Description
Technical field
It the utility model is related to heat dissipation technology, and in particular to a kind of energy-saving heat radiator.
Background technology
LED is light emitting diode (Light Emitting Diode) abbreviation, is a kind of New Solid cold light source, by one
Secondary optics, secondary optics device, LED core chip package and radiator composition.Rely primarily on light emitting diode, core
It is P-N junction.When applying forward voltage, the electron injection P areas in N areas, the hole in P areas enters N areas, into the minority carrier of other side
Son and the majority carrier in raw material region occur compound in the presence of electric field, and caused energy gives off as electrons
Come, realize lighting function, here it is LED principle of luminosity.
Relative to conventional illumination sources, LED lamp has following features：
(1) energy-conserving and environment-protective, energy consumption are low.LED is a kind of high-efficiency photoelectric converter, and under equal-wattage, its brightness is white
LO times of vehement lamp.The harmful elements such as LED is not mercurous, lead, are easy to recycle., can be directly sharp and LED uses dc source
With solar energy, the generating of wind energy, belong to green clean energy resource.
(2) long lifespan.Under normal usage, it is more than hour to reach 100,000 to LED for its operating time, much larger than common
2000 hours of incandescent lamp, reduce maintenance, the renewal cost of other many light fixtures, can be described as that " labor is forever to average family
Ease ".
(3) response time is fast, can adjust brightness and the color and luster of light, good with photosensitiveness.LED response time is exceedingly fast, and LED can be with
Its brightness is controlled by the change of electric current in control circuit, the change of color can be realized by different wave length LED configuration, just
Different color application demands can be reached.
LED has a good application prospect, and semiconductor adds electronic component very sensitive to temperature at present, therefore to electronics
The harmony of component keeping temperature, with greater need for effective heat dissipation design.Related Experimental Study shows that electronic component exceedes work
After making temperature, temperature often raises 10 degrees Celsius, causes the reliability decrease 50% of system.And it is limited by current semiconductor technology
Development and the shortage of high efficiency and heat radiation mode, LED luminous efficiency simply reach 10% to 20%, and remaining 80% multi-energy all can
Change into heat to distribute, in order to ensure the life-span, it is necessary to which luminescence chip temperature is maintained at into less than 110 degrees Celsius.Current
If LED chip heat can not distribute in time, the rise of LED chip temperature can be caused, and then have influence on LED luminous effect
Rate, life-span etc..And the heat-sinking capability of LED chip is limited, heat can only be delivered on radiator by way of heat transfer.Cause
This, LED heat dissipation problem, which has become, restricts the subject matter that LED develops to high-efficiency high power.
Utility model content

Put, gas column absorbs expanded by heating after heat, gas pressure rise, when pressure exceedes the resistance of condensing agent fluid column flows in closed loop copper pipe
During power (frictional force, gravity etc.), the condensing agent fluid column in closed loop copper pipe can be promoted to be flowed to red copper thermal column apical position；Red copper
For thermal column apical position away from thermal source, gas column causes gas column volume-diminished afterwards to the cold, and pressure can accordingly reduce, and high-low pressure difference is also
This flowing can be aggravated.In addition, the pressure between the adjacent bending segment of closed loop copper pipe is also incomplete same, it can also promote and condense
Agent is flowed at random in pipe；Gas column is condensing agent in pressure differential caused by the heat absorption expansion at red copper thermal column both ends and contract on cooling
The main drive of flowing, driven without consuming external work, this flowing realizes that heat is dissipated in closed copper pipe by red copper
Transmit and distribute to top in plume bottom.In addition, found by the thermal resistance parameters of detection red copper thermal column, this closed loop copper pipe and post
In the case that shape closed container is applied in combination, the thermal resistance of red copper thermal column is smaller than being used alone, and radiating efficiency is higher.
Preferably, the condensing agent in described closed loop copper pipe and column closed container uses acetone.Acetone has stronger
Volatility and moderate gas-liquid transition temperature, compare the condensing agent that is suitable as in the utility model and use.
Preferably, described closed loop copper pipe and column closed container are equipped with a topping up pipe and lead to inner chamber, on topping up pipe
The valve that can be closed and open is installed.Facilitate supplement and the replacing of condensing agent.

This flowing is realized that heat transmits in closed copper pipe 4 from the bottom of red copper thermal column 1 to top and distributed.
In above-mentioned implementation process, silica gel or weldering are filled with the gap between center cylindrical hole 11 and column closed container 3
Tin.Gap also results in that heat conduction is not smooth, and above-mentioned processing can avoid the heat conduction of gap band difficult.
In above-mentioned implementation process, the condensing agent in closed loop copper pipe 4 and column closed container 3 uses acetone.Acetone has
Stronger volatility and moderate gas-liquid transition temperature, compare the condensing agent being suitable as in the utility model and use.
3 and accompanying drawing 4, closed loop copper pipe 4 lead to its inner chamber provided with a topping up pipe 43 referring to the drawings；Column closed container is equal
Topping up pipe leads to its inner chamber provided with a liquid supplementation pipe 32.Topping up pipe 43 and liquid supplementation pipe 32 are mounted on the valve that can be closed and open
Door.Supplement and the replacing of condensing agent can so be facilitated.
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, can also be on the premise of this patent objective not be departed from one skilled in the relevant art's possessed knowledge
Make a variety of changes.It should be appreciated that all other specific embodiments based on the utility model are new in this practicality
Within the protection domain of type.
