The invention discloses a soil heat balance device for a soil source heat pump. The soil heat balance device comprises multiple soil source heat pump buried pipes vertically buried in the soil and multiple gravity heat pipes vertically buried in a burying area of the soil source heat pump buried pipes. The gravity heat pipes are provided with cooling fins which are tree-like cooling fins. Tree-like cooling fins are arranged on the outer wall of a condensing section of the air side, the tree-like cooling fins can enlarge the cooling area of the condensing section of the air side, and the condensing effect is improved. Tree-like cooling fins are arranged on the outer side of a condensing section of the soil side, the radiating area of the condensing section of the soil side can be enlarged through the tree-like cooling fins, and the condensing effect is improved. The tree-like cooling fins symmetrically extend outwards in a radial shape with the axes of the gravity heat pipes as the centers correspondingly and
