Thermal control method for aerospace equipment

Abstract

One embodiment of the invention discloses a thermal control method for aerospace equipment. The thermal control method comprises the steps that S100, arranging a first filler at the position, corresponding to the to-be-installed aerospace equipment, of a cabin plate of a spacecraft; S102, applying a pressure, so that air between the first filler and the deck is exhausted; S104, arranging a film type electric heater on the first filler; S106, arranging a second filler on the film type electric heater; S108, applying a pressure to discharge air among the first filler, the second filler and the film type electric heater; and S110, arranging the aerospace equipment to be installed on the second filler, and exhasuting air between the second filler and the equipment through pressing. The method has the following advantages that the implementation process of the electric heater and the installation process of equipment are synchronously carried out, a traditional gluing mode is not used, and the glue curing time is saved; the whole implementation process is extremely high in operability, and air on the contact interface of the heater and the filler can be effectively exhausted.

Description

technical field [0001] The invention relates to the field of implementing thermal control measures for aerospace equipment. More specifically, it relates to a thermal control method for aerospace equipment. Background technique [0002] At present, aerospace technology is an important means of quickly acquiring and transmitting information, and has a wide range of application requirements in military and commercial fields. The harsh operating environment puts forward high requirements on the adaptability of aircraft, aerospace equipment and loads to the space thermal environment. . In order to ensure that the temperature level and stability of the aircraft and its key equipment meet the normal working requirements, the design of the thermal control system becomes the key to the overall system design and development. Thermal control system design includes active thermal control design and passive thermal control design. Passive thermal control measures suppress or strengthe...

Problems solved by technology

[0009] When heaters need to be implemented on multiple surfaces of the object to be controlled, multiple surfaces need to be pasted and cured by heaters in sequence, and the serial implementation process takes a long time;

[0010] From the implementation results, based on the currently commonly used heater paste process, the implementation effect is not stable, and the probability of large bubbles or many small bubbles appearing when the silicone rubber is cured is relatively high, which hinders the heater from connecting with the surface of the controlled object. In severe cases, the resistance element at the position of the bubble will be blown, thus making the active thermal control circuit invalid
