Vehicle-loaded parallel flow type heat exchanger

A heat exchanger comprising:

• a pair of header tanks placed in parallel to each other in a plane;
• a row of parallel tubes placed in said plane and connected at opposite ends to said header tanks;
• a plurality of partitions provided within said header tanks to divide each header tank into a plurality of compartments along the length of said each header tank thereby forming a plurality of refrigerant passages each consisting of a plurality of multitube paths each having a plurality of said parallel tubes;
• and
• a longitudinal partition provided within each of said header tanks to form a chamber separate from said plurality of partitions which communicates in parallel with said refrigerant passages through ports formed thereon whereby refrigerant is distributed into said plurality of refrigerant passages to provide reduced flow resistance.
