Abstract: A plate for a heat exchanger for heat exchange between a first and a second medium has a first side and an opposing second side. The first side is configured with at least one heat transferring elevation and with at least one heat transfer surface surrounding the elevation. Dimples are provided at either or both of the heat transferring elevation and the heat transfer surface to permit provision of a through-flow duct for the first medium. The second side is configured with at least one heat transferring depression corresponding to the elevation. The depression is configured to define a part of a through-flow duct for the second medium. The second side has at least one bonding surface corresponding to the heat transfer surface and surrounding the depression. A heat exchanger includes a stack of the above-mentioned plates and an air cooler includes such a heat exchanger.

Abstract: The present invention relates to a plate (1) for a heat exchanger for heat exchange between a first and a second medium. The plate has a first side (A) and an opposing second side (B). The said first side (A) is configured with at least one heat transferring elevation (2) and with at least one heat transfer surface (4) surrounding the elevation. Dimples (5; 7) are provided at either or both of the heat transferring elevation (2) and the heat transfer surface (4) to permit provision of a through-flow duct (X) for the first medium. The second side (B) is configured with at least one heat transferring depression (3) corresponding to the elevation. The depression being configured to define a part of a through-flow duct (Y) for the second medium. The second side (B) is configured with at least one bonding surface (6) corresponding to the heat transfer surface and surrounding the depression.

Abstract: The invention relates to a plate heat exchanger (1) comprising at least one cassette (2a-c) formed by a pair of adjacent plates (3a, b) in a plate stack (10). An inner heat transfer duct (4) runs between adjacent plates (3a, b) within the cassette (2a-c). An insulating duct (6, 12) is disposed adjacent to the inner heat transfer duct (4) along at least one edge portion of the cassette (2a-c). The insulating duct (6, 12) is configured to insulate and separate the inside of the plate heat exchanger's heat transfer ducts (4, 11) from the environment outside the plate heat exchanger (1) in a direction transverse to a main heat transfer direction (7) through the plates (3a, b) of the cassette (2a-c) and thereby reduce temperature losses from the plate heat exchanger (1) to the surrounding environment.

Abstract: The invention relates to a heat exchanger (1) of crossflow type for heat exchange between different media, which heat exchanger (1) comprises a plate stack (2) of heat transfer plates for first and second plate types (3, 4). The plate types (3,4) are stacked 5 alternately on one another in the plate stack (2). Each plate type (3, 4) has a side A and a side B with a heat exchange surface (9). The heat exchange surface (9) comprises a pattern (10a, b). In the plate stack (2), adjacent plate types (3, 4) form both first throughflow ducts (14) and second throughflow ducts (15). Said first throughflow ducts (14) have a larger volume than said second throughflow ducts (15), the volume of a first medium (16) in said 10 first throughflow ducts (14) being greater than the volume of a second medium (17) in said second throughflow ducts (15).

Abstract: Flexible conveyor belt of the type which can be assembled to form an endless loop, a part of which forms a number of layers stacked one on another. The belt (3) is constructed from mutually articulatable links which each comprise at least two transverse rods (13) which, at each side edge of the belt, bear support members (12) projecting upwardly from the plane of the belt, which are intended to support a belt layer lying above. The links are interconnected so that they can be displaced relative to one another along at least one side edge of the belt. The support members (12) are connected to the ends of the transverse rods (13) in the belt (3) or constitute extensions of these rods and comprise a stirrup-shaped support portion which projects upwardly from the plane of the belt and interconnects the rods (13) in an associated link of the belt. The invention also relates to a climate chamber comprising a belt according to the above, and a method for treating products in such a climate chamber.
