It is widely used in environmental reliability testing in fields such as electronics, automobiles, aerospace, and biopharmaceuticals.

[0003] During experiments, it is necessary to ensure the air circulation inside the temperature and humidity chamber. Existing equipment usually uses a fan to drive the air flow, but it cannot achieve uniform air flow inside the temperature and humidity chamber. There is a lack of a baffle plate that can evenly distribute and discharge the air. Utility Model Content

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.

[0020] Example: Reference Figures 1-4 The diagram shows a circulating airflow guide plate for a constant temperature and humidity chamber, comprising a constant temperature and humidity chamber 1, a switch door 2 rotatably connected to the surface of the constant temperature and humidity chamber 1, a ring cylinder 9 fixedly connected to the inner wall of the constant temperature and humidity chamber 1, a heater 6 and a humidifier 7 fixedly installed on the inner wall of the constant temperature and humidity chamber 1, a U-shaped plate 4 fixedly connected to the inner wall of the constant temperature and humidity chamber 1, multiple air inlets 5 opened on the lower surface of the U-shaped plate 4, an exhaust port 15 opened on the surface of the ring cylinder 9, and an air circulation mechanism provided above the constant temperature and humidity chamber 1.

[0021] With the above structure, heating and humidification operations are performed by setting a heater 6 and a humidifier 7. The heater 6 and humidifier 7 are existing devices and will not be described in detail. By setting a U-shaped plate 4, the air circulation is guided. By setting an exhaust hole 15, interference with the air flow is avoided. By setting an air circulation mechanism, the air is ensured to circulate evenly in the constant temperature and humidity chamber 1.

[0022] Preferably, the air circulation mechanism includes a motor 3 fixedly connected to the top of the constant temperature and humidity chamber 1, a drive shaft 11 fixedly connected to the output end of the motor 3, the bottom end of the drive shaft 11 penetrating the surface of the ring cylinder 9 and fixedly connected to a first bevel gear 12, and an L-shaped plate 13 fixedly connected to the inner wall of the ring cylinder 9.

[0023] By setting up motor 3, its output end drives drive shaft 11 to rotate, drive shaft 11 drives first bevel gear 12 to rotate, and by setting up first bevel gear 12, drives second bevel gear 14 to rotate. By setting up L-shaped plate 13, the rotation of fan blade 17 is supported.

[0024] Preferably, a fan blade 17 is rotatably connected to the inner wall of the L-shaped plate 13, and a second bevel gear 14 is fixedly connected to one end of the fan blade 17, with the first bevel gear 12 meshing with the second bevel gear 14.

[0025] By setting the fan blades 17, the air inside the constant temperature and humidity chamber 1 is guided into the U-shaped plate 4 through multiple air inlets 5 and then transported.

[0026] Preferably, an installation plate 10 is installed on the inner wall of the U-shaped plate 4, and multiple breathable meshes 18 are fixedly installed on the inner wall of the installation plate 10, with the width of the multiple breathable meshes 18 increasing sequentially from right to left.

[0027] By setting the mounting plate 10, multiple breathable nets 18 are fixed. The width of the multiple breathable nets 18 increases sequentially from right to left. Since the air in the U-shaped plate 4 comes into contact with the rightmost breathable net 18 first, the advantage of this is to ensure that the amount of air coming out of each breathable net 18 is uniform in the same amount of time.

[0028] Preferably, a limiting magnetic plate 16 is rotatably connected to the surface of the U-shaped plate 4, and the surface of the limiting magnetic plate 16 presses and magnetically attracts the upper surface of the mounting plate 10. A PLC integrated controller 8 is fixedly installed on the surface of the constant temperature and humidity chamber 1.

[0029] By setting a limiting magnetic plate 16, the mounting plate 10 is pressed and magnetically attracted, keeping the mounting plate 10 stable in place and installation, which facilitates subsequent disassembly and dust removal. By setting a PLC integrated controller 8, the drive devices of motor 3, heater 6 and humidifier 7 are integrated and controlled.

[0030] Preferably, an arc-shaped plate 20 is fixedly connected to the upper surface of the breathable mesh 18, and the surface of the arc-shaped plate 20 is provided with a plurality of air outlet holes 19 facing different directions.

[0031] By setting multiple air outlets 19 facing different directions, air can be evenly dispersed in the air after passing through the arc plate 20.

[0032] The working principle of this utility model is as follows: A circulating airflow distribution guide plate in a constant temperature and humidity chamber. When in use, the motor 3 is started, and the output end of the motor 3 drives the drive shaft 11 to rotate. The drive shaft 11 drives the first bevel gear 12 to rotate, and the first bevel gear 12 drives the second bevel gear 14 and the fan blade 17 to rotate. The rotation of the fan blade 17 can draw the air in the constant temperature and humidity chamber 1 through the air inlet 5 into the U-shaped plate 4 for transportation. The air in the U-shaped plate 4 first contacts the rightmost vent mesh 18 and then exhausts in sequence. Since the air in the U-shaped plate 4 contacts the rightmost vent mesh 18 first, the width of the multiple vent meshes 18 increases from right to left. The advantage of this is that it ensures that the amount of air vented in each vent mesh 18 is uniform in the same amount of time. Through multiple air outlets 19 facing different directions, the air can be evenly dispersed in the air after passing through the arc plate 20. During operation, the PLC integrated controller 8 can send electrical signals to control the heater 6 and humidifier 7 to work and carry out heating and humidification operations.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
