Technical Field

The utility model belongs to the technical field of the TV set production technique and specifically relates to a TV set high temperature aging testing device.

Background

China is a country with high television output, not only meets the requirements of the masses of China, but also exports a large number of television products to underdeveloped countries and regions such as Asia-Africa, and even exports television products to developed regions such as Europe and America. In some hot areas, high temperature resistance is an important technical index of televisions. Therefore, most manufacturers have their own high-temperature aging test equipment. However, the existing side-view equipment is simple, namely a simple climate chamber, and is heated by a hot air blower or other heating methods, so that the television is subjected to aging test. It is known that even tropical regions have a variety of climates, for example, tropical rainforest regions are hot and humid and rainy, and desert regions are hot and arid. The simple temperature change cannot truly simulate the real high-temperature environment. In addition, the existing aging test equipment supplies 220V power which is mainstream in China to the television, and as is known, the power supply standard is not adopted in many countries and regions, so that many foreign trade televisions cannot be tested.
