A cylindrical, annular axial flow heat exchanger for use as a gas cooler in a thermal regenerative machine such as a Stirling engine is provided. The heat exchanger includes an outer shell of sufficient strength and thickness to withstand the pressure exerted by the working fluid and a tubular member positioned adjacent to and in contact with the outer shell, the tubular member having spaced apart sidewalls defining a flow passage therebetween. At least one of the sidewalls of the tubular member is embossed with ribs, the ribs being in contact with the inner surface of the outer shell thereby defining axially extending flow passages between the outer shell and tubular member along the circumference thereof for the flow of a second, gaseous fluid through the heat exchanger. The first fluid flows circumferentially through tubular member, while the second fluid flows axially between the outer shell and the tubular member.

HEAT EXCHANGING CYLINDER HEAD

Номер: US20130067906A1
Автор: Macarez Bernard Gilbert
Принадлежит:

This engine () (of the piston engine or rotary Wankel-type engine type) includes a heat-exchanging cylinder head () which transfers to the fluid internal to the engine the heat energy collected from an external hot source (liquid, gaseous or by radiation). In a closed or open cycle it uses a gaseous fluid (air) or a refrigerant such as an engine fluid in particular when the temperature of the hot source is low. The volumetric compression ratio of the engine is optimized according to the temperature level of the hot source in order on the one hand to allow the internal heat exchanging cylinder head () and () to be positioned in the dead volume freed inside the chamber (piston top dead center) of the engine () and on the other hand to extract significant mechanical work. It is a matter of increasing technological feasibility at the expense of an acceptable loss in efficiency given that the contribution from the hot source is free of charge. It avoids the adding of a bulky external heat exchanger and the associated problems of the thermal and mechanical stresses thereof and also makes it possible to reduce the flow rate of the engine fluid (for example air) transferred to a strict minimum. By comparison with competing systems, this invention does not require the engine fluid to be transferred to the hot source and vice-versa and there are therefore no additional valves and the engine air flow rate is minimum. It is a relatively inexpensive invention particularly suited to the field of the recovery of free or wasted heat (exchange with a hot external fluid—exhaust gas or radiation) where other technological solutions with a higher overall efficiency are either technologically unfeasible or require too great an investment thereby jeopardizing their economic model 1119356432121199112172481213714.

The disclosure describes a method to operate a conventional 4 cylinder engine as an expander for any pressurized fluid (e.g., liquid, vapor, or gas). A poppet valve system is disclosed enabling upward lift of the inlet valve, with assist from cylinder compression pressure, together with downward lift from an exhaust valve, resulting in especially efficient expansion of fluid or gas in a thermodynamic power cycle. Further, it is described that a desmodromic valve operation system may be employed and provides essential guidance and opening closing actions for proper operation of the expander system.

A working volume of gas is drawn into the induction-displacer, then displaced into the combustion-expander ( 2 ) at substantially constant volume passing through the regenerator ( 5 ). The gas in the combustor-expander ( 2 ) is further heated by combustion of a fuel then expanded to extract work. The gas is then displaced through the regenerator ( 5 ) into the atmospheric-cooler ( 3 ) at substantially constant volume, or exhaust from the regenerator at constant pressure. The gas is contracted in the atmospheric-cooler doing atmospheric work. Once the gas has equilibrated with the pressure of the atmosphere it is exhaust from the atmospheric-cooler ( 3 ).

System and modality to generate power from liquid jet in heat engine and more

Human used to get power from gas expansion in heat engine. Extraction of mechanic work from gaseous expansion is always low efficient, because circa 70% energy is hidden in the exhausted vapor in the form of latent heat and rejected or dumped out of cycle because the slow condensation may choke mass conservative looping. As liquid is hard to be compressed, power transmission can be reasonably assumed lossless, so harvesting mechanic power from liquid flow is high efficient. But historically it is rarely considered for how to form a powerful liquid flow in a typical gas-liquid dual-phase co-existed thermodynamic system, such as the most used Rankine-cycle heat engine. A new method or say Wei heat engine is invented that is based on a new defined Wei second class thermodynamic cycle. Such a new method converts thermal energy into high speed liquid flow during non-equilibrium condensation, though not too much efficient, as well as it jailbreaks the efficient limit of ideal Carnot cycle in an alternative way because the rejected heat is automatically reused to heat base liquid so as to reduce the consumption of heat source. 19910aa.
