Thin Pump Radial Channel Design for Hydraulic Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional small-sized pumps fail to provide sufficient hydraulic head, making them inadequate for maintaining the original function in lightweight and thin electronic products, where a balance between size and performance is crucial for effective heat dissipation.
Innovation Solution
A thin pump design featuring a casing with an impeller and stator, where the inlet and outlet channels are located on the outer surface rather than the top or bottom, allowing for a reduced thickness and enhanced hydraulic performance by utilizing a rotor with a magnetic component and a stator for efficient fluid flow and pressure generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the pump size is reduced to make electronic products thinner, then the thickness is reduced, but the hydraulic head becomes insufficient
Solution Approach 1:
The inlet and outlet channels are repositioned from the top/bottom surfaces to the outer radial surface of the casing. This dimensional reconfiguration allows the channels to be arranged radially rather than axially, enabling the pump to achieve sufficient hydraulic head without increasing axial thickness, thus resolving the contradiction between thin profile and hydraulic performance
2Volume of moving object
If conventional small-sized pumps are used, then the size is reduced, but the hydraulic head is insufficient
Solution Approach 1:
By relocating the inlet and outlet channels to the outer radial surface rather than the axial top/bottom surfaces, the pump achieves more efficient fluid flow paths. This dimensional change in channel arrangement allows small-sized pumps to generate sufficient hydraulic head by optimizing the radial flow configuration, resolving the contradiction between compact size and hydraulic performance
3Device complexity
If the inlet and outlet channels are located on the top or bottom surface, then the structure is simple, but the thickness increases
Solution Approach 1:
The inlet and outlet channels are moved from the axial top/bottom surfaces to the radial outer surface of the casing. This repositioning in a different spatial dimension allows the pump to maintain a thin axial profile while still providing adequate channel length for fluid flow, resolving the contradiction between structural simplicity and thickness reduction
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 design achieves a hydraulic head comparable to or greater than conventional axial flow pumps, while maintaining a compact size, thereby addressing the need for efficient heat dissipation in thin electronic products.
Implementation Method 1
The magnetic component is disposed on the impeller. The stator is disposed in the casing. The stator corresponds to the magnetic component of the rotor so as to drive the rotor to rotate with respect to the casing.

AI summary
A thin pump includes a casing, a rotor, and a stator. The casing has a bottom surface, an outer surface, a lower chamber, an upper chamber, an inlet channel, and an outlet channel. The outer surface is connected to the bottom surface. The upper chamber and the lower chamber connected to each other are surrounded by the outer surface. The upper chamber is located further away from the bottom surface than the lower chamber. The inlet channel and the outlet channel are located on the outer surface. The inlet channel and the outlet channel are respectively connected to the upper chamber and the lower chamber. The rotor includes an impeller rotatably disposed in the lower chamber and a magnetic component disposed on the impeller. The stator disposed in the casing corresponds to the magnetic component so as to drive the rotor to rotate with respect to the casing.
