New Peltier semiconductor heat transfer systems are presented herein. In particular, Peltier heat transfer systems of Peltier semiconductor elements of highly unique shapes are arranged to bias the cooling side with respect to its size and consequently performance. In effect, a Peltier heat transfer system is created whereby the Peltier called side is greatly reduced in size and the Peltier hot side is greatly expanded in size. Such 'high aspect ratio' Peltier systems promote 'focused' cooling effect, which is particularly useful in conjunction with high-performance electronic devices having a small footprint. The entire cooling fact of the Peltier device is brought to the small space approximated by a point. Thus a &#x2018;point&#x2019; heat source such as a semiconductor laser are high-performance light emitting diode is more effectively cooled by these systems.

Peltier cooling systems with high aspect ratio

An electro acoustic device and related method for increasing the production capacity of wells that contains oil, gas and/or water is disclosed. The electro acoustic device is submerged in the well producing zone, and includes an electric generator, one or more electro acoustic transducers, and one or more wave guide systems (sonotrodes) that include radiators which transmit vibrations into the medium under treatment. The electro acoustic device produces vibrations that stimulate the occurrence of mass transfer processes within the well. According to one or more embodiments, shear vibrations are produced in the well bore region due to the phase displacement of mechanical vibrations produced along the axis of the well, achieving alternate tension and pressure due to the superposition of longitudinal and shear waves.

Acoustic well recovery method and device

An electro acoustic device and related method increase production capacity of wells that contain oil, gas and/or water. The electro acoustic device produces vibrations stimulating occurrences of mass transfer processes within the well. The resultant acoustic flow generated in porous media, produced by superposition of longitudinal and shear waves, is developed over a characteristic frequency threshold value specific to water, normal oil and heavy oil, with an acoustic energy density capable of establishing higher fluidity zones in the porous media, promoting mobility and recovery of desired fluid and formation damage reduction in a wellbore.

In the oil-producing industry, an apparatus can be used to increase the yield of oil wells developed by conventional methods during production of high viscosity oils. Use of the apparatus results in an increase in the permeability of a reservoir and a reduction in the viscosity of oil, added to an increase in environmental safety by avoiding use of chemical reagents and steam generators. The apparatus applies a high power ultrasonic field in the well bottom zone that reduces viscosity of oil, also heating the well bottom zone. The apparatus comprises a surface ultrasonic generator and at least one ultrasonic magnetostrictive radiator placed at the end of oil well tubing, using high frequency currents that warm the tubing and maintain the viscosity of oil during transport to the surface.
