Abstract

The invention discloses a flat evaporator structure and a loop heat pipe with the flat evaporator structure, the loop heat pipe has an evaporation section arranged on a heat source and a conduction section connected with a condensation section, the evaporation section includes an enclosed containment structure and a capillary structure, and has a bottom in which a channel structure is formed, and a liquid inlet and a gas outlet are arranged in a lateral margin of a container body to respectively connect a gas passage and a liquid passage, so that when a working fluid is heated by the heat source to become vapor, the vapor moves through the gas outlet and the gas passage to a condensing device in the condensation section where the vapor is cooled and converted back to the original form of the working fluid that is then guided through the liquid passage back to the enclosed containment structure for next cycle.

Description

technical field [0001] The invention relates to a loop heat pipe, in particular to a loop heat pipe with a flat plate evaporator structure. Background technique [0002] Due to the progress of the semiconductor process, the number of wires on the chip has been increasing. In order to accommodate these wires, the area after packaging is often several times the die area. Therefore, the heat on the surface of the package is not evenly distributed, and it is easy to form hot spots (Hotspot) and then cause chip damage due to uneven thermal stress. The role of the heat pipe is to quickly guide the heat to other heat sinks, and then remove the heat through the heat dissipation module. The current heat pipe design is mostly used in the heat dissipation of notebook computers, including the following methods: [0003] (1) Forced air cooling; [0004] (2) Forced liquid cooling; [0005] (3) heat pipe phase change heat dissipation; [0006] (4) Refrigerator heat dissipation; [000...
