Embodiment Construction

[0026] The present invention will be described in further detail below by means of specific embodiments:

[0027] The reference numerals in the accompanying drawings include: fan frame 1 , stator 2 , rotor 3 , hub 4 , blade set 5 , upper blade 6 , lower blade 7 , chute 8 , airbag 9 , and slider 10 .

[0028] The embodiment is basically as figure 1 , figure 2 , image 3 , Figure 4 Shown:

[0029] Heat dissipation methods for switching power supplies, including the following:

[0030] 1) When the switching power supply is working, the cooling fan starts to rotate. As the working time of the switching power supply becomes longer, the temperature of the heating element in the switching power supply rises. The gas generated by the boiling of vinegar makes the airbag expand, and the inflated airbag pushes the slider on the lower fan blade to slide on the chute, so that the upper fan blade and the lower fan blade of the fan blade group are staggered, and the air volume generat...

Abstract

The invention discloses a heat dissipation method for a switching mode power supply, and the method comprises following contents: 1) the switching mode power supply works, a cooling fan starts to rotate, the temperature of a heating device in the switching mode power supply rises with the the work time of the switching mode power supply, when the temperature of the heating device in the switching mode power supply is over 40 DEG C, vinegar in an air bag in a sliding groove boils to generate gas so as to enable the air bag to inflate, the inflated air bag pushes a sliding block on a lower fan blade to slide on the sliding groove, an upper fan blade and the lower fan blade are staggered, and the quantity of wind is increased; 2) the temperature of the heating device is reduced, the gas generated by the vinegar in the air bag starts to reduce, the air bag starts to contract, the upper fan blade and the lower fan blade gradually overlap, and the quantity of the wind is reduced; 3) the switching mode power supply stops working, the cooling fan stops rotating, the gas in the air bag cools to form liquid, the air bag contracts, the sliding block resets, and the upper fan blade and the lower fan blade completely overlap. According to the invention, the scheme can solves a problem that a switching mode power supply module heat dissipation device can not regulate wind quantity according to the temperature rising variation.

Description

technical field [0001] The invention relates to the field of switching power supplies, in particular to a heat dissipation method for switching power supplies. Background technique [0002] With the rapid development of power electronics technology, the relationship between power electronic equipment and people's work and life is becoming increasingly close, and electronic equipment is inseparable from a reliable power supply. In the 1980s, the computer power supply fully realized the switching power supply, and took the lead in completing the computer. In the 1990s, switching power supplies entered various electronic and electrical equipment fields one after another. Program-controlled switches, communications, electronic testing equipment power supplies, control equipment power supplies, etc. have widely used switching power supplies, which has promoted the rapid development of switching power supply technology. . [0003] As the size of the signal power module becomes sm...
