Peltier technology opens new opportunities for special applications. In the current project, this technology was applied to design and fabricate a portable thermoelectric beverage cooler and thermoelectric cup. The simulation and results of the experiment showed that the common beverage cooler is not a suitable design for ignoring the effect of natural convection in cooling. In our thermoel...

We present a novel thermoreflectance technique to visualise quasi-static Peltier and Joule thermal distributions simultaneously, enabling side-by-side comparison in situ. The main principle is an extension of so called ’-bucket’ imaging techniques well documented in the literature. The method is particularly advantageous in improving both the reliability and turnaround time for the characteris...

Peltier devices, also known as thermoelectric devices (TEDs), are solid state junctions of two dissimilar materials in which heat transfer and electrical conduction are coupled. A current running through a TED causes heat to flow; likewise, the presence of an external temperature gradient will induce an electrical potential across the TED. The former effect is known as the Peltier effect; the l...

Thermoelectric effects allow the generation of electrical power from waste heat and the electrical control of cooling and heating. Remarkably, these effects are also highly sensitive to the asymmetry in the density of states around the Fermi energy and can therefore be exploited as probes of distortions in the electronic structure at the nanoscale. Here we consider two-dimensional graphene as a...

We present a simple modification for thermoelectrically cooled photomultiplier tube (PMT) assemblies that eliminates the magnetic interference between the peltier element and the PMT. An active compensation is accomplished by forming current loops of the wires of the peltier element and placing them in such a way that they eliminate the interfering magnetic field. It is demonstrated that the im...
