Abstract
The utility model relates to a radiator with thinner fins which comprises a base and a plurality of fins. The base is provided with a plurality of grooves separated with intervals. The edges of the fins is locally folded to form bend parts which is overlapped on the surface of the fins to increase the thickness. The fins are fixed in the grooves relative to the base via the local edges and bend parts, thereby forming a radiator with thinner fins, increased density and higher heat emission efficiency. The width of the grooves on the base is enlarged to simplify the process and reduce the manufacturing cost.

Yet fin 92 is made into thin thickness, and also essential corresponding the narrowing down of the width of each groove 911 of pedestal 91, but narrower groove 911 processing are difficult for, and can increase the degree of difficulty of making makes the cost of manufacture increase.
Be with, as from the foregoing, above-mentioned known heat abstractor on reality is used, obviously has inconvenience and exists with defective, and can wait to be improved.
Summary of the invention
Main purpose of the present utility model is to provide a kind of heat abstractor that has than thin ribs, fin can be made thin thickness, and the density that makes fin be provided with increases, and makes heat abstractor have big area of dissipation, thereby makes radiating efficiency effectively improve; The utility model is bent to form invayination with the fin part, make the fin local edge form thicker thickness, so each groove of this pedestal can be made into the width of corresponding broad, makes groove processing easy, can reduce the degree of difficulty that groove is made, cost of manufacture is reduced.
In order to achieve the above object, the utility model provides a kind of heat abstractor that has than thin ribs, comprising: a pedestal, and it is provided with the groove that a plurality of intervals are provided with; And a plurality of fins, its local edge has been bent to form invayination, and this invayination is stacked and placed on the fin surface, makes the fin local edge form the thickness thick than fin, and described fin is ccontaining and be fixed in the groove of this pedestal correspondence with local edge and invayination.
According to the heat abstractor that has than thin ribs of the present utility model, wherein this invayination is located at this fin lower edge.
According to the heat abstractor that has than thin ribs of the present utility model, wherein this pedestal is made with copper material or aluminium.
According to the heat abstractor that has than thin ribs of the present utility model, wherein this pedestal comprises a central sections, and extends the wing panel from these central sections two respective side respectively, being arranged on this central sections and the wing panel of described groove equi-spaced apart.
According to the heat abstractor that has than thin ribs of the present utility model, wherein said fin is made with copper material or aluminium.
According to the heat abstractor that has than thin ribs of the present utility model, wherein this pedestal is softening through heat treatment, and with external force from the average application of force of these pedestal two respective side, make each groove distortion clamp described fin local edge and invayination.
Of the present utility model have than the heat abstractor of thin ribs by fin being made thin thickness, and the density that makes fin be provided with increases, and makes heat abstractor have big area of dissipation, thereby makes radiating efficiency effectively improve; And, make the fin local edge form thicker thickness by the fin part is bent to form invayination, so each groove of this pedestal can be made into the width of corresponding broad, makes groove processing easy, can reduce the degree of difficulty that groove is made, and cost of manufacture is reduced.
In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet accompanying drawing only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.
