Internal seals for server racks

The combination of a server rack and an internal air seal for said rack, which comprises

• an inner frame structure for mounting of a plurality of servers and an external frame,
• said internal and external frames being separated a distance defining an air space,
• said air seal comprising an elongated strip-like support member formed of a rigid plastic material and having a length, a width and a thickness,
• said strip-like support member having first and second surfaces and side edges,
• a mounting strip formed of a plastic foam material and having a length corresponding to the length of said support member and a width less than the width of said support member and having a first surface adhesively bonded to a first portion of the first surface of said support member at one side thereof,
• a second surface of said mounting strip having an adhesive coating thereon,
• a sealing strip of resiliently flexible plastic foam material having a length corresponding to the length of said support member and a width substantially greater than a second portion of the first surface of said support member not covered by said mounting strip,
• an edge portion of said sealing strip being adhesively bonded to said second portion of the first surface of said support member,
• a cover panel mounted on said external frame,
• said mounting strip being adhesively secured to an element of said internal frame such that said flexible sealing strip extends toward and into contact with said cover panel to form an air block in an air space between said internal frame and said cover panel.

The combination of a server rack and an internal air seal for said rack, which comprises,

• a bottom frame element for said rack, said bottom frame element being of hollow construction and having outer, top and inner walls and having openings in said top and inner walls forming a passage for air to flow outwardly from within said rack through said openings, and
• said air seal comprising an elongated strip-like support member formed of a rigid plastic material and having a length, a width and a thickness,
• said strip-like support member having first and second surfaces and side edges,
• a mounting strip formed of a plastic foam material and having a length corresponding to the length of said support member and a width less than the width of said support member and having a first surface adhesively bonded to a first portion of the first surface of said support member at one side thereof,
• a second surface of said mounting strip having an adhesive coating thereon,
• a sealing strip of resiliently flexible plastic foam material having a length corresponding to the length of said support member and a width substantially greater than a second portion of said first surface of said support member not covered by said mounting strip,
• an edge portion of said sealing strip being adhesively bonded to said second portion of said first surface of said support member,
• said mounting strip being adhesively secured to an edge portion of the inner wall of said bottom frame element such that said flexible sealing strip extends toward an opposite edge of said inner wall, and
• said sealing strip having a width sufficient to extend over and cover said openings in said inner wall.
