Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling fins are provided in the heat dissipation member, then cooling performance is improved, but pressure loss increases and manufacturing cost increases
Solution Approach 1:
The invention extracts and eliminates the cooling fins from the heat dissipation member, replacing them with a different cooling mechanism. The protruding portion from the base portion and recessed portion from the heat dissipation assembly create cooling channels that achieve heat dissipation without traditional fins, thereby reducing pressure loss while maintaining cooling performance.
Solution Approach 2:
Instead of adding cooling fins to enhance cooling, the invention inverts the approach by creating cooling channels through protruding and recessed portions that redirect refrigerant flow. This inverted design achieves cooling through flow path optimization rather than surface area expansion, reducing the harmful pressure loss effect.
2Temperature
If cooling fins are provided in the heat dissipation member, then cooling performance is improved, but manufacturing cost increases
Solution Approach 1:
The invention merges the cooling function with the structural components themselves. The protruding portion from the base portion and recessed portion from the heat dissipation assembly are integrated into the existing structure, eliminating the need for separate cooling fins and reducing manufacturing steps, tooling requirements, and assembly operations, thereby lowering manufacturing cost.
Solution Approach 2:
The protruding and recessed portions serve multiple functions: they create cooling channels for heat dissipation, provide structural support, and define refrigerant flow paths. This multi-functionality eliminates the need for dedicated cooling fins, simplifying manufacturing and reducing costs while maintaining cooling performance.
3Area of stationary object
If cooling fins are provided in the heat dissipation member, then heat dissipation area is increased, but device complexity increases
Solution Approach 1:
The invention transitions from two-dimensional fin surfaces to three-dimensional cooling channels formed by protruding and recessed portions. This dimensional change creates effective heat dissipation pathways through volume rather than surface area, achieving cooling performance without the structural complexity of traditional fin arrays.

AI summary
A liquid cooling jacket includes a base portion and a protruding portion protruding from an end surface on a first side in a third direction of the base portion in the third direction. A heat dissipation assembly includes a recessed portion recessed from an end surface on a second side in the third direction. A refrigerant flow path having a width in the second direction is between the end surface on the first side in the third direction of the base portion and the end surface on the second side in the third direction of the heat dissipation assembly. A position of the recessed portion coincides with a position of the protruding portion. An end portion of the protruding portion is farther on the second side in the first direction than an end portion on the first side in the first direction of the recessed portion.
