Description

Technical Field

[0001] This utility model relates to the field of environmental testing equipment, and specifically discloses a heat dissipation device for a xenon lamp aging chamber. Background Technology

[0002] Xenon lamp aging chambers can simulate the damage caused by sunlight, rain, and dew. Using xenon lamps to simulate the effects of sunlight and moisture to simulate rain and dew, the test material is placed in a cycle of alternating light and moisture at a specific temperature. This process can reproduce damage that would occur outdoors over months or even years in just a few days or weeks.

[0003] Chinese patent CN217981193U3 discloses a heat dissipation device for a xenon lamp aging chamber, including a chamber body. The chamber body has a first cavity, a second cavity, a third cavity, and a fourth cavity inside. A rotating mechanism is provided in the second cavity. The rotating mechanism includes a drive assembly, a turntable, a gear, a tray, and a gear ring. The turntable is fixedly installed on the top of the drive assembly. The turntable has multiple through holes, which are equidistantly distributed in a ring around the center of the turntable. The tray is rotatably mounted in the through holes via bearings. A second transmission rod is fixedly installed at the bottom of the tray. The gear is sleeved on the second transmission rod. The gear ring is fixedly installed at the top of the second cavity, and the gear ring meshes with the gear. This invention enables uniform heat dissipation from multiple surfaces of the test sample, thereby improving the accuracy of the test.

[0004] Although the heat dissipation device for a xenon lamp aging chamber disclosed in the aforementioned document can dissipate heat evenly from multiple sides, the heat dissipation mechanism is fixed, making it inconvenient to adjust its position. This results in uneven heat dissipation in the vertical direction and makes it inconvenient to clean the heat dissipation holes. Furthermore, the existing device only uses a fan for heat dissipation, which is not very effective. Therefore, a heat dissipation device for a xenon lamp aging chamber is needed to solve this problem. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-4 A heat dissipation device for a xenon lamp aging chamber includes a chamber body 1, a door 2 on the front end face of the chamber body 1, and multiple equally spaced heat dissipation holes 7 through the left, right and rear end faces of the chamber body 1. An L-shaped plate 3 is fixedly connected inside the chamber body 1.

[0026] The box 1 is equipped with an adjustment mechanism, which includes a lead screw 10 rotatably connected between the top surface of the box 1 and the L-shaped plate 3. The outer wall of the lead screw 10 is threaded with a U-shaped plate 9. The upper end of the box 1 is equipped with a second servo motor 8 whose output end is fixedly connected to the lead screw 10. The outer wall of the U-shaped plate 9 is provided with multiple mounting slots 21 corresponding to the heat dissipation holes 7. The interior of each of the multiple mounting slots 21 is fixedly connected with a brush 22 that abuts against the inner wall of the box 1.

[0027] The inner wall of the U-shaped plate 9 is fixedly connected with multiple support plates 12 corresponding to the heat dissipation holes 7, and the upper surface of each of the multiple support plates 12 is provided with a heat dissipation mechanism.

[0028] In this embodiment: During use, the xenon lamp for the experiment is placed inside the chamber 1, and then an aging test is performed on the xenon lamp to be tested. The output end of the second servo motor 8 drives the lead screw 10 to rotate, so that the lead screw 10 drives the U-shaped plate 9 and the support plate 12 to move up and down, and at the same time drives the heat dissipation mechanism to move up and down, so that the heat dissipation mechanism can dissipate heat evenly in the vertical direction inside the chamber 1, and the heat dissipation effect is better. At the same time, the U-shaped plate 9 drives the brush 22 to move up and down, which facilitates the cleaning of the corresponding heat dissipation holes 7, making the operation more convenient.

[0029] As a technical optimization of this utility model, the heat dissipation mechanism includes a mounting block 13 fixedly connected to the upper surface of the support plate 12. The mounting block 13 has a mounting groove 14 at one end away from the inner wall of the housing 1. Two heat pipes 15 distributed vertically are fixedly connected inside the mounting groove 14. A heat dissipation shell 16 is fixedly connected through the other end of the mounting block 13. A dual-axis motor 17 is installed inside the heat dissipation shell 16 through a bracket. The two output ends of the dual-axis motor 17 are respectively fixedly connected to a first fan blade 18 and a second fan blade 19.

[0030] In this embodiment: the heat pipe 15 absorbs the heat inside the housing 1, and then the two output ends of the dual-axis motor 17 drive the first fan blade 18 and the second fan blade 19 to rotate synchronously, thereby carrying away the heat on the heat pipe 15 (a heat pipe is a component that uses the principle of phase change to achieve efficient heat transfer, which belongs to the prior art), so that the heat is discharged from the housing 1 through the heat dissipation hole 7. The arrangement of the two first fan blades 18, the second fan blade 19 and the heat pipe 15 makes the heat dissipation faster and the heat dissipation effect better.

[0031] As a technical optimization of this utility model, a slide rod 11 that is slidably connected to the U-shaped plate 9 is fixedly connected between the L-shaped plate 3 and the inner top surface of the box 1.

[0032] In this embodiment, the U-shaped plate 9 is prevented from rotating axially by means of the slide rod 11.

[0033] As a technical optimization of this utility model, a turntable 5 is rotatably connected to the upper end face of the L-shaped plate 3, and a first servo motor 4 with its output end fixedly connected to the turntable 5 is installed on the lower end face of the L-shaped plate 3.

[0034] In this embodiment: the first servo motor 4 drives the turntable 5 to rotate, so that the turntable 5 drives the xenon lamp used in the experiment to rotate at a constant speed, making the experimental data more accurate.

[0035] As a technical optimization of this utility model, a sealing gasket 6 is fixedly connected to the rear end face of the door 2, which abuts against the front end face of the box body 1.

[0036] In this embodiment, the sealing performance of the door 2 is increased by using a sealing gasket 6.

[0037] As a technical optimization of this utility model, a protective cover 20 is threadedly connected to one end of the heat dissipation shell 16 near the heat dissipation hole 7.

[0038] In this embodiment, the first fan blade 18 and the second fan blade 19 inside the heat sink 16 are protected by the protective cover 20.

[0039] As a technical optimization of this utility model, the width of the brush 22 is greater than the width of the heat dissipation hole 7.

[0040] In this embodiment, the width of the brush 22 is greater than the width of the heat dissipation hole 7, which makes it easier to clean the heat dissipation hole 7 more thoroughly.

[0041] The working principle and usage process of this utility model are as follows: In use, the xenon lamp for the experiment is first placed on the top of the turntable 5 inside the chamber 1. Then, an aging test is performed on the xenon lamp. The first servo motor 4 drives the turntable 5 to rotate, causing the turntable 5 to rotate the xenon lamp at a uniform speed, making the experimental data more accurate. The output end of the second servo motor 8 drives the lead screw 10 to rotate, causing the lead screw 10 to move the U-shaped plate 9 and the support plate 12 up and down, simultaneously moving the heat dissipation mechanism up and down. The heat pipe 15 absorbs the heat inside the chamber 1, and then the heat is dissipated by the dual-axis motor 17. The two output ends drive the first fan blade 18 and the second fan blade 19 to rotate synchronously, thereby carrying away the heat from the heat pipe 15 (a heat pipe is a component that uses the principle of phase change to achieve efficient heat transfer, which belongs to the prior art). The heat is then discharged from the housing 1 through the heat dissipation holes 7. The arrangement of the first fan blade 18, the second fan blade 19 and the heat pipe 15 makes the heat dissipation faster, thus enabling the heat dissipation mechanism to dissipate heat evenly in the vertical direction inside the housing 1, resulting in better heat dissipation. At the same time, the U-shaped plate 9 drives the brush 22 to move up and down, making it easier to clean the corresponding heat dissipation holes 7, making the operation more convenient.
