Abstract
The utility model discloses a radiator for a large-power electronic device, and the radiator comprises a bottom plate, and a plurality of cooling fins fixed on the bottom plate. A panel, which is connected with the cooling fins, of the bottom plate is plane. The cooling fins and the bottom plate are welded together. The cooling fins are fixed on the bottom plate in a manner of fin units. Each fin unit is a sheet material with a cross section in the shape of the Chinese character Ri. According to the utility model, the cooling fins are tightly connected with the bottom plate, and the radiator is lower in thermal resistance, thereby contributing to the improvement of cooling efficiency. Moreover, the machining is simple, thereby remarkably reducing the cost.
Description
Technical field
The utility model relates to a kind of radiator, is specifically related to a kind of high-power electronic device radiator.
Background technology
On various electronic devices, usually need to arrange radiator, particularly powerful electronic device, the setting of radiator is extremely important especially.The high-power electronic device radiator of prior art is generally that fin (fin is also referred to as fin) is set on the base plate of radiator.For example, Chinese 200920222446.3 utility model patents, are on base plate, to offer slot, and fin (being called " inserted sheet fin " in this utility model) is fixed in this slot.For another example: Chinese 201010147720.2 the utility model patent applications are on base plate, to offer inserted slot and rolling groove, inserted sheet riveted joint are installed in inserted slot.China's 200310106539.7 the utility model patent applications, are on base plate, alternately to offer mounting groove and indent, fin is installed in mounting groove and is impacted, and make mounting groove from the tight fin of two side direction therebetween.Above each scheme of prior art all need to be offered notch on base plate, and also needing of having press-fits or rivet, technique more complicated.Meanwhile, the junction of mechanical hard-wired fin and base plate, contact not exclusively, can form the interface that thermal resistance is larger, and hinders heat conduction, affects radiating effect.
Utility model content
The utility model, for the deficiencies in the prior art, proposes a kind of high-power electronic device radiator, and the fin of this high-power electronic device radiator is tight with being connected of base plate, has lower thermal resistance, is conducive to improve radiating effect.And processing is simple, can be significantly reduced to this.
In order to realize above-mentioned utility model object, the utility model provides following technical scheme:
A kind of high-power electronic device radiator, comprises base plate and is fixed on several fin on base plate,
The plate face that described base plate is connected with described fin is plane,
Described fin and described base plate weld together,
Described fin adopts the form of fin unit to be fixed on described base plate, and each fin unit is that a slice cross section is the sheet material of day font.
Further, described fin adopts the form of fin unit to be fixed on described base plate, and each fin unit is two sheet materials that cross section is day font that link together.
A kind of high-power electronic device radiator of the utility model, the fin of this high-power electronic device radiator is tight with being connected of base plate, has lower thermal resistance, is conducive to improve radiating effect.And processing is simple, can be significantly reduced to this.Fin is connected with base plate and is made production more convenient by the form of fin unit.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail, the description of this part is only exemplary and explanatory, should not have any restriction to protection range of the present utility model.
A kind of high-power electronic device radiator as Figure 1-5, comprises base plate and is fixed on several fin on base plate, the plate face that base plate 1 is connected with fin is plane, and fin and base plate 1 weld together.
Fin adopts the form of fin unit 2 to be fixed on base plate 1, and each fin unit 2 can be the sheet material of day font for a slice cross section, and the parallel placement of the sheet material bottom surface that can be also day font by two cross sections links together and forms.Every day font sheet material bottom surface comprise its both sides flank 21, flank 21 makes its bottom surface be wider than its end face, this design has ensured have certain distance to ensure radiating effect between two adjacent day font sheet materials, and has increased itself and the connection area guarantee stable connection of base plate 1.The cross section adopting in the present embodiment is that the sheet material of day font has 28, also can adopt 27 or still less, or 29 or more.
The utility model is in the time making, on the plate face being connected with fin at base plate 1, lay weld tabs 3, then fin unit 2 use fixtures are fixed on base plate 1, mode by vacuum brazing or Noclock soldering is welded on the bottom surface of fin unit 2 on base plate 1, finally fix the side guard plate 5 parallel with fin in base plate 1 both sides with screw 4, side guard plate 5 cross sections are zigzag towards heating panel one side.
A kind of high-power electronic device radiator of the utility model, the fin of this high-power electronic device radiator is tight with being connected of base plate, has lower thermal resistance, is conducive to improve radiating effect.And processing is simple, can be significantly reduced to this.Fin is connected with base plate and is made production more convenient by the form of fin unit.
Claims (2)
