A heat exchanger plate for use in a plate package for a heat exchanger device is disclosed. The plate has a geometrical main extension plane (q) and a circumferential edge portion, the circumferential edge portion having a curved upper portion, a substantially straight lower portion and two opposing side portions interconnecting the upper and the lower portions. An upper porthole is arranged in an upper section of the heat exchanger plate and located at a distance from the upper portion of the circumferential edge portion thereby defining an upper intermediate portion. The upper intermediate portion includes the shortest distance (d2) between a centre of the upper porthole and the upper portion of the circumferential edge portion. The heat exchanger plate further comprises an upper flange having an extension along the upper portion of the circumferential edge portion. The upper flange has a length (L2) as seen in a direction transverse the shortest distance (d2), being 200-80% of the diameter (D2) of the upper porthole and more preferred 180-120% of the diameter (D2) of the upper porthole. Further, a plate package is disclosed and also a heat exchanger device using such heat exchanger plate/plate package.

The present invention relates to a heat exchanger apparatus for a combustion engine. The apparatus comprises a heat exchanger comprising at least one magnetic component; and an induction heater positioned adjacent at least one magnetic component of the heat exchanger. The induction heater is connectable to a power supply to provide inductive heating to the heat exchanger.

A crimping frame or crimping base for a charge air cooler may include a circumferential raised rim including a plurality of crimping slots. The plurality of crimping slots may each include two longitudinal sides and two narrow sides. The two longitudinal sides may be disposed opposite one another and may extend parallel to the rim. The two narrow sides may be stiffened via a bent reinforcement. The bent reinforcement and the rim may be structured as a single piece.

Methods, apparatus and systems using heat exchanger reactors to form polymer derived ceramic materials, including methods for making polysilocarb (SiOC) precursors.

A water block assembly includes first and second water block units having respective first and second fluid conduits. The second water block unit is stacked on the first water block unit. The second fluid conduit operates either in parallel with the first fluid conduit or fluidly independent therefrom, such that cooled fluid is fed to the first and second fluid conduits. The first water block unit includes a first base portion and a first cover portion disposed on and affixed to the first base portion. The first cover portion defines a first fluid inlet and a first fluid outlet of the first fluid conduit. The second water block unit includes a second base portion and a second cover portion disposed on and affixed to the second base portion. The second cover portion defines a second fluid inlet and a second fluid outlet of the second fluid conduit.

A heat transfer plate includes a heat transfer area provided with a heat transfer pattern comprising elongate alternately arranged heat transfer ridges and valleys, a respective top portion of the ridges extending in a top plane and a respective bottom portion of the valleys extending in a bottom plane. The heat transfer ridges comprise ridge contact areas within which the ridges are arranged to abut an adjacent first heat transfer plate. Within at least half of the heat transfer area, the top portions of the ridges have a first width w1, and the bottom portions of the valleys have a second width w2, w1≠w2. The top portion of a number of first heat transfer ridges of the heat transfer ridges, within a respective first ridge contact area of the ridge contact areas, has a third width w3, wherein, if w1>w2 then w3<w1, and, if w1<w2 then w3>w1.

A shell and plate heat exchanger includes a shell forming an internal space, and a plate stack housed in the internal space. A plurality of refrigerant channels communicate with the internal space, and a plurality of heating medium channels are blocked from the internal space. Each of the refrigerant channels is adjacent to an associated one of the heating medium channels with heat transfer plate interposed between. Each of the heat transfer plates includes a first communication hole that communicates with the heating medium channels to introduce the heating medium, a second communication hole formed below the first communication hole that communicates with the heating medium channels to emit the heating medium, and a guide crossing between the first and second communication holes to guide the heating medium that has flowed into the heating medium channels from the first communication hole toward side portions of the heat transfer plate.

A plate heat exchanger arrangement, which includes at least a first plate pack and a second plate pack arranged adjacent to each other inside the outer casing, and the first plate pack has a diameter, defined by the outer edges of the heat exchange plates, which is greater than a diameter of the second plate pack.

A plate heat exchanger with two heat exchange plates forming a channel system between the heat exchange plates, the channel system being sealed by a sealing member. The channel system includes a support member, the support member is arranged at a distance from the sealing member and a support member material is different from a material of a heat exchange plate.

A heat exchanger for a motor vehicle includes a seal and a core. The core includes a first groove formed in a first side and a second groove formed in an opposing second side. The first groove and the second groove are each configured to receive a portion of the seal to secure the seal to the core. The seal includes a cross member and a pair of uprights extending from opposing ends of the cross member, wherein the cross member and the uprights each include a sealing element. The uprights further include a rail extending from the upright and configured to be received in the groove of the core. The core further includes an integrated shear panel formed at opposing ends thereof.
