Description

The heat conducting heat-exchange device of circulation channel formula

(1) technical field

The utility model relates to a kind of heat-exchange device, particularly relates to a kind of heat conducting heat-exchange device of circulation channel formula that can transmit heat rapidly.

(2) background technology

As shown in Figure 1, general heat-exchange device 1, comprise and one have the heat radiator body 11 of an inner cavity chamber 111, be sealed in a top cover 12 and a base 13 of the inner cavity chamber 111 of this heat radiator body 11 respectively, and be poured in the working fluid 15 of the inner cavity chamber 111 of this heat radiator body 11 through a filling pipe 14; This base 13 is to be sticked at a thermal source 2 end faces, and this thermal source 2 can be a central processing unit (CPU), integrated circuit (IC) chip (IC), module ... Deng, borrow this base 13 to be sticked on this thermal source 2, can be with the main thermal source up conduction rapidly of this thermal source 2.

During use, because of the heat dissipation of this heat-exchange device 1 is that the temperature of utilizing a thermal source 2 rises after when integrated circuit work (such as), excite the working fluid 15 that is positioned at this heat radiator body 11, make this working fluid 15 absorb heat gradually, in after after a while, this working fluid 15 can form vaporization and be converted to gaseous state, the working fluid 15 of having vaporized can carry out heat exchange with the outside air convection of this heat radiator body 11 and reach condensation, make the working fluid 15 of gaseous state shape be converted to liquid state again, and then reach heat absorption, the circulation radiating effect of heat radiation, the last cooling surface area that also passes through the radiating fin 112 of this heat radiator body 11 is evacuated waste heat.

But in the reality, when this working fluid 15 is excited by the intensification of thermal source 2, the straight diapire 131 of this base 13 disperses and to assemble because of can make the energy of the superincumbent working fluid 15 that distributes, promptly, though the liquid heat absorption is faster than solid, but the slow straight diapire 131 that absorbs heat be fitted in earlier carry out heat exchange on the thermal source 2 after, pass to the fast working fluid 15 of heat absorption again and carry out heat exchange, cause exciting the time of working fluid 15 to be elongated, add that 1 limited cooling surface area by this radiating fin 112 of this general heat-exchange device carries out heat exchange action, cause eventually and heat energy can't be transferred out fast, wait to make great efforts the improved target of research for relevant dealer's utmost point really.

(3) utility model content

The purpose of this utility model is that a kind of heat conducting heat-exchange device of circulation channel formula that can transmit heat rapidly is being provided.
