Plate For Heat Exchanger And Heat Exchanger Equipped With Such Plates

Abstract

The invention relates to a plate intended to enable an exchange of heat between a first and a second fluid circulating in contact with the plate, said plate being configured to define a circuit for the first fluid. According to the invention, said plate comprises one or a plurality of protuberances intended to penetrate into a plate for collecting the first fluid and defining an inlet into and/or an outlet from the circuit. The invention also relates to an array of such plates and to a heat exchanger comprising such an array.

1 . A plate for exchanging heat between a first and a second fluid circulating in contact with the plate, the plate configured to define a circuit for the first fluid, wherein the plate comprises one or a plurality of protuberances penetrating into a collector plate for the first fluid and defining an inlet into and/or an outlet from the circuit. 
     
     
         2 . The plate as claimed in  claim 1 , comprising two protuberances respectively defining the inlet into and the outlet from the circuit. 
     
     
         3 . The plate as claimed in  claim 1 , comprising two small sides and two large sides, such that the plate possesses the shape of a rectangle, the one or the plurality of protuberances being situated at a level of the small sides of the rectangle. 
     
     
         4 . The plate as claimed in  claim 1 , wherein the plate and the one or the plurality of protuberances comprise a bottom and margins defining the circuit, the bottom of the one or the plurality of protuberances and the bottom of the plate extending in a plane. 
     
     
         5 . The plate as claimed in  claim 4 , in which the margins delimiting the circuit are parallel to one another at the level of the one or the plurality of protuberances and the margins are flared out in a direction of the circuit ( 8 ). 
     
     
         6 . An array for exchanging heat, the array comprising a stack of plates according to  claim 1 , the plates being arranged in pairs such that two plates of the same pair define a circulation channel for the first fluid. 
     
     
         7 . A heat exchanger comprising the array for exchanging heat as claimed in  claim 6  and the collector plate, penetrated by the one or the plurality of protuberances of the plates. 
     
     
         8 . The heat exchanger as claimed in  claim 7 , comprising a housing provided with four walls and having an interior with the array disposed within the interior, and with the collector plate further defined as one of the four walls. 
     
     
         9 . The heat exchanger as claimed in  claim 7 , comprising at least one inlet collector, into an interior of which the one or the plurality of protuberances of the plates defining the inlet into the circuits discharge, and one outlet collector, into an interior of which the one or the plurality of protuberances of the plates defining the outlet from the circuits discharge. 
     
     
         10 . The heat exchanger as claimed in  claim 7 , in which the collector plate comprises a plane section and collars surrounding the one or the plurality of protuberances. 
     
     
         11 . The heat exchanger as claimed in  claim 10 , wherein the one or the plurality of protuberances comprise margins terminating at a flat surface permitting brazing of the one or the plurality of protuberances to one another and the margins extending in a plane parallel to a plane in which the bottom of the one or the plurality of protuberances extends. 
     
     
         12 . The heat exchanger as claimed in  claim 11 , in which two plates forming a pair of plates are in contact at a level of an internal surface of the flat surfaces. 
     
     
         13 . The heat exchanger as claimed in  claim 11 , wherein the collars conform to an external surface of the margins of the one or the plurality of protuberances and an external surface of the bottom of the one or the plurality of protuberances and/or a lateral surface of the flat surfaces is in contact with the plane section of the collector plate. 
     
     
         14 . The heat exchanger as claimed in  claim 7 , comprising baffles disposed therein, the baffles extending between two pairs of plates until the baffles are in proximity to the collector plate. 
     
     
         15 . A module for admission of air comprising an exchanger according to  claim 7 .
