Thermal transfer devices field is the utility model is related to, more particularly, to a kind of tree-like fin.
Background technology
In heat and mass engineering field, there are various thermal transfer devices（Heat abstractor）, including fin.Greatly
More heat abstractors are mainly undergone phase transition by working medium takes away heat, so as to complete radiation processes.The height of radiating efficiency, it is to fill
Put the working medium of absorption how efficiently phase transformation release heat.
Utility model content
The utility model is to overcome at least one defect described in above-mentioned prior art, there is provided a kind of tree-like fin, can
Fast and effeciently realize the purpose of heat transfer.
In order to solve the above technical problems, the technical solution of the utility model is as follows：
A kind of tree-like fin, including substrate, the substrate lower surface contact with thermal source, and upper surface of substrate offers groove
Road, the conduit are divided into some levels, and next stage conduit is formed by upper level conduit by bifurcated, filled with evaporation liquid in conduit.
In a kind of preferable scheme, each conduit of upper level is two conduits in next stage bifurcated.According to demand
Bifurcated number is adjusted, bifurcated number more at most radiating efficiency is higher.
In a kind of preferable scheme, the evaporation liquid is water.
In a kind of preferable scheme, the inwall of the conduit is made up of water wetted material.
In a kind of preferable scheme, the bottom of the conduit is made up of hydrophobic material.The purpose is to promote to evaporate liquid
Flowing and evaporation.Hydrophobe property can be obtained by certain surface treatment.
In a kind of preferable scheme, the substrate is metal material.
In a kind of preferable scheme, the substrate lower surface is black light-absorbing material.Inhaled using the characteristic of black light-absorbing
The heat radiation of thermal source is received, strengthens evaporation liquid phase-change heat in conduit, further improves radiating efficiency.
Compared with prior art, the beneficial effect of technical solutions of the utility model is：The utility model provides a kind of tree-like
Fin, including substrate, the substrate lower surface contact with thermal source, and upper surface of substrate offers conduit, if the conduit is divided into
Dry level, next stage conduit are formed by upper level conduit by bifurcated, filled with evaporation liquid in conduit.Liquid is evaporated in bifurcated step by step
Shunted step by step in conduit, capillary drive evaporation liquid, liquid is transported by evaporation and disperses heat, increased in tree-like conduit
Big heat is with extraneous contact area mode so as to reaching more preferable radiating effect.
