Safe in all oceans of the world
Thousands of miles of dyke, collapsed in the anthill. For ships that need to sail continuously for a long time at sea, a small equipment failure can cause a series of fatal problems that seriously threaten the safety of the ship and its crew. 板式换热器：抗腐蚀板材，紧凑设计及较轻的重量使我们的设备适宜在海上航行。 Ruineng Haoyu Plate Heat Exchanger: Corrosion-resistant plates, compact design and light weight make our equipment suitable for sailing at sea.
换热设备作为船舶上的滑油冷却器、淡水冷却器、中央冷却器、柴油机冷却器、缸套水冷却器等主要设备，被广泛的应用在油轮，液化气船，集装箱船，散货船和工程船上，在船舶的航行过程中起到重要的作用。 Ruineng Haoyu heat exchange equipment is widely used as oil cooler, fresh water cooler, central cooler, diesel cooler, cylinder liner water cooler and other equipment on ships. It is widely used in oil tankers, liquefied gas ships, and container ships. , On bulk carriers and engineering ships, play an important role in the navigation of the ship. 换热设备的耐腐蚀性和高性能，长时间持续的运行考验了瑞能浩宇换热设备的安全和稳定。 Highly corrosive, fouling-prone seawater operating conditions have tested the resistance and high performance of Ruineng Haoyu heat exchange equipment, and long-term continuous operation has tested the safety and stability of Ruineng Haoyu heat exchange equipment.
Ship cooling water systems are usually open seawater systems, closed fresh water cooling systems, and central cooling systems. The central cooling system is separated from seawater and freshwater pipelines, which has less corrosion and cleanliness, low management costs, and strong system reliability. The high-temperature and low-temperature freshwater channels separately cool different ship equipment, making the system adaptable and improving equipment performance. .
The central cooling system is divided into high temperature hot fresh water and low temperature warm fresh water closed system. The former is used to cool the main unit, and the latter is used to cool hot fresh water and various coolers. The heated warm fresh water is cooled by an open seawater system in a central cooler. Therefore, using only one cooler using seawater as the cooling liquid simplifies the arrangement of the seawater piping system.
Most of the oil coolers are water-cooled, and are divided into three types: tube type, plate type and spiral copper tube type according to different structural shapes.
