Abstract:
A planar manifold with a plurality of pneumatic channels therein, comprising:a high temperature zone comprising manifold ports for the attachment of fluid-handling devices, the high temperature zone having cavities through the planar manifold opening onto the major surfaces thereof at the perimeter of the high temperature zone; a low temperature zone comprising manifold ports for the attachment of unheated fluid-handling devices; and an insulating zone thermally separating the high temperature zone from the low temperature zone, the insulating zone including cavities through the planar manifold opening onto the major surfaces thereof, such cavities on the major surfaces in the insulating zone being larger in area than the cavities on the major surfaces at the perimeter of the high temperature zone and being located a further distance from the high temperature zone than the cavities at the perimeter thereof, the cavities in the insulating zone and the cavities at the perimeter of the high temperature zone being shaped and being spaced apart such that they define a frame around the perimeter of the high temperature zone and a path connecting the high temperature zone and the insulating zone, pneumatic channels extending across the insulating zone and across the path into the high temperature zone to communicate with manifold ports therein, the frame limiting the heat transfer from the high temperature zone to the insulating zone.
