Abstract
An immersion cooling apparatus includes a mechanism for immersing a hot metal pipe with the axis thereof directed horizontally in a cooling tank containing cooling liquid, and a mechanism for locking the immersed pipe in position in the cooling tank. While the locking mechanism is preventing the pipe from moving, a nozzle extending toward the interior of the pipe in the direction of the pipe axis injects cooling liquid into the pipe. The cooling liquid thus injected flows completely through the pipe so that the pipe being cooled is not injured or bent.
Claims8
An immersion cooling apparatus for hot metal pipes comprising:
- a cooling tank for containing a body of cooling liquid in which the pipes are to be immersed for cooling;
- a plurality of skids extending from outside of the cooling tank downwardly into the cooling tank to a level below the level of the surface of the cooling liquid and being spaced in the direction of the length of the cooling tank for guiding the pipe into the tank along the skids;
- pipe supporting means in the tank at the lower end of said skids for supporting a pipe thereon;
- a pipe leveling means having pipe holding members which cross said skids and means on which said holding members are mounted for moving said holding members for causing a pipe moving downwardly along the skids into the tank to remain in a horizontal position;
- a cooling liquid nozzle in said tank aligned with the position of the axis of a pipe supported in said pipe supporting means and spaced from the adjacent end of a pipe supported in said pipe supporting means for injecting cooling liquid into the pipe, the space between the end of said cooling liquid nozzle and the position of the end of the pipe being such that cooling liquid around the end of a pipe will be sucked into the pipe and discharged from the other end of the pipe by the jet from the cooling liquid nozzle;
- and
- a source of cooling liquid under pressure connected to the cooling liquid nozzle for supplying cooling liquid to the cooling liquid nozzle.

- pipe supporting means in the tank at the lower end of said skids for supporting a pipe thereon;
- a pipe leveling means having pipe holding members which cross said skids for supporting a pipe on the skids in a horizontal position at least at one position along said skids as the pipe moves downwardly along the skids into the tank so tht the pipe remains in a horizontal position as it moves along said skids subsequent to said one position;
- a cooling liquid nozzle in said tank aligned with the position of the axis of a pipe supported in said pipe supporting means and spaced from the adjacent end of a pipe supported in said pipe supporting means for injecting cooling liquid into the pipe, the space between the end of said cooling liquid nozzle and the position of the end of the pipe being such that cooling liquid around the end of a pipe will be sucked into the pipe and discharged from the other end of the pipe by the jet from the cooling liquid nozzle;
