Liquid Cooling Device with Nested Tanks for Compact Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid cooling systems face challenges in achieving high heat dissipation performance while maintaining a compact size, often resulting in turbulence due to the interaction of high and low-temperature coolants, which affects their efficiency in dissipating heat from expansion cards and other electronic components.
Innovation Solution
The proposed liquid cooling system incorporates a configuration with multiple tanks and a channel structure that ensures non-overlapping orthogonal projections of the tanks, maintaining a larger distance between the second tank and the first tank compared to the third tank, and positioning the third tank within a recess or gap, preventing the convergence of high and low-temperature coolants and allowing for a compact arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the liquid cooling system is reduced in size to adapt to compact internal arrangement, then the volume is reduced, but the heat dissipation performance deteriorates
Solution Approach 1:
The patent places the third tank inside a recess of the channel structure, effectively nesting one component within another. This allows the cooling system to maintain multiple tanks for adequate heat dissipation while reducing the overall external volume of the system, resolving the contradiction between compact size and heat dissipation performance.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by positioning tanks at different heights and depths rather than simply expanding in one direction. The first tank is positioned at a first height, the second tank at a second height, and the third tank within a recess, creating efficient use of vertical and depth dimensions to maintain performance while reducing footprint.
2Power
If multiple tanks are used to improve heat dissipation performance, then the heat dissipation performance is improved, but the device complexity increases
Solution Approach 1:
The patent integrates the third tank within a recess of the channel structure rather than as a separate external component. This merging of the tank with the channel structure reduces the number of discrete parts and simplifies assembly, thereby reducing device complexity while still providing the heat dissipation benefits of multiple tanks.
Solution Approach 2:
The channel structure serves multiple functions: it acts as a flow channel for coolant and simultaneously provides a recess to house the third tank. This multi-functionality reduces the need for separate structural components, simplifying the overall device complexity while maintaining effective heat dissipation through multiple tanks.
3Volume of moving object
If tanks are positioned close together to reduce volume, then the volume is reduced, but turbulence occurs due to interaction of high and low-temperature coolants
Solution Approach 1:
The patent positions the tanks at different heights (first tank at first height, second tank at second height) and connects them through channels, creating a gravity-assisted flow path that maintains stable temperature gradients. This vertical arrangement with controlled connections prevents random mixing of high and low-temperature coolants, maintaining flow stability while keeping the device compact.
Solution Approach 2:
The channel structure acts as an intermediary that controls the flow path between tanks of different temperatures. By designing specific connection channels between the first tank, second tank, and third tank, the system manages the interaction between high and low-temperature coolants, preventing turbulence while maintaining compact positioning.
