However, at present also in the presence of key technical problem --- the heat dissipation problem that LED is hindered to flourish.In the prior art,
Generated heat is conducted to cooling fin when usually LED is lighted：On the one hand, cooling fin has multiple radiating fins, makes heat dissipation
Piece group and air exchange and take away heat, and for better air circulation, it will usually install fan additional；On the other hand, cooling fin
Heat exchange is carried out with the liquid of flowing, as described in patent CN201513858U, uses divergence pumping equipment（Pump）Cause liquid circulation flow
It is dynamic, so as to improve the radiating efficiency of LED lamp.But above two heat dissipating method must all use additional power source（Such as
Fan, pump etc.）Gas or liquid is driven to flow, takes away the heat of cooling fin so as to improve the heat dissipation effect of LED.Therefore, no
It can avoid generating additional energy dissipation.

Specific embodiment
For that can further appreciate that the feature, technological means and the specific purposes reached, function of the present invention, with reference to
Attached drawing is described in further detail the present invention with specific embodiment.
As shown in Figure 1, present invention is disclosed a kind of LED lamps of liquid self circulation heat dissipation, including LED component 4 and dissipate
Hot body 3, LED component 4 are connect with 3 attachings of heat dissipation, the radiator 3 with heat absorption liquid case 12, and 12 attaching of heat absorption liquid case had
Fluid box 11 is crossed, cooling medium is installed in heat absorption liquid case and liquid transition case, liquid transition case passes through two check valves
Connection, one of check valve 51 make cooling medium that can only flow to heat absorption liquid case, another check valve from liquid transition case
52 make cooling medium that can only flow to liquid transition case from heat absorption liquid case.Check valve only has the function of one-way flow and closing,
The check valve is known technology, and in this not go into detail.LED component is mounted on the bottom surface of radiator, the bottom of heat absorption liquid case
Face is mounted on the upper surface of radiator.In order to ensure the normal operation of the liquid transition case of heat absorption liquid case, inside all have
Air.
In addition, check valve is integrated on partition board 6, liquid transition case 11 passes through 6 company of separating of partition board with heat absorption liquid case 12
It connects.
The cooling medium is cooling liquid 22 or cooling gas 21.In the present embodiment, medium selected as will be cooled down
Cool down liquid.
The quantity of the heat absorption liquid case and liquid transition case is both greater than equal to 1.
In addition, check valve can also be integrated in conduit, as shown in Figure 6, liquid transition case and heat absorption liquid case at this time
It is connected by conduit, is connected in particular by heat extraction conduit 71 and time cold conduit 72.
In fig. 1, LED lamp is under original state, and LED component 4 does not work, and empty calory generates.At this time two it is unidirectional
All in closed state, the cooling medium to absorb heat in Rose Box and liquid transition case is in same gas-liquid circle for valve 51 and check valve 52
Face 23.Check valve 51 is back cold check valve, and check valve 52 is heat extraction check valve.When LED lamp enters working condition, LED component 4
The heat of generation reaches the liquid 22 in heat absorption liquid case 12 through radiator 3, and evaporation rate adds after liquid 22 rises to certain temperature
Soon, as shown in Figure 2, check valve 52 switchs to opening by closed state automatically, the gas-liquid interface 23 in heat absorption liquid case 12
It begins to decline；The liquid of heat flow to liquid transition case 11 through check valve 52, is mixed with liquid cold in liquid transition case 11.It has served as
After the liquid crossed in fluid box 11 rises to certain altitude, check valve 51 switchs to opening by closed state automatically, while single
Closed state is switched to by opening automatically to valve 52, as shown in Figure 3, cold liquid is through check valve 51 in liquid transition case 11
It is recycled in heat absorption liquid case 12, is mixed with liquid hot in heat absorption liquid case 12 so that the liquid 22 in heat absorption liquid case 12
Temperature declines, and so as to which LED component 4 is more through 3 dispersed heat of radiator, effectively improves LED lamps cooling effect.Such as attached drawing
Shown in 4, when the certain altitude that the liquid in transition fluid box 11 declines, return cold check valve 51 and switch to close by opening automatically
Closed state.
As 22 temperature of liquid in heat absorption liquid case 12 gradually rises, LED lamp carries out attached drawing 2, attached drawing successively automatically
3rd, process shown in attached drawing 4, LED lamp can carry out the high lasting heat dissipation of radiating efficiency automatically.
It should be noted that these are only the preferred embodiment of the present invention, it is not intended to restrict the invention, although ginseng
The present invention is described in detail according to embodiment, it for those skilled in the art, still can be to aforementioned reality
The technical solution recorded in example is applied to modify or carry out equivalent replacement to which part technical characteristic, but it is all in this hair
Within bright spirit and principle, any modification, equivalent replacement, improvement and so on should be included in protection scope of the present invention
Within.
