FLUID FLOW HEAT EXCHANGER, PARTICULARLY FOR ELECTRON TUBES

摘要

A fluid flow heat exchanger comprising a thermally conductive porous body (21) contacting at least one portion of a part (20) to be cooled. The fluid flows through said porous body (21). The porous body has pores which cause the fluid to change direction and are large enough to minimise head loss as the fluid flows through the porous body (21). Said heat exchanger is particularly useful for electron tubes.
