Abstract: A device for filling and maintenance of a system with a battery that is cooled by a coolant is disclosed. The device includes a control arrangement that, for a first filling of the system with the coolant: checks a system path for leakages via a leakage-checking arrangement; in the absence of leakage, fills the system with coolant via a coolant reservoir; flushes the system with coolant such that the coolant circulates along the system path through the system and the device; checks a quality of the coolant via an analysis arrangement during flushing, and cleans the coolant via a cleaning arrangement; and completes the first filling when the quality lies above a predetermined value range.

Abstract: A fluid management module for cooling an electric energy store by immersion cooling is disclosed. The fluid management module includes a fluid path for a cooling medium comprising an inlet connection and an outlet connection. A heat exchanger and a filter device are arranged in the fluid path. A valve device is arranged in the fluid path between the inlet connection and the outlet connection. A service inlet connection communicates with the fluid path between the valve device and the outlet connection and a service outlet connection communicates with the fluid path between the inlet connection and the heat exchanger, for fluidically connecting the fluid path with a service unit containing a cooling medium reservoir for the cooling medium.

Abstract: A method for filling a cooling circuit of a motor vehicle with a coolant may include filling the cooling circuit with ion-free water in a water filling operation, leaving the ion-free water in the cooling circuit for a water duration of action in a water operation of action, displacing the ion-free water out of the cooling circuit via filling the cooling circuit with a passivating agent in a passivating operation, rinsing the cooling circuit with ion-free water such that the ion-free water at least dilutes the passivating agent in the cooling circuit and a liquid including at least one of the ion-free water and the passivating agent remains in the cooling circuit in a rinsing operation, displacing the liquid out of the cooling circuit via filling the cooling circuit with the coolant in a coolant filling operation, and/or fluidically sealing the cooling circuit towards an outside in a sealing operation.

Abstract: The present invention relates to a method for filling a cooling circuit (2) of a motor vehicle (3) with a coolant (4). A simple filling of the cooling circuit (2) with coolant (4) and an increased operational safety are achieved in that the cooling circuit (2) is initially filled with ion-free water (13) and thereafter with a passivating agent (16), and wherein thereafter the cooling circuit (2) is rinsed with ion-free water (13) and subsequently filled with the coolant (4). The invention, furthermore, relates to a system (1) for filling a cooling circuit (2) of a motor vehicle (3) with coolant (4).

Abstract: A heat exchanger component of a temperature control system of an electrical energy store may include a carrier material and at least two layers. The at least two layers may include a first layer composed of an electrically insulating material and a second layer that may facilitate temperature control via at least one of cooling and heating the electrical energy store.

Abstract: A heat exchanger for a motor vehicle includes first fluid lines of a flexible material, through which a first fluid (F1) flows, and a holding structure with holding elements. The first fluid lines and the holding elements form a woven structure. The holding elements are in a thread-like manner and extend along a second direction of extension (R2), at right angles to a first direction of extension (R1). The heat exchanger, through which a second fluid (F2) flows, is separated from the first fluid (F1). The woven structure includes a first and second partial woven structures and are formed separately. The first partial woven structure and the second partial structure are arranged so that the second fluid (F2) flows through the woven structure space, formed between the two partial woven structures. The first and the second partial woven structures are at an angle relative to one another.

Abstract: The application relates to a heat exchanger and a connecting system for the heat exchanger. This subject matter includes a housing formed by a top part and a bottom part and a first connecting element and a second connecting element connected to these top and bottom parts. Specific embodiments of the subject matter are shown in which the connecting elements connect the housing top part and bottom part by a positive and/or material connection. The advantages of each embodiment over prior approaches are too numerous to include in this abstract, but will be apparent to one of ordinary skill in the art when reviewing the full specification.

Abstract: The invention relates to a heat exchanger for a motor vehicle, comprising a heat exchanger block and at least one collection box with a tube plate. The heat exchanger block is made of a plurality of adjacent tubes and corrugated rib elements arranged between the tubes, and one of the end regions of the tubes is received in the tube plate of the collection box in a fluid-tight manner. The tube plate of the collection box is made of plastic and is injection molded onto the heat exchanger block. A spacer element through which the tubes are guided is arranged between the tube plate of the collection box and the heat exchanger block, and the corrugated rib elements are spaced from the tube plate of the collection box by the spacer. The invention further relates to a method for producing a heat exchanger.

Abstract: The invention relates to a heat exchanger with a first and a second collecting tank, with at least one tube arranged between the two collecting tanks, each having a fluid inlet and a fluid outlet. At least one tube end is in fluid communication with a collecting tank and is connected to the collecting tank via a form-fitting and/or integrally bonded connection, wherein the opening is surrounded by an opening edge.
