Abstract

Abstract A plate type condenser comprising a plurality of heat transmitting plates which are assembled in side-by-side contacted relation and enclosed in a container or shell, with a gasket disposed between adjacent heat transmitting plates in such a manner that suitably opened steam passages and closed cooling liquid passages are alternately defined in the internal clearances of the plate assembly. The plate type condenser is constructed to improve the heat transmitting performance in that the pressure loss of steam at the steam inlet opening in the side-by-side contacted plates is reduced and the gaskets for preventing leakage of cooling liquid are fixed; that short pass between the plates and the shell is prevented to limit the flow of steam to a given direction; and that the influences of uncondensable gases contained in the steam on the heat transmitting performance of the condenser are minimized with due consideration given thereto.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 96 words
A plate type condenser wherein a plurality of heat transmitting plates vertically assembled in side-by-side contacted relation with a gasket disposed between adjacent heat transmitting plates to define therebetween suitably opened steam passages are solely supported by seal stays and enclosed in a shell, wherein said stays divide said shell into an upper and a lower portion and said stays and the gaskets between adjacent plates are contacted and cooperate with each other to provide a steam seal construction between the heat transmitting plates and the shell, thereby sealing said upper portion from said lower portion.
Claim 2
Dependent Claim 96 words
A plate type condenser wherein a plurality of heat transmitting plates vertically assembled in side-by-side contacted relation with a gasket disposed between adjacent heat transmitting plates to define therebetween suitably opened steam passages are solely supported by seal stays and enclosed in a shell, wherein said stays divide said shell into an upper and a lower portion and said stays and the gaskets between adjacent plates are contacted and cooperate with each other to provide a steam seal construction between the heat transmitting plates and the shell, thereby sealing said upper portion from said lower portion.
Claim 3
Dependent Claim 43 words
A plate type condenser as set forth in claim 1, wherein a labyrinth is defined in a space between said gaskets and the seal stays by fins protruding from an outer edge of each of said gaskets, said fins contacting said seal stays.
