Solution Overview

Problem

Existing electric energy conversion apparatuses suffer from poor overall heat dissipation due to heated air flowing into the air outlet cover, which affects the heat dissipation effect of the top devices, leading to reduced reliability and practicability.

Innovation Solution

A heat dissipation assembly comprising a side cover with an air inlet and an air outlet cover, featuring a partition member that separates the air outlet space from the top of the apparatus, forming convection and heat dissipation passages to direct heated air away from the top, and incorporating a fan and radiator for enhanced heat transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the air outlet cover is arranged at the top of the electric energy conversion apparatus to increase the air outlet area, then the air outlet area is increased, but the heated air flows into the air outlet cover and affects the heat dissipation effect of the top devices

Engineering Contradiction:
Improveair outlet areaVSAvoidheat dissipation effect
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The air outlet cover is divided into a first air outlet cover and a second air outlet cover, with the partition plate separating them. The first air outlet cover handles air outlets at the top surface, while the second air outlet cover handles air outlets at the side surface. This segmentation prevents heated air from the side air outlets from directly contacting top devices, resolving the contradiction between increasing air outlet area and maintaining heat dissipation effectiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The partition plate acts as an intermediary element between the first and second air outlet covers. It physically separates the air flow paths, preventing the harmful interaction between heated air and top devices while allowing both air outlet covers to function independently. This intermediary structure enables the system to achieve both large air outlet area and effective heat dissipation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Area of stationary object

If the air outlet cover covers the top of the electric energy conversion apparatus, then the overall area of the air outlet cover can be increased, but the heated air can easily lead heat to the electric energy conversion apparatus at the top

Engineering Contradiction:
Improveair outlet cover areaVSAvoidheat transfer to top devices
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The air outlet cover is segmented into two distinct parts: the first air outlet cover for top surface air outlets and the second air outlet cover for side surface air outlets. This segmentation allows the overall air outlet cover area to be large while preventing heated air from side outlets from transferring heat to top devices through the partition plate separation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the air outlet cover are assigned different functions and properties. The first air outlet cover region is optimized for top surface air flow, while the second air outlet cover region is optimized for side surface air flow. The partition plate creates local separation, ensuring that each region performs its specific function without interfering with the other, thus preventing harmful heat transfer while maintaining large overall area.

Inventive Principle:
Principle #3Local quality
