LOOP HEAT PIPE STRUCTURE WITH LOW-PROFILE EVAPORATOR
First Claim
Patent Images
1. A loop heat pipe structure, comprising:
- an evaporator having a first chamber, a first wick layer, a bottom and a plurality of grooves;
the first wick layer being provided in the first chamber to thereby define a first main chamber and a first secondary chamber in the first chamber;
the first wick layer having a working fluid filled therein; and
the grooves being selectively provided on any one of the first wick layer and the bottom; and
a first pipe having a first inlet and a first outlet;
the first inlet internally defining a second chamber and being connected to a wall of the evaporator to communicate with the first wick layer; and
the first outlet being connected to another wall of the evaporator to communicate with the first secondary chamber.

Abstract
A loop heat pipe structure includes an evaporator and a first pipe. The evaporator has a first chamber, a first wick layer, and a bottom. The first wick layer is provided in the first chamber. The first pipe includes a first inlet and a first outlet communicably connected to the evaporator. The first inlet internally defines a second chamber communicable with the first wick layer. By providing the second chamber outside the evaporator, the evaporator can have a reduced overall height without creating very high vapor pressure in the evaporator, enabling the loop heat pipe structure to have upgraded heat dissipation efficiency.
