Solution Overview

Problem

Existing fluid distribution modules in thermal management systems experience turbulence and pressure increases at the interface between fluid inlets/outlets and channels, leading to erosion and contamination, particularly when fluids turn 90°, which affects performance and noise levels.

Innovation Solution

A fluid distribution module design featuring a first plate with heat transfer fluid passages and a second plate with concave pockets opposite the passages, allowing fluids to turn smoothly and reducing turbulence, with the passages forming angles between 70° and 110° and pockets with radii between 20 mm and 50 mm, minimizing energy consumption and noise.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the fluid inlet/outlet is arranged perpendicular to the channel (90° angle), then the compact design is achieved, but turbulence and pressure increase occur at the interface

Engineering Contradiction:
Improvemodule compactnessVSAvoidturbulence and pressure increase
Core Design Contradiction:
Volume of moving objectVSObject-generated harmful factors

Solution Approach 1:

The invention introduces a curved transition zone at the interface between the fluid inlet/outlet and the channel, replacing the sharp 90° angle with a gradual curved path. This curvature allows the fluid to turn smoothly without abrupt directional changes, thereby reducing turbulence and pressure increase while maintaining the compact perpendicular arrangement of inlet/outlet relative to the channel

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Volume of moving object

If the fluid turns 90° at the interface, then the space is efficiently utilized, but erosion and contamination are generated

Engineering Contradiction:
Improvespace utilizationVSAvoiderosion and contamination
Core Design Contradiction:
Volume of moving objectVSObject-generated harmful factors

Solution Approach 1:

The curved transition zone replaces the sharp 90° turn, allowing fluid to follow a smooth curved path. This eliminates abrupt flow direction changes that cause erosion and contamination, while the inlet/outlet remain efficiently positioned perpendicular to the channel for compact space utilization

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Object-generated harmful factors

If smooth flow is achieved by reducing the turn angle, then turbulence is reduced, but the module size increases

Engineering Contradiction:
Improveturbulence reductionVSAvoidmodule size
Core Design Contradiction:
Object-generated harmful factorsVSVolume of moving object

Solution Approach 1:

The curved transition zone provides smooth flow progression without requiring a reduced turn angle. The curvature allows the fluid to gradually change direction along an arc, reducing turbulence while maintaining the compact 90° perpendicular arrangement of inlet/outlet to the channel, thus avoiding increased module size

Inventive Principle:
Principle #14Spheroidality (Curvature)
