The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Shown in Fig. 1-3, a kind of three-dimensional conductive structure that provides for the utility model embodiment, be used for playing heat radiation and heat conducting effect at heat abstractor, comprise temperature-uniforming plate 1, temperature-uniforming plate 1 comprises the bottom block 11 with cavity, be fastened on the plate lid 12 on the bottom block 11, be located at first capillary structure 13 in bottom block 11 cavitys and be filled in the interior working fluid (not shown) of bottom block cavity, bottom block 11 is provided be used to the tracheae 14 that vacuumizes with the faying face place of plate lid 12, be connected with at least onely for being connected with external component and the heat pipe 2 of heat conduction on the plate lid 12, the inner chamber of heat pipe 2 is communicated with the cavity of bottom block.First capillary structure 13 can adopt the mixture of sintered body, grid body, carbon fiber and graphite or above-mentioned substance to make, working fluid can adopt the lower liquid of boiling point such as ethanol, distilled water, like this than being easier to evaporative condenser, thereby can absorb heat faster and dispel the heat; Heat pipe 2 not only plays a part heat radiation and conducts heat, and also is used for being connected with outside other parts, for example is connected with the radiating fin group that radiating fin constitutes.The three-dimensional conductive structure that the utility model provides, it is combined with temperature-uniforming plate by heat pipe is set, lower boiling working fluid draw heat and evaporating from the temperature-uniforming plate, steam enters heat pipe, and then condensation heat radiation, thereby spatially expanded the functional structure of heat radiation and the heat transfer of temperature-uniforming plate further, improved the ability of its heat radiation and heat transfer.
The inwall of heat pipe 2 is covered with second capillary structure 21, the material of second capillary structure 21 can be selected to make with first capillary structure, 13 identical materials, second capillary structure 21 is little with the inwall thermal contact resistance of heat pipe 2, capillary force is strong, be convenient to working fluid and in time be back to the temperature-uniforming plate inner chamber, thereby form the heat absorption evaporation, the circulation heat radiation of condensation heat radiation.
Offer the pore 120 that wears for heat pipe 2 on the plate lid 12, heat pipe 2 is communicated with bottom block 11 by pore 120.
Plate covers on the face relative with the cavity of bottom block 11 on 12 and is covered with the 3rd capillary structure (not shown), thereby the inwall of the inner chamber of whole temperature-uniforming plate all is covered with capillary structure, form a bigger evaporative condenser face, steam flows in the hollow position of the inner chamber of temperature-uniforming plate and heat pipe, condensed working fluid refluxes by the capillary structure that is overlying on the inwall, the working fluid evaporation of constantly absorbing heat, the continuous condensation heat radiation of steam, thus make heat radiation and conduct heat and can constantly circulate.
Edge along pore 120 convexes with pipe box 121, pipe box 121 can play guiding when heat pipe 2 and plate lid 12 is connected, simultaneously, because of plate lid 12 thinner, be connected with heat pipe 2 only according to plate lid 12 and be not enough to fix well heat pipe 2, therefore, pipe box 121 also plays a part to strengthen heat pipe 2 and plate lid 12 steadiness that are connected, and heat pipe 2 can be connected in by the mode of welding on the plate lid 12.
In the present embodiment, heat pipe 2 is provided with six, and described six heat pipes are two rows and are distributed in side by side on the plate lid 12, thereby spatially expanded the function of temperature-uniforming plate 1 heat conduction and heat radiation, the number of heat pipe 2 arranges very few, is not enough to play the ability of 1 heat radiation of expansion temperature-uniforming plate and heat transfer, if arrange too much, bring constant then can for the manufacturing of temperature-uniforming plate, therefore, in the present embodiment, arrange six comparatively suitable, certainly, the number of heat pipe is not regarded it as and is limited.
As shown in Figure 4, tracheae 14 is located at the place, position, angle of temperature-uniforming plate, and correspondingly, the superposed surfaces place of bottom block 11 and plate lid offers the pipe hole that air supply pipe 14 wears.
As shown in Figure 5, convex with reference column 110 on the face of fitting with the plate lid on the bottom block 11, reference column 110 is located at the place, position, angle of bottom block 11, being arranged so that of reference column 110 can be located when plate lid fastens with bottom block accurately and rapidly, thereby enhance productivity, guarantee the welding quality of plate lid and bottom block.
As shown in Figure 1, the place, position, angle of plate lid 12 is provided with the breach 122 that is complementary with reference column 110, so that plate lid 12 and accurately contraposition of bottom block 11.
The three-dimensional conductive structure that the utility model provides, it has good heat radiation and heat transmission function, thereby in applying to heat abstractor the time, it can be rapidly, equably with other parts in the heat transferred heat abstractor with further heat radiation, simultaneously self also play a part heat radiation, thereby can improve the integral heat sink efficient of heat abstractor.
Below only be preferred embodiment of the present utility model, not in order to limiting the utility model, all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace or improvement etc., all should be included within the protection domain of the present utility model.
