LED Heat Sinks DUAL LED Heat Sink- Active & Passive w/ Fan Attachment Wakefield- Vette s DUAL LED Series heat sinks are extremely versatile for a customer s application whether they require either an active or passive solutions. Each DUAL LED Heat Sink has a built-in option which lets the customer add a standard, silent fan in less than a minute, with just four screws, and get more than a five-times improvement in thermal resistance and wattage rating up to 700 watts. Features: Single-Piece Forged-Aluminum Construction For Low Thermal Resistance & Compact Form-Factor Eleven Models Ranging from 58 mm to 225 mm Diameter with Thermal Resistance As Low As .35 Deg C/W For Passive Cooling up to 150 Watts Compatible with all SMD LED arrays, COBs, and Driverless AC-LEDs From All Major LED manufacturers Maximum LED Diameter Height Passive Thermal Fan Size (mm, edge Fan DC Fan Current Active Thermal Active Watts WKV Part Number Watts ( 25C Fan RPM (mm) (mm) Resistance (C/W) x thickness) Voltage (mA) Res (C/W) ( 25C Ambient) Ambient) DUALLED-5830 58 30 5.90 6 40 x 20 12 20 4000 1.18 48 DUALLED-5850 58 50 3.90 13 40 x 20 12 20 4000 0.78 70 DUALLED-5880 58 80 3.35 15 40 x 20 12 20 4000 0.67 85 DUALLED-6830 68 30 4.00 12 40 x 20 12 20 2000 0.80 72 DUALLED-6850 68 50 3.20 16 40 x 20 12 20 2000 0.64 90 DUALLED-6880 68 80 2.70 19 40 x 20 12 20 4000 0.54 105 DUALLED-13030 130 30 2.80 18 80 x 25 12 70 2100 0.56 102 DUALLED-13050 130 50 1.05 33 80 x 25 12 70 2100 0.21 260 DUALLED-13080 130 80 0.83 60 80 x 25 12 70 2100 0.17 34 DUALLED-19037 190 37 0.70 75 120 x 25 12 80 1300 0.14 400 DUALLED-22560 225 60 0.35 150 120 x 25 12 60 1300 0.08 750 See following pages for High Performance Active Solutions www.wakefield-vette.comLED Heat Sinks DUAL LED Heat Sink- Active & Passive w/ Fan Attachment All DUAL LED heatsinks have pre-drilled and tapped holes in the baseplate so that a fan can be attached to the pin side (blowing air into the pins) with just four 6-62 screws of proper length (or longer screws with appropriate washers or spacers. Wakefield-Vette lists the DUAL LED heat sinks and suggested fan type to achieve silent operation and life expectancy approaching 100,000 hours. Please note that all fans should be DC dual-ball-bearing brushless type. For Use in Active Cooling Mode... Insert the four long 6-32 screws through the four fan-mounting holes, through spaces between the blade- like pins of the heat sink and into the four tapped holes, into back side of the base plate. Connect plus and minus fan wires to power supply by direct solder connection or by means of an appropriate interconnect PC board. 12V/2 watt power supply for fan (Fan requires less than one watt of power) Meanwell Model IRM-02 or equivalent 1.33 X .87 X .4 Recommended hardware for fan mounting in active-cooling mode: Baseplate Heat Total Recommended Recommended Screw DUALLED- McMaster Item thickness sink Height screw length spacer thickness protrusion XXXXX part height with U.S. 6-32 under screw head through Part number fan thread McMaster part no. baseplate Number for screw U.S dimension (inches) 6-32 U.S. mm mm mm inches thread 5830 none 1 5 30 50 2.0-- 90272A288 .030 5850 inch 2 5 50 70 3.0 90272A161 .010 94639A301 5880 none 3 5 80 100 4.0 99117A110 .060 6830 4 5 30 50 2.0 90272A159 none .030 6850 inch 5 5 50 70 3.0 90272A163 none 94639A301 6880 6 5 80 100 4.0 99117A110 none .070 13030 7 10 30 55 2.0 90272A288 none none 13050 8 10 50 75 3.0 90272A163 none .050 13080 9 10 80 105 4.0 99117A110 none none 19037 10 10 37 62 2.5 90272A161 none .060 22560 5/8 inch 11 10 60 85 4.0 99117A110 .015 94639A304 www.wakefield-vette.com
