Benefits of technology

The present invention aims to provide a unit that can efficiently convert thermal energy while keeping its size contained and its hydraulic-electrical circuitry organized. The technical effects of the invention are high energy performance and a compact size.

Problems solved by technology

The solution in question is characterized by the use mainly of a plate exchanger within which the exhaust gases of the motor vehicle flow, a process that in certain circumstances may limit the performance of the system as well as the flexibility thereof.
The first solution is evidently undesirable in so far as the bypass conduit for the exhaust gases is very close to the second heat-exchange unit and may consequently generate heating of the second thermovector fluid even when this is not desired, whereas the second solution is characterized by a substantial doubling of the transverse encumbrance, as well as by a considerable complication in the construction of the ensemble of conduits and ducts for circulation of the second thermovector fluid.

Embodiment Construction

[0032]The reference number 1 in FIG. 1 designates as a whole a unit for conversion of thermal energy according to a preferred embodiment of the invention. The conversion unit 1 includes a first heat-exchange unit 2 defining a first flow path F2 for a first thermovector fluid. The first flow path F2 develops between a first inlet port 2IN and a first outlet port 2OUT. The first inlet port 2IN and the first outlet port 2OUT are located on one and the same side of the first heat-exchange unit 2 and have a baffle 2W set between them in such a way that a substantially U-shaped geometry is bestowed on the first flow path F2, as is represented schematically in FIG. 1.

[0033]The first inlet port 2IN and the first outlet port 2OUT are set alongside one another straddling the baffle 2W, in correspondence of which a valve V is present for controlling the flow of the first thermovector fluid. The valve V is preferentially provided as a throttle valve hinged at one end, which is rotatable about a...

Abstract

Described herein is a unit for conversion of thermal energy designed in particular for installation along an exhaust-gas line of a motor vehicle and configured for exchange and conversion of the thermal energy of the exhaust gases.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a unit for conversion of thermal energy configured for exploitation of energy of a thermovector fluid coming from an external source, for example the exhaust gases of a vehicle equipped with internal-combustion engine.DESCRIPTION OF THE PRIOR ART AND GENERAL TECHNICAL PROBLEM[0002]Units for conversion of thermal energy designed for use as heat exchangers for recovery of energy from exhaust gases of a motor vehicle are known from a number of prior documents. The present Applicant has proposed a solution of this type in the European patent application published as EP 2 561 207 A1.[0003]The solution in question is characterized by the use mainly of a plate exchanger within which the exhaust gases of the motor vehicle flow, a process that in certain circumstances may limit the performance of the system as well as the flexibility thereof.[0004]A further solution for heat exchangers used on the exhaust-gas line (EGL) of a motor ...
