IP44 protection heat dissipation structure based on 2U-height power electronic equipment

Abstract

The invention relates to an IP44 protection heat dissipation structure based on 2U-height power electronic equipment. A metal mesh is welded to an inner side of the bottom of an air guiding structure,and is fixedly connected with an installation base through a fastening device. The joint of the installation base and the 2U-height power electronic equipment is provided with a waterproof pad shapedlike a rectangular ambulatory, and the waterproof pad shaped like the rectangular ambulatory is pressed by the fastening device, thereby achieving the waterproof effect between the protection heat dissipation structure and an equipment connection part, and forming the complete IP44 protection heat dissipation structure of the 2U-height power electronic equipment, and achieving the protection andheat dissipation effect of the IP44 housing. The structure provided by the invention is applicable to all 2U standard height power electronic equipment, and the lateral width and the ventilation areacan be adjusted according to actual needs. The structure is good in applicability and is small in limitation. The structure cancels a middle waterproof and dustproof cotton, reduces the barrier effectof waterproof and dustproof cotton on exhaust air, and improves the IP44 protection and heat dissipation capability of 2U-height power electronic equipment.

Description

technical field [0001] The invention relates to an IP44 protection and heat dissipation structure of electronic equipment, in particular to an IP44 protection and heat dissipation structure suitable for 2U high power electronic equipment with shell protection, ventilation and heat dissipation requirements. Background technique [0002] 1. IP44 shell protection requirements: [0003] According to the provisions of "GB / T 4208-2008 Enclosure Protection Level (IP Code)", the IP44 enclosure protection level requirements of existing electrical equipment should meet the following requirements: [0004] a) Prevent the human body from approaching the dangerous parts in the shell; [0005] b) prevent solid foreign matter from entering the equipment in the enclosure; [0006] c) Prevent the impact on the equipment caused by water entering the shell. [0007] 2. The composition and principle of the existing IP44 shell protection and heat dissipation structure: [0008] The existing ...

AI Technical Summary

Problems solved by technology

[0013] The present invention is to provide an IP44 protective heat dissipation structure based on 2U height power electronic equipment. In order to solve the problem that the existing IP44 protection heat dissipation structure is limited in size, it is not suitable for the current mainstream 2U height power electronic equipment, and the ventilation area is small. The heat dissipation is small and the heat dissipation ability is poor, which cannot effectively prevent the 360° splash water from entering the casing, and improve the casing protection and heat dissipation ability of 2U high power electronic equipment
