Dual chamber loop heat pipe structure with multiple wick layers
A loop heat pipe structure includes a transport pipe, an evaporator, a first wick layer, a second wick layer, and a plurality of grooves. The transport pipe communicates with the evaporator. The evaporator has a bottom and internally defines a first chamber and a second chamber, and has a working fluid filled therein. The first wick layer is located on the bottom, and the second wick layer is located on and covers the first wick layer. The grooves can be selectively provided on the first wick layer or the bottom. The first and second wick layers are so designed that the situation of very high vapor pressure would not occur in the second chamber, enabling the loop heat pipe structure to have upgraded heat dissipation efficiency.
