Problems solved by technology

[0003] Existing outboard coolers are commonly used for cooling marine generators. However, the existing outboard coolers often have the following defects during use. First, the existing outboard coolers are often made of nickel white copper tubes Or aluminum brass pipes, however, the corrosion ability of seawater is much stronger than that of fresh water, so this copper pipe will also have the problem of corrosion damage after a period of use; secondly, the existing outboard cooler has a high temperature, which is easy to cause Many heat-resistant organisms are adsorbed on the outer wall of the cooler, which accelerates the corrosion of the cooler and is not conducive to the heat dissipation of the cooler

[0025] Embodiment one, with reference to Figure 1-4 , a seawater corrosion-resistant titanium tube outboard cooler, including an end cover 1 and a tube plate 10 fixedly connected to the bottom of the end cover 1, the inner cavity of the tube plate 10 is provided with a cooling tube 3, and the two sides of the upper end surface of the end cover 1 are connected respectively There are two flanges 2, and the two flanges 2 are connected with the cooling pipe 3, the center of the lower end surface of the end cover 1 is provided with a limit groove 9, and the inner cavity of the limit groove 9 is slidingly connected with a rotating sleeve 16, and the rotating sleeve Both sides of 16 are fixedly connected with an inner housing 12, and the inner cavity of the inner housing 12 is connected with a first transmission gear plate 13 and a second transmission gear plate 15 through a rotating shaft, and the inner cavity of the inner housing 12 is provided with a first gear The winch 11 is co...

Embodiment 2

[0026] Embodiment two, refer to Figure 1-4 , the second transmission gear plate 15 is engaged with the threaded rod 8 and the first gear capstan 11 respectively, and the first transmission gear plate 13 is meshed with the first gear capstan 11 and the second gear capstan 14 respectively, and both ends of the threaded rod 8 run through At the left and right ends of the tube plate 10, the side walls at the two top ends of the threaded rod 8 are provided with helical blades 7, so that the helical blades 7 can obtain the rotation effect when the hull moves, so that the threaded rod 8 drives the first gear winch 11 to the first gear. The gear capstan 14 rotates and removes impurities for the cooling pipe 3 .

Embodiment 3

[0027] Embodiment three, refer to Figure 1-4 , the upper end surface of the rotating sleeve 16 is provided with a control rod 4, and the control rod 4 is fixedly connected with the end cover 1 through a nut, and there are a plurality of cooling pipes 3, and the upper end surfaces of the plurality of cooling pipes 3 are connected with a communication chamber 5, and communicated with each other. The cavity 5 is fixedly connected with the end cover 1, the inner and outer walls of the first gear winch 11 and the second gear winch 14 are in the form of threaded tooth grooves, and the inner and outer walls of the first gear winch 11 and the second gear winch 14 are connected with the cooling pipe 3 The outer wall is bonded, and there are fixing parts 6 on both sides of the upper end surface of the end cover 1. The cooling pipe 3 is made of titanium alloy, so that the corrosion resistance of the cooling pipe 3 is increased, and the speed of the cooling pipe 3 being damaged by corrosi...

Abstract

The invention discloses a seawater corrosion-resistant titanium tube outboard cooler, which comprises an end cover and a tube plate fixedly connected to the bottom of the end cover, the inner cavity of the tube plate is provided with a cooling pipe, and the two sides of the upper end surface of the end cover are respectively There are two flanges in communication, and the two flanges are connected with the cooling pipe. The center of the lower end surface of the end cover is provided with a limiting groove, and the inner cavity of the limiting groove is slidably connected with a rotating sleeve. The two sides of the rotating sleeve Both are fixedly connected with an inner casing, the inner casing is slidably connected with the cooling pipe, and the cooling pipe is respectively rotatably connected with the first gear capstan and the second gear capstan. In the present invention, the titanium tube structure is adopted to realize that the tube wall of the titanium tube is thinner than the copper tube, further reducing the weight of the cooling tube, and a rotating impurity removal structure is adopted to realize friction scraping and cleaning of the outer wall of the cooling tube. A two-way anti-helical structure is adopted to achieve an enhanced scraping effect on impurities on the outer wall of the cooling tube.

Description

technical field [0001] The invention belongs to the technical field of outboard coolers, in particular to a seawater corrosion-resistant titanium tube outboard cooler. Background technique [0002] Cooler is a kind of heat exchange equipment, used to cool fluid, usually use water as coolant to remove heat, widely used for cooling the main and auxiliary equipment of ships as cooling. [0003] Existing outboard coolers are commonly used for cooling marine generators. However, the existing outboard coolers often have the following defects during use. First, the existing outboard coolers are often made of nickel white copper tubes Or aluminum brass pipes, however, the corrosion ability of seawater is much stronger than that of fresh water, so this copper pipe will also have the problem of corrosion damage after a period of use; secondly, the existing outboard cooler has a high temperature, which is easy to cause Many heat-resistant organisms are adsorbed on the outer wall of th...
