Abstract: A heat dissipation device includes a base plate and a plurality of fins arranged on the base plate. Each fin includes a fin body including a first metal sheet and a second metal sheet coupled to each other, wherein the fin body is curved and includes a first portion and a second portion transverse to the first portion, an evaporation channel defined in the first portion, one or more connecting channels disposed in the first portion and in fluid communication with the evaporation channel, a condensation channel defined in the second portion, and one or more auxiliary channels disposed in the second portion and in fluid communication with the one or more connecting channels and the condensation channel.

Abstract: A selective access device for a picking/depositing station in warehouse defines an access area engaged by a first cover that is defined by a pair of movable plane surfaces parallel or coplanar to one another; these plane surfaces are slidable along a first rectilinear axis under the action of a movement system so as to open/close a first opening; in the access area, there is provided a second cover above the first cover, to define a second opening aligned with the first opening; the second cover consists of a plurality of doors, each rotating about a relative rotation axis in respect to the first cover; the doors are arranged side-by-side along a second rectilinear axis, orthogonal to the first axis and are closed by respective locks, while the rotation axes are parallel to this second axis.
