A high and low temperature humidity and heat test chamber

Abstract

The invention provides a high and low temperature thermal-humidity test chamber which comprises a test chamber body module, an electric chamber body module and a refrigerating system, wherein the electric chamber body module is arranged on the back surface of the test chamber body module; and the test chamber body module is connected with the electric chamber body module by a fast connection buckle. An inlet air ducting device and a return air ducting device are arranged on the two sides of a test room; each of the air ducting devices consists of a plurality of adjustable air ducting blocks distributed in an array manner, the air speed and the air quantity of the whole face can be adjusted by adjusting the air speed and the air quantity by every point on a single face, so that the uniformity of the air quantity and the air speed inside the test room can be ensured, and therefore, the uniformity of temperature and humidity inside the test room is ensured, and the accuracy of a testing result is ensured further.

Description

technical field [0001] The invention relates to a test box, in particular to a high and low temperature damp heat test box. Background technique [0002] High and low temperature test chamber: suitable for high temperature and low temperature reliability tests of industrial products. For components and materials of related products such as electronics, automobiles and motorcycles, aerospace, ship weapons, colleges and universities, scientific research units, etc., test their various performance indicators under the condition of high temperature and low temperature (alternating) cycle changes. The high and low temperature test chamber products have the characteristics of simulating the temperature change law in the atmospheric environment. It is mainly aimed at the adaptability test of electrical, electronic products, components and other materials transported and used in high-temperature and low-temperature comprehensive environments. It is used in product design, improvem...

AI Technical Summary

Problems solved by technology

[0004] When testing the effectiveness of automobile roofs and sunroofs, high and low temperature test chambers are required. Most of the existing high and low temperature test chambers have an integrated structure. The normal detection and use can only be carried out after a long period of trial and debugging, which consumes a lot of time and is very inconvenient to use; most of the circulating wind direction in the laboratory area inside the test box is the vertical wind direction. When the product to be tested is placed, the vertical circulating air cannot effectively circulate the air inside the laboratory, so that the uniformity of temperature and humidity inside the laboratory cannot be effectively guaranteed, which affects the accuracy of the test results and has high limitations.
