Description
Technical Field
The utility model relates to a marine ventilation field, concretely relates to efflux induced air device.
Background
Jet induced draft is a method for ejecting high-speed airflow by using a jet fan or a jet nozzle to drive and induce surrounding air to move along a specific direction so as to achieve the purpose of ventilation. Particularly, in the engine room of the ship, because specific mechanical equipment has large heat productivity, the traditional ventilation cooling can not achieve the purpose of rapid cooling, and cold air is required to be sprayed by jet flow for continuous fixed-point cooling. The existing jet device usually needs an air pipe to be connected with a refrigerating device, and the air pipe is difficult to arrange in a cabin and other specific spaces. Meanwhile, a fan of the jet device is usually driven by a motor and a belt pulley, and when the belt pulley is loosened, the device is required to be disassembled to adjust the belt pulley or replace the belt, so that the field operation is inconvenient.
