Constant conductance heat pipe assembly for high heat flux
A heat pipe assembly that includes at least one axial groove heat pipe and at least one porous media heat pipe. The porous media heat pipe may be embedded into a flange of the axial groove heat pipe, or embedded into a wall of the axial groove heat pipe, or embedded into another bore of the axial groove heat pipe. The evaporator of the at least one porous media heat pipe may be located remotely and can accept a high heat flux, while a condenser of the at least one porous media heat pipe is attached to the axial groove heat pipe.
1. A heat pipe assembly comprising at least one axial groove heat pipe, and at least one additional heat pipe with a porous wick in an evaporator, the evaporator being located remotely from the axial groove heat pipe and can accept a heat flux of at least 50 W/cm 2 , a condenser of the at least one additional heat pipe being attached to the axial groove heat pipe.
2. The heat pipe assembly as recited in claim 1 , wherein the porous wick of the at least one additional heat pipe extends along the entire length of the heat pipe assembly.
3. The heat pipe assembly as recited in claim 1 , wherein the porous wick of the at least one additional heat pipe is provided in the evaporator and the at least one additional heat pipe has a different wick in an adiabatic and/or the condenser sections.
4. The heat pipe assembly as recited in claim 1 , where the at least one additional heat pipe is embedded into a flange of the axial groove heat pipe.
5. The heat pipe assembly as recited in claim 1 , where the at least one additional heat pipe is embedded into a wall of the axial groove heat pipe.
