Solution Overview

Problem

Existing hydrogen generators face challenges in efficiently dissipating heat generated during the electrolysis process, leading to thermal damage and increased size due to the need for longer radiator columns, which complicates maintenance and assembly.

Innovation Solution

A radiator with a spiral structure and delay structure is integrated into the hydrogen generator, increasing the path length for heat dissipation within a limited space, forming a heat dissipation channel that enhances contact between electrolyzed water and the environment without requiring additional space or replacing the entire radiator.

VSEngineering Contradiction Analysis

1Productivity

If the length of the radiator column is increased to improve heat dissipation efficiency, then the heat dissipation efficiency is improved, but the size of the hydrogen generator increases and additional space is needed

Engineering Contradiction:

Improveheat dissipation efficiencyVSAvoidsize of hydrogen generator

Core Design Contradiction:

ProductivityVSVolume of moving object

Solution Approach 1:

The spiral structure is nested within the column structure, with the spiral channel formed by the bent portion of the column. This allows the heat dissipation path to be folded back on itself, increasing the effective heat dissipation surface area within the same spatial footprint, thereby improving heat dissipation efficiency without increasing the overall size of the hydrogen generator.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The column structure transitions from a simple linear path to a three-dimensional spiral configuration. By utilizing the vertical and radial dimensions through the spiral bending, the heat dissipation path length is extended without proportionally increasing the horizontal space occupied, thus improving heat dissipation efficiency while maintaining a compact generator size.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Productivity

If the length of the radiator column is increased to improve heat dissipation efficiency, then the heat dissipation efficiency is improved, but the device complexity increases and maintenance becomes more difficult

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSEase of repair

Solution Approach 1:

The radiator is divided into modular components: the base with flow channel structure and the separate column structure with spiral bending. This segmentation allows the column to be independently removed and replaced if damaged, simplifying maintenance procedures while still achieving the desired heat dissipation efficiency through the spiral configuration.

Inventive Principle:

Principle #1Segmentation

3Temperature

If a fan is used to help heat dissipation of the electrolysis cell, then the heat dissipation is improved, but it is difficult to dissipate heat for a large area where heat is accumulated in the electrolyzed water

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The system uses hydraulic flow by circulating electrolyzed water through the column structure's internal channels. This forced liquid circulation through the spiral path enables efficient heat extraction from large areas of the electrolysis cell, overcoming the limitations of fan-based air cooling which cannot effectively dissipate heat over large areas where heat accumulates in the electrolyzed water.
