A heat exchange assembly, which comprises a first heat exchange part, a bridge, and a second heat exchange part, wherein the bridge is at least partially located between the first heat exchange part and the second heat exchange part; the bridge comprises two holes or grooves that face the first heat exchange part and may communicate with the first heat exchange part; the bridge comprises two holes or grooves that face the second heat exchange part and may communicate with the second heat exchange part; the bridge further comprises a third interface part provided with a third interface; and the bridge has a hole and/or groove that is in communication with the third interface. Fluid communication between the two heat exchange parts may be achieved relatively conveniently by means of the bridge, and different system requirements may be achieved by means of changing the structure of the bridge, so that a system pipeline is simple, the arrangement of pipelines can be minimized between the interfaces, and the system connection is simple and convenient.

A heat exchanger (10) includes an assembly of plates (12) stacked in pairs in a longitudinal stacking direction (x) to form a heat exchanger body (14), designed for the circulation of a fluid, comprising a connection device (19) arranged at one extremity of the heat exchanger body (14) in the longitudinal stacking direction (x). The connection device (19) includes an end plate (20) and a cover (22) that can be assembled together to jointly delimit an inlet duct (24) and an outlet duct (26), respectively, to admit the fluid into the heat exchanger body (14) and discharge the fluid from the heat exchanger body (14).

A heat exchanger has first and second flow passages with a communication passage therebetween. An inlet/outlet opening in a wall of the first passage receives a one-piece inlet/outlet fitting having an inner tube and an outer ring connected by webs, the tube and ring defining inner and outer flow passages in direct flow communication with the first and second flow passages, respectively. A first end of the tube and an outer surface of the ring are provided with resilient sealing members for sealing within a bore of a coolant manifold. The ring has a planar sealing surface which is sealed to the wall of the first passage, and the second end of the inner tube extends through the first fluid flow passage and is sealed inside the communication passage. Lateral adjustment of the fitting within the inlet/outlet opening compensates for stack-up tolerance variation in the heat exchanger.

A connector for a component fitting assembly of an air conditioning system includes a substantially planar plate having a recessed portion and a slot portion. The recessed portion and the slot portion are formed in the plate to define an opening for receiving a conduit therein. A method for coupling the conduit to the connector includes the step of urging at least the portion of the conduit through the slot portion and into the recessed portion of the plate, whereby the at least the portion of the conduit is deformed to correspond with a configuration of the opening to militate against disengagement between the plate and the at least the portion of the conduit disposed in the opening of the plate.

A brazed heat exchanger includes plates that are stacked or nested to define flow channels for multiple media. Inserts are arranged within at least some of the flow channels. Two different braze alloys having compositions based on different metals are used to form braze joints between the plates and the inserts. In some cases, a copper-based braze alloy is used for joints corresponding to flow channels for one of the media in order to provide high pressure-resisting strength to those flow channels, while an iron-based braze alloy is used for joints corresponding to flow channels for another of the media where dissolved copper is undesirable.

A heat exchanger unit is utilized for heating service water in a heating installation. The unit includes a plate heat exchanger a first connector, attached to a first fluid connection point of the heat exchanger, and a second connector, fastened to the heat exchanger. The first and second connectors each include at least one base element. The base element of the first connector and the base element of the second connector have an identical configuration. Each base element includes at least two distinct flow ducts.

A stub connection for a heat exchanger that is arranged in a housing and has a stack including plates and fins. The housing consists of housing parts which can be joined together, and at least one first stub for a first heat-exchanging medium being integrated directly into the housing. The stub connection also includes at least one second stub for a second heat-exchanging medium that extends to outside the housing. The at least one second stub is configured for the connection of a line and is integrated directly or indirectly into the housing.

The invention relates to a connection interface (20) for a connection assembly (10) for connecting refrigerant tubes in a cooling assembly of a motor vehicle electrical storage device, the connection assembly (10) comprising at least one flange (18) made integral with a heat exchange member (4), said connection interface (20) being arranged at end portions (24) of refrigerant fluid tubes to be connected to said heat exchange member, characterised in that the connection interface (20) comprises a first portion (50) integral with the end of each of the tubes (12) and a second portion (52) mounted freely around the tubes, the second portion comprising openings (64, 66) for passing the tubes dimensioned to allow a clearance for relative movement therebetween of the two portions (50, 52) of the connection interface (20), at least in a plane perpendicular to a direction of elongation of the end portions of the tubes, the connection interface (20) being configured to engage with a securing member (36) capable of setting the position of the two portions relative to each other.

A support and connection device is for an operating group of a vehicle. The support and connection device is configured for supporting and for fluidic connection with an operating device in turn included in the operating group. The support and connection device identifies a vertical axis and two longitudinal axes and includes at least one plate-shaped unit in which, in the vertical direction, there is at least one mouth for the passage of a working fluid. The plate-shaped unit includes an upper laminar element, a lower laminar element reciprocally stacked along the vertical axis and a hollow space between them. The at least one mouth for fluid passage is defined laterally by a fluid mouth wall constituted by the reciprocal engagement of an upper mouth rim included in the upper laminar element and by a lower mouth rim included in the lower laminar element.

The invention relates to a temperature control device, in particular a cooling device, for an electrical component prone to releasing heat during operation, in particular for an electrical energy storage module, said device comprising an upper plate and a lower plate that is assembled with said upper plate to jointly form a plurality of ducts for the circulation of a heat transfer fluid, in particular a refrigerant fluid, in particular a fluid selected from the refrigerant fluids R134a, R1234yf and R744; in said device, the ducts are grouped into groups of ducts, the ducts of a group extending substantially parallel to one another at a predetermined ‘intra-group distance’ between neighboring ducts; two groups of ducts in which the fluid flows in the same direction being separated from each other by at least one group of ducts in which the fluid flows in the opposite direction, wherein the device comprises a connector (550).
