Micro-channel parallel flow loop heat pipe

The invention relates to a micro-channel parallel flow loop heat pipe which comprises an evaporation section and a condensation section. The evaporation section and the condensation section are arranged inside and outside a cabinet door of a sealed cabinet correspondingly. The evaporation section and the condensation section are the same in structure and each comprise a heat pipe assembly, a phase change working medium forms a circulation loop between the heat pipe assemblies of the evaporation section and the condensation section, heat in the cabinet is absorbed in the evaporation section through phase changes, the absorbed heat is released into the outside environment in the condensation section, and the aim of heat dissipation of the cabinet is achieved. The heat pipe assemblies and the cabinet door are fixedly connected and combined into a whole, the structural design is simple and reasonable, a traditional fan is replaced, the damage rate of a fan is reduced, and the labor and material cost is reduced. According to the micro-channel parallel flow loop heat pipe, it can be ensured that a cabinet system reaches the required heat dissipation power under the condition of closed space, and the problem that dust enters the cabinet to influence the work of internal modules is solved. Working medium circulation power depends on gravity and density differences, no driving component is needed, and energy consumption is low. The heat pipe assemblies have the high heat transfer efficiency and heat exchange coefficient, and the heat dissipation efficiency is effectively improved.
