Abstract

A heat exchanger has a container with an outer mantle and pipes positioned in the container for conveying a heat-receiving medium through the container. The heat-transferring medium flows exterior to the pipes in counter flow to the heat-receiving medium in the pipes. A common inlet tube is connected to the container and communicates with the pipes for introducing the heat-receiving medium. A common outlet tube is connected to the container and communicates with the pipes for removing the heat-receiving medium from the pipes. The pipes extend meander-shaped within the container. The common inlet tube penetrates the outer mantle on opposite sides and has an inflow end and a remote end. The inflow end is pressure-tightly connected to the outer mantle. The common outlet tube penetrates the outer mantle on opposite sides and has an outflow end and a remote end. The outflow end is pressure-tightly connected to the outer mantle. First and second receiving chambers are pressure-tightly connected to the exterior of the outer mantle. The remote end of the common inlet tube is received in the first receiving chamber and the remote end of the common outlet tube is received in the second receiving chamber.

Dependent claims

A heat exchanger comprising:

a container with an outer mantle;
pipes positioned within said container for conveying a heat-receiving medium through said container, wherein a heat-transferring medium flows exterior to said pipes in counterflow to the heat-receiving medium in said pipes;
a common inlet tube connected to said container and communicating with said pipes for introducing the heat-receiving medium into said pipes;
a common outlet tube connected to said container and communicating with said pipes for removing the heat-receiving medium from said pipes;
said pipes extending meander-shaped within said container;
said common inlet tube having an inflow end and a remote end, said common inlet tube penetrating said outer mantle on opposite sides, wherein said inflow end is connected in a pressure-tight manner to said outer mantle;
said common outlet tube having an outflow end and a remote end, said common outlet tube penetrating said outer mantle on opposite sides, wherein said outflow end is connected in a pressure-tight manner to said outer mantle;
a first receiving chamber and a second receiving chamber connected in a pressure-tight manner to an exterior of said outer mantle;
said remote end of said common inlet tube received in said first receiving chamber;
and
said remote end of said common outlet tube received in said second receiving chamber.
