Solution Overview

Problem

Existing energy storage cabinets face reduced heat-dissipation effects due to hot air reflux, which affects the stability and safety of the energy storage converter, despite having air inlets and outlets on the cabinet sides.

Innovation Solution

The implementation of a baffle in the converter chamber separates it into cold and hot air cavities, ensuring cold air directly enters the heat-dissipation duct and hot air is directly expelled, preventing reflux and enhancing the heat-dissipation effect.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If air inlet and air outlet are provided on the cabinet sides for heat dissipation, then the energy storage converter can be cooled, but hot air reflux occurs reducing heat-dissipation effectiveness

Engineering Contradiction:
Improveambient temperature of energy storage converterVSAvoidheat-dissipation effect
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The converter chamber is segmented into a cold air cavity and a hot air cavity by the baffle. The baffle divides the single chamber into two distinct regions, allowing separate management of cold and hot air flows. This segmentation prevents hot air from mixing with cold air and refluxing back to the energy storage converter, thereby improving heat-dissipation effectiveness while maintaining lower ambient temperature around the converter.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The baffle acts as an intermediary structure between the cold air inlet and hot air outlet. It mediates the airflow paths by directing cold air through the heat-dissipation duct to the converter, and channeling hot air away from the converter through a separate path. This intermediary structure ensures that hot air does not directly contact or reflux to the converter, resolving the contradiction between cooling effectiveness and preventing hot air recirculation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If cold air is blown into the air inlet to cool the energy storage converter, then the converter operates stably, but hot air flows out and may reflux affecting cooling efficiency

Engineering Contradiction:
Improveoperation stability of energy storage converterVSAvoidcooling efficiency
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

By segmenting the converter chamber into cold and hot air cavities, the system maintains stable cooling of the converter while preventing energy loss through hot air reflux. The segmentation ensures that the cold air flow path remains dedicated and efficient, and hot air is channeled separately away from the converter, preserving cooling efficiency while maintaining operation stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The baffle serves as an intermediary that separates the cold air intake path from the hot air exhaust path. It ensures that cold air efficiently reaches the converter for stable operation, while simultaneously directing hot air away from the converter to prevent energy loss through reflux. This mediation resolves the contradiction between maintaining stable operation and preserving cooling efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If a baffle is added to separate cold and hot air cavities, then heat-dissipation effect is enhanced, but device complexity increases

Engineering Contradiction:
Improveheat-dissipation effectVSAvoidconverter chamber structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The baffle implements a simple segmentation of the converter chamber into two cavities. This segmentation enhances heat-dissipation effect by preventing hot air reflux, while the baffle itself is a relatively simple structural element that can be easily integrated into the existing chamber design. The segmentation approach achieves improved reliability without requiring complex multi-component systems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The baffle acts as a single intermediary component that achieves the separation function. Rather than requiring multiple complex mechanisms or active control systems, a simple baffle structure mediates between cold and hot air flows, enhancing heat-dissipation effect while adding minimal structural complexity to the converter chamber.

Inventive Principle:
Principle #24Intermediary (Mediator)
