Solution Overview
Problem
Conventional heat exchanger designs are inadequate for effectively dissipating heat from high-power electronic components due to limitations in their ability to facilitate multi-directional fluid flow, which is essential for efficient heat transfer.
Innovation Solution
A fenestrated housing assembly that includes a plenum with a primary aperture for housing a fluid mover and a housing body with fenestrations, allowing for multi-directional fluid flow to enhance heat dissipation by directing fluid flow with respect to a secondary medium, either as an ingress or egress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional plate fin heat exchangers are used, then manufacturing cost and simplicity are reduced, but heat dissipation capability for high-power components is insufficient
Solution Approach 1:
The housing is divided into multiple segments with fenestrations (openings) distributed across different surfaces. This segmentation allows fluid to enter and exit through multiple discrete locations, creating complex multi-directional flow patterns that enhance heat dissipation while maintaining a relatively simple manufacturing process for each individual housing segment.
Solution Approach 2:
The invention transitions from conventional single-direction or two-directional flow to multi-directional flow by positioning fenestrations on multiple surfaces of the housing. This dimensional expansion of fluid flow paths allows cooling fluid to approach the heat exchanger from multiple angles, significantly improving heat dissipation effectiveness for high-power components.
2Device complexity
If traditional heat exchanger designs are used, then device complexity is reduced, but multi-directional fluid flow capability is insufficient
Solution Approach 1:
The housing structure serves multiple functions simultaneously: it provides structural support, directs fluid flow through strategically positioned fenestrations, and enables multi-directional cooling. The fenestrations act as both structural features and fluid flow control elements, allowing a single component to achieve both structural simplicity and flow versatility.
Solution Approach 2:
The fluid flow pattern is made dynamic and adaptable by positioning fenestrations to receive fluid from multiple directions. The housing structure accommodates varying flow conditions by allowing fluid to enter through different fenestration configurations depending on the operational requirements, providing adaptability without increasing structural complexity.

AI summary
Embodiments relate to a system and method for dissipating heat from a heat generating component. The system and method an assembly of a fenestrated housing and a plenum and positioning of the assembly relate to the heat generating component. The plenum accommodates a fluid mover relative to the fenestrated housing. The fenestrations function to support multi-directional fluid flow created by the fluid mover and accommodated by the fenestrations, which function as ports to direct fluid with respect to the heat generating component.
