Abstract
There is disclosed a baffle having a medium that allows a fluid such as air to flow therethrough.
Claims20
A baffle for insertion into a cavity of a structure of an article of manufacture, comprising:
- a generally planar flow through medium having an outer periphery and a plurality of openings, which allow air to flow through the medium;
- and
- an expandable material that is substantially coextensive with the outer periphery of the medium, the expandable material being activatable such that the expandable material can expand and adhere to walls of the structure of the article of manufacture.
A baffle for insertion into a cavity of a structure of an automotive vehicle, comprising:
- A flow through medium having a plurality of openings, which allows air to flow through the medium wherein:
- i) the flow through medium is formed of a substantially planar sheet having an outer periphery and a first surface opposite a second surface separated by a thickness;
- ii) the first surface has a surface area of at least 0.5 decimeters and has an average opening frequency of at least 2 openings per square centimeter of said surface area;
- and
- an expandable material connected to the medium, wherein:
- i) the expandable material expands, foams, wets and adheres to walls of the cavity of the structure of the automotive vehicle upon exposure to elevated temperatures;
- and
- ii) the expandable material is adjacent to and substantially coextensive with the outer periphery of the medium.

A baffle for insertion into a cavity of an automotive vehicle, comprising:
- a medium having a plurality of openings, which allow air to flow through the medium wherein:
- i) the medium is formed of a substantially planar metal sheet having an outer periphery and a first surface opposite a second surface separated by a thickness;
- ii) the first surface has a surface area of at least 0.5 decimeters and has a density of openings of at least 2 openings per square centimeter of said surface area;
- and
- iii) each of the openings includes a flow-through area of less than about 3 square millimeters and greater than about 0.2 square millimeters;
- an expandable material connected to the medium, wherein:
- i) the expandable material expands, foams, wets and adheres to walls of the cavity of the structure of the automotive vehicle upon exposure to elevated temperatures;
- and
- ii) the expandable material is adjacent to and substantially coextensive with the outer periphery of the medium;
- and
- a housing including a first wall with a first through-hole and a second wall with a second through-hole, wherein:
- i) the flow through medium is between the first and second walls of the housing;
- and
- ii) the first and second through-holes provide fluid communication with the flow through medium.
