Description
Technical field
The utility model relates to a kind of high power switching power supply.
Background technology
The structure of the high power switching power supply used at present is: the box Switching Power Supply housing comprising aluminum, box Switching Power Supply housing is enclosed by top board, base plate and four side side plates and forms, and the base plate top in box Switching Power Supply housing is straggly is distributed with passive electronic devices and components and magnetic elements.In high power switching power supply, magnetic elements (as inductance and transformer etc.) is main heating element, and the heat that passive electronic devices and components (as resistance and electric capacity etc.) distribute is less, the shortcoming of this high power switching power supply is: radiating effect is poor, Switching Power Supply is very easily made to be in the too high state of temperature, and then cause magnetic elements and passive electronic devices and components to damage because of excessive temperature, greatly reduce the useful life of Switching Power Supply.
Utility model content
The purpose of this utility model is to provide a kind of high power switching power supply of a kind of good heat dissipation effect, long service life.
For achieving the above object, the utility model have employed following technical scheme: described a kind of high power switching power supply, comprise: box Switching Power Supply housing, box Switching Power Supply enclosure interior is become the first chamber and the second chamber by baffle for separating, passive electronic devices and components and magnetic elements are placed in the first chamber and the second chamber respectively, the two side, front and back of the second chamber offers air inlet and air outlet respectively, air inlet is provided with the first radiator fan, in the bottom of box Switching Power Supply housing, some radiating fins are installed, radiating fin is also provided with the second radiator fan.
Further, aforesaid a kind of high power switching power supply, wherein: between magnetic elements and the base plate of the second chamber, be also provided with heat radiation copper coin, is also provided with heat radiation copper coin between passive electronic devices and components and the base plate of the first chamber.
By the enforcement of technique scheme, the utility model has the advantage of good heat dissipation effect, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of high power switching power supply described in the utility model.
Fig. 2 is the structural representation of the left apparent direction of Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, described a kind of high power switching power supply, comprise: the box Switching Power Supply housing 1 of aluminum, box Switching Power Supply housing 1 inside is separated into the first chamber 3 and the second chamber 4 by dividing plate 2, passive electronic devices and components 5 are separately placed in the first chamber 3 and the second chamber 4 with magnetic elements 6, by the passive electronic devices and components 5 of a small amount of heat and the mutually isolated placement of magnetic elements 6 that can continue to give out amount of heat during work only will can be given out during work, thus the heat making magnetic elements 5 distribute can not have influence on passive electronic devices and components 3, and then decrease the probability that passive electronic devices and components 3 damage because temperature is too high, the front and rear sides wall of the second chamber 4 offers air inlet 7 and air outlet 8 respectively, being provided with the first radiator fan 9, first radiator fan 9 at air inlet 7 place can make the air outside the air in the second chamber 4 and box Switching Power Supply housing 1 carry out forced convertion heat radiation, in the bottom of box Switching Power Supply housing 1, some radiating fins 10 are installed, heat conduction on box Switching Power Supply housing 1 can be walked by radiating fin 10 quickly, radiating fin 10 is also provided with the second radiator fan 11, the heat conducting to radiating fin 10 can dissipate by the second radiator fan 11 quickly, further increases the radiating effect of Switching Power Supply, in the present embodiment, the copper coin 12 that dispels the heat also is provided with between magnetic elements 6 and the base plate of the second chamber 4, also the copper coin 12 that dispels the heat is provided with between passive electronic devices and components 5 and the base plate of the first chamber 3, because the heat-conducting effect of the copper coin 12 that dispels the heat is better than the box Switching Power Supply housing 1 of aluminum, the heat that magnetic elements 6 and passive electronic devices and components 5 distribute can conduct by the copper coin 12 that thus dispels the heat quickly, further increases the heat dispersion of Switching Power Supply,
Operation principle of the present utility model is as follows: during work, open the first radiator fan 9 and the second radiator fan 11 simultaneously, the heat that passive electronic devices and components 5 give out can conduct to the heat radiation copper coin 12 bottom it, then conducts to the box Switching Power Supply housing 1 of aluminum through heat radiation copper coin 12, a part of heat that magnetic elements 6 gives out can conduct the heat radiation copper coin 12 caused bottom it, cause the box Switching Power Supply housing 1 of aluminum again through the conduction of this heat radiation copper coin 12, another part heat that magnetic elements 6 gives out can be dissipated in the air outside box Switching Power Supply housing 1 by the first radiator fan 9 forced convertion, when the heat conduction of passive electronic devices and components 5 and magnetic elements 6 is to box Switching Power Supply housing 1, these heats also can conduct the radiating fin 10 be dissipated to bottom box Switching Power Supply housing 1, the heat conducting to radiating fin 10 can dissipate by the second radiator fan 11 quickly simultaneously, the heat that passive like this electronic devices and components 5 and magnetic elements 6 give out just can shed box Switching Power Supply housing 1 timely, make that box Switching Power Supply inside can not temperature be too high because passive electronic devices and components 5 and magnetic elements 6 dispel the heat not in time, and then guarantee that passive electronic devices and components 5 and magnetic elements 6 can not damage because of excessive temperature, further increase the useful life of Switching Power Supply.The utility model has good heat dissipation effect, the advantage of long service life.
