The present invention provides a cooling system for a fuel tank, which is to control even cooling of a fuel tank after the fuel tank of a vehicle is formed. The cooling system for a fuel tank includes: a work die, wherein the fuel tank with an inlet and an outlet is loaded; multiple temperature measuring devices measuring the temperature of a divided part of the fuel tank by being installed on the work die; a refrigerant injection device injecting a refrigerant into the fuel tank by being connected to the inlet of the fuel tank and having multiple injection nozzles, wherein the each of the injection nozzles face the divided part of the fuel tank corresponding and the refrigerant injection device includes a control valve controlling a pressure or a flow rate of the refrigerant by each injection nozzle; and a controller receiving a temperature of every divided part of the fuel tank from the temperature measuring device and controlling the flow rate or the pressure of the refrigerant by each injection nozzle using a control valve. The controller controls the control valve. Therefore, the higher the temperature of the divided part of the fuel tank, the higher the flow rate or the pressure of the injection nozzle corresponding.
주입구와 배출구가 형성된 연료탱크가 로딩되는 작업다이; 작업다이 상에 마련되며 연료탱크의 분할된 부분의 온도를 측정하는 복수의 온도측정기; 연료탱크의 주입구에 연결되어 연료탱크 내부로 냉매를 주입하며, 복수의 주입노즐이 구비되고, 각 주입노즐은 대응하는 연료탱크의 분할된 부분을 향하도록 마련되며, 각 주입노즐별로 냉매의 유량 또는 압력을 제어하는 제어밸브가 구비된 냉매주입기; 및 온도측정기로부터 연료탱크의 분할된 부분마다 온도를 수신하고, 제어밸브를 통해 각 주입노즐별로 냉매의 유량 또는 압력을 제어하되, 연료탱크의 분할된 부분의 온도가 높을수록 대응하는 주입노즐의 유량 또는 압력이 높아지도록 제어밸브를 제어하는 제어기;를 포함하는 연료탱크 냉각 시스템이 소개된다.
