Product description

High-Efficiency Die-cast Aluminum LED Heat Sink – Ruggedized 200W-Ready High Bay Light Housing with Radial Cooling Fins & IP66 Waterproof Integration

? ? ?The Die-cast Aluminum LED Heat Sink by VKE is a heavy-duty thermal management solution engineered for high-wattage industrial lighting. Utilizing a High Pressure Die Casting Tooling process with premium ADC12 or AL6063 alloys, this housing features a sophisticated radial fin architecture designed to maximize natural air convection.Optimized for 100W to 200W COB LED light sources, it combines structural housing and advanced cooling into a single, high-durability component. VKE leverages Electronic Enclosure Die Casting expertise to ensure that every fin and internal cavity is cast with zero porosity, maintaining peak thermal conductivity for the most demanding factory or outdoor environments.

Engineering Highlights & Thermal Logic

Optimized Convection Geometry: The vertical fin arrangement is scientifically spaced to prevent dust accumulation while creating a "chimney effect," pulling cool air from the bottom to dissipate heat rapidly.
Integrated Component Housing: Unlike standard heat sinks, this unit features dedicated side ports designed for IP68 Cable Gland integration and internal cavities for driver wiring. This simplifies the assembly of waterproof luminaires.
Precision Interface Finishing: The central mounting area for the COB source is refined via Custom CNC Machining to ensure absolute flatness, which is critical for maximizing heat transfer between the LED and the aluminum body.
High-Adhesion Surface Protection: The dark gray finish is achieved through a specialized electrophoretic process that increases infrared radiation efficiency while protecting the aluminum from oxidation.
Structural Rigidity: Reinforced corner mounting bosses provide high pull-out strength. As a specialized High Pressure Die Casting Tooling maker, VKE ensures these bosses can support the weight of heavy-duty U-brackets or suspension chains in overhead installations.
