Description

Ventilation device of high-low temperature test chamber Technical Field The utility model relates to the technical field of high-low temperature test boxes, in particular to a ventilation device of a high-low temperature test box. Background A high and low temperature test box is a device for simulating an extreme temperature environment and is commonly used for testing and evaluating the performance and reliability of products under different temperature conditions. It can provide high and low temperature environment and control the rate of change of temperature in a certain range. The test chamber is typically formed by a closed housing with a heater and a refrigerator, and a temperature sensor and a temperature control system. The existing test box lacks measures capable of promoting the air in the box to realize circulating flow, so that the running of the air flow in the box is unsmooth, local temperature difference phenomenon is extremely easy to cause, and due to obvious difference of the heating degrees of products in different areas, the accuracy of test results can be directly interfered, systematic test errors caused by temperature gradients are caused, the validity and reliability of test data are restricted, and the high-standard industrial test requirements are difficult to meet.
