LASER EMITTER HEAT REGULATION SYSTEM Russian patent published in 1997 - IPC

FIELD: laser engineering. SUBSTANCE: system has heat exchanger with built-in axial-flow fan, circulating device in the form of centrifugal pump built up of case with inlet and outlet holes, impellers coupled with heat exchanger and with emission unit; heat exchanger is assembled of set of solid plates with slits forming ribs in plates and with channels provided therein. Channels are intercommunicating through two cavities at their ends, each plate cavity communicating with one of cavities of nearby plate. Ribs are of rhombic shape rounded off on tops and in each plate they are shifted through distance equal to half that between ribs; impeller and case are stepped through diameter. Case is provided, in addition, with holes in vicinity of impeller stage arranged tangentially and with inclination to axis of impeller revolution. EFFECT: improved design. 7 cl, 6 dwg
