PROBLEM TO BE SOLVED: To provide a combine-integrated main engine heat exchanger with both functions of coolers and heaters which gives priority to control of a temperature control valve of the cooler side for cooling fresh water of a main engine and does not perform cooling at less than the required cooling water temperature of the main engine, and always controls the temperature control valve of the heater side at greater than or equal to the required temperature, with respect to control of the temperature control valve of the cooler side and temperature control valve of the heater side.SOLUTION: A heat exchanger to cool a main marine engine consists of a fresh water region where fresh water circulates to cool the main engine, a cooling seawater region where the outboard seawater to exchange heat in the fresh water region is taken in for circulation, and a vapor or heating medium region where a vapor or heating medium from the heat source of inboard equipment is taken in for circulation, the fresh water region is provided with the cooling seawater heat-exchanging tubes 6a, 6b, 6c extending from the cooling seawater region and exchanging heat between the fresh water and the cooling seawater in the cooling sea water region, and the heat medium heat-exchanging tubes 10a, 10b, 10c extending from the vapor region or heat medium region and exchanging heat between the vapor or heat medium and the fresh water in the fresh water region.SELECTED DRAWING: Figure 1
【課題】冷却器及び加熱器の両機能を持った一体型のコンバイン型主機熱交換器の冷却器側の温調弁と加熱器側の温調弁の制御に関し、主機の冷却清水の冷却器側の温調弁制御を優先し、主機の要求冷却水温度以下では冷却を行わず、常に必要温度以上で前記加熱器側の温調弁を制御する一体型のコンバイン型主機熱交換器の提供。【解決手段】船舶の主機関を冷却する熱交換器で、前記主機を冷却する清水が循環する清水域と、当該清水域で熱交換する船外海水を取り込み循環させる冷却海水域及び船内装備熱源からの蒸気又は熱媒を取り込み循環させる蒸気又は熱媒域とからなり、前記清水域には、前記冷却海水域から延び当該清水域内で前記冷却海水と前記清水との間で熱交換を行う冷却海水熱交チューブ6a,6b,6c及び前記蒸気又は熱媒域から延び当該清水域内で前記蒸気又は熱媒と前記清水との間で熱交換を行う熱媒熱交換チューブ10a,10b,10cとを備えた。【選択図】図1
