Abstract
A cooling device including an air source, preferably a fan, that provides air flow and a shroud for directing air flow from the air source at an object, particularly a coil of material, preferably a metal or metal alloy having a temperature greater than the ambient room temperature. The cooling device provides cooling efficiency by directing the air from the air source at an increased velocity to a desirable area or areas on an end surface of the object, thereby increasing heat transfer from the object. The cooling device shroud includes an air directing surface that influences the direction of air flow across the object in a desired pattern. Methods for preparing cooling devices and for cooling objects are also described.
Claims40
A cooling device for use in cooling an article, comprising:
- an air source that provides air flow;
- and
- a shroud that receives air flow from the air source and is adapted to direct the air onto a surface of the article, wherein the shroud includes a receiver that is connected to an air exhaust outlet of the air source, wherein the shroud includes an air directing surface having one or more apertures through which air flows out of the shroud, and wherein the one or more apertures have a total cross-sectional area that is less than a cross-sectional area of the air exhaust outlet.
A cooling device for use in cooling a coil of material, comprising:
- an air source that provides air flow through an air exhaust outlet;
- and
- a shroud connected to the air source that receives air from the air source exhaust outlet and is adapted to expel the air through one or more apertures of an air directing surface of the shroud, wherein the shroud includes an adaptor connected to the air directing surface of the shroud and adapted to substantially seal a core of the coil to prevent air flow through the core.
A method for cooling a coil, comprising the steps of:
- providing a coil of material at a temperature above an ambient temperature;
- providing a cooling device comprising an air source that provides air flow and a shroud that receives air flow from the air source and is adapted to direct the air onto a surface of the coil, wherein the shroud includes a receiver that is connected to an air exhaust outlet of the air source, wherein the shroud includes an air directing surface having one or more apertures through which air flows out of the shroud;
- positioning the air directing surface of the cooling device adjacent an end of the coil;
- and
- directing air from the cooling device onto the coil end to cool the coil, wherein a velocity of the air exiting the one or more apertures is greater than a velocity of the air exiting the air exhaust outlet.
A cooling device for use in cooling an article, comprising:
- an air source that provides air flow;
- and
- a shroud that receives air flow from the air source and is adapted to direct the air onto a surface of the article, wherein the shroud includes a receiver that is connected to an air exhaust outlet of the air source, wherein the shroud includes an air directing surface having one or more apertures through which air flows out of the shroud, wherein the air directing surface is substantially planar radially outward of an adaptor connected to the air directing surface and wherein the air directing surface is adapted to be positioned substantially parallel to a plane formed by an end of the article.
