Thermoelectrically Cooled GaAlAs Laser Illuminator
Applied Optics, 1970Required operating wavelengths in GaAs injection lasers have generally determined the operating temperature, preventing the use of optimum refrigeration systems. Recent advances in GaAIAs injection lasers have produced high efficiency lasers with selectable wavelengths from 0.8 microm to 0.9 microm. This paper discusses the refrigeration considerations

An Electronic Control Unit for Thermoelectric Cooling
2019 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (EIConRus), 2019Due to their efficient operation in small volumes, Thermoelectric Coolers (TECs) have a wide usage in cooling applications, and are preferable wherever usage of compressor-based cooling systems is hard. In this study, a control unit for thermoelectric cooling modules has been designed and implemented based on a microcontroller.

Efficient thermoelectric cooling for mobile devices
2017 IEEE/ACM International Symposium on Low Power Electronics and Design (ISLPED), 2017Mobile apps suffer large performance degradation when the underlying processors are throttled to cool down the devices. Fans or heat sinks are not a viable option for mobile devices, thus calling for a new portable cooling solution. Thermoelectric coolers are scalable and controllable cooling devices that can be embedded into mobile devices on the chip

A Thermoelectrically Cooled Microtome Table and Knife
Stain Technology, 1964Thermoelectric cooling units (Frigistor thermoelements) have been used to replace CO2 gas and solid CO2 for microtome stage and knife cooling. These units consist of assemblies of series-connected thermoelements, functioning by the Peltier effect. Cooling is controlled by the direct current supply to the units.

Cooling power of transverse thermoelectrics for cryogenic cooling
SPIE Proceedings, 2016Transverse Peltier coolers have been experimentally and theoretically studied since 1960s due to their capability of achieving cooling in a single-leg geometry. Recently proposed p x n -type transverse thermoelectrics reveal the possibility of intrinsic or undoped transverse coolers that can, in principle, function at cryogenic temperatures, which has

Thermoelectric Cooling Through Thermoelectric Materials
2010Thermoelectric (TE) cooling has been used for thermal management of high-power-dissipating electrical components, with silent, compact, reliable, and durable characteristics and being modulated to maintain a fixed temperature. However, TE coolers currently in use have a coefficient of performance (COP) of only about 0.5.

Enhanced thermoelectric cooling performance with graded thermoelectric materials
Japanese Journal of Applied Physics, 2018Abstract An analytic model is presented to estimate the performance of the thermoelectric refrigeration constructed by the functional graded thermoelectric materials with the spatial- and temperature-dependent transport coefficients, such as the Seebeck coefficient, the thermal conductivity and the electrical conductivity along the ...

Thrifty thermoelectric cooling
Science, 2019Thermoelectrics Currently available thermoelectric devices for cooling rely on expensive bismuth telluride. Mao et al. systematically developed a far less expensive n-type magnesium-bismuth–based material with good thermoelectric properties. They built a device that could generate a temperature difference of up to 90 kelvin when coupled with a ...

Lowest temperature at thermoelectric cooling
2007 4th International Conference on Electrical and Electronics Engineering, 2007One-dimensional model of thermoelectric module is suggested, and the lowest temperature of thermoelectric cooling is obtained. It is supposed that cooling occurs due to the classic Peltier's effect, and the thermoelectric module operates in the mode when no external thermal load is applied.
