Title: CONVERSION UNIT HAVING A PLURALITY OF CONVERSION MODULES, COMMISSIONING METHOD OF THE CONVERSION UNIT, AND OPTICAL ARRANGEMENT COMPRISING SUCH A CONVERSION UNIT
Abstract:
The invention relates to conversion modules (20/ 20') disposed adjacent to each other in a conversion unit (50/ 50') in at least one arrangement direction (35, 36), forming a conversion arrangement (30/ 30') in order to convert electrical power into radiant energy, or vice versa, at a scalable scope. Said modules are supplied with coolant for cooling by means of a coolant feeding and discharge device (40). In the area of a heat absorption surface (21*), one semiconductor conversion element (10/ 10') for forming a conversion module (20/ 20') is mounted on each heat transfer body (21), said body being divided into three segments: the heat absorption segment (21a) having the heat absorption surface (21*), a heat dissipating segment (21c) having a heat dissipating surface (26*) in at least one recess and wetted by the coolant, and a heat transfer segment (21b) disposed between the heat absorption segment (21a) and the heat dissipating segment (21c). The conversion arrangement (30/ 30') has an opening (27) in the heat dissipating segment (21c) connected to the recess present therein, and facing the conversion module (20/ 20') adjacent thereto in the arrangement direction. The heat transfer segment (21b) comprises at least one sealing surface (24) providing sealing, contributing to entrapment of coolant in the coolant flow passages (37) of conversion modules (20/ 20') adjacent to each other between heat dissipating segments (21c). The coolant flow is such that the fluidic flow through at least two groups of conversion modules (20/ 20') is in parallel. The conversion modules (20/ 20') can be designed both as diode laser components (20) and as solar modules (20').
