Description

Technical Field

[0001] The utility model relates to the technical field of air inlet door panels, and specifically relates to an angle adjustable structure of an air inlet door panel. Background Art

[0002] In existing industries such as refrigeration, air conditioning, chemical industry, and pharmaceutical industry, a condensing unit needs to be used to release or recover heat through a cooling or condensing process, so as to achieve specific industrial or environmental control objectives. For example, the condensing unit of a refrigeration device mainly forms the flow of air through the air inlet of the air inlet door panel. However, the existing air inlet door panel is simply a sheet metal folded out with a fixed-angle guide vane, and the air intake volume is fixed, so it cannot meet the different air intake volume requirements of different condensing units. In addition, most of the air inlets are open. When the refrigeration device is not running, dust or mosquitoes in the air will enter the device interior, which will cause dust accumulation inside the device and even breed bacteria in severe cases, affecting the cleanliness of the air blown out by the refrigeration.
