Abstract
A vehicular heat exchange module, including first, second and third heat exchanger, with two of the heat exchangers being a radiator a charge air cooler. The heat exchangers include a core having a plurality of flat tubes with cooling ribs therebetween. At least one of the heat exchangers has a gradation whereby the one heat exchanger has a portion with a reduced thickness in the flow direction defining a free space, and at least one part of at least one of the other heat exchangers occupies the free space.
Claims14
A vehicular heat exchange module for exchanging heat with cooling air moving in a flow direction, comprising:
- a first heat exchanger;
- a second heat exchanger comprising a radiator;
- and
- a third heat exchanger comprising a charge air cooler;
- wherein
- said heat exchangers include a core having a plurality of flat tubes with cooling ribs therebetween,
- at least one of the heat exchangers has a gradation whereby said one heat exchanger has a portion with a reduced thickness in the flow direction defining a free space, and
- at least one part of at least one of the other heat exchangers occupies said free space.
A heat exchanger for use with an arrangement of heat exchangers in a vehicle, comprising a core having at least one row of longitudinally extending flat tubes with cooling ribs arranged between said tubes, said tubes and ribs disposed to be traversed by cooling air, said core having a gradation created by one or more of:
- flat tubes arranged in a single row with different cross-sectional sizes, and
- several rows of flat tubes with a different number of flat tubes;
- wherein the flat tubes in the rows have the same or different cross-sectional sizes
- whereby the gradation runs in the longitudinal direction of flat tubes.
