Embodiment
Please refer to Fig. 1, Fig. 1 is the generalized section of the heat pipe 1 of first embodiment of the invention.As shown in Figure 1, heat pipe 1 comprises body 10, lid 12, capillary structure 14 and working fluid 16.Body 10 has hollow chamber 100 and opening 102.Body 10 can be made up of the combination (such as, burning metal, common burning porcelain, composite material etc. altogether) of metal (such as, aluminium, copper etc.), pottery, graphite, diamond, other high thermal conductivity materials or other high thermal conductivity materials.In the present embodiment, body 10 is one-body molded, but not as limit.Lid 12 has passage 120.In the present embodiment, passage 120 is L-shaped, but not as limit.Capillary structure 14 is formed in hollow chamber 100, and working fluid 16 to be filled in hollow chamber 100.Capillary structure 14 is in order to promote the heat radiation circulation of working fluid 16.In actual applications, capillary structure 14 can be plough groove type capillary structure, porousness capillary structure, netted capillary structure, powder sintered capillary structure or combined capillary structure, depending on practical application.Above-mentioned combined capillary structure can be made up of at least two kinds of capillary structures in plough groove type capillary structure, porousness capillary structure, netted capillary structure and powder sintered capillary structure.In addition, working fluid 16 can be water or other liquid.
Before opposite heat tube 1 carries out vacuum seal, prior to forming capillary structure 14 in the hollow chamber 100 of body 10, and working fluid 16 can be filled in the hollow chamber 100 of body 10.In addition, also prior to forming capillary structure 14 in the hollow chamber 100 of body 10, then when follow-up opposite heat tube 1 vacuumizes, in the lump working fluid 16 can be filled in the hollow chamber 100 of body 10.
When vacuumizing the hollow chamber 100 of body 10, the gas in the hollow chamber 100 of body 10 can be made to discharge body 10 by the passage 120 of lid 12.Then, make the opening 102 of the complete sealed tube body 10 of lid 12, the hollow chamber 100 of body 10 can be made to present vacuum state.After the opening 102 of the complete sealed tube body 10 of lid 12, namely the passage 120 of lid 12 can be covered by body 10.It should be noted that, before the opening 102 of the complete sealed tube body 10 of lid 12, the gas in the hollow chamber 100 of body 10 all discharges body 10 swimmingly by the passage 120 of lid 12.Whereby, can, when the opening 102 of lid 12 by complete sealed tube body 10, gas slightly be effectively avoided to extract out and to residue in hollow chamber 100.In addition, the present invention can in advance prior to around lid 12 and/or body 10 opening 102 surrounding coating sealing substance (such as, resin, fluid sealant etc.).Lid 12 is pushed the opening 102 of body 10, after being sealed by opening 102, sealing substance can strengthen the vacuum leakproofness between the opening 102 of lid 12 and body 10 further.
Please refer to Fig. 2, Fig. 2 is the generalized section of the heat pipe 1' of second embodiment of the invention.The main difference part of heat pipe 1' and above-mentioned heat pipe 1 is, the lid 12 of heat pipe 1' has external screw thread 122, and the opening 102 of the body 10 of heat pipe 1' has internal thread 104.Therefore, the present embodiment is that the external screw thread 122 of lid 12 is engaged completely with the internal thread 104 of the opening 102 of body 10, and then makes lid 12 with the complete sealed open 102 of the mode of screw-threaded engagement.In like manner, after the opening 102 of the complete sealed tube body 10 of lid 12, namely the passage 120 of lid 12 can be covered by body 10.It should be noted that, the assembly of label identical to those shown in Fig. 1 in Fig. 2, its action principle is roughly the same, does not repeat them here.
Please refer to Fig. 3, Fig. 3 is the generalized section of the heat pipe 1'' of third embodiment of the invention.The main difference part of heat pipe 1'' and above-mentioned heat pipe 1 is, the body 10 of heat pipe 1'' separately comprises lower cover 18.As shown in Figure 3, lower cover 18 can be assembled in below body 10 by welding, close-fitting or other method for metal working.In other words, body 10 can be made from multiple components, and wherein these multiple parts can form body 10 by welding, close-fitting or other intermetallic composite coating forming method.Further, lower cover 18 comprises at least one pyrotoxin, and pyrotoxin comprises semiconductor subassembly.It should be noted that, the assembly of label identical to those shown in Fig. 1 in Fig. 3, its action principle is roughly the same, does not repeat them here.
Please refer to Fig. 4, Fig. 4 is the generalized section of the heat pipe 1''' of fourth embodiment of the invention.The main difference part of heat pipe 1''' and above-mentioned heat pipe 1 is, heat pipe 1''' also comprises multiple radiating fin 20.As shown in Figure 4, radiating fin 20 extends around body 10 in radial mode.In the present embodiment, radiating fin 20 and body 10 are one-body molded, but not as limit.In other embodiments, radiating fin 20 also can be combined by welding, engaging, bonding or other fixed form with body 10.The heat of body 10 can outwards be derived by radiating fin, to promote radiating effect.It should be noted that, the assembly of label identical to those shown in Fig. 1 in Fig. 4, its action principle is roughly the same, does not repeat them here.
Therefore, according to technique scheme, heat pipe of the present invention at least has following advantages and beneficial effect: due to lid having passage, and therefore the present invention can, when vacuumizing the hollow chamber of body, make the gas in hollow chamber discharge body by this passage.Then, make the complete sealed open of lid, hollow chamber can be made to present vacuum state.Compared to prior art, the present invention is the simple and processing ease of structure not only, can effective improving production efficiency.
