The invention relates to a heat exchanger for transferring heat between two fluids with different temperature, said heat exchanger comprises a first heat exchange element (10, 11), said first heat exchange element (10, 11) having at least one core (20, 21) extending longitudinally through the heat exchange element, said at least one core (20, 21) defining a core cavity, said cavity being configured with an inlet port 22a and an outlet port 22b to receive a first fluid flowing there through, said heat exchange element (10, 11) having ribs (30) extending continuously substantially in parallel with the at least one core (20, 21) along the whole length of said core (20, 21), said ribs (30) extending radially outwardly from the core (20, 21) and being exposed to contact with a second fluid, flowing along said ribs (30). The invention being distinctive in that each said rib (30, 31) is divided into at least two radially extending fins (33, 34, 35, 36) at a radial distance from the core (20, 21), each said fin (33, 34, 35, 36) extends to a proximity of an outer casing surrounding said first heat exchanger element (10, 11) or a proximity of fins (33,34, 35, 36) of an additional heat exchanger element (10, 11), said additional heat exchanger element (10, 11) being arranged adjacent to said first heat exchanger element (10, 11), said inlet port (22a) and said outlet port (22b) being coupled to said core (20, 21) at the same end of the core (20a, 21a)

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 plate heat exchanger gasket is configured to be positioned between adjacent heat transfer plates in a plate heat exchanger and includes a continuous seal part integrated with spaced-apart wedge parts. The media pressure produced by the fluids flowing in the plate interspaces act on the continuous seal part and applies a force tending to push the continuous seal part outwardly. The wedge parts are sized to contact and act against portions of the heat transfer plates so that movement of the wedge parts is prevented. Because the wedge parts are integrated with the continuous seal part, the wedge parts thus prevent the continuous seal part (plate heat exchanger gasket) from being pushed outwardly and so blow-outs are not so likely to occur.

A data plate assembly for installation with a plate heat exchanger. The data plate assembly includes a monitoring device assembled with a spacer plate. The spacer plate includes inlet and/or outlet holes, and a port that extends from an outer edge of the spacer plate to one of the inlet and/or outlet holes. The port retains the monitoring device therein such that the monitoring device extends into the inlet and/or outlet holes to monitor characteristics of the process and cooling fluids flowing through the holes and the plate heat exchanger. As the performance of the plate heat exchanger degrades, the characteristics accumulated over a period of time may provide an indication that the performance of the plate heat exchanger is degrading and/or the rate in which the performance of the plate heat exchanger degrades.

A plate (2) for a plate kind heat exchanger (1) is disclosed. The plate (2) is provided with a plurality of corrugations (8), a cross-section of the plate (2) thereby defining a plurality of hills (9) and valleys (10) which define flow paths along surfaces of the plate (2). The hills (9) and/or the valleys (10) have a shape which is asymmetrical with respect to a center line (11, 12) intersecting a top point of the hill (9) and/or valley (10). A plate kind heat exchanger (1) having a plurality of such plates (2) arranged in a stacked configuration, where the hills (9) and valleys (10) formed in the plates (2) define flow paths between the plates (2) is also disclosed.

A modular system for heat exchange between fluids includes two end plates. At least one end plate is configured with inlets and outlets for fluids. The modular system includes a number of heat exchanger elements and a number of guiding elements. Each heat exchanger element includes a folded sheet material including a plurality of slits extending in a longitudinal direction of the folded sheet material, which longitudinal extending slits form the fluids flow paths. The folded sheet material is cast in one piece in an outer casing. A central opening of the outer casing covers an outer circumference of the folded sheet material, exposing a front side and a back side of the folded sheet material where two through holes, forming the inlets and outlets for each fluid, are provided on opposite sides of the central opening of the outer casing. Each guiding element includes two inlets and two outlets for fluids, and a bead or edge, provided on one side, forming an enclosure around the inlet and outlet for a first fluid, and a bead or edge on an opposite side, forming an enclosure around the inlet and outlet for a second fluid. Heat exchanger elements and guiding elements are arranged successively following each other. The heat exchanger elements are arranged that two adjacent heat exchanger elements on sides facing each other carry the same fluid.

A heat sink (10) comprising a plurality of parallel fins (12) and a plurality of plates (14). Each plate (14) is located between an adjacent pair of fins (12) and one or more securing members is provided to secure the fins (12) and plates (14) in contact. Each of the plates (14) is formed of a material being softer than the material of the fins (12) such that compression of the fins (12) and plates (14) deforms the surface of the plates (14) to improve thermal conductivity between adjacent fins (12).

The present invention relates generally to a heat sink comprising a plurality of fins, each fin having two or more prongs extending from a root section of the fin. In certain embodiments, the heat sink may be assembled by aligning the plurality of fins within slots between protrusions extending from a base of the heat sink. However, in other embodiments, the plurality of fins may have connector ends having female sides and opposite male sides, wherein the plurality of fins may be attached to each other via the interlocking female and male sides, thereby forming at least part of the base of the heat sink, and fortified with reinforcing members.
