Description
- 1. Field of the Invention
- The present invention relates generally to a thermal module assembling structure, and more particularly to a thermal module assembling structure in which the heat dissipation board and the heat pipe are deformed to restrict each other.
- 2. Description of the Related Art
- A prior art discloses a heat dissipation substrate structure. A heat pipe is embedded in the heat dissipation substrate and then riveted with the heat dissipation substrate by means of mechanical riveting. After riveted, the rivet is closed up to keep the surface of the heat dissipation substrate a plane face. The heat dissipation substrate includes a receiving channel formed in the heat dissipation substrate structure for receiving the heat pipe. Two ribs are formed on two sides of the receiving channel in immediate adjacency to each other. The two ribs are higher than the surface of the heat dissipation substrate structure. Two material escape receptacles are formed in the heat dissipation substrate structure in immediate adjacency to outer sides of the ribs respectively. Accordingly, when the heat pipe is embedded into the heat dissipation substrate and riveted with the heat dissipation substrate by means of mechanical riveting, the ribs hold the heat pipe and the material escape receptacles receive the residual metal produced in the mechanical riveting and close-up process of the ribs. Therefore, the surface of the heat dissipation substrate structure can keep plane.
- The above heat dissipation substrate structure is able to prevent the heat pipe from being extracted out of the substrate. However, in practice, the ribs and the receiving channel simply embrace the circumferential surface of the heat pipe. Therefore, the heat pipe is still likely to be extracted out of the receiving channel in the lengthwise direction of the receiving channel, (that is, the axial direction of the heat pipe).
- It is therefore a primary object of the present invention to provide a thermal module assembling structure. In the thermal module assembling structure, the mating faces of the two ribs on two sides of the receiving channel of the heat dissipation board and the heat pipe in the receiving channel are locally deformed to form at least one deformed connection section for tightly fitting and connecting the heat pipe with the ribs.
- It is a further object of the present invention to provide the above thermal module assembling structure in which the deformed connection section between the mating faces of the ribs and the heat pipe is substantially normal to the axis of the heat pipe so as to apply an interference force to the heat pipe to prevent the heat pipe from being extracted out of the receiving channel along the length thereof.
- To achieve the above and other objects, the thermal module assembling structure of the present invention includes a heat dissipation board having a receiving channel formed in the heat dissipation board for a heat pipe to fit through the receiving channel. Two sides of upper side of the receiving channel are respectively formed with ribs, which horizontally protrude and extend toward the middle of the receiving channel. Each rib has an upper surface and a lower surface. The lower surface faces a surface of the heat pipe. At least one deformed recess is formed on the upper surface of each of the ribs, whereby the lower surfaces of the ribs and the surface of the heat pipe are deformed to form at least one deformed connection section between the lower surfaces of the ribs and the surface of the heat pipe.
- In the above thermal module assembling structure, the deformed connection section is substantially normal to an axis of the heat pipe.
- In the above thermal module assembling structure, the deformed connection section includes a deformed raised portion and a deformed recessed portion. The deformed raised portion is formed on the lower surface of the rib. The deformed recessed portion is formed on the surface of the heat pipe.
- In the above thermal module assembling structure, the deformed raised portion and the deformed recessed portion are tightly fitted and engaged with each other to restrict each other.
- By means of the restriction of the deformed connection section, the heat pipe is truly prevented from being extracted out of the receiving channel along the length of the receiving channel.
- The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein:

FIGS. 1 , 2A, 2B, 2C and 2D.FIG. 1 is a perspective exploded view of the heat dissipation board and heat pipe of the present invention.FIG. 2A is a perspective assembled view of the heat dissipation board and heat pipe of the present invention.FIG. 2B is a view showing that the ribs are formed with deformed recesses.FIG. 2C is a sectional view taken alongline 2C-2C ofFIG. 2B .FIG. 2D is an enlarged view of circled area ofFIG. 2C . - As shown in
FIGS. 1 and 2A . The thermal module assembling structure of the present invention includes aheat dissipation board 10 and aheat pipe 20. Theheat dissipation board 10 has a receivingchannel 11 formed in theheat dissipation board 10. Theheat pipe 20 is fitted through the receivingchannel 11 and connected with theheat dissipation board 10 by means of press fit. Theheat dissipation board 10 is made of metal or alloy material with good thermal conductivity, such as copper, aluminum, gold or silver. Theheat pipe 20 can be entirely fitted through the receivingchannel 11. Alternatively, only one end of theheat pipe 20 is fitted through the receiving channel 11 (as shown inFIG. 2A ). According to the cross section, theheat pipe 20 can be flat-plate heat pipe, circular heat pipe or semicircular heat pipe. According to the configuration, theheat pipe 20 can be a straight heat pipe or a curved heat pipe. - Basically, the
heat pipe 20 is a closed chamber containing therein a working fluid. By means of continuous liquid-vapor phase change circulation of the working fluid in the chamber and the convection of the going vapor and coming liquid between the heat absorption end and the heat dissipation end, the heat can be quickly spread through the surface of the chamber to transfer the heat. The operation principle of the heat pipe is that the liquid-phase working fluid absorbs heat at the heat absorption end and evaporates into vapor-phase working fluid. In the instant of evaporation, a local high pressure is created in the chamber to urge the vapor-phase working fluid to flow to the heat dissipation end at high speed. After the vapor-phase working fluid condenses into liquid-phase working fluid at the heat dissipation end, due to the gravity/capillary attraction/centrifugal force of the capillary structure in the chamber, the liquid-phase working fluid flows back to the heat absorption end to recycle the operation. Therefore, in operation of the heat pipe, the airflow is driven by the air pressure difference, while the liquid flow is driven by a suitable backflow drive force adopted or designed according to the operation state in use. The heat pipe is formed as a closed chamber by means of the pipe body structure. The pipe body not only should be able to structurally bear the difference between internal pressure and external pressure, but also serves as a medium material for conducting heat into and out of the chamber. Currently, the material of the pipe bodies of most of the small-size heat pipes applied in the electronic heat dissipation field is copper. In consideration of weight or cost, some other heat pipes are made of copper pipe or titanium pipe. - Two sides of upper side of the receiving
channel 11 are respectively formed withribs 12. Theribs 12 horizontally protrude and extend along asurface 13 of theheat dissipation board 10 toward the middle of the receivingchannel 11. Eachrib 12 has anupper surface 121 and alower surface 122. Theupper surface 121 is positioned on the same level as thesurface 13 of theheat dissipation board 10. Thelower surface 122 faces asurface 21 of theheat pipe 20 fitted through the receivingchannel 11. As shown inFIGS. 2B , 2C and 2D, at least onedeformed recess 123 is formed on theupper surface 121 of each of theribs 12 by means of mechanical processing (pressing, rolling or riveting). In this case, thelower surface 122 of therib 12 and the surface 21 (not shown) of theheat pipe 20 in contact with thelower surface 122 are deformed. Accordingly, at least onedeformed connection section 30 is correspondingly formed between thelower surface 122 of therib 12 and thesurface 21 of theheat pipe 20. In this embodiment, there are multipledeformed recesses 123 arranged along the length of therib 12 at intervals. Thedeformed recesses 123 make thelower surfaces 122 of theribs 12 and thesurface 21 of theheat pipe 20 deformed to correspondingly form multipledeformed connection sections 30 between thelower surfaces 122 of theribs 12 and thesurface 21 of theheat pipe 20. Substantially, thedeformed connection sections 30 are normal to an axis of the heat pipe 20 (as shown inFIGS. 2C and 2D ). - As aforesaid, the
deformed recesses 123 are arranged along the length of therib 12 at intervals (as shown inFIG. 2B ). However, the arrangement of thedeformed recesses 123 is not limited to the above. Alternatively, the deformed recesses can be continuous linear recesses or elongated recesses arranged section by section or partially formed on the rib according to requirements. In another embodiment, as shown inFIG. 3A , thedeformed recesses 123 a are disposed on the front edge and rear edge of therib 12. In still another embodiment, as shown inFIG. 3B , thedeformed recesses 123 b are disposed at the middle of therib 12. In still another embodiment, as shown inFIG. 3C , thedeformed recesses 123 c are disposed on the front section and rear section of therib 12. In still another embodiment, as shown inFIG. 3D , thedeformed recesses 123 d are elongated recesses formed on therib 12 section by section. In still another embodiment, as shown inFIG. 3E , thedeformed recesses 123 e are elongated recesses extending from the front edge to the rear edge of therib 12. - It should be especially noted that as shown in
FIGS. 2B , 2C and 2D, multipledeformed connection sections 30 are locally formed between the mating faces of theribs 12 and theheat pipe 20 and arranged along the length of theribs 12 at intervals (as shown inFIGS. 2C and 2D ). Eachdeformed connection section 30 includes a deformed raisedportion 31 and a deformed recessedportion 32. The deformed raisedportion 31 is formed on thelower surface 122 of therib 12. The deformed recessedportion 32 is formed on thesurface 21 of theheat pipe 20. By means of the restriction and tight fit and engagement between the deformed raisedportion 31 and the deformed recessedportion 32, thesurface 21 of theheat pipe 20 fitted in the receivingchannel 11 of theheat dissipation board 10 is interfered with. The interference force is normal to the axis of theheat pipe 20 so that theheat pipe 20 is prevented from being extracted out of the receivingchannel 11 along the length thereof (in a direction parallel to the axis of the heat pipe 20). - In conclusion, in the present invention, the mating faces of the
ribs 12 on two sides of the receivingchannel 11 of theheat dissipation board 10 and theheat pipe 20 are locally (or continuously) deformed to form at least onedeformed connection section 30 for tightly fitting and connecting theheat pipe 20 with theribs 12. Thedeformed connection section 30 is substantially normal to the axis of theheat pipe 20 so as to apply an interference force to theheat pipe 20 to prevent theheat pipe 20 from being extracted out of the receivingchannel 11 along the length thereof (in a direction parallel to the axis of the heat pipe 20). - The present invention has been described with the above embodiments thereof and it is understood that many changes and modifications in the above embodiments can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
