Abstract

The invention relates to the field of a switch power supply, is to solve the problem that energy consumption of the switch power supply can be increased when the switch power supply is cooled through a heat radiation fan, and provides a heat dissipation device for a switch power supply. The heat dissipation device comprises a housing. The housing is equipped with an electronic component of the switch power supply. A cover plate is arranged above the housing. The cover plate comprises a fixation portion and an extensible movable portion. The fixation portion of the cover plate is uniformly provided with connection holes; and the connection holes are used for connecting the movable portion. A retractable heat dissipation member is arranged between the cover plate and the housing. The heat dissipation member is arranged on the upper end surface of the housing and is internally provided with a cavity filled with water. The heat dissipation member can extends along the side surface of the housing under the function of the movable portion.

Description

technical field [0001] The invention relates to the field of switching power supplies, in particular to a cooling device for switching power supplies. Background technique [0002] The use of electrical appliances has been fully popularized, and an indispensable part of various electrical appliances is switching power supply. Switching power supply is a kind of power supply that uses modern power electronic technology to control the time ratio of switching on and off to maintain a stable output voltage. Switching power supplies are generally composed of pulse width modulation (PWM) control ICs and MOSFETs. With the development and innovation of power electronics technology, switching power supply technology is constantly innovating, which provides a broad development space for switching power supply. However, during the use of electrical appliances, it is inevitable that they will generate heat. The reason is that when the electrical appliances are working, the circuit wil...
