1Temperature

If conventional heat dissipation designs are used, then device complexity is low, but heat dissipation efficiency is poor leading to heat accumulation

Engineering Contradiction:

Solution Approach 1:

The heat dissipation device is divided into multiple independent fin assemblies (first, second, and third fin assemblies) arranged in different spatial directions. Each fin assembly acts as an independent heat dissipation unit, allowing optimized heat transfer pathways and improving overall heat dissipation efficiency without excessive complexity increase.

Inventive Principle:

Solution Approach 2:

The patent introduces a third fin assembly extending in a direction different from the first and second fin assemblies, transforming a planar two-dimensional heat dissipation structure into a three-dimensional multi-directional structure. This spatial expansion increases heat dissipation surface area and improves thermal management efficiency.

Solution Approach 1:

Multiple fin assemblies are merged with a common support structure and thermal conduction path, integrating several heat dissipation functions into a unified device. This consolidation achieves effective multi-directional heat dissipation while avoiding the complexity of completely separate heat dissipation systems.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Different fin assemblies are positioned to address specific local heat generation areas on the processor, with each fin assembly optimized for its particular thermal zone. This localized approach improves temperature control efficiency without requiring a uniformly complex structure throughout the entire device.

Inventive Principle:

Solution Approach 1:

The heat dissipation device utilizes natural convection currents created by the multi-directional fin structure, allowing airflow patterns to dynamically adapt to thermal gradients without requiring high-speed forced airflow. This reduces the energy needed to drive air movement while maintaining effective heat dissipation.

Inventive Principle:

Solution Approach 2:

The fin assembly structure is designed to generate its own airflow through natural buoyancy-driven convection, where heated air naturally rises through and around the fins without external power input. This self-servicing mechanism reduces dependency on high-power cooling fans while maintaining heat dissipation effectiveness.
