摘要:
Thermal energy is extracted from geological formations using a heat harvester. In some embodiments, the heat harvester is a once-through, closed loop, underground heat harvester created by directionally drilling through hot rock. The extracted thermal energy can be converted or transformed to other forms of energy.

This invention relates to devices for the conversion of the kinetic energy of heat carrier flows to thermal energy, and can be used as an alternative solution to heaters. The converter comprises a set of rings in a quantity of at least 100 made from a corrosion resistant material and secured inside a pipe by means of fixtures, wherein the diameter of the channel formed by said rings varies in a wave-like manner.

A fluid heating apparatus (10) using cavitation includes a housing (9), an external rotor (5) with cavitation bores (37) in an outer surface thereof, and a motor (1) for rotating the external rotor (5). An inner surface (15) of the housing (9) is spaced from the outer surface of the external rotor (5) to create a fluid heating zone. The inner surface of the housing is configured with a spiral shape and wave form to enhance the heating of the fluid.

In a waste collection system where deposited waste is transported by partial vacuum in transport pipes (2) leading from spaced collection points to a central collection station (4) containing a system vacuum source (5) including at least one vacuum-producing machine (6), thermal energy is extracted from a vacuum-producing machine exhaust air stream (EAS), is transferred to a fluid medium and is used for heating or cooling purposes in a specific residential area where the deposited and transported waste is generated.
摘要:
A substantially non-elastic incompressible composition, which substantially does not quickly self-level under standard operating conditions, includes: a suspending agent which reacts substantially as a solid when subjected to forces below a critical force, and which becomes substantially flowable when subjected to forces above said critical force; ceramic microparticulates dispersed within the suspending agent; flexible-walled microparticulates dispersed within the suspending agent; and celled macroparticulates dispersed within the suspending agent. The composition provides an incident energy absorbing property. The incident energy may include sound energy, and the microparticulates and macroparticulates may convert some of the sound energy into heat, or may diffract the sound energy.

Disclosed herein is an exemplary supplemental heating system including a hydrodynamic heater and a heat exchanger. The hydrodynamic heater includes a hydrodynamic chamber disposed within an interior cavity of the hydrodynamic heater. The hydrodynamic chamber is operable for selectively heating a fluid present within the hydrodynamic chamber when the heating apparatus is connected to a fluid supply source. The hydrodynamic heater includes an inlet port fluidly connected to a discharge port of the heat exchanger, and a discharge port fluidly connected to an inlet port of the heat exchanger. The heat exchanger includes a heat exchanger core disposed within an interior cavity of the heat exchanger. A wall at least partially defines the interior cavity of the hydrodynamic heater and the interior cavity of the heat exchanger.

This invention relates to a device (5) for the secondary production of heat intended to be fitted to a closed-circuit thermodynamic system combining primary means (1) for the production of heat by compression of a fluid, with a heat exchanger (2), these being connected together by a fluid flow channel (3). This device (5) consists primarily of a plurality of elementary channels (8, 9) interposed between an inlet chamber (11) and an outlet chamber (13), each of these chambers (11, 13) having an inlet duct (10) and an outlet duct (12), respectively, said ducts being coaxial and their respective main cross sections being identical and corresponding to the sum of the sections of the elementary channels (8, 9).
摘要:
Provided is an ultrasonic hair setting device (1) comprising a body (10), an ultrasonic vibration block (2) mounted in the body, a clamping lever (6) turnably mounted on the body (10), and a holding plate (7) carried on the clamping lever (6) and having a pressure face (8). The ultrasonic vibration block (2) includes an ultrasonic vibrator (3), and an ultrasonic horn (4) having a vibration face (5), and is provided with a comb-shaped protecting member (9) formed to enclose the vibration face (5). Even if a user has a finger clamped between the clamping lever (6) and the body (10), the finger contacts with the protecting member (9) so that it hardly touches the vibration face (5) directly. As a result, the ultrasonic vibration cannot be transmitted to the finger thereby to prevent the same from a burn.
