Local control of heat flow to more accurately regulate machine temperatures

A temperature regulation system (100), comprising

• a reservoir (112) having a fluid with a controlled temperature of a first value;
• a piping system (101) configured to deliver the fluid from the reservoir to one or more elements needing temperature control;
• a heat generating device (110) disposed at a location at or near an element needing temperature control, the heat generating device being configured to apply heat to control the element needing temperature control;
• and
• a local controller (116) configured to activate the heat generating device in accordance with a feedback sensor (114) such that the heat generator device applies heat to increase the temperature above the first value to locally and accurately maintain a set point temperature at the element needing temperature control.

A method for regulating temperatures locally for machine elements, comprising:

• providing a reservoir (112) common to a plurality of flow paths through an apparatus, the reservoir having a fluid with a controlled temperature of a first value;
• delivering the fluid (212) from the reservoir to elements needing temperature control;
• and
• generating a thermal change (110) at a location at or near the elements having a need for temperature control by generating or removing heat at or near the elements by sensing a local temperature and controlling a heat generating/removal device in accordance with a set point temperature such that the heat generating/removal device controls the temperature of the elements locally to each element to accurately maintain the temperature relative to the first value and independently of the other elements.
