To provide a cooling system capable of easily cleaning between a plurality of heat exchanger cores, capable of maintaining cooling performance, and superior in space efficiency to a swing-out structure.
One heat exchanger core 23 positioned on the front side (the outside surface side) is movably arranged between an approaching position and a separating position, while holding a parallel attitude by four L-shaped cross-sectional guide rails 25, to the other heat exchanger core 21 positioned on the back face side (the engine side). When operating the cooling system 10, cooling efficiency is improved, by increasing the air volume passing through the front side heat exchanger core 23, by approaching a separate distance of the front side heat exchanger core 23 to the back face side heat exchanger core 21. In cleaning, the front side heat exchanger core 23 is slid forward by a guide of a plurality of guide rails 25, and the cleaning is performed by an air jet, by inserting a cleaning fluid jetting nozzle into an expanded clearance, by expanding the clearance between the heat exchanger core 21 and the heat exchanger core 23.
