Abstract
The invention relates to a method and apparatus for heat exchange, especially for cooling at solid surfaces. At the solid surfaces, a locally uniform convective heat exchange is achieved. According to the invention, a sink flow is superimposed on a circular flow of a fluid in a flow chamber (1) at a surface of a heat-conducting solid wall (9) by means of a distributor, forming a vortex sink flow. The heat exchange surface of the component (9) to be cooled is at the same time the base plate (8) of a flow chamber (1).
