The invention discloses a down-blowing type refrigerating unit for engineering machinery. The down-blowing type refrigerating unit comprises a device shell, wherein a fan chamber is arranged at an upper end of an inner cavity of the device shell, double-impeller centrifugal fans are fixedly connected with the left side and the right side of an inner cavity of the fan chamber, air inlets are formedin a left end and a right end of the fan chamber, air outlets are formed in left and right sides of a lower end of the inner cavity of the fan chamber, a warm air core body is fixedly connected withthe middle of an inner cavity of the device shell through a connecting frame, round holes are formed in the middles of the left side and the right side of the warm air core body, an air inducing plateis fixedly connected with the middle of a lower end of each round hole of the warm air core body, and an evaporator core body is fixedly connected with a lower portion of the inner cavity of the device shell through a connecting support. The down-blowing type refrigeration unit for the engineering machinery is advantaged in that by arranging the choke water drainage mechanism, a large amount of cold air is prevented from overflowing from the water drainage pipe, through the structure provided with the air inducing plate and the round holes, the air can be uniformly blown to the evaporator core body.
