Solution Overview
Problem
Existing explosion-protected housings face challenges in effectively cooling high-power electronic and electric components without increasing costs or space, as traditional cooling methods like narrow gaps or external cooling fins are insufficient for efficient heat dissipation.
Innovation Solution
Incorporating closed cooling pipes within the housing walls that allow for the flow of a cooling fluid, which can be arranged in various configurations and connected to fluid-moving devices for enhanced cooling efficiency, without compromising explosion protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional cooling methods like narrow gaps or external cooling fins are used, then the housing structure is simple, but the cooling efficiency is insufficient for high-power components
Solution Approach 1:
The patent applies hydraulic cooling by integrating closed cooling pipes within the housing walls that allow liquid cooling fluid to flow through them. This hydraulic system efficiently removes heat from high-power electronic and electric components while maintaining explosion protection, resolving the contradiction between cooling efficiency and system complexity.
2Temperature
If the housing size is increased to provide sufficient cooling space, then cooling capacity is improved, but costs and space requirements increase
Solution Approach 1:
The patent embeds cooling pipes within the existing housing walls, nesting the cooling system inside the structural boundaries. This allows efficient cooling of high-power components without increasing the overall housing volume, as the cooling infrastructure is integrated into the wall structure rather than adding external bulk.
Solution Approach 2:
The patent utilizes the wall thickness dimension by running cooling pipes through the walls in various configurations (parallel, spiral, U-shaped, meandering). This three-dimensional utilization of existing wall space provides enhanced cooling capacity without increasing the external dimensions of the housing.
3Temperature
If additional cooling means are added to handle high power components, then cooling performance is improved, but costs increase
Solution Approach 1:
The housing walls serve dual functions: structural containment and thermal management. By integrating cooling pipes within the walls, the walls simultaneously provide mechanical strength and heat dissipation pathways, eliminating the need for separate external cooling structures and reducing overall manufacturing costs.
Solution Approach 2:
The patent merges the cooling system with the housing structure by embedding cooling pipes within the walls. This integration combines what would traditionally be separate components (housing and cooling system) into a unified structure, reducing part count, assembly complexity, and manufacturing costs while maintaining effective cooling performance.

AI summary
An explosion-protected housing, such as a switchboard, junction box, distribution box, or the like, comprising sidewalls, one back or bottom wall connecting the sidewalls, and a lid or door wall part closing a housing opening. In the housing interior, electronic and/or electric components are arranged, wherein the housing comprises a cooling device. To allow the cooling of a plurality of electronic and/or electric components in the housing interior in a simple way and without higher costs and requiring more space, at least one cooling pipe as a cooling device is provided in at least one wall or a wall part and is closed to the housing interior and flowed through by a cooling fluid.
