Abstract

The heat exchanger ( 1 ) of the invention has exchange elements ( 2, 3 ′) and a casing ( 4 ) for accommodating the exchange elements ( 2, 3 ′). The casing ( 4 ) is formed by a plurality of walls connected together. The exchanger ( 1 ) is characterized in that the casing ( 4 ) has two L-shaped walls. The casing ( 4 ) is easier to manufacture and store.

First claim

The invention claimed is:

1. A heat exchanger having exchange elements ( 2 , 2 ′, 3 , 3 ′) and a casing ( 4 ) for accommodating the exchange elements ( 2 , 3 ′), the casing ( 4 ) formed by a plurality of walls ( 15 , 16 ) connected together, wherein the casing ( 4 ) has two L-shaped walls ( 15 , 16 ), wherein a first wall ( 15 ) has a first flap ( 15 a ) that extends in a first direction and a second flap ( 15 b ) of the first wall ( 15 ) that extends from the first flap ( 15 a ) in a second direction perpendicular to the first direction, wherein a second wall ( 16 ) has a third flap ( 16 a ) that extends in a third direction opposite to the first direction and a fourth flap ( 16 b ) of the second wall ( 16 ) that extends from the third flap ( 16 a ) in a fourth direction perpendicular to the third direction and opposite the second direction, wherein the second flap ( 15 b ) has a first turned-up edge ( 15 c ) perpendicular to the second flap ( 15 b ) that extends in the third direction for securing the first turned-up edge ( 15 c ) to the third flap ( 16 a ) and the fourth flap ( 16 b ) has a second turned-up edge ( 16 c ) perpendicular to the fourth flap ( 16 b ) that extends in the first direction for securing the second turned-up edge ( 16 c ) to the first flap ( 15 a ), wherein the first flap ( 15 a ) has a length greater than a length of the second flap ( 15 b ) and the third flap ( 16 a ) has a length greater than a length of the fourth flap ( 16 b ), wherein an inlet pipe ( 8 ) and outlet pipe ( 9 ) are connected to a single face of either one of the second flap ( 15 b ) and the fourth flap ( 16 b ),
wherein one of the second and fourth flaps ( 15 b , 16 b ) has an indentation ( 15 e , 16 e ) which is designed to come into contact with flow tubes ( 2 ), which are assembled in parallel, for a first fluid and thus to form flow channels ( 3 ) for a second fluid between the flow tubes ( 2 ), and
wherein, with the one of the second and fourth flaps ( 15 b , 16 b ) having the indentation ( 15 e , 16 e ) also having at least one orifice ( 6 , 7 ) for connecting to a flow circuit for the second fluid, the at least one orifice ( 6 , 7 ) is formed on a portion (( 15 f , 15 f ), ( 16 f , 16 f )) of the second and fourth flaps ( 15 b , 16 b ) which is separate from the indentation ( 15 e , 16 e ) in order to enable better distribution of the second fluid in its flow channels ( 3 ).
