Description
Technical field
The present invention relates to a kind of bionical soaking plate liquid sucting core structure, effectively overcome the defect that the existing soaking plate liquid-sucking core technology such as flow resistance is large, transmission is slow, the blocking of microchannel, local, uniform temperature is low, intensity is low exist, electronic device local heat dissipation problem can be solved efficiently.
Background technology
Along with the development of electronic technology, circuit integration technique constantly promotes electronic product precise treatment day by day.Meanwhile, highly integrated electronic device causes the sharply increase of heat flow density, and heat radiation has become bottleneck problem impassable in electronic technology development.Soaking plate has been widely used in the middle of electronic equipment dissipating heat as the efficient heat transfer unit (HTU) of one.Liquid-sucking core, as the core texture of soaking plate, plays vital effect to the heat transfer property of soaking plate.
Because soaking plate have employed the mode of face heat transfer, compared to traditional heat pipe heat radiation, efficiency is higher, in the middle of the heat radiation being widely used in electronic device.Soaking plate is compared with traditional heat pipe, and operation principle is identical.It mainly contains evaporation ends, condensation end, liquid-sucking core, working medium composition.Its operation principle is: electronic device transfers heat to soaking plate evaporation ends substrate, and substrate transfers heat to working medium again, working medium be heated after evaporation, and arrive condensation end condense into liquid release heat.Liquid refrigerant is back to evaporation ends and forms a circulation under the effect of liquid-sucking core capillary pressure, so repeatedly.In order to make working medium can produce condensation at a lower temperature, so need in soaking plate to vacuumize.
Liquid-sucking core, as soaking plate essential elements, develops into various forms.Its structure mainly comprises sintered porous type, groove-shaped, screen mesh type and fibrous type liquid sucting core structure.Groove-shaped liquid-sucking core has very large permeability, but capillary attraction is minimum; Sintered porous type is just contrary with groove-shaped liquid-sucking core performance; Silk screen and fibrous type liquid-sucking core are between the two, but take relatively large space.
The heat transfer property of soaking plate depends primarily on liquid sucting core structure, and the permeability of liquid-sucking core and capillary attraction are the relations of conflict.Meanwhile, the electronic equipment day by day become more meticulous requires more and more harsh to the bulk of soaking plate.Simultaneously, soaking plate due to short transverse thickness less, and along with the development of electronic technology, require that soaking plate is more and more thinner, therefore the wall shell of soaking plate can become thinner with the volume increasing soaking plate cavity, but this can cause soaking plate intensity to reduce, soaking plate can be caused after evacuation to be out of shape or to produce and subside.Therefore in order to gain in strength, in soaking plate, add support column, but the increase of support column greatly can reduce disengagement area, the change of soaking plate chamber flow field can be caused simultaneously, be unfavorable for the raising of radiating efficiency.
Plant leaf blade is evolved through the development of 1 years, and the working medium having defined a kind of optimization transports system.Research finds that the formed symmetrical structure of plant leaf vein has the shortest transportation route.Have based on plant leaf vein polygon fractal structure and prevent vein from blocking or rupture and destructive infringement is caused to plant leaf blade.Nutriment can be transported to fast each position of plant leaf blade from point based on the vein of plant leaf blade and mesophyll tissue's structure, this institutional framework has the shortest transportation route.
Inspire by this, the invention provides a kind of based on the bionical soaking plate liquid-sucking core of plant leaf blade institutional framework.This liquid-sucking core has taken into full account that present stage has the deficiency of soaking plate technology existence, and has drawn plant leaf blade High-efficiency Conveyance System structure, devises a kind of novel bionical soaking plate liquid sucting core structure.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide that a kind of capillary pressure is large, flow resistance is little, uniform temperature is good, heat dispersion is high, avoid local to occur the liquid sucting core structure of the Novel imitation plant leaf blade Optimizing Transport structure of dry and blocking.
The present invention is achieved through the following technical solutions:
A kind of bionical soaking plate liquid-sucking core, comprise the central condensing zone for holding liquid refrigerant, main transport channel, support column, interface channel, annular flange flange, condensation substrate, micro-channel, described condensation substrate is provided with land area, in the middle part of the described central condensing zone land area being arranged at condensation substrate in the form of slot, this central condensing zone forms liquid storage pool, collects condensed liquid refrigerant and transports in main transport channel.
