According to the design, the coolant which is located in the storage seat can be suspended by the passive pump and transmitted to the conduit to prolong a flowing path, the conduit and the fins are crossed and contacted to increase the heat dissipation efficiency, and thereby the temperature of the coolant does not rapidly increase easily, which can effectively increase the whole heat dissipation efficiency.
Description
Technical field
The present invention relates to a kind of heat abstractor, particularly relate to the liquid-cooling heat radiator that a kind of heat that is used for that electronic component is produced is got rid of heat radiation rapidly.
Background technology
Along with scientific and technological progress, many electronic components marched toward all miniaturization, design characteristics such as high-speed, the central processing unit in the computer product (CPU) especially, characteristics attract the consumer to buy to upgrade faster especially.The height but the CPU of high-speed computation more, the heat of generation also can be healed, if can't be in real time promptly with the heat band from CPU, tend to cause problems such as computer corruption, data damage, therefore, how handling the electronic component heat dissipation problem in when operation, is that the dealer constantly makes great efforts the direction studied.
Consult Fig. 1, it is general eddy current type heat abstractor 1, but heat exchange ground is connected with electronic component 2, the hot type that produces during with these electronic component 2 operations itself moves to keep this electronic component 2 normally from this electronic component 2 itself.This eddy current type heat abstractor 1 comprises a heat-dissipating casing 11, an active fans 12, and a passive pump 13.
This heat-dissipating casing 11 has one and stores seat 111 with this electronic component 2 carries out heat exchange, and multi-disc stores seat 111 outward extending fins 112 by this, and this stores seat 111 inside and is hollow form and stores cooling fluid 113 is arranged.This active fans 12 has stretched through a rotationally rotating shaft 122, of this fan shell 121 of the fan shell 121, of seat on 111 that stores that is installed on this heat-dissipating casing 11 and is connected with power rotor 123 in this rotating shaft 122, reaches one and is arranged in this rotating shaft 122 and between this fan shell 121 and store first magnetic conductive part 124 between 111.This passive pump 13 has the axles 131, of seat in 111 that store that are hubbed at this heat-dissipating casing 11 and is connected with passive rotor 132 in this axle 131, and one is arranged in this axle 131 and produces second magnetic conductive part 133 of magnetic interactions with this first magnetic conductive part 124.The heat energy that this electronic component 2 is produced just can conduct to this and store seat 111, fin 112, and this stores the cooling fluid 113 in the seat 111.
This eddy current type heat abstractor 1 is when actual motion, at first activate this active fans 12 so that its power rotor 123 rotates, relending also can be in company with rotation by first magnetic conductive part 124 that is arranged in this rotating shaft 122, its magnetic force meeting break-through is crossed this and is stored seat 111 and attract second magnetic conductive part 133 of this passive pump 13 of drive to rotate synchronously, and then make the axle 131 of this passive pump 13 and passive rotor 132 produce rotation, at this moment, be positioned at this cooling fluid 113 that stores seat 111 inside and just can be rotated and raise and form convection current by this passive rotor 132, whereby rapidly with the transfer of heat energy of this electronic component 2 to described fin 112.And the power rotor 123 that relends by this active fans 12 rotates, and the heat energy of described fin 112 is arranged discrete heat fast to ambient air, so that this electronic component 2 can move at lower temperature, promotes resistance to overturning.
Yet, cooling fluid 113 can only merely store the medial surface of seat 111 by this, and with thermal energy conduction to described fin 112, its heat conduction contact area can't effectively increase, the high heat that produces during with respect to these electronic component 2 operations, the radiating efficiency of this eddy current type heat abstractor 1 is difficult for satisfying the heat of dealing with this electronic component 2 and produces speed, the easy fast rise of the temperature of cooling fluid 113, cause this electronic component 2 to crash because of overheated often, even produce damage.
Summary of the invention
