Evaporator

An evaporator for a refrigerant or the like comprising:

• means defining a plurality of hydraulically parallel flow paths for a fluid to be evaporated, each flow path having first and second ends;
• an inlet header at said first ends in fluid communication thereat with each of said flow paths;
• an outlet header including an elongated outlet channel at said second ends and in fluid communication thereat with each of said flow paths;
• and
• a pair of outlets to said outlet channel at opposite ends thereof and directed away from each other so that fluid leaving said outlets will be in the form of two streams diverging from one another to reduce outlet resistance and improve the uniformity of distribution of said fluid among said flow paths.

An evaporator for use in a refrigeration system comprising:

• a plurality of tubes in hydraulic parallel and in spaced relation to one another;
• fins extending between and mounted to said tubes;
• an elongated header extending between said tubes and in fluid communication with the interior of each said tube;
• and
• two spaced ports in said header for generating two generally oppositely directed streams of fluid that provide a more uniform distribution of fluid through said tubes.

An evaporator for use in a refrigeration system comprising:

• a plurality of tubes in hydraulic parallel and in spaced relation to one another;
• fins extending between and mounted to said tubes;
• an elongated header extending between said tubes and in fluid communication with the interior of each said tube;
• two spaced ports in said header for generating two streams of fluid that provide a more uniform distribution of fluid through said tubes;
• a generally C-shaped conduit interconnecting said ports;
• and
• a tee in said conduit through which a fluid to be evaporated may be introduced into said conduit for flow to both said ports.

An evaporator for use in a refrigeration system comprising:

• an elongated header;
• two ports, one at each end of said header, said ports facing each other;
• a common conduit interconnecting said ports;
• and
• a plurality of spaced tubes extending from said header and each having an open end within said header, said open ends being disposed along the length of said header.

An evaporator for use in a refrigeration system comprising:

• a first elongated header;
• spaced facing ports to said first header, one at each end thereof;
• a first plurality of spaced tubes extending from said first header and each having an open end within said first header, said open ends being disposed along the length of said first header;
• a second elongated header;
• spaced facing ports to said second header, one at each end thereof;
• a second plurality of spaced tubes extending from said second header and each having an open end within said second header, said open ends being disposed along the length of said second header;
• and
• a pair of common conduits interconnecting one of said first header ports to one of said second header ports and connecting the other of said first header ports to the other of said second header ports.

An evaporator for use in a refrigeration system comprising:

• an inlet header including an elongated inlet channel;
• an outlet header in side-by-side relation to said inlet header, said outlet header including an elongated outlet channel;
• first and second intermediate headers in side-by-side relation, spaced and parallel to said inlet and outlet headers each said intermediate headers including an elongated channel;
• first and second rows of tubes, each tube in said first row in fluid communication with said inlet channel and said first intermediate channel, and each tube in said second row in fluid communication with said outlet channel and said second intermediate channel;
• a pair of inlets to said inlet channel at opposite ends thereof;
• a pair of outlets from said outlet channel at opposite ends thereof;
• a pair of outlets from said first intermediate channel at opposite ends thereof;
• and
• a pair of inlets to said second intermediate channel at opposite ends thereof.

An evaporator for use in a refrigeration system comprising:

• a plurality of tubes in hydraulic parallel and in spaced relation to one another;
• fins extending between and mounted to said tubes;
• an elongated header having ends facing each other spaced lengthwise of the header and a center equally spaced between said ends, with the elongated header extending between said tubes and in fluid communication with the interior of each said tube;
• and
• two spaced ports in said header wherein said ports are each closer to an end of said header than to the center of said header to provide a more uniform distribution of fluid through said tubes.

An evaporator for use in a refrigeration system comprising:

• an elongated header having ends spaced lengthwise of the header and a center between said spaced ends;
• two ports, one proximate each end of the header, with said ports being closer to the ends of the header than to the center thereof;
• a common conduit interconnecting said ports;
• and
• a plurality of spaced tubes extending from said header and each having an open end within said header, said open ends being disposed along the length of said header.
