Solution Overview
Problem
Existing graphics card heat dissipation mechanisms are inefficient in managing the substantial thermal energy generated by high-performance GPUs and memory chips, particularly for sophisticated graphics and games, as they often reach the maximum capacity of existing cooling systems.
Innovation Solution
A dual heat dissipation mechanism is implemented, comprising a fan and heat sink with radiators for air-based cooling, and a metal block with tubing and a radiator using coolant circulation for additional thermal energy transfer, along with a pump and directed airflow to enhance heat removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a single fan and heat sink mechanism is used, then the device complexity is low, but the heat dissipation capacity is insufficient for high-performance GPUs
Solution Approach 1:
The cooling system is divided into two independent subassemblies: a lower heat dissipating subassembly with a fan and heat sink, and an upper heat dissipating subassembly with a metal block, tubing, and radiator. Each subassembly handles a portion of the thermal load, allowing the system to manage high heat generation without requiring a single overly complex cooling mechanism.
Solution Approach 2:
A metal block with internal tubing acts as an intermediary heat transfer component. The metal block receives thermal energy from the GPU and transfers it to coolant circulating through the tubing, which then dissipates heat through the radiator. This intermediary mechanism enables efficient heat removal without direct fan-to-GPU contact.
2Temperature
If existing heat dissipation mechanisms are used, then the manufacturing cost is low, but they reach maximum capacity and cannot handle sophisticated graphics processing heat
Solution Approach 1:
The patent merges two different heat dissipation approaches into a single integrated system: air-based cooling (fan and heat sink) and coolant-based cooling (metal block with tubing and radiator). The two subassemblies work together to handle the total thermal load, combining the advantages of both cooling methods to achieve superior heat removal efficiency.
Solution Approach 2:
The upper heat dissipating subassembly utilizes hydraulics by circulating coolant through tubing embedded in the metal block. The coolant absorbs thermal energy from the GPU through conduction and transports it to the radiator, where heat is dissipated to the surrounding air. This hydraulic heat transfer mechanism significantly enhances the system's thermal management capability.

Implementation Method 3
A pump, connected to the pipe and tubing, circulates coolant therethrough so that the thermal energy conducted to the metal block is sunk to the baffles of the radiator
Implementation Method 4
A pump, connected to the inlet end of the tubing and the exit end of the pipe, circulates coolant through the pipe and tubing
Implementation Method 5
a fan unit that generates and directs an air flow toward the metal block and radiator to remove heat therefrom

AI summary
A cooling mechanism to dissipate thermal energy generated by the active electronic components of a graphics card assembly. A mechanism includes a radiator and a metal block that is thermally coupled to the active electronic components and that has a tubing therewithin. The radiator includes a pipe and baffles attached to the pipe, where one end of the pipe is connected to one end of the tubing. A pump, connected to the other ends of the tubing and pipe, circulates coolant through the pipe and tubing to transfer thermal energy from the metal block to the radiator. The mechanism also includes a fan unit to generate and direct an air flow toward the radiator and metal block, where the air flow removes the thermal energy from the radiator and metal block.
