Description
Technical field
The utility model relates to a kind of heat abstractor, relates in particular to a kind of water-cooling heat radiating device with working fluid.
Background technology
Increasing along with electronic building brick and included semiconductor desired power thereof, cause the electricity consumption density of related system to be increased sharply, the related caloric value that also causes the electric power control assembly greatly increases.Particularly in main frame inside, because the operation efficiency of main frame improves constantly, the electronic building brick of periphery also is on the increase simultaneously, makes the whole caloric value of computer also significantly promote thereupon.Therefore, in order to reduce the too high temperature that electronic building brick produces, so that the working temperature of main frame inside keeps stable, radiating mode becomes an important step of development in science and technology now undoubtedly.
For now, the known heat dissipation technology of people is exactly a fan the most.Because fan has the function that produces forced draft, by the drive of forced draft, will attract the air of thermal source to take away arround the electronic building brick.Under air-flow constantly circulates, carry out air-cooled heat radiation.Yet fan needs the bigger space that is installed with, and air-cooled thermolysis more and more is unable to catch up with the generation of heat, makes radiating effect have a greatly reduced quality.
In order to remedy the deficiency of ventilation type thermolysis, the known another kind of practice is to adopt water-cooled power converter.Because adopt the working fluid heat radiation to have higher heat transfer efficiency, the water-cooled head that will have the working fluid circulation directly is attached on the electronic building brick, make this working fluid directly and apace produce heat exchange action with electronic building brick.The working fluid that has suctioned thermal source afterwards then passes through the heat radiation row who is communicated with again and carries out the air cooling heat radiation, thereby is so constantly dispelling the heat under the working fluid cycles.
Though water-cooled thermolysis can obtain better radiating effect, but water-cooled radiator structure still has some shortcomings: because water-cooled radiating efficiency depends on the heat exchanger effectiveness that working fluid and heat radiation are arranged, inhaled the working fluid that thermal source is arranged and carried out heat exchange action with heat radiation row, make thermal source reach heat radiation row externally dissipation again, but existing heat radiation row structure often flows too fast because of working fluid, with heat radiation row deficiency time of contact, when causing working fluid cycles to get back to water-cooled, can't proceed heat exchange again, directly have influence on whole radiating efficiency.And follow-up known technology is provided with circuitous runner in order to solve foregoing problems in heat radiation row inside, to slow down the speed that working fluid flows.Though this scheme can be improved the flowing velocity of working fluid, increase working fluid and the time of contact of dispelling the heat and arranging, help working fluid and carry out heat exchange action with heat radiation row structure, but still be subject to working fluid and the contact area of dispelling the heat and arranging, still can't carry out heat biography effect between the two fast, a fly in the ointment is still arranged.
