Abstract
The utility model relates to a converter heat-dissipation air channel device consisting of a shell, a printed circuit board and a fan, a transformer and a radiator arranged on the printed circuit board. An upper shell clings to the upper axis end of the fan; the fan is provided with only half a frame; the transformer and the radiator are arranged on the air-out side of the fan. Because the fan axis is perpendicular to the printed circuit board, height of the converter is efficiently reduced and air absorbed by the fan blows the transformer and the radiator and efficiently takes away heat to realize the purpose of cooling.
Description
Technical field
The utility model relates to a kind of heat abstractor of transducer, refers to a kind of air-duct apparatus by the blower fan heat radiation especially.
Background technology
Transducer on the market generally is used for changing low-voltage DC into civil power at present, such as change the 12V/24V direct current into the 220V alternating current from the 12V/24V storage battery; In most cases be automobile-used, be from cigar lighter low-voltage DC is converted to civil power to supply the use of electrical equipment.Traditional transducer is generally used shell in heat radiation, if aluminium extruded type, radiating effect generally can meet the demands, yet aluminium extruded is capable often attractive in appearance inadequately; If plastic casing also will add radiator in addition, blower fan is set dispels the heat, therefore must do the space of transducer bigger, thereby cause the transducer volume bigger, carry also very inconvenient.If by optimizing the inner member setting, improve radiating efficiency and realize that the miniaturization of transducer is when the use that can make things convenient for the consumer greatly.
The utility model content
Technical problem to be solved in the utility model is to improve the efficient of transducer heat radiation, dwindles the volume of transducer and realizes high-power compactization.
The utility model is achieved through the following technical solutions: a kind of transducer heat dissipation wind channel device, and it comprises: housing, printed circuit board (PCB), and be arranged at blower fan, transformer and radiator on the printed circuit board (PCB); It is characterized in that: upper shell is close to axle head on the blower fan, and described blower fan only possesses a rim half.
As further improvement of the utility model, printed circuit board (PCB) is in blower fan placement hollow out, and described blower fan is axially perpendicular to the hollow out place that printed circuit board (PCB) is embedded at printed circuit board (PCB); Transformer and radiator are arranged a side of the no frame that is arranged at blower fan, and radiator is arranged at the transformer rear; And the height of radiator and transformer is lower than the height of blower fan.
As further optimization of the present utility model, transformer can be 2, and 2 transformers are oppositely arranged, between constitute an air duct; Radiator extends in the air duct.
As the improvement to blower fan of the present utility model, the side that described blower fan is removed frame is provided with a rib, and base is left in the bottom, and the height of described base is 1/4 of a blower fan height.
By above-mentioned setting, blower fan axially vertically is embedded at can save the height that the space reduces transducer on the printed circuit board (PCB), blower fan has only a rim half, last axle head and housing are close to, thereby realize that blower fan is from axial air draught, transformer is directly brushed in the side direction air-out and radiator is effectively taken away heat, realizes high-power, miniaturization.
Description of drawings
Fig. 1 is the utility model sectional arrangement drawing;
Fig. 2 is provided with stereogram for each element on the utility model printed circuit board (PCB);
Fig. 3 is provided with vertical view for each element on the utility model printed circuit board (PCB);
Fig. 4 is the utility model blower fan stereogram.
Embodiment
Lift a most preferred embodiment below and in conjunction with the accompanying drawings the utility model be elaborated as follows:
As shown in Figure 1: blower fan 2 is axially perpendicular to and is arranged on the printed circuit board (PCB) 6, and printed circuit board (PCB) 6 is in the placement of blower fan 2 hollow out, and blower fan 2 is embedded at wherein; Axle head is close to housing 1 on the blower fan 2, and lower shaft end is close to air inlet 12.
As Fig. 1,2., shown in 3: transformer 31,32 is symmetricly set in the right side of blower fan 2, forms an air duct between two transformers 31,32; One radiator 4 is arranged at the right side of transformer 31,32, and an end of radiator 4 gos deep among the air duct, and is close to blower fan 2.
As shown in Figure 4: 2 of blower fans have half of frame 22, be to guarantee the intensity of blower fan 2, and a side of removing frame is provided with a rib 23, and leave highly and to be blower fan 2 1/4 base 24 highly.
During transducer work, main heat comes from field effect transistor and the transformer 31 under the radiator 4,32, blower fan 2 sucks air from air inlet 12, because axle head 21 and housing 1 are close on the blower fan 2, wind just blows side to transformer 31 from blower fan 2 no frames one, 32 and radiator 4, because the height of blower fan 2 is higher than radiator 4 and transformer 31,32, and transformer 31,32 pin is welded on and makes transformer 31 on the printed circuit board (PCB) 6,32 and printed circuit board (PCB) 6 between leave the gap, the wind that blower fan 2 side direction blow out not only can flow to air outlet 11 along the space in the radiator 4, also can be from transformer 31,32 and the space up and down of radiator 4 in flow to air outlet 11, can be effectively with transformer 31,32 and radiator 4 on heat, make the heater element efficiently radiates heat.
