[0001] The utility model relates to the technical field of test chambers, in particular to a high and low temperature test chamber. Background Art

[0002] A high- and low-temperature test chamber is a device used to simulate extreme temperature environments and is commonly used to test and evaluate product performance and reliability under varying temperature conditions. It can provide both high and low temperature environments and control the rate of temperature change within a certain range. The chamber typically consists of a closed enclosure equipped with a heater and cooler, as well as temperature sensors and a temperature control system.

[0003] In the existing high and low temperature test chambers, the positions of the shelves are mostly fixed, which results in certain requirements on the size of the products when the existing test chambers are used. When facing larger or smaller products, the positions of the shelves cannot be adaptively adjusted.

[0004] In the current technological field, high and low temperature test chambers, as important testing equipment, mostly have fixed internal rack positions, which restricts the versatility and flexibility of the test chambers and makes it difficult to adapt to test samples of various sizes. When faced with large or small products, traditional test chambers cannot dynamically adjust the rack positions, resulting in an inability to effectively accommodate the products, thereby limiting the test scope and application scenarios.
