Description
Technical field
The present invention relates to a kind of bionic power drive type radiator, particularly a kind of driving systemic blood that imitates cardiac structure flows to realize the bionic power drive type radiator of heat to the imitative cardiac structure of flow transmission.
Background technology
In recent years, computer, microelectronics, photoelectric chip etc. are towards improving integrated level, reduce size and increase the trend development of clock frequency always, and therefore " thermal boundary " problem day shows severe.Calculate according to famous " Moore's Law ": the transistor on the computer chip doubled in per 18 months, and so by 2010, transistorized quantity will break through 1,000,000,000 on the chip, and at this moment, chip power consumption and heat dissipation problem also show especially out.The excessive temperature that brings thus will reduce the job stability of chip, increase error rate, and formed thermal stress can directly have influence on electrical property, operating frequency, mechanical strength and the reliability of chip between while inside modules and its external environment condition.In fact, not only for computer chip, for a large amount of power electronics devices, photoelectric device and development in recent years little rapidly/naiio-electro-meclianical systems etc., all exist similarly extensive and urgent heat radiation cooling needs, under the situation about having in addition requirement higher.Above situation shows, at present the demand of high-performance heat dissipation technology has been mentioned unprecedented aspect, and correlative study is the key subjects of common forward position of a plurality of ambits and concern.
The computer chip technology development is to the broad space of an urgent demand and the practical application of high-performance heat dissipating method, and feasible heat dissipation technology research to excessive heat current density opto chip, micro-system becomes important unusually in the world and the active research field.The chip radiator of selling on the market mainly contains air radiator, liquid radiator, heat-pipe radiator, refrigerant cooler, peltier cooler at present.First three kind is to utilize various heat-conducting mediums that heat is transmitted to the temperature that cold junction reduces chip from the hot junction, and back two kinds then is to rely on the cold that initiatively produces to reach the purpose that reduces chip temperature.Air radiator is because the thermal transmission coefficient of air is lower, though be used in combination many high thermal conductivity materials such as aluminium, copper even silver etc. and used mode such as fin, the fan etc. of various enhance heat transfer, but the thermal transmission coefficient of this class radiator is tending towards its physics limit substantially at present, and it is bigger further to promote the cost that performance need pays.And along with the raising of fan speed, the noise of generation also constantly increases, and in the face of the chip heat generation density that day by day increases, these class methods can not finely adapt to.But, because its price is comparatively cheap, therefore still be a kind of commonplace radiating mode in actual applications.The thermal transmission coefficient of heat-pipe radiator is very high, but manufacture craft, encapsulation condition are had relatively high expectations, along with development of technology, price begins progressively to descend, but still pace up and down outside the threshold of widely applying, and when the chip heat generation density was too high, all evaporation was dried can to cause inside heat pipe liquid, thereby working medium is difficult to finish normal circulation to be transported, and can cause that burning phenomenon takes place.Refrigerant cooler and peltier cooler make their application in the chip cooling of high heating power have inborn advantage owing to possess the mode of active refrigeration, but complex manufacturing technology, and cost is high relatively, less seeing on the market.
In comparison, liquid cooling heat radiator is the better combination that takes into account heat transfer efficiency and production cost.The thermal conductivity of liquid particularly convective heat transfer speed and specific heat capacity is that air can't be reached, and fluid working substance can utilize the liquid of some less expensive, as water, alcohol etc., manufacturing process does not have heat-pipe radiator, refrigerant cooler and peltier cooler requirement height yet.Can predict, in one long from now on period, liquid cooling heat radiator may become the main flow in market.Liquid cooling heat radiator mainly is made up of heat-absorbing model, radiating module, fluid pump, fluid working substance etc., its basic functional principle is: outside heat load is added on heat-absorbing model, the working medium temperature rises, and is transferred to radiating module subsequently under the driving of pump, and heat is dispersed in the air from working medium.Like this, working medium constantly circulates in heat pipe, and heat is transported away constantly.
Yet the liquid cooling system of selling on the market mostly is that fluid driven pumps separates with refrigerating module at present, has increased the volume of cooling system like this, has increased the resistance and the power consumption that flow, and the installation process more complicated.Just because of this, for a long time, the driving pump in liquid cools conducts a research, and how to improve driving efficient is the significant effort direction of engineers always.From bionic angle, heart is as the unique actuating force source of blood of human body, and its small and exquisite volume but can provide the continuous driving force that is enough to overcome complicated blood vessel network flow resistance in the human body, new thinking is provided for the design of fluid driven pumps.Just be based on this consideration, the invention provides a kind of new liquid cooling heat radiator scheme, can the more diversified radiator of way of realization.
