Description

Technical Field

[0001] The utility model relates to the technical field of power supply, in particular to a heat exchange type voltage-stabilized power supply. Background Art

[0002] A voltage-stabilized power supply is a power supply device that can provide a stable output voltage. In the power system, the voltage of the input power supply may fluctuate due to various reasons. The function of the voltage-stabilized power supply is to convert these unstable voltages into stable and reliable output voltages to meet the voltage stability requirements of electronic equipment.

[0003] A voltage-stabilized power supply with reference announcement number CN218649155U has a side wall of a power supply body movably mounted with a heat dissipation component and a filter for heat dissipation and ventilation of the power supply body. The heat dissipation component is detachably connected to the power supply body through a plug-in portion, and the filter is placed at the ventilation hole of the power supply body, and the heat dissipation component is pushed downward, and the locking portion is driven downward by the heat dissipation component. The wall surface of the push rod of the locking portion pushes the thrust portion close to the ear plate, and when the key slot moves to face the rib, the rib enters the key slot, and the rib enters the position of the limit locking portion in the key slot to fix the heat dissipation component. At the same time, the thrust portion is locked through the elastic connection between the thrust portion and the ear plate. The locking part applies a force perpendicular to the side wall of the power supply body, and the filter is pressed against the wall of the power supply body by the locking part. The pressure applied by the heat dissipation component to the filter is more uniform, and the filter frame fits more closely to the power supply body, which can reduce the gap between the filter and the power supply body. According to the above, although the voltage-stabilized power supply can be well applied, the fan heat dissipation method is usually used to cool the inner parts of the power supply box body. Although it is equipped with related parts such as filters, some dust will still flow into the power supply box body and erode its inner parts, and external water sources will also erode the inner parts of the power supply box body, which needs to be improved.
