Fin can have various ways, can be set to semiellipse as indentation, there, semicircle, and triangle, trapezoidal and rectangle etc., fin can vertically mutually also can form certain acute angle with the flow direction of contact position fluid in addition.
Working medium can be water, and in view of the highest tolerable temperature of CPU is 60 ℃, so channel inner pressure should be less than 0.2 atmospheric pressure.
Operation principle of the present invention is as follows: this mixed small-channel cooler is positioned on the electronic product, the heat that electronic product discharges passes to working medium through the matrix of high-termal conductivity, because of channel inner pressure lower, all working medium progressively become gaseous state by liquid state, the working medium of gaseous state flows to the interconnection A place of passage along unidirectional valve I, and continue to flow, form the closed-loop path of a matrix-unidirectional valve I-unidirectional valve III-unidirectional valve IV-unidirectional valve II-matrix.Gas is when flowing into interconnection A place, contact with the liquid phase that flows out from unidirectional valve IV, make gas temperature reduce, portion gas is converted into liquid, heat radiation through fin when unconverted part for liquid arrives interconnection B is converted into liquid, thereby realize the dual cooling of gas, improved cooling effect.
The present invention has following technique effect and advantage:
1) mixed small-channel cooler that the present invention relates to, be arranged on the electronic product, make working medium can realize " self-loopa ", the heat drive liquid that relies on electronic product to distribute produces phase transformation, and relies on mixed heat transfer and heat convection dual mode to realize the phase-change heat of gas to liquid.The good heat dissipation effect of this radiating mode, compact conformation, cost are low, and noiselessness simple in structure.
2) adopt mixed small-channel to dispel the heat, strengthened radiating effect greatly, be applicable to the high integration electronic product and the demanding occasion of dispelling the heat.
3) the closed loop durability of Xing Chenging is good, generally need not maintenance.
Mixed small-channel cooler of the present invention can be used for following field:
1) computer chip heat radiation
2) large power, electrically sub-element such as transistor, the heat radiation of large scale integrated circuit
3) heat radiation of space craft heater element.
