摘要

1. The cooler exhaust gas recirculation system (EGR), comprising: a refrigerant channel containing a refrigerant inlet located on the first longitudinal surface of the cooler and fluidly connected to the external circuit of the cooler, and a refrigerant outlet located on the second longitudinal surface of the cooler and connected in fluid medium with an external cooler circuit, the second longitudinal surface being opposite and parallel to the first longitudinal surface, the first exhaust gas channel containing an inlet and an outlet is located on opposite transverse surfaces, the transverse surfaces being perpendicular to the first and second longitudinal surfaces, and a second exhaust gas channel equal in length to the first exhaust gas channel, comprising an inlet and an outlet located on opposite transverse surfaces, wherein the entrance of the second exhaust gas channel is located on the same surface, as the output of the first exhaust gas channel, and the output of the second exhaust gas channel is located on the same surface as the input of the first exhaust channel avshih gazov.2. The EGR cooler according to claim 1, characterized in that it is mounted on the engine, while the inputs and outputs of the exhaust gases of the EGR cooler are perpendicular to the axis of the engine crankshaft. 3. The EGR cooler according to claim 1, characterized in that the first and second exhaust gas channels are combined to form a combined exhaust gas pipe behind the EGR cooler. 4. The EGR cooler according to claim 1, characterized in that the first and second exhaust gas channels are equal in length from the inlets to the combining point at which the first and second exhaust gas channels form
