Abstract

The utility model discloses a three-dimensional external attachment heat pipe and relates to the field of thermal design of aerospace. The three-dimensional external attachment heat pipe comprises a pipe body and fins. The pipe body is formed through the steps of bending and twisting along the axis, with the twisting angle being 0 to 90 degrees. The pipe body is formed through bending in a plane. The fins are disposed at the two ends of the pipe body. Preferably, the fins at the two ends of the pipe body are fixed to installation surfaces through clamping or gluing. The bending angle is determined according to practical situations on the premise that the pipe body is not contacted with other equipment. Without a fin disposed in the middle section of a conventional heat pipe body, the three-dimensional external attachment heat pipe only keeps the fins at the two ends, thereby being suitable for thermal design of complex instruments and equipment characterized in that installation planes of cold and heat ends form a space angle. The three-dimensional external attachment heat pipe can be bent on site according to a practical installation position, thereby solving the problem of difficult bending and processing of the conventional heat pipe and meeting the requirements for flatness and straightness of the installation planes.

Description

A kind of three-dimensional is pasted heat pipe outward
Technical field
The utility model relates to a kind of three-dimensional and pastes heat pipe outward, belongs to the spacecraft heat design field.
Background technology
It is that the domestic star that on the GEO orbiter, uses first is quick that certain model satellite is installed star sensor (it is quick to be called for short star).In order to reduce noise, to improve image quality, the quick needs of star are operated in (40 ℃~+ 40 ℃) in the lower temperature environment.The quick plate privately that is installed in satellite of star is exposed to outside the star, and near the thermal environment the plate is more abominable privately, proposes requirements at the higher level for the quick thermal design of star.The quick temperature of end of lifetime star is higher, relies on the face coat of the unit heat dissipation problem of can not settling a dispute by the parties concerned themselves own, and needs satellite that the heat radiation approach is provided.Therefore need a kind of three-dimensional to paste heat pipe outward, to solve the heat dissipation problem under instrument and equipment and the radiating surface relative complex situation.Existing tube body of heat pipe is that the full section of straight tube and body has fin, when the installed surface at heat pipe two ends inconvenient installation at grade the time not.
The utility model content
The purpose of the utility model provides a kind of three-dimensional and pastes heat pipe outward, to solve when the installed surface at original heat pipe two ends not at grade the time problem of inconvenient installation during the one-tenth space angle.
For realizing above-mentioned purpose, the technical scheme of the utility model is following:
A kind of three-dimensional is pasted heat pipe outward, comprises body and fin; Said body is along the axis twisting formation, and windup-degree is 0 ~ 90 ° and planar carries out brake forming that wherein said body fin is positioned at the body two ends.
Preferred said body two ends fin is fixed on the installed surface through clip or gluing mode.
Preferred said three-dimensional is pasted heat pipe one end outward and is installed on the plate of cabin, the other end be installed in star quick on.
It is CDRG-NH3-O1-18 * Ф 10 (Ω) that preferred said three-dimensional is pasted the heat pipe cast outward, and heat-transfer capability is 120Wm, and material 1060 is so that the moulding of heat pipe bending pipes.
Wherein, said angle of bend is confirmed according to actual conditions, so that be installed as principle.
Beneficial effect
1, the described three-dimensional of the utility model is pasted heat pipe outward the fin in body stage casing is removed, and it is crooked to carry out scene according to the physical location of installing, and solves the problem that original heat pipe is difficult for installation,
2, the described three-dimensional of the utility model is pasted heat pipe outward and is only kept the two ends fin, can be used for the complex instrument equipment thermal design that hot and cold two ends installed surface becomes space angle, guarantees installed surface flatness and linearity requirement; Satisfy heat-transfer capability simultaneously and thermal resistance requirement from evaporator section fin installed surface to condensation segment fin installed surface.
Description of drawings
Fig. 1 for the described three-dimensional of the utility model paste outward heat pipe at star scheme of installation between the quick and radiant panel;
Wherein, quick, the 2-body of 1-star, 3-cabin plate, 4-fin.
The specific embodiment
Describe the utility model in detail through specific embodiment below.
Embodiment 1
A kind of three-dimensional as shown in Figure 1 is pasted heat pipe outward, comprises body 2 and fin 4;
Wherein said body 2 is planar along the axis twisting formation, and body 2 two ends keep fin 4, and the fin of body 2 remainders removes through machining, and the fin 4 at said body 2 two ends is fixed on the installed surface through clip or gluing mode.
Wherein, said windup-degree is 35 °.
Wherein, said three-dimensional is pasted heat pipe one end outward and is installed on the cabin plate 3, and the other end is installed on the star quick 1.
It is CDRG-NH3-O1-18 * Ф 10 (Ω) that said three-dimensional is pasted the heat pipe cast outward, and heat-transfer capability is 120Wm, and material 1060 is so that the moulding of heat pipe bending pipes.
Wherein, to paste the concrete process of heat pipe outward following for said three-dimensional:
Step 1, body 2 two ends are kept 18mm is wide, the fin 4 of long 100mm, the fin of body 2 remainders is removed through machining by the R cutter;
Step 2, for not contacting with miscellaneous equipment, behind the field sampling body 2 is reversed 35 ° along axis, body 2 is by the panel beating brake forming, to guarantee the relative position of two installed surfaces;
Step 3, body 2 two ends fins 4 are connected with installed surface through clip, thereby satisfy the installation needs.
In sum, more than being merely the preferred embodiment of the utility model, is not the protection domain that is used to limit the utility model.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
