Abstract
The invention belongs to the technical field of heat pipe heat dissipation for LED lamps, and particularly relates to a gravity heat pipe radiator used in elevation-angle irradiation or depression-angle irradiation of LED projector lamps. The position of a light source and the position of a heat pipe radiator are reasonably selected on different planes of an evaporating cavity, so as to ensure that the whole heat pipe radiator is located above the arrangement plane of the heat pipe radiator all the time during rotation of the evaporating cavity, so that the projector lamp can realize omnibearing irradiation via gravity heat pipe heat dissipation, and thus extending the irradiation scope, lowering the cost and improving the heat dissipation efficiency.
Description
Technical field
The invention belongs to LED heat pipe heat radiation technical field, particularly relate to a kind of when LED projector lamp is faced upward and penetrated or shoot downward
The gravity force heat pipe radiator used.
Technical background
The most commonly used heat pipe heat radiation technology of high-powered LED lamp heat radiation at present.When LED light source is shot downward downwards, weight
Power heat pipe is easier to find the position of gravity circulation, such as patent: ZL201520281016.4, the pendulum of gravity assisted heat pipe in light fixture
Putting position and be generally positioned in the top of light source, enable to be gasified rapidly by hot working fluid in heat pipe rising, relies on gravity to make after catching a cold
With gradually refluxing, form the gravity circulation of the gas-liquid phase transition of working medium, and reach, with this, purpose of dispelling the heat, but, if in LED lamp
When light source is penetrated to facing upward, this gravity assisted heat pipe is difficult to find and promotes working medium to rely on action of gravity to realize the structure position of gas-liquid phase transition
Put, so often using antigravity heat pipe to solve this problem.Antigravity heat pipe is substantially more expensive, and radiating efficiency is relatively low,
Not can solve the heat dissipation problem of large-power lamp.If using what gravity assisted heat pipe solved LED light source to face upward the problem of penetrating,
So it is accomplished by the position finding gravity assisted heat pipe working medium can realize gravity circulation in fitting structure.
Summary of the invention
Present invention aim at providing a kind of gravity assisted heat pipe that all can be able to use in Projecting Lamp is faced upward and penetrated or shoot downward to dispel the heat
Device.
The overall technology design of the present invention is: with the evaporation cavity of hot-pipe system for design core, by the six of evaporation cavity
Select suitable light source position and heat-pipe radiator putting position to realize omnidirectional and the heat pipe work of Projecting Lamp on the body of face
The gravity circulation heat radiation of matter.
The evaporation cavity of hot-pipe system is square hexahedron, when level is put, is divided into: bottom surface, end face and four sides, the end of at
Face or the optional one side of end face place light source, for light-emitting area, after determining the rotation axis of evaporation cavity, two sides parallel with axis
Optionally one side can put face as heat-pipe radiator in face, evaporation cavity light-emitting area and the heat-pipe radiator face of putting are orthogonal
Cross facet, heat-pipe radiator is overall puts the perpendicular relation of putting in face with heat-pipe radiator, and evaporation tube is put with heat-pipe radiator
The perpendicular relation of putting in face, the evaporation mouth of heat-pipe radiator and refluxing opening are arranged at heat-pipe radiator and put on face or be arranged at
On two evaporation cavity sides vertical with rotation axis, it is used for connecting and fixing heat-pipe radiator.
The concrete technology design of the present invention also has:
For keep heat pipe action of gravity, when evaporation cavity horizontal positioned on the basis of, be set to 0 °, according to different heat-pipe radiators
Putting the selection in face, the light-emitting area of evaporation cavity can rotate in 10 ° of 170 ° of intervals clockwise, it is also possible to counterclockwise
Rotating in 10 ° of 170 ° of intervals, interval beyond this, the action of gravity of heat pipe can disappear.In evaporation cavity rotary course, heat
Tube radiator entirety is always positioned at heat-pipe radiator and puts the top in face.Evaporation tube and the heat-pipe radiator face of putting can also be to have
The inclination of certain angle connects, but will reduce between the rotatable area of evaporation cavity.
For obtaining preferable radiating effect, added with fin on heat pipe, it is possible to add fan air blast cooling, heat-pipe radiator is adopted
With the roundabout coiling of spiral, pipeline use the fourth of the twelve Earthly Branches structure that rises connect fin.
Heat-pipe radiator can use the one in single or multiple lift structure.
Technological progress acquired by the present invention is:
The plane that evaporation cavity is different rationally selects position and the position of heat-pipe radiator of light source, enables Projecting Lamp to rely on
Gravity assisted heat pipe heat radiation realizes omnidirectional.Owing to evaporation cavity light-emitting area and the heat-pipe radiator face of putting are that two square crossings are put down
Face, so, evaporation cavity on the basis of horizontal plane clockwise or counterclockwise time, evaporation cavity light-emitting area is capable of penetrating to facing upward
Shooting downward downwards, substantially achieve the omnidirectional relying on gravity assisted heat pipe heat radiation, its technological rationality is: at evaporation cavity not
Rationally select position and the position of heat-pipe radiator of light source in same plane, enable Projecting Lamp to rely on gravity assisted heat pipe heat radiation real
Existing omnidirectional, so, when evaporation cavity rotates or counterclockwise at 10 ° 170 ° clockwise on the basis of horizontal plane
During 10 ° 170 ° rotations, during in evaporation tube, heated gas is in rising passway, so working medium can rely on gravity in heat pipe
Effect forms the circulation of gas-liquid phase transition, thus reaches purpose of dispelling the heat.
