The base plate and the array of pin fins are divided into a first heat sink region corresponding to the hot spot region of the heating element, and a second heat sink region corresponding to the background region of the heating element. The first heat sink region is made of a material having a higher thermal conductivity than a material of which the second heat sink region is made."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Composite pin fin heat sink with improved heat dissipation performance","description":"A composite pin fin heat sink configured to dissipate heat generated by a heating element including a background region and a hot spot region having a higher temperature than the background region whi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11252842","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
