To provide equipment and a method for spraying a cryogen wherein the cryogen is sprayed on a heat load from one or more spray nozzles within a spraying zone.
A thermally conductive element is disposed below an article and it has a surface formed in such dimensions as to catch the liquid content of a cryogen oversprayed and thereby to evaporate the oversprayed by the direct heat transfer therewith. In another mode, equipment and a method using a flow network wherein a flow of the liquid cryogen is divided into first and second auxiliary flows are provided. The second auxiliary flow is evaporated in a branch of the network and joined to and mixed with the first auxiliary flow and thereby a two-phase flow of the cryogen is generated. Then, the cryogen is sprayed as the two-phase flow.
