The reduction of cooling power required by the electromechanical coolant pump, radiator fan(s), and thermal valve demands real time control strategies.
w,min], the smart thermal valve is closed to reduce the coolant flow through the radiator and achieve the target [U.
This device acts as a one-way thermal valve, if the temperature is hotter outside than in the refrigerator heat is not transferred into the refrigerator.
In automatic transmissions, temperature changes cause both the viscosity and density of the fluid to vary, making possible two thermal valve applications.
To counter viscosity variations, a thermal valve may be inserted into the servo system that feeds or exhausts a clutch pack in the transmission.
The thermal valve responds to the lower temperature and opens up.

Thermal Valve Gate hot-runner probes, manifolds, and controls.
A compact "Universal Controller" that can run virtually any hot-runner system of any number of zones is new from Thermal Valve Gating.
Internally heated hot-runner probes employ patented Thermal Valve Gating process, where by a separate second heater at the tip of probes cycles on and off, providing absolute control at the gate.
Company's Thermal Valve Gating employs the conventional probe body heater found on all hot-runner systems, with the addition of its probe tip heater that cycles on and off.
