A drying device for processing a gas to be dried, in particular air, comprises an air/air exchanger which includes an inlet for the gas to be dried and an outlet for the dried gas, an evaporator which receives the gas to be dried from the air/air exchanger, the evaporator being formed by means of a plurality of adjacent layers. The layers comprise at least a first layer configured for the passage of a refrigerating fluid, at least a second layer configured to receive the gas to be dried from the air/air exchanger and a plurality of third layers configured to receive a phase change material. The layers are arranged in a sequence which comprises in alternation a first layer, a third layer, a second layer and a further third layer.

The invention relates to a heat exchanger that is configured to permit an exchange of heat between a first fluid and a second fluid that circulate in passage paths formed by plates (14a, 14b) and fins (16a, 16b) of the heat exchanger, the fluids flowing in a multitude of passage channels (10) each consisting of a closed space (12) delimited by two adjacent plates and two adjacent fins, characterized in that each plate extends along a non-planar surface following at least a first oscillating curve, and each fin further following at least one second oscillating curve along at least one second main direction, in such a way that each passage path allows the fluid to flow in the closed space along a fluid direction defined by a generatrix that is a combination at least of the first oscillating curve and the second oscillating curve.

A heat sink includes: a base plate; and at least one fin secured to the base plate; wherein the base plate has at least one through hole that extends in a first direction parallel to a surface of the base plate, wherein the at least one fin has a projection inserted into the at least one through hole, and wherein, in a second direction that is parallel to the surface of the base plate and that is perpendicular to the first direction, both end surfaces of the projection are in contact with inner wall surfaces of the at least one through hole entirely in a third direction parallel to a thickness direction of the base plate.

A shape-morphing fin includes a fixed portion, a multistable portion, a coupling portion, and a vibration source. The multistable portion functions as a negative stiffness element. The multistable portion is selectively movable between a first position and a second position. The movement between first position and the second position is configured to remove the ice formation from the structure. The coupling portion couples the fixed portion to the multistable portion. The vibration source is configured to produce a resonant vibration to engage the movement of the multistable portion from the first position to the second position.

A plate heat exchanger includes heat transfer plates each of which has openings at four corners thereof, and which are stacked together. The heat transfer plates are partially brazed together such that a first flow passage through which first fluid flows and a second flow passage through which second fluid flows are alternately arranged, with an associated heat transfer plate interposed between the first and second flow passages. The openings at each of the four corners communicate with each other, thereby forming a first header and a second header, the first header allowing the first fluid to flow into and flow out of the first flow passage, the second header allowing the second fluid to flow into and flow out of the second flow passage.

A heat dissipator includes a plate-shaped base portion that extends in a first direction along a direction where a refrigerant flows and in a second direction orthogonal to the first direction and has a thickness in a third direction, and fins that protrude from the base portion to one side in the third direction, extend in the first direction, are arranged in the second direction, and guide the refrigerant. A second of the fins is provided continuously on one side in the first direction that is a downstream side of a first of the fins, and a third fin that is provided continuously on another side in the first direction of the first fin, and includes an end on the one side in the third direction on the other side in the third direction.

The invention relates to a device (2) for transferring heat from a thermally conductive plate (3) capable of capturing the heat from a zone placed on a first side (32) of the plate, the device comprising at least one fin (35) placed on a second side (34) of the plate (30) opposite the first side (32) and having a duct (36) extending in a longitudinal direction (L) between a first end (38) connected to the plate and a second end (4) opposite the first end and which opens out, the duct (36) being connected to at least one Venturi-effect neck (42) bringing cooling air into the duct, the neck (42) being formed in the vicinity of the first end of the duct and the plate (30).
