Adjustable Blanking Panel for Rack Air Recirculation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixed-height blanking panels in cabinets and enclosures fail to effectively prevent the reentry of heated exhaust air into the air intake of electrical and computer equipment, leading to overheating and equipment failures, especially as equipment configurations change, requiring frequent replacement and increased labor and costs.
Innovation Solution
A height-adjustable blanking panel system that includes a base member and a sliding member with mounting holes, allowing the panel to be removably coupled to mounting rails and slid relative to the base member to adjust its height, preventing the reentry of heated air and accommodating varying equipment configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed-height blanking panels are used to block vacant sections in racks, then the panels can prevent air recirculation, but the panels cannot be adjusted when equipment configuration changes, requiring removal and replacement
Solution Approach 1:
The blanking panel incorporates a sliding member that can move vertically within channels formed by retaining members, transforming a static fixed-height panel into a dynamic adjustable structure. This allows the panel height to be changed by sliding the sliding member to different positions and securing it with fasteners, enabling adaptation to various rack configurations without requiring multiple different panel sizes.
2Adaptability or versatility
If multiple fixed-size blanking panels are kept on hand for different configurations, then the correct panel size is available, but the cost and storage space increase
Solution Approach 1:
The adjustable blanking panel is designed as a universal solution that can serve multiple rack configuration needs. By incorporating the sliding member mechanism, a single panel design can be adjusted to fill various heights of vacant sections, replacing the need to maintain inventory of multiple fixed-size panels in different quantities.
3Productivity
If fixed-height blanking panels are installed in densely packed cabinets, then air flow can be blocked, but the panels cannot be repositioned when equipment is reconfigured, leading to labor hours being expended
Solution Approach 1:
The sliding member mechanism allows the blanking panel to be dynamically repositioned along the mounting rail. When equipment reconfiguration is needed, the fasteners can be removed and the sliding member slid to a new position, enabling quick adaptation without complete panel replacement and reducing labor hours for reconfiguration tasks.

AI summary
Adjustable blanking panels for use with equipment racks and enclosures to cover or fill in vacant sections of the rack or enclosure, to prevent the circular flow and reentry of high temperature air into the intake of electrical and computer equipment. The adjustable blanking panels include a generally rectangular base frame that defines opposing left and right side channels, and a generally rectangular shield that is adapted to be inserted into the side channels and slide relative to the base frame, to adjust the height of the panel to the size of the vacant section. The adjustable blanking panel may further include a lip that may be used to raise or lower the shield.
