Abstract

The invention discloses a device for controlling heat dissipation of a switching power module. The device comprises a heat-dissipating fan, wherein the heat-dissipating fan comprises a fan frame, and a stator and a rotor which are accommodated inside the fan frame; the rotor can rotate relative to the stator; a wheel hub and a plurality of fan blades extending out from the wheel hub sleeve on the rotor; the wheel hub adopts a hollow structure; the wheel hub comprises a shell and a cavity; an annular airbag is arranged on the inner wall, near the rotor side, of the cavity; the annular airbag is filled with table vinegar; the table vinegar is boiled to produce gas to expand the annular airbag; one ends of the fan blades are fixedly connected with the annular airbag; through slots for the fan blades to run through are formed in the shell; the other ends of the fan blades run through the through slots and extend out; serrated grooves are formed in the edges of the fan blades; shrinking grooves are formed in the shell on the two sides of the through slots; conical baffle plates extending out towards the through slots and capable of being clamped into the serrated grooves to fix the fan blades are arranged inside the shrinking grooves; the conical baffle plates can be shrunk into the shrinking grooves. The device can solve the problem that the heat-dissipating device of the switching power module in the prior art cannot adjust the air volume according to the temperature rise change.

Description

technical field [0001] The invention relates to the field of switching power supplies, in particular to a device for controlling heat dissipation of 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 p...
