Description

Technical Field

[0001] This utility model relates to the field of test chamber technology, specifically a split-type high and low temperature alternating damp heat test chamber. Background Technology

[0002] As is well known, high and low temperature alternating damp heat test chambers are essential testing equipment in fields such as aviation, automobiles, home appliances, and scientific research. They are used to test and determine the parameters and performance of electrical, electronic and other products and materials after temperature environment changes during high temperature, low temperature, alternating damp heat or constant temperature tests. Among them, the split-type high and low temperature alternating damp heat test chamber is more widely used.

[0003] A search revealed a utility model patent published on June 22, 2021, in China, with patent publication number CN213493769U, which discloses a split-type high and low temperature alternating humidity and heat test chamber. The chamber generally includes a main body with a display screen fixedly mounted on its top and control buttons fixedly mounted in the middle. A temperature and humidity connecting pipe is fixedly sleeved on one side of the main body, and a split-type test shell is fixedly sleeved on the other end of the pipe. A temperature and humidity connector is fixedly sleeved on one side inside the split-type test shell. The chamber can be configured as a high-temperature zone, a room-temperature zone, and a low-temperature zone. When it is necessary to change the test parameters such as humidity and temperature, the placement frame is raised and lowered via a drive device to change the zone.

[0004] In the aforementioned existing technical solutions, the temperature zone is adjusted by raising and lowering the placement rack. However, this method has low space utilization. At the same time, due to the heavy weight of the placement rack and the object to be tested, controlling the raising and lowering of the placement rack consumes a lot of energy. Therefore, we propose a split-type high and low temperature alternating damp heat test chamber. Utility Model Content
