Description
Technical field
The present invention relates to a kind of heat transfer unit (HTU), the particularly a kind of LED of can be applicable to high-power illumination field or the heat radiation device for loop heat pipe of employing enhanced evaporation section of application of the electronic component of radiating requirements is arranged.
Background technology
Great power LED is used in the illumination just more and more, and the great power LED cooling problem is still and hinders the difficult problem that the high-power LED illumination application is popularized rapidly at present.Most of electric energy of great power LED all are converted into conduction heat, in addition, several or a large amount of LED are placed in the module to reach required brightness, to cause the heat radiation difficulty, the led module temperature raises, cause the life-span of LED to be reduced, and quicken light decay, the efficient that influences elements such as led driver and the reliability of LED.
The Section Bar Heat Sinks of heat-pipe radiator and traditional natural heat dissipation relatively have many advantages such as heat transfer efficiency height, heat-transfer rate be fast, in light weight.Heat-pipe radiator is compared with the Section Bar Heat Sinks of traditional natural heat dissipation, reduce the volume of LED light fixtures such as LED street lamp, LED projecting lamp greatly and reduced weight, can under the prerequisite that effectively solves heat dissipation problem, realize the LED high-power illumination more than the 100W simultaneously easily, and have extremely strong cost performance, it will be a kind of trend of following LED heat radiation.
The present heat-pipe apparatus that generally adopts, the way that two block pressur plates are clamped the evaporation ends of heat pipe about the thermal source part generally adopts, this way has following shortcoming: one, mainly take away by heat pipe owing to thermal source part heat, the temperature at thermal source place is difficult to realize the equilibrium of thermal source place temperature because of the far and near different temperature difference that produce of distance heat pipe like this; Two, the evaporator section of heat pipe is clamped the realization thermo-contact by two block pressur plates up and down, because the roughness influence of clamp surface processing, heat pipe can not contact fully with pressing plate, causes the space to exist, and thermal resistance is big, has so just influenced the conduction of heat greatly.
Summary of the invention
The objective of the invention is to overcome the defective of existing heat pipe heat radiation mode, provide a kind of LED lamp to adopt the heat radiation device for loop heat pipe of enhanced evaporation section.
The technical scheme that purpose of the present invention realizes is: the LED lamp adopts the heat radiation device for loop heat pipe of enhanced evaporation section, comprise heat pipe, fin 5, hydraulic fluid 6, it is characterized in that, described heat pipe is the loop pipe with annular seal space that is provided with enhanced evaporation section 2, reflux section 3a, steam section 3b, the 3c of compensated chamber, condensation segment 1, enhanced evaporation section 2 is arranged on the thermal source back side of LED lamp, be pumped into suitable vacuum in the loop pipe, be provided with capillary structure 4, and being filled with an amount of hydraulic fluid 6, condensation segment is provided with fin 5.
Described enhanced evaporation section 2 cross sectional shapes are square or rectangle, and material is the metal material of high-termal conductivity, and enhanced evaporation section 2 is welded to connect with 3c of compensated chamber and steam section 3b respectively.Capillary structure 4 is arranged in the inner chamber of enhanced evaporation section 2 and the 3c of compensated chamber.
The LED lamp adopts the operation principle of the heat radiation device for loop heat pipe of enhanced evaporation section to be: enhanced evaporation section 2 directly fully contacts with the thermal source face, the heat that thermal source produces is delivered to the enhanced evaporation section 2 that heating surface area increases greatly, its interior capillary structure 4 also was heated when enhanced evaporation section 2 was heated, hydraulic fluid 6 in the capillary structure 4 just can flash to gas, and by the steam conduit on the capillary structure 4 along steam section 3b to condensation segment 1, taken away heat simultaneously; And in condensation segment 1, gas has been condensed into hydraulic fluid 6, and heat is discharged fin 5 to this district, and fin 5 contacts with extraneous air, and free convection or fan forced heat radiation by outside air are discharged into the external world with the heat on the fin 5; And the capillary force of capillary structure 4 makes hydraulic fluid 6 be back to the 3c of compensated chamber along reflux section 3a again, and arrives capillary structure 4.The flow circuit and the heat transfer process of a hydraulic fluid 6 have so been formed.
The present invention's compactness rational in infrastructure is manufactured easily, and heat transfer efficiency height, radiating rate are fast, be used for the heat radiation of LED light fixture, can effectively reduce the led module temperature, solve the great power LED cooling problem, improve the LED luminous efficiency, reduce the light decay speed of LED, prolong the service life of LED.Simultaneously, can reduce the weight of the volume and the reduction light fixture of LED light fixture, improve the adaptability and the scope of application of LED light fixture.Concrete advantage is:
One, the heat of thermal source generation is delivered to the enhanced evaporation section that heating surface area increases greatly, enhanced evaporation section directly fully contacts with the thermal source face, heating surface directly is heated simultaneously, realize the equilibrium of thermal source place temperature, solved thermal source place temperature that the conventional heat pipe technology causes owing to thermal source partly only depends on single heat pipe to be heated produces the temperature difference because of the far and near difference of distance heat pipe defectives;
Two, this device enhanced evaporation section directly fully contacts with the thermal source face, and heating surface directly is heated simultaneously, greatly reduces thermal resistance.Solve conventional heat pipe technology heat pipe and contacted not exclusively and caused the big defective that influences thermal conduction effect of thermal resistance with pressing plate.
