[Abstract]:Loop heat pipe is an efficient two-phase heat control device, which is mainly used in aerospace thermal control and ground high heat flux electronic devices. The existing flat loop heat pipe has only one surface for heat dissipation. On the one hand, the unfavorable back heat conduction makes it difficult for the loop heat pipe to start under the condition of low heat load, and the other side of the evaporator also has the potential to dissipate heat. In view of the above deficiencies, a flat-plate methanol-copper double-sided evaporator loop heat pipe is proposed. Under the condition of gravity auxiliary inclination of 10 擄and heat sink temperature of 0 鈩，
