１項記載の冷却システム。[Claims for Utility Model Registration] (1) A cooling medium circulation path in which a cooling medium is circulated by a circulation means and forms a closed circuit, and a plurality of heat exchangers arranged in parallel within this cooling medium circulation path. A cooling system comprising: a variable capacity pump provided as the circulation means in the coolant circulation path; an on-off valve provided upstream of each of the plurality of heat exchangers; and a cooling system comprising the plurality of heat exchangers. A cooling system comprising: a differential pressure detector that detects a pressure difference between an upstream side and a downstream side of the variable displacement pump; and a controller that controls a discharge amount of the variable displacement pump based on the detection result. (2) The cooling system according to claim 1, wherein the on-off valve is an automatic on-off valve that opens and closes in response to an operation signal from a cooled object of the heat exchanger.
