Abstract

Improvements in heat exchangers, consisting of a block of tube fins, a water box bottom and a water box cover, especially for vehicles, with passages for the tubes being provided at the bottom of the water box, characterized by the fact that the tubes are widened once entered into the fund and because the amount of a first characteristic value K1 **(See formula)** is in the field between 1,2 and 8 where L = Contact length between tube R and pitch D (mm) x = area of L that is still in the area of the bottom itself (AB) (mm) y = part of the passage that stands out over the thickness of the bottom SB (mm) SB = bottom wall thickness (primitive state) (mm) SB = wall thickness of the antea tube of the widening (mm) (see graph) = tensile strength of the bottom material (Kp.mm -2) (see graph) = tensile strength of the tube material (kp.mm -2).
