Solution Overview

Problem

Existing energy storage apparatuses face challenges in maintaining efficient heat dissipation, leading to reduced operational efficiency and increased risk of device failure due to heat buildup during charging and discharging processes.

Innovation Solution

The energy storage apparatus is designed with air inlets and outlets positioned on opposite sides of the cabinet body, allowing airflow to flow from one side to the other, with the heat dissipation device located above the energy storage members, enhancing heat exchange efficiency and reducing the risk of foreign matter ingress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the air inlet and air outlet are positioned on the same side of the cabinet body, then the structure is simpler and occupies less space, but the heat dissipation stability deteriorates due to high-temperature air recirculation

Engineering Contradiction:
Improvestructural complexityVSAvoidheat dissipation stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent transitions from a single-side air inlet/outlet configuration to a multi-directional configuration where the air inlet is positioned on one side wall and the air outlet on an opposite or adjacent side wall of the cabinet body. This spatial dimensionality change prevents hot air recirculation by ensuring discharged air does not re-enter the inlet, thereby improving heat dissipation stability without significantly increasing structural complexity.

Principle #17Another dimension (Dimensionality change)

2Reliability

If the air inlet and air outlet are positioned on opposite sides of the cabinet body, then the heat dissipation stability improves, but the cabinet body occupies more space

Engineering Contradiction:
Improveheat dissipation stabilityVSAvoidcabinet body area
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent applies local quality by positioning the air inlet and air outlet at specific locations on different side walls of the cabinet body, optimizing their vertical and horizontal positions to achieve effective heat dissipation. The air inlet is positioned at a lower height while the air outlet is positioned at a higher height on an opposite or adjacent side, creating an efficient airflow path that maximizes heat dissipation stability while minimizing the overall cabinet footprint.

Inventive Principle:
Principle #3Local quality

3Object-affected harmful factors

If the air inlet is positioned at a higher location, then foreign matter ingress is reduced, but heat exchange efficiency with the heat dissipation device deteriorates

Engineering Contradiction:
Improveforeign matter ingressVSAvoidheat exchange efficiency
Core Design Contradiction:
Object-affected harmful factorsVSUse of energy by moving object

Solution Approach 1:

The patent utilizes vertical dimensionality by positioning the air inlet at a lower height and the air outlet at a higher height on the cabinet body. This vertical arrangement allows the air inlet to be positioned where it can effectively draw in ambient air for heat exchange with the heat dissipation device, while the elevated air outlet position naturally reduces foreign matter ingress. The vertical separation creates an efficient upward airflow path that simultaneously optimizes both heat exchange efficiency and contamination prevention.
