Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning technology, and in particular to an integrated cabinet air conditioner. Background Technology
[0002] In the field of air conditioning technology, integrated cabinet air conditioners play an important role in various scenarios, such as battery cabinets, outdoor cabinets, electrochemical energy storage cabinets, energy storage power stations, outdoor power cabinets, prefabricated power modules, control cabinets, and industrial equipment. Integrated cabinet air conditioners help solve the heat dissipation problems of high-density equipment through efficient heat dissipation, while also saving space.
[0003] like Figure 1 As shown, existing integrated rack-mount air conditioners use a design where the evaporator and condenser are installed on the front and rear sides of the rack, respectively, with a partition 1' separating them diagonally. However, this layout results in uneven airflow distribution, with lower airflow near the corner of the partition, leading to uneven airflow onto the evaporator and condenser surfaces. This airflow difference causes inconsistent flow path temperatures at both ends of the two units, affecting the evaporation and condensation of the refrigerant. For example, areas with high airflow on the rack surface experience more complete refrigerant evaporation, while areas with low airflow experience insufficient evaporation, resulting in uneven superheat. If the superheat in some areas is too low (close to zero or even with liquid refrigerant), it may cause the compressor to draw in wet vapor, or even liquid refrigerant to cause liquid slugging in the compressor, seriously threatening equipment safety.

[0042] like Figure 1 As shown, existing integrated rack-mount air conditioners use a design where the rack and condenser are installed on the front and back sides of the rack, respectively, with a partition 1' separating them diagonally. However, this layout results in uneven airflow distribution, with lower airflow near the corner of the partition, leading to uneven airflow across the rack and condenser surfaces. This airflow difference causes inconsistent flow path temperatures at both ends of the two units, affecting the evaporation and condensation of the refrigerant. For example, areas with high airflow on the rack surface experience more complete refrigerant evaporation, while areas with low airflow experience insufficient evaporation, resulting in uneven superheat. If the superheat in some areas is too low (close to zero or even with liquid refrigerant), it may cause the compressor to draw in wet vapor, or even liquid refrigerant to cause liquid slugging in the compressor, seriously threatening equipment safety.
[0043] Based on this, the following embodiments are proposed:
[0044] Example 1
[0045] like Figure 1-3 As shown, this embodiment provides an integrated cabinet air conditioner, including:
[0046] Cabinet 1, wherein the cabinet 1 has a cabinet cavity 101;
[0047] The first partition plate group 201 is installed inside the cabinet cavity 101, and the first partition plate group 201 and the cabinet 1 enclose a condensation area located at the top.
[0048] Condenser 202 is installed on the first partition plate assembly 201;
[0049] The cabinet 1 is provided with a first air inlet 1011 and a first air outlet 1012 that communicate with the cabinet cavity 101, corresponding to the condensation area. The first air inlet 1011 is located on the periphery of the condensation area, and the first air outlet 1012 is located on the top side of the condensation area.
[0050] In this embodiment, by setting a first partition plate group 201 in the upper part of the cabinet cavity 101 of the cabinet 1, the air duct structure for airflow in the cabinet cavity 101 is optimized. The integrated cabinet is vertically divided into upper and lower parts. A condensation area is formed in the upper part of the cabinet cavity 101, and the remaining part forms an evaporation area. The two areas are relatively independent. The upper area, i.e., the condensation area, mainly houses key components such as condensers, external fans, and compressors, while the evaporation area is equipped with components such as evaporators and water trays. The two are physically isolated by a partition. This partition design helps to clearly distinguish the condensation and evaporation processes, avoid mutual interference, and optimize space utilization.
[0051] The upper part of the cabinet cavity 101 is divided into an external fan cavity and an internal fan cavity by a first partition plate group 201. The external fan cavity occupies most of the space, while the internal fan cavity, although smaller, is connected to the lower part of the cabinet, together forming a complete internal fan cavity. An internal fan is installed on the inner panel at the upper part of the internal fan cavity. The internal fan promptly extracts the gas passing through the evaporator and exhausts it outside the cabinet. The optimized air duct design makes the air velocity through the condenser and evaporator more uniform, ensuring that the heat removed by both is basically the same, avoiding local overheating or insufficient heat dissipation.
[0052] Maintaining a consistent evaporation state of the refrigerant in the evaporator not only facilitates system commissioning and operation but also ensures that the unit can achieve optimal performance.
[0053] The integrated cabinet design proposed in this embodiment optimizes the structure and layout of the two evaporators through the arrangement of partition panels, and also optimizes the air duct design, significantly improving the cooling cycle efficiency of the air conditioning system. This design performs excellently in improving heat dissipation efficiency and optimizing airflow, ensuring more efficient heat exchange between the evaporator and condenser while optimizing the airflow path.
[0054] The improved cooling efficiency of air conditioners not only reduces the load on the compressor but also lowers the overall energy consumption of the system, thereby reducing operating costs and avoiding energy waste. For example... Figure 1 As shown, in existing structures, improper duct design can lead to insufficient refrigerant evaporation in the evaporator flow path, causing liquid slugging and severely damaging the compressor. The integrated cabinet proposed in this embodiment ensures sufficient refrigerant evaporation in the evaporator, preventing liquid refrigerant from entering the compressor, thereby extending the compressor's lifespan and improving system reliability.
[0055] Furthermore, integrated cabinet air conditioners also include:
[0056] The second partition plate group 301 is installed inside the cabinet cavity 101 and is located in the evaporation area below the first partition plate group 201;
[0057] Evaporator 302 is installed on the second partition plate assembly 301;
[0058] The cabinet 1 is provided with a second air inlet 1013 and a second air outlet 1014 that communicate with the cabinet cavity 101, and the second air inlet 1013 is located on the lower side of the evaporation area, and the second air outlet 1014 is located on the upper side of the evaporation area.
[0059] In this embodiment, by setting a first partition plate group 201 at the upper part and a second partition plate group 301 at the lower part of the cabinet cavity 101 of the cabinet 1, the air duct structure for airflow within the cabinet cavity 101 is further optimized. The integrated cabinet is vertically divided into upper and lower parts. A condensation area is formed in the upper part of the cabinet cavity 101, and an evaporation area is formed in the remaining part of the cabinet cavity 101. The two areas are relatively independent. The upper area, i.e., the condensation area, mainly houses key components such as condensers, external fans, and compressors, while the lower area, i.e., part of the evaporation area, is equipped with components such as evaporators and water trays. The two are physically isolated by partitions. This partition design helps to clearly distinguish the condensation and evaporation processes, avoid mutual interference, and optimize space utilization.
[0060] By configuring the first partition plate group 201 and the second partition plate group 301, the structure and layout of the two heat exchangers are optimized, and the air duct design is also improved, significantly enhancing the refrigeration cycle efficiency of the air conditioning system. This design excels in improving heat dissipation efficiency and optimizing airflow, ensuring more efficient heat exchange between the evaporator and condenser while optimizing the airflow path.
[0061] Optionally, such as Figure 2 As shown, in one implementation of this embodiment,
[0062] The first partition plate group 201, the condenser 202, the rear wall 102 of the cabinet 1, and the top wall 103 of the cabinet 1 together enclose the condensation area; wherein, the condenser 202 is located in the air path between the first air inlet 1011 and the first air outlet 1012.
[0063] And / or, the evaporator 302 and the second partition plate group 301 together enclose a partial evaporation area; wherein, the evaporator 302 is located in the air path between the second air inlet 1013 and the second air outlet 1014.
[0064] In this embodiment, the condensation area is formed by the first partition plate group 201, the condenser 202, the rear wall 102 of the cabinet 1, and the top wall 103 of the cabinet 1. The condenser area is relatively independent and can provide better heat dissipation space for the refrigerant flowing through the condenser 202. This not only allows the airflow to flow evenly through the condenser 202, but also ensures that the heat released by the refrigerant does not affect other parts of the cabinet cavity 101, such as the cooling space of the evaporation area. The hot airflow generated in the condensation area is directly discharged from the first air outlet 1012 under the action of the fan.
[0065] The evaporator 302 is connected to the second partition plate group 301 to form a partial evaporation area. This evaporation area is relatively independent and can provide better cooling space for the refrigerant flowing through the evaporator 302. Not only can the airflow flow evenly through the evaporator 302, but the refrigerant also absorbs heat. The cold air located in the evaporation area is directly discharged from the second air outlet 1014 under the action of the fan, which can cool the room.
[0066] Optionally, as shown in Figures 2 and 4, in one implementation of this embodiment,
[0067] The first partition panel group 201 includes a first partition body 2011 located in the horizontal direction and a second partition body 2012 located in the vertical direction. One end of the second partition body 2012 is connected to the top wall 103 of the cabinet 1, and the other end is connected to the first partition body 2011. The condenser 202 is connected between the first partition body 2011 and the second partition body 2012, and the condenser 202 is attached to the side wall 104 of the cabinet 1.
[0068] The first air inlet 1011 is located on the side wall 104 of the cabinet 1, opposite to the condenser 202, and the first air outlet 1012 is located on the top wall 103 of the cabinet 1.
[0069] Preferably, at least two condensers 202 are provided, and a plurality of condensers 202 are arranged at intervals between opposite side walls of the cabinet 1;
[0070] At least one of the condensers 202 is attached to one side wall 104 of the cabinet 1, and at least one of the condensers 202 is attached to the other side wall 104 of the cabinet 1.
[0071] In this embodiment, two relatively small condensers 202 are used, which are symmetrically installed between the first partition 2011 and the second partition 2012. The first partition 2011 in the horizontal direction and the second partition 2012 in the vertical direction are integrally formed to form an L-shaped plate structure, which can not only support the condensers 202, but also be fixedly connected to the top wall 103 and side wall 104 of the cabinet 1 to ensure the connection of the first partition plate group 201. In this embodiment, the condensation area uses two compact condensers 202, which are close to the two symmetrical side walls 104 of the cabinet 1. The surface of the condenser 202 is parallel to the corresponding side wall 104, which not only saves space, but also improves heat dissipation efficiency. The first air inlet 1011 on the side wall 104 faces the surface of the condenser 202. Under the action of the fan, air enters the condenser 202 from the first air inlets 1011 on both sides, carries away heat, and is then directly discharged through the first air outlet 1012 on the top wall 103. The exhaust path is short, which improves the heat exchange efficiency of the condenser 202. This design ensures a uniform airflow distribution on the condenser 202, avoids local overheating, and improves the overall heat dissipation efficiency.
[0072] In this embodiment, the upper part of the cabinet cavity 101 is divided into an external fan cavity and an internal fan cavity by the first partition plate group 201 and the condenser 202. The external fan cavity, i.e., the condensation area, occupies most of the space, while the internal fan cavity, although small, is directly connected to the evaporation area located below, forming a complete internal fan cavity. The internal fan is installed on the upper inner panel, which can promptly exhaust the gas cooled by the evaporator 302. This design optimizes the airflow path and improves the heat exchange efficiency between the evaporator 302 and the condenser 202.
[0073] Optionally, such as Figure 4 As shown, in one implementation of this embodiment,
[0074] The first panel 2011 has a first folded edge 2013 on its periphery, and the first folded edge 2013 is connected to the side wall 104 and the rear wall 102 of the cabinet 1.
[0075] In this embodiment, the first partition panel 2011 is made of sheet metal, and the first folded edge 2013 is a sheet metal folded edge, which is fixedly connected to the side wall 104 and the rear wall 102, and the connection is fixed with screws. This ensures the firmness of the connection between the first partition panel 201 and the cabinet 1.
[0076] Optionally, such as Figure 4 , 5 As shown, in one implementation of this embodiment,
[0077] The periphery of the second partition plate group 301 is connected to the inner wall of the cabinet 1. The second partition plate group 301 includes a plurality of third partition plates 3011. The plurality of third partition plates 3011 are respectively connected to the periphery of the evaporator 302, and together with the evaporator 302, they form the heat exchange chamber having a lower air inlet end and an upper air outlet end.
[0078] The second air inlet 1013 is located on the front wall 105 of the cabinet 1 and is located below the air inlet end, while the second air outlet 1014 is located on the front wall 105 of the cabinet 1 and is located above the air outlet end.
[0079] Preferably, at least two evaporators 302 are provided, and a plurality of evaporators 302 are arranged at intervals along the vertical direction;
[0080] Multiple third plate bodies 3011 are connected between adjacent evaporators 302.
[0081] In this embodiment, the evaporator 302 is placed in the evaporation area at the bottom of the cabinet cavity 101. Connecting side plates are provided on both sides of the evaporator 302. These connecting side plates facilitate the connection of the evaporator with the drip tray 4, side wall 104, and rear wall 102, forming an internal fan cavity. This internal fan cavity is part of the evaporation area. The drip tray 4 is located below the evaporator 302, and below the drip tray 4 is the second air inlet 1013. Air enters a large and spacious air duct from the second air inlet 1013, flows evenly through the evaporator 302, and is then drawn away by the internal fan and discharged outside the machine. This design ensures the uniformity of airflow through the evaporator 302, improves evaporation efficiency, and simultaneously, the drip tray 4 effectively collects condensate, preventing water accumulation. Figure 5 The diagram shows the structure of the second partition plate group 301, which mainly consists of an evaporator 302 and the third partition plate body 3011 located on the front and rear sides, and the third partition plate body 3011 located on the left and right sides. Multiple third partition plate bodies 3011 are connected to two evaporators 302 arranged vertically with a gap, so that the inner fan cavity is relatively sealed, ensuring that air enters only from below the evaporator 302 located on the lower side and then exits from the evaporator 302 located on the upper side, thereby ensuring the uniformity of airflow through the evaporator and the high efficiency of heat exchange.
[0082] Optionally, such as Figure 2 , 4 As shown, in one implementation of this embodiment,
[0083] The condenser 202 is provided with a first connector 203 on its edge, and the first connector 203 is connected to the inner wall of the cabinet 1.
[0084] And / or, the edge of the evaporator 302 is provided with a second connector 303, which is connected to the inner wall of the cabinet 1.
[0085] Preferably, a water receiving tray 4 is provided between the second connector 303 and the inner wall of the cabinet 1, and the water receiving tray 4 is located on the lower side of the second partition plate group 301.
[0086] In this embodiment, the first connector 203 is an L-shaped folding plate, which is fixedly connected to the edge of the condenser 202 with screws. The L-shaped folding plate is also fixedly connected to the side wall 104 with screws, further ensuring the secure connection of the first partition plate assembly 201 in the upper part of the cabinet cavity 101. The second connector 303 is an L-shaped folding plate, which is fixedly connected to the edge of the evaporator 302 with screws. Multiple L-shaped folding plates are respectively fixedly connected to the side wall 104, the rear wall 102, and the water tray 4 fixedly connected to the front wall 105 with screws, further ensuring the secure connection of the second partition plate assembly 301 in the lower part of the cabinet cavity 101. The location of the water tray 4 not only prevents the airflow entering from the second air inlet 1013 from being directly discharged without being cooled by the evaporator 302, but also effectively collects the condensate produced by the evaporator 302, preventing water accumulation.
[0087] Optionally, such as Figure 3 , 4 As shown, in one implementation of this embodiment,
[0088] The bottom of the cabinet 1 is provided with a base 5, and a second folded edge 501 is formed on the periphery of the base 5. The second folded edge 501 is connected to the rear wall 102, side wall 104 and front wall 105 of the cabinet 1.
[0089] Wherein: the second folded edge 501 connected to the front wall 105 is connected to the side wall of the water receiving tray 4.
[0090] In this embodiment, the base 5 is fixedly connected to the rear wall 102, side wall 104, and front wall 105 respectively through multiple second folded edges 501 in the circumferential direction. A second air inlet 1013 is opened at the bottom of the front wall 105, and a water receiving tray 4 is provided above the second air inlet 1013. The water receiving tray 4 is connected to the second folded edge 501 on the front side of the base 5 by screws. This connection method can fix the water receiving tray 4 and the second folded edge 501 simultaneously with a set of screws and screw holes, which can reduce the number of openings on the front wall 105.
[0091] The evaporator 302 is located above the water tray and is fixedly connected to the water tray 4, the left side wall 104, the right side wall 104, and the rear wall 102 via multiple second connectors 303. The base design further enhances the overall stability of the cabinet.
[0092] Optionally, such as Figure 3 , 4 As shown, in one implementation of this embodiment,
[0093] A first fan 6 is installed at the first air outlet 1012, and a second fan 7 is installed at the second air outlet 1014;
[0094] Multiple first air outlets 1012 and multiple first fans 6 are provided. Multiple first air outlets 1012 correspond one-to-one with multiple first fans 6. Multiple first air outlets 1012 are spaced apart on the top wall of the cabinet 1.
[0095] In this embodiment, during operation, the condenser 202 and evaporator 302 work as follows: In the evaporation zone, the refrigerant vaporizes and absorbs heat through the evaporator 302, cooling the airflow in the evaporation zone. The second fan 7 can be understood as the internal fan in the above embodiment; its operation causes airflow to enter through the second air inlet 1013, be cooled by the evaporator 302, and be discharged from the room through the second air outlet 1014, thus cooling the room. In the condensation zone, the refrigerant liquefies and releases heat through the condenser 202. The first fan 6 can be understood as the external fan in the above embodiment; its operation causes airflow to enter the condenser 202 through the first air inlet 1011, carrying away heat from the condensation zone, and being discharged outdoors through the first air outlet 1012. Multiple small external fans are used and installed above the unit. A first air inlet 1011 is provided on the side wall 104, corresponding to the surface of the condenser 202, so that air can enter the condenser 202 from both sides of the unit, take away the heat generated therefrom, and then blow the hot air out by the external fan. The design of using multiple small fans instead of a single large fan provides a more uniform air velocity distribution, avoids local overheating, and improves the uniformity and efficiency of overall heat dissipation.
[0096] Optionally, in one implementation of this embodiment, such as Figure 2-5 As shown, Figure 3 The integrated cabinet air conditioner shown has an overall structure. Figure 4 This is an exploded view of the air conditioner's assembly structure.
[0097] The air conditioner's structure mainly consists of the following components: rear wall 102, second connector 303 located around the evaporator 302, second partition plate assembly 301, evaporator 302, side walls 104 located on the left and right sides, first partition plate assembly 201, condenser 202, base 5, drip tray 4, front wall 105, mesh cover, second fan 7, electrical box components, top wall 103, and first fan 6. Although not shown in detail in the diagram, the actual product also includes key details such as compressor, piping, fixing screws, rivets, and sealing strips. This does not mean that these parts are not needed in the production of the unit.
[0098] The integrated cabinet 1 consists of a front wall 105, side walls 104, rear wall 102, top wall 103, and base 5, with each component connected and fixed by fasteners. First air inlets 1011 are located on the upper part of the left and right side walls 104 near the rear wall 102, and condensers 202 are installed at positions corresponding to the first air inlets 1011 on the left and right side walls 104. Screw holes are pre-drilled in the side panels of the condenser 202, which are then fixed to the side walls 104 using fasteners.
[0099] Multiple external fan components are installed in the external fan cavity, directly above the condensation area. These multiple external fans, or multiple first fans 6, are fixed to the top wall 103 with screws. The top wall 103 has first air outlets 1012 at the positions corresponding to the external fans. In the actual product, the partitions inside the external fan cavity, i.e., the first partition plate group 201, also house key components such as compressors; these details are not shown in the attached drawings.
[0100] In addition, an internal fan, namely a second fan 7 and an electrical box assembly, is installed between the first partition panel 201 and the front wall 105. The second fan 7 and the electrical box assembly are both fixed to the front wall 105 with screws. The front wall 105 is installed on the cabinet 1 in an openable manner. The second fan 7 and the electrical box assembly can move synchronously with the movement of the front door panel, which is convenient for maintenance and repair.
[0101] Figure 1 The structural layout of a traditional integrated cabinet is shown. In this traditional design, due to space constraints, the lower part of the evaporator and the upper part of the condenser are almost flush with the partition 1', resulting in a significant reduction in airflow in this area. This design means that the evaporator in this area may not be able to fully absorb heat, leading to excessively high refrigerant temperatures when it leaves the evaporator. This not only reduces the refrigerant's heat absorption capacity but also affects the overall cooling efficiency of the system. Furthermore, overheated refrigerant entering the compressor can cause a decrease in compressor efficiency, increased energy consumption, and even a shortened compressor lifespan. More seriously, if the refrigerant cannot fully absorb heat and vaporize within the evaporator, it may result in incomplete vaporization, causing the compressor to draw in wet vapor, which can lead to liquid slugging and severely damage the compressor.
[0102] To address the aforementioned issues, this embodiment optimizes the airflow duct structure within the cabinet cavity 101 by installing a first partition plate group 201 at the upper part and a second partition plate group 301 at the lower part. The integrated cabinet is vertically divided into upper and lower sections. A condensation area is formed in the upper part of the cabinet cavity 101, and an evaporation area is formed in the lower part. The two areas are relatively independent. The upper area, i.e., the condensation area, mainly houses key components such as the condenser, external fan, and compressor, while the lower area, i.e., the evaporation area, is equipped with components such as the evaporator and water tray. The two areas are physically isolated by partitions. This partition design helps to clearly distinguish between the condensation and evaporation processes, avoid mutual interference, and optimize space utilization.
[0103] The upper part of the cabinet cavity 101 is divided into an external fan cavity and an internal fan cavity by a first partition plate group 201. The external fan cavity occupies most of the space, while the internal fan cavity, although smaller, is connected to the lower part of the cabinet, together forming a complete internal fan cavity. An internal fan is installed on the inner panel at the upper part of the internal fan cavity. The internal fan promptly extracts the gas passing through the evaporator and exhausts it outside the cabinet. The optimized air duct design makes the air velocity through the condenser and evaporator more uniform, ensuring that the heat removed by both is basically the same, avoiding local overheating or insufficient heat dissipation.
[0104] Maintaining a consistent evaporation state of the refrigerant in the evaporator not only facilitates system commissioning and operation but also ensures that the unit can achieve optimal performance.
[0105] The integrated cabinet design proposed in this embodiment optimizes the structure and layout of the two evaporators and the air duct design through the use of two partitions, significantly improving the cooling cycle efficiency of the air conditioning system. This design excels in improving heat dissipation efficiency and optimizing airflow, ensuring more efficient heat exchange between the evaporator and condenser while optimizing the airflow path.
[0106] The improved cooling efficiency of air conditioners not only reduces the load on the compressor but also lowers the overall energy consumption of the system, thereby reducing operating costs and avoiding energy waste. For example... Figure 1 As shown, in existing structures, improper duct design can lead to insufficient refrigerant evaporation in the evaporator flow path, causing liquid slugging and severely damaging the compressor. The integrated cabinet proposed in this embodiment ensures sufficient refrigerant evaporation in the evaporator, preventing liquid refrigerant from entering the compressor, thereby extending the compressor's lifespan and improving system reliability.
[0107] It should be noted that the refrigeration system and other components inside the cabinet air conditioner in this embodiment are not shown in the accompanying drawings, because the assembly and fixing of these components are not related to the main improvement points of this embodiment. The main improvement points of this embodiment are the layout of the two heat exchangers and the fan and the related structural design.
[0108] The air conditioner's cooling process is as follows:
[0109] The refrigerant evaporates and absorbs heat in the evaporator 302, becoming a low-pressure gas (hot air enters and cold air exits in cabinet 101, absorbing heat); the low-pressure gas enters the compressor and is compressed into a high-temperature, high-pressure gas; the high-temperature, high-pressure gas flows through the condenser 202 and liquefies, releasing heat to become a medium-high-temperature, high-pressure liquid (cold air enters and hot air exits in cabinet 101, releasing heat); the medium-high-temperature, high-pressure liquid passes through a throttling valve (not shown in the attached diagram) and becomes a low-temperature, low-pressure liquid; these liquids flow into the evaporator 302 and absorb heat to evaporate, becoming a low-temperature, low-pressure gas, thus completing the closed loop.
[0110] All-in-one cabinets are typically used for high-density equipment (such as servers, switches, base stations, storage devices, etc.), which generate a lot of heat when they are running. Therefore, their core function is heat dissipation, not heat generation.
[0111] If the aforementioned equipment (such as servers, switches, base stations, storage devices, etc.) is located in extremely cold regions, heating can be achieved by directing the hot air discharged from the first air outlet 1012 of the air conditioner to the room that needs heating, and the second air outlet 1014 to the outside, or by adding an electric heater inside the cabinet cavity 101.
[0112] In summary, the ingenious design of the integrated rack air conditioner lies in:
[0113] First, by setting a first partition group at the top and a second partition group at the bottom of the cabinet cavity, the air duct structure for airflow within the cabinet cavity is optimized. The integrated cabinet is vertically divided into upper and lower parts, forming a condensation area in the upper part of the cabinet cavity and an evaporation area in the remaining part of the cabinet cavity. The two areas are relatively independent and are physically isolated from each other by a partition. This partition design helps to clearly distinguish between the condensation and evaporation processes, avoid mutual interference, and optimize space utilization.
[0114] Secondly, the condensation area employs two compact condensers, closely attached to the two symmetrical side walls of the cabinet. The condenser surfaces are parallel to the corresponding side walls, saving space and improving heat dissipation efficiency. The first air inlet on the side panel faces the condenser surface. Under the action of the fan, air enters the condenser from the first air inlet on both sides, carrying away heat before being discharged through the first air outlet. This design ensures uniform airflow distribution on the condenser, avoiding localized overheating and improving overall heat dissipation efficiency. The upper part of the cabinet cavity is divided into an external fan cavity and an internal fan cavity by the first partition plate assembly and the condenser. The external fan cavity, i.e., the condensation area, occupies most of the space, while the internal fan cavity, although small, is directly connected to the evaporation area located below, forming a complete internal fan cavity. The internal fan is installed on the upper inner panel, allowing for timely exhaust of the gas cooled by the evaporator. This design optimizes the airflow path and improves the heat exchange efficiency between the evaporator and condenser.
[0115] Third, the second partition plate group mainly consists of the third partition plate body located on the front and rear sides and the third partition plate body located on the left and right sides. Multiple third partition plates are connected to two evaporators arranged vertically with a gap, so that the inner fan cavity is relatively sealed, ensuring that air enters only from below the evaporator located on the lower side and then exits from the evaporator located on the upper side, thereby ensuring the uniformity of airflow through the evaporator and the high efficiency of heat exchange.
[0116] Fourth, multiple small external fans are used and installed above the unit. A first air inlet is opened on the side wall corresponding to the condenser surface, allowing air to enter the condenser from both sides of the unit, carrying away the heat generated, and then the hot air is blown out by the external fans. The design using multiple small fans instead of a single large fan provides a more uniform airflow distribution, avoids localized overheating, and improves the overall uniformity and efficiency of heat dissipation.
