Background technology
Along with development of science and technology, increasing power electronic element power is increasing, and the problem of thereupon bringing is that the caloric value of these elements is increasing, and the high temperature that caloric value produces can cause the circuit elements design life-span to be reduced, system's operation is unstable, can burn out key element when serious.
In order to take away the high density heat that produces when these elements are worked, extensively adopt the mode of water-cooling at present, in existing water cooling technology, the general water-filled radiator that adopts tubular type, copper pipe formula or perforating type water-filled radiator, or the water-filled radiator of welding alternating expression fin, the water-filled radiator of first kind of structure is because cooling water contact area and heat exchange coefficient cause heat exchange efficiency low for a short time, heat can not fully be pulled away, but internal pressure drops is little, and is little along the journey water resistance.Water-filled radiator cooling water contact area and the heat exchange coefficient of second kind of structure are enough, but inner excessive along the journey water resistance, pressure drop is excessive, causes heat not taken away fast.
The utility model content
Utility model purpose of the present utility model is by having adopted a kind of perforated fin, improved heat exchange effect and heat exchange efficiency height, fully having taken away heat fast.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of water-filled radiator that contains perforated fin is provided, comprise substrate, perforated fin and cover plate, the upper surface of described substrate is provided with conduit, described perforated fin is fixed in the conduit, and described cover plate is fixed on the substrate to cover described conduit, and described substrate is provided with the intake-outlet that is communicated with conduit, described perforated fin is plain fin, and staggered hole is arranged above.
In preferred embodiment of the utility model, described staggered hole is circular port or polygonal hole.
In preferred embodiment of the utility model, the degree of depth of described conduit is identical with the height of described perforated fin or inequality.
In preferred embodiment of the utility model, the middle part of described substrate is provided with boss, and described boss is located at the centre of described conduit, and described conduit is U-shaped.
In preferred embodiment of the utility model, described perforated fin is distributed in the boss both sides.
In preferred embodiment of the utility model, described substrate is provided with conduit, and described conduit is yi word pattern.
In preferred embodiment of the utility model, all connect by soldering between described substrate, perforated fin and the cover plate.
In preferred embodiment of the utility model, described substrate, perforated fin and cover plate are copper, copper alloy, aluminum or aluminum alloy.
The beneficial effects of the utility model are: heat exchanger heat exchange efficiency height of the present utility model, and inner water resistance is little simultaneously, and pressure drop is little, can fully take away heat fast.
