Abstract
The present invention is directed to a heat exchanger having a divided header tank. The heat exchanger has a pair of header tanks and a plurality of pipe members, by which the header tanks are placed in fluid communication. A partitioning plate is fixedly disposed within a hollow space of one of the header tanks, so that the hollow space is divided into two chamber sections. A gap is defined between the pair of header tanks corresponding to the partitioning plate. A blocking element is disposed within the gap, so that air which otherwise would pass through the gap is blocked, and the overall heat exchange operation of the heat exchanger is improved.
Claims12
A heat exchanger comprising:
- a pair or header tanks spaced from each other, wherein each of the pair of header tanks comprises a top end portion, a bottom end portion spaced from the top end portion, and a sidewall portion connecting the top and bottom end portions, so that a hollow space is defined within each of the pair of header tanks;
- and wherein the sidewall portion of each of the pair of header tanks includes a first side and a second side which is spaced from and parallel to the first side;
- a plurality of pipe members placing the pair of header tanks in fluid communication;
- at least one partitioning member fixedly disposed within the hollow space of at least one header tank parallel to the first and second sides of the sidewall portion of each of the pair of header tanks, so that the inner hollow space of the at least one header tank is divided into at least two chamber sections, wherein at least one gap is formed between the pair of header tanks corresponding to the at least one partitioning member;
- and
- at least one resilient blocking element fixedly disposed within the at least one gap, wherein said blocking element is a U-shaped plate member having a pair of plane portions and a connecting portion which extends across the at least one gap and connects one end of each of the plane portions;
- wherein said blocking element contacts at least a pair of said pipe members.

- at least one partitioning member fixedly disposed within the hollow space of at least one header tank parallel to the first and second sides of the sidewall portion of each of the pair of header tanks, so that the inner hollow space of the at least one header tank is divided into at least two chamber sections, wherein at least one gap is formed between the pair of header tanks corresponding to the at least one partitioning member;
- and
- at least one resilient blocking element fixedly disposed within the at least one gap, wherein the at least one blocking element includes a core plate member and a pair of shell members which sandwich the core plate member;
- wherein said blocking element contacts at least a pair of said pipe members.
