Accumulator tank

An accumulator tank for handling a heat transfer medium, comprising:

• a tank with a top section and a bottom section;
• a plurality of partition walls located inside the tank and arranged between the bottom section and the top section to divide the tank into a plurality of spaces;
• wherein the accumulator tank is connected to a heat-emitting system and a heat-absorbing system, each of the heat-emitting system and the heat-absorbing system being connected to at least one respective space so that a temperature gradient is created between the bottom section and the top section;
• wherein the partition walls are welded onto the accumulator tank along substantially its entire inner periphery, such that the strength of the accumulator tank is increased and movement of the medium between the spaces of the accumulator tank along its inner walls is prevented;
• wherein the tank has the shape of an upright cylinder with a D-shaped cross-section when viewed from above and is devoid of any external structural support;
• wherein a flat wall of the cross-section has an exposed outer surface;
• wherein a plurality of pipes in a first bundle penetrate through an upper end surface of the tank, extend inside the tank, and each pipe respectively opens into a different one of the spaces;
• wherein a plurality of pipes in a second bundle penetrate through the upper end surface of the tank, extend inside the tank and each pipe respectively opens into a different one of the spaces;
• wherein the plurality of pipes in the first bundle are connected to the heat-emitting system;
• and
• wherein the plurality of pipes in the second bundle are connected to the heat-absorbing system.
