An underground heat exchange system containing a cooling unit is provided to supply air having an intended temperature during unexpected temperature increase by using an outer cooling system. An underground heat exchange system containing a cooling unit includes a housing(10), an intake air space(16), an exhaust air space(17), a separator(23), a heat exchanger(18), a coolant heat exchanger(25), and an air passage(19). The housing includes a cooling water inlet(11), a cooling water outlet(12), a coolant inlet(21), a coolant outlet(22), an air inlet(13), and an air outlet(14). Cooling water inflows and outflows through the cooling water inlet and the cooling water outlet respectively. Coolant inflows and outflows through the coolant inlet and the coolant outlet respectively. Air flows in and out through the air inlet and the air outlet respectively. The sucked air space contains sucked air. The exhaust air space contains the air to be exhausted. The separator separates the cooling water and the coolant. The heat exchanger contains the cooling water. The coolant heat exchanger contains the coolant. The air passage connects the sucked air space and the exhaust air space.
