A heat pipe comprises a condenser, an evaporator, a working fluid, a displacement vessel and at least one connecting pipe. The volume available for the working fluid inside the displacement vessel is adjustable, said volume being adapted to change by a rotating movement of a body. In one embodiment external heat pipes allow several different heat sources to be connected. Advantages include that the capability of transferring heat can be adjusted and fine tuned to the desired value. Less force is required to rotate the body inside the displacement vessel. No energy input is required to hold the body in a desired position. The construction is simple and inexpensive to manufacture. In particular the construction is easy to manufacture in different volumes, since the diameter of the displacement vessel and rotating body can be the same but with a longer displacement vessel. |

1. A heat pipe, being a closed system and comprising a condenser, an evaporator, and a working fluid, wherein the condenser and the evaporator are connected to a displacement vessel with at least one pipe,
wherein the heat pipe further comprises a space in the displacement vessel, wherein the volume available for the working fluid in liquid state inside the space is adjustable, said space being adapted to shift between one first available volume (V1) and at least one second smaller available volume (V2), wherein the condenser is situated above the space in relation to the gravitational force and the evaporator is situated below the space in relation to the gravitational force, wherein the heat pipe is adapted so that working fluid in liquid state can flow under influence of gravitational force from the condenser via the displacement vessel to the evaporator, wherein a body is adapted for a rotating movement inside the displacement vessel and is adapted to have a first position (P1) so that the space (3b) has the first available volume (V1), and wherein the body further is adapted for a rotating movement to at least one second position (P2) so that the space (3b) has the smaller second available volume (V2). |
