Description

Technical Field

[0001] The utility model relates to the technical field of simulated environment test boxes, in particular to an air supply structure and a test box. Background Art

[0002] The test chamber, also known as the simulated climate environment test chamber, can simulate one or more climate and environmental conditions in nature. It is mainly used to test the product's resistance to high and low temperatures, humidity, etc. It is an essential testing equipment in the fields of aviation, automobiles, home appliances, scientific research, etc.

[0003] The test box in the prior art generally includes a partition, a constant temperature and humidity system, an air supply port and a return air port. The partition divides the test box into a test room and a control room. The test room is used to place the test product, and the control room is used to place the constant temperature and humidity system. The constant temperature and humidity system provides a certain temperature and humidity environment to the test room through the air supply port for testing the test product. The air in the test room is circulated to the control room again through the return air port.

[0004] In order to ensure the consistency of temperature and humidity in all parts of the test room, the air outlet of the test chamber currently often uses both horizontal and vertical air regulating plates, and the two are set closely together in the air supply structure, so that the transported airflow can be transported horizontally and vertically, thereby ensuring the consistency of temperature and humidity at different locations in the entire test room.

[0005] Since the horizontal air regulating plates and the vertical air regulating plates are set close to each other, more stringent test conditions are required for the consistency of temperature and humidity at different positions in the test room. This structural form has limitations. For example, the air volume obtained at the position far away from the air outlet is relatively small, and the temperature and humidity difference with other areas is relatively large, which cannot meet the more stringent test conditions.

[0006] Therefore, the above problems need to be solved urgently. Utility Model Content

[0053] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the convenience of description, only the parts related to the present utility model are shown in the drawings, rather than all the structures.

The first feature being "below", "under" and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0056] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0057] To ensure the consistency of the temperature and humidity in the test chamber, so as to meet more stringent test conditions, a air supply structure for delivering air flow into the chamber (specifically referring to the test chamber in this embodiment) is proposed in this embodiment, to ensure that the delivered air flow can be delivered along two staggered directions in the test chamber, to ensure the consistency of the temperature and humidity at each position in the test chamber, and the air flows delivered along different directions do not interfere with each other.

[0058] Specifically, please refer to Figures 1 to 5 , the air supply structure 500 includes a first frame body 1, a second frame body 3, a plurality of first air regulating plates 2 and a plurality of second air regulating plates 4. The plurality of first air regulating plates 2 are arranged on the first frame body 1, and a first air supply flow channel is formed between two adjacent first air regulating plates 2; along the air supply direction, the second frame body 3 is inclined towards the center of the chamber and arranged on the downstream side of the first frame body 1; the plurality of second air regulating plates 4 are arranged on the second frame body 3, and a second air supply flow channel is formed between two adjacent second air regulating plates 4, and the length direction of the second air supply flow channel is arranged staggeredly with respect to the length direction of the first air supply flow channel.

[0059] It can be understood that along the air supply direction, the conveyed air flow first passes through multiple first air supply flow channels, so that it can be separated into multiple air flows, ensuring that the temperature and humidity at each position in the test chamber 110 along the arrangement direction of the first air supply flow channels can be kept consistent. Subsequently, the conveyed air flow passes through multiple second air supply flow channels, so that it can be separated into multiple air flows again. Also, since the second frame body 3 is inclined, it is ensured that the temperature and humidity at each position in the test chamber 110 along the arrangement direction of the second air supply flow channels can be kept consistent. That is, under the action of the first frame body 1, the second frame body 3, multiple first air regulating plates 2 and multiple second air regulating plates 4, it can be ensured that the temperature and humidity at each position in the test chamber 110 can be kept consistent.

[0060] In addition, since the first frame body 1 and the second frame body 3 are inclined, there is a gap between the first air supply flow channel and the second air supply flow channel. Therefore, the possibility of interference between the air flow in the first air supply flow channel and the air flow in the second air supply flow channel can be reduced or even avoided, further improving the consistency of the temperature and humidity in the test chamber 110.

[0061] Exemplarily, the length direction of any first air regulating plate 2 is arranged along the vertical direction of the test chamber 110, and multiple first air regulating plates 2 are evenly arranged along the horizontal direction of the test chamber 110. The space between two adjacent first air regulating plates can form a first air supply flow channel. That is, the length direction of the first air supply flow channel is arranged along the vertical direction of the test chamber 110, so that the conveyed air flow can be separated into multiple horizontally arranged first air flows, ensuring the consistency of the temperature and humidity at each position in the horizontal direction of the box. The length direction of any second air regulating plate 4 is arranged along the horizontal direction of the test chamber 110, and multiple second air regulating plates 4 are arranged obliquely along the vertical direction of the test chamber 110. That is, the length direction of the second air supply flow channel is arranged obliquely along the vertical direction of the test chamber 110. The first air flow is separated into multiple obliquely arranged second air flows by the second air supply flow channel, ensuring the consistency of the temperature and humidity at different height positions in the test chamber 110.

[0062] In addition, since the cross-sectional area of the first air flow is larger than that of the small air flow, the flow rate of the first air flow is lower than that of the small air flow. When the first air flow passes through the gap between the first frame body 1 and the second frame body 3, due to the increase in the overall space, the flow rate of the first air flow decreases. After the first air flow passes through the second air supply flow channel, although the flow rate will increase, compared with the initial flow rate of the air flow, the difference is not significant. Furthermore, the occurrence of turbulence between the first air flow and the second air flow can be avoided, further ensuring the consistency of the temperature and humidity at each position inside the test chamber 110.

[0063] In this embodiment, the first frame 1 includes a first fixing member 11 and a second fixing member 12 arranged in parallel; the second frame 3 includes a plurality of third fixing members 31, which are inclined between the first fixing member 11 and the second fixing member 12, and both ends of any one of the third fixing members 31 are respectively connected to the first fixing member 11 and the second fixing member 12. It can be understood that a cubic structure with a triangular cross-section is formed between the first frame 1 and the second frame 3, so as to facilitate the installation of the entire air supply structure 500 at the air supply opening 130.

[0064] When the central position of the test chamber 110 is above the air supply structure 500, the area of the first fixing member 11 is smaller than the area of the second fixing member 12, so that the second frame 3 can be inclined upward. Correspondingly, when the central position of the test chamber 110 is below the air supply structure 500, the area of the first fixing member 11 is larger than the area of the second fixing member 12, so that the second frame 3 can be inclined downward.

[0065] It should be noted that the number of the third fixing members 31 in this embodiment is three. In some other feasible embodiments, the number of the third fixing members 31 can be determined according to the actual working conditions and will not be elaborated here.

[0066] Both ends of any one of the first air regulating plates 2 are respectively connected to the first fixing member 11 and the second fixing member 12. Specifically, both ends of the first air regulating plate 2 are fixed to the first fixing member 11 and the second fixing member 12 by bolts, so as to facilitate the subsequent adjustment of the angle of the first air regulating plate 2, so as to adapt to more different working conditions and improve the applicability of the air supply structure 500. Among them, the first air regulating plate 2 is preferably a plate-like structure.

[0067] Both ends of any one of the second air regulating plates 4 are respectively connected between two adjacent third fixing members 31. Specifically, both ends of the second air regulating plate 4 are fixed between the two third fixing members 31 by bolts, so as to facilitate the subsequent adjustment of the angle of the second air regulating plate 4, so as to adapt to more different working conditions and improve the applicability of the air supply structure 500.

[0068] Among them, the second air regulating plate 4 includes an air regulating part 41 and a first connecting part 42. Along the air supply direction, the air regulating part 41 has a bend; the first connecting parts 42 are arranged on both sides of the air regulating part 41 to be connected to the third fixing members 31. The bending design of the air regulating part 41 is for the smoothness of the second air flow during transportation in the second air supply flow channel, and is also beneficial to adjusting the flow direction of the second air flow and the flow rate at different positions in the test chamber 110.

[0069] Based on the above, in this embodiment, an experimental chamber is further proposed, which includes a box body 100, a partition 200, a grid plate 300, a temperature and humidity control system 400, a fan and an air supply structure 500. The partition 200 is arranged inside the box body 100 to divide the interior of the box body 100 into a test chamber 110 and a control chamber 120. The partition 200 and the top and bottom walls of the box body 100 respectively form an air supply port 130 and a return air port 140 to connect the test chamber 110 and the control chamber 120. The grid plate 300 is arranged in the test chamber 110 to carry test vessels. The temperature and humidity control system 400 is arranged in the control chamber 120 to control the temperature and humidity in the test chamber 110. The fan is arranged in the control chamber 120 and is used to transport the air flow generated by the temperature and humidity control system 400 to the air supply port 130. The air supply structure 500 is arranged at the air supply port 130. The experimental chamber applicable to the above air supply structure 500 can ensure that the temperature and humidity in each part of the test chamber 110 are consistent.

[0070] The temperature and humidity control system 400 includes components such as an evaporator, a heater, and a humidifying pipe, which are used to form temperature and humidity conditions simulating the natural environment. The evaporator provides cold energy, the heater provides heat energy, the humidifying pipe provides humidity, and the air flow that meets the requirements is sent to the test chamber 110 through the fan, and then circulates back to the air-conditioning chamber through the return air port 140 on the return air plate.

[0071] When the temperature and humidity control system 400 transports air flow to the test chamber 110, due to a certain temperature difference between the internal temperature of the test chamber 110 and the temperature of the top of the box body 100, dew will condense on the top of the test chamber 110. If the dew drops into the test vessel, it will affect the entire test result. Therefore, in this embodiment, the experimental chamber further includes a temperature equalizing plate 600. The temperature equalizing plate 600 is arranged inside the box body 100 and forms a temperature equalizing cavity with the top wall. The temperature equalizing cavity has an air inlet 621 and an air outlet 622, and the air inlet 621 is directly opposite to a part of the air supply port 130, and the air outlet 622 is connected to the test chamber 110.

[0072] In practical applications, after the air flow is transported to the test chamber 110, a part of it can enter the temperature equalizing cavity, so that the temperature and humidity in the temperature equalizing cavity are the same as those in the test chamber 110. Even when the dew condensed on the top wall of the box body 100 is about to drip, it will be received by the temperature equalizing plate 600, thus avoiding the dew from entering the test vessel.

[0073] Specifically, the isothermal plate 600 includes a plate body 610, a partition portion 620, and a second connection portion. The partition portion 620 is disposed on the plate body 610 and can be attached to the top wall. The air inlet 621 and the air outlet 622 are both disposed on the partition portion 620. The second connection portion is used to connect the plate body 610 and the top wall. It can be understood that the plate body 610, the partition portion 620, and the top wall of the box body 100 can enclose an isothermal cavity to receive the dew that will drip, thereby further ensuring the accuracy of the test.

[0074] Among them, the partition portion 620 includes three plate members, and the three plate members are respectively disposed on three of the edges of the plate body 610. The edge where no plate member is disposed and the plate members on both sides form the air inlet 621, and the air outlet 622 is disposed on the plate member opposite to the air inlet 621.

[0075] In addition, the second connection portion includes a first connection unit and a second connection unit. The first connection unit is disposed on the top wall. The second connection unit is disposed on the plate body 610, and the first connection unit is adaptively connected to the second connection unit. Exemplarily, the first connection unit is a bolt, and the second connection unit is a nut adapted to the bolt. Such a setting facilitates the installation of the isothermal plate 600 and subsequent maintenance. Of course, in some other feasible embodiments, the second connection portion can also be other existing connection structures, which will not be elaborated here.

[0076] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
