[0004] In current dehumidification equipment, the evaporator and condenser are mostly installed side-by-side along the thickness of the equipment, resulting in a thicker dehumidification unit with a less compact internal structure and a larger size, which limits its use. When installing dehumidification equipment inside server racks housing servers or energy storage units, it occupies a significant amount of internal space, relatively reducing the space available for the servers or energy storage units. Furthermore, dehumidification equipment cannot be used in some small server rack scenarios. Summary of the Invention

[0014] Furthermore, an electronic control component is also provided in the first cavity of the indoor cavity, the electronic control component including a heating element and a solenoid valve arranged sequentially with the evaporator fan along the third direction;

[0015] An operation panel is provided inside the second cavity.

[0016] Furthermore, a partition is provided in the first cavity between the evaporator and the evaporation fan, and the width of the partition is less than the thickness of the shell to ensure the indoor air duct;

[0017] The electronic control components and the evaporator are separated by the partition.

[0020] The outlet of the first solenoid valve is connected to the inlet of the condenser;

[0021] The outlet of the condenser is connected in sequence to the throttling unit and the inlet of the evaporator, and the outlet of the evaporator is connected to the inlet of the compressor.

[0035] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. 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 in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. In the following description, the expression "some embodiments" refers to a subset of all possible embodiments; however, it should be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with each other without conflict.

[0036] It should also be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "inner," "outer," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0037] This invention provides an integrated dehumidification device that can select and switch between multiple operating modes, including heating, cooling, and dehumidification, according to environmental needs. It should be noted that the term "dehumidification device" can refer only to a standalone product primarily featuring dehumidification, such as a dehumidifier; or it can refer to other products incorporating the air conditioning functions of the dehumidification device provided in this application, such as air conditioners and temperature control devices. Please refer to the appendix for further details. Figure 1 and attached Figure 2The integrated dehumidifier includes a housing 1, a partition component 2 disposed within the housing 1, and a dehumidification system. The partition component 2 divides the space within the housing 1 into an indoor cavity 11 and an outdoor cavity 12. The dehumidification system includes an evaporator 31 installed in the indoor cavity 11 and a condenser 34 installed in the outdoor cavity 12. Further, the X-axis direction is defined as the first direction, the Z-axis direction as the second direction, and the Y-axis direction as the third direction, wherein the projections of the evaporator 31 and the condenser 34 on the plane perpendicular to the first direction at least partially overlap. The outdoor cavity 12 includes a first sub-cavity 121 and a second sub-cavity 122. The first sub-cavity 121 and the indoor cavity 11 are arranged side by side along the second direction of the shell 1, and the second sub-cavity 122 and the indoor cavity 11 are arranged side by side along the first direction of the shell 1. The dehumidification system also includes an evaporator fan 32 installed in the indoor cavity 11 and a compressor 33 and a condenser fan 35 installed in the outdoor cavity 12. The compressor 33 and the condenser fan 35 are installed side by side in the first sub-cavity 121 along the first direction of the shell 1, and the condenser 34 is installed in the second sub-cavity 122.

[0038] For example, the thickness of the condenser 34 and the thickness of the evaporator 31 can be the same. The evaporator 31 and the condenser 34 are respectively installed in the second sub-chamber 122 of the inner cavity 11 and the outer cavity 12. The second sub-chamber 122 is parallel to the portion of the inner cavity 11 that houses the evaporator 31 in the first direction of the housing 1, and overlaps with the portion of the inner cavity 11 that does not house the evaporator 31 in the third direction of the housing 1. From the third direction of the thickness of the housing 1, the thicknesses of the evaporator 31 and the condenser 34 can completely overlap. Thus, the thickness of the housing 1 can depend only on the thickness of the larger of the two, the evaporator 31 and the condenser 34, and will be at least less than the sum of the thicknesses of the two.

[0039] In the actual design of the integrated dehumidification device provided in this embodiment, the thickness of the housing 1 can be designed according to the minimum size of the compressor 33, and other components can be selected adaptively according to the requirements, so as to maximize the size of the housing 1.

[0040] The integrated dehumidification device provided in this embodiment can be applied to energy storage, data centers, etc. Currently, with the rapid development of data center and energy storage technologies, the demand for dehumidification in data centers and energy storage is constantly increasing. For outdoor cabinets used in general data centers and energy storage, ordinary air conditioners are often used for dehumidification or cooling. This method has problems such as large fluctuations in humidity control and can no longer meet the humidity control requirements of existing energy storage equipment. Therefore, the known method of setting up dehumidification equipment inside the shell containing servers or energy storage units to cool or dehumidify the shell and ensure that the servers or energy storage units can operate efficiently and reliably, is problematic. However, dehumidification equipment often occupies a large amount of internal space in the shell, relatively reducing the space available for servers or energy storage units. Furthermore, it cannot be used in some shell scenarios with limited space, which greatly limits its application and makes it less applicable.

[0041] Therefore, in this embodiment, the space within the housing 1 is divided into an inner cavity 11 and an outer cavity 12 by the partition component 2. The outer cavity 12 includes a first sub-cavity 121 and a second sub-cavity 122. The first sub-cavity 121 and the inner cavity 11 are arranged side by side along the second direction of the housing 1, and the second sub-cavity 122 and the inner cavity 11 are arranged side by side along the first direction of the housing 1. The evaporator 31 and the evaporator fan 32 of the dehumidification system are installed in the inner cavity 11, and the compressor 33 and the condenser fan 35 are installed in the first sub-cavity 121. Evaporator 31 and condenser 34 are installed in the second sub-chamber 122. The evaporator 31 and condenser 34 at least partially overlap along a third direction of the casing 1. This arrangement rationally divides the internal space of the casing 1 using the partition component 2, making efficient use of each space. The ingenious design of the evaporator 31 and condenser 34 at least partially overlapping along a third direction of the casing 1 makes the internal space of the casing 1 more compact, resulting in a flatter, more streamlined dehumidification structure. This reduces the space occupied by the entire dehumidification device and enhances its versatility. Furthermore, the arrangement of the evaporator 31 and condenser 34 at least partially overlapping along a third direction of the casing 1, compared to the prior art where the evaporator 31 and condenser 34 are installed side-by-side along a third direction of the casing, ensures a superior airflow and a larger heat exchange area, thus improving the overall efficiency of the dehumidification device.

[0042] Please refer to the appendix again. Figure 1The first direction is the width direction of the integrated dehumidifier, the second direction is the height direction of the integrated dehumidifier, and the third direction is the thickness direction of the integrated dehumidifier. The outdoor cavity 12 includes a first sub-cavity 121 arranged parallel to the indoor cavity 11 along the Z-axis and a second sub-cavity 122 arranged parallel to the indoor cavity 11 along the X-axis. The space inside the shell 1 is divided by the partition component 2 to form an upper half space and a lower half space with the bottom end of the indoor cavity 11 as the boundary. The indoor cavity 11 is entirely located in the upper half space of the shell 1. The outdoor cavity 12 includes the first sub-cavity 121 located in the lower half space and the second sub-cavity 122 formed by the remaining space in the upper half space after removing the indoor cavity 11. That is, by setting the partition component 2, the indoor cavity 11 and the outdoor cavity 12 are isolated from each other, and the space inside the housing 1 is divided as follows: the indoor cavity 11 is located in the upper half of the housing 1, and the outdoor cavity 12 is mainly located in the lower half of the housing 1. A part of the space in the upper half of the housing 1 is divided into the outdoor cavity 12 to provide for the installation of the condenser.

[0043] In one optional embodiment, the inner cavity 11 includes a first cavity 111 and a second cavity 112. The first cavity 111 and the second sub-cavity 122 are arranged side by side along a first direction of the housing 1, and the second cavity 112 and the second sub-cavity 122 are arranged side by side along a third direction of the housing 1. The evaporator 31 and the evaporator fan 32 are arranged side by side in the first cavity 111 along a second direction of the housing. Specifically, the inner cavity 11 includes a first cavity 111 arranged side by side with the second sub-cavity 122 along the X-axis and a second cavity 112 arranged side by side with the second sub-cavity 122 along the Y-axis. The evaporator 31 and the evaporator fan 32 are arranged side by side in the first cavity 111 along the Z-axis. The partition component 2 divides the upper half of the housing 1 into a left half and a right half along the X-axis. Further, it divides the right half into a front half and a rear half along the Y-axis. The left half can be understood as the first cavity 111, the front half as the second cavity 112, and the rear half as the second sub-chamber 122. In other words, by setting up the partition component 2, a portion of the upper half of the housing 1 is divided along the Y-axis, forming the second cavity 112 of the inner cavity 11 and the second sub-chamber 122 of the outer cavity 12, which are stacked along a third direction of the housing 1. The second cavity 112 can accommodate components with smaller thicknesses within the inner cavity 11, such as electronic control components, to maximize the overall space size of the inner cavity 11. This ensures the overall storage capacity of the inner cavity 11 while effectively reducing the increase in the thickness of the housing 1.

[0044] In an optional embodiment, the dehumidification system further includes a reheater 36 disposed within the indoor cavity 11 for reheating humid air after dehumidification and cooling. The reheater 36 and the evaporator 31 are stacked together along a third direction of the casing. Compared to the prior art, this embodiment achieves dehumidification while reducing power consumption. This is because most dehumidification devices typically use electric heating to raise the temperature for the function of reheating humid air after dehumidification and cooling, but starting electric heating results in energy waste. In this embodiment, the reheater 36 is connected to the compressor 33, and the high-temperature, high-pressure gas discharged from the compressor 33 can be used to heat the dehumidified cold air from the evaporator 31. The evaporator 31 has end plates 311 extending along a third direction of the casing 1 on opposite sides, and an indoor air duct is defined between the end plates 311. The arrangement of the end plates 311 allows the air to be more concentrated in the indoor air duct. The evaporator 31 and the reheater 36 can be an integrated structure, allowing them to share a common air duct. That is, the indoor air duct formed by the end plate 311 can reduce the dimensions along the third direction of the shell 1, and make installation more convenient. In addition, when the cold air dehumidified by the evaporator 31 enters the reheater 36, it can be further dehumidified, reducing the humidity of the air at the air duct outlet, ensuring the temperature of the dehumidified air while improving the dehumidification efficiency.

[0045] In an optional embodiment, an electronic control component is further provided in the first cavity 111 of the inner cavity 11. The electronic control component includes a solenoid valve 371 and a heating element 372 arranged sequentially with the evaporator fan 32 along a third direction of the housing 1. An operation panel 38 is further provided in the second cavity 112 of the inner cavity 11.

[0046] In one optional embodiment, a partition is provided in the first cavity 111 between the evaporator 31 and the evaporation fan 32. The width of the partition is less than the thickness of the shell to ensure the indoor air duct. The electrical control component and the evaporator 31 are separated by the partition to prevent condensate generated on the surface of the evaporator 31 from splashing onto the electrical control component and affecting its normal operation.

[0047] In one optional embodiment, the solenoid valve 371 includes a first solenoid valve 3711 and a second solenoid valve 3712. The inlets of the first solenoid valve 3711 and the second solenoid valve 3712 are connected to the outlet of the compressor 33. The outlet of the second solenoid valve 3712 is connected to the inlet of the reheater 36, and the outlet of the reheater 36 is connected to the inlet of the condenser 34. The outlet of the first solenoid valve 3711 is connected to the inlet of the condenser 34. The outlet of the condenser 34 is sequentially connected to the inlet of the throttling unit and the evaporator 31, and the outlet of the evaporator 31 is connected to the inlet of the compressor 33. For details, please refer to the appendix. Figure 3The inlets of the first solenoid valve 3711 and the second solenoid valve 3712 are connected in parallel to the outlet of the compressor 33 via copper pipes. The outlet of the second solenoid valve 3712 is connected to the inlet of the reheater 36 via a copper pipe, and the outlet of the reheater 36 is connected to the inlet of the condenser 34 via a copper pipe. The outlet of the first solenoid valve 3711 is connected to the inlet of the condenser 34 via a copper pipe. The outlet of the condenser 34 is connected to the inlet of the throttling unit 39 and the evaporator 31 via copper pipes in sequence. The outlet of the evaporator 31 is connected to the inlet of the compressor 33 via a copper pipe. In this embodiment, the specific installation position of the copper pipes is not limited, and the installation position of the copper pipes can be reasonably designed according to the requirements and the distribution position of various components in the housing 1. In cooling mode, the dehumidifier opens the first solenoid valve 3711 and closes the second solenoid valve 3712. High-temperature, high-pressure gas from the compressor 33 passes through the first solenoid valve 3711 to the condenser 34, where it is condensed into a high-pressure liquid. This high-pressure liquid then passes through a throttling element to become a low-pressure liquid. The low-pressure liquid then evaporates in the evaporator 31, becoming a low-pressure gas that flows back to the compressor 33. This cycle repeats to achieve a cooling effect. In dehumidification mode, when temperature compensation for dehumidification is required, the second solenoid valve 3712 opens and the first solenoid valve 3711 closes. High-temperature, high-pressure gas from the compressor 33 passes through the second solenoid valve 3712 to the reheater 36 for heat release. It then further condenses in the condenser 34, becoming a high-pressure liquid. This high-pressure liquid passes through a throttling element to become a low-pressure liquid. The low-pressure liquid then evaporates in the evaporator 31, becoming a low-pressure gas that flows back to the compressor 33. This cycle repeats to achieve a dehumidification effect. When the dehumidifier is in heating mode, only the heating element 372 and the evaporator fan 32 operate, eliminating the need for the evaporator 31, condenser 34, and compressor 33, thus saving energy. The dehumidifier integrates cooling, heating, dehumidification, and reheating functions, switching between these modes via the opening and closing of the first solenoid valve 3711 and the second solenoid valve 3712.

[0048] The integrated dehumidifier provided in this embodiment can also be used in household temperature control devices with dehumidification function, such as household dehumidifiers with waste heat recovery. The evaporator and condenser share a common circulating air path. After the humid air is dehumidified by the evaporator, it is directly heated and processed by the condenser. Although it has certain effects in humidity control and energy saving, it loses the temperature control function of the air conditioner, and its application is greatly limited. In a household dehumidifier, the evaporator 31 and condenser 34 configuration provided in this embodiment can be used. The reheater 36 and the evaporator 31 share a common air duct. The inlet of the reheater 36 is connected to the second solenoid valve 3712 of the control component. When it is determined that dehumidification temperature compensation is required, the second solenoid valve 3712 will open to connect the compressor 33 with the reheater 36 to heat the dehumidified cold air. In the prior art, the evaporator 31 and condenser 34 share a common air duct. In dehumidification or cooling mode, the condenser 34 is always connected to the compressor 33. Therefore, when the high-temperature and high-pressure gas in the compressor 33 passes through the condenser 34, it will affect the air temperature around the evaporator 31.

[0049] In one optional embodiment, the indoor cavity 11 is provided with an indoor air inlet and an indoor air outlet in sequence along the second direction of the housing 1, forming an indoor air duct between the indoor air inlet and the indoor air outlet; the outdoor cavity 12 is provided with an outdoor air inlet and an outdoor air outlet in sequence along the second direction of the housing 1, forming an outdoor air duct between the outdoor air inlet and the outdoor air outlet; the airflow direction of the indoor air duct is opposite to the airflow direction of the outdoor air duct. For example, the indoor air inlet is positioned opposite to the evaporator fan 32, and the indoor air outlet is positioned opposite to the evaporator 31; the outdoor air inlet is positioned opposite to the condenser fan 35, and the outdoor air outlet is positioned opposite to the condenser 34. When the condenser fan 35 is running, airflow flows into the outdoor cavity 12 through the outdoor air inlet, cools and dissipates the heat generated around the condenser 34, and then is blown out through the outdoor air outlet, achieving the effect of heat dissipation.

[0050] The reheater 36 and the evaporator 31 share the same indoor air outlet and are located before or after the evaporator 31. This can reduce the dimensions along the third direction of the casing 1. At the same time, when the cold air dehumidified by the evaporator 31 enters the reheater 36, it can be further dehumidified, reducing the humidity of the air at the air outlet and improving the dehumidification efficiency while ensuring the temperature of the dehumidified air.

[0051] In an optional embodiment, the partition assembly 2 includes a first partition plate 21 that divides the space inside the housing 1 along a first direction of the housing 1, a second partition plate 22 that divides the space inside the housing 1 along a third direction of the housing 1, and a water collection box 40 that divides the space inside the housing 1 along a second direction of the housing 1. The second partition plate 22 is inclined along the third direction of the housing 1, such that the second sub-chamber 122 is tapered in size along the third direction of the housing 1 towards the outdoor air outlet. Thus, the second sub-chamber 122 of the outdoor cavity 12 forms a space for a condensing air duct that is smaller at the top and larger at the bottom. The condenser 34 is installed in the space of the condensing air duct. The second cavity 112 of the indoor cavity 11 forms a space that is larger at the top and smaller at the bottom for installing the operation panel 38. Please refer again. Figure 1 The second cavity 112 has an inverted trapezoidal cross-sectional shape along the third direction of the shell 1, and the second sub-chamber 122 has a regular trapezoidal cross-sectional shape along the third direction of the shell 1. The two are separated by a second partition plate 22, which forms a matrix-like cross-section along the third direction of the shell 1. The second partition plate 22 separates the space of the condenser duct and the installation space of the operation panel 38, making reasonable use of space while minimizing the space size. Furthermore, the second sub-chamber 122 is approximately inverted V-shaped, and the second cavity 112 is approximately V-shaped. The second sub-chamber 122 and the second cavity 112 are combined to form a cuboid structure. In order to further minimize the space size, the condenser 34 can be set close to the rear inner wall of the shell 1. The side of the condenser 34 away from the rear inner wall of the shell 1 forms a condensing air duct that gradually narrows from bottom to top between it and the second partition plate 22. The operation panel 38 is set close to the front wall of the shell 1. The side of the second partition plate 22 away from the evaporator fan 32 extends towards the operation panel 38 to form a baffle plate to prevent hot air in the condensing air duct from entering the indoor air duct and affecting the cooling effect.

[0052] In one optional embodiment, a water collection box 40 is laterally arranged inside the housing 1 along a first direction. The orthographic projection of the evaporator 31 along a second direction of the housing 1 falls completely into the water collection box 40. The first sub-chamber 121 of the outdoor cavity 12 is located below the water collection box 40, and the indoor cavity 11 is located above the water collection box 40. Specifically, the water collection box 40 is installed laterally in the first direction of the housing 1, and both ends of the water collection box 40 abut against the left and right sides of the housing 1 in the first direction. That is, the water collection box 40 can be understood as including a first section located below the evaporator 31 and a second section located below the operation panel 38. The width of the first section is at least greater than the thickness of the evaporator 31, so that the condensate produced by the evaporator 31 can fall into the water collection box 40 more effectively. For example, the width of the first section is the same as the thickness of the evaporator 31 after it is combined with the reheater 36. The width of the second section is less than the width of the first section. By setting the second section, on the one hand, the capacity of the water collection box 40 is increased, and on the other hand, it serves to separate the indoor cavity 11 and the outdoor cavity 12.

[0053] The integrated dehumidification device provided in the above embodiments has at least the following technical effects:

[0054] (1) By rationally dividing the internal space of the housing 1 through the partition component 2, and making reasonable use of the resulting inner cavity 11, first sub-cavity 121 and second sub-cavity 122, and through the ingenious design that the projections of the evaporator 31 and the condenser 34 on the vertical plane perpendicular to the first direction at least partially overlap, the internal space of the housing 1 becomes more compact, the thickness of the housing 1 becomes thinner, and the space occupied by the entire dehumidification device is smaller and more universal; secondly, by setting the projections of the evaporator 31 and the condenser 34 on the vertical plane perpendicular to the first direction at least partially overlap, compared with the prior art technique of installing the evaporator 31 and the condenser 34 side by side along the thickness direction of the housing, it can ensure a better air duct and a larger heat exchange area, thereby improving the overall working efficiency of the dehumidification device.

[0055] (2) By installing a reheater 36 in the inner cavity 11 and connecting the reheater 36 and the condenser 34 in parallel to the outlet of the compressor 33 through the first solenoid valve 3711 and the second solenoid valve 3712, when it is determined that dehumidification temperature compensation is required, the second solenoid valve 3712 is opened to connect the compressor 33 and the reheater 36, and the cold air after dehumidification of the evaporator 31 is reheated. On the one hand, power consumption can be reduced, on the other hand, temperature compensation can be performed according to temperature requirements, so that the temperature of the dehumidified air is suitable, and on the other hand, the condensation heat exchange area can be increased.

[0056] (3) The dehumidification equipment integrates multiple functions such as refrigeration, heating, dehumidification and reheating. The switching between refrigeration and dehumidification and reheating is achieved by opening and closing the first solenoid valve 3711 and the second solenoid valve 3712.

[0057] (4) By sharing an indoor air duct with the reheater 36 and the evaporator 31, the dimensions along the third direction of the shell 1 can be reduced. At the same time, when the cold air dehumidified by the evaporator 31 enters the reheater 36, it can be further dehumidified, reducing the humidity of the air at the air duct outlet, ensuring the temperature of the dehumidified air while improving the dehumidification efficiency.

[0058] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. The scope of protection of the present invention should be determined by the scope of the claims.
