Thermal Solutions


7StarLake Advanced Thermal Solutions

From ships at sea to high-altitude Drone, 7StarLake ATS solutions enable
electronics survivability in the harshest environments. As an ever-increasing number of data acquisition methods are utilized in military and aerospace, the need to convert that rising data tide into precise, real-time action only escalates.
Applications like object targeting , ground vehicles tracking, thermal image monitoring, and multiple simultaneous sensors feeds. When a wealth of such sources need aggregation and immediate analysis, potentially with graphical visualization output to any number of displays, VPX-based systems can ensure proven solutions.


Conduction Cooled – 7SL-3500CC

Conduction cooled SBC have traditionally been deployed in applications where heat evacuation with an airflow is impractical.

  • As the most common heat-transfer device available, heat pipes can manage the transfer of heat between two solid interfaces effectively. Combining the advantages of thermal-conductivity and phase transition, heat pipes are extremely light-weight compared with traditional cooling methods.
  • For the highest thermal dissipation and thermal density, heat pipes can be very effective in conduction cooled environments.
  • The heat pipes are embedded in a symmetrical topology from the sidewall, allowing the assembly to be less sensible to gravity or acceleration.



Force Air Conduction Cooled – 7SL-3500FA

  • 7SL-3500 Hybrid conduction cold plate assisted by forced air sets with aggregate power demands over 300W
  • Internal recirculation fans ensure dry air is forced across conduction or air-cooled payload modules, minimizing hot-spots and dissipating heat homogeneously


Liquid Cooled – 7SL-3500LC

Advanced conduction liquid cooling systems that enables higher powered, compact electronics in ruggedized military, aerospace applications.

7SL-3500-LC is a VPX-REDI Liquid-cooled enclosure utilizing side-wall cooling within the enhanced wedge-lock guide rails (increased 50% contact area) cooling of standard conduction Liquid Cooling Hardware Implementations. In order to effectively reduce overall temperature and prevent the leakage of the liquid, 7StarLake innovated a unique heat exchanger which integrating Conduction Liquid Cold Plate (C.L.C.P.) building in most advanced “Gun Drilled”, which with 4 pipes (each pipe 10mm x 10mm x 400mm) to dissipate max 1KW heat on the 3/4 ATR system.
