Method for cooling a component and appliance for carrying out the method
First Claim
1. A method for cooling a thermally loaded component having a plate-type outer wall and a duct wall parallel to the outer wall defining a cooling duct therebetween, a first cooling section comprising a portion of the outer wall and a second cooling section adjacent to the first cooling section comprising the cooling duct, the method comprising the steps of:
- supplying a cooling air flow from a cooling air supply;
dividing the cooling air flow into a main flow and a by-pass flow, the main flow being directed to impinge on the outer wall in the first cooling section, wherein the main flow is deflected at the first cooling section toward the cooling duct, and the by-pass flow being directed to the cooling air duct without contacting the outer wall in the first cooling section;
guiding the by-pass flow to the cooling duct to recombine with the main flow; and
directing the recombined cooling air flow in the cooling duct parallel to the outer wall.

Abstract
In a method for cooling a thermally loaded component (1) with a plate-type outer wall (2), in which method cooling air is supplied, in a first cooling section (A) of the component (1), through a cooling air supply (5) in the direction towards the outer wall (2) and is deflected laterally before the outer wall (2) and in a second cooling section (B) is further guided parallel to the outer wall (2) in a laterally adjoining cooling air duct (3) for the purpose of further cooling, homogenization of the cooling is achieved wherein, in order to reduce the impingement cooling in the first cooling section (A), the cooling airflow coming from the cooling airsupply (5) is subdivided into a main flow and a by-pass flow, the main flow is guided directly along the outer wall (2) of the component (1) to the cooling air duct (3), the by-pass flow is guided to the cooling air duct (3) without contacting the outer wall (2) and both partial flows are recombined at the inlet to the cooling air duct (3).

4. An apparatus for cooling an outer wall of a thermally loaded component, comprising:
-
a cooling air supply duct for guiding cooling air from a cooling air supply to the outer wall of the component; a duct wall disposed adjacent to the outer wall to define a cooling air duct bounded by the outer wall and the duct wall, the cooling air duct having an inlet communicating with the supply duct; and a partition disposed parallel to and spaced from the outer wall and extending from the cooling air supply duct to the inlet of the cooling duct, the partition defining a main duct adjacent to the outer wall and a by-pass duct parallel to the main duct and separated from the outer wall by the partition. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
