Airgel insulation box applied to high-altitude long-duration unmanned aerial vehicle

Abstract

The invention provides an aerogel thermal insulating box applied to a high-altitude long-time unmanned aerial vehicle. The aerogel thermal insulating box comprises a thermal insulating plate; the thermal insulating plate comprises a supporting framework, an upper skin, a lower skin and an aerogel thermal insulating layer; the supporting framework comprises first supporting framework bodies and second supporting framework bodies, the first supporting framework bodies are sequentially connected in a head-to-end manner to form a supporting frame body, and the second supporting framework bodies are connected between the first supporting framework bodies; the internal space of the supporting frame body is divided into a plurality of grids by the second supporting framework bodies, and the aerogel thermal insulating layer is arranged in the grids; and the upper skin is connected with the upper end face of the supporting frame body, and the lower skin is connected with the lower end face of the supporting frame body. According to the aerogel thermal insulating box, a nanocomposite SiO2 aerogel material which is prepared based on a nanocomposite mechanical enhancing technique and a supercritical drying method is utilized to manufacture the aerogel thermal insulating layer. The aerogel thermal insulating box has the advantages of being light in weight, good in plasticity and low in heat conductivity coefficient.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to an airgel thermal insulation box applied to a high-altitude long-duration unmanned aerial vehicle. Background technique [0002] With the development of unmanned aerial vehicle technology, the requirements for the flying height and airborne time of unmanned aerial vehicle are getting higher and higher. The changing high-altitude environment puts forward higher requirements for the work of stand-alone aircraft such as batteries of unmanned aerial vehicles. [0003] The current thermal control measures are more controlled by thermal control multi-layers or pasted heating sheets. But in a high-altitude environment, air heat conduction is a big problem. The traditional multi-layer has no sealing performance, which is easy to form heat convection, and the multi-layer only has a coating effect, which cannot provide a certain structural support for the single machine. In addition, its sur...
