An elongated flattened tube () includes a pair of dimples () spaced from an end () of the tube () to limit an insertion depth of the end () of the tube () into a tube slot () of a header () in a heat exchanger.

Tube feature for limiting insertion depth into header slot

A highly efficient parallel flow evaporator is provided by combining a pair of identical units (10), (12) wherein each includes a pair of identical, parallel, spaced headers (40) each having slots (44) receiving the ends of identical flattened tubes (22). Identical tanks (42) are bonded to each of the headers (40) and each has an identical central flat surface (52) and an identical, centrally located port (60). Fins (26) extend between adjacent tubes (22) in each unit (10), (12) and an inlet/outlet fixture (32) is bonded to the flat surfaces (52) of one pair of tanks (42) defined by adjacent tanks (42) of both of the units (10),(12). A cross-over fixture (30) is bonded to the flat surfaces (52) of the other pair of tanks (42) defined by the remaining tanks (42) of both of the units (10),(12). The invention minimizes the number of geometrically different parts, provides an improved distributor (140) for refrigerant, provides an improved inlet passage (108) that provides a uniform stream of refrigerant to the distributor (140) and provides for the direction of refrigerant emanating from the cross-over fixture (30) in a direction parallel to the tubes (22) for improved uniformity.

High efficiency, small volume evaporator for a refrigerant

The heat exchanger having a pair of elongated, tubular headers 10, 12 with tubes 14 extending between the headers 10, 12 and in fluid communication with the interiors thereof. Opposed slots 32, 34; 34, 52; 34, 56, 58; extend generally transverse to the length of the tubular headers 10, 12 and a baffle piece 26, 26', 26', 26'' and 26'' located in such slots.
