Abstract: In a cooling unit for an absorption circuit, an absorber, a generator, a condenser, and an evaporator are provided. The absorber is built by at least two mutually connected profiled plates which form lines and ports for connecting the generator to the evaporator. The lines are guided in a meander pattern and two adjacent lines are mutually connected through at least one opening. The absorber can be pivoted by an at least partial inclination of the lines with respect to horizon from a neutral position by an axis extending in parallel to the plate plane by more than 3.degree., preferably more than 6.degree., without the operation of the cooling unit being impeded by the rotation of the plates. This permits the cooling unit to be used on mobile vehicles and boats where frequent inclined positions occur.
