ELECTRICAL DEVICE AND CASE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18402083 titled 'ELECTRICAL DEVICE AND CASE
Simplified Explanation: The patent application describes an electrical device with a cooling system that reduces stress concentration on welding portions.
- The device includes a case with a flow path for a cooling fluid.
- The flow path is elongated along a U shape between a bottom portion and a cover.
- The bottom portion and cover are joined by welding.
- The cover has protruding portions that reduce stress concentration on welding portions.
- The stress caused by the cooling fluid pressure acts on a distal end inside the U shape.
Potential Applications: 1. Industrial power control systems. 2. Electrical equipment in harsh environments. 3. Automotive electronics.
Problems Solved: 1. Stress concentration on welding portions. 2. Efficient cooling of electrical components. 3. Enhanced durability in challenging conditions.

Original Abstract Submitted
An electrical device such as a power control apparatus comprises a case and at least one electrical component accommodated in the case. The case has a flow path for a cooling fluid. The flow path is formed between a bottom portion and a cover. The flow path is elongated generally along a U shape. The bottom portion and the cover are joined by welding. The cover is formed with protruding portions protruding into the flow path. The protruding portions have shapes to reduce stress concentration on welding portions. A stress caused by a pressure of the cooling fluid may acts on a distal end formed inside of the U shape in a concentration manner.
