摘要:
A plurality of identical heat exchange plates have respective heat exchange surfaces provided with protuberances acting as turbulence-effecting and spacing means between adjacent plates, such plates being adapted for assembly with marginal gaskets to form plate interspaces for throughflow of two heat exchange media along said surfaces at opposite sides (faces), respectively, of each plate. The plate interspaces are of the same depth, and at least one plate is turned 180* relative to the other plates around an axis extending in the plane of the turned plate, the protuberances of each plate being arranged unsymmetrically and so disposed that two different kinds of plate interspaces are formed by such turning of said one plate, thereby creating different flow conditions for the heat exchange media.

The invention involves a cooling tower with tower column having a hollow, rotatably mounted turret thereon, from the substantial periphery of which a plurality of equally, angularly spaced apart hollow vanes are suspended. Exhaust steam entered into the column passes upwardly and outwardly in the turret to pass downwardly through the vanes into an annular, rotatably mounted receiver. The receiver discharges the cooled fluid into a fixed reservoir, preferably an annular tank. Air around the column rises and passes outwardly through the vanes in heat exchange relationship therewith. The vanes, at least in their upper portions, are so constructed and directed, that the passage of air therethrough tends to impart rotation to the assembly of turret, vanes, and receiver.

A flexible air duct is connected to a dishwashing unit for conducting hot moist air therefrom. Opposite ends of the duct communicate with the dishwashing unit for conducting condensed water back thereto, while hot air is discharged through an air outlet disposed intermediate the ends of the duct. The duct is of oblong cross-section and includes cooling fins on one side.

A heat exchanger for heat exchange between low-temperature and high-pressure air and high-temperature and low-pressure gas comprising a housing, a plurality of partition members disposed substantially radially in the housing for defining therebetween alternate air and gas passages for passing the air and gas in directions opposite to each other, a first corrugated fin disposed in each air passage, and a second corrugated fin disposed in each gas passage. The first fins are suitably cut out at one end thereof to communicate with an air inlet of the heat exchanger, and the second fins are suitably cut out at the end remote from the cut-out end of the first fins to communicate with a gas inlet of the heat exchanger so as to attain satisfactory heat exchange between the two fluids.

A vapor collection system that can be used at an extra-terrestrial body is envisioned to collect target gaseous atoms and molecules that are floating around in a shielded environment at a pressure at or less than 1×10−5 bar. The shielded environment is defined within sidewalls and in some cases is defined within a cover. A condensation surface in the shielded environment is maintained at a temperature between 2° Kelvin and 100° Kelvin to collect the target gas that is floating around, which condenses on the condensation surface as a liquid. A collection receptacle at the condensation surface collects the liquid. A heating element in the shielded environment is made to heat and release the target gas from minerals at or beyond the rim. The gas floats around in the shielded environment.

In a temperature control method of a photosensitive material drying device relating to the present invention, a photosensitive material is heated and dried by drying air heated by a heating device. A temperature of a member heated by the drying air is detected, and operation of the heating device is controlled so that the temperature of the member is maintained within a predetermined range. Further, a photosensitive material drying device relating to the present invention includes a heating device supplying heated drying air to an interior of a drying chamber and heating and drying a photosensitive material for which processing by processing solutions has been completed; an exhaust grill through which exhaust air, which is discharged from a vicinity of a conveying path of the photosensitive material to an exterior of the drying chamber, passes; a temperature sensor, disposed at the exhaust grill in a state in which the temperature sensor is shielded from the drying air and detecting a temperature of the exhaust grill heated by the exhaust air; and a temperature control device which controls the heating device in accordance with a temperature detected by the temperature sensor.

A DEVICE FOR ENABLING A LIQUID TO BE DISCHARGED FROM A ROTATING CHAMBER THROUGH AN END OPENING FORMED IN A CASING PORTION THEREOF AND FOR PREVENTING A GASEOUS FLUID FROM FLOWING THROUGH SAID OPENING IN EITHER DIRECTION, WHICH COMPRISES THE OUTER SEMITORIC HALF OF A TORIC CHANNEL WITH ONE OPENING OF THE CHANNEL DIRECTLY AND SEALINGLY CONNECTED TO SAID CASING END OPENING AND WITH THE CONVEX SURFACE OF THE CHANNEL IN A POSITION RADIALLY MORE REMOTE FROM THE ROTATIONAL AXIS OF THE CHAMBER THAN SAID OPENING, A DISC TRANSVERSE TO THE AXIS EXTENDS RADIALLY INTO THE CHAN-
NEL SO THAT, UPON LIQUID BEING DISCHARGED FROM SAID CASING END OPENING, SAID LIQUID FIRST FILLS SAID CHANNEL TO FORM A LIQUID PLUG BEFORE ISSUING AT THE OTHER END OF THE CHANNEL. IN A PREFERRED EMBODIMENT THE CASING END OPENING AND THE CHANNEL EXTEND, WIDTHWISE, CIRCUMFERENTIALLY AROUND THE ENTIRE CHAMBER.

A blade heat exchanger includes blades that extend axially with respect to an axis of rotation and are elongated in the radial direction. The blades are arranged about the axis such that, when they are disposed in a housing, they form composite condensation and evaporation chambers that are isolated from each other. The interiors of at least some of the blades form the composite condensation chamber. The exteriors of the blades and the inner surface of the housing cooperate to form the composite evaporation chamber.

An heat exchanger apparatus mounted in a closed volume, such as a vehicle overflow tank or vehicle radiator, includes a rotating member divided internally by a stationary disk, with the interior of the rotating member and the disk connected in fluid flow communication with a refrigerant to enable the rotating member to act as a heat sink to sweep condensate back into the surrounding closed volume tank or radiator. The rotating member is rotated at a constant speed to provide a specified heat exchange capacity to enable the engine to operate for extended periods without use of the main heat exchanger or radiator.
摘要:
A closed cycle steam generating system comprising a steam boiler and a steam turbine includes a vacuum pump of the liquid vortex type for condensing the exhaust steam from the turbine, a feedwater pump being employed for returning the condensate to the boiler. The tank of the vortex pump is maintained filled with water and the pressure in the tank is regulated automatically to maintain a predetermined value thereof.
