Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and in particular relates to an aging test chamber that can perform air exchange and air circulation. Background Technology

[0002] An aging test chamber is an instrument used to simulate environmental conditions for accelerated aging tests on materials and products. By controlling specific environmental factors such as temperature, humidity or light, the test sample undergoes an aging process equivalent to a long time in the natural environment in a short period of time. The physical and chemical changes (such as color change, strength reduction, cracking, embrittlement, etc.) are observed after a period of time, so as to quickly evaluate its durability, stability and other performance and lifespan in actual use environment.

[0003] Existing aging chambers lack an air duct structure designed for air circulation, and the heating plates cannot generate turbulent airflow, resulting in uneven temperature distribution. This makes it impossible to ensure that all parts of the material receive uniform hot air, which may lead to deviations in test results and fail to accurately reflect the aging condition of the material in actual use environments. Utility Model Content

A sample groove A is provided on the side of the heating plate near the bottom cover plate, and the A inlet of the sample groove A faces the machine head; the side wall of the sample groove A is provided with a side boss A; the end of the side boss A near the A inlet on the heating plate A is provided with a through air inlet channel; the outer wall of the heating plate A near the air inlet channel is provided with an air inlet pipe, and the air inlet pipe is connected to the air inlet channel.

[0006] Furthermore, in some embodiments, a bent-shaped surrounding air duct is provided on the A side protrusion, and the bent-shaped surrounding air duct is arranged around the periphery of the A sample tank; the end of the bent-shaped surrounding air duct near the A inlet is connected to the air inlet channel, and the other end of the bent-shaped surrounding air duct away from the A inlet is provided with an A air outlet, which is connected to the A sample tank.

[0007] Furthermore, in some embodiments, a sample groove B is provided on the side of heating plate B near heating plate A, and the B port of sample groove B faces the machine head; a side boss B is provided on the side wall of sample groove B, and an air inlet is provided at the end of the side boss B near the B port on heating plate B, and the air inlet is connected to the air inlet channel.

[0008] Furthermore, in some embodiments, a B-shaped circumferential air duct is provided on the B-side protrusion, which surrounds the periphery of the B sample groove. The end of the B-shaped circumferential air duct near the B insertion port is connected to the air inlet. The other end of the B-shaped circumferential air duct away from the B insertion port is provided with a B air outlet, which is connected to the B sample groove.

[0009] Furthermore, in some embodiments, the front end of heating plate A, heating plate B, and bottom cover plate is provided with a front cover plate.

[0010] Furthermore, in some embodiments, the air inlet channel runs through the heating plate A, and two air outlets A are opened at the other end of the A-bent circumferential air duct away from the A inlet. The A-type heating plate has a front cover plate at its A-type insertion end, and a sample plate is inserted into the A-type sample groove. The sample plate has several sample placement positions.

[0011] Furthermore, in some embodiments, two sample grooves are provided on the heating plate B, and two air outlets are provided at the other end of the B-shaped circumferential air duct away from the B inlet. The B-type heating plate has a front cover plate at the B-type insertion end, and a sample plate is inserted into the B-type sample groove. The sample plate has several sample placement positions.

[0012] This invention employs a bent, swirling air duct (positive waveform, wave-shaped circulating air duct). The circulating air duct structure generates turbulent airflow within the sample tank, resulting in a more uniform temperature distribution within the aging chamber. This ensures that the sample in the sample tank receives a uniform temperature, thereby improving the reliability of the aging test. Attached Figure Description
