We propose a wearable thermoelectric cooler and heatsink based of silicone elastomer, phase-change material, graphite powder, which can achieve cooling temperature ?5 K at 0.5 W input power for more than 5 h under ambient conditions.
A novel model of two-stage thermoelectric cooler with inhomogeneous thermal conductivity in steady-state operating condition is established. The modification the constant properties allows controlling distribution Joule heat. Considering internal irreversibilities cooler, expressions for cooling capacity, COP, and exergy efficiency are derived. By utilizing numerical methods, temperature profil...
Coiled planar capillary chromatography columns (0.9 mm I.D. × 60 cm L) were 3D printed in stainless steel (316L), and titanium (Ti-6Al-4V) alloys (external dimensions of ~5 × 30 × 58 mm), and either slurry packed with various sized reversed-phase octadecylsilica particles, or filled with an in situ prepared methacrylate based monolith. Coiled printed columns were coupled directly with 30 × 30 m...
A diode-side-pumped, high-energy, high-beam-quality, pulsed solid-state Nd3+:Y3Al5O12 (Nd:YAG) laser with a thermoelectric cooler (TEC) is investigated in this study. The pump laser was a pulsed laser diode array with maximum peak power of 15 kW. A 350 mJ laser pulse was obtained with a wavelength of 1064 nm, a pulse duration of 10 ns, a total electrical-to-optical efficiency of 7.5%, a relativ...

A mathematical model investigating influence environment variation performance a single-cascade cooler at given level cooling, load, geometry thermoelement branches different characteristiccurrent ...
Optoelectronic devices such as vertical cavity surface emitting lasers (VCSEL’s) generate large heat power densities on the order of 100’s of Wlcd . A novel device structure consisting of a two-stage monolithically integrated thin film thermionic and thermoelectric cooler is proposed to accommodate these cooling requirements. By optimizing the geometry of each stage, improved heat spreading can...
To obtain accurate measurements for brightness temperature from the IIP radiometer, it is necessary to know the temperature of the front-end components especially low noise amplifier (LNA) and microwave terminator during measurements. For this application, all of these components will be placed on a temperature-stabilized metal plate which can be achieved by using a thermoelectric cooler (TEC)....
