embodiment:
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
With reference to Fig. 1, Fig. 2, the notebook drawing-in type heating radiator that a kind of 5V, 12V voltage is general, comprises housing, is installed on the backing plate 6 of housing forward end, is installed on fan blower 3 in housing and pcb board 4, it is characterized in that:
Described housing comprises face-piece 1 and drain pan 2;
Described face-piece 1 upper front is provided with acrylic panel 7, and face-piece 1 front end is provided with inlet scoop 102, and face-piece 1 rear end is provided with exhaust outlet 101 and DC power interface 403;
