In order to facilitate the installation and maintenance of a heat protection shield in a charging installation of a metallurgical reactor, the cooling assembly (4) comprises a plurality of cooling panels (10), each cooling panel (10) comprising at least one coolant channel (12). The channel (12) is formed as a groove in the base plate (11), which groove is covered by a cover plate (13) mounted on the base plate (11). ## Claims ### Claim 1 A charging installation of a metallurgical reactor, comprising: a cooling assembly disposed for cooling a reactor side of the charging installation, wherein the cooling assembly comprises a plurality of cooling panels, wherein each cooling panel comprises a base plate in which at least one coolant channel is formed, wherein the coolant channel is formed as a groove in the base plate, wherein said groove is covered by a cover plate mounted on and elevated on top of the base plate, wherein the coolant channel has a meandering structure and the cover plate has a meandering structure replicating the shape of the coolant channel, the meandering structure being configured to reduce the risk of a weld disposed between the cover plate and the base plate from breaking whereby the cover plate follows the movement of the coolant channel, and wherein a plurality of eyelets are disposed on an upper side of the base plate, such that the cooling panel is configured to be removable. ### Claim 2 (depends on 1) The charging installation according to claim 1, wherein each cooling panel is mounted by a detachable connection. ### Claim 3 (depends on 1) The charging installation according to claim 1, wherein the base plate is made of metal. ### Claim 4 (depends on 1) The charging installation according to claim 1, wherein each panel comprises at least one coolant pipe which is connected to the coolant channel. ### Claim 5 (depends on 1) The charging installation according to claim 1, wherein coolant channels of different panels are connected in parallel to a coolant supply. ### Claim 6 (depends on 1) The charging installation according to claim 1, wherein at least one heat protection element is mounted to each cooling panel. ### Claim 7 (depends on 6) The charging installation according to claim 6, wherein the heat protection element comprises a plurality of heat protection tiles, said tiles being disposed adjacent to each other along a surface. ### Claim 8 (depends on 7) The charging installation according to claim 7, wherein the heat protection tiles comprise a support structure on which a refractory material, is disposed. ### Claim 9 (depends on 7) The charging installation according to claim 7, wherein a gap is arranged between neighbouring heat protection tiles and wherein the gap is filled with a material which is volatile under the operating temperatures of the metallurgical reactor. ### Claim 10 (depends on 8) The charging installation according to claim 8, wherein the support structure comprises a mesh on which the refractory material is disposed. ### Claim 11 (depends on 1) The charging installation according to claim 1, further comprising a casing for a gear assembly and the cooling assembly configured to protect an annular bottom surface of the casing. ### Claim 12 (depends on 7) The charging installation according to claim 7, wherein the cooling panels are mountable and dismountable from inside a casing for a gear assembly and the cooling assembly configured to protect an annular bottom surface of the casing. ### Claim 13 (depends on 7) The charging installation according to claim 7, wherein a hoist device for handling the panels is disposed inside a casing for a gear assembly and the cooling assembly configured to protect an annular bottom surface of the casing. ### Claim 14 A cooling assembly for a charging installation of a metallurgical reactor, said cooling assembly disposable for cooling a reactor side of the charging installation and comprising: a plurality of cooling panels, each cooling panel comprising a base plate in which at least one coolant channel is formed, wherein the coolant channel is formed as a groove in the base plate, said groove being covered by a cover plate mounted on and elevated on top of the base plate, and wherein the coolant channel has a meandering structure and the cover plate has a meandering structure following the meandering structure of the coolant channel, the meandering structure being configured to reduce the risk of a weld disposed between the cover plate and the base plate from breaking whereby the cover plate follows the movement of the coolant channel, and wherein a plurality of eyelets are disposed on an upper side of the base plate, such that the cooling panel is configured to be removable. ### Claim 15 A cooling panel for a cooling assembly disposable for cooling a reactor side of a charging installation, said cooling panel comprising: a base plate in which at least one coolant channel is formed, wherein the coolant channel is formed as a groove in the base plate, said groove being covered by a cover plate mounted on and elevated on top of the base plate, and wherein the coolant channel has a meandering structure and the cover plate has a meandering structure following the meandering structure of the coolant channel, the meandering structure being configured to reduce the risk of a weld disposed between the cover plate and the base plate from breaking whereby the cover plate follows the movement of the coolant channel, and wherein a plurality of eyelets are disposed on an upper side of the base plate, such that the cooling panel is configured to be removable.
