The invention relates to a cooling plate (1, 101) for a shaft furnace provided with a refractory lining. Said shaft furnace comprises a first laminated cooling plate element (2, 102) which is oriented towards the inside of the furnace (Oi), a second laminated rear cooling plate element (3, 103) which is welded to the first element, a cooling channel (7, 107) arranged between the first and second cooling plate elements, and tube sections (8, 9) to the cooling agent inlet or the cooling agent outlet. The aim of the invention is to improve the production, flow and cooling properties. To this end, the first cooling plate element (2, 102) is embodied in the form of a bloom having a plane front side (14) facing the inside of the furnace (O1), and the cross-sectional surface of the cooling channel is larger than in the central region (20; 120), in relation to the longitudinal extension of the cross-section in the end regions (18, 19; 118, 119). The invention also relates to a cooling plate system (33).
