Problems solved by technology

[0003] The problem faced by the device disclosed in WO9830786 is that the sealing of the working medium, especially the high pressure (which can reach 200 bar or more), makes this method less reliable

Embodiment Construction

[0067] Figure 1a The illustrated chamber unit 100 comprises three copper tubes 101 of circular cross-section with two common ends 102 . The chamber unit 100 is provided with a cylinder 103 having a piston 104 . Figure 1b shown Figure 1a A partially cut-away bottom view of the chamber unit 100 of FIG.

[0068] The copper tube 101 is enclosed within a second tube 106, here in the form of a plastic hose, having an inlet 107 for a heat exchange medium and an outlet 108 for said heat exchange medium. The heat exchange medium is usually water, but can be of various compositions.

[0069] The copper tube 101 , the cylinder 103 and the piston 104 define a closed chamber 105 containing a working medium with super expansion. An example of a suitable working medium is paraffin VP858 (Sasol, Hamburg, Germany). In order to prevent the working medium from escaping from the closed chamber 105, a sealing ring 176 is provided, sealing the piston 104 with Teflon. figure 2 The expansion ...

Abstract

The present invention relates to a method of converting thermal energy into mechanical energy using a non-gaseous working medium present in an apparatus comprising a plurality of heat exchangers and an outgoing shaft. In accordance with the invention, the apparatus used comprises a multitude of chamber units,; a chamber unit comprising an inlet for introducing heat exchange medium and an outlet for discharging heat exchange medium as well as a closed chamber having a heat exchanger wall for exchanging heat between working medium inside the closed chamber and the heat exchange medium introduced into the chamber unit via said inlet for introducing heat exchange medium and heat exchange medium is passed around so as to do work when it is giving off heat to a chamber unit containing relatively cool working medium and recuperate heat when it is passed through a chamber unit containing relatively warm working medium. The invention also relates to an apparatus for performing the method.

Description

technical field [0001] The present invention relates to a method of converting thermal energy into mechanical energy utilizing a non-gaseous working medium in a device comprising heat exchangers and an output shaft. Background technique [0002] For economical and environmental reasons, there is a huge drive to use energy as efficiently as possible. Large quantities of low-quality heat can be obtained, such as waste heat from industrial processes or other sources, or generated by solar energy. But unfortunately, what is most needed is a high-quality energy source, such as mechanical energy that can be converted into electricity, which is more popular. WO9830786 (PCT / NL98 / 00012) discloses a method and device for converting thermal energy into mechanical energy. It utilizes paraffin as the working medium. Paraffin is a substance that exhibits hyperswelling properties, i.e. expansion >0.01% per °C, over a (limited) temperature range. Typical values ​​for paraffin coeffic...
