Electrical Equipment Casing with Integrated Reactor Housing Dent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical equipment casings with integrated reactors face a trade-off between enhanced heat dissipation and size reduction, as increased heat dissipation often requires larger dimensions due to the addition of radiator fins.
Innovation Solution
The electrical equipment casing incorporates a heat sink with a reactor housing dent and radiator fins positioned around the outer circumference, allowing the reactor to be housed in a way that maximizes contact with the heat sink, enhancing heat dissipation while minimizing the casing's size by utilizing the fins efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If radiator fins are added to enhance heat dissipation, then heat releasing efficiency is improved, but the overall casing size increases
Solution Approach 1:
The reactor housing portion and heat sink are merged into a single integrated structure. The reactor housing dent is formed directly on the heat sink, eliminating the need for separate components. This integration allows the radiator fins to serve dual purposes: cooling the heat sink while also providing the housing structure for the reactor, thereby reducing overall casing size while maintaining effective heat dissipation
Solution Approach 2:
The reactor housing dent is formed by utilizing the thickness dimension of the heat sink. By creating a recessed area within the heat sink's volume rather than adding external structures, the design efficiently uses the existing three-dimensional space. The radiator fins extend from the heat sink surface surrounding this dent, maximizing heat dissipation surface area without increasing the overall footprint of the casing

AI summary
An electrical equipment casing includes a circuit board on which many electrical parts are mounted and a heat sink to which the circuit board is fixed. The heat sink is provided with a reactor housing dent that opens in a surface on which the circuit board is placed and radiator fins that reach a bottom portion of the reactor housing dent on a surface opposite to the surface on which the circuit board is placed at a position surrounding an outer circumference of the reactor housing dent. The reactor is housed in the reactor housing dent and a terminal thereof is electrically connected to the circuit board. This structure of the electrical equipment casing can contribute to an achievement of both of a size reduction of the overall casing and enhanced heat dissipation of the reactor.
