Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power supply devices for ozone generators above 100kW are large, heavy, and complex, with high heat density, requiring separate housings for components and increased size due to safety insulation needs, complicating maintenance and operation.
Innovation Solution
A compact power supply device design where a transformer, inverter, and reactor are housed together, with a flat heat exchanger at the bottom, a protection panel for high voltage isolation, and a fan positioned inside the front door to facilitate easy maintenance and cooling, reducing size and complexity while ensuring safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transformer, inverter and reactor are disposed in different housings, then safety insulation distance is secured, but device size is increased and configuration is complicated
Solution Approach 1:
The patent combines transformer, inverter and reactor into a single integrated housing, eliminating the need for separate housings while maintaining safety insulation through internal design features such as insulation structures and spatial arrangement within the unified housing
Solution Approach 2:
The patent uses vertical spatial arrangement within the housing, placing components at different heights and levels to achieve both compact integration and sufficient insulation distance, transforming the problem from horizontal separation to vertical arrangement
2Temperature
If separate heat exchangers and fans are provided for each component, then cooling performance is sufficient, but device size is increased
Solution Approach 1:
The patent uses a shared cooling system where a common heat exchanger and fan serve multiple components (transformer, inverter, reactor), consolidating what would otherwise require separate cooling systems and reducing overall device size
Solution Approach 2:
The heat exchanger and fan are designed as universal cooling components that can cool multiple different components simultaneously, achieving multi-functionality and reducing the total number of cooling devices needed
3Reliability
If partition plate for preventing electric shock is disposed, then safety is improved, but size of device is increased
Solution Approach 1:
The patent applies insulation and safety measures only where high voltage is present, using targeted insulation structures and spatial arrangement rather than universal separation, thereby maintaining safety while minimizing the volume occupied by safety features

AI summary
A power supply device for an ozone generator, which supplies electric power to the ozone generator, is configured such that: a transformer, an inverter, and a reactor are disposed inside of one housing; a flat heat exchanger which cools passing air with cooling water is disposed at a lower part inside of the housing; the transformer and the inverter are disposed above the heat exchanger; the reactor is disposed above the transformer and the inverter; a protection panel is disposed further toward the front side of the housing than the transformer and the inverter by being separated from a front door of the housing; and cooling air is circulated in the housing by means of a fan that disposed at a position inside of the front door.
