PURPOSE:To increase the length of a cooling water passage and improve cooling efficiency by a method wherein the inlet port and the outlet port of cooling water are provided on one of two tanks with a predetermined space while the tank between said outlet and inlet ports is partitioned by a bulkhead which circulates the cooling water reciprocally between both tanks at least by one turn. CONSTITUTION:The inlet port 93 and the outlet port 94 of cooling water are provided on a lower tank 91 and the tank between the outlet and inlet ports is partitioned by a bulkhead 92 whereby heated water, flowing into the half body T1 of the lower tank through the inlet port 93, ascends a cooling passage length l through water tubes 82-84 while radiating the heat thereof through fins 88 and the like and, thereafter, is collected in an upper tank 71. Then, the cooling water descends the cooling passage length l through the water tubes 85-87 while dissipating the heat thereof, then, is collected in the lower tank half body T3. The cooling water is reciprocated between the lower tank 91 and the upper tank 71 in such a manner whereby the cooling passage length (2l) may be obtained by the height of a radiator 7. According to this method, the cooling water passage length in the radiator device may be increased remarkably and cooling efficiency can also be improved. |
