Abstract
The utility model relates to field of radiating, is specifically related to a kind of phase-change heat fin.Described heat radiation fin structure is hollow structure, and described hollow structure fills phase-change material, and described phase-change material flows freely in heat radiation fin.The utility model beneficial effect: the heat radiation fin of hollow and radiating surface are under synthesizing jet-flow effect, and good heat dissipation effect, heat conduction rate is fast, dispels the heat uniform and stable.
Description
Technical field
The utility model relates to field of radiating, is specifically related to a kind of phase-change heat fin.
Background technology
For being operated in periodically or the electronic device (as mobile electronic device and computer chip etc.) of pulse condition, phase-change energy storage type radiator is comparatively suitable heat management mode, has obtained in recent years and has paid close attention to widely.According to the permission working temperature (being usually less than 100 DEG C) of electronic device, in experiment, usually select the organic phase change material of paraffin class.But, because the conductive coefficient of paraffin is lower, in energy-storage units, easily form larger temperature gradient and affect its thermal response rates, therefore, the performance of phase-change energy storage type radiator be improved, be necessary to improve the capacity of heat transmission of phase-change material.
In recent years, due to the develop rapidly of nano material technology, the nanometer sized materials (as metal nanoparticle and carbon nano-tube etc.) of high heat conduction becomes new phase-change material heat filling.Nano filling has high specific area, the potentiality of its augmentation of heat transfer have more advantage than traditional material, and be expected to be formed dispersed better, more stable composite phase-change material, the novel phase-change material of high thermal conductivity of can thinking that one has " self-defined ".
The uneven participant of being heated of heat radiation fin causes local temperature too high, the uniformity no less important therefore dispelled the heat.
Utility model content
The method that the utility model utilizes phase-change material to fill, improves radiating efficiency, adopts hollow UNICOM structure, improves heat dissipation uniformity.
A kind of phase-change heat fin, comprises synthesizing jet-flow device and fin, it is characterized in that: described heat radiation fin structure is hollow structure, and described hollow structure fills phase-change material, and described phase-change material flows freely in heat radiation fin.
Described heat radiation fin becomes flat plate array structure, the heat radiation fin of hollow structure and the conducting of hollow structure radiating surface.
Described radiator is high heat conduction framework material, and phase-change material is the mixture of metal nanoparticle or carbon nanomaterial and paraffin.
Described phase-change material flows freely in hollow structure.
The utility model beneficial effect: the heat radiation fin of hollow and radiating surface are under synthesizing jet-flow effect, and good heat dissipation effect, heat conduction rate is fast, dispels the heat uniform and stable.
Accompanying drawing explanation
Fig. 1 is the utility model structure chart
Embodiment
As shown in Figure 1: described heat radiation fin 1 one-tenth flat plate array structure, the heat radiation fin of hollow structure and the conducting of hollow structure radiating surface.Described hollow structure fills phase-change material 2, and described phase-change material 2 flows freely in heat radiation fin, and it is inner that described phase-change material 2 is sealed in heat radiation fin 1.Internal paraffin is heated thawing, and heat is via metal nanoparticle or carbon nanomaterial, and to outdiffusion, the air-flow that the heat of diffusion is sprayed by synthesizing jet-flow device 3 is taken away.
