Abstract:
Die Erfindung betrifft ein Verfahren zur Herstellung eines Kühlbauteils, mit einem insbesondere länglichen Kühlkörper (11) aus Metall oder aus einer Metalllegierung, mit dem ein Gegenstand gekühlt werden kann, wobei der Kühlkörper (11) ein oder mehrere Mediumkanäle zum Durchfluss von Kühlmedium aufweist, sowie mit einem mit dem Kühlkörper (11) fluiddicht verbundenen Anschlussteil (12), über das dem Kühlkörper (11) das Kühlmedium zuführbar ist und/oder über das von dem Kühlkörper (11) das Kühlmedium abführbar ist.
Abstract:
An end cover 100 of a shell and tube heat exchanger comprises a plastics / plastics composite body 105 and a metal plate member 110 encased in the body providing structural rigidity to the body. The plate may be dome shaped pressed steel having a zinc coating (fig 10). The end cover may comprise a sealing face 107 for bearing against the shell. The shell may have two or more bolt holes (102, fig 5A) for bolting the end cover to the shell. The sealing face may be bowed (107a, fig 9B) between the bolt holes to bias against the shell when the end cover is bolted to the shell. At least one metal (brass) insert 115, 120, (125) may be encased in the body. One insert 115 is internally threaded providing an inlet / outlet (101) of the heat exchanger, one insert 120 may provide a threaded connection for a drain plug (103), and one insert (125) may be a sleeve providing a through hole so that a threaded fastener clamps the end cover to the shell. The sleeve may have a circumferential groove (127, fig 7A) and the plate member a cut-out (112) to interlock with the groove.
Abstract:
A thermal roller (1) includes: a cylindrical body (2) extending along a longitudinal direction (X-X), the cylindrical body (2) including at least one inner tubular element (3) and at least one outer tubular element (4) that is concentrically arranged around the inner tubular element (3), the inner tubular element (3) includes an outer diameter d and the outer tubular element 4 includes an inner diameter D, being D>d; two hubs (6), each arranged at one end of the cylindrical body (2); at least one heat-exchange chamber (10) realized between the inner tubular element (3) and the outer tubular element (4). The roller includes: a coating layer (11) for the inner tubular element (3) made of plastics, and at least one helical channel (13) between the coating layer (11) and the outer tubular element (4). The helical channel (13) is realized at least partially in the coating layer (11).
Abstract:
Condenser assembly, comprising a condenser (110), means for cooling the condenser, and a condenser bag (210, 226, 228) removably coupled with the condenser, the condenser bag bounding a first compartment (242), the condenser bag having a first gas inlet port (248), a first gas exhaust port (250) and a first fluid collection port (244) each communication with the first compartment.
Abstract:
A distributor (1) of coolant in a heat exchanger, which distributor (1) comprises a main body (2) made of plastic material having a plurality of elongated longitudinal seats (21), each one suitable to receive a respective tubular member (3) made of copper wherein, upon use, the coolant flows, at each one of such elongated seats (21) a transversal abutment profile (20) being further obtained, acting as abutment of the main body (2) against the tube plate (104) of the exchanger which arranges, upon use, circumscribed to the respective tubular member (3) made of copper.
Abstract:
Presented herein are articles and methods featuring substrates with thin, uniform polymeric films grafted (e.g., covalently bonded) thereupon. The resulting coating provides significant reductions in thermal resistance, drop shedding size, and degradation rate during dropwise condensation of steam compared to existing coatings. Surfaces that promote dropwise shedding of low-surface tension condensates, such as liquid hydrocarbons, are also demonstrated herein.
Abstract:
An article includes a substrate having a first major surface and optionally a second major surface. A layering arrangement is disposed on either or both of the first major surface and the second major surface. The layering arrangement includes a carbon layer and a conducting polymer layer.
