Similar, its difference is that the heat conduction intermediate plate 100 ' of the present embodiment is without extension 140.Due to heat conduction intermediate plate
100 without extension 140, and the root edge from wind section 120 of heat conduction intermediate plate 100 and the second fin 300
Root edge trims and is collectively forming a continuous surface and comes and thermal source 10 thermally contacts, thus can promote further thermal source 10 with
Heat exchanger effectiveness between radiator 30.
First lateral margin 210 of the first fin 200 of first embodiment aligns the second side of the second fin 300
Edge 310, but be not limited thereto.Refer to Fig. 7.Fig. 7 is for according to described in third embodiment of the invention
The first fin and the partial side schematic diagram of the second fin.
In the present embodiment, these first fins 200 respectively have one first away from gas flow generator 20
Lateral margin 210.These second fins 300 respectively have one second lateral margin 310 of adjacent gas flow generator 20.
These first lateral margins 210 of these the first fins 200 are respectively adjacent in these of these the second fins 300
Second lateral margin 310, and sequence each other.
By the dislocation relation of these first fins 200 with these the second fins 300, first flow 32
Interior radiating airflow F can be divided into two and flow in 2 second adjacent runners 34, to expand heat transmission gas
The stream F heat dissipation region to radiator 30.
According to the radiator disclosed in above-described embodiment and heat abstractor, by the first fin being obliquely installed
With the guiding of the second fin, can force radiating airflow in first flow and the first fin sharp impacts, and
Force radiating airflow in the second runner with the second fin sharp impacts.Consequently, it is possible to get final product heat radiation
Heat exchanger effectiveness between air-flow and radiator, and then the heat dissipation of heat radiation device and radiator.
