Abstract

A heat exchanger comprises a first heat exchange row (10) and a second heat exchange row (20), and also comprises a fluid connection element (40; 40'; 40"; 40‴; 40ʺʺ) that connects a first row distributor (11) to a second row distributor (21). The fluid connection element is an element (40) which is fixedly connected to the lateral walls (11a, 21a) of the first row distributor (11) and of the second row distributor (21) and in which a plurality of conduits (41) is formed that fluidically connect the first row distributor (11) to the second row distributor (21), or is an element (40'; 40"; 40‴; 40ʺʺ) which is fixedly connected at the top to ends (11e, 21e) of the first row distributor (11) and of the second row distributor (21) and in which a conduit (41'; 41"') is formed that fluidically connects the first row distributor (11) to the second row distributor (21).
