Description

Technical Field

[0001] This invention relates to the field of environmental testing equipment technology, and in particular to a temperature and humidity environmental testing device with integrated partition air supply. Background Technology

[0002] Temperature and humidity environmental testing equipment is a type of testing device used to simulate different temperature and humidity conditions. It is widely used in product quality inspection and reliability testing in fields such as electronics, pharmaceuticals, chemicals, and materials. This type of device provides the necessary environmental conditions for test samples by precisely controlling the temperature and humidity parameters inside the chamber and maintaining them uniformly and stably within the effective working space. This allows for the evaluation of the samples' performance changes, service life, and reliability indicators under different temperature and humidity environments.

[0003] In related technologies, existing temperature and humidity environmental testing equipment typically uses top-down or rear-down airflow to achieve airflow circulation within the chamber. After being processed by heating, cooling, or humidifying components, the airflow is delivered through ducts located at the top of the chamber or the main duct at the back, then enters the working area via air outlets or diffusers, and finally returns to the regulating components through the return air inlet, forming a cycle. This airflow method is a relatively common structural form in the field of environmental testing equipment, and its airflow path is relatively fixed, enabling a certain degree of temperature and humidity control within the chamber.

[0004] However, due to the centralized air supply structure, the airflow needs to travel a long path to reach all locations in the working area. During the delivery process, it is easily affected by local resistance, resulting in differences in temperature and humidity in different areas inside the chamber, especially in areas far from the air outlet, where dead air zones can easily form. The problem of insufficient temperature and humidity uniformity directly affects the accuracy and repeatability of the test results, making it difficult to meet the requirements of high-precision testing for a consistent environment inside the chamber. Summary of the Invention

[0005] The present invention aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this invention is to propose a temperature and humidity environment test device with integrated partition air supply. By integrating the air supply function into the partition, the airflow after temperature and humidity adjustment is directly sent to each partition through the distribution unit and then evenly discharged to the working area. This solves the problems of uneven airflow distribution and dead zones in the prior art, realizes direct air supply between layers, and improves the uniformity of temperature and humidity in the chamber.

[0007] To achieve the above objectives, the present invention proposes a temperature and humidity environment testing device with integrated partition air supply, comprising: A housing having an upper cavity and a lower cavity; An airflow processing unit, located inside the housing, is used for temperature and humidity control of the air. A distribution unit, located inside the housing and connected to the airflow processing unit, is used to receive and distribute the temperature- and humidity-controlled airflow. At least one partition is detachably installed inside the housing, the partition having an internal airflow channel and an air outlet structure communicating with the internal airflow channel; The distribution unit has air outlets corresponding to the positions of each partition. When the partition is installed in place, the air outlets are connected to the internal airflow channels of the partition.

[0008] In addition, the temperature and humidity environment testing device with integrated partition air supply according to the present invention may also have the following additional technical features: Specifically, the feature is that the lower cavity is provided with working components, which include a cooling module, a humidifying module and a control motherboard.

[0009] Specifically, the airflow processing unit is characterized by comprising: A lower sealing plate is disposed between the upper cavity and the lower cavity. The lower sealing plate has a hollow structure and an air inlet hole communicating with the upper cavity is opened at its top, forming an air mixing chamber inside. An airflow driving device is disposed in or connected to the air mixing chamber.

[0010] Specifically, the distribution unit is a back plate disposed at the rear of the upper cavity. The back plate has a hollow structure and forms an equalizing cavity inside it. The equalizing cavity is connected to the air mixing cavity.

[0011] Specifically, the feature is that the air outlet of the back panel is provided with an openable and closable baffle, which closes the air outlet in its natural state. The partition is equipped with a trigger. When the partition is installed in place, the trigger pushes against the baffle, causing the air outlet to open and connecting the equalizing chamber with the internal airflow channel of the partition.

[0012] Specifically, the baffle is characterized in that it is kept closed by magnetic attraction or gravity.

[0013] Specifically, the trigger element is characterized by being one of a pin, a protrusion, or a lever.

[0014] Specifically, the airflow driving device is a forward and reverse rotating fan. When the fan rotates forward, the airflow is sent into the upper cavity through the partition. When the fan rotates in reverse, the airflow is drawn into the air mixing chamber from the upper cavity through the partition.

[0015] Specifically, the device is characterized by being one of a constant temperature and humidity chamber, a high and low temperature test chamber, a drug stability test chamber, an incubator, or an aging test chamber.

[0016] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: 1. The present invention provides a temperature and humidity environment testing device with integrated partition air supply. By integrating the air supply function into the partition, the airflow after temperature and humidity adjustment is directly sent to each partition through the distribution unit and then evenly discharged to the working area. This solves the problems of uneven airflow distribution and dead zones in the prior art, realizes direct air supply between layers, and improves the uniformity of temperature and humidity in the chamber.

[0017] 2. The temperature and humidity environment test device with integrated partition air supply of the present invention, by setting up an openable and closable baffle and a trigger, realizes that the air outlet automatically opens when the partition is installed and automatically closes when the partition is removed, thereby avoiding ineffective airflow leakage and improving airflow distribution efficiency.

Detailed Implementation

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The following description, in conjunction with the accompanying drawings, describes a temperature and humidity environment testing device for integrated partition air supply according to an embodiment of the present invention.

[0022] like Figure 1 - Figure 7 As shown, an embodiment of the present invention provides a temperature and humidity environment testing device for integrated partition air supply, comprising: Box 1, which has an upper cavity 11 and a lower cavity 12; An airflow handling unit, located inside housing 1, is used for temperature and humidity control of the air. The distribution unit, located inside the housing 1, is connected to the airflow processing unit and is used to receive and distribute the temperature- and humidity-controlled airflow. At least one partition 4 is detachably installed inside the housing 1. The partition 4 has an internal airflow channel 41 and an air outlet structure 42 connected to the internal airflow channel 41. An air outlet 32 ​​is provided on the distribution unit corresponding to the position of each partition 4. When the partition 4 is installed in place, the air outlet 32 ​​is connected to the internal airflow channel 41 of the partition 4.

[0023] It should be noted that the housing 1 is the external support structure of the device, used to house and protect the internal functional components. The interior of the housing 1 is divided into two areas, an upper cavity 11 and a lower cavity 12, by a horizontally arranged molded structure.

[0024] The upper chamber 11 is the test work area, used to place the sample to be tested and to control the temperature and humidity. The lower chamber 12 is located at the bottom of the chamber 1 and is used to accommodate the working accessories 5.

[0025] The upper cavity 11 is provided with an openable glass door at the front, and a sealing strip is installed around the glass door to seal the upper cavity 11 when closed, so as to maintain the stability of the internal environment.

[0026] Preferably, the entire housing 1 is made of spliced ​​metal sheets, and the inner and outer surfaces are treated with anti-corrosion to ensure its structural stability and durability in high temperature and high humidity environments.

[0027] The airflow handling unit is a functional module located within chamber 1, used for temperature and humidity control of the circulating air. It includes heating, cooling, and humidifying components, and can heat, cool, humidify, or dehumidify the air according to set parameters to achieve the required temperature and humidity conditions for the experiment. The airflow handling unit works in conjunction with the airflow drive device 23 within chamber 1 to ensure that the air is adequately processed during circulation.

[0028] Preferably, the heating component uses an electric heating element, the cooling component uses a compression or semiconductor cooling system, and the humidification component uses an electrode, heating wire, heating tube, ultrasonic, or other humidifier.

[0029] The distribution unit is an airflow distribution structure located inside the housing 1 and is connected to the airflow processing unit. The distribution unit has an internal cavity for receiving the air that has been conditioned and humidified by the airflow processing unit and distributing it evenly to different delivery paths.

[0030] Preferably, the distribution unit is made of welded or spliced ​​metal plates, and its internal flow guiding structure can be set to reduce airflow resistance.

[0031] The partition 4 is a multi-layered load-bearing structure installed inside the upper cavity 11, and is detachably fixed to the support members on both sides of the box 1. The partition 4 is used to place test samples and has the function of supporting samples. The partition 4 has a hollow internal airflow channel 41, and the surface of the partition 4 has an air outlet structure 42 that communicates with the internal airflow channel 41.

[0032] The air outlet structure 42 can be multiple air outlet holes 32 or air outlet gaps opened on the upper surface, lower surface or side of the partition 4, so that the airflow entering the partition 4 can be evenly diffused to the working area of ​​the upper cavity 11.

[0033] Preferably, the partition 4 is made of metal material through an extrusion molding process, and the internal airflow channel 41 extends along the length of the partition 4.

[0034] Preferably, the partition 4 is made of metal material through a bending and welding process, and the internal airflow channel 41 is formed by the upper and lower plates and the side plates.

[0035] The air outlet 32 ​​is opened on the side of the distribution unit facing the partition 4, and its position corresponds to the installation position of each layer of partition 4. When the partition 4 is installed in the upper cavity 11, the air outlet 32 ​​is connected to the inlet end of the internal airflow channel 41 of the partition 4, so that the airflow in the distribution unit can enter the partition 4 through the air outlet 32.

[0036] In this embodiment, the partition 4 and the distribution unit adopt a non-contact docking structure. After the partition 4 is installed in place, its rear end fits against the front surface of the distribution unit, so that the air outlet 32 ​​is naturally connected to the internal airflow channel 41.

[0037] Specifically, after the airflow drive device 23 is activated, the air inside the chamber 1 enters the airflow processing unit for temperature and humidity control. The treated air then enters the distribution unit, where it is collected and evenly distributed. The air in the distribution unit enters the corresponding partition 4 through the air outlets 32 of each layer, flowing into the internal airflow channel 41 of the partition 4. After flowing within the internal airflow channel 41, the air is evenly diffused to the working area of ​​the upper cavity 11 via the air outlet structure 42 on the surface of the partition 4, thus controlling the temperature and humidity of the sample placed on the partition 4. The treated air continues to flow and re-enters the airflow processing unit, forming a continuous cycle.

[0038] In one embodiment of the present invention, a working component 5 is provided in the lower cavity 12, the working component 5 including a cooling module, a humidifying module and a control main board.

[0039] It should be noted that the lower cavity 12 is located at the bottom of the housing 1 and is used to accommodate the working parts 5. The lower cavity 12 is separated from the upper cavity 11 by the lower sealing plate 2, forming a relatively independent installation space, which facilitates the centralized layout and maintenance of each working part 5.

[0040] Working component 5 includes a refrigeration module, a humidification module, and a control mainboard. The refrigeration module is used to cool or dehumidify the circulating air, and it includes a compressor, condenser, and evaporator, achieving heat exchange through refrigerant circulation.

[0041] Preferably, the refrigeration module uses a fully enclosed compressor, and the evaporator is located in the airflow handling unit and is in direct contact with the air.

[0042] The humidification module is used to humidify the circulating air. It includes a humidifier and a water supply device, which increases the air humidity by generating water vapor or water mist.

[0043] Preferably, the humidification module uses an electrode-type humidifier or an ultrasonic humidifier. The control motherboard is used to receive sensor signals and control the operating status of each working component 5. It includes a microprocessor, a storage unit, and input / output interfaces, and adjusts the temperature and humidity parameters inside the chamber 1 through a preset control algorithm.

[0044] Preferably, the control motherboard integrates a temperature and humidity acquisition module, which is electrically connected to the temperature and humidity sensor located in the upper cavity 11.

[0045] Specifically, the refrigeration module, humidification module, and control mainboard are fixedly installed in different positions within the lower cavity 12, with appropriate spacing between each component to ensure heat dissipation and maintenance space. The compressor section of the refrigeration module is located in the rear area of ​​the lower cavity 12, the humidification module is located in the side area of ​​the lower cavity 12, and the control mainboard is located in the front area of ​​the lower cavity 12 for easy operation and debugging. The working accessory 5 is connected to the airflow handling unit and related components in the upper cavity 11 via pipes and wiring to achieve precise control of the temperature and humidity inside the chamber 1.

[0046] In one embodiment of the present invention, the airflow processing unit includes: The lower sealing plate 2 is disposed between the upper cavity 11 and the lower cavity 12. The lower sealing plate 2 has a hollow structure and an air inlet 21 communicating with the upper cavity 11 is opened on its top, forming an air mixing chamber 22 inside. The airflow drive device 23 is disposed in or connected to the air mixing chamber 22.

[0047] It should be noted that the lower sealing plate 2 is a partition structure installed between the upper cavity 11 and the lower cavity 12. As a component of the airflow handling unit, the lower sealing plate 2 has a hollow structure, forming a closed cavity inside to accommodate and guide airflow. Multiple air inlets 21 are provided on the top of the lower sealing plate 2, and these inlets 21 are connected to the upper cavity 11, allowing air from the upper cavity 11 to enter the lower sealing plate 2 through the air inlets 21.

[0048] Preferably, the lower sealing plate 2 is made of metal sheet by stamping or welding process, and the air inlet 21 is circular or elongated and is evenly distributed on the top plate of the lower sealing plate 2.

[0049] An air mixing chamber 22 is formed inside the lower sealing plate 2. This air mixing chamber 22 is used to mix and regulate the temperature and humidity of the air. Air enters the air mixing chamber 22 from the upper cavity 11 through the air inlet 21. The air mixing chamber 22 has a certain volume, which allows the incoming air to stay in the chamber briefly and mix thoroughly, reducing the unevenness of temperature and humidity.

[0050] The airflow drive device 23 is used to drive air to circulate within the housing 1. It is installed in or connected to the air mixing chamber 22. When the airflow drive device 23 is running, it generates negative pressure, causing air to be drawn into the air mixing chamber 22 from the air inlet 21 and discharged from the outlet of the air mixing chamber 22 after processing, entering the distribution unit.

[0051] In one embodiment of the present invention, the distribution unit is a back plate 3, which is disposed at the rear of the upper cavity 11. The back plate 3 has a hollow structure and forms an equalizing cavity 31 inside it. The equalizing cavity 31 is connected to the air mixing cavity 22.

[0052] It should be noted that the back plate 3 is a plate-shaped structure located at the rear of the upper cavity 11, and is a specific implementation of the distribution unit. The back plate 3 has a hollow structure, and its interior forms a closed cavity, which is the pressure equalization cavity 31.

[0053] The equalizing chamber 31 is used to receive air from the airflow handling unit and use its volume to form a stable static pressure in the chamber, thereby achieving uniform distribution of air outlets on each layer.

[0054] Preferably, the back plate 3 is made of metal sheet by stamping, and its external dimensions match the rear opening of the upper cavity 11. After installation, it forms an integral part with the rear wall of the upper cavity 11.

[0055] The equalizing chamber 31 is connected to the air mixing chamber 22, allowing the air processed by the air mixing chamber 22 to enter the equalizing chamber 31. The equalizing chamber 31 ensures that the incoming air is delivered to each layer only after the pressure has reached equilibrium, reducing uneven distribution caused by airflow pulsation or pressure fluctuations. Multiple air outlets 32 are provided on the back plate 3, located on the front surface of the back plate 3, facing the partition 4. The positions of the air outlets 32 correspond to the installation positions of each partition 4, ensuring that each partition 4 has one or more air outlets 32 after installation. The size of the air outlets 32 is set according to the airflow distribution requirements. Preferably, the multiple air outlets 32 are arranged in an array or layered distribution on the back plate 3.

[0056] In one embodiment of the present invention, an openable and closable baffle 33 is provided at the air outlet 32 ​​of the back plate 3, and the baffle 33 closes the air outlet 32 ​​in a natural state. The partition 4 is provided with a trigger 43. When the partition 4 is installed in place, the trigger 43 pushes against the baffle 33, causing the air outlet 32 ​​to open and connecting the equalizing chamber 31 with the internal airflow channel 41 of the partition 4.

[0057] It should be noted that the baffle 33 is a movable part installed at the air outlet 32 ​​of the back plate 3, used to control the opening and closing of the air outlet 32. In its natural state, the baffle 33 covers the inside of the air outlet 32, keeping the air outlet 32 ​​closed and preventing the airflow in the equalizing chamber 31 from escaping when the partition 4 is not installed.

[0058] The baffle 33 is made of lightweight material, with one end connected to the back plate 3 and the other end being a free end that can rotate or swing around the connection point. Preferably, the baffle 33 is made of plastic or thin metal sheet, and its shape and size match the air outlet 32 ​​to ensure airtightness when closed.

[0059] The trigger 43 is a protruding component mounted on the partition 4, used to apply force to the baffle 33 during the installation of the partition 4. The trigger 43 is located at the rear end of the partition 4, that is, on the side facing the back plate 3, and its position corresponds to the air outlet 32 ​​on the back plate 3.

[0060] The trigger 43 is made of a rigid material and has a certain height and strength, enabling it to contact the baffle 33 and push it to move when the partition 4 is pushed in. Preferably, the trigger 43 is integrally formed with the partition 4, and its front end is arc-shaped or conical to reduce resistance during pushing.

[0061] When the partition 4 is installed, the operator pushes it horizontally into the installation position within the upper cavity 11. As the partition 4 moves backward, the trigger 43 at its rear end gradually approaches the baffle 33 on the back plate 3. When the partition 4 is in place, the trigger 43 pushes against the baffle 33, causing the baffle 33 to rotate or swing around its connection point, thereby opening the air outlet 32. At this time, the equalizing chamber 31 is connected to the internal airflow channel 41 of the partition 4 through the opened air outlet 32, allowing airflow to enter the interior of the partition 4 from the equalizing chamber 31.

[0062] In this embodiment, the baffle 33 remains closed by gravity or its own elasticity when no external force is applied. When the partition 4 is removed, the trigger 43 moves forward with the partition 4 away from the baffle 33, and the baffle 33 resets after losing external support, thereby sealing the air outlet 32. This installation method ensures that the air outlet 32 ​​is only open at the location where the partition 4 is installed, while the location where the partition 4 is not installed remains closed, preventing airflow leakage and improving the efficiency and control accuracy of airflow distribution.

[0063] In one embodiment of the present invention, the baffle 33 is kept closed by magnetic attraction 34 or by gravity.

[0064] It should be noted that the baffle 33 can remain closed in its natural state in two ways: by the action of the magnetic attraction 34 or by gravity.

[0065] The magnetic attractor 34 is an auxiliary component used to keep the baffle 33 in a closed state. When using the magnetic attractor method, the magnetic attractor 34 includes a first magnetic element mounted on the baffle 33 and a second magnetic element mounted at a corresponding position on the back plate 3, or a structure consisting of a single magnetic element and a ferromagnetic material. In its natural state, the magnetic force generated by the magnetic attractor 34 keeps the baffle 33 tightly attached to the air outlet 32, maintaining a closed state. When the partition 4 is installed in place, the force of the trigger 43 pushing against the baffle 33 overcomes the magnetic attraction force, causing the baffle 33 to open. When the partition 4 is removed, the trigger 43 leaves, and the baffle 33 automatically resets and closes under the action of the magnetic attractor 34. Preferably, the first magnetic element and the second magnetic element are permanent magnets, or one of them is a permanent magnet and the other is a ferromagnetic metal sheet.

[0066] The gravity-based method refers to the method in which the baffle 33 remains closed by its own weight. In this method, the upper end of the baffle 33 is hinged to the back plate 3 or suspended by a flexible connector, and its center of gravity is located below the hinge point. In its natural state, the baffle 33 hangs down naturally under the action of gravity, covering and closing the air outlet 32. When the partition 4 is installed, the trigger 43 pushes against the lower part of the baffle 33, causing the baffle 33 to overcome gravity and rotate upward or sideways around the hinge point, thereby opening the air outlet 32. When the partition 4 is removed, the trigger 43 leaves, and the baffle 33 automatically resets under the action of gravity, re-closing the air outlet 32. Preferably, a counterweight is installed at the lower end of the baffle 33 to ensure the reliability of the closure.

[0067] In one embodiment of the present invention, the trigger 43 is one of a pin, a protrusion, or a lever.

[0068] It should be noted that the trigger 43 is a protruding structure at the rear end of the mounting partition 4, used to contact the baffle 33 and push it open during the installation of the partition 4. The trigger 43 can be implemented in various structural forms.

[0069] When the trigger 43 is in the form of a pin, it has a slender rod-like structure that extends horizontally from the rear end of the partition 4. The front end of the pin is fixedly connected to the partition 4, while the rear end is a free end and is arc-shaped or conical to reduce friction and impact when in contact with the baffle 33. The length of the pin is selected according to the gap between the partition 4 and the back plate 3 to ensure that the pin can push the baffle 33 to the fully open position when the partition 4 is installed in place. Preferably, the pin is made of metal and is fixed to the partition 4 by thread or embedded connection.

[0070] When the trigger element 43 is in the form of a protrusion, it has a block structure and is integrally formed or fixedly connected to the rear end face of the partition 4. The rear end face of the protrusion is a flat surface or a curved surface, used to contact the baffle 33. The height and width of the protrusion are selected according to the size of the air outlet 32 ​​and the position of the baffle 33 to ensure that the protrusion can accurately act on the baffle 33 and push it open when the partition 4 is installed. Preferably, the protrusion and the partition 4 are integrally formed from the same material, such as forming the protrusion structure simultaneously during aluminum alloy extrusion molding.

[0071] When the trigger 43 is in the form of a lever, it has a lever-like structure, including a base connected to the partition 4 and an outwardly extending actuating part. The base of the lever is connected to the partition 4 via a pivot or flexible connection, and the actuating part is used to contact the baffle 33. The lever can be made of an elastic material, and the actuating part can deform under force during the installation of the partition 4, reducing the rigid impact on the baffle 33. Preferably, the lever is made of plastic or spring steel sheet, and its end is provided with a roller or a smooth curved surface to reduce friction.

[0072] In this embodiment, regardless of whether the trigger 43 is in the form of a pin, a protrusion or a lever, its function is to apply a pushing force to the baffle 33 when the partition 4 is installed in place, so that the baffle 33 overcomes the holding force and opens the air outlet 32.

[0073] In one embodiment of the present invention, the airflow drive device 23 is a forward and reverse fan. When the fan rotates forward, the airflow is sent into the upper cavity 11 through the partition 4. When the fan rotates in reverse, the airflow is drawn into the air mixing chamber 22 from the upper cavity 11 through the partition 4.

[0074] It should be noted that the airflow drive device 23 is a forward and reverse fan, that is, the fan has two operating modes: forward and reverse. It can change the rotation direction of the impeller according to the control command, thereby realizing the flow of air in different directions within the housing 1.

[0075] When the fan rotates forward, the impeller rotates in the first direction, generating an airflow driving force from the air mixing chamber 22 to the pressure equalization chamber 31. In this mode, air is drawn into the air mixing chamber 22 from the upper chamber 11 through the air inlet 21. After temperature and humidity adjustment in the air mixing chamber 22, it is pushed by the fan to the pressure equalization chamber 31, and then enters the internal airflow channel 41 of the partition 4 through the air outlet 32. Finally, it is evenly delivered into the working area of ​​the upper chamber 11 through the air outlet structure 42, thereby achieving temperature and humidity control on the sample placed on the partition 4.

[0076] When the fan reverses direction, the impeller rotates in the opposite direction to the forward rotation, generating an airflow driving force from the upper cavity 11 towards the air mixing chamber 22. In this mode, the airflow direction is opposite to that during forward rotation. The air in the upper cavity 11 is drawn into the internal airflow channel 41 through the air outlet structure 42 of the baffle 4, then enters the equalization chamber 31 through the air outlet 32, and is then drawn back into the air mixing chamber 22 by the fan. Finally, it is discharged into the upper cavity 11 through the air inlet 21, forming a reverse circulation.

[0077] Preferably, the forward and reverse fan adopts a bidirectional centrifugal fan or a bidirectional axial fan, whose motor can accept bidirectional power supply control to realize the switching of impeller rotation direction. The fan speed and direction are adjusted by the control motherboard according to preset program or real-time command.

[0078] In one embodiment of the present invention, the device is one of a constant temperature and humidity chamber, a high and low temperature test chamber, a drug stability test chamber, an incubator, or an aging test chamber.

[0079] When using this device, first, place the test samples on each layer of partition 4 according to the experimental requirements. Adjust the number of layers and the spacing between layers of partition 4 according to the number and size of the samples. Push the partition 4 horizontally into the upper cavity 11, with the rear end of the partition 4 adhering to the front surface of the back plate 3. At this time, the trigger 43 on the partition 4 pushes against the baffle 33 at the air outlet 32 ​​of the back plate 3, causing the baffle 33 to open against the magnetic force or gravity of the magnetic attraction 34, and the air outlet 32 ​​connects with the internal airflow channel 41 of the partition 4. Close the glass door and ensure the airtightness of the upper cavity 11 through the sealing strip.

[0080] When the airflow drive device 23 is activated, it generates negative pressure, causing the air in the upper cavity 11 to be drawn into the air mixing chamber 22 through the air inlet 21 at the top of the lower sealing plate 2. The air flows in the air mixing chamber 22 and comes into contact with the heating, cooling and humidifying components installed in the chamber. The air is heated, cooled, humidified or dehumidified according to the set parameters to make the air reach the temperature and humidity conditions required for the test. The treated air is discharged from the outlet of the air mixing chamber 22 under the action of the airflow drive device 23 and enters the pressure equalization chamber 31 of the back plate 3.

[0081] After the air enters the equalizing chamber 31, a stable static pressure is formed in the chamber, reducing the uneven distribution caused by airflow pulsation or pressure fluctuation. The air in the equalizing chamber 31 enters the corresponding partition 4 through the air outlet 32 ​​of each layer and flows into the internal airflow channel 41 of the partition 4. After flowing in the internal airflow channel 41, the air is evenly diffused to the working area of ​​the upper cavity 11 through the air outlet structure 42 on the surface of the partition 4, which affects the temperature and humidity of the sample placed on the partition 4. After the effect, the air is driven by the airflow driving device 23 and enters the air mixing chamber 22 again through the air inlet 21 at the top of the lower sealing plate 2, forming a continuous cycle.

[0082] When it is necessary to adjust the layout of the partition 4 or remove the sample, open the glass door and pull the partition 4 forward. During the movement of the partition 4, the trigger 43 leaves the baffle 33, and the baffle 33 automatically resets under the magnetic force or gravity of the magnetic suction component 34, resealing the air outlet 32 ​​to prevent the airflow in the equalizing chamber 31 from escaping. When rapid dehumidification, drying, or simulation of specific environmental conditions is required, switch the airflow drive device 23 to reverse mode. The fan reverses, causing the airflow direction to be reversed. The air in the upper cavity 11 is drawn into the internal airflow channel 41 through the air outlet structure 42 of the partition 4, then enters the equalizing chamber 31 through the air outlet 32, and is then drawn back into the air mixing chamber 22 by the fan. Finally, it is discharged into the upper cavity 11 through the air inlet 21, forming a reverse circulation.

[0083] In summary, the temperature and humidity environmental testing device with integrated partition and air supply according to this invention solves the problems of uneven airflow distribution and dead zones in the prior art by integrating air supply function between partitions. This allows the temperature- and humidity-controlled airflow to be directly delivered to each partition via a distribution unit and then evenly distributed to the working area. This achieves direct air supply between layers and improves the uniformity of temperature and humidity within the chamber. Furthermore, by incorporating openable and closable baffles and triggers, the air outlets automatically open when partitions are installed and automatically close when partitions are removed, preventing ineffective airflow leakage and improving airflow distribution efficiency.

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.
