Embodiment Construction

[0023] The present invention will be described in further detail below by means of specific embodiments:

[0024] The reference numerals in the accompanying drawings include: fan frame 1, stator 2, rotor 3, hub 4, housing 41, through groove 411, contraction groove 412, wedge-shaped baffle 413, cavity 42, fan blade 5, annular airbag 6. Feeding port 61.

[0025] The embodiment is basically as figure 1 , figure 2 Shown: the cooling method of the switching power supply module in the present embodiment, comprises the following contents:

[0026] 1) When the switching power supply works, 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. When the temperature of the heating element of the switching power supply exceeds 40°C, the vinegar in the annular airbag 6 boils and generates gas The annular airbag 6 is inflated, and the fan blade 5 connected to the ann...

Abstract

The present invention discloses a heat dissipation method of a switch power supply module. The method comprises the following content: 1) a switch power supply runs, a heat dissipation fan starts to rotate, temperature of heating devices in the switch power supply rises with the increasing of the working time of the switch power supply, when the temperature of the heating devices in the switch power supply exceeds 40 DEG C, vinegar in an annular air bag boils to generate gas to allow the annular air bag to be expanded, a radial pushing force is applied to fan blades connected on the annular air bag to allow the fan blade portions located in a cavity to pass through a through groove to extend to the external portion of the housing, the fan blades exposed out of the housing become longer, and the air volume generated by the heat dissipation fan is increased; 2) the temperature of heating devices is reduced, the annular air bag starts contraction, the fan blades exposed out of the housing become shorter, and the air volume generated by the heat dissipation fan is decreased; 3) the switch power supply stops running, the heat dissipation fan stops rotation, the air in the annular air bag is cooled to form liquid, the annular air bag is contracted, and the fan blades are reset. The heat dissipation method of the switch power supply module realizes regulation of air volume in the heat dissipation process through the physical effect so as to reduce the measurement errors.

Description

technical field [0001] The invention relates to the field of switching power supplies, in particular to a heat dissipation method for a switching power supply module. 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 bec...
