Water supply module and electrical equipment cooling system comprising said water supply module

The invention relates to a water supply module and an electrical equipment cooling system comprising the same. The water supply module includes: a water storage tank in which two coolants having different temperatures are separated and accommodated so as not to be mixed with each other; a heat exchanger having a coolant passage through which two coolants flow, respectively, and a single refrigerant passage; a controller including a direction control valve capable of controlling the coolant to flow in six directions; and a first coolant pump and a second coolant pump connected to the controller, in which the flow rates of the two coolants are simultaneously controlled according to the operation of the directional control valve, and the electrical equipment cooling system is configured such that two electrical components of a water storage tank connected to the heat exchanger and the water supply module are individually cooled and heated, accordingly, each component of the cooling system is integrally connected
