Provided is an apparatus for blocking air stream flowing into coke oven chamber from the outside, thereby preventing temperature drop of bricks of the wall body of the coke oven chamber to prevent damage of coke oven and more stably control coke oven and coke quality. An apparatus(1) for blocking air stream flowing into coke oven chamber from the outside when opening chamber of coke oven(200) comprises: an air ejection nozzle part(10) comprising a plurality of air ejection nozzles(14) respectively disposed at the upper side of a gateway of the coke oven such that the air ejection nozzles eject air downward, and a pneumatic pressure tank(26) and an air compressor(24) for supplying air into the air ejection nozzles; a heat sink part comprising heat sink rotary shafts disposed at both sides of the gateway of the coke oven, plate members(36) wound around the rotary shafts such that the plate members can be folded and unfolded, and motors(32) for rotating the heat sink rotary shafts to move the plate members to the gateway of the coke oven and form air flow paths inside the plate members such that air is ejected from both sides of the coke oven gateway; and a collection part(100) comprising a plurality of collection hoods(102) respectively disposed at the lower side of the coke oven gateway, and a dust collector(122) and a discharge fan(120) installed at the output side of the collection hoods to collect and remove air, dust, gas and etc. of the coke oven gateway side.
