摘要:
The present invention relates to an improved heat exchanger and an improved method of heat exchange using a plate-type heatexchanger permitting the exchange of heat between a first fluid in liquid form and a second fluid in gaseous form, joined together and circulating in certain passages of the exchanger, and a third fluid circulating in other adjacent passages of the exchanger. The characteristic improvements of said exchanger include the provision of a third inlet towards the first passage, defined by a first closure means adjacent to a second inlet and to one extremity of the first passage so as to introduce into said first passage the fluid to be received into said second passage; a third distribution means is arranged in the first passage to distribute the fluid to be received in said second passage, from the third inlet towards the interior of said first passage, substantially over the whole dimension of said passage perpendicular to the longitudinal direction, the transfer zone also extending along the longitudinal direction and comprising a plurality of perforations separated from each other. The transfer zone between passages may comprise a plurality of longitudinally elongated slots or a plurality of slots perpendicular to the longitudinal direction or a plurality of orifices distributed in the longitudinal direction of the second plate.
摘要:
Heating elements formed by joining a pair of plates around most of their peripheries are provided with an internal partition which separates upper and lower internal spaces within the element so that separate streams of condensate are discharged from the element. A plurality of such plate elements can be used in a falling film condenser.
摘要:
A vacuum condensor with condensate catch, consisting of a horizontal cylindrical housing with neck, the both bottoms of which are closed by covers, and inside the housing there are mounted heat-exchange bodies, while externally to it there are connected a deaeration device and a condensate pump. The heat-exchange bodies can be either pipes or plates.
摘要:
A refrigerated air or like dryer in which apparatus to perform the several functions of such a dryer are combined in a unit of small, compact size. A heat exchange device is uniquely constructed to perform both the principal cooling and the precool-reheat functions. A housing in an enclosing relation to the heat exchange device induces separation and drainage of liquid from the cooled gas, eliminating the need for external separator means and attendant connections.
