[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: an airflow distribution and guiding device for a high and low temperature test chamber, including a guiding component 1. The guiding component 1 includes a plate 11, and the plate 11 is provided with a first compartment 12, a second compartment 14, and a third compartment 15. A heat insulation plate 13 is provided between the second compartment 14 and the first compartment 12 and the third compartment 15. The heat insulation plate 13 can separate the temperatures inside the first compartment 12, the second compartment 14, and the third compartment 15 to avoid mutual interference. One end of the first compartment 12, the second compartment 14, and the third compartment 15 is provided with a through hole. One end of the plate 11 is provided with a first adjusting component 2, a second air outlet 3, and a second adjusting component 4. The second adjusting component 4 and the first adjusting component 2 are mirror images of each other about the bisector of the plate 11. As shown in the diagram, one end of the plate 11 has an open structure. This structure, through the second adjusting component 4 and the first adjusting component 2, can distribute the airflow to both sides, thereby ensuring the range of airflow distribution. The second air outlet 3 is connected to the through hole of the second sub-cavity 14. The second adjusting component 4 has the same structure as the first adjusting component 2. The first adjusting component 2 includes a first air outlet 25 movably connected to one end of the first sub-cavity 12. The first air outlet 25 has an inclined structure, and multiple first air outlets 25 are distributed horizontally at equal intervals about one end of the first sub-cavity 12. The angle of the first air outlet 25 in this structure can be adjusted to ensure the rationality of the airflow distribution position. Heating tubes 26 are fixedly connected inside both the first sub-cavity 12 and the third sub-cavity 15. The outer wall of the through hole of the first sub-cavity 12 is fixedly connected to... The sealing rubber 28, through the heating tube 26, heats the airflow entering the first chamber 12 and the third chamber 15, achieving airflow temperature compensation. This ensures that the airflow temperature distributed from the first outlet 25 is consistent with the airflow temperature distributed from the second outlet 3, improving the temperature uniformity in the high and low temperature test chamber. The first outlet 25 is fixedly connected to the inner side of the sealing rubber 28. The sealing rubber 28 is made of high-temperature resistant rubber. This structure, by setting the sealing rubber 28, ensures the seal at the connection between the first outlet 25 and the first chamber 12, while also allowing for a flexible connection between the first outlet 25 and the first chamber 12. This allows the first outlet 25 to move left and right to adjust its angle, thus facilitating adjustments to the first outlet 25 as needed. The angle can be adjusted to improve the uniformity of airflow distribution in this device. A connecting rod 29 is rotatably connected to the top of the first air outlet 25, and a push rod 24 is connected to the top of the connecting rod 29. The push rod 24 is slidably connected to the plate 11. By setting the connecting rod 29, the first air outlet 25 can be connected to the push rod 24, which facilitates the adjustment of the angle of the first air outlet 25. One end of the push rod 24 is fixedly connected to a lead screw slide 27. A threaded rod 23 is threadedly connected inside the lead screw slide 27. Fixed seats 22 are provided on both sides of the threaded rod 23. An adjusting motor 21 is installed on one side of the fixed seat 22. One end of the shaft of the adjusting motor 21 is connected to the shaft on one side of the threaded rod 23 through a coupling. This structure allows the adjusting motor 21 to drive the threaded rod 23 to rotate.During rotation, the threaded rod 23 drives the lead screw slide 27 to slide. The lead screw slide 27, during its movement, can push the push rod 24 to move laterally. The push rod 24, during its movement, can rotate the angle of the first air outlet 25, thus achieving automatic adjustment of the angle of the first air outlet 25. During installation, the plate 11 is installed on the inner wall of the high and low temperature test chamber, the adjusting motor 21 is installed on the outer wall of the high and low temperature test chamber, the fixed seat 22 is installed in the inner wall of the high and low temperature test chamber, and the push rod 24 is located on the inner wall of the high and low temperature test chamber but is not fixed to the chamber.

[0024] Working principle: When using the airflow distribution and guiding device of the high and low temperature test chamber, the plate 11 needs to be installed at the air outlet end of the fan. During use, the angle of the first air outlet 25 of the first adjustment component 2 and the second adjustment component 4 can be adjusted according to the airflow distribution position requirements. During adjustment, the adjustment motor 21 drives the threaded rod 23 to rotate. During the rotation of the threaded rod 23, the screw slide 27 is driven to slide. During the movement of the screw slide 27, the push rod 24 is driven to move linearly. During the movement of the push rod 24, the push rod 24 pushes the first air outlet 25 to rotate through the connecting rod 29, so that the first air outlet 25 is at a suitable angle. When the airflow enters the first compartment 12, the second compartment 14 and the third compartment 15, it flows out from the first air outlet 25 and the second air outlet 3, thereby ensuring the uniform distribution of airflow inside the high and low temperature test chamber.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
