400 Watt TEC-Based Cold Plate / Laser Diode Mount for High Power Pump Lasers and Arrays
The EHS-025 is an All-Air cooled heat sink for high power pump laser diodes. It offers 0.025ºC/w thermal resistance, and is capable of dissipating up to 400w of waste heat in a 22ºC typical lab environment. It is also designed for air-cooling of a wide array of high heat flux devices such as high power IGBT modules.
Fourteen embedded copper heat transfer pipes spread and remove laser waste heat throughout the structureFits in a 2U 19” rack mount chassis. The base plate acts as mini optical table with pre-tapped 4-40 threaded holes on 14.5mm x 14.5mm pattern. Optional clamps and shims enable users to place the diode anywhere on the base plate. The unit offers a removable bottom carrying plate and fan assembly, so users may incorporate the EHS core into OEM systems. The carrying plate provides pre-drilled holes for 8-32 screws or ¼-20 screws on 1” pattern for securing EHS-025 on any optical tables. A custom thermoelectric cold plate using EHS-025 as base provides up to 550w Qmax available. Fans may be PWM modulated to reduce noise for less demanding cooling scenarios
Laser Diode Mounting and Accessories
The cooling-core of EHS-025 consists of the mini-table base plate, 14 heatpipes and cooling fins all soldered together into a single piece. It is removable from EHS-025, enabling users to integrated into OEM systems.
The base plate of the cooling-core serves as a mini optical table. At 135mm wide x 253mm long x 12mm thick, it can accommodate all the popular high power lasers or multiple lower power lasers. The 4-40 threaded holes are on 14.5 x 14.5 grid.
The mounting slot of the optional clamps is sized to slide continuously through the entire length of the grid, always provide access to two 4-40 threaded holes, so that the diode can be clamped at almost any position.
Various optional shims are also available to accommodate the range of heights of popular diodes. The total height of the stack of clamp and shims should be about 0.5mm lower than the height of the diode, so that the deflection of the clamp will provide the clamping force necessary to press the diode on the base plate either directly or with thermal pad in between.
Clamp Part number and height:
Part C-14, H=13.5 for 14mm height
Part C-17, H=16.5 for 17mm height
Part C-21, H=20.5 for 21mm height
Part S-0.5, 0.5mm shim
Part S-1, 1mm shim
Part S-2, 2mm shim
Users are advised to place the diodes such that the source of the heat spans over as many heatpipes as possible to take advantage of the heatpipes.
