Embodiment Construction

[0037] The following describes a fresh air system for rapid replacement and smoke exhaust of an environmental test chamber according to the present invention with reference to the drawings and specific embodiments:

[0038] A fresh air system for rapid replacement and smoke exhaust of an environmental test chamber, comprising a test chamber body 12, an air intake component and a natural exhaust function component, wherein a part of the air intake component is installed outside the test chamber body 12, and the other part is installed In the test cabin, it passes the replacement gas into the test cabin, decelerates the noise of the gas, and sprays it in the horizontal direction at the bottom of the inner side of the test cabin. The natural exhaust function component is installed in the test chamber to monitor the gas concentration in the test chamber during the test and quickly exhaust it.

[0039] In this embodiment, the air intake assembly includes an intake air flow regulating va...

Abstract

The invention belongs to the technical field of environmental testing, and specifically relates to a fresh air system for rapid replacement and smoke exhaust of an environmental testing chamber, aiming to solve the problem that the prior art cannot meet the requirements of rapid gas replacement and high-precision dynamic pressure control. It is characterized in that it includes a test cabin, an air intake assembly and a natural exhaust function assembly; wherein, a part of the air intake assembly is installed outside the test cabin, and the other part is installed in the test cabin, and the air intake assembly is introduced into the test cabin to replace After the gas is silenced and decelerated, it is ejected horizontally at the bottom of the inner side of the test chamber; the natural exhaust function component is installed in the test chamber to monitor the gas concentration in the test chamber after the test and quickly discharge it. The test chamber adopts a test chamber with air intake at the bottom side and exhaust at the top scattered air outlets, so that the air circulation in the test chamber is sufficient, the gas replacement speed is fast, the dead zone is small, the structure is simple, and it is easy to install and maintain.

Description

Technical field [0001] The invention belongs to the technical field of environmental testing, and specifically relates to a fresh air system for rapid replacement and smoke exhaust of an environmental test chamber. Background technique [0002] In the process of product development, in order to assess the working conditions of the product in a special environment, it is often necessary to build a closed environmental test space to simulate various special environments when the product is working in the closed test space, including high and low temperature, sand dust, salt spray , Rain, low air pressure, low oxygen and other environments. [0003] The test space used to simulate the low-oxygen environment generally adopts the following two working principles. One is to pump the air in the test space to the vacuum state where the product is actually working, and absolutely truly simulate the high-altitude, low-pressure and low-oxygen environment of the product. This has higher requi...
