Embodiments disclose a flexible connection of a metallic extruded profile to a connecting body for cooling electrical components. A heat exchanger for an electrical component comprises a metallic extruded profile having at least one channel for a cooling agent to flow through, the metallic extruded profile including an outer circumferential surface and a first end, a non-metallic connecting body including an accommodating region for receiving the first end of the metallic extruded profile at a first opening corresponding to a cross-section of the first end, the first opening having an inner circumferential surface, and a bonding layer between the outer circumferential surface of the first end received in the accommodating region and the inner circumferential surface of the opening. The bonding layer is configured to establish a mechanically flexible bond between the metallic extruded profile and the non-metallic connecting body. Embodiments further disclose a production method for a heat exchanger.

The present disclosure relates to a fin heat exchanger, including a header, a set of tubes fluidly coupled to the header, and a mount configured to engage with and disengage from the set of tubes. The mount includes a fin section configured to extend between adjacent tubes of the set of tubes in an engaged mount configuration, and configured to be separated from the set of tubes in an unengaged mount configuration.

A heat exchanger assembly includes a frame, a plurality of tubes, and a first bumper clip attaching at least a first tube of the plurality of tubes to the frame. The first tube defines a first exterior dimension and the first bumper clip defines a first tube slot defining a first tube slot dimension that is less than the first exterior dimension of the at least first tube.

An arrangement has a housing, which has a receptacle or an opening, and a cylindrical insert, which is mounted in the receptacle or opening via at least one interference fit. The insert has a peripheral groove, and therefore the insert is both fastened against the housing and sealed against the housing in a liquid- and/or gas-tight manner by way of material of the insert and/or housing that has been pressed into the groove during the assembly. The material of the insert and/or of the housing is displaced in the case of an interference fit. The groove provides a defined location to which the material can preferably flow. After the assembly has been concluded, the insert is locked against the housing by the material located in the groove. At the same time, the material acts as a seal between the insert and the housing. A separate seal in the region of the press fit becomes dispensable.

The installation means for a device for treating, in particular humidifying and/or cleaning, a net fluid, in particular a gas, by means of a working fluid, in particular a liquid, and particularly for cooling water vapor by means of spray water and/or drip water, is provided with at least one installation package (10) of several square, waved mat elements (12) being arranged in an overlying or adjoining manner Adjacent mat elements (12) are mechanically connected to each other by pin-hole-arrangements in which pins (42) protruding from the one mat element (12) and each comprising a free end are inserted in receiving openings (34) formed in the other mat element (12). The receiving openings (34) each comprise an opening edge (36) from which a flexible clamping tongue (38) protrudes into the receiving opening (34). Each receiving opening (34) comprises an area size limited by the free end of the at least one clamping tongue (38) and the region of the opening edge (36) opposite to said end, or by the free ends of several, in particular two or three clamping tongues (38), wherein the area size (40) being smaller than the cross-section of the pin (42) in the state of the pin (42) in which the pin (42) is received by the receiving opening (34), and in which the at least one clamping tongue (38) is bend with its free end to the free end of the pin and abuts against the pin (42).

A cooling mechanism of high mounting flexibility includes a heat sink including a heat sink body defining an accommodation portion and position-limit sliding grooves and stop blocks fastened to the heat sink body, heat pipes positioned in the position-limit sliding grooves and stopped against the stop blocks, each heat pipe having a hot interface accommodated in the accommodation portion and an opposing cold interface positioned in one position-limit sliding groove, heat transfer blocks each defining a recessed insertion passage for accommodating the hot interfaces of the heat pipes and an opposing planar contact surface for the contact of a heat source of an external circuit board, and an elastic member elastically positioned between the heat sink and the heat transfer blocks.

A support assembly for attaching a heat exchanger to a frame of a machine. The support assembly including a clip having one or more attachment features for attaching to the frame and a support member disposed between a first fin portion and a second fin portion of the heat exchanger. The support member disposed between the clip and the tube member to at least partially surrounds a perimeter of the tube member and form a seal therewith.

A support assembly for attaching a heat exchanger to a frame of a machine. The support assembly includes a clip configured to at least partially surround a perimeter of a tube member of the heat exchanger. The clip includes a first end portion and a second end portion configured to engage the first end portion to hold the support assembly around the tube member in a closed position. The first end portion includes a laterally-extending projection and a laterally facing surface spaced apart from the projection by a recessed area. The second end portion defines a recess configured to receive a portion of the projection.

An exhaust gas heat exchanger may include a housing and a heat exchanger block arranged therein, the heat exchanger block including tube plates and a tube bundle having a plurality of flat tubes held at longitudinal ends of the flat tubes in rim holes formed in a complementary manner thereto in the tube plates. A first flow path for exhaust gas may extend in the flat tubes, and a second flow path for coolant may extend around the flat tubes and within the housing. The housing may include a plurality of latching contours, which interact with a plurality of counterpart latching contours arranged on an associated tube plate to fix the tube plates and the heat exchanger block on the housing.
