Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing power demand in cloud computing and AI systems, combined with limited space for power supplies, particularly in width, poses challenges for thermal cooling and airflow, while standard power supply sizes restrict the installation of additional devices like LEDs due to space constraints.
Innovation Solution
A fan design with a fan frame and reserved spaces at the corners of the outer casing, allowing for positioning holes for assembly and accommodating wires or LEDs, maintains airflow and heat dissipation performance while optimizing space usage in compact power supplies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fan with smaller width than the width of the power supply is selected to leave a path for the wires inside the power supply, then the wire path is provided, but the airflow capability is reduced and thermal cooling performance deteriorates
Solution Approach 1:
The patent utilizes the corner spaces of the power supply housing, which are previously unused areas. By positioning the fan such that its outer surface creates reserved spaces with the corner surfaces of the housing, the design effectively uses the vertical and depth dimensions of the corner regions to accommodate wires, rather than reducing the fan width in the horizontal plane. This maintains the fan's full width for airflow while providing wire pathways in the corner reserved spaces.
2Productivity
If the power supply width is reduced to increase power density, then power density improves, but thermal cooling becomes more challenging due to increased airflow resistance
Solution Approach 1:
The patent segments the power supply interior into functional zones by utilizing the corner spaces. The corner reserved spaces created by the fan's outer surface and housing corners serve as dedicated wire pathways, separating wire routing from the main airflow channel. This segmentation allows the fan to maintain its full width for optimal airflow while providing dedicated spaces for wire management, thus reducing airflow resistance despite the compact power supply dimensions.
3Power
If a socket with higher-level power is used to meet current carrying capacity requirements, then current capacity is sufficient, but the socket size increases and no space remains to install other devices like LED on the front panel
Solution Approach 1:
The patent merges the fan structure with additional functional elements by integrating the LED light source and control circuitry into the fan assembly. The reserved spaces created by the fan's outer surface and housing corners are utilized to accommodate the LED and its wiring. This integration allows the power supply to have both the required high-power socket and LED indicators within the same front panel area, eliminating the space conflict between socket size and LED installation.

AI summary
A power supply device includes an outer casing, a fan and a wire. Wherein the outer casing has four sides, wherein two adjacent ones of the four sides intersect, thus forming four corners. A central axis of which being parallel to an extending direction of the outer casing, and the fan being placed in the outer casing to divide the power supply device into a first part and a second part. The fan includes a fan frame having three positioning holes adjacent to any three of the four corners of the outer casing, wherein the fan frame has no positioning hole adjacent to the remaining corner of the four corners of the outer casing which forms a reserved space. The wire is connected to the second part from the first part of the power supply device through the reserved space.
