Abstract

The utility model provides a double-blower fan switching power supply for computers, which comprises a housing, a circuit board, a heat radiating sheet, and blower fans. The utility model is characterized in that a blower fan is also arranged on the other side, opposite to the blower fan, of the housing. The utility model can effectively increase the flow speed of air in the switching power supply to ensure that heat generated in a computer during the running of the computer can be rapidly radiated to the outside of the computer, so that the working stability of the switching power supply is guaranteed, and the service life is extended. The utility model is suitable for switching power supplies of computers.

Description

Two blower fan computer switching power supplies

The utility model relates to power supply, particularly a kind of pair of blower fan computer switching power supply.

The action need of computing machine has a stable working power, and the temperature of the job stability of power supply and its internal heating element just has much relations.Along with the increasing of power, the thermal value of its rectifier cell just increases.Though strengthen the size of heat radiator the power supply internal temperature is slightly descended, the increasing of heat radiator must make the area of printed board strengthen, and has consequently increased the weight of the weight of whole power supply, has hindered computer switching power supply to develop to miniaturization and lightness direction.

The purpose of this utility model is to provide a kind of two blower fan computer switching power supplies that can reduce power supply internal work temperature under the situation of the size that does not increase heat radiator.

Task of the present utility model realizes by this way: this Switching Power Supply includes shell, wiring board, and heat radiator and blower fan is characterized in that the typhoon machine that also is provided with on the another side shell relative with blower fan.

But from above-mentioned improvement wind, because the utility model is provided with a typhoon machine at original air outlet place, make to form a complete air channel in the shell between two blower fans, obviously add the convection current of whole air, make the heat that heat radiator produced that is in this air channel be dispersed into the outside quickly.Show that after tested when the blower fan that adopts one 8 * 8 centimetres, the temperature in the Switching Power Supply is about 80 ℃, and after adopting two 8 * 8 centimetres blower fan, this temperature is just reduced to 55~61 ℃, its radiating effect is fairly obvious.Therefore, compared with the prior art the utility model has the size that need not increase heat radiator and can effectively reduce Switching Power Supply internal work temperature, obtains better heat radiating effect, improves the advantage of Switching Power Supply job stability.

Below in conjunction with accompanying drawing structure of the present utility model is further described.

Fig. 1 is the vertical view cut-open view of a kind of concrete structure of the utility model.

As shown in Figure 1, shell 1 of the present utility model, wiring board 2, heat radiator 3 and blower fan 4 and existing Switching Power Supply basically identical, institute's improvements are also to be provided with a blower fan 5 on the relative another side shell 1 of blower fan 4.The model specification of blower fan 5 is identical with blower fan 4, adopts 8 * 8 centimetres mini fan, and its effect is comparatively desirable.

The utility model is fit to computer switching power supply to be adopted.

Claims (2)
