Description

Heating system and its manufacturing method {Heating system and the method thereof}

The present invention relates to a heating system, and more specifically, to a heating system with increased space efficiency.

Since the environment in which the satellite operates is a harsh environment such as deep space with a temperature of about 270 degrees or solar radiation, equipment for insulation, heat dissipation, and heating is installed in order for the main satellite equipment to operate normally.

In the conventional technology, heat was controlled by attaching a heater to each individual device, installing box-shaped insulation, and wrapping spiral heaters and insulation around the piping. However, small satellites with very close distances between devices or high-orbit satellites that require a large number of devices For example, in the case of lunar orbiters or planetary probes, there was a problem that heat control was impossible because assembly space was not secured during thermal design.

In particular, in the case of high-orbit satellites, the push-type fuel supply equipped with only a fuel tank, which has been used in conventional low-Earth orbit satellites, does not generate a constant thrust and cannot travel to the moon corresponding to high orbit. Since a large number of mechanical devices such as propulsion system pressure control devices and pressurized gas tanks have been installed, high-orbit satellites inevitably reduce the distance between devices and are equipped with electronic devices such as sensors and heaters to maintain the temperature of the devices. As physical space became scarce, it became more difficult to solve the space utilization problem described above.

Therefore, the design of insulation, heat dissipation, and heating systems that can be applied to high-orbit satellites or small satellites has emerged as a major task.

At this time, the heating unit 200 may not directly contact the surface of the heated unit 300 and directly heat the heated unit 300, but may transfer heat indirectly through the air in the insulated space. there is. That is, it is preferable that the surfaces of the heating unit 200 and the heated unit 300 are spaced apart from each other by a predetermined distance. Accordingly, the heating unit 200 can easily transfer heat to the heating unit 300 even if there is no space for the heating unit 200 to be mounted on the heating unit 300.

As an example of the present invention, as shown in FIG. 2, the heated portion 300 is a mechanical device mounted on a satellite or small satellite flying in an orbit of low Earth orbit or higher, and the insulating portion 100 is the heated portion 300. It is a thin-film insulating material that surrounds the entire outer surface of the , and the heating unit 200 may be a thin-film radiant heater mounted inside the insulating material.

In the case of satellites flying in low-Earth orbit or higher, such as lunar exploration satellites, a number of mechanical devices such as fuel tanks as well as propulsion system pressure control devices and pressurized gas tanks have been mounted to generate constant thrust, and inevitably, equipment As the distance between devices is reduced, there is not enough physical space to mount electronic equipment such as sensors or heaters that maintain the temperature of the equipment, so applying the heating system 1000 of the present invention can provide a significant effect.

Hereinafter, the heating unit 200 will be described in more detail with reference to FIG. 3.

It is preferable that the heating areas 210 of the heating surface are driven independently from each other to heat the portion to be heated 300. Accordingly, the heated portion 300 may be heated as a whole or locally. Due to this characteristic, the heated portion 300 can be heated locally when precise heat control is required in the heated portion 300 depending on the components included in the heated portion 300.

The heating unit 200 may have a metal tube and a heating line printed linearly on a thin ceramic film. According to the heating area 210 of the heating unit 200, the metal tube and the heating wire are separated from each other, and the heated area is It can be arranged according to the shape of (300). That is, the metal tube and heating line are printed as one line in the first heating area 210, and in the second heating area 210, they are printed as another line that is not connected to the first heating area 210, so that each heating Area 210 may be configured.

At this time, the temperature reference value for operating the heating unit 200 may be different for each heating area 210. For example, in the case of the heating area 210 in which many components vulnerable to cold are mounted, the standard temperature may be higher than that of another heating area 210. That is, even if the same temperature value is received from the heat detection sensor attached to each heating area 210, the heating area 210 where components vulnerable to cold are located may be operated more sensitively.

In more detail, the heating unit 200 may have a metal tube and heating wires printed linearly on a thin ceramic film, and the metal tube and heating wires may be arranged according to the shape of the heating target unit 300. For example, metal pipes and heating wires may be placed at a higher density in locations where major components of the heated portion 300 or components vulnerable to cold are placed, or metal pipes and heating wires capable of generating higher temperature heat may be placed. In addition, in empty spaces or locations where parts that are not vulnerable to cold are placed, metal tubes and heating wires may not be placed or may be placed at a low density.
