Abstract
A heat exchanging device uses a shell and tube structure whereby a portion of a diesel fuel line with or without a portion of a diesel exhaust fluid line, is placed in heat-exchanging relationship with a portion of the shell. Hot fluid flowing through the shell in a vortex-like fashion heats the diesel fuel line and the diesel exhaust fluid line to improve diesel fuel mileage and diesel exhaust efficiency.
Claims10
A system, comprising:
- a diesel engine;
- a diesel exhaust fluid (DEF) reservoir;
- a diesel fuel reservoir;
- and
- a heat transfer device, the heat transfer device further comprising:
- a shell, wherein the shell further comprises:
- an inflow port;
- a void;
- and
- an outflow port such that hot fluid can pass into the shell via the inflow port, through the shell in a vortex-type flow, and out of the shell via the outflow port;
- a first diesel fuel line portion disposed between the diesel fuel reservoir and the shell such that the diesel fuel line is in a heat-exchanging relationship with the shell;
- a second diesel fuel line portion disposed within the shell, wherein the second diesel fuel line portion is constructed from a heat conductive material such that hot fluid flowing within the shelf transfers heat to the second diesel line portion;
- a third diesel fuel line portion disposed between the shell and fuel injection ports of the diesel engine;
- a first DEF line portion disposed between the DEF reservoir and the shell;
- a second DEF line portion disposed within the shell, wherein the second DEF line portion is constructed of a heat conductive material such that hot fluid flowing within the shell transfers heat to the second DEF line portion;
- and
- a third DEF line portion disposed between the shell and an exhaust subassembly of the diesel engine.

A system, comprising:
- a diesel engine;
- a diesel fuel reservoir;
- a diesel exhaust fluid (DEF) reservoir, and
- a heat transfer system disposed in a heat-exchanging relationship with the diesel fuel reservoir, wherein the heat transfer system further comprises:
- a shell, wherein the shell further comprises:
- an inflow port;
- a continuous and closed wall;
- a void created by the continuous and closed wall;
- and
- an outflow port such that hot fluid can pass into, through and out of the shell;
- a diesel fuel line extending between the diesel fuel reservoir and fuel injection ports of the diesel engine, wherein the diesel fuel line further comprises a portion that passes through the shell and heats the diesel fuel therein;
- and
- a DEF line extending between the DEF reservoir and an exhaust subassembly, wherein:
- the DEF line comprising a portion that passes through the shell and heats the DEF therein;
- and
- the exhaust subassembly further comprises:
- a diesel particulate filter (DPF);
- a selective catalytic reduction (SCR) catalyst;
- and
- an exhaust pipe portion extending between the DPF and the SCR;
- wherein the shape of the shell creates a vortex flow-like passage of fluid through the shell and around the portion of the diesel fuel line that passes through the shell and around the portion of the DEF line that passes through the shell.
