置。[Claims for Utility Model Registration] A heat exchanger that exchanges heat through cooling water, such as a cooling roller of a printing press, a first tank from which cooling water is sent from the heat exchanger, and cooling water from the first tank. a cooling water circulation circuit consisting of a pump that sends the cooling water to the heat exchanger, and a cooling water circulation circuit that is constantly supplied with cold water at a temperature lower than the cooling water setting temperature on the upstream side of the heat exchanger, and at which the cooling water is at a predetermined water level or higher in the first tank. and a second tank connected to allow flow into the cooling water circulation circuit, and a three-way valve connected to the second tank is interposed in the circulation path between the first tank and the pump of the cooling water circulation circuit, The cooling water of the tank and the cold water of the second tank are provided so as to be able to be sent to the heat exchanger side, and the amount of sending from the first and second tanks of the three-way valve is adjusted based on the temperature of the cooling water detected at the upstream part of the heat exchanger. A cooling water circulation device characterized by being equipped with a temperature controller for operation.
