THERMOSYPHON HEAT SINK
First Claim
1. A heat-dissipating device for contacting with a heating element, comprising:
- a condenser comprising a shell having a chamber and a through hole communicating with the chamber, and a main capillary wick disposed in the chamber; and
an evaporator comprising an evaporating section having a gas cavity, a gas conduit communicating with the through hole, and a liquid conduit communicating with the chamber and filling with liquid, wherein the liquid conduit is inserted in the gas conduit and has a hole communicating with the gas cavity, and an outer surface of the evaporating section is contacted with the heating element;
wherein a stepped area is formed at a location where the liquid conduit is assembled with the chamber, the liquid flows in the gas cavity and absorbs the heat generated from the heating element to be transformed into gas and flows in the chamber through the gas conduit, the gas is transformed into the liquid, gathered in the stepped area by cooling of the condenser and flows into the liquid conduit.

Abstract
A heat-dissipating device includes a condenser and an evaporator. The condenser includes a shell and a main capillary wick. The shell has a chamber and a through hole communicating with the chamber. The main capillary wick is disposed in the chamber. The evaporator has an evaporating section, a gas conduit and a liquid conduit. The evaporating section has a gas cavity, and the liquid conduit communicating with the chamber and filling with a liquid. The liquid conduit having a hole communicating with the gas cavity is inserted in the gas conduit and the gas cavity. A stepped area is formed between the liquid conduit and the chamber for gathering the liquid flowing into the liquid conduit.
