High and low temperature alternating experiment box

Abstract

The invention discloses a high and low temperature alternating experiment box which comprises a box body, a first partition plate is installed on the upper portion of the interior of the box body, a second partition plate is installed on one side of the top end of the first partition plate, a heating cavity is formed in one side of the second partition plate, an equipment cavity is formed in the other side of the second partition plate, and an electric heating wire is installed on the upper portion of the interior of the heating cavity. An air blower is installed on the inner side of the heating cavity through a fixing base, one end of an air pipe connected with the air outlet end of the air blower penetrates to the position below the first partition plate and is provided with an electromagnetic valve, and a refrigerator body, a high-pressure air pump and an air extractor are installed in the equipment cavity through fixing bases. According to the device, the space where the product is placed above the bearing plate is heated, cooled, pressurized and decompressed, so that high-temperature testing, low-temperature testing, high-pressure testing and low-pressure testing of the product are achieved, a part of severe natural environment is well simulated, experimental detection of the product is achieved, and the device is simple in structure, convenient to operate and high in practicability. And the practicability is good.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a high and low temperature alternating experiment box. Background technique [0002] High and low temperature alternating test chamber is used in electronic and electrical components, automation components, communication components, auto parts, metals, chemical materials, plastics and other industries, defense industry, aerospace, military industry, BGA, PCB base plate, electronic chip IC semiconductor ceramics And the physical changes of polymer materials, testing the material's repeated resistance to high and low temperature and the chemical changes or physical damage of the product's thermal expansion and contraction can confirm the quality of the product. [0003] However, the existing high and low temperature alternating test chambers have fewer functions and cannot adjust the internal pressure, so that it is impossible to simulate the use of the product in di...
