Abstract: A micro-channel type evaporator suitable for cooling electronic components is provided having a plate-like body having an external coupling surface with the electronic component to be cooled. The plate-like body internally carries an inlet manifold for a two-phase cooling fluid and an outlet manifold for the fluid downstream of the heat exchange. The inlet and outlet manifolds are in fluid communication by means of a heat exchange chamber placed inside the plate-like body at the coupling surface and by means of unidirectional circulation means of the two-phase cooling fluid. The unidirectional circulation means (T) is housed in the plate-like body and is configured to allow circulation of the liquid phase of the fluid exclusively from the outlet manifold towards the inlet manifold.

Abstract: A heat exchanger is disclosed having a tube bundle, intended to internally receive a first fluid, and a shell with an inlet opening at a first end. The shell allows an internal circulation of a second fluid and is arranged to surround the tube bundle. An inner casing to the shell circumscribes the bundle within a heat exchange chamber so that between the casing and the shell an annular region extending in a continuous way along the length of the bundle is defined. The annular region is in fluid communication with the exchange chamber through an outflow opening obtained at a second end of the inner casing where the latter has a rear wall facing an opening of the shell to outlet the second fluid from the heat exchanger. The inlet and outlet openings are in fluid communication by means of the annular region.

Abstract: A thermal exchange device with reduced sizes and suitable to cool down electronic components in data center is disclosed. The device includes: a pair of outer plates integral thereto, equipped with respective inlet doors and outlet doors for a cooling fluid and for a fluid to be cooled down, respectively; and an intermediate plate, interposed between the outer plates and integral thereto, which intermediate plate bears respective thermal exchange surfaces faced to the outer plates and equipped with fins suitable to increase the area of thermal exchange with the fluids, wherein the whole configuration is so that between each outer plate and the respective exchange surface a passage compartment for the respective fluid remain defined, which thermal exchange device is made integral, at an outer plate, with the casing of the electronic component to be cooled down.

Abstract: A device for locking a filter in a conduit for use in heat exchangers is described. The device includes: a main body apt to be associated with the filter and made in two parts, and three locking arms, which branch off from the main body and have each a first longitudinal end which can be tightened within the main body and a second longitudinal end which abuts on the conduit to block the filter. The locking arms are movable with respect to the main body so as to assume a first configuration of minimal encumbrance, in which the insertion of the device in the conduit is allowed, and a second locking configuration, in which the second longitudinal ends are abutted on the walls of the duct. The device allows a removable locking of the filter in the conduit.

Abstract: A heat exchanger of flooded type, having: a primary tube bundle, inside which a first “hot” operating fluid to be cooled down flows; a skirt, circumscribed to the primary tube bundle, which receives a second “cold” operation fluid which laps against the primary tube bundle in order to subtract heat to the first operating fluid, which second operating fluid flows inside the skirt along to a vertical longitudinal direction orthogonal to the development of the tubes of the primary tube bundle, and wherein the skirt has a prevalent development dimension (L) along the flow longitudinal direction of the second operating fluid; and nozzles for delivering the secondary operating fluid inside the skirt, wherein an alternative configuration is provided using only the second operating fluid flooding the skirt by entering from a side inlet, without the presence of the above-mentioned nozzles, and an additional configuration using only the nozzles but not such side inlet.
