Disadvantages of a refrigerator are complex design of the cooling system, poor repair of the U-shaped ribs with plugged ends, quick destruction, the low efficiency of heat removal due to the small contact surface of the cooling water with the surface of the cooling body.

Closest to the claimed object to the technical essence is a rotating refrigerator, including mounted horizontally cylindrical hollow heat exchange casing provided with inlet and discharge openings, with hollow heat exchanger casing is placed inside uznogo housing, rigidly fixed with a heat exchange enclosure, with space for circulation of cooling water, and in the Central part of the heat exchanger hollow body of the refrigerator is installed pipe to drain cooling water, coupled with the hollow space between the heat exchanger and the outer shells of the refrigerator in the download area of the refrigerator coke to discharge it from the discharge of coke from the fridge, in the zone of the coke unloading, installing the pipe for supplying water into the space between the hollow heat exchanger (inner and outer shells of the refrigerator (U.S. Pat. Of the Russian Federation No. 2209825, IPC SW 39/10, op. 10.08.2002,).

The disadvantage of this refrigerator is a complex mounting structure of the Central pipe to a hollow heat exchanger (internal) body, the destruction of the nodes in its mounting due to cyclic dynamic loads during rotation of the refrigerator and thermomechanical load on a node of the transition of water from the annulus to the Central drainage pipe at the hot end of the refrigerator due to the action of high temperature coke at the entrance to the refrigerator.

The technical result, which is aimed by the invention, is to reduce the dynamic and thermo-mechanical loads, simplify the design and maintenance of the internal cylindrical hollow housing the refrigerator.

The specified technical result is achieved by the fact that in the proposed rotating the refrigerator for cooling coke, comprising outer and inner housings with micorphone space between them, with the inner housing provided with openings for loading and unloading of coke, and micorphone space is in communication with the inlet and outlet pipes for cooling water, placed in the zone of discharge of coke, according to the invention in markoconnor space installed deaf longitudinal partitions forming at least two sections for the supply of cooling water associated with the induction pipe, and two sections for removal of cooling water associated with the outlet pipe, with the above section in the download area of coke communicated between the holes.

Section communicated between the holes 12 in the loading area of coke for flow of water. The fridge is stocked screw elements 13 mounted on a screw line of the inner surface of the case 2 (for horizontal fridge) and longitudinal plates 14 (shown only in cross section n is 2).

The refrigerator in the first embodiment is as follows. Calcined coke with temperatures up to 1450°C flows through the inlet opening 3 into the internal cavity of the housing 2. During the rotation of the refrigerator cooled coke is moved to the discharge opening 4. The cooled coke is due to the coolant water through the introduction pipe 5 in micorphone space 8 in section 10 of the water supply, water flow in sections 10 water supply to the hot end of the refrigerator with an inlet opening 3, the overflow section 11, the flow through these sections end to the cold end of the refrigerator and output through the pipe 6 into the pipe 7 and the cooling system circulating water (not shown).
