Abstract:
1. An exchange apparatus comprising: a perfluorinated thermoplastic housing; a plurality of perfluorinated thermoplastic hollow tubes having a geometry selected from the group consisting of twisted tubes and non-circumferential tubes, each of said hollow tubes having a first end portion and a second end portion and hollows passing therebetween; said first end portions of said perfluorinated thermoplastic hollow tubes being fusion bonded at least at a periphery of said perfluorinated thermoplastic hollow tubes through a perfluorinated thermoplastic resin to form a first unified terminal end block in which the end portions of said perfluorinated thermoplastic hollow tubes are fluid tightly bonded together in a fused fashion with the perfluorinated thermoplastic resin; said second end portions of said perfluorinated thermoplastic hollow tubes being fusion bonded at least at a periphery of said perfluorinated thermoplastic hollow tubes through a perfluorinated thermoplastic resin to form a second unified terminal end block in which the end portions of said perfluorinated thermoplastic hollow tubes are fluid tightly bonded together in a fused fashion with the perfluorinated thermoplastic resin said first unified terminal end block and said second unified terminal end block having through hole communication with the hollows of the unbonded portions of said perfluorinated thermoplastic hollow tubes; said first unified terminal end block having a first fluid inlet connection to supply a first fluid to said perfluorinated thermoplastic hollow tubes and said second unified terminal end block having a first fluid outlet connection to remove said first fluid from said perfluorinated thermoplastic hollow tubes; said perfluorinated thermoplastic housing fusion bonded by said perfluorinated thermoplastic resin to form a single entity consisting solely of fusion bonded perfluorinated thermoplastic materials; said perfluorinated thermoplastic housing having first housing port wherein a second fluid enters the exchange apparatus and a second housing port wherein said second fluid exits the housing.
