AI Technical Summary
Technical Problem
Existing heat exchangers face challenges in reliably sealing the ends of longitudinal tubes due to complex inner contours, leading to low production tolerances and increased production costs.
Method used
A recess is formed in the bottom shell of the longitudinal tube to accommodate the end plate, allowing for greater positional and size deviations, and a side element with a collar is used to enhance sealing and brazing, reducing material thickness and production costs.
Benefits of technology
This design allows for increased production tolerances, reduces waste and costs, and provides a more durable and efficient sealing mechanism, improving the overall production and performance of the heat exchanger.

Abstract
A heat exchanger for exchanging heat between two separate fluids is provided, containing two longitudinal tubes, extending longitudinally, forming a distributing tube and collecting tube, which are spaced apart laterally, and numerous lateral tubes, extending laterally, which are adjacent to one another longitudinally, and connect the two longitudinal tubes for fluid exchange, wherein at least one of the longitudinal tubes is made of two parts that separate laterally, one of which forms a lower shell while the other forms an upper shell, both of which extend longitudinally, and fit together laterally, wherein the lower shell has a hole for each lateral tube, into which they can be inserted, and wherein at least one of the longitudinal tubes is sealed by an end plate on at least one end.
