Embodiment Construction
[0011] refer to figure 1 , an environmental box with variable wind field uniformity in the present invention is mainly composed of a box 1 and a controller 2, and the controller 2 is used to control the environment change of the box 1.
[0012] The controller 2 includes a cooling device 3 , a heating device 4 , a humidifying device 5 and an air handling device 6 , and the air handling device 6 is used to deliver the air treated by the cooling device 3 , heating device 4 , and humidifying device 5 to the cabinet 1 Inside, thereby changing the environmental conditions of the box 1.
[0013] The refrigeration device 3 is preferably a cascade unit using R410 refrigerant at the low-pressure end and R23 refrigerant at the high-pressure end, and its refrigeration temperature can reach -70°C. The heating device 4 preferably adopts electric heating, including front electric heating and post heating, wherein the front electric heating can control the frosting situation, and the post he...

The invention discloses an environmental box with the wind field uniformity variable. The environmental box comprises a box body and a controller used for controlling environmental changes of the box body; the controller comprises a refrigerating device, a heating device, a humidifying device and an air treating device; the box body comprises a shell and an air outlet plate arranged at an opening of the shell, the air outlet plate is formed by splicing a plurality of perforated plates, and the outer side of each perforated plate is provided with a blade baffle capable of shielding through holes formed in the corresponding perforated plate. According to the environmental box with the wind field uniformity variable, ventilating and closing switching of the perforated plates can be controlled by controlling opening and closing of the blade baffles, the wind field uniformity of the whole box can be conveniently and flexibly changed through switching combination of the perforated plates, and then temperature distribution of the whole box can be controlled; comprehensive wind field gradient and temperature gradient inspection can be conducted on a tested product, then the product testing requirements can be better met, and the more comprehensive testing result is achieved.
Description
technical field [0001] The invention relates to a test device for industrial products, in particular to an environmental box with variable wind field uniformity. Background technique [0002] With the development of science and technology, industrial products pay more and more attention to the research of product reliability. Among them, the environmental test chamber is a common and necessary experimental method. However, the wind field control of the environmental test chambers currently on the market is relatively simple. Firstly, it is difficult to guarantee the uniformity requirements of the experimental object for the wind field; secondly, the wind field changes passively with the change of the wind speed; change requirements. Contents of the invention [0003] In view of the above technical problems, the present invention provides an environmental box with variable wind field uniformity, which can provide more flexible test conditions for products, and is easy to...
