The invention provides a reversible loop heat pipe layout for satellite heat dissipation surface coupling, which comprises transverse heat pipes, a plurality of transverse heat pipes are pre-embedded in a + X-direction heat dissipation surface and a-X-direction heat dissipation surface in parallel, a plurality of longitudinal heat pipes are respectively arranged on the inner surfaces of the + X-direction heat dissipation surface and the-X-direction heat dissipation surface, and the longitudinal heat pipes penetrate through the transverse heat pipes; the reversible loop heat pipe comprises evaporators and liquid storages, the evaporators and the liquid storages are connected, the outer surface of each longitudinal heat pipe is provided with a set of evaporators and liquid storages, the evaporators and the liquid storages in different sets are connected through steam pipelines and liquid pipelines respectively, the transverse heat pipe is an 8-shaped double-hole omega-shaped channel heat pipe, and the transverse heat pipe and the transverse heat pipe are connected through a steam pipeline and a liquid pipeline respectively. And the longitudinal heat pipe is an I-shaped double-hole omega-shaped channel heat pipe. The reversible loop heat pipe has the advantages that the reversible loop heat pipe with the two evaporators connected in series is adopted, the heat transfer direction is variable, and therefore the thermal control system has the advantages of being high in layout flexibility, high in heat transfer efficiency, capable of greatly reducing the weight of the thermal control system and long in service life.
