A heat exchanger including a corrugated heat transfer sheet having a first surface and a second surface on opposite sides thereof, a first flow channel for a first fluid flow in a first flow direction parallel to a longitudinal direction, and a second flow channel for a second fluid flow in a second flow direction parallel to the longitudinal direction, the second flow direction being opposite to the first flow direction. The heat exchanger includes a channel dividing system which provides the first flow channel and the second flow channel on opposite sides of the corrugated heat transfer sheet such that the first fluid flow is adapted to be in contact with the first surface, and the second fluid flow is adapted to be in contact with the second surface.

The application relates to a system for using the waste heat of an internal combustion engine through the Clausius-Rankine cycle. Such system prevents operating medium from the Clausius-Rankine cycle from leaking into combustion air or exhaust air. The system has a first flow channel formed by at least one first limiting component and a second flow channel formed by at least one second limiting component. The system has a fluid-conducting connection to the surroundings or to a receiving chamber from the first limiting component and preferably from the second limiting component, so that in the event of a leak the operating medium is conducted into the surroundings or into the receiving chamber.

An apparatus is provided. The apparatus includes a heat exchanger providing heat transfer between a first medium and a second medium. The apparatus also includes a movable aperture integrated onto a face of the heat exchanger and regulating a flow of the first medium based on a position of the movable aperture. The apparatus further includes an actuator controlling the position of the movable aperture

A heat exchanger has at least one inlet and outlet to permit circulation of refrigerant therethrough. Each heat exchanger includes a plurality of thin sections of material arranged between a pair of thin flat outer plates. Each of the thin sections of material is comprised of parallel flow paths, allowing for the refrigerant to flow through the inlet, then from one section to the next, and finally out the outlet. The arrangement of the sections of parallel flow paths allows for the refrigerant to come into contact with the majority of the inside wall of the outer plates, allowing for maximum heat exchange. In use for cooling liquids, the heat exchangers are arranged within a frame and brought into contact with the liquid to be cooled. When the heat exchangers are used to cool liquid sufficiently to produce ice crystals, a rotating scraping device sweeps across the surface of the heat exchanger, removing any ice crystals that have formed.

This disclosure describes an improved heat transfer system for use in reaction vessels used in chemical and biological processes. In one embodiment, a heat transfer baffle comprising two sub-assemblies adjoined to one another is provided.

A heat exchanger (1) includes a top plate (2) and a bottom plate (3), wherein between the top plate (2) and the bottom plate (3) two heat exchanger stacks (4,7) are provided, wherein the heat exchanger stacks (4,7) are separated by a separating plate (6). The underlying problem of the present disclosure is to provide a heat exchanger (1) which can be adapted easily. This problem is solved by a heat exchanger (1), wherein first heat exchanger plates (5) forming the first heat exchanger stack (4) differ from second heat exchanger plates (8) forming the second heat exchanger stack (7).

An improved double-wall heat exchanger in which the safety leak space between heat exchange surfaces forming channels for the fluids exchanging heat is filled with a heat transfer medium with improved thermal conductivity in comparison to air. Pressure responsive rupture points allow release of the heat transfer medium and the heat exchange fluid in the event of failure of one of the containment surfaces. Metal-to-metal heat transfer points are dispersed in the gap to further enhance heat transfer between the hot and cold heat exchange fluid streams.

A thermal management module comprising a heat exchanger and an expansion valve assembly is disclosed. The heat exchanger includes a plurality of first plates and a plurality of second plates disposed between two end plates. The first and second plates are alternatingly arranged in a stacked relationship. A divider plate is disposed between one of the first plates and an adjacent one of the second plates to divide the heat exchanger into a first portion (e.g., internal heat exchanger) and a second portion (e.g., chiller). When in the stacked relationship, the plates define at least a first flow path for a relatively high-pressure, high-temperature first fluid from a first circuit (e.g., a liquid refrigerant), a second flow path for a relatively low-pressure, low-temperature first fluid from the first circuit (e.g., liquid refrigerant), and a third flow path for a second fluid from a second circuit (e.g., coolant).

A heat exchanger for a vehicle heat management system comprising a first cooling loop and a second cooling loop which is separate from the first cooling loop. The heat exchanger is configured to enable a thermal coupling of the first cooling loop and the second cooling loop. In a coupled condition, the first cooling loop, the second cooling loop and the heat exchanger are configured such that heat can be dissipated from one or more vehicle elements of a vehicle to the first cooling loop and can be further dissipated from the first cooling loop to the second cooling loop via the heat exchanger. The heat exchanger is configured to electrically isolate the first cooling loop from the second cooling loop.
