A heat exchanger including a tube/rib block made up of tubes and ribs, the tubes forming fluid channels for conducting a first fluid, in particular a refrigerant, and the ribs arranged between the tubes forming a second fluid channel for conducting a second fluid, such as, in particular, air, which flows around the tubes, a collector being arranged at at least one end of the tube/rib block, which communicates with the fluid channels of the tubes, the at least one collector being provided with a plate-type design and including at least one base plate and a cover plate, which are stacked and soldered in a sealed manner, a spacer for spacing the base plate at a distance from the cover plate and for distributing the first fluid in the collector being provided.

A heat and humidity exchanger comprises panels made up of membrane sheets attached on either side of a separator. Channels extend across each panel between the separator and the membrane sheets. The panels are much stiffer than the membrane sheets. Panels are stacked in a spaced apart relationship to provide an ERV core. Spacing between adjacent panels may be smaller than a thickness of the panels.

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.

A heat exchanger includes partition members, alternately stacked spacing members, and seals. The spacing members include first and second spacing members forming the first and second passages. The first and second spacing members each have a frame portion along a periphery of the partition members. The frame portion of the first and second spacing members have first and second communication sections having first and second communication openings allowing the first and second passages to communicate with outside of the frame portion, and first and second partition walls separating the first and second passages from the outside of the frame portion. The frame portions of the first and second spacing members further have first and second notches provided in portions of the first and second partition walls, and open on an outer side surface of the first and second partition walls. The seals cover surfaces of the first and second notches.

A three-dimensional heat transfer device includes a first thermally conductive casing, a second thermally conductive casing, a first capillary structure, a second capillary structure and a heat pipe. The second thermally conductive casing has a through hole. The second thermally conductive casing is mounted on the first thermally conductive casing so as to form a liquid-tight chamber. The first capillary structure is disposed on the first thermally conductive casing. The second capillary structure is disposed on the first thermally conductive casing. Projections of the first capillary structure and the second capillary structure on the outer surface and an extension surface of the outer surface are located in an extent of the outer surface, and the second capillary structure is located closer to the second thermally conductive casing than the second capillary structure. The heat pipe is disposed through the through hole and in contact with the second capillary structure.

An additively manufactured heat exchanger configured to transfer heat between a first fluid and a second fluid includes a first channel with a first wall configured to port flow of a first fluid and a second channel with a second wall configured to port flow of a second fluid. The heat exchanger also includes a barrier channel containing unprocessed build powder provided by the additive manufacturing process and is located between the first wall and the second wall. The barrier channel is configured to prevent mixing of the first fluid and the second fluid when one of the first wall and the second wall ruptures.

A heat exchanger including a corrugated heat transfer sheet having a first surface and a second surface on opposite sides thereof, a first flow channel for a first fluid flow in a first flow direction parallel to a longitudinal direction, and a second flow channel for a second fluid flow in a second flow direction parallel to the longitudinal direction, the second flow direction being opposite to the first flow direction. The heat exchanger includes a channel dividing system which provides the first flow channel and the second flow channel on opposite sides of the corrugated heat transfer sheet such that the first fluid flow is adapted to be in contact with the first surface, and the second fluid flow is adapted to be in contact with the second surface.

A method for forming a heat exchanger plate includes: securing a wave form metallic sheet to a heat exchanger plate substrate, the substrate comprising a first face and a second face opposite the first face, the securing of the wave form metallic sheet being to the first face; and removing peaks of the sheet.

A cooling device includes a cooler disposed inside a shell main body formed in a cylindrical shape, and having a first surface facing an inlet nozzle and an outlet nozzle, and a partition member fixed to the first surface, and partitioning a portion between the cooler and an inner peripheral surface of the shell main body into a first space communicating with the inlet nozzle and a second space communicating with the outlet nozzle. The partition member includes a main partition plate disposed between the inlet nozzle and the outlet nozzle in an axial direction, a first guide portion extending from an end portion of the main partition plate toward a first end surface of the shell main body, and a second guide portion extending from an end portion of the main partition plate toward a second end surface of the shell main body.
