Description

Technical Field

[0001] The invention relates to the technical field of test chambers, in particular to layered blowing equipment for component test chambers. Background Art

[0002] The existing test chamber air circulation mode is generally top outlet and bottom return, or bottom outlet and top return. The airflow is relatively concentrated, and it is easy for the air outlet to heat up and down quickly, while the other parts of the test chamber heat up and down slowly, resulting in uneven heating of the test product. It takes a long time for the surface temperature of the test product to reach the deviation range. As the size of photovoltaic modules becomes larger and larger, the inner box height of the test chamber will also become higher and higher, so the problem of uneven heating of the test product will become more serious. Therefore, there is an urgent need for a test chamber that can shorten the time for module temperature balance, thereby shortening the test cycle. Summary of the Invention

[0010] Compared with the prior art, the present invention provides a layered blowing device for a component test chamber, which has the following beneficial effects:

[0011] 1. The layered blowing equipment of the component test chamber blows air simultaneously from top to bottom for the entire interior of the chamber. The air volume is divided into two parts from the air outlet of the wind wheel, and enters the upper air outlet and the middle air outlet respectively. According to the width of the chamber, each layer of air outlet is provided with several air outlets, and by adjusting the direction of the shutters in the air outlet, the blown air can be made more uniform. Because the air outlet is divided into two layers, the circulating motor adopts a variable frequency speed regulation motor. The motor speed can be adjusted according to actual needs to achieve the best blowing effect and quickly cool the sample temperature.

[0012] 2. The component test box is equipped with a layered blowing device. By setting up a middle-layer air outlet mechanism, dust will accumulate on the outer surface of the middle-layer air outlet louver because the middle-layer air outlet louver is used externally for a long time. At this time, when the airflow passes through the middle-layer air outlet louver and enters the position of the test box inside the box, the air volume entering the box will be reduced due to the influence of the accumulated dust. At this time, it is necessary to clean the surface of the middle-layer air outlet louver. However, since the gaps between multiple middle-layer air outlet louvers are small, it is not convenient to clean them quickly. At this time, hold the connecting horizontal plate and drive several long rods to pull the connecting horizontal plate toward the evaporator. The long rods drive several vertical plates to quickly wipe and clean the surface of the middle-layer air outlet louver, and make the dust accumulate and move on the outer wall of the middle-layer air outlet louver, so as to facilitate the rapid cleaning of the dust on the surface of the middle-layer air outlet louver, thereby ensuring the overall air outlet and return air volume in the box.

[0013] 3. The layered blowing equipment of the component test chamber is equipped with a rubber plate and a threaded rod in combination with a sleeve. When the wiper plate and the outer surface of the middle-layer air-outlet louver are moved for cleaning, the sleeve contacts and rotates with the surface of the middle-layer air-outlet louver. While the sleeve rotates, it drives the threaded rod to rotate inside the empty slot. When the threaded rod rotates, since the threaded rod and the rubber plate are threadedly connected, the rubber plate is limited by the internal width of the threaded rod. Therefore, the rubber plate will move downward through the threads outside the threaded rod. At this time, the surface of the middle-layer air-outlet louver is cleaned both horizontally and vertically by the wiper plate and the rubber plate, which further improves the cleaning effect of the surface of the middle-layer air-outlet louver.

[0025] A hollow slot 36 is provided on one side of the wiper plate 29 close to the middle air outlet louver 22, and an inner slot 31 is provided above the inside of the wiper plate 29. A threaded rod 34 is rotatably connected to the upper wall of the inner slot 31, and the lower end of the threaded rod 34 is movable through the inner wall of the inner slot 31 and extends into the interior of the hollow slot 36. A sleeve 32 is fixedly connected to the outside of the threaded rod 34. The sleeve 32 is located inside the inner slot 31, and the outer part of the sleeve 32 is movable through the inner wall of the inner slot 31 and contacts the surface of the middle air outlet louver 22. A rubber plate 33 is threadedly sleeved on the outer thread of the threaded rod 34. The rubber plate 33 is fitted on the surface of the middle air outlet louver 22, and the rubber plate 33 is rectangular and is arranged above the hollow slot 36.

[0026] When using,

[0027] In the first step, when the box 1 is working, the circulation motor 13 drives the wind wheel 14 to rotate and generate suction, sucking the air inside the return air port 17 upward. The sucked-up wind first passes through the evaporator 18 to generate cooling, then passes through the heater 16 to generate heating, and increases the air humidity through the steam pipe 15. The wet steam generated by the humidifying boiler is introduced into the box 1 through the steam pipe 15, stirred at high speed by the wind wheel 14, and then drained through the internal pipe of the box 1. The upper air outlet 11 and the middle air outlet 21 are blown out at the same time to the position where the test box is placed in the box 1, and then return to the return air port, circulating over and over again, thereby achieving the effect of quickly cooling the sample temperature.

[0028] The second step is to set up the middle-layer air outlet mechanism 2. Since the middle-layer air outlet louvers 22 are used externally for a long time, dust will accumulate on the outer surface of the middle-layer air outlet louvers 22. At this time, when the wind flow passes through the middle-layer air outlet louvers 22 and enters the position of the test box inside the box body 1, the air volume entering the box body 1 will be reduced due to the influence of the accumulated dust. At this time, it is necessary to clean the surface of the middle-layer air outlet louvers 22. However, since the gaps between the multiple middle-layer air outlet louvers 22 are small, it is not convenient to clean the dust quickly. At this time, hold the connecting horizontal plate 23 and drive the connecting horizontal plate 23 to pull several long rods 24 toward the direction of the evaporator 18. The long rods 24 drive several vertical plates 28 to quickly wipe and clean the surface of the middle-layer air outlet louvers 22, and make the dust accumulate and move on the outer wall of the middle-layer air outlet louvers 22, so as to facilitate the rapid cleaning of the dust on the surface of the middle-layer air outlet louvers 22, thereby achieving the effect of ensuring the overall air outlet and return air volume in the box body 1.

[0029] The third step is to set the rubber plate 33 and the threaded rod 34 to cooperate with the sleeve 32. When the wiping plate 29 and the outer surface of the middle-layer air-outlet louver 22 are moved to clean, the sleeve 32 contacts the surface of the middle-layer air-outlet louver 22 and rotates. While the sleeve 32 rotates, it drives the threaded rod 34 to rotate inside the empty slot 36. When the threaded rod 34 rotates, since the threaded rod 34 and the rubber plate 33 are threadedly connected, the rubber plate 33 is limited by the internal width of the threaded rod 34. Therefore, the rubber plate 33 will move downward through the threads on the outside of the threaded rod 34. At this time, the surface of the middle-layer air-outlet louver 22 is cleaned both horizontally and vertically by the wiping plate 29 and the rubber plate 33, thereby further improving the cleaning effect of the surface of the middle-layer air-outlet louver 22.
