The utility model content
The purpose of this utility model provides a kind of selfexcited oscillating-flow heat pipe with radiating fin.
The utility model is achieved in that a kind of selfexcited oscillating-flow heat pipe with radiating fin, be put together by the double layer of metal plate, double layer of metal plate global formation separately has the type groove, perhaps have only the layer of metal slab integral to form the type groove, described type groove constitutes the pipeline of sealing working medium up for safekeeping of selfexcited oscillating-flow heat pipe at the amalgamation face of double layer of metal plate, have at least the layer of metal plate to extend outwardly in described double layer of metal plate and be bent into fin, described fin closely contacts with the lateral surface of metallic plate.
The utility model can also optionally adopt following attached technical scheme: described each layer metallic plate all is to be formed by flexible flexible metal sheet and the butt joint of inflexible rigid metal plate, the corresponding amalgamation of the flexible metal sheet of double layer of metal plate, the corresponding amalgamation of the rigid metal plate of double layer of metal plate.
The groove depth of the type groove on the described metallic plate is less than the thickness of its place metallic plate.
Compare with existing selfexcited oscillating-flow heat pipe, the utility model is more convenient for producing shape criteria, stay-in-grade selfexcited oscillating-flow heat pipe by unified metric system, be fit to produce in enormous quantities, and the metallic plate and the radiating fin global formation of formation heat pipe, reduce the thermal resistance between fin and the heat pipe, not only made things convenient for the heat dispersion of installing and using but also having improved heat pipe.

The specific embodiment
Referring to Fig. 1 to Fig. 3, the selfexcited oscillating-flow heat pipe of band radiating fin is put together by double layer of metal plate 1,2, double layer of metal plate global formation separately has type groove 3,4, and type groove 3,4 constitutes the pipeline of sealing working medium up for safekeeping of selfexcited oscillating-flow heat pipe at the amalgamation face of double layer of metal plate.The working medium (not shown) forms liquid phase, the alternate plunger of gas phase in the pipeline that is made of type groove 3,4.Working medium can be water, ethanol, R142b, R123 etc.Double layer of metal plate 1,2 can adopt welding, mode amalgamation such as bonding.Wherein layer of metal plate 1 extends outwardly and is bent into corrugated fin 11, and this corrugated fin 11 closely contacts with the lateral surface of metallic plate 1, and closely the mode of contact can be welding or bonding.
Present embodiment can also have following version: (1) has only layer of metal plate 1 global formation that the type groove is arranged, and another layer metallic plate 2 is flat boards that do not have the type groove; Perhaps, (2) extend form Wavelike finned 11 can be towards another layer metallic plate 2 crooked and closely contact with the lateral surface of this another layer metallic plate 2 from metallic plate 1; Perhaps, (3) double layer of metal plate 1,2 all extend outwardly separately and be bent into Wavelike finned, double layer of metal plate 1,2 extend the fin that forms separately with its under the lateral surface of metallic plate closely contact.
Referring to Fig. 4 to Fig. 6, the difference of present embodiment and embodiment 1 is, the groove depth of the type groove 3,4 on the metallic plate 1,2 is less than the thickness of its place metallic plate, make the lateral surface of metallic plate 1,2 can be made into even curface thus, thus make the lateral surface of metallic plate 1,2 be easier to Wavelike finned 11 or the body surface of required heat transfer closely contact.
Version that present embodiment can be taked and embodiment 1 roughly the same repeat no more.
Referring to Fig. 7 to Figure 10, the difference of present embodiment and embodiment 2 is, wherein the layer of metal plate is formed by flexible flexible metal sheet 5 and two inflexible rigid metal plate 6a, 6b butt joints, another layer metallic plate formed by flexible flexible metal sheet 7 and two inflexible rigid metal plate 8a, 8b butt joints, 5, the 7 corresponding amalgamations of two sheets of flexible metallic plate, the corresponding amalgamation of two-layer rigid metal plate 6a, 8a, the corresponding amalgamation of two-layer rigid metal plate 6b, 8b.The position that is put together by two sheets of flexible metallic plate 5,7 can bend, and makes this selfexcited oscillating-flow heat pipe be easier to bending thus, has better Installation Flexibility.Rigid metal plate can adopt heat conduction good material such as copper coin, aluminium sheet, and flexible metal sheet can adopt flexible sheets materials such as copper, aluminium, stainless steel.Rigid metal plate can be docked with bonding way with flexible metal sheet.
Wherein rigid metal plate 6a extends outwardly and is bent into corrugated fin 12, and this Wavelike finned 12 closely contacts with the lateral surface of rigid metal plate 6a
A kind of version as present embodiment, on the basis of Fig. 7, can expand to dock with three or more rigid metal plate by two or more than two flexible metal sheet and form with one deck metallic plate, and in one deck metallic plate, connect a piece flexible metal between per two adjacent rigid metal plate, can make selfexcited oscillating-flow heat pipe be easier to bending so that the flexible position that is put together by the two sheets of flexible metallic plate has many places like this.
Fig. 9 illustrates the structure of two type grooves 3,4 on rigid metal plate 6b, the 8b, and this type groove structure is identical with the type groove structure shown in Figure 6 of embodiment 2.Type groove structure on other two rigid metal plate 6a, the 8a is same as shown in Figure 9.
Figure 10 illustrates the structure of the type groove 9,10 on two blocks of flexible metal sheets 5,7, and this type groove structure is identical with the type groove structure shown in Figure 6 of embodiment 2.
The version that the fin 12 of present embodiment can be taked can repeat no more with reference to the described content of embodiment 1 final stage.
