Abstract

The utility model relates to a radiator with large area. A plurality of heat radiating fins are arranged on a heat radiating plate; paths for airflow are formed among the heat radiating fins. The heat radiating fins on one side of the heat radiating plate are formed lower; the space above the heat radiating plate can be used for combining a baseplate. Holes are arranged on the baseplate corresponding to the lower heat radiating fins in the space above the lower heat radiating fins. Rods are arranged around each of the hole; a seat plate is supported by the other end of each of the rods; a fan wheel is pivoted to the seat plate, and the fan wheel rotates around the seat plate. The baseplate is provided with side walls which are extended downward; the end surfaces and both sides of the lower heat radiating fins are enclosed by the side walls.

Description

Has the larger area heating radiator

The utility model relates to a kind of larger area heating radiator that has.

In the 29608 No. two " CPU seat and cooling mechanism unitized construction " patent case announced in Taiwan, disclose a kind of small-sized central processing unit, amplexiformed heat sink on it, establish a radiator fan by heat sink, the heat that central processing unit is produced can be dispelled the heat fast, because this kind heat sink has than small size, therefore, it only is suitable for having the central processing unit than small size, when central processing unit has than large tracts of land, just need to be combined on the central processing unit, so with plural heat sink, it needs double cost, and also pretty troublesome in combination.

The purpose of this utility model is to provide a kind of larger area heating radiator that has, and it has gone for the larger area central processing unit, in order to central processing unit heat radiation, and lower cost is arranged.

The purpose of this utility model is achieved in that promptly provides a kind of larger area heating radiator that has, and it comprises: heat sink, if several radiating fins, between each radiating fin gas channel is arranged, the radiating fin of a side has shorter height, and described heat sink is provided with several engagement grooves; Substrate is bonded to the sky of described radiating fin, and it is establishing the hole with respect to the shorter radiating fin sky, and several bars are established by periphery in described hole, and the described bar other end is supported a seat board, and described seat board articulates rotation for impeller; Described substrate is provided with the sidewall of downward extension, and described sidewall is with the end face and the dual side-edge sealing of the shorter radiating fin of heat sink.

The advantage of the utility model device is that area of dissipation is big, and good heat dissipation effect has been specially adapted to the larger area central processing unit.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:

Fig. 1 is an exploded perspective view of the present utility model;

Fig. 2 is a combination top view of the present utility model;

Fig. 3 is a 3-3 line sectional view among Fig. 2;

Fig. 4 is a 4-4 line sectional view among Fig. 2.

See also shown in Figure 1ly, the utility model includes main members such as heat sink 1, substrate 2.

This heat sink 1 is made by metal materials such as aluminium, it can form rectangle etc. than large tracts of land, the bottom becomes the plane can amplexiform on central processing unit, the radiating fin 11 of several settings is established at this heat sink 1 top, make heat sink 1 have bigger area of dissipation, form gas channel 12 between each radiating fin 11, heat sink 1 one sides form shorter radiating fin, overhead by this shorter radiating fin for impeller 25 movable rotations, flow along gas channel 12 to drive air, and towards another side discharge, heat sink 1 itself can be by 2 combinations of substrate, and radiating fin 11 crosscuts have engagement groove 13, and engagement groove 13 can be inserted by fastener, in order in conjunction with heat sink 1 and central processing unit.

This substrate 2 can be bonded on the heat sink 1 with various combinations, fixing with screw 14 as shown in the figure, this is a kind of more suitable method, one hole 21 is arranged on this substrate 2, it is comparatively suitable that hole 21 is positioned at shorter radiating fin 11 sky of heat sink 1, the periphery in hole 21 has extended several bars 22 downwards, bar 22 other ends can be supported a seat board 23, seat board 23 can articulate rotation for impeller 25, can be as shown in the figure, articulate with the central shaft of a central siphon 24 for impeller 25, for the rotation that makes impeller 25 has preferable air-supply effect, substrate 2 is provided with three sidewalls 26 that extend downwards, sidewall 26 is respectively with the end face and the dual side-edge sealing of the shorter radiating fin 11 of heat sink 1, therefore, driven the air-flow that send by the rotation of impeller 25 and can guarantee to drive and send, make heat sink 1 that best radiating effect be arranged towards heat sink 1 other end.

See also combination situations of the present utility model shown in Fig. 2 to 4, when substrate 2 with after heat sink 1 combines, the sidewall 26 of substrate 2 is respectively with the end face and the dual side-edge sealing of the shorter radiating fin 11 of heat sink 1, therefore, impeller 25 is limited in rotating in the space of 26 corrals of side plate, the air-flow that it drove can follow gas channel set between the radiating fin 11 12 and drive and send, and by the output of heat sink 1 other end, forms best radiating effect.

Heat sink of the present utility model can form than large tracts of land, therefore, can directly combine with plural small-sized central processing unit or a large-scale central processing unit, and because the good design and the arrangement of substrate, the air-flow that impeller drove can be fully utilized, the hot gas that radiating fin is distributed can effectively be excluded, to bring into play best radiating effect.
