A heat exchanger arrangement is provided with a housing provided with a fluid inlet and a fluid outlet and designed to be flowed through by the fluid. A heat exchanger is arranged in the housing between fluid inlet and fluid outlet and surrounded by the housing. The heat exchanger is arranged such that the fluid can flow through the heat exchanger. The housing has a seal contour. The heat exchanger is connected with form fit at a fluid inlet of the heat exchanger or at a fluid outlet of the heat exchanger to the seal contour of the housing. In a method of producing the heat exchanger arrangement, a seal surface of the seal contour of the housing is melted and pressed against a seal region of the heat exchanger at the fluid inlet of the heat exchanger or at the fluid outlet of the heat exchanger.

The first base section defines a first fastening area for securing the first leaf to a diaphragm of the preheater. The first leaf has a first elongate section extending away from the first base section and terminating at a first distal end thereof. The leaf assembly further includes a second leaf that engages a portion of the first leaf. The second leaf has a second base section. The second base section defines a second fastening area for securing the second leaf to the diaphragm. The second leaf has a second elongate section extending away from the second base section and terminating at a second distal end thereof. The supplemental leaf assembly is secured to the first leaf and slidingly engaging the second leaf.

This document describes inlet and outlet channels for a heat exchanger that provides a compact profile with consistent cooling performances among heat exchanger plates. For example, a manifold of a cooling system includes an inlet channel and an outlet channel designed to connect to multiple plates of a heat exchanger. The inlet and outlet channels include a junction portion, a connection portion, and a transfer portion. The junction portion includes opposing inclined contact surfaces that are inclined relative to a horizontal plane of the plates and mate with corresponding inclined contact surfaces of the plates. The connection portion accepts coolant hoses. The transfer portion is located between the junction portion and connection portions. The described channels of the manifold are especially useful for automotive applications that generally have tight assembly spaces.
