Detailed description of the invention
Below in conjunction with the accompanying drawing of the present invention, technical scheme is clearly and completely described,
Obviously, described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art are obtained under not making creative work premise
The every other embodiment obtained, broadly falls into the scope of protection of the invention.
Embodiment 1
The bulkhead lamp phase-transition liquid of the present invention, by distilled water, dehydrated alcohol and edible vegetable oil according to 5:80:15
Parts by weight make.
Embodiment 2
The bulkhead lamp phase-transition liquid of the present invention, by pure water, dehydrated alcohol and edible vegetable oil according to 80:15:5
Parts by weight make.
Embodiment 3
The bulkhead lamp phase-transition liquid of the present invention, by pure water, dehydrated alcohol and edible vegetable oil according to 80:19:1
Parts by weight make.
The bulkhead lamp phase-transition liquid that the present invention provides, by water, dehydrated alcohol and edible vegetable oil according to 5-80,
The weight portion composition of 15-80,1-15, wherein, the water of use is distilled water or pure water.The present invention selects this
A little components are mainly in view of: water, dehydrated alcohol heat conduction interconvertibility good, and dehydrated alcohol can improve phase transformation
The hot property of liquid；The heat conductivity of edible vegetable oil is big, is possible to prevent the hydrogenization of phase-transition liquid；Examine simultaneously
Consider to water, dehydrated alcohol and edible vegetable oil boiling point under vacuo be 32 DEG C respectively, 40 DEG C with 70-95 DEG C.
Owing to, in the formula of this phase-transition liquid, the total amount of water and dehydrated alcohol accounts for more than the 85% of total weight parts, therefore
In phase-transition liquid, the liquid of more than 85% begins to boiling temperature reaches about 40 DEG C when, is converted into gas,
And the boiling point of the remaining vegetable oil less than 15% is higher, but its content is relatively low, therefore by whole phase-transition liquid
Boiling point slightly improves.Through repetition test, under vacuum conditions, the boiling point of the phase-transition liquid of this formula is 45 DEG C,
Specific experiment data such as table 1.Visible, the phase-transition liquid of the present invention contrasts traditional phase-transition liquid, not only heat-transfer rate
Faster, and boiling point is lower.
Simultaneously as the boiling point of vegetable oil is higher, it is possible to play the effect stablizing whole phase-transition liquid, work as temperature
When degree reaches 45 DEG C, whole phase-transition liquid will not be made quickly to vaporize, but make the vaporescence of phase-transition liquid present
The progressive process of one relative mitigation, does not results in phase-transition liquid vaporescence too fast and make aneroid in radiator
Body composition, and then cause the connecting portion temperature of radiator too high.
Table 1
| 95 DEG C of heating in water bath | Alcohol burner heats | Boiling point | |
| Tradition phase-transition liquid | 31 seconds are lasted from 10-60 DEG C | 28 seconds are lasted from 15-60 DEG C | 60℃ |
| The present invention | 27 seconds are lasted from 10-45 DEG C | 24 seconds are lasted from 15-45 DEG C | 45℃ |
Embodiment 4
The present invention also provides for a kind of bulkhead lamp radiator, as it is shown in figure 1, include body, thermal transfer plate, close
Capping plate, liquid injection pipe and phase-transition liquid, have a cavity in the middle of described body, the two ends of cavity pass with heat respectively
Guide plate, seal cover board connect.By the phase transformation cavity body structure of this hollow, effectively increase work area,
Strengthen passage of heat, can realize in the case of identical material, same volume, accomplish bigger power, and fall
Low production cost.The shaft section of thermal transfer plate is "convex" shaped.The ledge of "convex" shaped passes through oil pressure
After the cavity of machine press-in body, and its inwall compact siro spinning technology, the external connection of its base section and body, close
After capping plate is pressed into the cavity of body by hydraulic press, tight with the cavity inner wall of body by welding manner
Connect, it is ensured that its sealing.Liquid injection pipe is arranged on seal cover board, and the cavity periphery of body arranges multiple
The fin of shape.Fin is for being delivered to the heat of radiator in extraneous air.Merit according to operating mode lamp
Rate, it would be desirable to the component of phase-transition liquid be injected into Body Lumen, thermal transfer plate and seal cover board by liquid injection pipe
Formed container in, then to this container vacuum-pumping after, by liquid injection pipe compress so that it is seal, it is ensured that do not leak
Gas, liquid-impermeable.
The operation principle of bulkhead lamp radiator is as in figure 2 it is shown, after light fixture is lighted, the heat of light source is by warm
Conductive plate is delivered on the body of radiator, and a part of heat is directly distributed by the fin on body,
Another part heat is delivered to the phase-transition liquid in Body Lumen, and heat makes the temperature of phase-transition liquid raise, and works as phase transformation
Liquid reaches boiling point 45 DEG C when, starts to be converted into gaseous state by liquid, owing to the inner wall temperature of cavity is low,
After gas after conversion runs into the inwall of cavity, by gaseous state be converted into liquid and reflux.Pass through phase-transition liquid
It is converted into gaseous state by liquid, the heat in light fixture is taken in radiator, is converted into by gaseous state by phase-transition liquid
Liquid, is delivered to the heat in radiator the cavity inner wall of body, then is passed by the fin that body is peripheral
It is delivered in air, it is achieved the reduction of bulkhead lamp temperature.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited to
This, any those familiar with the art, in the technical scope that the invention discloses, can readily occur in
Change or replacement, all should contain within protection scope of the present invention.Therefore, protection scope of the present invention should
Described it is as the criterion with scope of the claims.
