Solution Overview

Problem

Conventional thermal modules face a weak connection between the base seat and heat pipe, leading to detachment under axial external forces, which limits heat dissipation efficiency and product quality, especially with multi-core CPUs.

Innovation Solution

A thermal module assembling structure featuring a base seat with a recessed channel and protrusion sections, and a heat pipe with corresponding insertion recesses, where the protrusion sections are tightly fitted and connected, enhancing the connection strength and preventing detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If press fit method is used to connect heat pipe with base seat, then the connection process is simple, but the connection strength is poor and detachment occurs under axial force

Engineering Contradiction:

Improveconnection process simplicityVSAvoidconnection strength

Core Design Contradiction:

Ease of manufactureVSStrength

Solution Approach 1:

The patent changes the connection from a single axial dimension to multiple dimensions by adding protrusion sections that extend radially from the channel walls. These protrusions engage with corresponding recesses on the heat pipe, creating a multi-directional mechanical interlock that prevents axial detachment while maintaining manufacturing simplicity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The connection interface is segmented into multiple engagement points through the protrusion sections distributed along the channel. Instead of relying on a single press-fit interface, the connection is divided into multiple discrete protrusion-recess pairs that collectively provide enhanced strength and resistance to axial forces.

Inventive Principle:

Principle #1Segmentation

2Strength

If welding materials are used to enhance connection strength, then the connection strength improves, but the cost increases

Engineering Contradiction:

Improveconnection strengthVSAvoidmaterial cost

Core Design Contradiction:

StrengthVSQuantity of substance

Solution Approach 1:

The base seat structure itself provides the strengthening function through its protrusion sections, eliminating the need for external welding materials. The geometric features of the base seat (protrusions and channels) directly create the strong mechanical connection without requiring additional substances, making the structure self-sufficient for connection enhancement.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent extracts the connection-strengthening function from external welding materials and integrates it directly into the base seat geometry. By removing the need for separate welding materials and incorporating the strengthening mechanism into the base seat's own structure, the solution reduces material cost while maintaining connection strength.

Inventive Principle:

Principle #2Taking out (Extraction)
