Solution Overview
Problem
Existing heat dissipation apparatuses for suspended electronic devices, such as projectors and indoor surveillance cameras, have limited heat dissipation effectiveness due to restricted fin height and airflow path design, which restricts the heat dissipation performance.
Innovation Solution
A heat dissipation apparatus featuring a base plate with guide fins and heat dissipation fins, where multiple heat dissipation fin groups are arranged with varying gaps from the base plate to enhance airflow flow rate and heat exchange, including the use of stopper fins and heat dissipation teeth to control airflow and improve heat dissipation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the heat dissipation apparatus is disposed near the ceiling, then the installation space is saved, but the fin height is limited and heat dissipation effect is reduced
Solution Approach 1:
The patent transforms the traditional vertical fin structure into a horizontal guide fin structure that extends along the base plate surface. This dimensional change allows the heat dissipation apparatus to maintain effective heat exchange area without requiring vertical height, thus solving the contradiction between limited installation space near ceiling and reduced heat dissipation effect.
Solution Approach 2:
The guide fins are disposed at intervals to form localized flow paths between adjacent fins. This local quality variation creates optimized airflow channels in different regions, allowing efficient heat dissipation within the constrained horizontal space without uniform structure throughout.
2Ease of manufacture
If uniform gap is maintained between base plate and heat dissipation fins, then manufacturing is simplified, but heat exchange efficiency is reduced in high temperature regions
Solution Approach 1:
The patent implements variable gap distances between the base plate and heat dissipation fins based on local temperature requirements. Regions with higher temperatures have larger gaps to enhance heat exchange efficiency, while other regions maintain smaller gaps. This local quality differentiation optimizes heat dissipation performance without excessive manufacturing complexity.

According to the heat dissipation apparatus of the present invention, guide fins (451) and a stopper fin (43) are disposed, so as to control an airflow direction when air flows, and further to prevent air with a relatively high temperature from accumulating in a central position of a base plate (21). In addition, a heat dissipation tooth is disposed, to improve an overall heat dissipation effect of the heat dissipation apparatus.
