New Material Boosts Efficiency of Solar Cells and Improves Cooling

 

Researchers from Stanford University have successfully improved the efficiency of solar cells and solar panels. They have developed a transparent overlay material, a patterned silica material on top of a normal solar cell, which increases solar cell efficiency by cooling cells in full sunlight. The material works by radiating heat away from the solar cells, according to … [Read more...]

New Headlamp LED

 

During the ISAL 2015 automotive lighting symposium, Osram Opto Semiconductors introduced a 2,000 lm prototype headlamp LED called the Oslon Black Flat S. Compared with its predecessor, the headlamp LED has enhanced chips and thermal management. “Larger contact pads are partly responsible for better cooling – at 3.75×7.9mm it is slightly larger than its predecessor. When … [Read more...]

Ceramic Adhesive Bonds Thermocouples to High-Temp Heater

 

Aremco Products, Inc. recently launched the Ceramabond™ 571, a new high temperature magnesium oxide based ceramic adhesive. It is used to bond thermocouples to high temperature molybdenum-rhenium heater tubes for applications to 3200o F (1760 ºC). “Ceramabond™ 571 is ideal for assembling and insulating ceramic and metal components used in high temperature devices. It … [Read more...]

New Reversible Flow Fan Blows Air in Both Directions

 

SANYO DENKI CO., LTD. introduces the San Ace 136RF ø136 mm × 28 mm Reversible Flow Fan that blows air in both directions. “Rotational speed is controlled using an external PWM signal to deliver an appropriate rotational speed, reducing noise and saving energy,” the company said. The San Ace 136RF ø136 mm × 28 mm Reversible Flow Fan has about the same airflow and static … [Read more...]

Heat Sink Optimization through Use of Pin Fins

 

In a recent blog post, Robert Smith discusses heat sink optimization through the use of pin fins. “Local heat transfer coefficients are highest when the air first begins to form a boundary layer.  The benefit to lots of pins is that you force the boundary layers to break away often and re-create on the next pin,” Smith said. The heat sink forms a 3D mesh of pins that cross … [Read more...]
