Power supply module with quick-release filter screen

Abstract

The invention relates to a power supply module with a quick-release filter screen. The power supply module comprises a shell, a fan, a filter screen frame and a filter screen, the shell is provided with a panel, and a ventilation opening is formed in the panel. The fan is arranged in the shell and corresponds to the ventilation opening; the filter screen frame is detachably arranged on the panel and corresponds to the ventilation opening; the filter screen is detachably arranged on the filter screen frame and covers the ventilation opening. Therefore, when the filter screen needs to be replaced, the filter screen can be replaced only by directly detaching the filter screen frame from the outer part of the enclosure without detaching the enclosure, so that the power supply module does not need to be moved out of the system through power failure, and the effect of quickly detaching and replacing the filter screen can be achieved.

Description

technical field [0001] The invention relates to a power supply module, in particular to a power supply module which can quickly replace the filter screen without power interruption. Background technique [0002] With the gradual development of industry and technology, the content of fine suspended particles and dust in the air is gradually increasing. In order to reduce the damage of the electronic parts in the power supply module from the influence of suspended particles or dust in the air, a filter screen is generally added at the air inlet of the power supply module to isolate the suspended particles or dust and prevent them from being damaged. damage caused. [0003] In the prior art, the power supply module includes a casing, a fan and a filter. Air vents are formed on the outer panel of the casing. The fan is arranged in the casing and faces the air vent. The filter screen is arranged in the casing, and is located between the fan and the air vent. In this way, the...

AI Technical Summary

Problems solved by technology

The above-mentioned replacement process is not only cumbersome and time-consuming, but also prone to man-made damage during the disassembly process, and also requires a power outage to suspend the operation of the entire system, which will lead to an increase in the overall cost

[0005] Moreover, the expected service life of a general power supply module is 10 years. If the power supply module is used in an environment with harsher air quality, the filter needs to be replaced more frequently; The number of times will be very considerable, so the adverse effects of the aforementioned shortcomings will be further exacerbated

Therefore, the power supply module of the prior art really needs to be improved
