Novel Concepts Announces ThinSink, Its Thinnest Air-Cooled Heatsink
Novel Concepts announced that it has developed what they claim to be the world's thinnest forced convection (fan-cooled) heatsink dubbed ThinSink. Thinner than a credit card, this low-profile solution has a volumetric cooling efficiency 25 times greater than today's best microprocessor heatsinks, which means it cools 25 times more heat per cubic centimeter.
Developed to fit inside small electronic devices such as notebooks, monitors, and tablets; ThinSink efficiently cools integrated circuits, semiconductors, LED's and other microelectronic heat generating devices.
ThinSink's smooth fan surface requires very little electrical power. A credit-card-sized ThinSink (85x55x0.75 mm), using a smooth fan 40-mm in diameter, spinning at 6,000 RPM, consumes only 0.031 watts of electricity (up to 2 days on a AAA battery).
Even with its low power consumption, this same credit-card-sized ThinSink has thermal performance of 2.73°C/W, at a fan speed of 6,000 RPM.
ThinSink is also very quiet, due to its thin smooth fan surface, which eliminates the pulsating sound and vibration caused by traditional fan blades. At 6,000 RPM, the novelty has a sound output less than 34 dBA.
Aside from being thin and flat, ThinSink is also lightweight. An aluminum credit-card-sized ThinSink weighs only 13.8 grams, including motor, and only occupies 4.5 cubic centimeters of space.
Novel Concepts is currently pursuing partnering and licensing opportunities for its ThinSink technologies, as well as licensing opportunities for its portfolio of patents and patent applications. The single-piece price for the credit card sized ThinSink evaluation unit is $750, reduced pricing is available on larger quantities.
