For convenience of description, at following embodiment, similar elements is to represent with same numeral.
Shown in Fig. 2,3,4, first preferred embodiment of the heat conducting heat-exchange device 3 of circulation channel formula of the present invention is to be applicable on the thermal source 4, and this pyrotoxin 4 is a CPU in this example; And comprise one and be sticked that urceolus 5, on this thermal source 4 is installed in inner core 6 in this urceolus 5, driving fit coats circular first ring seat 8 of two relative opening ports of the passage 7 that defines and circular second ring seat 9, at this urceolus 5 and inner core 6 and wears to tie this first ring seat 8 and extend into filling pipe 100, in this passage 7 and be filled in the fan 120 that working fluid 110 and in this passage 7 is cemented in a side of this urceolus 5 respectively.
This urceolus 5 is aluminium, copper metal or alloy metal or the good forming materials of other heat conduction, and comprise that the straight contact-making surface 51 on this thermal source 4, that can be sticked coats cylindric urceolus room 55, at least one limiting section that is formed on the inner surface of urceolus room 55 that defines in contrast to this contact-making surface 51 and the zigzag liquid collecting portion 53, that is formed on one inner surface 52 by a surrounding wall 54, and a plurality of outer surfaces 551 from this urceolus room 55 protrude out the urceolus radiating fin 57 of formation; This zigzag liquid collecting portion 53 can compile inflow for this working fluid 110; As shown in Figure 4, be to adopt a cone-shaped limiting section 56 and a semicircle limiting section 56 ' in this example.
This inner core 6 is aluminium, copper metal or alloy metal or the good forming materials of other heat conduction, be to be installed in the urceolus room 55 of this urceolus 5, and comprise and at least onely be formed on one outer surface 61 and fasten the capillary structure that fastening part, on the limiting section 56,56 ' at this urceolus 5 is formed on this outer surface 61 relatively, and a plurality of inner core radiating fins 65 that a center line towards this inner core 6 extends from one inner surface 64, and one by these inner core radiating fin 65 circles around the axis hole 66 that defines; Be to adopt a zigzag fastening part 62 that fastens at the cone-shaped limiting section 56 of this inner core 6 in this example, with a semicircle fastening part 62 ' that fastens at this semicircle limiting section 56 ', the inner surface 52 and the outer surface 61 of inner core 6 that makes this urceolus 5 defined a passage 7 with two relative opening ports jointly; Shown in Fig. 2,4,6, this capillary structure is that a plurality of intervals straight burr ditch 63 of being formed on the outer surface 61 of this inner core 6 (seen by vertical section and look the zigzag that can be as shown in Figure 6 by this straight burr ditch 63, or be as shown in Figure 7 stepped tooth colyliform), also can be changed to as shown in Figure 8 twill ditch 63 ', or be designed to horizontal ditch 63 as shown in Figure 9 "; This inner core radiating fin 65 has a plurality of its lip-deep straight burr ditches 651 that are formed on, to increase its cooling surface area; This axis hole 66 can be solid for semicircle radome fairing 130 plugs, and the air-flow that this fan 120 is guided is concentrated and blowed to this inner core radiating fin 65.
This first ring seat 8 is seen to look by section and is the T font, and driving fit is at a top opening port 71 of this passage 7.
The section of this second ring seat 9 also is the T font, and driving fit is at an end opening port 72 of this passage 7.
The bottom section 101 of this filling pipe 100 extend into this passage 7, and top section 102 protrudes out this first ring seat 8.
This working fluid 110 was for generally having the fluid of thermal evaporation, the cold reduction characteristic of chance; Be to enter in this passage 7, and after packing job is finished, strengthen the top filling mouth (figure does not show) of airtight this filling pipe 100 in moment high temperature spot welding mode via these filling pipe 100 fillings.
This fan 120 is the limits, top side that are cemented in this urceolus 5, borrows the guide functions of this kuppe 130 that air quantity will be concentrated and blows to this inner core radiating fin 65 and take away heat, and comprise that one can fasten spacing hole clipping 121 for the top section 102 of this filling pipe 100.
During use, when the temperature of this thermal source 4 rises, with the working fluid 110 that is positioned at this liquid collecting portion 53 is concentrated be subjected to heat excite after, produce phase transformation rapidly (after promptly the working fluid 110 of liquid state as shown in Figure 5 is vaporized the high temperature and high pressure gas of formation shown in big arrow, by the effect of capillary pressure difference, aforementioned high temperature and high pressure gas then moves to the capillary structure place of low-temp low-pressure shown in small arrow, relend and help capillary structure and outside air convection to carry out heat exchange to reach condensation, condensed working fluid 110 also can add that rapid backflow of gravity own comes together in this liquid collecting portion 53), it is different from general heat-exchange device 1 shown in Figure 1 and disperses and can't assemble because of straight diapire 131 can make the energy of the superincumbent working fluid 15 of distribution, and the present invention can obtain the good heat transfer effect relatively.
In addition, as Fig. 3, shown in 5, the formed capillary pressure of the capillary structure of inner core 6 of the present invention is poor, do not make the working fluid 110 rapid condensations of gaseous state shape only, come together in this liquid collecting portion 53 (promptly forming the working fluid 110 of liquid state) with adding rapid backflow of condensation working fluid 110 self gravitations, to improve hot transfer efficiency, can form outside heat radiation with the air heat exchange if add this urceolus radiating fin 57, and these fan 120 air-guidings of arranging in pairs or groups pass the of such a size cooling surface area of this inner core radiating fin 65, and take away the characteristic of inner waste heat, but with the accelerated heat conduction to reach the effect of good heat exchange.
Shown in Figure 10,11,12, it is second preferred embodiment of the heat conducting heat-exchange device of circulation channel formula of the present invention, its place that is different from first preferred embodiment is: also comprise one be cemented on the top opening 81 of this first ring seat 8 and can be communicated with this passage 7 seal seat 140, this seals seat 140 and has a filling mouth 143 that extends to inner surface 142 and be communicated in this passage 7 from outer surface 141, and one around and be communicated with this filling mouth 143 and seal the conjugate foramen 144 of the outer surface 141 recessed formation of seat 140 from this; This heat-exchange device 3 is not provided with filling pipe 100 as shown in Figure 2, but also comprise a seal 150 that is enclosed on this filling mouth 143, an and closely connected locating piece 160 on sealing body 150, and make an outer surface 161 of this locating piece 160 concordant with the outer surface 141 that this seals seat 140, to form the heat-exchange device 3 that a flat seals and can keep the flat appearance degree, and process apparatus is simpler, relatively the practical value height.
In actual the use, can utilize a degasification filling needle 170 puncture to enter this locating piece 160 with seal 150 and stretch in this passage 7 and carry out degasification, filling, when this degasification filling needle 170 is extracted sealing body 150, borrow the elastic-restoring force of sealing body 150 to seal the hole that this degasification filling needle 170 punctured, and strengthen a perforation 162 (solder joint 180 as shown in figure 12) of airtight this locating piece 160 in moment high temperature spot welding mode.
As shown in figure 13, it is the 3rd preferred embodiment of the heat conducting heat-exchange device of circulation channel formula of the present invention, its place that is different from first preferred embodiment is: two end opposite of this heat-exchange device 3 are equipped with an oral siphon 190 and an outlet pipe 200 respectively, heat by this thermal source 4 excites and the rapid liquid (figure does not show) that heats in the inner core 6 of flowing through, and forms a water heater purposes.
