The disclosure relates to a plate heat exchanger in a sealed design, with a stacked arrangement comprising a front-side and a rear-side end plate, wherein at least one end plate is constituted as a connection plate, heat exchanger plates which are arranged and stacked between the front-side and the rear-side end plate, in such a way that cavities for accommodating a plurality of heat exchanger media are formed between the heat exchanger plates, and sealing elements which are disposed to seal the cavities, and a clamping device, configured to exert an external clamping pressure on the stacked arrangement for the tensioning, wherein the clamping device is formed to encompass the stacked arrangement in a form-fit manner at least in sections, namely at least in a corner region of the stacked arrangement.

A chemical reactor including: a plurality of heat exchange plates which between them define reaction compartments, in which reactor each heat exchange plate includes two walls between them defining at least one heat exchange space, the respective walls being fixed together by joining regions, and the reactor also comprises at least one injection device for injecting substance into the reaction compartments, said substance-injection device passing through the heat-exchange plates in respective joining regions thereof. Also, a chemical reaction process that can be carried out in this reactor.

A heat exchanger for transferring heat between a gaseous first fluid and a liquid second fluid may include a plurality of hollow pipes extending transversely through a first fluid path for conducting the first fluid. The plurality of pipes may be coupled externally to a plurality of cooling fins arranged in the first fluid path. The plurality of pipes may internally define a second fluid path for conducting the second fluid. The plurality of pipes and the plurality of cooling fins may be arranged stacked on one another in a stacking direction to define a cooler block. The cooler block may include two side parts extending along two outer sides of the cooler block facing away from one another in the stacking direction. At least one tension rod may fixedly connect the two side parts and be configured to transmit a tensile force in the stacking direction.

A sheet material is for heat exchange between a first and a second fluid, thus inducing a phase change in the fluids. The sheet material is folded to form a plurality of slits, which slits constitute the flow paths of the fluids. The slits for the first fluid, through at least one seal, are closed, and the slits for the second fluid, through at least one seal, are fully or partly open for fluid outflow.

A radiator includes a main body, two connecting members and two taps. The two connecting members are disposed on opposite sides of the main body. Each of the two taps is rotatably connected to one of the two connecting members, such that the two taps are rotatably disposed on opposite sides of the main body.

An internal combustion engine may include a housing and at least one cavity arranged therein for receiving a coolant flow. An exhaust gas cooler may be provided for cooling an exhaust gas flow. The exhaust gas cooler may be configured as a stacked disc cooler including at least two stacking discs, an exhaust gas inlet, a cover plate and a screw-mounting plate for screw-mounting to the housing. The exhaust gas cooler may protrude into the cavity of the housing when the screw-mounting plate is mounted to the housing. The screw-mounting plate may have a spacer element disposed at the exhaust gas inlet. The spacer element may protrude in a direction of the at least two stacking discs and enlarge a distance between the screw-mounting plate and an adjacent stacking disc of the at least two stacking discs to position the exhaust gas cooler further into the cavity.

The present invention relates to an apparatus and a method for evaporating liquids containing potentially explosive impurities of lower volatility than the actual liquid compound. The set-up of the evaporator according to the invention allows its operation with complete evaporation of a liquid without formation of a liquid sump of not yet evaporated liquid.

An inline heater includes a heater core that includes a heat spreader assembly comprising a tubular heat spreader that extends axially along a longitudinal axis and that comprises an external surface. The heat spreader assembly includes a fluid inlet and a fluid outlet. At least one conduit extends helically about the longitudinal axis of the heat spreader between the fluid inlet and the fluid outlet to define a fluid heating flow path that fluidically connects the fluid inlet and the fluid outlet. The heat spreader assembly further comprising an electrically operated heating element for heating the heat spreader.

A heat exchanging system includes a frame and at least one heat exchanger. The frame has first and second base members, and first and second sets of crossmembers. The first and second sets of crossmembers extend from the first and second base members, respectively, in opposing directions. The first set of crossmembers engages the second set of crossmembers to form adjoined crossmembers extending between the first and second base members. The crossmembers define at least one window between the first and second base members. The first set of crossmembers is adjustable relative to the second set of crossmembers to increase or decrease a length of each window between the first and second base members. The at least one heat exchanger is disposed within the at least one window.

A cooling device includes: a case that includes a supply port for supplying coolant to an interior of the case and a discharge port for discharging coolant at the interior of the case to an exterior of the case; fins that each have a plate shape, that are arrayed at the interior of the case at separations along a plate thickness direction, and that have coolant flowing between adjacent fins; a maintenance portion that is formed at the fins and that maintains a separation between the adjacent fins; and a restraint portion that is formed at the fins and that restrains relative movement of the adjacent fins being maintained at the separation by the maintenance portion.
