Each of these tube ends has a cylindrical end portion 60 which is of substantially lesser diameter than the diameter of the central portion 62 of the tube. This prevents the fluid from flowing through the central passageway in each tube 40 so that the flow is only in the annular passageway occupied by the fin structure 42. 2. 2 Sheets-Sheet 2 E; I I OR 51 William JDonovan ATTORN 5 4. In refrigeration circuits, during cooling heat exchangers are used as evaporator, to absorb energy from the refrigerant. Another object is to provide a unit for passing liquid refrigerant in heat interchange relationship with gas refrigerant without the difliculties which have been encountered with prior equpment for accomplishing the same purposes.

A further object is to provide improved heat-interchange apparatus. The substantial fin surfaces along which the gas flows, and the creation of thin even streams of gas flowing at a rapid rate, insures good heat conductivity between the gas and the fin structures. 310,820, filed September 22, 1952, where there is a further disclosure. http://help.opera.com/Windows/11.50/es-ES/cookies.html A further object is to provide for the above with a structure which is light in weight and sturdy, and which is efficient in operation. increasing, decreasing by affecting the pattern of flow of the heat-exchange media

(Cl. Spain of the central tube 40, and the fluid then forms into a cylindrical stream and passes into header 32' from which it is discharged through outlet connection 20. A wide variety of heat exchanger in refrigeration system options are available to you, such as condition, type, and certification. On the other hand, This entire tube and end plate assembly is placed into the central cylindrical portion 78 of shell 22 and end bells 80 and 82 are welded in place as shown. Leganés 28918.

with fins, with projections, with recessesTubular elements and assemblies thereof with means for increasing heat-transfer area, e.g. C/ Del Agua, 14. It has been indicated above that the fin structures are in good heat-conductive relationship with their tubes 36 and the liquid on the outer surface of the tubes picks up the heat in an efficient manner. You can configure cookies or reject them by clicking on settings and rejection. The fin assembly is shown best in Figure 3 and 4 and comprises a fin structure 42 wound around a central tube 40. 18, 1947 2,445,471 Buckholdt July 20, 1948 2,658,358 Boling Nov. 10, 1953 MECHANICAL ENGINEERING; LIGHTING; HEATING; WEAPONS; BLASTINGDETAILS OF HEAT-EXCHANGE AND HEAT-TRANSFER APPARATUS, OF GENERAL APPLICATIONTubular elements and assemblies thereof with means for increasing heat-transfer area, e.g. Madrid. it has been indicated above that the liquid refrigerant enters the tube shell 22' through the liquid inlet connection 12 and it flows from the shell at the bottom through the liquid outlet connection 14. At the left-hand end of the fin assembly the fluid flows a somewhat annular passageway at the end F urther-- However, at the ends The cylindrical confining wall of shell 22 and the, tapered portions of the tubes 64 insure against pockets, eddy cur rents and cavitation, and there is a smooth even flow with minimum resistance and flash gas does not appear. Heat exchangers are essential elements in refrigeration systems. In systems involving heat transfer, a condenser is a device or unit used to condense a gaseous substance into a liquid state through cooling. concentricallyHeat-exchange apparatus having stationary tubular conduit assemblies for both heat-exchange media, the media being in contact with different sides of a conduit wall the conduits being arranged one within the other, e.g. These cookies are used to analyze the traffic and behavior of customers on the site, help us understand and understand how you interact with the site in order to improve performance.
