Solution Overview

Problem

Existing adapter elements for connecting electronic components to heat sink elements have limitations in cooling capacity due to the distance between web elements, which affects the efficiency of heat dissipation.

Innovation Solution

The adapter element features a design with first and second web elements arranged close together, typically less than 350 μm apart, allowing for a larger connection surface and improved heat dissipation by machining methods like sawing, using materials such as copper and ceramics, and bonding techniques like DCB or active soldering.

Solution Approach 1:

The patent applies parameter changes by optimizing the distance between web elements to a specific range (100-300 μm, preferably 125-200 μm). This quantitative parameter optimization resolves the contradiction by establishing a precise geometric parameter that maximizes cooling efficiency while remaining manufacturable through advanced fabrication techniques.

Solution Approach 1:

The adapter element is segmented into multiple thin web elements arranged in a comb-like structure. This segmentation increases the total connection surface area between the electronic component and heat sink while maintaining electrical insulation. The segmented design resolves the contradiction by distributing the connection function across multiple discrete elements rather than requiring a single complex structure.
