Thermoelectric coolers with vortex apparatus

XVI ICT '97. Proceedings ICT'97. 16th International Conference on Thermoelectrics (Cat. No.97TH8291), 2002
Results of thermodynamic characteristics of the combined cooling system consisting of a thermoelectric cooler and a jet cooler in the form of a vortex tube have been given. General relations for their description based on the exergetic method of thermodynamic system calculations have been obtained.

Highly integrated thermoelectric coolers

2016 15th IEEE Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems (ITherm), 2016
Thermoelectric coolers (TECs) are an effective technology for managing heat loads in high-performance electronic components. While most TECs are fabricated using bulk thermoelectric (TE) materials, thin-film thermoelectrics have been shown to be a viable alternative. Thin-film TE coolers (TFTECs) have several advantages in comparison with bulk devices,

On the preparation of materials for thermoelectric coolers

Journal of Scientific Instruments, 1965
The quartz container used by Satterthwaite and Ure for making Bi2Te3 and its solid solutions by the Bridgman method of crystal growing is modified by the incorporation of four tubes, thus giving four identical ingots. A single furnace is used, without bottom cooling provision.

Multistage thermoelectric microcoolers

Journal of Applied Physics, 2003
Multistage thermoelectric coolers have been used for a long time because they offer a larger temperature difference than single-stage thermoelectric coolers. Microelectromechanical systems technology leads to the possibility to fabricate multistage thermoelectric microcoolers in batches without much increase in complexity compared to single-stage ...

Thermoelectric cooler concepts and the limit for maximum cooling

Journal of Physics: Condensed Matter, 2014
The conventional analysis of a Peltier cooler approximates the material properties as independent of temperature using a constant properties model (CPM). Alternative concepts have been published by Bian and Shakouri (2006 Appl. Phys. Lett. 89 212101), Bian (et al 2007 Phys. Rev. B 75 245208) and Snyder et al (2012 Phys. Rev. B 86 045202).

Thermodynamic Analysis of Thermoelectric Coolers

International Journal of Mechanical Engineering Education, 1998
A thermodynamic analysis of a thermoelectric cooler is proposed. The coefficient of performance of the cooler is expressed in terms of two dimensionless parameters which are to be optimized. The thermoelectric cooler is considered as an irreversible Carnot-like reversed heat engine.

Design and development of controller for Thermoelectric cooler system

2015 IEEE International Conference on Control System, Computing and Engineering (ICCSCE), 2015
The Thermoelectric cooler (TEC) is widely known device which have low coefficient of performance (COP) as compare to the conventional compressed refrigerator. However, it is suitable for portable refrigeration that requires light weight, small and fast control.

Equivalent circuits of thermoelectric coolers.

2009
Equivalent circuits are useful for simplified representation and deeper understanding of electrical devices. In this work a thermoelectric system is represented by equivalent circuits. The first part of work is introductory. It contains the definitions and derivations of the various thermoelectric effects. A detailed description of the construction and

A COOLER APLICATION WITH THERMOELECTRICS METARIAL

2015
A Thermoelectric material is a semiconductor product whichgenerates current, when a temperature difference between occurs two surfaces orwhile one face is getting hotter, the other face is getting cooler when acurrent flows through it. It is used in many fields because of increasing costdepending on the improvement on the technology.

A thermoelectric cuvette cooler for optical studies in cryobiochemistry

Cryobiology, 1979
Abstract The inflexibility, inconvenience, and large cost of a liquid nitrogen-cooled gaseous temperature regulator can be circumvented using Peltier-junction technology. The advantages offered in such a system are apparent, and could easily open the door to further capitalization of the elegant cryoenzymology techniques pioneered by Douzou.
