Description

The radiator structure of heat abstractor

Technical field

The utility model relates to a kind of radiator structure of heat abstractor, refers to a kind of radiator structure that promotes the heat abstractor of heat sink interior working fluid vapour-liquid cycle efficieny especially.

Background technology

Existing electronic equipment internal selects thermal transmission elements such as heat pipe, temperature-uniforming plate, loop circuit heat pipe, heat exchanger to carry out heat conduction work for stressing high cooling efficiency in a large number.

And its pyroconductivity of these thermal transmission elements is about several times to tens times of metals such as copper, aluminium and therefore suitable excellence is that quilt is applied to various hot countermeasure correlation machines with element as cooling.From shape, heat pipe can be divided into the heat pipe of heat pipe, flat pattern and the D type shape of round tube shape.In order to cool off CPU or other because of carrying out the part to be cooled of e-machine that computing or work produce the electronic component etc. of heat; In part to be cooled and can obtain the viewpoint of broad contact area, also adopt temperature-uniforming plate or platypelloid type heat pipe or slim heat exchanger to dispel the heat based on easy mounting.Along with miniaturization, the save spaceization of cooling body,, necessity of the utmost point slimming of being strict with this heat pipe is arranged more in the situation of the cooling body that uses heat pipe.

Said these thermal transmission element internal work fluids desire to carry out the vapour-liquid circulation time; Its inner capillary structure (groove, metal grill body structure, sintering structure etc.) that needs setting to have capillary force makes to make working fluid be able to carry out in this thermal transmission element smoothly the work of vapour-liquid circulation.

If these thermal transmission elements need be used in comparatively narrow part, then certainly will process slimming, capillary structure that should inside then will be except the thickness problem of thermal transmission element own, makes this thermal transmission element can't process the main problem of slimming.

Moreover the capillary structure of processing after the slimming then can be because of its capillary force after the slimming also descends, influence within this thermal transmission element working fluid vapour-liquid cycle efficieny and then make heat conduction efficiency significantly reduce, so known techniques has disadvantage:

1, hot transfer efficiency is not good;

2, the thermal transmission element slimming is limited.

The utility model content

Therefore, for effectively solving the above problems, the main purpose system of the utility model provides a kind of radiator structure that promotes the heat abstractor of heat conduction and radiating efficiency.

Another purpose of the utility model system provides a kind of radiator structure of heat abstractor of its internal work fluid vapour-liquid circulation of heat abstractor that promotes slimming.

For reaching above-mentioned purpose; The utility model system provides the radiator structure of a heat abstractor; System comprises: a heat abstractor body has a chamber, and said chamber is provided with an at least one palpus crystal structure layer and a working fluid, and brilliant (Whisker) structure sheaf of this palpus extends is located at this chamber inner wall.

It is wherein arbitrary that said heat abstractor body series can be heat pipe and loop circuit heat pipe and flat plate heat tube and temperature-uniforming plate and heat exchanger.

Said palpus crystal structure series of strata can significantly promote the efficient of the vapour-liquid circulation of this heat abstractor body interior working fluid; And because of its structure careful; Still can keep its capillary force when making this heat abstractor slimming, make the smooth vapour-liquid circulation of heat abstractor body interior working fluid.
