| High temperature and high low temperature cycle change are easy to cause material aging, product performance degradation and even failure. This paper designs a equipment of accelerated test in natural environment, which can effectively strengthen the solar radiation heat effect, and uses the natural environment stress to construct the test microenvironment with extreme temperature conditions. The equipment consists of a test chamber, a solar tracking base and a contrallen. Five sides of the test chamber are double-layer insulation structure and the top is made of 2mm thick single-layer aluminum alloy plate. The chamber surface is coated with solar heat absorbing coating ,and the heat absorption rate is more than 90%. Then the black test chamber is installed on the solar tracking base. PLC was used to control the test parameters of the tracking base and the chamber, so that the chamber cover is always vertical to the sunlight. The designed natural acceleration test equipment can not only achieve high-efficiency solar and heat enhancement, but also produce greater temperature difference between day and night and season, and also take into account the influence of other environmental media on the test samples.The developed high-efficiency solar thermal collector natural environment accelerated test equipment is less difficult to process and manufacture, has low energy consumption and high efficiency to cost ratio, and is more suitable for the evaluation of environmental resistance of internal products of outdoor equipment. |
