A heat transfer plate comprises a first end portion, a second end portion and a center portion arranged in succession along a longitudinal center axis of the plate. The center portion comprises a heat transfer area provided with a heat transfer pattern comprising support ridges and support valleys longitudinally extending parallel to the longitudinal center axis of the plate. The support ridges and support valleys are alternately arranged along a number of separated imaginary longitudinal straight lines extending parallel to the longitudinal center axis of the plate and along a number of separated imaginary transverse straight lines extending perpendicular to the longitudinal center axis of the plate. The heat transfer pattern further comprises turbulence ridges and turbulence valleys. At least a plurality of the turbulence ridges and turbulence valleys along at least a center portion of their longitudinal extension extend inclined relative to the transverse imaginary straight lines.

Methods and devices heat or cool viscous materials, such as meat emulsions useful for producing food and other products. The devices have a heat exchanger including a first plate, a second plate attached to the first plate, and a first spacer and a second spacer arranged between the first plate and the second plate. The first plate, the second plate, the first spacer, and the second spacer define at least one temperature controlled passage for a product to pass through the heat exchanger.

Plate (110) for a heat exchanger (100) between a first medium and a second medium, the plate comprising a first heat transfer surface (114) on a first side (113) of the plate, arranged to be in contact with the first medium; a second heat transfer surface (116) on a second side (115) of the plate, arranged to be in contact with the second medium; a plurality of indentations (120, 130, 140) in the plate (110; 210; 310), bulging out locally in a plate height direction (H), which plate is arranged to be stacked together with similar plates to form a heat exchanger heat plate stack. The invention is characterised in that the plate comprises a ridge-shaped indentation, arranged to form, together with a corresponding ridge-shaped indentation of an adjacent plate in said stack, a closed flow channel (105′, 105″) for the first medium with a general flow direction, in that the said closed channel comprises a floor (105a) and a ceiling (105b), as viewed in the height direction, and comprises a step (105c) in the height direction along said general flow direction by the said floor and said ceiling both being offset in same height direction.

The present disclosure relates to heat exchanger for a power generation system and related methods that use supercritical fluids, and in particular to a heat exchanger configured to minimize axial forces during operation.

A flow-path structure through which fluid flows includes: a barrel body through which fluid flows in an inner circumference; and a frame body configured to connect a flow path member, the flow path member being configured to guide the fluid into the barrel body, wherein the frame body has: a ring-shaped frame part configured to be fitted into an outer surface of the barrel body; and an inner engagement portion configured to engage with an inner surface of the barrel body so as to hold a state in which the outer surface of the barrel body is brought into contact with the frame part.

A block style heat exchanger for a heat pipe reactor having a plurality of heat pipes extending from a reactor core. The heat exchanger includes a plurality of primary channels, each for receiving heat transferred from the core via one of the heat pipes. The primary channels extending within a block of one or more materials. The heat exchanger also includes a plurality of secondary channels defined within the block for transmitting a flow of the secondary heat transfer medium through the heat exchanger from an inlet to an outlet. The block is formed from one or both of: a plurality of plates bonded together, with each plate defining at least a portion of one or more of the plurality of primary channels and/or the plurality of secondary channels, and/or a unitary piece of material formed from an additive manufacturing process.

A heat exchanger includes a first flow path through which a first fluid flows, a second flow path through which a second fluid flows, and an adjustment layer disposed between the first flow path and the second flow path adjacent to each other and that adjusts an amount of heat exchange between the first flow path and the second flow path. The adjustment layer includes a first portion and a second portion having a heat transfer performance lower than that of the first portion, and has a heat transfer performance varied depending on a position in the adjustment layer.

One aspect of this disclosure provides a heating chamber for a gas furnace that comprises opposing halves joined together. The joined opposing halves form a clamshell panel having at least one truncated corner located adjacent a curve located at a back end of a chamber path of the one or more clamshell heating chambers.

A heat exchanger (4) has fluid flow channels (6) with at least one heat exchanging surface (10) which has an undulating surface section for which the surface profile varies along a predetermined direction such that at a first edge (E1) the surface profile follows a first transverse wave (20), at a second edge (E)2 the surface profile follows a second transverse wave (22) and at an intermediate point I between the edges the surface profile follows a third transverse wave (24). The third transverse wave (24) has a different phase, frequency or amplitude to the first and second transverse waves so that chevron-shaped ridges and valleys are formed. This improves the mixing of fluid passing through the channel and hence the heat exchange efficiency.
