High-safety heating pad

Abstract

The invention belongs to the field of ring control systems, and particularly relates to a high-safety heating pad. The high-safety heating pad comprises a heating wire, a fiber reinforced layer, a rubber vulcanization layer and a temperature relay. The heating wire is woven in a metal grinding tool cavity. The fiber reinforcing layer is arranged on the periphery of the heating wire. Rubber is integrally vulcanized to form the rubber vulcanization layer, and a space special-shaped structure is formed. The temperature relay is arranged close to one side of the machine body skin. The temperaturerelay is connected with an upper circuit through a wire. By the adoption of the high-safety heating pad, the heat preservation requirement of a product with a large heating area and a space complex structure form can be met, the heating power requirement of each partition in the heating area can be detailed and designed according to requirements, the overall heating uniformity of the product is guaranteed, and the high-safety heating pad has the beneficial effects of being long in service life, high in safety, small in power consumption loss, high in economy and the like.

Description

technical field [0001] The invention belongs to the field of environmental control systems, and in particular relates to a high-safety heating pad. Background technique [0002] With the continuous advancement of aviation manufacturing technology, the single flight time of aircraft is getting longer and longer, and the mission of contemporary aircraft to perform long-duration and trans-oceanic flights is becoming more and more normal. Therefore, during long-distance flights, the need for thermal insulation and anti-icing design of aircraft cabin equipment is becoming increasingly prominent. Preventing icing of pipelines in the cabin has a crucial impact on the safe flight of contemporary aircraft and maintaining normal attendance. [0003] At present, most of the existing thermal insulation and anti-icing products in the cabin are in the form of small area, single temperature control point, and uniform heating on the surface. Such products generally have small heating area, ...

Problems solved by technology

[0003] At present, most of the existing thermal insulation and anti-icing products in the cabin are in the form of small area, single temperature control point, and uniform heating on the surface. Such products generally have small heating area, unadjustable temperature in the heating area, and single temperature control point collection. , low safety factor and other disadvantages, with the development of large-scale and long-distance contemporary aircraft, higher requirements are put forward for the shape, variable heating and high safety of the cabin insulation and anti-icing products, so it is urgent to develop A heating product with large heating area, adjustable temperature in the heating zone, complex curved surface shape and high safety
