TL;DR: In this article, a combined numerical and experimental study is performed to analyze the feasibility of using heat pipe cooling in drilling applications, and the results of this study can be used to define geometrical parameters for optimal design and the setup for further analysis.
Abstract: A combined numerical and experimental study is performed to analyze the feasibility of using heat pipe cooling in drilling applications. A parametric study is conducted to analyze the effect of different geometrical parameters expected for a heat pipe drill configuration, such as depth of the heat pipe within the drill, heat pipe diameter, heat flux input magnitude and length of the heat input zone. In this model, it is assumed that the drill is subjected to a static heat source which verifies the analysis and feasibility of using heat pipe cooling in drilling operations. The performance of the heat pipe drill model is approximated using a solid cylinder model of pure conduction. To validate the assumptions, numerical results are compared with experimental data that are based on the solid cylinder model. Both the numerical and experimental studies show that the use of a heat pipe in a drill can reduce the temperature field significantly. The results of this study can be used to define geometrical parameters for ‘optimal’ design and the setup for further analysis.

TL;DR: In this article, a heat pipe traverses a through opening in the base plate and extends along a receptacle in a base plate facing the heat source, this portion preferably defining the heat pipe evaporator.
Abstract: A heat transfer device such as a heat sink has one or more heat pipe tubes mounted in a base plate. The heat pipe tubes have a working fluid in a vessel with a wicking material between an evaporator and condenser. The heat pipe traverses a through opening in the base plate and extends along a receptacle in the base plate facing the heat source, this portion preferably defining the heat pipe evaporator. The heat pipe has legs extending perpendicularly from the base plate, and preferably hold spaced heat transfer fins, the legs forming the condenser part of a stacked tower of fins on the base plate. Preferably two or more heat pipes are provided in the form of U-shaped or L-shaped tubes that are flattened along the underside of the base plate to bear against the heat source.
