Insulated pressure vessel holder

A bracket for insulating and mounting a housing of a pressure vessel of an air-conditioning system located within an engine compartment of an automobile, said bracket comprising:

• an elongated cylindrical sleeve having an inner surface and a bottom end having an opening therein, said pressure vessel positioned within said elongated cylindrical sleeve;
• said elongated cylindrical sleeve having an outer periphery having a shape selected from the group consisting of a sinuous shape, a crenulated shape, and a scalloped shape, said outer periphery having a first localized area in contact with said pressure vessel, said outer periphery having a second localized area spaced from said pressure vessel and defining an air pocket providing a thermal insulation to said pressure vessel;
• and
• a mounting flange outwardly projecting from said elongated cylindrical sleeve for mounting said bracket within said engine compartment.

A pressure vessel assembly comprising:

• an elongated cylindrical sleeve having an inner surface, an outer surface, a top end and a bottom end, said top and bottom ends having openings therein;
• said inner surface of said elongated cylindrical sleeve having a corrugation,
• a pressure vessel positioned within said elongated cylindrical sleeve thereby defining an area between said inner surface of said elongated cylindrical sleeve and said pressure vessel, said corrugation having a first localized area in contact with said pressure vessel, said corrugation having a second localized area spaced from said pressure vessel and defining an air pocket providing a thermal insulation to said pressure vessel;
• and
• a mounting flange outwardly projecting from said outer surface of said elongated cylindrical sleeve for mounting a bracket member.

A pressure vessel assembly adapted for use in an air-conditioning system located within an engine compartment of an automobile, said pressure vessel assembly comprising:

• an elongated cylindrical sleeve having an inner surface and a bottom end having an opening therein, said elongated cylindrical sleeve having an outer periphery having a shape selected from the group consisting of a sinuous shape, a crenulated shape, and a scalloped shape;
• a pressure vessel of said air-conditioning system positioned within said elongated cylindrical sleeve, said outer periphery having localized areas in contact with said pressure vessel mounted within said air-conditioning system, said outer periphery having localized areas spaced from said pressure vessel defining air pockets providing a thermal insulation to said pressure vessel;
• and
• a mounting flange outwardly projecting from said elongated cylindrical sleeve for mounting said pressure vessel.
