Abstract
The utility model relates to a forward centrifugal direct-current fan which comprises a spiral casing, a forward centrifugal wind wheel, a direct-current fan circuit control board and a heat radiator, wherein the forward centrifugal wind wheel is fixed in the spiral casing. The forward centrifugal direct-current fan has characteristics that the heat radiator is a flat-board heat radiator which is fixed outside a side board of the spiral casing, a plurality of heat radiating holes are arranged on the side board and matched with the heat radiating board, and the direct-current fan circuit control board is arranged on the heat radiating board. The forward centrifugal direct-current fan has the advantages of simple structure, low production cost, good heat radiating effect and the like.
Description
Technical field
The utility model relates to the centrifugal dc fan of a kind of forward direction.
Background technique
At present, the centrifugal dc fan of the forward direction that uses on the market comprises volute casing (2), is fixed on forward-type centrifugal wind wheel (3), dc fan circuit control panel and radiator (1) in the volute casing, as shown in Figure 1.Its dc fan circuit control panel generally is mounted in motor internal, the radiator of dc fan circuit control panel is a little fan blade, little fan blade is installed in motor internal, and little fan blade spreads out the heat that the dc fan circuit control panel distributes uniformly, its structure more complicated.Also having a kind of is that radiator is made gilled radiator, radiator is installed on the dc fan circuit control panel, and the dc fan circuit control panel is installed on the spiral case side plate, the shortcoming of An Zhuaning is that the volume of radiator is big like this, the cost of production height, the volume conference influences the air intake of air inlet, and air quantity can lose.
Summary of the invention
The utility model is to overcome the deficiencies in the prior art and the centrifugal dc fan of forward direction that the low and good heat dissipation effect of a kind of simple in structure, cost of production is provided.
In order to achieve the above object, the utility model is achieved in that it is the centrifugal dc fan of a kind of forward direction, comprises volute casing, is fixed on forward-type centrifugal wind wheel, dc fan circuit control panel and radiator in the volute casing; It is characterized in that: described radiator is a planar heating panel, it is fixed on outside the side plate of volute casing, be provided with several radiation holes on side plate, the position of radiation hole is corresponding with Heat sink, and described dc fan circuit control panel is installed on the Heat sink.
Also comprise the outer cover that covers on the dc fan circuit control panel, outer cover is fixed on outside the side plate of volute casing.
The utility model advantage compared with prior art is the low good heat dissipation effect that reaches of simple in structure, cost of production.

Fig. 1 is the stereogram for the centrifugal dc fan of traditional forward direction;
Fig. 2 is a stereogram of the present utility model;
Fig. 3 is an exploded view of the present utility model;
Fig. 4 is the stereogram of the utility model another side.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description:
Shown in Fig. 2 to 4, it is the centrifugal dc fan of a kind of forward direction, comprises volute casing 2, is fixed on forward-type centrifugal wind wheel 3, dc fan circuit control panel 5 and radiator in the volute casing; The utility model characteristics are: radiator is a planar heating panel 6, Heat sink is fixed on outside the side plate of volute casing 2, be provided with several radiation holes 21 on side plate, the position of radiation hole is corresponding with Heat sink, and dc fan circuit control panel 5 is installed on the Heat sink; This Heat sink can be made of simple aluminium sheet, and mould also is simple punching mould, and its overall cost is low.
During 3 operations of forward-type centrifugal wind wheel, there is powerful air flows volute casing 2 inside, thereby the heat on the Heat sink 6 is passed by radiation hole 21, can effectively dispel the heat to dc fan circuit control panel 5.
In the present embodiment, also comprise the outer cover 4 that covers on the dc fan circuit control panel 5, outer cover is fixed on outside the side plate of volute casing 2, and this outer cover has played protective action to the dc fan circuit control panel.
Claims (2)
1. the centrifugal dc fan of forward direction comprises volute casing, is fixed on forward-type centrifugal wind wheel, dc fan circuit control panel and radiator in the volute casing; It is characterized in that: described radiator is a planar heating panel (6), it is fixed on outside the side plate of volute casing (2), on side plate, be provided with several radiation holes (21), the position of radiation hole is corresponding with Heat sink, and described dc fan circuit control panel (5) is installed on the Heat sink.
2. the centrifugal dc fan of forward direction according to claim 1 is characterized in that: also comprise the outer cover (4) that covers on the dc fan circuit control panel (5), outer cover is fixed on outside the side plate of volute casing (2).
