Evaporator

Abstract

An evaporator with a heat transfer core having a number of pipes and fins, wherein a first fluid can flow through the pipes and a second fluid can flow around the pipes and the fins for heat transfer between the first fluid and the second fluid, with at least one collecting tank which is in fluid connection with the pipes, wherein at least two collecting chambers are formed by means of the at least one collecting tank, wherein one of the collecting chambers is equipped with a first fluid connection pipe which serves as an injection line for supplying the first fluid and the other collecting chamber is equipped with a second fluid connection pipe which serves as a suction line for discharging the first fluid, wherein for mounting an expansion valve on at least one of the fluid connection pipes a retaining element is fastened to at least one of the fluid connection pipes.

What is claimed is: 
     
         1 . An evaporator with a heat transfer core comprising:
 a plurality of pipes and fins, wherein a first fluid is adapted to flow through the pipes and a second fluid is adapted to flow around the pipes and the fins for the heat transfer between the first fluid and the second fluid;   at least one collecting tank that is in fluid connection with the pipes;   at least two collecting chambers formed by the at least one collecting tank, wherein one of the collecting chambers is equipped with a first fluid connection pipe which serves as an injection line for supplying the first fluid and the other collecting chamber is equipped with a second fluid connection pipe which serves as suction line for discharging the first fluid; and   a retaining element fixed to at least one of the connection pipes for mounting an expansion valve on at least one of the fluid connection pipes.   
     
     
         2 . The evaporator according to  claim 1 , wherein for mounting an expansion valve to the two fluid connection pipes, the retaining element being fixed to the two fluid connection pipes. 
     
     
         3 . The evaporator according to  claim 1 , wherein the retaining element is positively fixed to the two fluid connection pipes and is frictionally fixed to at least one of the fluid connection pipes. 
     
     
         4 . The evaporator according to  claim 1 , wherein the retaining element is frictionally connected on one of the fluid connection pipes by an elastic element. 
     
     
         5 . The evaporator according to  claim 1 , wherein the elastic element is arranged as an open or closed ring element and is compressed between the retaining element and a projection of the one fluid connection pipe. 
     
     
         6 . The evaporator according to  claim 5 , wherein the fluid connection pipe has two projections, wherein the retaining element is arrangeable between the two projections in such a way that it bears against one of the two projections and such that the elastic element is compressed between the retaining element and the other projection so that it bears against the retaining element and the other projection. 
     
     
         7 . The evaporator according to  claim 4 , wherein the elastic element has a flat design, which can be placed at least partially around the fluid connection pipe. 
     
     
         8 . The evaporator according to  claim 7 , wherein the elastic element has a flat body and protruding elements, which protrude from the flat body. 
     
     
         9 . The evaporator according to  claim 8 , wherein the protruding elements are formed as point-like and/or line-like elements. 
     
     
         10 . The evaporator according to  claim 9 , wherein the line-like elements are formed as straight or bent line elements, specifically as straight line elements, sinusoidal line elements, serpentine line elements, etc. 
     
     
         11 . The evaporator according to  claim 1 , wherein the retaining element comprises two open receptacles, wherein one receptacle receives the one fluid connection pipe and the other receptacle receives the other fluid connection pipe. 
     
     
         12 . The evaporator according to  claim 1 , wherein the elastic element, which is arranged adjacent to one of the projections, is arranged adjacent to one of the receptacles. 
     
     
         13 . The evaporator according to  claim 1 , wherein the elastic element, which is at least partially placed around the fluid connection pipe, is adapted to be received by the retaining element in the receptacle and is adapted to be accessed by the retaining element.
