Latest Patents

David W Almgren holds a patent for a thermal control system designed for space shuttles. This system allows for individual temperature control of payloads through a liquid control loop that is in heat exchange relationship with both the payload and a radiator or shuttle cold plate. The system features a variable speed liquid pump that controls the heat transfer between the load and the radiator or cold plate. Additionally, the motor can be reversed to bypass the radiator through check valves. The radiator incorporates heat pipes seated in elongated, high thermal conductivity extrusions, secured by elongated springs. The motor utilized is a brushless DC motor, isolated from the pump by a magnetic clutch and thermal isolator. This motor is driven by a digital circuit that modulates pulse width to control speed effectively.
