The disclosure discloses a cooling system and an automatic coolant injection method for the cooling system. The cooling system includes a heat exchanger; a converter; a liquid cooling pipeline; a coolant tank with a liquid-level sensor; an injection pump for injecting coolant from the coolant tank into the liquid cooling pipe; and a control unit. When liquid level of the coolant tank reaches an upper threshold, the injection pump injects coolant into the liquid cooling pipeline. When pressure of the coolant in the liquid cooling pipe reaches an upper static liquid pressure threshold, the control unit turns off the injection pump, and executes the turning-on and turning-off operations of the circulation pump with a preset circulation period. The circulation pump forces the coolant to circulate in the liquid cooling pipeline when being turned on.

The disclosed technology includes methods of extracting geothermal energy, generally comprising the steps of: insertion of a thermal mass into a Heat Absorption Zone, absorbing heat in thermal mass, raising the thermal mass to a Heat Transfer Zone, and transferring the heat from the thermal mass. The acquired heat can be used to generate electricity or to drive an industrial process. The thermal mass can have internal chambers containing a liquid such as molten salt, and can also have structures facilitating heat exchange using a thermal exchange fluid, such as a gas or a glycol-based fluid. In some embodiments, two thermal masses are used as counterweights, reducing the energy consumed in bringing the heat in the thermal masses to the surface. In other embodiments, solid or molten salt can be directly supplied to a well shaft to acquire geothermal heat and returned to the surface in a closed loop system.
