Double-combination installation method for marine low-speed diesel engine air cooler

According to the double-combination installation method for the air coolers of the marine low-speed diesel engine, the marine low-speed diesel engine comprises two air coolers, an auxiliary fan, a cooling water pipeline and a discharge pipeline, and each air cooler comprises an air cooler core, an air reversing box and a dripping water separator; the double-combination installation method adopts a combination installation mode that double air coolers are adjacently and oppositely arranged, the middle sides of the two air coolers are directly attached to each other, the outer sides of the two air coolers serve as installation operation space, and two air reversing boxes are symmetrically installed in a manner that outer covers are connected. The two air cooler cores and the drip separator are symmetrically installed in the two air reversing boxes respectively, and the two air cooler cores are installed in or drawn out of the air reversing boxes from the two sides respectively. The problem that a plurality of a
