The invention provides a double-chamber heat pipe capable of self-optimizing heat dissipation. The heat pipe comprises a primary chamber, a secondary chamber and a two-way steam switch group, wherein the primary chamber is connected with the secondary chamber through the two-way steam switch group. The filling ratios and the steam pressure of the two chambers are adjusted through opening and closing of the two-way steam switch group between the two chambers. Steam switches have different switching thresholds through adjusting heat power of an electric heating device on the outer wall of the secondary chamber. Compared with a common heat pipe, the double-chamber heat pipe capable of self-optimizing heat dissipation has the advantages that the filling ratio of the heat pipe can be adjusted through the two-way steam switch group between the double chambers to be matched with the heat source power and the heat flux density, thereby achieving the optimal heat dissipation efficiency.
