Thermoelectric Heat ExchangerThis study investigates the feasibility of integrating thermoelectric devices into a large-capacity liquid heat exchanger (up to 100 kW). Typically, thermal-electrical conversion is inefficient and thermoelectrics are only used in low-power applications (

HYBRID SOLAR PANEL DIAGRAMHYBRID SOLAR PANEL DIAGRAM The hybrid solar panel that Yin designed has as its outermost layer a clear protective cover, followed by a layer of thermoelectric material, a layer with plastic tubes (called the functionally graded material interlayer) to carry water that will cool the other layers while also carrying away heated water, and a bottom layer of reinforcing plastic.Image: COLUMBIA UNIVERSITY

Air-to-Air Thermoelectric Heat Exchangers
BSST's parent company, ships more than
1.2 million thermoelectric Air to Air
devices to automobile seat manufacturers
annually, making possible the cooled and
heated car seats available on many car
models. Building on this technology and
manufacturing expertise, BSST has created
Air to Air devices that provide electronic
enclosure cooling at nearly double the
efficiency of standard thermoelectric
cooling devices.

Liquid-to-air Thermoelectric Heat Exchanger
BSST's uniquely designed Liquid to Air
systems allow for significant cooling
power in a variety of form factors. In a
typical BSST configuration, ambient air
enters the device and is instantly chilled to
approximately 15 degrees Celsius. The air
is then blown over electronic systems or
critical components. The waste heat from
the process is removed by the liquid loop
(typically water, but other fluids can be
used).
