Abstract (en)
[origin: EP3153771A1] The present invention describes a cooling device (100) for lighting modules, in particular LED lighting modules. Said cooling device (100) at least comprises a fluid jet generating unit (104), wherein the fluid jet generating unit (104) comprises a housing (202) and a fluid jet generating means (209) arranged in said housing (202) for generating fluid jets, wherein the housing (202) comprises at least two separated outlets (220, 222) for outputting said fluid jets, wherein the outlets (220, 222) are fluidly connected to said fluid jet generating means (209), and a heat-dissipating unit (102) attached to the housing (104) of said fluid jet generating unit (104), wherein the heat-dissipating unit (102) comprises at least one heat-dissipating element (103) having an outer surface (220) and an inner surface (224), wherein the heat-dissipating element (103) comprises at least one fluid communication element (108), in particular a plurality of holes or slits, for establishing a fluid communication between fluid adjacent the inner surface (224) and fluid adjacent the outer surface (220) for eliminating pressure differences between fluid adjacent the inner surface (224) and fluid adjacent the outer surface (220), wherein a first one of said outlets (222) is located adjacent the inner surface (224) of the heat-dissipating element and a second one of said outlets (218) is located adjacent the outer surface (220) of said heat-dissipating element (103) for causing pressure differences between fluid adjacent the inner surface (224) and fluid adjacent the outer surface (220).
