Temperature control device
View Patent ↗Temperature control devices have become common to cool the exhaust stream from a diesel particulate filter before release into the environment. To further cool the filtered exhaust stream, a temperature control device has plates that are approximately parallel and in a spaced apart relationship. A vent is located between the plates. The plates have apertures. A shield is also used.
1. A temperature control device for an exhaust apparatus for a motor vehicle, comprising:
a generally cylindrical body having an entrance tube at one end, and an exit tube at an opposite end;
plates being in an approximately parallel, spaced apart relationship and being approximately perpendicular to the generally cylindrical body, and a vent being located between the plates;
wherein the plates comprise a first plate and a second plate;
each plate having a peripheral edge, a central aperture, and peripheral apertures arranged radially between the central aperture and the peripheral edge;
a central aperture wall surrounding the central aperture and extending from the first plate and through the central aperture of the second plate;
peripheral aperture walls surrounding the peripheral apertures and extending from the first plate and through the peripheral apertures of the second plate;
a central aperture wall surrounding the central aperture of the second plate and extending from the second plate;
peripheral aperture walls surrounding the peripheral apertures and extending from the second plate;
a first shield extending radially and outwardly from the peripheral edge of the first plate;
wherein the first plate and the second plate are nested; and
wherein the first shield extends outwardly from the body toward the exit tube.
2. The temperature control device for an exhaust apparatus for a motor vehicle of claim 1 , further comprising:
a second shield extending radially and outwardly from the peripheral edge of the second plate;
a spacer separating the first plate and the second plate at the shields;
wherein the first shield contains the spacer; and
wherein the second shield extends outwardly from the body toward the exit tube and is seated on the spacer.
3. An exhaust apparatus for a motor vehicle, comprising:
exit tubing;
a filter assembly having a conduit in fluid communication with the exit tubing;
a temperature control device in fluid communication with the filter assembly and the exit tubing, the temperature control device comprising a generally cylindrical body, plates being in an approximately parallel, spaced apart relationship and being approximately perpendicular to the body, and a vent between at least two of the plates;
each of the plates having a peripheral edge, a central aperture, and peripheral apertures arranged radially between the central aperture and the peripheral edge;
wherein the plates comprise a first plate, and a second plate;
a central aperture wall surrounding the central aperture of the first plate and extending from the first plate and through the central aperture of the second plate;
peripheral aperture walls surrounding the peripheral apertures of the first plate and extending from the first plate and through the peripheral apertures of the second plate; and
a first shield extending radially and outwardly from the peripheral edge of the first plate toward the exit tubing.
4. The exhaust apparatus for a motor vehicle of claim 3 , further comprising:
a central aperture wall surrounding the central aperture of the second plate and extending from the second plate;
peripheral aperture walls surrounding the peripheral apertures of the second plate and extending from the second plate; and
wherein the first plate and the second plate are nested.
5. The exhaust apparatus for a motor vehicle of claim 3 , further comprising:
a second shield extending radially and outwardly from the peripheral edge of the second plate;
a spacer on the second shield of the second plate engaging the first shield of the first plate; and
wherein the first shield and the second shield extend radially and outwardly in the direction of the exit tubing.
6. The exhaust apparatus for a motor vehicle of claim 4 , further comprising:
a second shield extending radially and outwardly from the peripheral edge of the second plate toward the exit tubing; and
a spacer separating the plates at the first shield and the second shield.
7. An exhaust apparatus for a motor vehicle, comprising:
exit tubing;
a filter assembly having a conduit in fluid communication with the exit tubing;
a temperature control device in fluid communication with the filter assembly and the exit tubing, the temperature control device comprising a generally cylindrical body, a first plate, a second plate being in an approximately parallel, spaced apart relationship with the first plate and being approximately perpendicular to the generally cylindrical body, and a vent being located between the first plate and the second plate;
each of the plates having a peripheral edge, a central aperture, and peripheral apertures arranged radially between the central aperture and the peripheral edge;
a central aperture wall surrounding the central aperture of the first plate and extending from the first plate and through the central aperture of the second plate;
peripheral aperture walls surrounding the peripheral apertures of the first plate and extending from the first plate and through the peripheral apertures of the second plate;
a shield extending radially and outwardly from the peripheral edge of each of the first plate and the second plate toward the exit tubing; and
a spacer on the shield of the second plate separating the first plate and the second plate at the shield of the first plate.
8. A temperature control device for an exhaust apparatus for a motor vehicle comprising:
a generally cylindrical body;
a plate assembly comprising plates being in an approximately parallel, spaced apart relationship and being approximately perpendicular to the generally cylindrical body, and a vent being located between the plates;
each plate having a peripheral edge, a central aperture, and peripheral apertures arranged radially between the central aperture and the peripheral edge;
wherein the plates comprise a first plate, and a second plate;
a central aperture wall surrounding the central aperture and extending from the first plate and through the central aperture of the second plate;
peripheral aperture walls surrounding the peripheral apertures and extending from the first plate and through the peripheral apertures of the second plate;
a first shield extending radially and outwardly from the peripheral edge of the first plate in the same direction as the peripheral aperture walls of the first plate extend;
a second shield extending radially and outwardly from the peripheral edge of the second plate;
a spacer on the second shield engaging the first shield; and
wherein the second shield extends radially and outwardly in the same direction as the first shield.
