Self-flowing outboard coolers and ship cooling systems

Abstract

The embodiment of the present invention relates to the technical field of ship coolers, and provides a self-flowing outboard cooler and a ship cooling system. The self-flowing outboard cooler is provided with an inlet of fluid to be cooled and an outlet of cooled fluid, which includes a first heat exchange tube bank and a second heat exchange tube bank respectively arranged along two directions, the first heat exchange tube bank and the second heat exchange tube bank The two ends of the first heat exchange tube bundle are respectively connected with heads, and the heads at both ends of the first heat exchange tube bundle are respectively connected with the inlet of the fluid to be cooled and the outlet of the cooled fluid. The head is in communication with the outlet of the cooled fluid, and a first cut-off valve is arranged on the communication pipeline between the head of the second heat exchange tube bank and the head of the first heat exchange tube bank. The self-flowing outboard cooler and the ship cooling system provided by the embodiment of the present invention meet the thermal requirements under different working conditions by adjusting the heat exchange area between the heat exchange tube bundle and the cooling water without changing the flow rate of the valve or the speed of the water pump. load demand.

Description

technical field [0001] The invention relates to the technical field of ship coolers, in particular to an artesian outboard cooler and a ship cooling system. Background technique [0002] The cooler in the traditional ship cooling system is arranged in the cabin. In order to meet the cooling demand and heat exchange efficiency, the centralized cooler is usually very large in size, occupying a large amount of effective space in the cabin, and there are leaks and blockages in the long-term operation of the seawater pipeline. and other issues; seawater pumps used to transport seawater not only consume a lot of energy, but also generate a lot of noise. In response to the above defects, some ships have begun to adopt outboard cooling technology. The centralized cooler is placed outboard, that is, between the inner and outer shells of the outboard, and the cooler is directly immersed in cooling water to cool the cooling medium of the intermediate fresh water circuit. The cooling m...

Problems solved by technology

[0004] The embodiment of the present invention provides a self-flowing outboard cooler and a ship cooling system, which is used to solve the problem that the outboard cooler in the prior art adjusts the cooling medium flow rate of the intermediate fresh water circuit through valve throttling or water pump variable speed to meet different needs. Cooling requirements, resulting in large energy losses and vibration and noise issues
