Description

The beaming type heat-pipe radiator

Technical field

The utility model relates to a kind of beaming type heat-pipe radiator, belongs to the hot pipe technique field, is applicable to the hot side heat radiation to various refrigerators, is specially adapted to the hot side heat radiation of mini-bar, water dispenser semiconductor chilling plate.

Background technology

The present heat pipe-type silk screen radiator that uses, mainly have following problem: 1, this product solder joint is many, and weld seam is many, leak rate height, difficult quality guarantee; 2, in tube passage above the evaporator section and square box when welding, tend to make ips to attenuate, have in addition weldering stifled, have a strong impact on the conducted power of heat pipe because it is snakelike trend, the pipe bending is many, distance is long, so flow resistance is big; 3, because its welding job amount is big, thus the cost height, the percent defective height.

Summary of the invention

At the technical problem of above-mentioned existence, the utility model provides that a kind of solder joint is few, flow resistance is little, do not have leak, lower-cost beaming type heat-pipe radiator;

The technical measures of taking that achieve the above object are: the utility model is made of heat pipe and heat radiation silk screen, be characterized in, by metal tube one end closure, the other end is fixed with the topping up pipe, be coiled into: on, following two ends are several horizontal compact arranged straightways respectively, its left side, scatter respectively and be aplysia punctata in right both sides, the middle part is the straightway that vertically uniformly-spaced is arranged in parallel, along on the straightway gabarit center line certain distance, the equally spaced iron wire that laterally is fixed with in lower part is netted, play thermolysis, with the straightway center line to curving the condensation segment that the two-layer metal tube that is arranged in parallel forms heat pipe, two ends abut against the evaporator section of a plurality of heat pipes of boundling tube bank formation together, and the middle part of boundling tube bank casts in the aluminium block, and four jiaos of aluminium block are provided with the hole, be used for fixing heater members, the boundling tube bank also can be embedded in the copper billet;

Advantage of the present utility model: 1, solder joint seldom, 1～2 little solder joint does not only have and leaks, qualification rate reaches 99.99%; 2, because the utility model is the heat pipe passage that curves on bending die, can not produce the problem that the passage internal diameter diminishes, and when working medium undergoes phase transition in pipe straight on, straight current downflow, flow resistance is minimum, because make a pipe form tens pipes through coiling at the evaporator section boundling, its heat transfer power has improved tens times, because evaporator section is made up of tens pipes, its evaporating surface increases several times, the corresponding reduction several times of its thermal resistance than the evaporating surface of existing evaporimeter; 3, because the utility model structure does not have welding work substantially, thereby do not have waste product substantially, reduce so cost has by a relatively large margin, performance increases, and mini-bar, water dispenser industry are of value to the expansion batch process after adopting the utility model.

Fig. 1 is that Fig. 2 is the front-view schematic diagram of an embodiment of the utility model to the coiled metal pipe before curved and the front-view schematic diagram of butt-joint iron wire assembly, and Fig. 3 is the side view of Fig. 2, and Fig. 4 is the A-A partial sectional view of Fig. 2.

The specific embodiment

In conjunction with the accompanying drawings structure of the present utility model and embodiment are described as follows; The utility model is made of heat pipe 1 and heat radiation silk screen 2, be characterized in, be about 9 meters by group's enlightening pipe 1, about 6 millimeters of external diameter, one end soldering and sealing, the other end is welded with topping up pipe 3, be coiled into: on, following two ends are 5 horizontal compact arranged straightways respectively, its left side, scatter respectively and be aplysia punctata in right both sides, the middle part is 9 straightways that vertically uniformly-spaced are arranged in parallel, along on the common about 60 millimeters distances in straightway gabarit center line both sides, the lower part uniformly-spaced horizontal butt-joint of 7-10 millimeter has the iron wire 2 of 2 millimeters of diameter phi 1-φ to be netted, with the straightway center line be benchmark on bending die to curving the condensation segment that two-layer each 9 metal tube that is arranged in parallel form heat pipes, the two-layer 20-40 millimeter that is spaced apart, two ends abut against the evaporator section of a plurality of heat pipes of boundling tube bank formation together, the middle part of boundling tube bank casts in the aluminium block 4, four jiaos of aluminium block are provided with hole 4a, radiator (except that aluminium block) is done the surface treatment of electrophoretic enamelling, in group's enlightening pipe, pour into R134A, heat-pipe working medium such as R22 or ammonia 5, seal, flat to aluminium block left side facing cut, be used for fitting with heater members.

Operation principle of the present utility model: the hot junction of aluminium block left surface and TEC is screwed, and when heat imported on the aluminium block, heat was transmitted to the heat pipe evaporator section of the boundling in the aluminium block very soon.Liquid working substance heat absorption in each evaporator section is evaporated, and flows to the heat pipe condenser section on radiator top, and by the radiating surface air heat radiation of being made up of the iron wire of a lot of butt-joints on the condensation segment pipe towards periphery, steam condenses into liquid after emitting heat in pipe.Liquid flows back to the evaporator section of bottom boundling at gravity effect lower edge inside pipe wall, continues the heat absorption evaporation, dispels the heat to top, so circulates endlessly, becomes a kind of radiator efficiently.See by the example shown in the figure, 10 pipe boundlings are arranged at the boundling place, and (see figure 4) is except that two together, and all the other the every interior steam of pipe can flow to two ends, just is equivalent to 18 evaporator sections, work equally together with 18 heat pipes, so greatly improved the ability to work of heat pipe.Simultaneously, because of the evaporator section in the aluminum pipe has 10 pipes, the disengagement area in the pipe is very big, and the evaporation thermal resistance significantly reduces, and has improved the efficient of radiator.Be of a size of 4 * 4cm as the aluminium block heating surface, the disengagement area of former square box type evaporimeter is 16cm ²And the evaporator section of forming by the pipe of 10 long 4cm, the internal diameter of every pipe is 0.5cm, then disengagement area is π * 0.5 * 4 * 10=62,8cm ², the evaporator section thermal resistance of therefore forming one of main heat group of radiator only is 16 ÷, 62.8 ≈ 0.25 of former square box type.
