Power Converter Mounting Flange for Sealed Enclosure Servicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power converter mounting solutions, such as those with integral or add-on flanges, complicate servicing and increase costs due to complex integration and potential sealing issues, while failing to provide versatile sealing solutions for various enclosure specifications like NEMA Type 4/4X, NEMA Type 12, UL Type 12, IP5X, and IP6X applications.
Innovation Solution
A power converter mounting system featuring a flange with a through hole and fasteners that allow the converter to extend through an enclosure, with a sealing member between the flange and the converter's lip, enabling easy installation and servicing from the same side, and a cover with additional sealing members to maintain protection levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an add-on flange is provided to seal the converter to the enclosure, then sealing capability is improved, but device complexity and cost increase
Solution Approach 1:
The mounting assembly is divided into separate components: a flange that seals to the enclosure and a converter that mounts to the flange. This segmentation allows the flange to provide sealing independently while the converter can be serviced separately, reducing overall system complexity.
Solution Approach 2:
The sealing function is extracted into a dedicated flange component that can be independently installed and sealed to the enclosure. This separates the sealing requirement from the converter housing, allowing the converter to be serviced without compromising the seal.
2Reliability
If the converter is sealed to the enclosure with a flange, then protection level is maintained, but ease of servicing deteriorates
Solution Approach 1:
The system is segmented into a permanently sealed flange-enclosure assembly and a removable converter. The flange maintains the protection level when sealed to the enclosure, while the converter can be independently removed and serviced without disturbing the seal.
Solution Approach 2:
The converter is extracted as a separate serviceable component that mounts to the flange rather than being permanently integrated. This allows the converter to be removed for servicing while the flange-enclosure seal remains intact.
3Adaptability or versatility
If different housings are manufactured for each converter according to installation environment, then adaptability to different enclosures is improved, but manufacturing cost increases
Solution Approach 1:
The flange is designed as a universal component that can seal to various enclosure types (NEMA 12, 4, 4X, UL 12, IP5X, IP6X) through standardized sealing mechanisms. This allows a single converter model to be adapted to different enclosure environments by simply mounting to the appropriate flange rather than manufacturing different housings.

AI summary
The present invention provides a power converter mounting system including a flange that cooperates with a power converter and an enclosure. The flange includes a through hole that cooperates with an opening in the enclosure to permit the power converter to extend therethrough. A number of fasteners connect to the flange and overhang a portion of the power converter. The fasteners are configured to be manipulated from a front side of the power converter. An outer perimeter of the flange extends beyond the opening in the enclosure. The flange is secured to the enclosure with a number of fasteners that are also operable from the front side of the power converter. The power converter mounting assembly is configured to secure a power converter to an enclosure so as to satisfy a variety of sealing requirements as well as allowing convenient servicing of the power converter system.
