Liquid Cooling Plate Buffer Structure for Lower Flow Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid cooling devices face issues with flow resistance and increased system complexity due to the use of separate air and liquid cooling systems, and the design of cooling plates with larger diameters than connecting pipelines, leading to reduced cooling rates and increased manufacturing costs.
Innovation Solution
A cooling device with a cooling plate featuring a flow passage, buffer portions, and inclined buffer sections to reduce flow resistance, along with a horizontal arrangement of inlet and outlet pipes to minimize interference and maintain a thin design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an external liquid pipeline is directly connected to a cooling plate, then the cooling structure is simplified, but the liquid encounters flow resistance when flowing to the cooling plate
Solution Approach 1:
The patent introduces a buffer portion as an intermediary component between the liquid pipeline and the cooling plate. This buffer portion includes a buffer cavity that receives liquid from the pipeline and guides it into the flow passage, avoiding direct connection and reducing flow resistance and water hammer effects.
2Ease of manufacture
If the cooling plate has a diameter larger than the connecting pipeline, then the connection is simplified, but the thickness of the cooling plate increases
Solution Approach 1:
The patent resolves the dimensional conflict by changing the connection approach from planar (diameter-matching) to three-dimensional. The buffer portion extends in the thickness direction of the cooling plate, allowing the pipeline to connect to the buffer cavity rather than requiring the cooling plate diameter to match the pipeline diameter, thus maintaining thin plate design while simplifying connection.
3Speed
If liquid flows directly into the cooling plate from the pipeline, then the flow path is shortened, but the pressure fluctuation increases
Solution Approach 1:
The patent applies beforehand cushioning by designing a buffer portion with a buffer cavity that receives liquid from the pipeline before it enters the flow passage. This buffer cavity cushions pressure fluctuations and prevents water hammer effects, stabilizing the liquid flow before it reaches the cooling channels.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces flow resistance and power loss within the cooling plate while allowing for a thinner design, thereby saving manufacturing costs and enhancing cooling efficiency.
Implementation Method 1
the first buffer section is arranged close to the inlet buffer zone for buffering a pressure of the liquid flowing into the cooling plate; the second buffer section is arranged close to the outlet buffer zone for buffering a pressure of the liquid flowing out of the cooling plate
Implementation Method 2
in a length direction of the cooling device, the first buffer section is inclined to the cooling section relative to the water inlet section; in the length direction of the cooling device, the second buffer section is inclined to the cooling section relative to the water outlet section
Implementation Method 3
In recent years, liquid cooling has gradually been favored by the market and has become one of the mainstream developments in the field of electronic heat dissipation

AI summary
A cooling device includes a cooling plate and a buffer portion, a flow passage is formed in the cooling plate, and the buffer portion is arranged on the cooling plate. An inlet buffer zone and an outlet buffer portion are defined in the buffer portion, liquid flows into the flow passage through the inlet buffer zone and flows out of the flow passage through the outlet buffer portion. The liquid flows into the flow passage through the buffer portion, and the buffer portion can reduce the flow resistance of the liquid flowing into the flow passage. The liquid in the flow passage also flows out through the buffer portion, and the buffer portion can also reduce the flow resistance of the liquid flowing out of the flow passage.
