Abstract
A cold plate is disclosed for cooling electronics within a missile. The cold plate includes a housing enclosing a compartment. An outlet manifold is inside the compartment. A wick is inside the compartment and is adjacent to the outlet manifold. A liquid inlet is fluidically connected to the wick. A vapor outlet fluidically connects the outlet manifold to atmosphere or space.
Claims18
A cold plate for cooling a heat source, the cold plate comprising:
- a housing enclosing a compartment;
- a liquid manifold inside the compartment;
- a vapor manifold inside the compartment;
- a wick forming an interface between the liquid manifold and the vapor manifold;
- an inlet fluidically connected with the liquid manifold;
- an outlet fluidically connecting the vapor manifold to atmosphere or space;
- and
- a liquid reservoir fluidically connected to the liquid inlet, wherein the liquid reservoir comprises an elastic liner that is collapsible and fluidically connected to the liquid inlet, and wherein the elastic liner is configured to:
- expand when filled with liquid;
- exert pressure on the liquid;
- and force the liquid into the liquid manifold.
