Abstract:
1. An automatic self-adjusting, self-powered, over-temperature protection apparatus for limiting fluid temperature on a single flow path in flowing fluid systems, comprising: a flow splitter at the inlet that allows inlet fluid to the apparatus to travel to the start of two flow paths through the apparatus; a mixing valve near the outlet that opens and closes in response to the fluid temperature at the mixing valve outlet, combines fluid from the flow paths and directs the flow to the outlet of the apparatus; a low-heat-dissipating flow path, connected to the flow splitter and to the mixing valve that has 0% or almost 0% of the flow through the apparatus when the temperature at the mixing valve outlet is above an upper set-point temperature, 100% or almost 100% of the flow through the apparatus when the temperature at the mixing valve outlet is below a lower set-point temperature, and a percentage between 0% and 100% of the flow through the apparatus when the fluid temperature at the mixing valve outlet is between the lower and upper set-point temperatures; and a high-heat-dissipating flow path, connected to the flow splitter and to the mixing valve in parallel with the low-heat-dissipating flow path, that has 0% or almost 0% of the flow through the apparatus when the temperature at the mixing valve outlet is below a lower set-point temperature, 100% or almost 100% of the flow through the apparatus when the temperature at the mixing valve outlet is above an upper set-point temperature, and a percentage between 100% and 0% of the flow through the apparatus, the balance of flow through the low-heat-dissipating flow path, when the fluid temperature at the mixing valve outlet is between the lower and upper set-point temperatures.
