Abstract
Thermal management systems including a thermoelectric component, a two-phase heat transfer unit, and a controller are disclosed herein. The heat transfer unit has a phase-transition chamber and microfeatures in the phase-transition chamber that induce capillary forces to a working fluid that drives the working fluid through the phase-transition chamber. The controller is configured to operate the thermoelectric component and the heat transfer unit such that the heat transfer unit cools one side of the thermoelectric component to a first temperature and the thermoelectric component changes the temperature of a target material on its other side to a second temperature of +/−60° C. of the first temperature within 0.5-20 seconds.
Claims23
A thermal management system, comprising:
- a thermoelectric component having a first side configured to be thermally coupled to a target material and a second side opposite the first side;
- a two-phase heat transfer unit thermally coupled to the second side of the thermoelectric component, the two-phase heat transfer unit having 1) a phase-transition chamber having an inlet region and an outlet region, 2) microfeatures in the phase-transition chamber spaced apart from each other such the microfeatures induce capillary forces to a working fluid that drives the working fluid from the inlet region of the phase-transition chamber to the outlet of the phase-transition chamber, 3) an inlet through which the working fluid flows into the two-phase heat transfer unit in a liquid phase, and 4) an outlet through which at least a portion of the working fluid flows out of the two-phase heat transfer unit in a vapor phase;
- and
- a controller configured to operate the thermoelectric component and the two-phase heat transfer unit such that the two-phase heat transfer unit cools the second side of the thermoelectric component to a first temperature and the thermoelectric component changes the temperature of the target material to a second temperature within a range of 0.5−to 20 seconds, and wherein the second temperature is +/−60 ° C. of the first temperature.
A semiconductor device, comprising:
- a semiconductor component having integrated circuity;
- and
- a thermal management system including—
- (a) a thermoelectric component having a first side configured to be thermally coupled to the semiconductor component and a second side opposite the first side;
- (b) a two-phase heat transfer unit thermally coupled to the second side of the thermoelectric component, the two-phase heat transfer unit having 1) a phase-transition chamber having an inlet region and an outlet region, 2) microfeatures in the phase-transition chamber spaced apart from each other such the microfeatures induce capillary forces to a working fluid that drives the working fluid from the inlet region of the phase-transition chamber to the outlet of the phase-transition chamber, 3) an inlet through which the working fluid flows into the two-phase heat transfer unit in a liquid phase, and 4) an outlet through which at least a portion of the working fluid flows out of the two-phase heat transfer unit in a vapor phase;
- and
- (c) a controller configured to operate the thermoelectric component and the two-phase heat transfer unit such that the two-phase heat transfer unit cools the second side of the thermoelectric component to a first temperature and the thermoelectric component changes the temperature of the semiconductor component to second temperature.
