A heat exchanger assembly includes a first heat exchange fluid conduit and at least one fin. The first heat exchange fluid conduit defines a passageway therethrough and is configured to receive a flow of a first heat exchange fluid. At least one fin is disposed to receive a flow of a second heat exchange fluid. The fin(s) is/are coupled to the heat exchange fluid conduit at an interface that is configured to reduce accumulation of debris entrained in the second heat exchange fluid.

A heat exchanger, particularly for a heating or air conditioning system for motor vehicles, includes at least one inlet channel and at least one outlet channel and at least one collector, which has at least two metal sheets or plates abutting each other, and a flow device through which a first medium can flow, while a second medium can flow around the flow device. The first medium is distributed by an inlet channel to the collector and to the flow device and can be conducted to an outlet channel, and at least one further channel for distributing the coolant is provided, which is connected in a communicating manner via at least one opening to the inlet channel.

A heat exchanger includes: a header that extends in a first direction; and a plurality of heat transfer tubes that extend in a second direction crossing the first direction, each of which has one end connected to the header, and that are arranged in the first direction at intervals. The header includes: a header body having a tubular shape, a first member through which the one end of each of the heat transfer tubes extends, and a second member positioned between the header body and the first member in the second direction. The second member includes: a base portion that extends in the first direction, and a plurality of protruding portions that extend from the base portion toward the first member in the second direction.

A coupling device for a fluid cooling system may have a first coupling unit having a first housing, which has a first sub-housing and a second sub-housing connectable to the first sub-housing. The first sub-housing may have a first axial passage opening connectable to a first fluid line, a first signal interface and a first end face. The second sub-housing may have a second axial passage opening connectable to a second fluid line, a second signal interface and a second end face. The first sub-housing and the second sub-housing are axially connectable to one another and the passage openings are fluidically connected to one another and the signal interfaces are connected to one another. The two sub-housings may be laterally connectable to one another, so that in the laterally coupled state, the two sub-housings are arranged parallel next to one another.

A collector tube for a heat exchanger having at least one flat tube, may include a base and a cover arranged opposite the base. The base and the cover may define a longitudinal duct. The base may include at least one passage having an opening configured to accommodate the at least one flat tube of the heat exchanger. The opening may have at least one wide edge and at least one narrow edge. The longitudinal duct may have, in a cross section, a diameter that is smaller than the at least one wide edge of the opening. The at least one passage may include a collar extending away from the longitudinal duct.

A heat exchanger assembly includes a first heat exchange fluid conduit and at least one fin. The first heat exchange fluid conduit defines a passageway therethrough and is configured to receive a flow of a first heat exchange fluid. At least one fin is disposed to receive a flow of a second heat exchange fluid. The fin(s) is/are coupled to the heat exchange fluid conduit at an interface that is configured to reduce accumulation of debris entrained in the second heat exchange fluid.

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.

A plate-type heat exchanger includes heat-exchange plates which are mutually stacked and facing each other so as to define, in the space between them, at least two passage channels. The heat-exchange plates have respective entry apertures which are substantially mutually adjacent so as to define an entry conduit. The entry conduit is connected with the passage channel of the corresponding fluid through at least one orifice. The entry apertures have respective collar-like edgings. Each one of the collar-like edgings has an abutment flange which extends radially with respect to the axis of the entry apertures and is adapted to engage, by contact, the abutment flange of the collar-like edging of an adjacent heat-exchange plate.

A radiator for cooling a transformer, preferably a power transformer, or a choke, includes a plurality of plate-shaped radiator elements which are disposed parallel to one another and through which a coolant can flow in parallel. At least one elastically deformable element is provided at least between two adjacent radiator elements and is constructed in such a way that it counteracts an expansion of the radiator elements perpendicular to the surface of the radiator elements. Plastic deformation of the walls of the radiator elements can be prevented by the elastically deformable elements. A unit including a transformer or a choke and a method for producing a radiator are also provided.

Modular flow control systems include several differently-shaped structures to achieve desired flow characteristics in fluid flow. Systems include one or many plates held in desired positions by a retainer within the flow. The plates are uniquely shaped based on their position, or vice versa, to shape flow in a desired manner. The plates may fill an entire flow area or may extend partially throughout the area. Plates can take on any shape and are useable in systems installed in any type of flow conduit. When used in a PCCS upper manifold in a nuclear reactor, a chevron plate directly below the inlet divides flow along the entire upper manifold. Perforated plates allow flow to pass at ends of the PCCS upper manifold. The plates can be installed along a grooved edge during an access period and held in static position by filling the length of the PCCS upper manifold.
