Adiabatic pre-cooling system for V-type air cooled heat exchanger

Adiabatic pre-cooling system with V-type air cooled heat exchangers (1), wherein the V-type air cooled heat exchanger (1) comprises two air inlet areas (2) arranged in V-type configuration to each other, an air outlet (3) arranged above two air inlet areas (2) and at least one fan (4) configured to provide an air flow (A) from the air inlet area (2) to the air outlet (3),

• wherein the system comprises:
• an adiabatic panel (5) arranged in front and in parallel to the air inlet area (2) of the V-type air cooled heat exchanger (1) so that the incoming air flow (A) first flows through the adiabatic panel (5) and then through the air inlet area (2) of the V-type air cooled heat exchanger (1) into the V-type air cooled heat exchanger (1);
• a water spraying unit (10) arranged in front of the adiabatic panel (5),
• wherein the water spraying unit (10) comprises a horizontal water spraying sub-unit (11) arranged at a lower edge of the air inlet area (2) and two vertical water spraying sub-units (12) arranged on each end of the horizontal water spraying sub-unit (11) and fluidly connected thereto, wherein the horizontal water spraying sub-unit (11) and two vertical water spraying sub-units (12) are arranged parallel to the adiabatic panel (5);
• each water spraying sub-unit (11;
• 12) comprises a nozzle pipe (20) and at least two nozzles (22) installed on said nozzle pipe (20), wherein the nozzles (22) on the vertical water spraying sub-unit (12) are arranged so that water from the nozzles (22) is sprayed parallel to the adiabatic panel (5) and toward each other, and wherein the nozzles (22) on the horizontal water spraying sub-unit (11) are configured so that the water can be sprayed in the range from a longitudinal direction to a direction of the incoming air flow (A) to a parallel direction to the adiabatic panel (5),
• a water management unit (30) fluidly connected to the water spraying unit (10) and configured to supply the water to the water spraying unit (10).
