摘要

A cooling grid of a cooler device capable of suppressing variations in passage pressure loss of cooling air is provided. The cooling grid 1 includes a plurality of support plates 24 and 25 and a plurality of covering members 23. The support plates 24 and 25 are arranged at intervals in the transport direction so that the slits 27 through which the cooling air passes are formed therebetween, and the clinker layer 14 is placed thereon. Further, the support plates 24 and 25 have mounting portions 28 located on both sides of the slit 27 in the transport direction over the entire slit 27, and the covering member 23 is mounted on the mounting portion 28. The covering member 23 is formed in a V-shaped cross section having a tapered portion 23a. The covering member 23 is placed on the placing portion 28 with a plurality of spacers 22 interposed between the tapered portion 23a and the placing portion 28. 27 is entirely covered from above. The plurality of spacers 22 are arranged at intervals in the orthogonal direction.
