Abstract

The sink comprises an aluminium tube (1) with cooling flanges (6,7,8,13) on the outside and/or inside of the tube walls (2,3,4,5,9,10). At least one cavity (11,12) present inside a tube wall is used to house at least one element to be cooled and is in a heat conducting relationship with the tube wall.
