Patent number: 9882646Abstract: A heat removal system for use in optical and optoelectronic devices and subassemblies is provided. The heat removal system lowers the power consumption of one or more active cooling components within the device or subassembly, such as a TEC, which is used to remove heat from heat generating components within the device or subassembly. For any particular application, the heat removal system more efficiently removes the heat from the active cooling component, by using a heat transfer assembly, such as a planar heat pipe type assembly. The heat transfer assembly employs properties like, but not limited to, phase transition change and thermal conductivity to move heat without external power. In some embodiments, the heat transfer assembly can be used to allow the active cooling component, such as a TEC to be removed, leaving the heat transfer assembly to remove the heat from the device or subassembly.Type: GrantFiled: May 25, 2016Date of Patent: January 30, 2018Assignee: OE SOLUTIONS AMERICA, INC.Inventor: Daniel Jacob Blumenthal
