Solution Overview

Problem

Satellites face challenges in managing heat generated by electronic components, which can lead to unacceptable temperature rises due to the complexity and mass of existing thermal dissipation systems, particularly in space environments where heat management is more difficult than on Earth.

Innovation Solution

A three-dimensional passive thermal radiator structure is implemented, using embedded heat pipes to thermally and structurally couple radiator panels, reducing the need for external thermal coupling and minimizing additional parts, thereby enhancing thermal efficiency and manufacturing simplicity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If traditional thermal dissipation systems are used in satellites, then heat can be dissipated, but the mass and complexity of the system increase

Engineering Contradiction:
Improveheat dissipation capabilityVSAvoidthermal dissipation system complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent merges the thermal dissipation function with the structural support function by integrating heat pipes directly into the radiator panel structure. The heat pipes are embedded within the panel thickness, eliminating the need for separate external thermal coupling components and reducing overall system complexity while maintaining effective heat dissipation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The radiator panel structure serves multiple functions simultaneously: it provides structural support for the satellite, acts as a thermal dissipation surface, and incorporates heat pipes for heat transport. This multi-functionality reduces the number of separate components needed, thereby reducing mass and complexity while maintaining thermal management capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 1:

By combining the heat pipe with the radiator panel structure, the patent eliminates the need for separate external thermal coupling components. The heat pipes are embedded within the panel, reducing the total number of parts and thereby reducing the overall mass of the thermal dissipation system while maintaining effective heat removal capability.

Inventive Principle:
Principle #5Merging (Combining)

3Temperature

If external thermal coupling is used between radiator panels, then thermal connection is achieved, but additional parts and assembly steps are required

Engineering Contradiction:

Solution Approach 1:

The patent integrates the thermal coupling function directly into the radiator panel structure by embedding heat pipes within the panel thickness. This eliminates the need for separate external thermal coupling components and reduces assembly steps, as the heat pipes are already incorporated during panel manufacturing rather than requiring post-assembly operations.

Inventive Principle:
Principle #5Merging (Combining)
