[background technology]
With regard to the application of heat-exchange device, large-scale for example air conditioner, refrigerator, air conditioner or vehicle etc. are its indispensable device to small-sized demonstration integrated circuit (IC) chip or power supply unit or the like as the central processing unit integrated circuit (IC) chip in information products, north bridge integrated circuit (IC) chip, display card.
As being example in order to the cooling application of keeping chip operation temperature such as central processing unit, the heat exchange pattern major part of its heat-exchange device is to utilize as heat carrier that solid materials such as copper or aluminium are made contacts heat source body just like central processing unit chip etc., and on heat carrier, be provided with most outstanding radiating fins, by contacting of heat carrier and heat source body, make the heat transferred of heat source body to heat carrier, utilize the radiating fin on the heat carrier to contact with air again to carry out heat exchange, therefore the temperature of heat carrier can be reduced, and then the temperature of heat source body is and then reduced, to reach the purpose of heat source body heat radiation.And according to the principle of " chill effect ", i.e. every increase by 100 meter per seconds of the wind speed of a body surface, this object surfaces temperature can reduce by 1 ℃, therefore in order to promote the efficient of heat radiation, general way can be provided with a fan again and flow to force blow air, increase the speed that contacts between air and radiating fin surface whereby, and the wind speed that is produced is faster, its relatively efficient of heat radiation also can increase.
In addition, heat abstractor on some large scale systems also adopts the mode of carrying out heat exchange with air to dispel the heat mostly, but different places is being to adopt water as heat-conducting medium as water-cooled power converter, the oil injection type heat abstractor then adopts oil as heat-conducting medium, other has such as refrigerating air-conditioning is to adopt cold coal as heat-conducting medium, but no matter adopt which kind of material as heat-conducting medium, all can be provided with laminar radiating fin textural, and flow and carry out heat exchange to reach the purpose of heat radiation with these radiating fins by a fan blow air, difference therebetween is only in the problem of spent cost number.
