Plate to air thermal management assemblies like our range of direct cooling kits are the ideal solution for photonics cooling when a solid state heat source like a laser diode needs to be cooled and temperature stabilized by a compact and maintenance free cooling device.
Driven either by peltier or direct evaporation of a refrigerant compressor circuit our mDC-KITs cool and stabilize the laser mounting plate to a set temperature. Heat from the laser source and from the cooling engine (peltier respectively compressor) is dissipated “directly” to the air – there is no water circuit that requires maintenance, occupies space and bears risk of corrosion. Our thermoelectric mini direct cooling kit has a nominal 120 W of cooling capacity and our compressor mini direct cooling kit can be configured for 100 to 700 W of maximum cooling capacity.
mDC-T-KITS - mini direct cooling thermoelectric kits
Our mDC-T-KITs come with a 108 mm x 108 mm mounting plate that can be worked on, i.e. individual mounting patterns can be drilled by the customer himself. The peltier modules can be configured for either 12 or 24 VDC. Depending on cooling requirements the 60 x 60 mm fans speed can be reduced for quiet operation.
mDC-C-KITs - mini direct cooling compressor kits
Our mDC-C-Kits replace recirculating chillers in applications where a compact and maintenance free cooling device is required. The laser mounting plate can be a customized evaporator plate for highest efficiency reaching COP values of up to 5 or a mounting plate that can be worked on, i.e. individual mounting patterns can be drilled by the customer himself. Our refrigerant circuits are carefully designed and allow for a robust control behavior. When lasers are switched ON or OFF overshoot and undershoot typically do not exceed +/-1 K. Temperature stability in continuous operation is +/-0,1 K. The set temperature range is from 15 to 25°C. Currently R134a is used as refrigerant which is inert, non-toxic and non-inflammable. R600a – isobutane – would also be available. The compressors are inverter driven, power supply either 240 VAC, 120 VAC or 12 VDC.
