Abstract
A wick structure and a loop heat pipe using same are disclosed. The loop heat pipe includes an evaporation chamber, the wick structure and a condensate line. The wick structure is disposed in the evaporation chamber. The evaporation chamber has an outlet and an inlet. The wick structure has a main body, and a plurality of grooves is axially formed on an outer peripheral surface of the main body. The grooves respectively have an open side and a closed side. The open side has a width smaller than that of the closed side. The grooves having the above configuration enable the loop heat pipe to have increased vapor-liquid circulation efficiency.

A wick structure, comprising:
- a main body having a plurality of grooves and a plurality of non-grooved sections, the plurality of grooves being formed and axially extended on an outer peripheral surface of the main body, the plurality of non-grooved sections being formed between the two grooves;
- the grooves respectively having an open side being a continuous open face and a closed side being a continuous flat surface, and the open side having a width smaller than that of the closed side;
- and the non-grooved section having a width larger than that of the closed side of the groove.
A loop heat pipe, comprising:
- an evaporation chamber having an outlet and an inlet located at two opposite ends thereof;
- a wick structure disposed in the evaporation chamber and including:
- a main body having a plurality of grooves and a plurality of non-grooved sections, the plurality of grooves being formed axially extended on an outer peripheral surface of the main body, the plurality of non-grooved sections being formed between the two grooves;
- the grooves respectively having an open side being a continuous open face and a closed side being a continuous flat surface, and the open side having a width smaller than that of the closed side;
- and the non-grooved section having a width larger than that of the closed side of the groove;
- a condensate line having a first end and a second end, which are connected to the outlet and the inlet, respectively, of the evaporation chamber;
- and
- a working fluid filled in the evaporation chamber and a part of the condensate line.
