Solution Overview
Problem
Existing server radiators struggle to efficiently dissipate the high heat generated by high-performance computer chips, which can reach power rates of 300˜500 W, leading to inadequate heat management.
Innovation Solution
A detection device comprising a base with an internal space and a light channel, a light emitting element, a light receiving element, a conical reflector as the first optical element, and another conical reflector as the second optical element, which together enable the emission, reflection, and reception of light beams for detecting environmental objects without the need for complex rotating structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a conventional radiator structure is used, then the structure is simple and easy to manufacture, but the heat dissipation capability is insufficient for high-power chips (300-500 W)
Solution Approach 1:
The radiator is divided into multiple independent heat dissipation units, each equipped with its own heat dissipation fin array. This segmentation allows each unit to independently manage heat from specific chip regions, thereby increasing overall heat dissipation capability while maintaining modular simplicity in structure and manufacturing.
2Adaptability or versatility
If the light beam is emitted in a single direction, then the optical path is simple, but the detection range is limited
Solution Approach 1:
The patent transforms the light beam from a single-direction linear path into a two-dimensional circumferential distribution by introducing a conical reflector. This dimensional change enables the detection device to cover a wide circumferential range without requiring mechanical rotation or multiple optical channels, thus expanding detection range while keeping the optical structure relatively simple.
3Adaptability or versatility
If a rotating structure is used to achieve circumferential detection, then the detection range is comprehensive, but the structure becomes complex and costly
Solution Approach 1:
The patent replaces the mechanical rotating system with a stationary conical reflector that optically redirects the light beam in a circumferential direction. This substitution eliminates moving parts, reducing structural complexity, manufacturing costs, and maintenance requirements while achieving comprehensive circumferential detection coverage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The detection device effectively achieves circumferential range detection without rotation, simplifying the structure and reducing costs, while also allowing for adjustable detection ranges by controlling the light beam distribution and reflection areas.

AI summary
A detection device comprises a light emitting element, a first optical element and a light receiving element. The light emitting element is configured for emitting a first light beam. The first optical element is arranged on an optical path of the first light beam, and capable of reflecting the first light beam to form a second light beam transmitting in different directions circumferentially at the same time. The second light beam can be reflected by objects on an optical path of the second light beam to form a third light beam. The light receiving element is configured for receiving the third light beam.
