Description

The heat pipe construction of sectional heat conduction

Technical field

The utility model relates to a kind of heat pipe, especially relates to the heat pipe construction of sectional heat conduction.

Background technology

Rapid development along with the 3C scientific and technological industry, various 3C electronic product constantly presents novelty and progressive design on its effect, but along with electronic product when effect promotes, also derive the problem of product internal heat dissipating, therefore, most electronic product all disposes radiating module in order to get rid of the heat energy of product inside.

With the computer product is example, if the heat energy that the electronics spare part is produced can't be got rid of, then can cause temperature to raise gradually, and make computer overheating cause maybe can't turning round when machine, therefore general personal computer all is equipped with fin and radiator fan, fin is the sheet metal that a surface has many fins, be used to reduce the temperature of computer equipment, and this fin is to increase area of dissipation, the eliminating of heat energy still need by around air-flow got rid of, therefore brush fin by fan and heat energy taken away.But therefore above-mentioned fin can't be got rid of heat at short notice because the efficient of heat conduction is not good in casing; Therefore, develop the heat dissipation technology-heat pipe that a kind of advanced person.

Heat pipe is the closed metal pipe, includes an amount of working fluid such as pure water or acetone; When the end (heating end) of heat pipe when being heated, because working fluid is under vacuum state, therefore workflow is known from experience the generation vapour pressure, this steam will flow to the lower other end of pressure (colling end), and condense and discharge the latent heat of condensation at this end, condensed working fluid is back to fire end via capillary force again, therefore can constantly evaporate and condensation to reach the purpose of heat transfer.

Please refer to TaiWan, China patent announcement I250913 number, heat pipe traditionally is the metal body of hollow, and the suction by working fluid in this metal body/heat release circulation reaches the effect of heat radiation.Yet, concerning the built-in system of computer, for asking preferable radiating effect, each high temperature heat source all needs to be equiped with heat pipe, for example the south bridge on the motherboard, north bridge chips or central processing unit need different heat pipes respectively, and not only cost significantly improves, and often have been covered with many heat pipes in the computer, also cause easily at extremely limited enclosure space to produce conflict and can't install other electronic equipment, and the disappearances such as having no elasticity that becomes is installed in the configuration of heat pipe.

The utility model content

Main purpose of the present utility model is to provide a kind of heat pipe construction of sectional heat conduction, it can form the above heat radiation circulation of two sections, quicken the back-flow velocity of the working fluid of liquid phase, process advantage simple and with low cost except reaching the configuration elasticity and the purpose of great heat radiation effect that improves heat pipe, also having.

For achieving the above object, the metal body that the disclosed possible technique scheme of the utility model mainly has hollow, suction/heat release circulation by working fluid in this metal body reaches the effect of heat radiation, the utility model is to have at least one pressing section between the end of metal body and end, this pressing section possesses the recess that relative this metal body is depression, and this recess is to engage with the opposite side wall of this metal body, and constitute the disconnected sealing surface that forms by this recess at the inwall of this metal body, thus, can in heat pipe, distinguish different heat radiation sections, and then make two heat radiations circulations more than the section of formation on single heat pipe.

Thus, can in heat pipe, be separated out different heat radiation sections, and then make on single heat pipe and to form two heat radiations circulations more than the section, thereby can quicken the back-flow velocity of the working fluid of liquid phase, process advantage simple and with low cost except reaching the configuration elasticity and the purpose of great heat radiation effect that improves heat pipe, also having.

The specific embodiment

Relevant detailed description of the present utility model and technology contents, existing accompanying drawings is as follows:

Please refer to Fig. 1, it is the structure chart of the utility model preferred embodiment, as shown in the figure: the utility model is a kind of heat pipe construction of sectional heat conduction, the metal body 10 (for example being copper pipe) that mainly has hollow, suction/heat release circulation by working fluid in this metal body 10 reaches the effect of heat radiation, principal character of the present utility model is to have at least one pressing section 20 between the end of this metal body 10 and end, on this pressing section 20, possesses the recess 21 that relative this metal body 10 is depression, and this recess 21 is to engage (please refer to Fig. 2) with the opposite side wall of this metal body 10, or the opposite side wall has corresponding recess 21 equally, and constitute the disconnected sealing surface 30 that forms by this recess 21 at the inwall of this metal body 10, this metal body 10 is separated out by recess 21 can inhale respectively/the first section a and the second section b that heat release circulates.

And the cross section of this metal body 10 can be according to the present embodiment structure that like that roughly is square, and also can be circle, the cross section of this metal body 10 waits other shape, also can implement technological means of the present utility model, for cooperating the position or the structure of thermal source, this metal body 10 itself can be the strip body, or have at least one inflection point and become bending body etc., can not hinder enforcement of the present utility model yet.
