[0051] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0052] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0053] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0054] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0055] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0056] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0057] In the current field of environmental control, existing environmental control systems typically use independent air temperature control systems, which only have the function of controlling ambient temperature. They are single-function and do not have efficient filtration capabilities. For working environments with high requirements for air cleanliness, such as cleanrooms, existing environmental control systems cannot meet the requirements for controlling environmental cleanliness and cannot simultaneously achieve temperature control and air filtration functions.

[0058] To address the problems in the prior art, this application provides an environmental control device that simultaneously achieves temperature control and air filtration functions.

[0059] Figure 1 This is a schematic diagram of the structure of the environmental control device provided in the embodiments of this application from one perspective, such as... Figure 1 As shown, the environmental control equipment is a cabinet-type environmental control equipment. Figure 2 This is a partial structural diagram of an environmental control device provided in one embodiment of this application, as shown below. Figure 2As shown, the environmental control equipment includes a cabinet 1, a first cavity 2, a fan cavity 3, and a second cavity 4. The cabinet 1 has a certain height and internal space. The first cavity 2, fan cavity 3, and second cavity 4 can be arranged inside the cabinet 1 and connected sequentially in any order, so that the airflow can pass through each cavity in the corresponding order. For ease of description, a specific sequential arrangement can be preset: in one example, the first cavity 2, fan cavity 3, and second cavity 4 are connected sequentially in the aforementioned order, so that the airflow passes through the first cavity 2, fan cavity 3, and second cavity 4 sequentially; or the second cavity 4, first cavity 2, and fan cavity 3 are connected sequentially in the aforementioned order, so that the airflow passes through the second cavity 4, first cavity 2, and fan cavity 3 sequentially; or other sequential connection methods. The above sequential connection can be arranged sequentially in a certain direction in space, or in other forms, such as a bend.

[0060] The first cavity 2 is equipped with a heat exchange module 5, which serves as a heat exchange chamber. The heat exchange module 5 is generally a heat exchanger, and its internal channels can be used to flow refrigerant, water, or other heat exchange fluids. The heat exchange fluid exchanges heat with the air or other fluids flowing through the first cavity 2 through the heat exchange module 5. Based on this, the first cavity 2 can also be referred to as a heat exchange chamber.

[0061] A fan 7 is installed in the fan cavity 3 to drive the airflow so that the airflow is directed in a predetermined direction. A filter device is installed in the second cavity 4 to filter impurities from the airflow.

[0062] At least one of the first cavity 2, the fan cavity 3, and the second cavity 4 is equipped with a heating device 8 for heating the air. The heating device 8 is generally located downstream of the heat exchange module 5, that is, the air first passes through the heat exchange module 5, and then through other modules before flowing to the heating device 8, or it flows directly to the heating device 8 without passing through other modules.

[0063] In one example, the heat exchange module 5 is used to initially adjust the temperature of the air, while the heating device 8 is used to further and more precisely adjust the temperature of the air, thus better realizing the process from coarse adjustment to fine adjustment.

[0064] In some embodiments, a heat exchange module 5 is provided in the first cavity 2, and an air inlet 21 is provided on the first cavity 2. The heat exchange module 5 is used to receive the air entering through the air inlet 21. The air can exchange heat in the heat exchange module 5. The heat exchange module 5 can achieve preliminary adjustment of the air temperature to ensure more accurate temperature adjustment by the heating device 8 later.

[0065] Figure 3 for Figure 2 The cross-section at point AA, as shown Figure 3 As shown, the fan cavity 3 is located inside the cabinet 1 and above the first cavity 2. The fan cavity 3 is equipped with a fan 7, which can guide the airflow so that the air passing through the heat exchange module 5 can flow in the direction of the air outlet 111.

[0066] A heating device 8 is provided in the first cavity 2 and / or the fan cavity 3, which can heat the air passing through the heat exchange module 5.

[0067] The second cavity 4 is located inside the cabinet 1 and above the fan cavity 3. A filter device is installed in the second cavity 4, and the air filtered by the filter device is discharged to the environment outside the environmental control equipment through the air outlet 111.

[0068] In some embodiments, by integrating a heating device 8 and a filtering device in a cabinet 1, the environmental control equipment can simultaneously have temperature control and air filtration functions, enabling the environmental control equipment to achieve both ambient temperature control and high air cleanliness in working environments with high requirements for air cleanliness, such as cleanrooms.

[0069] In this embodiment, the filter device is installed inside the cabinet 1 near the air outlet 111. It can filter out pollutants from the external environment carried in the air before entering the air inlet 21, and also filter out pollutants from within the cabinet 1 that accumulate during airflow, thus effectively ensuring the cleanliness of the air discharged from the air outlet 111. This filter device, also known as a filter, can be selected according to the type of impurities being filtered. The specific structure and filtration method are not limited. The filter device can be one that filters dust and impurities, or one that filters chemical substances; it can also be a device that filters both dust and chemical substances, achieving a good filtration effect.

[0070] In some embodiments, the second cavity 4, the fan cavity 3, and the first cavity 2 are independent cavity structures, which can be assembled onto the frame 16 independently or individually. This allows for modularization of the structures and devices within the environmental control equipment; that is, the filter device can be integrated into the second cavity 4, the fan 7 into the fan cavity 3, and the heat exchange module 5 into the first cavity 2. When assembling onto the frame 16, only the second cavity 4, the fan cavity 3, and the first cavity 2 need to be assembled separately, eliminating the need to assemble individual, disparate structures or devices onto the frame 16. This simplifies the assembly operation of the environmental control equipment, greatly reduces assembly difficulty, and also facilitates the maintenance of each module. It should be noted that the specific assembly method is not limited.

[0071] In some instances, as shown in the attached diagram, Figure 4 for Figure 2 The enlarged view at point B, as shown Figure 4 As shown, a first corner piece 24 can be provided on the first cavity 2. The first cavity 2 can be fixedly connected to the frame 16 through the first corner piece 24. The first corner piece 24 can be fixedly connected to the first cavity 2 and the frame 16 respectively through screws, which facilitates the assembly of the first cavity 2 and the frame 16.

[0072] Figure 5 for Figure 3 The enlarged view at point C, as shown Figure 5 As shown, the bottom end of the fan cavity 3 can be fixed to the first cavity 2 by screws. Figure 6 for Figure 3 The enlarged view at point D, as shown Figure 6 As shown, the top of the fan cavity 3 can also be fixed to the second cavity 4 by screws. Therefore, the method of connecting the fan cavity 3 to the second cavity 4 and the first cavity 2 by screws facilitates the assembly of the second cavity 4, the fan cavity 3 and the first cavity 2, and ensures the reliability of the connection and fixation of the fan cavity 3 to the second cavity 4 and the first cavity 2.

[0073] Figure 7 for Figure 2 The magnified view at point E, as shown Figure 7 As shown, a second corner piece 41 can be provided on the second cavity 4. The second cavity 4 can be fixedly connected to the frame 16 through the second corner piece 41. The second corner piece 41 can be fixedly connected to the second cavity 4 and the frame 16 respectively through screws, which facilitates the assembly of the second cavity 4 and the frame 16.

[0074] In one embodiment, such as Figure 3As shown, the heating device 8 may include a first heating component 81 and a second heating component 82. The first heating component 81 may be disposed in the first cavity 2 and / or the fan cavity 3, and the second heating component 82 may be disposed in the fan cavity 3 and / or the second cavity 4. Along the air flow direction within the fan 7, the first heating component 81 and the second heating component 82 are located on opposite sides of the fan 7. Air entering from the air inlet 21 undergoes heat exchange through the heat exchange module 5, and then the heat-exchanged air is heated by the first heating component 81. The air heated by the first heating component 81 can be drawn into the fan cavity 3 by the fan 7 and reheated by the second heating component 82. This method generally results in more uniform air heating and better temperature control accuracy. By heating the air twice, the accuracy of air temperature control can be improved. The air heated by the second heating component 82 can flow to the second cavity 4 through the fan 7 for filtration by the filter device in the second cavity 4. The filtered air can then be discharged from the air outlet 111. The first heating element 81 and the second heating element 82 can better achieve temperature adjustment from coarse to fine.

[0075] Figure 8 This is a schematic diagram of the structure of the environmental control device provided in the embodiments of this application from another perspective, as shown below. Figure 1 and Figure 8 As shown, the cabinet 1 includes a frame 16, a front door panel 12, a rear door panel 13, a right door panel 14, a left door panel (not shown in the figure), and a top cover 11. The frame 16 can be a frame structure, and can include multiple crossbeams and multiple longitudinal beams, which can be connected to form a vertical frame structure. For ease of explanation, the frame 16 can be defined to have a first direction X, a second direction Y, and a third direction, which are mutually perpendicular. The third direction is the height direction Z of the environmental control equipment during use. The first direction X can be the front-to-back direction of the environmental control equipment during use, and the second direction Y is the left-to-right direction.

[0076] The top cover 11 is detachably connected to the top of the frame 16, and an air outlet 111 is provided on the top cover 11. To facilitate the installation and removal of the top cover 11, it can be fastened to the top of the frame 16 using screws. It should be noted that the screw connection described in this context is not limited to detachable methods such as bolts or snap-fit ​​connections.

[0077] The front door panel 12 and the rear door panel 13 are detachably connected to opposite sides of the frame 16 along a first direction X, allowing them to be detached from the frame 16 in directions away from it. In practical applications of the environmental control equipment, the front door panel 12 is located at the front of the equipment and may be equipped with operating knobs, control panels, etc., for user convenience. The rear door panel 13 is located at the rear of the equipment and is typically not visible to the user during normal use.

[0078] The cabinet can have one or two front door panels 12 and rear door panels 13. Both panels can be opened and closed by rotation or sliding. When it is necessary to perform debugging, maintenance, or replacement operations on the structure near the front door panel 12 or rear door panel 13 within the cabinet 1, the front door panel 12 or rear door panel 13 can be opened to facilitate the operation. After the operation is completed, the front door panel 12 or rear door panel 13 can be closed to protect the internal components.

[0079] The left and right door panels 14 are detachably connected to opposite sides of the rack 16 along the second direction Y, allowing them to be removed from the rack 16 in directions away from it. To facilitate the installation and removal of the left or right door panels 14, both panels are secured to the side of the rack 16 with screws. When adjustments, maintenance, or replacements are required on structures within the rack 1 near the left or right door panels 14, the corresponding panel can be removed for these operations, facilitating the operator's work. After the operation is completed, the left or right door panels 14 can be reinstalled on the rack 16 to protect internal components.

[0080] Therefore, by providing a detachable top cover 11, front door panel 12, rear door panel 13, left door panel, and right door panel 14, this embodiment enables the cabinet 1 to be detachable in five directions, facilitating the debugging, maintenance, or replacement of internal structural components. Of course, if necessary, not all of the top cover 11, front door panel 12, rear door panel 13, left door panel, and right door panel 14 may be present.

[0081] like Figure 8As shown, the cabinet 1 also includes an air inlet plate 15, which is detachably connected to the frame 16. The air inlet plate 15 is opposite to the air inlet 21, and has multiple ventilation holes that communicate with the air inlet 21. The multiple ventilation holes on the air inlet plate 15 allow air to enter the air inlet 21 evenly. Simultaneously, the air inlet plate 15 can form a filter mesh structure, enabling the filtration of larger dust impurities in the air, thus initially filtering the air entering the environmental control equipment. If the filter device in the second chamber 4 is also used to filter particulate matter, the filtration capacity of the air inlet plate 15 is lower than that of the filter device in the second chamber 4.

[0082] like Figure 2 As shown, the environmental control equipment also includes a damper assembly 9 and a duct assembly 10. The damper assembly 9 is connected to the end of the second cavity 4 away from the fan cavity 3. Exemplarily, the damper assembly 9 can be screwed onto the second cavity 4, thus facilitating its assembly. The duct assembly 10 is connected to the end of the damper assembly 9 away from the second cavity 4, and the end of the duct assembly 10 away from the damper assembly 9 is connected to the air outlet 111. The damper assembly 9 is used to control the airflow, direction, and pressure. Exemplarily, by changing the opening angle of the damper blades, the airflow through the duct assembly 10 can be increased or decreased, thereby achieving precise control of the supply or exhaust air volume in different areas. The duct assembly 10 has a cylindrical structure and can guide air to the air outlet 111.

[0083] The top of the air duct assembly 10 is typically connected to the upper cover plate 11 by screws, and the internal space of the air duct assembly 10 is connected to the air outlet 111. The bottom of the air duct assembly 10 can be connected and fixed to the air valve assembly 9, thereby facilitating the assembly and disassembly of the air duct assembly 10.

[0084] Figure 9 This is a front view of the environmental control equipment provided in the embodiments of this application. Figure 10 for Figure 9 The sectional view at BB. Figure 10 The middle arrow indicates the path of airflow, such as... Figure 10 As shown, in one application example, air can enter the first cavity 2 through the air inlet 21, undergo heat exchange through the heat exchange module 5, and then be heated by the first heating component 81. The fan 7 can guide the heated air into the fan cavity 3, where it is reheated by the second heating component 82. Then, the fan 7 sends the heated air into the filter device in the second cavity 4, allowing the air to be filtered. The filtered air is then discharged from the air outlet 111 through the air valve assembly 9 and the air duct assembly 10 in sequence.

[0085] like Figure 10As shown, the environmental control equipment also includes a piping module 20, which can be disposed in the first cavity 2 and is positioned between the heat exchange module 5 and the front door panel 12 along the first direction X. The piping module 20 can provide a liquid working medium, which can be water, to the heat exchange module 5 to realize its heat exchange function.

[0086] Figure 11 This is a schematic diagram of the structure of the heat exchange module 5 in the environmental control equipment provided in the embodiments of this application, as shown below. Figure 11 As shown, the heat exchange module 5 may include a heat exchange cavity 51 and a heat exchanger 52. The heat exchanger 52 is installed in the heat exchange cavity 51 and may be installed at an angle or vertically in the heat exchange cavity 51, as shown in the attached figure. Figure 10 The heat exchanger 52 is positioned at approximately a 45-degree angle within the heat exchange chamber 51, closer to the air inlet 21, to facilitate the arrangement of the first heating element 81. The heat exchanger 52 can be connected to... Figure 10 The pipeline module 20 shown is connected so that the liquid working fluid can circulate between the heat exchanger 52 and the pipeline module 20 to achieve continuous heat exchange with the air.

[0087] The pipeline module 20 is located between the heat exchange module 5 and the front door panel 12, which facilitates the assembly of the pipeline module 20 and the heat exchanger 52, and also facilitates the daily maintenance of the pipeline module 20.

[0088] Figure 12 This is a partial structural diagram of an environmental control device provided in one embodiment of this application, as shown below. Figure 3 and Figure 12 As shown, a positioning guide 22 can be provided in the first cavity 2, and an installation port 23 is also provided on the first cavity 2. The heat exchange module 5 is slidably connected to the positioning guide 22 through the installation port 23. With the cooperation of the positioning guide 22, the heat exchange module 5 can be installed into the first cavity 2 from the installation port 23 by pulling it out, or pulled out from the first cavity 2, thus facilitating the disassembly and assembly of the heat exchange module 5.

[0089] The heat exchange module 5 also includes a heat exchange chamber cover plate 53. One end of the heat exchange chamber 51 has an opening, which facilitates the installation of the heat exchanger 52. After the heat exchanger 52 is installed into the heat exchange chamber 51, the heat exchange chamber cover plate 53 can be fastened to the opening to protect the heat exchanger 52.

[0090] Since the fan 7 and the second heating component 82 are integrated in the fan cavity 3, and the first heating component 81 is located in the first cavity 2 near the fan cavity 3, the first heating component 81, the fan 7, and the second heating component 82 are arranged sequentially from bottom to top as described above. For easy connection with the fan 7 and each heating component, such as... Figure 10 and Figure 12As shown, the electrical control module 6 of the environmental control equipment can be installed in the fan cavity 3, and the electrical control module 6 is positioned between the fan 7 and the front door panel 12 along the first direction X. Furthermore, by positioning the electrical control module 6 between the fan 7 and the front door panel 12 along the first direction X, the electrical control module 6 is located in a position easily accessible to the operator after the front door panel 12 is opened, thus facilitating the operator's control of the electrical control module 6.

[0091] Figure 13 This is a partial structural diagram of an environmental control device provided in another embodiment of this application, viewed from one perspective. Figure 14 This is a partial structural schematic diagram of an environmental control device provided in another embodiment of this application from another perspective, as shown below. Figure 13 and Figure 14 As shown, the second cavity 4 includes a detachable first cover plate 42 and a second cover plate 43, which are disposed on opposite sides of the second cavity 4 along a first direction X. The first cover plate 42 can be located on the side of the second cavity 4 closer to the front door panel 12, and the second cover plate 43 can be located on the side of the second cavity 4 closer to the rear door panel 13. When maintenance of the filter device inside the second cavity 4 is required, the corresponding first cover plate 42 or second cover plate 43 can be removed, facilitating operation.

[0092] like Figure 14 As shown, the fan cavity 3 includes a detachable third cover plate 31, which is disposed on one side of the fan cavity 3 along the first direction X. In this embodiment, the third cover plate 31 can be disposed on the side of the fan cavity 3 near the rear door panel 13. When maintenance is required on the fan 7 or the second heating component 82 inside the fan cavity 3, the third cover plate 31 can be removed, which facilitates the operation.

[0093] Therefore, in this embodiment, by providing corresponding detachable covers on the second cavity 4 and the fan cavity 3, when maintaining the filter device, heating device 8, sensor, electrical module, etc. in the second cavity 4 or the fan cavity 3, it is only necessary to remove the corresponding cover, which facilitates the operation.

[0094] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
