Description

Technical Field

[0001] This utility model belongs to the field of test chamber technology, and specifically relates to a rotary xenon lamp aging test chamber. Background Technology

[0002] Current equipment for testing product aging typically uses high-power xenon lamps to simulate sunlight because the light emitted by xenon lamps ages products much faster than sunlight, thus increasing testing speed. Common xenon lamp test chambers generally fix the object to be irradiated inside a tray before irradiating its surface with a xenon lamp. However, because the object is stationary inside the tray, its sides are not effectively irradiated, reducing the quality of the aging test. Furthermore, although a circulating fan is designed to create airflow within the test chamber, the airflow is not evenly distributed, affecting the temperature uniformity inside the chamber. Utility Model Content

[0003] The purpose of this invention is to provide a rotary xenon lamp aging test chamber. By designing a drive motor to slowly rotate the product under test on the disc, the irradiation uniformity of the product under test can be improved. At the same time, through the design of the return air grid and the air inlet grid on the air duct cavity, the circulating hot airflow can be evenly distributed, thereby improving the temperature uniformity inside the test chamber.

[0004] To solve the above-mentioned technical problems, this utility model provides a rotary xenon lamp aging test chamber, comprising:

[0005] The test chamber is located inside the test box, and a disc is rotatably mounted on the bottom of the test chamber. The bottom shaft end of the disc extends to the bottom of the test chamber and is connected to the output end of the drive motor.

[0006] Xenon lamps are arranged in multiple groups at intervals on the top of the test chamber, and the xenon lamps are cooled by air.

[0007] The air duct cavity is located on the rear side of the test chamber, and multiple centrifugal fans are installed at intervals on the top left and right of the air duct cavity. The air duct cavity also includes return air grids and inlet air grids, which are arranged vertically.

[0008] Preferably, the disc also includes several locking holes for fixing a fixture on which the product to be tested is placed.

[0009] Preferably, the chamber also includes a heat sink, which is installed on the top of the test chamber, and the irradiation surface of the xenon lamp is exposed and installed on the bottom of the heat sink. One end of the heat sink is vertically connected to the outside of the top of the test chamber through an air inlet pipe, and the other end is horizontally connected to the outside of the side wall of the test chamber through an air outlet pipe. An axial fan is installed at the air inlet pipe.

[0010] Preferably, it also includes copper heat dissipation fins, which are linearly installed inside the heat dissipation box.

[0011] Preferably, the return air grid includes a first distribution grid and a second distribution grid arranged at intervals; both the first distribution grid and the second distribution grid have linearly formed I-shaped grooves.

[0012] Preferably, the I-shaped slot on the first distribution grid can be switched to the I-shaped slot on the second distribution grid by rotating the pointer clockwise or counterclockwise by 90°.

[0013] Preferably, it also includes a temperature sensing probe for monitoring the temperature inside the test chamber.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This invention improves the irradiation uniformity of the test product by using a drive motor to slowly rotate the product on the disc. Simultaneously, the design of the return air grid and inlet air grid in the air duct cavity allows for uniform distribution of the circulating hot airflow, improving the temperature uniformity inside the test chamber. Furthermore, the design of the heat sink and heat dissipation fins enables air cooling of the xenon lamp, extending its lifespan. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0024] like Figures 1-6 As shown, this utility model embodiment provides a rotary xenon lamp aging test chamber, which has a door and includes:

[0025] Test chamber 2 is located inside test chamber 1, and a disc 3 is rotatably mounted on the bottom of test chamber 2. The bottom shaft end of disc 3 extends to the bottom of test chamber 2 and is connected to the output end of drive motor 4. Drive motor 4 drives disc 3 to rotate slowly.

[0026] Xenon lamps 5 are arranged in multiple sets at intervals on the top of the test chamber 2, and are cooled by air cooling. By arranging multiple sets of xenon lamps 5, the irradiation area of ​​xenon lamps 5 can be increased, and air cooling can be used to cool and dissipate heat.

[0027] The air duct cavity 6 is located on the rear side of the test cavity 2, and multiple centrifugal fans 7 are installed at intervals on the top left and right of the air duct cavity 6. The air duct cavity 6 also includes a return air grid 8 and an inlet air grid 9, which are arranged vertically. When the centrifugal fans 7 work, the hot air flow in the test cavity 2 after being heated by the xenon lamp 5 can be driven to flow into the air duct cavity 6 through the inlet air grid 9. After the hot air flow is distributed by the return air grid 8, it is circulated back into the test cavity 2, thereby improving the temperature uniformity in the test cavity 2 and improving the aging test effect.

[0028] The disc 3 also includes several locking holes for fixing the fixture on which the product to be tested is placed.

[0029] The test chamber also includes a heat sink 51, which is installed on the top of the test chamber 2. The irradiation surface of the xenon lamp 5 is exposed on the bottom of the heat sink 51. One end of the heat sink 51 is vertically connected to the outside of the top of the test chamber 1 through an air inlet pipe 52, and the other end is horizontally connected to the outside of the side wall of the test chamber 1 through an air outlet pipe 53. An axial flow fan is installed at the air inlet pipe 52. Through the operation of the axial flow fan, the external airflow is driven to flow through the air inlet pipe 52 into the heat sink 51, carrying away heat and dissipating it through the air outlet pipe 53, thus achieving the purpose of air cooling.

[0030] It also includes copper heat dissipation fins, which are linearly installed inside the heat dissipation box 51. The copper heat dissipation fins can accelerate heat conduction and heat dissipation area.

[0031] The return air grid 8 includes a first distribution grid 81 and a second distribution grid 82 arranged at intervals. Both the first distribution grid 81 and the second distribution grid 82 are linearly provided with I-shaped grooves 83. The hot air in the air duct cavity 6 can be uniformly distributed in a secondary manner through the I-shaped grooves 83.

[0032] The I-shaped slot 83 on the first distribution grid 81 can be switched to the I-shaped slot 83 on the second distribution grid 82 by rotating the pointer 90° clockwise or counterclockwise, which further improves the uniformity of secondary distribution of hot airflow.

[0033] It also includes a temperature sensor probe for monitoring the temperature inside the test chamber 2, and controlling and adjusting the irradiation power of the xenon lamp 5 by sensing temperature changes.

[0034] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
