Import Aluminum Extruded Heatsink — Buy in Bulk from Supplier in China

The DP-11 aluminum extruded heatsink measures 165.5 x 161.5 x 58.5 mm overall and weighs 335 g, making it a compact thermal solution for electronic assemblies where space and mass are constrained. It combines an aluminum fin array with embedded heat pipes and a copper base to spread and dissipate heat from concentrated sources. This construction targets medium-to-high thermal loads in enclosed or passively cooled systems where active fan solutions are impractical.

The aluminum alloy used in the fin stock provides standard corrosion resistance and moderate thermal conductivity typical of 6xxx series extrusions, while the copper base exploits higher conductivity at the critical interface. Heat pipes embedded within the extrusion transfer heat from the base to remote fin areas, improving effective dissipation without increasing footprint. The extrusion process produces consistent fin density and base flatness, though buyers should verify surface finish and flatness tolerance against their interface requirements. Typical extruded heatsinks in this size class achieve thermal resistances in the range of 0.3 to 0.6 K/W depending on airflow conditions, though supplier-confirmed performance curves are not stated.

Applications span LED lighting drivers, audio power amplifiers, industrial power electronics, and compact computing hardware where component-level fans are excluded for reliability or noise reasons. The 335 g mass suits board-level mounting without excessive mechanical loading. Beijing Deepcool Industries Co., Ltd. is located in Beijing's Shangdi International zone and holds an imported supplier tier with harbor trust status. Response rate and average response time data are not available, so direct contact is needed to confirm current lead time, MOQ, and available Incoterms.

Beijing Deepcool Industries Co., Ltd. operates from 12e Building 2, Yard 2, Shangdi International, Beijing 100085, China. The supplier is classified as an imported tier with harbor trust status, indicating a baseline verification level within the platform system. Both response rate and average response hours are recorded as zero, which means the supplier has not generated measurable response statistics through the platform. This does not indicate inactivity, but buyers should initiate direct enquiry and record response behaviour themselves.

The listing presents a single product, the DP-11 heatsink, with dimensional and material specifications but no stated production capacity, ISO certification, or export history. Buyers should therefore request factory audit evidence, quality management system certificates, and reference customers in comparable applications before committing to volume orders. The Shangdi International location places the firm within Beijing's established technology corridor, which supports electronics supply chain proximity but does not, by itself, confer manufacturing capability.
