Claim 0:
1. A refrigeration system, comprising:
a compressor assembly having an inlet of first compression stage, an outlet of first compression stage, an inlet of second compression stage, and an outlet of second compression stage;
a heat rejection heat exchanger assembly, comprising:
a primary heat exchanger having an inlet that is fluidly connected to the outlet of second compression stage of the compressor assembly and an outlet that is fluidly connected to the inlet of a heat absorption heat exchanger assembly, the primary heat exchanger, comprising:
a first tube bank extending between a first manifold and a first intermediate manifold,
a second tube bank extending between a second manifold and a second intermediate manifold,
at least one bend extending between the first tube bank and the second tube bank and fluidly connecting the first tube bank to the second tube bank, and
a connecting tube or a block part extending between the first intermediate manifold and the second intermediate manifold;

a secondary heat exchanger having a third manifold defining an inlet that is fluidly connected to the outlet of first compression stage of the compressor assembly and a fourth manifold defining an outlet that is fluidly connected to the inlet of second compression stage of the compressor assembly; and

the heat absorption heat exchanger assembly fluidly connected to the heat rejection heat exchanger assembly and the compressor assembly;
wherein the primary heat exchanger and the secondary heat exchanger are arranged in a closed shape;
wherein a sealing member connects the third manifold and the second intermediate manifold to seal between the primary heat exchanger and the secondary heat exchanger;
wherein the primary heat exchanger is U-shaped and the secondary heat exchanger extends across a width of the U-shape to define the closed shape.
