Description
Technical field
What the present invention relates to is a kind of refrigeration system, specifically is a kind of liquid-circulating refrigeration system for computer heat radiation.Be used for refrigeration technology field.
Background technology
Increase along with the energy of the raising of the integrated degree of computer and the increase of system capacity, especially CPU.The heat management of the computer system that makes is faced with increasing challenge.According to the prediction of " international semiconductor guide " magazine, the maximum heat dissipation capacity of single chip board will reach 170w in the time of 2008; Reliability and the life cycle of while in order to improve electronic equipment, the maximum contact temperature of permission will be controlled at below 85 degree.Because the restriction of the hot rerum natura of working fluid itself, this is difficult to reach concerning the passive type cooling technology.So adopting active cooling means may be effective solution, wherein a kind of is exactly to adopt refrigeration system.Because the restriction in space in the computer system of reality, refrigeration system should have much the same size with chip or printed circuit board (PCB).
Find through literature search prior art, Bernd Gromoll is at " Revue G é n é rale deThermique " Volume 37, Issue 9, October 1998, " the Microcooling systems for high density packaging " that delivers on the Pages 781-787 (is applied to the micro cooling system of high density assembling, the technology general survey, the 37th volume, proposition 9, in October, 1998, the 781-787 page or leaf) propose in: by miniature thermal siphon, miniature evaporator and miniature fin condenser are formed cooling system.Evaporator links to each other with thermal source, and heat is delivered to condenser by the evaporation and the condensation of cold-producing medium (water or FC72), and condenser is dispersed into heat in the environment by the forced convertion with surrounding air and goes.The position of condenser must be above evaporator in addition, and its heat flux can reach 30Wcm
-2Along with the raising of electronic system integrated level and the increase of heat dissipation capacity, its heat dissipation capacity eventually can not meet the demands.In the application of reality, be difficult to guarantee that condenser one fixes on the top of evaporator (as when using notebook computer) simultaneously.
Summary of the invention
The present invention is directed to the deficiencies in the prior art and defective, a kind of liquid-circulating refrigeration system for computer heat radiation is provided, make it adopt a kind of new refrigeration cycle, can satisfy the heat radiation requirement of computer system.
The present invention is achieved by the following technical solutions, the present invention includes: micropump, evaporator, gas-liquid separator, condenser, fan and a T-valve.Their annexations are: micropump links to each other by the inlet of pipeline and evaporator, and the outlet of evaporator and the import of gas-liquid separator link together; Gas-liquid separator has two outlets, liquid after the separation is connected to T-valve import A by the outlet of lower end, gaseous state condensing agent after the separation flows into the condenser from the outlet of upper end, condenser is forced cooling by fan, the outlet of condenser is connected to T-valve import B, and the outlet C of T-valve is connected to micropump by pipeline.Fan is fixed on directly over the condenser by clip.Each parts closes along the position of gravity direction: evaporator, and gas-liquid separator and condenser are positioned at the top of system, and micropump and T-valve are positioned at system bottom, and evaporator 4 and T-valve 6 are positioned at the centre position.
The power that the present invention is provided by micropump overcomes friction and the action of gravity equal loss in the circulation system.Because the whole circulation system size is less, change through the fluid pressure behind the micropump little, little to the influence of its thermal behavior, so total system can be supposed to carry out waiting to depress.Liquid coolant after micropump is pumped, in the inflow evaporator, behind the heat of absorption thermal source, the part liquid coolant flashes to gaseous state; The cooling medium of gaseous state flows in the gas-liquid separator under the promotion of vapor pressure, cooling medium after the partial condensation flows into T-valve under the effect of gravity, the cooling medium of gaseous state flows in the condenser under the promotion of vapor pressure, condenser adopts the fin-tube type structure, force cooling by the fan blow air, the cooling medium behind condenser flows into T-valve; The cooling medium that flows into T-valve is sucked by micropump again, has so just finished the whole circulation process.
The invention solves the deficiencies in the prior art, can satisfy the heat radiation requirement of computer system.Since adopt indirect liquid cooling mode, by regulating the flow of micropump, can be so that the heat dissipation capacity of total system reaches very big value.In addition by selecting for use suitable low-boiling liquid coolant just the temperature of evaporator section can be controlled at than low spot, the temperature that is about to thermal source such as electronic product etc. is controlled at than low spot, and higher temperature will influence the performance of electronic product, will help improving its performance on the lower temperature spot so be controlled at by the temperature with electronic product.
