HEAT EXCHANGER COMPRISING A CORE OF TUBES

摘要

The invention concerns a heat exchanger (1) comprising an inlet tank (2), having a fluid inlet (4),and an outlet tank (3), having a fluid outlet (5),and a core (6) of tubes (7, 8) joining said inlet tank (2) and said outlet tank (3) together and creating a plurality of fluid flow paths (P1) from said inlet tank (2) to said outlet tank (3), wherein said tubes (7, 8) belong to a primary and a secondary group of tubes(7, 8). According to the invention said inlet tank (2) and said outlet tank (3) have header plates(9, 10), which form core interfaces and comprise throughout identical tube insertion orifices for both the primary group of tubes (7) and the secondary group of tubes (8).Further, the tubes being a member of the primary group are base tubes (7)and the tubes being a member of the secondary group are adaptation tubes (8), which differ from the base tubes (7) and a reused to locally change properties of the heat exchanger (1) in critical areas of the heat exchanger (1).

主权项

1. A heat exchanger comprising one inlet tank, having a fluid inlet for a fluid, and one outlet tank, having a fluid outlet for said fluid, and a core of tubes joining said one inlet tank and said one outlet tank together and creating a plurality of fluid flow paths for said fluid from said one inlet tank to said one outlet tank, wherein said tubes belong to a primary and a secondary group of tubes,
wherein said one inlet tank comprises a first header plate, which forms a core interface of said one inlet tank, wherein said one outlet tank comprises a second header plate, which forms a core interface of said one outlet tank, wherein said first and second header plates comprise throughout identical tube insertion orifices for both the primary group of tubes and the secondary group of tubes, and wherein the tubes being a member of the primary group are base tubes, and the tubes being a member of the secondary group are adaptation tubes, which are designed differently than the base tubes of the primary group and are used to locally change properties of the heat exchanger in critical areas of the heat exchanger.
