A heat exchanger may include a block for separately conducting first and second fluids, and a box. The block may have flat tubes through which the first fluid is flowable and each of which may have a narrow tube side and a wide tube side. The box may have a base, the flat tubes being guided into the base via corresponding through-openings in the base. Each through-opening may have at least one raised edge, with at least one narrow edge side and at least one wide edge side, surrounding the corresponding flat tube. The wide edge side may be higher than the narrow edge side. The two may transition into one another via an inclination with a recess that may have a height lower than that of the narrow edge side. A contact surface edge may have a height lower at the recess than at the narrow edge side.

Heat exchanger

An exhaust gas cooler may include a plurality of stacked disc pairs. A first flow chamber for a coolant flow may be disposed between two discs of at least a first disc pair of the plurality of disc pairs. A second flow chamber for an exhaust gas flow may be disposed between two second disc pairs of the plurality of disc pairs arranged mutually adjacent with respect to one another. The plurality of stacked disc pairs may include at least one coolant inlet and at least one coolant outlet. The first disc pair may include a plurality of coolant inlets and a plurality of coolant outlets surrounding an edge of the first disc pair to facilitate peripheral edge cooling.

Exhaust gas cooler

A method for closing a fillable collecting tank, in particular a fillable collecting tank of a heat exchanger for storing a fluid, having walls forming the collecting tank, wherein one of the walls is formed as a baseplate having openings for receiving pipes, wherein a filling opening for adding the fluid is provided in one of the walls, wherein the filling opening can be closed by the provision of a closure element that can be inserted into the filling opening or can be placed onto the filling opening after the fluid has been added to the collecting tank. A heat exchanger is also provided.

Method for closing a collecting tank

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.

Heat exchanger having additional refrigerant channel

The invention relates to a plate-shaped heat exchanger for a cooling device comprising at least one heat exchanger package, in particular for a motor vehicle, consisting of a plurality of openings for accommodating a pipe conducting a coolant, wherein each opening is surrounded by an passage and a plurality of projections are distributed between the passages for the heat exchange with the medium to be cooled. In order to allow a high performance increase of a cooling device, yet a low increase in pressure loss of the charge air, a plurality of projections are arranged around an passage, wherein the projections have a shape that assures deliberate heat conduction from the projections to the passage.

Plate-shaped heat exchanger for a cooling device comprising at least one heart exchanger package

The invention relates to a heat exchanger, in particular, an evaporator (), in particular for a motor vehicle air-conditioner, with a number of closely arranged refrigerant tubes and at least one cold reservoir (), in which a refrigerant medium is provided. The evaporator () comprises two parallel regions (' and&#x2033;) running across the total width, the first region (V) corresponding to a conventional evaporator in design, the cold reservoir () being arranged in a separate second region (&#x2033;), through which at least a partial flow of refrigerant can flow which also flows through at least a part of the first region (&#x2032;) and the first and the second region are connected to each other by at least one overflow opening ().

Heat exchanger in particular with cold reservoir

The invention relates to a heat exchanger, in particular an evaporator (), with a plurality of refrigerant-carrying pipes () which are arranged next to one another and end in at least one collecting vessel (), and with at least one cold accumulator (), in which a cold accumulating medium is provided, wherein the evaporator () has two regions arranged parallel to each other, a first region (') and a second region (&#x2032;), and the cold accumulator () is arranged in the second region (&#x2032;). In this case, the refrigerant-carrying pipes () of the first and second regions (&#x2032;) are arranged in line with one another and have a width corresponding to one another (b, b, b), and the first and second regions () have common, continuous corrugated rib.
