panels, the first and second side panels and the top cover, it can be effectively connected with the chassis frame assembly at the lower end to form a shell structure with a hollow cavity. The function of the column is to connect the adjacent side panels and the panel. The lower part of the column connects the crossbeam and the longitudinal beam to form an integrated shell structure of the cabinet air conditioner.

[0058] like Figure 1 The image shown is an external view of the top-mounted integrated containerized energy storage unit air conditioner of this invention. The outdoor side of the unit has top and side air intakes and a front door panel air outlet, while the indoor side features a bottom air supply and return design. The indoor and outdoor sides are separated by a partition. Figure 1 As shown in Figure 3, the unit forms an indoor cavity and an outdoor cavity through a chassis frame assembly 10, an indoor chassis 20, an outdoor chassis 30, a partition shell 40 (preferably an integrated waterproof shell partition), an electrical box 50, a second panel 1 (i.e., a rear panel), a first side panel 2 (i.e., a left side panel), a second side panel 3 (i.e., a right side panel), a first panel 4 (i.e., a front panel), and a top cover 5.

[0059] The present invention uses a chassis frame assembly 10 to support the indoor chassis 20 and the outdoor chassis 30, such as... Figures 3a-3b The diagram shows the air conditioner chassis frame assembly of the present invention and its assembly with the independent indoor and outdoor chassis. Compared to existing chassis frame designs, where the chassis is typically placed and fixed to the upper surface of the beam structure of the chassis frame, the present invention uses a chassis embedded in the chassis frame assembly 10 to maximize the use of the overall unit space, utilizing the space in the height direction of the frame beams. To achieve an independent indoor and outdoor chassis design, the present invention designs a chassis frame assembly 10 that is compatible with it. The chassis frame assembly 10 forms two regions (i.e., the first opening and the second opening) on ​​the indoor and outdoor sides through the first crossbeam 12 (i.e., the rear crossbeam), the middle crossbeam 13, the second crossbeam 14 (i.e., the front crossbeam), the first longitudinal beam 15 (i.e., the right longitudinal beam), and the second longitudinal beam 16 (i.e., the left longitudinal beam). This allows the indoor chassis 20 to be embedded in the first opening, and the outdoor chassis 30 to be embedded in the second opening. Figure 3a The image shows the chassis frame assembly 10 of the present invention, as shown. Figure 3b The diagram shown is a schematic of the chassis frame assembly 10 of the present invention after being assembled with the inner and outer independent chassis. This design prevents water from the outdoor side of the unit from entering the indoor side.

[0060] In some embodiments, the first column 111 extends vertically upward, with its lower portion connected to the first crossbeam 12 and the first longitudinal beam 15, and its upper portion connected to the second side plate 3 and the second front panel 1; the second column 112 extends vertically upward, with its lower portion connected to the first crossbeam 12 and the second longitudinal beam 16, and its upper portion connected to the first side plate 2 and the second front panel 1. The third column 113 extends vertically upwards, with its lower part connected to the second crossbeam 14 and the first longitudinal beam 15, and its upper part connected to the second side plate 3 and the first front panel 4, respectively. The fourth column 114 extends vertically upwards, with its lower part connected to the second crossbeam 14 and the second longitudinal beam 16, and its upper part connected to the first side plate 2 and the first front panel 4, respectively.

[0061] The lower part of the four columns of this invention is used to connect adjacent crossbeams and longitudinal beams, and the upper part is used to connect adjacent side plates and panels, realizing a structure that effectively connects the panels, side plates, top cover and chassis frame assembly into one unit. It can also realize a separate and independent structure for the indoor chassis and the outdoor chassis, effectively enhancing and improving the waterproof and sealing effect of the indoor chassis, and improving the safety performance of the indoor side.

[0062] In some embodiments, the outdoor chassis 30 is provided with a compressor 60, a condenser 8 and an outdoor fan 9, the top cover 5 is provided with an air inlet 51, the first panel 4 is provided with an air outlet 91, and the outdoor fan 9 can drive outdoor air to enter the hollow cavity through the air inlet 51 and exchange heat with the condenser 8, and finally blow it out through the air outlet 91.

[0063] The present invention has a structure on the outdoor side chassis with a compressor, a condenser and an outdoor fan. The top cover is provided with an air inlet and the first panel is provided with an air outlet, so that outdoor air enters the cabinet air conditioner through the air inlet and exchanges heat with the condenser, and the air after heat exchange is blown out through the air outlet.

[0064] In some embodiments, a partition shell 40 is also included. An evaporator 6 and an indoor fan 7 are mounted on the indoor chassis 20. The partition shell 40 has an internal cavity structure and is connected to the indoor chassis 20, covering the outer periphery of the evaporator 6 and the indoor fan 7. The present invention also effectively forms a waterproof cover structure by using the partition shell, enclosing the components on the indoor chassis within it. Together with the indoor chassis, they form an independent, sealed cavity, isolating the exterior from the exterior, further improving the waterproof performance of the interior (preferably the container interior).

[0065] In some embodiments, the indoor chassis 20 is provided with a return air inlet 21 and an air supply inlet 22. The return air inlet 21 draws in air from the room and enters the internal cavity of the partition shell 40. The air supply inlet 22 delivers air from the internal cavity, after heat exchange with the evaporator 6, into the room. The return air inlet 21 is located on one side of the evaporator 6, and the air supply inlet 22 is located on the other side of the evaporator 6. This invention, through the return air inlet and air supply inlet provided on the indoor chassis, can draw indoor air (preferably air from inside the container) into the interior of the partition shell through the return air inlet and exchange heat with the evaporator. The heat-exchanged air is then delivered back into the room (preferably inside the container) through the air supply inlet.

[0066] Preferably, the indoor chassis 20 also includes a return air inlet 21, an air supply outlet 22, and an indoor fan mounting platform; the outdoor chassis 30 has an outdoor fan assembly and compressor mounting platform, and may also include several drainage holes.

[0067] like Figure 6 As shown, the air supply principle diagram of the air conditioner of the present invention is as follows: Figure 2A cross-sectional view along direction AA. The arrows indicate the direction of airflow. It can be seen that for the outdoor unit, air enters through the mesh or louvered structures on the top and sides of the diagram, passes through the condenser 8, and is exhausted to the outside of the unit by the outdoor fan 9. For the indoor side, the indoor fan 7 (centrifugal fan) draws indoor air from inside the container into the indoor cavity through the return air inlet 21 on the indoor chassis 20, passes through the evaporator 6, and is then sent into the container through the air outlet 22.

[0068] The present invention, through the above-mentioned independent indoor and outdoor chassis design, can effectively prevent water from the outdoor side of the unit from entering the indoor side.

[0069] In some embodiments, the indoor fan 7 is disposed on the side of the evaporator 6 facing the air outlet 22. The indoor fan 7 has a fan outlet, which is disposed opposite to the air outlet 22. This is the preferred placement of the indoor fan of the present invention. By placing it on the side of the evaporator facing the air outlet, it can draw in air from the side of the evaporator facing the return air outlet by suction, exchange heat with the evaporator, and then blow the air out of the air outlet into the room (preferably inside the container) through the indoor fan.

[0070] In some embodiments, a first protrusion 24 protruding upward is provided on the indoor side chassis 20 and located on the outer periphery of the return air vent 21, and a second protrusion 25 protruding upward is provided on the indoor side chassis 20 and located on the outer periphery of the supply air vent 22.

[0071] The present invention also provides an upwardly protruding first protrusion on the outer periphery of the return air inlet and a downwardly protruding second protrusion on the outer periphery of the air supply inlet on the indoor side chassis. This effectively raises the indoor side return air inlet and indoor side air supply inlet by a certain distance, thereby preventing water ingress caused by condensation formed at the return air inlet and air supply inlet entering the interior of the indoor side chassis. This further enhances the waterproof effect on the indoor side (preferably the interior of the container) and prevents water from accumulating on the chassis and entering the indoor side.

[0072] In some embodiments, when the indoor side chassis 20 includes a first hook 23:

[0073] The partition shell 40 includes a main body and a bottom surface 43. The bottom surface 43 is connected to the lower edge of the main body and is fitted against the upper surface of the first hook 23 on the indoor chassis 20. The bottom surface 43 and the upper surface of the first hook 23 are fastened together by threaded fasteners. Furthermore, by fitting the bottom surface of the partition shell against the first hook of the indoor chassis and fastening it with threaded fasteners, this invention further enhances the waterproofing and sealing performance of the interior of the partition shell (i.e., the indoor chassis), and further improves the waterproofing performance of the interior (preferably the interior of a container).

[0074] like Figure 4a , 4b and Figure 5 The diagram shows the assembly of the integrated waterproof housing partition (partition housing 40) of the air conditioner of the present invention with the indoor chassis 20. The integrated waterproof housing partition acts as a waterproof cover and has a bottom surface 43 that cooperates with the first hook 23 of the indoor chassis 20.

[0075] Preferably, the bottom surface 43 of the partition shell 40 has several matching screw holes at the mating point with the first hook 23 of the indoor chassis 20, so that the integrated waterproof partition shell 40 is completely sealed on the chassis by screws to form a closed indoor cavity.

[0076] In some embodiments, the partition housing 40 further includes a lower folded edge 41, the upper end of which is connected to the bottom surface 43, and the lower end extends downward to enclose the first hook 23 on the inside. The present invention also effectively encloses the first hook on the inside by means of the downwardly extending lower folded edge of the partition housing, which further enhances the waterproofing and sealing performance of components on the indoor chassis (including evaporators, indoor fans, etc.), and further improves the waterproofing performance of the indoor side (preferably the interior of the container).

[0077] The partition shell of the present invention also has an outwardly extending bottom surface 43, and the indoor chassis has a first hook 23. The upper end surface of the first hook mates with the bottom surface 43, so that the screw hole is on the outside of the indoor chassis 20, preventing water from flowing into the inside of the indoor chassis 20 from the mounting screw hole. Furthermore, the partition shell of the present invention also has a downwardly extending lower folded edge 41 that covers the indoor chassis 20. The indoor chassis 20 has an outwardly folded edge forming a mounting surface, which allows rainwater to flow down from the outer surface of the partition shell 40 to the outside of the indoor chassis 20 through the lower folded edge 41, further enhancing the waterproof performance of the indoor side.

[0078] In some embodiments, the partition shell 40 is a one-piece molded structure, and the partition shell 40 is made of waterproof material or the surface of the partition shell is sprayed with waterproof material to form an integrated waterproof partition shell. This is a preferred structural form of the partition shell of the present invention. As a one-piece molded structure, it can further improve the waterproof and sealing effect on the inside and outside, preventing external water from entering the interior. The partition shell is further made of waterproof material, which can further enhance its waterproof performance.

[0079] In some embodiments, the partition shell 40 is integrally formed using a sheet metal integrated mold, or the partition shell 40 is processed by welding multiple sheet metal parts together and then powder coating. This invention effectively achieves waterproofing of the parts by using an integrated waterproof partition shell 40 formed by a sheet metal integrated mold or by other methods such as full welding followed by powder coating.

[0080] Preferably, apart from the screw holes at the mating points with the chassis, the integrated waterproof housing partition has no screw holes, rivet holes, or other structures that are detrimental to waterproofing.

[0081] The present invention achieves waterproofing by using an integrated indoor rainproof shell design (i.e., partition shell 40) to form an independent sealed cavity with the indoor chassis, which is isolated from the outdoor side. This is the second waterproof design feature of the present invention.

[0082] In some embodiments, when the cabinet air conditioner further includes a first panel 4, a second panel 1, a first side panel 2, a second side panel 3, and a top cover 5, and the top cover 5 is provided with an air inlet 51:

[0083] The cabinet air conditioner also includes an electrical box 50, which is disposed on the indoor side chassis 20. The electrical box 50 is located outside the partition housing 40. The partition housing 40 also has an inclined surface 42 (an inclined surface is an inclined surface with an angle between 0 and 90° with respect to the horizontal plane). The air inlet 51 is located above the inclined surface 42 so that the outdoor air drawn in from the air inlet 51 is located outside the partition housing 40.

[0084] This is the preferred location for the electrical box of the present invention. Placing it outside the partition shell can effectively prevent condensate formed by the evaporator inside the partition shell from corroding the electrical box and causing safety issues. The inclined surface of the partition shell can act as a guide, directing outdoor air to the condenser and air outlet. Placing the electrical box on the indoor chassis, relatively far from the outdoor chassis, can also effectively prevent the heat released by the condenser on the outdoor chassis from affecting the heat dissipation performance of the electrical box, thereby improving the heat dissipation performance and safety performance of the electrical box.

[0085] The present invention also provides a container assembly comprising a container and the aforementioned cabinet air conditioner, the cabinet air conditioner being connected to the container to cool or heat the interior of the container.

[0086] The container assembly of this invention, by employing an independent indoor and outdoor chassis design for the air conditioning unit, effectively prevents water from the outdoor side of the unit from entering the indoor side, thus effectively avoiding water ingress into the container and improving its internal waterproof performance. This invention further enhances waterproofing and sealing by providing a first hook on the indoor chassis and a second hook on the outdoor chassis. The integrated indoor waterproof cover design forms an independent, sealed cavity with the indoor chassis, isolating it from the outdoor side and further enhancing waterproofing performance. Furthermore, the first and second protrusions on the indoor chassis effectively raise the indoor air inlet and outlet, preventing water accumulation on the chassis from entering the indoor side and further enhancing waterproofing performance.

[0087] In some embodiments, when the indoor side chassis 20 is provided with a return air inlet 21 and an air supply inlet 22, and the indoor side chassis 20 has an upwardly protruding first protrusion 24 located on the outer periphery of the return air inlet 21, and the indoor side chassis 20 has an upwardly protruding second protrusion 25 located on the outer periphery of the air supply inlet 22:

[0088] The cabinet air conditioner is installed on the top of the container. The top of the container is provided with an upwardly protruding return air vent flange and an upwardly protruding air inlet flange. The return air vent flange can be inserted upward into the return air vent 21 to form a plug-in engagement with the first protrusion 24. The air inlet flange can be inserted upward into the air supply vent 22 to form a plug-in engagement with the second protrusion 25.

[0089] The present invention also utilizes a return air vent flange that is fitted on the container and mates with the return air vent, allowing the return air vent flange to be inserted into the return air vent, thereby raising and increasing the waterproof path and further improving the waterproof performance inside the container; and also utilizes an air supply vent flange that is fitted on the container and mates with the air supply vent, allowing the air supply vent flange to be inserted into the air supply vent, thereby raising and increasing the waterproof path and further improving the waterproof performance inside the container.

[0090] like Figure 6 As shown, the air supply and return vents on the unit chassis have a concave design when viewed from the bottom upwards, meaning the indoor air vents are raised relative to the bottom of the chassis. Figure 6 In the design, the return air vent is raised to height a, and the supply air vent is raised to height b. The top of the container is equipped with flanges that raise the vents to the corresponding heights. The return air vent flange and the supply air vent flange on the top of the container are embedded in the air vents at the bottom of the unit. By raising the indoor air vents and return air vents, water accumulation on the chassis is prevented from entering the indoor side through the air vents, thereby comprehensively improving the waterproof capability of the roof-mounted air conditioner.

[0091] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
