[0002] Aviation boxes are containers used to load and transport goods. They are usually made of metal or plastic and have waterproof, shockproof and collision-proof capabilities. In air transportation, they play an important role in protecting and safely transporting goods. The increasingly frequent cross-border trade has brought the use and development of aviation boxes into a golden stage, especially in the fields of stage lighting equipment, medical instruments and equipment, audio-visual system multimedia, optoelectronics industry, military transportation packaging, and military equipment transportation. High-tech equipment such as transportation is widely used; in the prior art, some items have certain requirements for storage temperature, so some aviation boxes also have a constant temperature function. By laying heat-insulating materials inside the aviation box, the heat transfer is blocked and the temperature inside the aviation box is kept constant, but it is only suitable for short-term storage. In order to extend the constant temperature time of the aviation box, some aviation boxes will set a temperature regulating component inside the aviation box to automatically adjust the temperature inside the aviation box to keep the temperature inside the aviation box constant. However, because the aviation box needs to store items inside, the temperature regulating component is mostly installed on the side wall of the aviation box, resulting in insufficient temperature regulation inside the aviation box, and the temperature inside the aviation box is prone to unevenness.
