Engineering Contradiction Analysis
1Power
If traditional heat pipe structures are used with straight extensions, then manufacturing is simple, but cooling capability is insufficient for high processing rate integrated circuits
Solution Approach 1:
The heat pipe joint is designed with a curved configuration instead of a straight connection, allowing air to flow around it efficiently. This curved structure enhances cooling capability by enabling better airflow patterns around the joint area while maintaining manufacturing feasibility through standard bending processes.
Solution Approach 2:
The invention adds a second extension to the heat pipe that is spaced from the first extension in the second direction (perpendicular to the first direction). This creates a three-dimensional heat dissipation structure with multiple extensions arranged in different spatial dimensions, increasing the effective heat radiation area and improving cooling performance.

If heat pipes with single straight extension are used, then structure is simple, but heat radiation area is limited
Solution Approach 1:
The heat pipe structure transitions from a single straight extension to multiple extensions spaced in different directions. The first extension extends in the first direction while the second extension is spaced from the first extension in the second direction (perpendicular direction), creating a multi-dimensional heat radiation structure that significantly increases the effective heat dissipation area.
Solution Approach 2:
The heat pipe is divided into multiple segments including a first extension, a curved joint, and a second extension spaced from the first extension. This segmentation allows each part to contribute to heat radiation from different locations and angles, maximizing the overall heat radiation area while maintaining structural integrity.

If joints are positioned where airflow is blocked, then manufacturing is easier, but cooling efficiency decreases due to unwanted radiation
Solution Approach 1:
The curved joint design allows air to flow smoothly around it rather than being blocked. The curvature creates an aerodynamic shape that maintains airflow velocity and prevents dead zones, thereby improving cooling efficiency while avoiding the need for complex positioning requirements.
Solution Approach 2:
The joint is specifically designed with curved geometry at the location where it intersects with airflow paths. This local curvature feature addresses the airflow blocking issue at the critical joint position without requiring changes to the overall heat pipe structure or positioning, maintaining ease of manufacture while improving cooling efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design significantly increases the cooling capability of the heat sink by effectively radiating heat through air flow around the joints, reducing physical interference and improving manufacturing efficiency, thus addressing the limitations of existing heat sink technologies.
Implementation Method 1
Heat pipes are connected to the heat receiver for spreading heat received by the heat receiver over a wide area of the metal plate and the fins
Implementation Method 2
The heat sink and the electronic device are able to provide an increased cooling capability as they can radiate heat from the second fin via air flowing around the position of the joint

AI summary
A heat sink includes a plurality of fins arrayed in a first direction, and a heat pipe having a first extension extending in the first direction. A second direction extends perpendicularly to the first direction, a third direction extends perpendicularly to the first direction and the second direction, and when the heat pipe is viewed in the third direction, the heat pipe has a second extension spaced from the first extension in the second direction and extending in the first direction, and a joint which interconnects the first extension and the second extension and which is curved. The fins include a plurality of first fins arrayed along the first extension and the second extension and a second fin disposed around a position of the joint.
