The utility model discloses a precision conditioner hood allowing direct air supply towards equipment. The precision conditioner hood comprising a rectangular box is characterized in that an upper horizontal arc plate is fixedly connected to the front upper edge of the rectangular box, a lower horizontal arc plate is fixedly connected to the front lower edge of the rectangular box, vertical grid bars which are arranged at equal intervals in an arc form are arranged between the front edge of the upper horizontal arc plate and the front edge of the lower horizontal arc plate, the middle, left end and right end of the upper horizontal arc plate are all provided with arc air baffle insertion holes, and an arc air baffle is inserted into each arc air baffle insertion hole. The precision conditioner hood allowing direct air supply towards equipment is simple in structure and low in manufacturing cost; the vertical grid bars in arc arraignment are added, air supply from two sides is increased, cold air is directly supplied to devices installed on two sides of a corridor, the cold air blown by an air conditioner enters the devices to be cooled, at a shortest distance, energy consumption of the air conditioner is reduced effectively, and economic benefit is increased for enterprises.
