Accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, novel switched power supply of the present utility model, comprise housing 1 and be arranged on the electronic component 2 in housing, housing comprises cover plate 11, side plate 12 and base plate 13, on cover plate 11, be provided with fan through hole and be fixed with fan 3 in the outer end of fan through hole, the bottom of fan 3 is provided with a plurality of tops briquetting 4; The bottom of base plate 13 is provided with the bolt mounting groove 14 of depression to the inside, in bolt mounting groove 14, is provided with installing hole, is provided with adjusting bolt 15 in installing hole, and the top of adjusting bolt 15 is provided with top board, on top board, by spring 16, is connected with lower fin 5; The lower surface of the end face of lower fin 5 and electronic component 2 attaches mutually, is provided with and the mutually attached upper fin 6 of electronic component 2 upper surface between electronic component 2 and top briquetting 4; In housing 1, be also provided with a plurality of radiating tubes 7, the bottom of radiating tube 7 communicates with the bottom of side plate 12, and the top of radiating tube 7 communicates with the bottom of fan 3, and the inside top of radiating tube 7 attaches mutually with the side of upper fin 6 and lower fin 5 respectively; The top of radiating tube 7 and bottom are respectively arranged with the first thermoreceptor 8 and the second thermoreceptor 9, in housing 1, are provided with temperature detect switch (TDS), and the first thermoreceptor 8 is connected with fan 3 by temperature detect switch (TDS) with the second thermoreceptor 9.
During use, Switching Power Supply of the present utility model, its heat sinking function mainly comprises two kinds of modes, natural heat dissipation and active heat removal, these two kinds of modes have some common ground: the heat that electronic component produces directly dispels the heat by upper fin, also heat is passed to radiating tube simultaneously, lower fin is passed to radiating tube by heat, because upper fin has more the heat-dissipating space on top, thereby in radiating tube, the hottest air is positioned at the position that lower fin and radiating tube attach mutually, like this, the upper fin of this part air driven top and the air of radiating tube phase sticking position, rise upward, then in radiating tube, form air-flow from bottom to top, Here it is natural heat dissipation, when the radiating tube top of the first thermoreceptor and the second thermoreceptor monitoring and the temperature of bottom higher, or temperature difference is when little, temperature detect switch (TDS) starts fan, forms initiative radiating airflow in radiating tube.The effect that it should be noted that top briquetting is to make to form heat radiation cavity between fan and upper fin, and lower fin relatively radiating tube slides, and so just can control by set screw the attaching situation of fin and lower fin and electronic component.
In order to prevent the savings heat of other positions in housing, novel switched power supply of the present utility model, is also provided with a plurality of radiator windows on base plate 13 and side plate 12, is provided with a plurality of weather strips side by side on radiator window.
Slip for convenient lower fin, anti-skidding is inhomogeneous causes the problem that do not attach completely, novel switched power supply of the present utility model, and the inner side of radiating tube 7 is provided with chute, the edge of lower fin is provided with slide block, and slide block is relative sliding in chute.
