Claim Text:
1. A heat dissipation pipe loop, comprising: an evaporator section, a liquid pipe connected to an end of the evaporator section at an upstream side of the evaporator section, a condenser pipe connected to an end of the liquid pipe distant from the evaporator section, and a gas pipe having an end connected to the condenser pipe and an opposite end connected to the evaporator section at a downstream side of the evaporator section, the evaporator section comprising an enclosure and a separation board received in the enclosure, the enclosure defining therein a receiving space, the separation board being mounted in the receiving space to divide the receiving space into a liquid chamber and a gas chamber, the liquid pipe being in communication with the liquid chamber such that liquid flowing along the liquid pipe is received from the upstream side into the liquid chamber of the evaporator section, the gas pipe being in communication with the gas chamber such that gas flows out of the gas chamber and into the gas pipe to move toward the downstream side, the separation board separating the liquid received in the liquid chamber and the gas contained in the gas chamber from each other; wherein the enclosure comprises a top board adapted to receive an external heat source to be positioned thereon and in direct contact therewith, the liquid received in the liquid chamber being in direct contact with the top board substantially in the entirety thereof to maximize heat transfer from the external heat source to the liquid to evaporate the liquid into gas that moves through the separation board into the gas chamber; and wherein the separation board that is mounted in the receiving space constrains the liquid in the liquid chamber from further movement toward the downstream side.
