Large-power island special power supply module cooling device and temperature control method thereof

Abstract

The invention discloses a large-power island special power supply module cooling device and a temperature control method thereof. A specific position obtained by a temperature monitoring module is subjected to temperature analysis, a thermal model of a sealed cavity is established, particle swarm optimization is used for correcting the established model, the model can more accurately describe a machine box temperature change process, adaptivity and prediction control reliability are improved, and a master control module realizes the wind regulation of fans in different air flues and cavities on the basis of model prediction control and particle swarm optimization. The cooling structure is combined with a control strategy, the cooling structure accelerates heat to be evenly distributed andquickly scattered, cooling efficiency is obviously improved through the independent control and the mutual cooperation of each wind enhancement component, and the effective cooling of the large-powerisland special power supply under a high-temperature environment is realized.

Description

technical field [0001] The invention relates to a cooling device for a high-power sea-island special power supply module and a temperature control method thereof, which are suitable for heat dissipation treatment of the sea-island special power supply. Background technique [0002] In the field of power electronics technology, power devices and inductors and capacitors will generate heat due to their own losses. The heat will cause the temperature of the device to rise, the light one will not work normally and affect the service life, and the severe one will be damaged immediately. Therefore, corresponding heat dissipation measures will be taken for each device. Currently known heat dissipation technologies include natural convection cooling using heat sinks; forced convection cooling using heat sinks plus fan external force; flow dynamic cooling with heat pipes; liquid cooling using micro-tube cooling plates. The first two heat dissipation methods are mostly suitable for l...

Problems solved by technology

[0003] The environment of the island is harsh, the annual average humidity is as high as 85%, the surface temperature in summer is as high as 60°C, and the temperature difference between day and night is large. High salt spray, high humidity, and high temperature difference bring great challenges to the long-term reliable operation of power supply equipment: Short-circuit fryer, high salt spray leads to corrosion of circuit boards and damage to the fryer, overheating causes rapid aging of equipment and frequent failures
