Self-flowing outboard cooler and ship cooling system

Abstract

The embodiment of the 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 witha to-be-cooled fluid inlet and a cooled fluid outlet and comprises a first heat exchange tube bundle and a second heat exchange tube bundle which are arranged in the two directions correspondingly, and the two ends of the first heat exchange tube bundle and the two ends of the second heat exchange tube bundle are connected with end sockets correspondingly. The end sockets at the two ends of the first heat exchange tube bundle communicate with a to-be-cooled fluid inlet and a cooled fluid outlet correspondingly, and end sockets at the two ends of the second heat exchange tube bundle communicate with an end socket at one end of the first heat exchange tube bundle and a cooled fluid outlet correspondingly. A first stop valve is arranged on a communicating pipeline of the end socket of the second heat exchange tube bundle and the end socket of the first heat exchange tube bundle. According to the self-flowing type outboard cooler and the ship cooling system provided by the embodiment of the invention, the heat exchange area of the heat exchange tube bundle and the cooling water is adjusted, and the heat load requirements under different working conditions are met under the condition that the flow of the valve or the rotating speed of the water pump is not changed.

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
