Abstract: The temperature control apparatus comprises a heat exchanging unit and a working fluid. The heat exchanging unit is independently disposed and divided into a first heat exchanging portion disposed at a first environment and a second heat exchanging portion disposed at a second environment. The heat exchanging unit has a plurality of heat-dissipating fins and a pipe running in the first heat exchanging portion and then running in the second heat exchanging portion. The pipe has an inlet and an outlet disposed in the first and second heat exchanging portions respectively. The pipe has a larger pipe diameter around the inlet and the outlet, and has a smaller pipe diameter away from the inlet and the outlet. The smaller pipe diameter of the pipe has the capillary function for regulating the pressure of the working fluid in the first and second heat exchanging portions.

Abstract: A submerged combustion burner, a submerged combustion melter including the submerged combustion burner, and method of operating the submerged combustion burner are disclosed. The submerged combustion burner includes central burner tube and a heat pipe that surrounds and extends beyond a terminal end of the central burner tube. When received in a burner opening defined in a melting tank of a submerged combustion melter, the heat pipe of the submerged combustion burner is disposed between the central burner tube and the floor of the melting tank. The heat pipe transfers or pumps heat via a sealed working fluid to a cooling fluid that thermally communicates with the heat pipe exterior to the melting tank.

Abstract: Thermal management systems can include a thermoelectric component, a heat transfer unit, and a controller. The heat transfer unit has a chamber and microfeatures in the chamber that are positioned to receive a working fluid. 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 which is within +/−60° C. of the first temperature within a range of 0.5 seconds to 20 seconds.

Abstract: A heat pipe system, method, and heat sink system to enhance heat transfer from a heat-generating component. The method includes generating heat with the heat-generating component. The method also includes transferring at least a portion of the heat to at least a portion of a volatile fluid within one or more heat pipes. The method further includes modifying, dynamically, an active heat transfer region of the one or more heat pipes, thereby dynamically modulating heat transfer from the heat-generating component through the one or more heat pipes.

Abstract: A mesh capillary woven structure is applied to a two-phase fluid heat dissipation unit. The mesh capillary woven structure includes multiple latitudinal lines and multiple longitudinal lines. At least two longitudinal lines with different thicknesses are selectively arranged as a longitudinal line set. The single latitudinal line and one multiple longitudinal line set sequentially repeatedly intersect (and overlap with) each other and are collocated and woven with each other to form the mesh capillary woven structure. Accordingly, the mesh capillary woven structure has more voids with different sizes so that the mesh capillary woven structure has greater capillary attraction and better water collection (containing) ability to greatly enhance the heat transfer performance.
