The technical scheme has the beneficial effects that the lightweight low-thermal resistance radiator is simple in structure, technically reasonable, convenient to operate, light in weight and strong in strength, and the thermal resistance, the weight and the mechanical properties are further improved.
Description
Technical field
The present invention relates to spacecraft Evolution of Thermal Control Technique field, refer to especially a kind of lightweight low thermal resistance exciter.
Background technology
Along with the development of space technology, high rail and inclined plane satellite are more and more.The satellite heat delivery surface that runs on high rail or inclined plane is shone often in turn.In order to save the energy valuable on star, and improve the radiating efficiency of heat delivery surface, often will be subject in turn to carry out the isothermal processing according to heat delivery surface.Now, often the outer mode of pasting heat pipe of employing is carried out the isothermal processing to heat delivery surface, but outer subsides heat pipe can't meet large heat, transmits at a distance.Along with the development of high-power spacecraft, the isothermal processing mode of outer subsides heat pipe can't meet the thermal control demand of spacecraft.
In addition, in the past in model because the platform hear rate is little, the body heat delivery surface can meet the thermal control requirement of model.But, along with the sustainable growth of requirement of communication, commercial satellite, particularly military satellite, and the development tendency of satellite miniaturization, maximization and common platform application, on star, the heating power of device constantly increases; It is increasing that the capacity weight of common platform rolls up the hear rate energy density that also makes whole star, and its heat removal issue is also more and more serious.Only rely on the body heat delivery surface of satellite can't meet the thermal control requirement of model.For problems such as solution satellite body heat delivery surface deficiencies, external satellite has had the experience of application expandable type exciter.As HS702 platform, Laura SS/L1300 platform, the Laura SS/L1300E satellite platform of the U.S., the large-scale communication satellite platform Alphabus in Europe etc.
No matter be as cabin plate or expandable type exciter, especially, when radiator area is larger, its radiating efficiency to exciter, structural strength and weight indicator all have higher requirements.Technical scheme provided by the present invention is intended to meet the growth requirement of exciter technology, and the process implementing difficulty is less, possesses the engineering using value.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of lightweight low thermal resistance exciter, guarantee under the prerequisite of exciter mechanical property, reduce in exciter the thermal contact resistance between working medium pipeline and exciter substrate with the heat loss through radiation efficiency of raising exciter, alleviate the weight of exciter simultaneously, and reduce the process implementing difficulty of exciter.
For solving the problems of the technologies described above, embodiments of the invention provide a kind of lightweight low thermal resistance exciter, comprise boss panel, aluminium honeycomb, coupling agent, working medium pipeline and lead-covering, described aluminium honeycomb is between boss panel and lead-covering, described working medium pipeline is pre-buried in the aluminium honeycomb and near the boss panel, and described working medium pipeline is connected to the boss panel by coupling agent.
As preferably, the lower surface of described working medium pipeline welding and boss panel.
As preferably, described working medium pipeline is by structural adhesion, silaatic, heat-conducting glue a kind of lower surface gluedd joint with the boss panel wherein.
As preferably, described aluminium honeycomb length is 5mm, and thickness is 0.03mm, and density is 35kg/m
3.
As preferably, described working medium pipeline is a kind of in stainless steel pipe and aluminium alloy pipe.
The beneficial effect of technique scheme of the present invention is as follows: simple in structure, technology is reasonable, easy to operate, and equipment completes lightweight and makes, and has high-strength characteristic, in thermal resistance, weight, mechanical property, further raising is all arranged.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of lightweight low thermal resistance exciter embodiment of the present invention.
［ main element nomenclature ］ be the boss panel 1., 2. aluminium honeycomb, 3. coupling agent, 4. working medium pipeline, 5. lead-covering.
The specific embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The present invention is directed to existing deficiency a kind of lightweight low thermal resistance exciter is provided, as shown in Figure 1, comprise boss panel 1, aluminium honeycomb 2, coupling agent 3, working medium pipeline 4 and lead-covering 5, described aluminium honeycomb 2 is between boss panel 1 and lead-covering 5, described working medium pipeline 4 is embedded in advance in aluminium honeycomb 2 and, near boss panel 1, described working medium pipeline 4 is connected to boss panel 1 by coupling agent 3.
The lower surface of described working medium pipeline 4 welding and boss panel 1.
Described working medium pipeline 4 is by structural adhesion, silaatic, heat-conducting glue a kind of lower surface gluedd joint with boss panel 1 wherein.
Described aluminium honeycomb 2 length are 5mm, and thickness is 0.03mm, and density is 35kg/m
3.
Described working medium pipeline 4 is a kind of in stainless steel pipe and aluminium alloy pipe.
Be below to compare with the material of existing two kinds of technical schemes:
Table 1
Be below to compare with the data of existing two kinds of technical schemes:
Table 2
Three kinds of scheme mechanical properties, thermal property, resource requirement and technique exploitativeness comparative results are as shown in table 2.Aspect mechanical property, the present invention and scheme one are all honeycomb plate structure, high-strength characteristic with bending block, can be used as spacecraft module plate or expansion equation exciter uses, scheme two mechanical properties are poor, when radiator area is larger, can only directly be routed to spacecraft structure plate surface and uses.Aspect thermal property, thermal resistance of the present invention and scheme one approach, and scheme two exciter pipelines and aluminium sheet area of contact are less, cause thermal contact resistance larger.Aspect resource requirement, surface density minimum of the present invention, scheme three surface density maximums.Aspect the technique exploitativeness, boss panel of the present invention needs accurate machinework.The loop circuit heat pipe evaporator be connected with exciter or mechanical pump due to the machinework precision, be generally stainless steel with the reason such as working medium compatibility, so in scheme one, a technique difficult problem of welding between the dissimilar metal thin wall pipelines is faced on the working medium tube road surface of exciter; Scheme two process implementings are simple, but compressed the process implementing mode of working medium pipeline by press strip, because the spacing of rivet compresses the thrust difference that causes the working medium pipeline, make the working medium pipeline phenomenon of coming unstuck in part may occur.Relatively comprehensive, the present invention program has larger advantage in thermal resistance, weight, mechanical property or process implementing difficulty, meets the high demand of aeronautical product to properties of product.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite that does not break away from principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
