Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, 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 explain the utility model, and be not used in restriction the utility model.
As depicted in figs. 1 and 2, be the exemplary plot of the flat heat pipe that the utility model embodiment provides, it comprises one flat 1, at least one body 2 be located on flat 1, particularly, flat 1 has at least one docking area 11.When only arranging a body 2, the area of section of the comparable body of area of section 2 of flat 1 is bigger.The lower end of body 2 is the openend of docking with the docking area 11 of flat 1, and the upper end of described body is blind end; As a detailed description of the invention, the conventional process that the blind end of body 2 can adopt heat pipe to process, be namely processed into contracting mouth structure, thus got up by this end-enclosed, this kind of technique is the conventional processing technology of heat pipe, does not carefully state at this; The inwall of body 2 and the docking area 11 of flat 1 all has capillary structure 3, namely the end being equivalent to body 2 also has capillary structure 3, directly contact with thermal source for flat 1, be namely equivalent to flat heat pipe and directly contact with thermal source, thus can rapidly heat be passed.
The flat heat pipe that the utility model provides, it arranges one flat 1 by the end, openend in body 2, because this flat 1 has flat surface, thus directly can contact with thermal source, and the surface of the docking area 11 that flat 1 is connected with the openend of body 2 has capillary structure 3, thus be namely equivalent to the end of flat heat pipe is directly contacted with thermal source, the sidewall of body 2 also has capillary structure 3, thus can directly by the heat conduction of thermal source and distribute, and the volume of flat 1 can do less, thus for small volume, the heater element (such as high-power LED lamp pearl etc.) that caloric value is larger, it can not by the restriction of installing space, efficiently, rapidly for it dispels the heat.
As a better embodiment, the capillary structure 3 on the docking area 11 of flat 1 should be covered with whole docking area, like this, can strengthen heat transfer and the heat-sinking capability of this flat heat pipe.
As a better embodiment, capillary structure 3 on the inwall of body 2 and the docking area 11 of flat 1 is formed in one, like this, the slitless connection of capillary structure on the docking area 11 of flat 13 and the capillary structure 3 on the inwall of body 2 can be realized, thus reduce heat transfer retardance, improve heat transfer and the heat-sinking capability of this flat heat pipe.
As an embodiment, the cross section of body 2 can be circle, and certainly, the cross section of body 2 also can be other shapes such as square, regular polygon.
As an embodiment, as shown in Figure 2, described docking area 11 is formed on the bottom being provided with the first groove 12, first groove 12 for flat 1; The openend of body 2 is placed in this first groove 12, adds man-hour, is positioned over by body 2 in first groove 12, and the openend of body 2 and the diapire of the first groove 12 abut against.Traditional heat pipe technological method for processing plug is inserted in the (upper end open of body in the inner chamber of the body with openend and blind end, lower end is blind end, plug inserts from openend), then metal dust is filled at the gap place between plug and the inwall of body, carry out sintering again and form capillary structure, the openend of body then adopts contracting mouth technique, forms contracting mouth to close the inner chamber of this body, thus, its two ends of final heat pipe are closed state.But in this kind of processing mode, because the bottom of the bottom surface of the end of the lower end of plug and the blind end of body offsets, thus the inwall of the blind end of body is not then filled attachment by metal dust, after sintering, the blind end inwall of body does not then have capillary structure to adhere to, and causes the heat conduction of body and radiating effect not good.
In the present embodiment, as shown in Figure 3 and Figure 4, for making that docking area 11 that flat 1 connects with body 2 openend forms capillary structure 3, promote heat conduction and the heat-sinking capability of flat heat pipe, can the lower end of plug 4 be made cone-shaped, form pointed cone portion 41, as shown in Figure 4, because plug 4 is in cone-shaped, the pointed cone portion of plug 4 and the diapire of the first groove 12 offset, thus when filling metal dust, the diapire of the first groove 12 nearly all can be filled by metal dust, after sintering, the bottom of the first groove 12 is formed with capillary structure 3, namely the openend being equivalent to body 2 also has capillary structure 3.When directly contacting with thermal source for flat 1, by the heat conduction of capillary structure 3, the heat of thermal source can be made to be dispelled the heat by whole flat heat pipe.
Alternatively, as shown in Figure 5, the outer wall that flat 1 can be arranged at least one inwall of the first bulge loop 13, first bulge loop 13 and the openend of body 2 fits, and what now docking area 11 enclosed for this first bulge loop 13 encloses district.What the openend of body 2 was directly inserted in that the first bulge loop 13 encloses encloses in district, and the lateral wall of body 2 abuts with the madial wall of the first bulge loop 13, like this, guide effect can be played on the one hand for the arrangement of body 2, on the other hand, body 2 can be made more firmly to be connected on flat 1, the mode of welding between body 2 with flat 1, can be taked to be fixedly connected with.
As another embodiment, flat 1 has at least one second bulge loop, the inwall of the outer wall of the second bulge loop and the openend of body fits (scheming not shown), and what now docking area enclosed for the second bulge loop encloses district.Thus the object be firmly connected to by body 2 on flat 1 can be reached equally.
As an embodiment again, as shown in Figure 6, flat 1 can be arranged at least one second groove 14, the week of the second groove 14 is along being provided with convex tendon 141, docking area 11 is then the diapire of the second groove 14, similarly, body 2 can be made firmly to be connected on flat 1.
As an embodiment, flat 1 can be square, and as shown in Figure 1, certainly, the shape of flat 1 also can be the shape such as circle, polygon, and its shape suitably can be arranged according to the position of thermal source and actual conditions.
As an embodiment, as shown in Figure 7, flat 1 also can arrange at least one boss 15, the outer wall of boss 15 and the inwall of body 2 fit, now docking area is the end face of boss 15, body 2 also can be connected on flat 1 by this kind of structure easily, also facilitates the processing of the capillary structure 3 in body 2 simultaneously.
As a better embodiment, being advisable in the middle part that body 2 is connected to flat 1, sheds with now can being conducive to even heat, be also conducive to flat heat pipe and be firmly connected with external device (ED).
The utility model additionally provides a kind of LED, comprise wiring board and be located at least one LED lamp bead on wiring board, it also comprises above-mentioned flat heat pipe, fit with the back side of wiring board for flat 1, and flat 1 with LED lamp bead just to setting, directly contact with wiring board due to flat 1, namely the end being equivalent to flat heat pipe directly contacts with thermal source, and the end of this flat heat pipe and sidewall all have capillary structure 3, thus can promptly, equably by heat conduction and distribute, this kind of application be particularly useful for high-power LED lamp pearl.
As a better embodiment, making the openend of body 2 and LED lamp bead just suitable to being set to, namely making the capillary structure 3 on the surface, docking area on flat 1 just right with thermal source, now more can be conducive to heat and conduct rapidly and distribute.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace or improvement etc., all should be included within protection domain of the present utility model.
