PROBLEM TO BE SOLVED: To provide a radiator in a liquid cooled system for an electronic apparatus which shortens a passage of an entire liquid cooled system thereby suppressing passage resistance and improving the heat radiation performance and the layout flexibility.SOLUTION: A liquid cooled system for an electronic apparatus includes: a cooling jacket 1 disposed on a surface of the electronic apparatus including a heater element; a radiator R allowing a liquid refrigerant circulating in the cooling jacket to flow in and radiating the generated heat to the exterior; and a circulation pump P disposed in a circulation passage 2 connecting the cooling jacket with the radiator and circulating the liquid refrigerant. The radiator includes: a heat exchange tube where the liquid refrigerant is flowed therein and a corrugate fin 3 is provided at the outer side; and a header tank 20 connected with the heat exchange tube. The header tunk is provided at a center part of the radiator, is divided into a refrigerant inflow chamber and a refrigerant outflow chamber with a dividing plate disposed therebetween, and is provided with a refrigerant inflow port 24 and a refrigerant outflow port 25 which are respectively located in the refrigerant inflow chamber and the refrigerant outflow chamber and are connected with the circulation passage. |
