Abstract: The present invention relates to a heat exchanger, in particular, an oil cooler for motor vehicles, constructed from trough-shaped heat exchanger plates which are stacked into one another and from turbulence inserts, having two openings for one medium and two further openings for another medium in order to form collecting ducts for the supply and discharge of the media, with flow ducts for the media being formed between the heat exchanger plates. The heat exchanger also includes flow ducts connected to the associated collecting ducts, an upper closure plate which has convexities in the region of the collecting tanks, and an intermediate plate which is provided with holes. The intermediate plate is arranged between the closure plate and the uppermost heat exchanger plate, and one of the holes, formed as a pressure equalizing opening, interacts with the upwardly aligned convexity in the closure plate to improve the internal pressure stability.

Abstract: A heat exchanger according to some embodiments includes heat exchanger plates stacked one inside the other and each having a trough-shaped edge, flow ducts located between the heat exchanger plates for heat-exchanging media, feed ducts and discharge ducts, and an attachment plate having openings for feeding and discharging the media through the attachment plate. In some embodiments, a multipart attachment plate is provided, wherein a bottom heat exchanger plate lies on an attachment plate, and another overlying attachment plate has a cutout having an edge shaped to lie against the trough-shaped edge of the bottom heat exchanger plate.

Abstract: A plate heat exchanger including a stack of heat exchanger plates and at least one connection plate having at least one opening with a flange extending from the plate around the opening, and a connector connecting a heat exchange medium to the connection plate opening for supplying the medium to or discharging the medium from the heat exchanger, wherein the connector is an injection-molded plastic part and the flange has crenellate protrusions which are deformed to mechanically fasten the connector to the closure plate. A reduced wall thickness defines a seat in the connection plate around the flange, and a seal is between the flange and the connection edge. The connector may have a cross-section at its connection to a supply or discharge line which is wider than the cross-section at the connection edge, and a seal is between the connector and the line in the wider cross-section.

Abstract: A stacked plate heat exchanger is provided. The stacked plate heat exchanger includes a first end plate having an integrated connector. The connector has a first cross sectional plane at a first port and a second cross sectional plane at a second port with the first and second cross sectional planes forming an acute angle with respect to each other.

Abstract: The invention relates to a support for articles such as ceiling slabs, roof battens, machine parts or the like. The support comprises at least two telescopic tubes or one telescopic eod in at least one tube. A first tube or the rod can be displaced by a first distance in relation to the second tube, and devices are provided to convey the first tube or the rod a further distance in relation to the second tube. Stopping devices for the tube(s) and the rod are also provided in relation to each other and end stops are provided on the tubes, or the rod, the devices for further conveyance of the first tube or the rod comprising a ratchet, rack, clamping bracket or the like which are provided with manual advance devices.
