船用列管式滑油、淡水冷却器(以下简称冷却器)是柴油机润滑系统和冷却系统的重要设备。这类冷却器由柴油机厂或船舶总体设计单位提出被冷却介质的流量、压力和温度等参数,由冷却器生产单位(或专业设计单位)设计出相应冷却面积和结构尺寸的冷却器,再进行生产。由于各种柴油机的上述参数差别很大,冷却器设计者的设计思想也不尽相同,致使冷却器的基本参数杂乱无章,尺寸参数繁杂不一,产品的通用性、互换性很差,不能经济地组织生产。
Marine tube lubricants, fresh water cooler (hereinafter referred to as the cooler) is a diesel engine lubrication system and cooling system of important equipment. This kind of cooler is proposed by the diesel engine factory or the ship’s overall design unit to set the parameters such as the flow, pressure and temperature of the cooling medium, and the cooler production unit (or professional design unit) designs the cooler with the corresponding cooling area and structure size, produce. As a result of the various parameters of diesel engines vary greatly, the design of the cooler designers are not the same, resulting in clutter of the basic parameters of the cooler, size parameters vary, the versatility of the product, poor interchangeability, can not be economical To organize production.
