Furthermore, the entire process avoids low-temperature surfaces, eliminating frost formation at its source. Dehumidification and cooling are completely independent; humidity control does not affect temperature, and temperature changes do not affect dehumidification capacity.

Description

Technical Field

[0001] This utility model relates to the field of high and low temperature test chamber technology, specifically a high and low temperature test chamber with dehumidification function. Background Technology

[0002] High and low temperature test chambers are suitable for reliability testing of industrial products under high and low temperature conditions. They are used to test the performance of components and materials in electronic and electrical products, automobiles and motorcycles, aerospace, shipbuilding and weaponry, as well as in universities and research institutions, under cyclic changes in high and low temperatures.

[0003] Currently, when using high and low temperature test chambers, in order to meet the testing needs of various test products, it is necessary to dehumidify the air inside the test chamber. In the existing technology, when drying the air inside the test chamber, due to the large capacity of the test chamber, the dehumidification efficiency decreases as the dehumidification time increases, which increases the dehumidification time and the drying effect is not ideal, thus affecting the use of the test chamber.

[0004] Therefore, this utility model provides a high and low temperature test chamber with dehumidification function to solve the above problems. Utility Model Content

[0005] This invention provides a high and low temperature test chamber with dehumidification function, aiming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a test chamber with a circular cavity inside. A sealing partition is fixedly connected inside the cavity, dividing the cavity into a drying zone and a dehumidification zone. A circulating drying assembly includes an adsorption wheel rotatably connected inside the cavity. An air inlet pipe and a return pipe are fixedly connected to both ends of the drying zone, with an exhaust fan fixedly connected to the bottom of the air inlet pipe. A dehumidification pipe and a hot air pipe are fixedly connected to both ends of the dehumidification zone, with a hot air fan fixedly connected to the top of the hot air pipe. A drive assembly is installed inside the adsorption wheel, which, during dehumidification, is driven by a micro-motor. The system continues to rotate slowly, causing the adsorption rotors to rotate together within the drying and dehumidification zones. An exhaust fan draws moisture from inside the test chamber into the dehumidification zone through the air inlet pipe. The moisture then passes through the adsorption rotors, where the highly hygroscopic honeycomb molecular sieve material absorbs and dries the moisture. The dehumidified gas then flows back into the test chamber through a return pipe. Simultaneously, a hot air blower draws hot air into the drying zone through a hot air pipe. This hot air passes through the adsorption rotors, drying them. Finally, the dried water vapor is discharged through an exhaust pipe. This dual-channel dehumidification and drying combination ensures that the adsorption rotors maintain consistently high adsorption and dehumidification efficiency, while also allowing for continuous, uninterrupted operation.

[0007] As a preferred technical solution of this application, the partition divides the circular cavity into two fan-shaped channels of different sizes: a drying zone and a dehumidification zone. The drying zone and the dehumidification zone are distributed in a 1:3 ratio. The adsorption wheel has uniformly opened honeycomb pores inside. By having the dehumidification zone occupy three-quarters of the circular space, the adsorption wheel can fully contact the moisture, thereby improving the dehumidification efficiency. The inner wall of the honeycomb pores inside the adsorption wheel is coated with a molecular sieve highly hygroscopic material.

[0008] As a preferred technical solution of this application, the driving component includes a rotating shaft, which is fixedly connected to the inside of the adsorption wheel. A micro motor is fixedly connected to the right end of the rotating shaft. The micro motor can drive the rotating shaft to rotate the adsorption wheel, so that when the adsorption wheel rotates slowly, it can alternately pass through the dehumidification zone and the drying zone.

[0009] As a preferred technical solution of this application, the hot air blower is fixedly connected to the top of the test chamber, and the test chamber is rotatably connected to the outside of the chamber. The hot air blower can deliver hot air to the interior of the drying zone, so that the dehumidified adsorption wheel can be dried, ensuring that it always has a good dehumidification effect.

[0010] As a preferred technical solution of this application, a handle is fitted onto the outer surface of the chamber door, and a function panel is provided on the outside of the chamber door. The function panel is electrically connected to the electronic components inside the test chamber and can be used to control the function switching of the test chamber.

[0011] As a preferred technical solution of this application, the bottom of the reflux pipe is threadedly connected to a drying cylinder, the bottom of the test chamber is fixedly connected to a platform, and the top of the platform is fixedly connected to two fixing plates. The platform can support and place the experimental object.

[0012] As a preferred technical solution of this application, the drying cylinder is uniformly fixedly connected with drying plates inside, and each of the two fixed plates is threadedly connected with a screw. The screw can be rotated and moved along the internal threads of the fixed plate, so that the two screws can clamp and limit the object to be tested. The drying plates can further dehumidify the air that flows back into the test chamber. The drying cylinder connected by threads can be easily disassembled to replace the drying plates.

[0013] During the low-temperature test in the test chamber, the circulating drying component continuously draws moisture from inside the chamber into the drying zone, where it comes into contact with the adsorption rotor. This allows the adsorption rotor to adsorb and dry the moisture before it flows back into the chamber. Simultaneously, it continuously dries the adsorption rotor located in the dehumidification zone, ensuring the rotor can continuously perform dehumidification and guaranteeing dehumidification efficiency. Furthermore, the entire process is conducted on a surface free of low temperatures, eliminating the problem of frost formation at its source. Dehumidification and cooling are completely independent; humidity control does not affect temperature, and temperature changes do not affect dehumidification capacity. Attached Figure Description

A circulating drying assembly includes an adsorption wheel 19, which is rotatably connected inside the cavity. An air inlet pipe 8 and a return pipe 10 are fixedly connected to both ends of the drying zone 13, respectively. An exhaust fan 9 is fixedly connected to the bottom of the air inlet pipe 8. An exhaust pipe 15 and a hot air pipe 16 are fixedly connected to both ends of the dehumidification zone 14, respectively. A hot air blower 17 is fixedly connected to the top of the hot air pipe 16. The interior of the adsorption wheel 19... Equipped with a drive component, during the low-temperature test in test chamber 1, the circulating drying component continuously extracts moisture from inside test chamber 1 into the drying zone 13, where it comes into contact with the adsorption wheel 19. This allows the adsorption wheel 19 to adsorb and dry the moisture before it flows back into the test chamber 1. Simultaneously, it continuously dries the adsorption wheel 19 located inside the dehumidification zone 14, ensuring the adsorption wheel 19 can continuously perform dehumidification operations and guaranteeing dehumidification efficiency. Furthermore, the entire process involves no low-temperature surfaces, eliminating the frosting problem at its source. Dehumidification and cooling are completely independent; humidity control does not affect temperature, and temperature changes do not affect dehumidification capacity.

[0018] The partition 12 divides the circular cavity into two fan-shaped channels of different sizes: a drying zone 13 and a dehumidification zone 14. The drying zone 13 and the dehumidification zone 14 are distributed in a 1:3 ratio. The adsorption wheel 19 has uniformly opened honeycomb pores inside. The dehumidification zone 14 occupies three-quarters of the circular space, which allows the adsorption wheel 19 to fully contact the moisture and improve the dehumidification efficiency. The inner wall of the honeycomb pores inside the adsorption wheel 19 is coated with a molecular sieve highly hygroscopic material. The driving component includes a rotating shaft, which is fixedly connected to the inside of the adsorption wheel 19. A micro motor 18 is fixedly connected to the right end of the rotating shaft. The micro motor 18 can drive the rotating shaft to drive the adsorption wheel 19 to rotate. When the adsorption wheel 19 rotates slowly, it can alternately pass through the dehumidification zone 14 and the drying zone 13.

[0019] The hot air blower 17 is fixedly connected to the top of the test chamber 1. The test chamber 1 is rotatably connected to the outside of the chamber door 2. The hot air blower 17 can deliver hot air to the inside of the drying zone 13, so that the dehumidified adsorption wheel 19 can be dried, ensuring that it always has a good dehumidification effect. The outer surface of the chamber door 2 is fitted with a handle 3. The outside of the chamber door 2 is provided with a function panel 4. The function panel 4 is electrically connected to the electronic components inside the test chamber 1 and can be used to control the function switching of the test chamber 1.

[0020] The bottom of the reflux pipe 10 is threadedly connected to a drying cylinder 11. The bottom of the test chamber 1 is fixedly connected to a stage 5. The top of the stage 5 is fixedly connected to two fixing plates 6. The stage 5 can support and place the test objects. Drying plates 20 are evenly fixedly connected inside the drying cylinder 11. The two fixing plates 6 are threadedly connected to screws 7. The screws 7 can be rotated and moved along the internal threads of the fixing plates 6, so that the two screws 7 can clamp and limit the test objects. The drying plates 20 can further dehumidify the air that flows back into the test chamber 1. The drying cylinder 11, which is threadedly connected, can be easily disassembled to replace the drying plates 20.

[0021] When this high and low temperature test chamber with dehumidification function is in use, the micro motor 18 drives the adsorption wheel 19 to rotate slowly and continuously. The adsorption wheel 19 rotates together and is connected to the interior of the drying zone 13 and the dehumidification zone 14. The exhaust fan 9 draws moisture from inside the test chamber 1 into the dehumidification zone 14 through the air inlet pipe 8. The moisture passes through the adsorption wheel 19 and is adsorbed and dried by the highly hygroscopic honeycomb molecular sieve material inside the adsorption wheel 19. Finally, the dehumidified gas flows back into the interior of the test chamber 1 through the return pipe 10. At the same time, the hot air blower 17 draws hot air into the interior of the drying zone 13 through the hot air pipe 16. The hot air passes through the adsorption wheel 19 and dries the dehumidified adsorption wheel 19. Finally, the dried water vapor is discharged through the exhaust pipe 15. The dual-channel dehumidification and drying combination ensures that the adsorption wheel 19 always has good adsorption and dehumidification efficiency and can maintain uninterrupted continuous operation.
