Technical Field

The utility model relates to the technical field of test boxes, in particular to a stability test box with frequency conversion.

Background Art

A test chamber is a device used for experiments and tests. It usually consists of a sealed space and a control system. The test chamber has many functions and can simulate various specific environments or situations, such as temperature, humidity, pressure, etc. By adjusting the parameters in the control system, we can create a variety of different experimental conditions to conduct targeted experimental research.

Existing test chambers usually use evaporators, condensers, variable frequency compressors and heat exchangers to achieve cooling and heating. However, when conducting experiments, experimental objects are mostly placed directly in the chamber of the test chamber without being fixed. When the test chamber is hit or bumped by external forces, the experimental objects in the test chamber are easy to fall over, and the test chamber is not stable enough to use. For this reason, we propose a stability test chamber with variable frequency.
