The temperature index of the temperature and humidity test chamber has temperature range, temperature uniformity and temperature fluctuation. When the temperature is adjusted during the test, there are many factors that affect the equilibrium state of the temperature uniformity. In order to achieve the minimum error of the data, Xiaobian is here. The article summarizes several common influencing factors for users: 1) Thermal load factor → If the test sample in the test chamber is placed enough to affect the internal thermal convection, it will inevitably affect the uniformity of the internal temperature to a certain extent. For example, if the LED lighting product is placed, the product itself exists. In the case of radiant heat, it becomes a heat load, and then there is a great influence on temperature uniformity; 2) Heat transfer → Since the heat transfer coefficient of the front and rear of the box wall of the studio is different, the design of small details such as threading holes, detection holes and test holes may cause local heat dissipation and heat transfer. The temperature of the equipment box is uneven, and the convective heat transfer of the box wall is also uneven, which affects the temperature uniformity; 3) Thermal radiation → design problems lead to the difficulty in achieving a uniform symmetrical structure in the design of the internal structure and space of the test chamber. The asymmetric structure of the temperature and humidity test chamber will inevitably lead to deviations in the internal temperature uniformity. The main one is reflected in the sheet metal design and its processing, such as the design of the air duct, the placement of the heating pipe, the size of the fan power, etc.; Sketching Chair Set,Sketching Chair,Sketching Chair With Tablet,Training Chair With Tablet AU-PINY FURNITURE CO., LTD , https://www.au-piny.com
