Abstract
The invention belongs to the technical field of heat pipe heat dissipation and particularly provides a gravity heat pipe radiator which can be used in radiation rotation of an LED projection lamp. An evaporation pipeline and a return pipeline adopt a roundabout ascending coiling mode and are located in different parallel layers respectively, the heat dissipation area of a heat pipe can be increased to the maximum degree, and heat dissipation efficiency is improved. Functions of an evaporation opening, a return opening, the evaporation pipeline and the return pipeline can be exchanged in the clockwise and counterclockwise rotating process, the installation requirement for multi-angle irradiation of the lamp can be met to the maximum degree, and meanwhile gravity circulation smoothness of gas-liquid phase change of the heat pipe is ensured.
Description
Technical field
The invention belongs to heat pipe heat radiation technical field, refer to a kind of gravity force heat pipe radiator that can use in LED projector lamp shoots downward rotation especially.
Background technology
High-powered LED lamp adopts heat pipe heat radiation to be one of technical scheme of the best.Due to fitting structure restriction, how to allow heat pipe obtain maximum area of dissipation in limited space, the gas-liquid phase transition gravity circulation simultaneously enabling light fixture heat-pipe radiator in various angle of inclination keep clear again, this is the key of heat-pipe radiator design.A lot of heat-pipe radiator at present, due to stage construction structural design imperfection, the gas-liquid phase transition gravity circulation ensureing that heat pipe is unimpeded is difficult in lamp heat pipe radiator tilts to install, such as patent: ZL201420486399.4 " Combined heat pipe radiator used for large power LED lamp ", although this gravity force heat pipe radiator with branched structure effectively extends larger area of dissipation on narrow and small evaporation cavity, but in light fixture tilts, evaporate pipeline in branched structure, have downward bend, return line has upwards bend in branched structure simultaneously, Action of Gravity Field is caused to lose, make gas-liquid cycle not smooth, radiating effect is very poor.Solve the problem, must the circuit design of heat-pipe radiator, evaporation mouth and refluxing opening design, radiator top transverse tube and coupling part design in ingenious design, make gas-liquid phase transition unblocked under gravity.
Summary of the invention
The object of the invention is to provide a kind of can shooting downward with light fixture to rotate the gravity force heat pipe radiator of use, and its design feature is in certain structure space, obtain maximum heat pipe heat radiation area and the maximum rotation scope of application.
Technical solution of the present invention is: LED light source is in evaporation cavity bottom surface, and evaporation cavity is provided with evaporation mouth, refluxing opening, and evaporation mouth and refluxing opening are connected with evaporation pipe-line system and return line system.First will determine rotation, for the ease of describing, rotation is set to horizontal line, and corresponding every design will based on this, and evaporation cavity carries out clockwise around rotation or is rotated counterclockwise, and is the multi-angle irradiation of LED.The evaporation pipe-line system be connected from evaporation cavity and return line system lay respectively in two different planes, both all adopt roundabout rising to spiral by pipeline, top is transverse tube, evaporation transverse tube is identical with the level height of backflow transverse tube most significant end, the two has pipeline to connect on contour point, the level height of tube connector a little more than or equal the peak evaporating transverse tube and backflow transverse tube, rotation and transverse tube almost parallel; Refluxing opening, return line, backflow transverse tube are positioned at another plane, form two and are interconnected aspect, can configure fan, to promote radiating efficiency in hot-pipe system side or top with evaporation pipeline.The horizontal peak of evaporation transverse tube and backflow transverse tube is contour, simultaneously the level height of tube connector is greater than or equal to the peak of two transverse tubes, so just can ensure that the gas that radiator evaporates in transverse tube in rotation is in most significant end all the time, the naturally dirty formation return duct of condensed liquid, so the height design of these key links determines heat pipe whether can ensure the unimpeded of gas-liquid phase transition in rotation.Departed from the height design of these some positions, hot-pipe system cannot use in rotation.
Evaporation mouth and refluxing opening lay respectively at the both sides of rotation, evaporation cavity is in rotary course, on evaporation cavity, be positioned at high-end mouth for evaporation mouth, the mouth being positioned at low side is refluxing opening, is positioned at the high-end mouth of evaporation cavity and is more suitable for steam sprays in rotation, because evaporation transverse tube is in the high-end of radiator all the time in rotation, so, a whole set of heat-pipe radiator in rotation can the evaporation of self-assembling formation working medium, the Efficient Cycle of backflow.Along with hot-pipe system turning clockwise or being rotated counterclockwise around rotation, evaporation mouth and refluxing opening function can be changed mutually, and evaporation pipeline and return line function are also changed thereupon.
The technology of the present invention progress is:
Set evaporation pipeline, the coiled fashion of return line and connected mode, feature is that the height design of several key link determines heat pipe can ensure the unimpeded of gas-liquid phase transition in rotation.Evaporation pipeline and return line adopt roundabout upthrow winding mold formula, lay respectively in two different planes, can expand heat pipe heat radiation area to greatest extent, raising radiating efficiency.
Evaporation mouth, refluxing opening are distributed in the design of rotation both sides, ensure that evaporation mouth and refluxing opening and evaporate pipeline, return line suitable, be rotated counterclockwise in can exchange by practical function, adapt to the multi-angle irradiation installation requirement of light fixture to greatest extent, ensure that the gravity circulation of heat pipe gas-liquid phase transition is unobstructed simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described further; but it is not as a limitation of the invention; the content that protection scope of the present invention is recorded with claim is as the criterion, and any equivalent technical elements of making according to this description is replaced and modified, and does not all depart from protection scope of the present invention.
The present embodiment overall structure as shown in Figure 1, the evaporation cavity 1 first put in level determines rotation 2, then evaporation mouth 3 is set in the both sides of rotation, refluxing opening 4, drawing evaporation from evaporation mouth 3, pipeline 6 is upwards roundabout spirals, evaporation transverse tube 8 is formed to top, evaporation transverse tube and rotation 2 almost parallel, evaporation pipeline is all in same plane, the most significant end of evaporation transverse tube has tube connector 9, in another plane, backflow transverse tube 7 is extended to form by tube connector 9, and downward roundabout coiling forms return line 5, return line is all in same plane, be connected to bottom with refluxing opening 4.LED light source can be posted in evaporation cavity bottom surface, evaporation cavity around rotation suitable, be rotated counterclockwise, be the multi-angle irradiation of LED.
