背景技术Background technique
随着国际海事组织以及国际社会对船舶的节能减排的要求提高，以及EEDI的推出和生效，对船舶的性能、单位有效提出了更高的要求；并且由于船舶燃油消耗巨大，导致船舶运营成本越来越高。因此，船舶在建造中，合理的设计绿色节能装置，能很好的降低能耗、减少废气排放，从而减少设备维护费用，降低船舶运营成本。目前船上很多常规热交换器的设计和布置，都需要独立设计和安装一套泵组循环设备，而且，需要占用和消耗船舶能源。如果能发明一种船舶绿色节能热交换器既能简化系统设计和设备，又能降低船舶能耗，减少船舶的废气排放，必然能快速推进绿色环保船舶的发展。普通的海水热交换器，需要有一套海水循环系统来支撑，配备海水滤器、海水冷却泵、海水管路、阀门等一系列管路附件。现有的海水热交换器占用船舶空间、增大了船舶成本和能耗，给船舶人员船上工作和维护带来不便。With the increasing requirements of the International Maritime Organization and the international community for energy saving and emission reduction of ships, and the launch and entry into force of EEDI, higher requirements are put forward for the performance and unit effectiveness of ships; and due to the huge fuel consumption of ships, the operating costs of ships Higher and higher. Therefore, during the construction of ships, reasonable design of green energy-saving devices can reduce energy consumption and exhaust emissions, thereby reducing equipment maintenance costs and reducing ship operating costs. At present, the design and layout of many conventional heat exchangers on board require the independent design and installation of a set of pump circulation equipment, and the need to occupy and consume the energy of the ship. If a green and energy-saving heat exchanger for ships can be invented, it can not only simplify the system design and equipment, but also reduce the energy consumption of ships and reduce the exhaust emissions of ships, which will surely promote the development of green and environmentally friendly ships. Ordinary seawater heat exchangers need to be supported by a seawater circulation system, equipped with a series of pipeline accessories such as seawater filters, seawater cooling pumps, seawater pipelines, and valves. The existing seawater heat exchanger occupies the space of the ship, increases the cost and energy consumption of the ship, and brings inconvenience to the work and maintenance of the ship personnel on board.
