Integrated system and method of battery cooling for a hybrid or fuel cell vehicle
First Claim
1. An acoustically improved cooling system for an energy storage system including a battery and a carpeted vehicle compartment comprising:
- a carpet portion sufficiently spaced from a floor panel of a vehicle to at least partially define a cavity;
an air inlet opening integrally formed in said carpet portion, wherein air from said compartment may be drawn into said cavity through said air inlet opening;
a frame in contact with said carpet portion and mounted above said floor panel of said compartment for supporting said carpet portion;
wherein the frame includes a planar surface, first side wall, second side wall and third side wall;
wherein said air from said compartment enters into said cavity through respective openings in each of said planar surface, said first side wall, said second side wall and said third side wall;
a fan for circulating air from said cavity into heat exchange relationship with said battery for cooling said battery, wherein the fan and the battery are located below the floor panel of the vehicle; and
a vent opening integrally formed in the floor panel of the vehicle, the vent opening connecting said cavity and said fan in air flow communicationsaid frame further comprising a front wall and a curved portion extending forward from said front wall, the curved portion being substantially above the vent opening.

Abstract
An acoustically improved cooling system is provided for an energy storage system including a battery with air from a carpeted vehicle compartment, the cooling system including: a carpet portion sufficiently spaced from a floor panel of a vehicle to define a cavity forming an air passage through which air may flow and including an air inlet opening integrally formed therein through which the air from the compartment may be drawn; a fan for circulating air from the cavity into heat exchange relationship with the battery for cooling the battery; and a vent opening connecting the cavity and the fan in air flow communication. The frame is curved above the vent opening, to force noise reflection off the curved portion of the frame. A sound absorption layer is installed underneath the curved portion of the frame for noise attenuation.

8. A cooling and noise attenuation system for a battery mounted with respect to a carpeted vehicle compartment comprising:
-
a carpet portion raised a finite distance above a floor panel of said vehicle compartment to at least partially define a cavity; a frame in contact with said carpet portion and mounted above said floor panel of said vehicle compartment for supporting said carpet portion said finite distance above said floor panel of said vehicle; an air inlet opening integrally formed in said carpet portion, through which air from said vehicle compartment of said vehicle may be drawn into said cavity; a fan for blowing said air through said cavity to said battery for cooling, wherein the fan and the battery are located below the floor panel of the vehicle; a vent opening integrally formed in the floor panel of the vehicle, the vent opening interconnecting said cavity and said fan; wherein said frame comprises a planar surface, three side walls and a front wall;
wherein a curved portion of the frame extends forward from the front wall and is substantially above said vent opening to force noise reflection off said curved portion;wherein said curved portion at least partially defines said cavity; and a sound absorption layer in contact with said curved portion to absorb said noise reflected off said curved portion. - View Dependent Claims (9)
