Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing by non-limiting embodiment:

[0020]As shown in the accompanying drawings, a vehicle / plate environment test cabin includes an experimental cabin, a fresh air device connected to the experimental cabin, and a filter device 17 connected to the fresh air device. The experimental cabin body adopts an integrally welded stainless steel liner nested structure, and the experimental cabin body includes an internal test cabin 22 and an insulated box 21 arranged outside the test cabin 22 . The test chamber is integrally welded with mirror stainless steel and polished around to make a certain radian. One end of the test cabin 22 is provided with a fresh air guide groove 26, and the top of the test cabin 22 is provided with a static pressure cabin 19, the height of the static pressure cabin is 250mm, and the static pressure cabin 19 includes a plurality of air supply ducts 27 arranged side...

Abstract

The invention discloses a whole automobile / plate environment test cabin for an automobile and a humidity control method for the test cabin. The whole automobile / plate environment test cabin comprises an experiment cabin body, one or more groups of fresh air devices connected with the experiment cabin body and a filtering device connected with the fresh air device, wherein the experiment cabin body comprises a test cabin body and a heat preservation box body arranged outside the test cabin body; a static pressure cabin including a plurality of air supply ducts which are arranged side by side is arranged at the top of the test cabin body; an air supply hole plate with air supply holes is arranged at the lower part of each air supply duct; an air supply fan for supplying air to the test cabin body is arranged in each air supply duct; each group of the fresh air device comprises a fresh air treatment tank and an ultrasonic atomizer; a spraying device is arranged at the upper part in each fresh air treatment tank, and a condenser and a heating pipe are arranged at the lower part in each fresh air treatment tank; the tanks are filled with distilled water; circulating water pumps connected with the spraying devices are arranged outside the fresh air treatment tanks; the humidity is controlled by fresh air humidity control and ultrasonic atomization and humidification modes. The whole automobile / plate environment test cabin can meet the requirements for different fresh air amounts under different experiment conditions and effectively control the humidity.

Description

technical field [0001] The invention relates to an environment test chamber, in particular to an environment test chamber used for automobile whole vehicle test or board material test. The invention also relates to the humidity control method of the vehicle / plate environment test cabin. Background technique [0002] In the prior art, the commonly used environmental testing chambers are relatively small in volume and single in function. At present, there is no environmental testing chamber that can meet both automobile testing standards and plate testing standards. Due to the flow range under the vehicle environmental test chamber is as high as 1000m 3 \H, while the flow rate under the environment test cabin of wood-based panel furniture is 100m 3 \H, the flow accuracy is required to be ±1%. Humidity control is one of the difficulties, and the dehumidification and humidification equipment in the prior art is difficult to accurately control the humidity in the test chamber,...
