A heat exchanger comprising a casing wherein a bank of tubes is arranged and provided with means for conducting a first medium through the tubes of the bank from a supply opening for said medium in the wall of the casing, and means for conducting a second medium from another supply opening in the wall of the casing around the tubes of the bank towards a discharge opening in the wall of the casing, whereby the means for conducting the second medium through the apparatus comprise a pump impeller arranged centrally at the bottom of the casing, said impeller being connected to a pump shaft projecting upwardly within a cylindrical inner jacket disposed centrally in the casing and which is driven above the casing by a motor arranged in situ, while the tube bank for the first medium is an annular bank which is arranged around the cylindrical jacket, whereby the tubes of the bank are tubes of the bayonet type.
A heat exchanger, comprising a casing, a cylindrical inner jacket arranged centrally in said casing, an assembly of tubes of the bayonet type arranged as an annular bank around the cylindrical jacket in said casing, a supply opening for a first medium in the wall of said casing, a discharge opening for said first medium in the wall of said casing, means for conducting the first medium through said tubes from said supply opening to said discharge opening, a supply opening for a second medium in the wall of the casing, a discharge opening for said second medium in the wall of the casing, a pump impeller arranged centrally at the bottom of said casing for conducting said second medium from said supply opening thereof around said tubes to said discharge opening thereof, a pump shaft connected to said impeller and projecting upwardly inside said cylindrical inner jacket, and a motor disposed in situ for driving said pump shaft above said casing.
