Abstract
A cutting tool that includes an elongated body with a first end and an opposing second end. A cutting edge is positioned at the first end. A heat pipe extends within an interior space of the body and has a first end in proximity to the cutting edge and a second end in proximity to the second end of the body. The interior space is enclosed within the body and comprises walls that extend around an interior space. The walls comprise a geometric configuration for a liquid within the heat pipe to move towards the first end of the heat pipe during rotation of the body.
Claims20
A cutting tool comprising:
- an elongated body comprising a first end and an opposing second end;
- a cutting edge positioned at the first end;
- a bore that extends into the body from the second end with the bore comprising a constant width, the bore comprising an end wall opposing the second end;
- a heat pipe positioned within the bore, the heat pipe defining an interior space of a tapered shape for a liquid within the heat pipe to move towards the cutting edge during rotation of the body;
- the heat pipe comprising a closed bottom end wall spaced apart from the bore end wall, an opposing open top end at the second end, and a continuous side wall that extends along the bore between the bottom end wall and the open top end;
- and
- the side wall having a thickness that increases from the closed bottom end wall to the open top end, as such, the width of the interior space decreases from the closed bottom end wall to the open top end.
A cutting tool comprising:
- a body comprising an elongated shape with a length that extends between a cutting edge at a first end and an opposing second end;
- a bore of constant width that extends into the body from the second end, the bore terminates at an end wall opposing the second end;
- a heat pipe positioned within the bore, the heat pipe comprising a closed bottom end wall spaced apart from the bore end wall, an opposing open top end at the second end, and a continuous side wall that extends along the bore between the bottom end wall and the open top end;
- and
- wherein an interior diameter of the heat pipe continuously tapers such that the interior diameter decreases in a direction going away from the closed bottom end wall towards the open top end of the heat pipe;
- and
- wherein the tapered width causes a liquid within the heat pipe to move towards the heat pipe closed bottom end wall during rotation of the body.
