Series Pump Unit for Liquid Cooling Head Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid cooling systems for electronic and electric elements face challenges in efficiently managing increased heat dissipation requirements, often necessitating larger and heavier pumps, which increase costs, installation time, and risk of leakage, especially when the required head exceeds pump specifications.
Innovation Solution
A liquid cooling multi-pumping unit is designed with first and second pumps arranged in series, each with a plurality of curved blades, driven by motor assemblies, forming a single main body to increase head pressure and flow rate while reducing energy consumption and minimizing risks through lower operating speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If a much bigger and heavier pump is employed to meet required head beyond pump specifications, then head pressure is improved, but weight increases
Solution Approach 1:
The pump system is segmented into multiple smaller pump units (first pump unit, second pump unit, etc.) that operate in parallel. Each pump unit handles a portion of the total flow requirement, allowing the system to achieve the required head pressure without needing a single oversized pump. This segmentation enables using lighter, more manageable pump units while collectively meeting the performance requirements.
2Stress or pressure
If a much bigger and heavier pump is employed to meet required head beyond pump specifications, then head pressure is improved, but cost increases
Solution Approach 1:
The system uses multiple standard-sized pump units instead of one custom oversized pump. This allows using off-the-shelf components with established manufacturing processes, reducing development costs and enabling modular assembly. The parallel configuration achieves required head pressure through flow distribution rather than pressure multiplication, using cost-effective standard pumps rather than expensive custom-engineered high-pressure pumps.
3Stress or pressure
If a much bigger and heavier pump is employed to meet required head beyond pump specifications, then head pressure is improved, but installation time increases
Solution Approach 1:
The pump system is divided into independent modular units that can be installed separately and then connected in parallel. This modular approach allows for simpler piping connections, independent mounting locations, and easier integration into existing systems. The standardized interfaces and parallel configuration reduce installation complexity and time compared to installing a single large complex pump system.
4Stress or pressure
If a much bigger and heavier pump is employed to meet required head beyond pump specifications, then head pressure is improved, but risk of leakage increases
Solution Approach 1:
The system distributes the fluid handling function across multiple independent pump units with separate sealing systems. This segmentation means that a sealing failure in one unit does not compromise the entire system, and each pump operates at lower individual pressures and flow rates, reducing stress on seals and connections. The parallel configuration provides inherent redundancy against leakage failures.
5Stress or pressure
If a much bigger and heavier pump is employed to meet required head beyond pump specifications, then head pressure is improved, but total area requirements increase
Solution Approach 1:
Multiple compact pump units can be arranged in a distributed parallel configuration that utilizes available space more efficiently than a single large pump. The modular units can be mounted on different platforms, walls, or racks, reducing the concentrated footprint. The independent piping runs for each pump unit can be routed through existing conduits and spaces, minimizing additional area requirements.

AI summary
A liquid cooling multi-pumping unit comprising a main body and first and second pumps arranged in series is provided. During operation, cooling fluid is sucked via a cooling fluid inlet into a first fluid chamber and then into a first central chamber opening to a plurality of curved blades of a first impeller assembled in a first pump chamber. From there, the cooling fluid travels and is sucked through a fluid distribution channel into a second fluid chamber and then into a second central chamber opening to a plurality of curved blades of a second impeller assembled in a second pump chamber, before exiting through a fluid outlet. The series arrangement of the first and second pumps increases head pressure, and provides sufficient liquid flow in the case where one liquid cooling pump fails. Additionally, lower energy consumption is achieved due to the lower operating speeds required.
