[0002] Marine coolers are widely used on oil tankers, liquefied gas carriers, container ships, bulk carriers, and engineering vessels, playing a vital role in the navigation of ships. The highly corrosive and scaling seawater operating conditions put a high test on the corrosion resistance and high efficiency of marine heat exchange equipment, while long-term continuous operation also tests the safety and stability of marine heat exchange equipment.

[0003] When ships are breaking ice in polar regions, a mixture of crushed ice and seawater can easily enter the cooler through the cooling water pipeline. Since the multiple holes in the heat exchange tubes on the tube sheet form a small-pore filter structure, and the tube sheet is thick and has a large thermal resistance, the temperature on the tube sheet is low and cannot melt the crushed ice. As a result, the crushed ice can easily accumulate on the tube sheet inside the head, causing the cooling water supply to be cut off and the cooling equipment to malfunction and stop operating, affecting the normal use of the cooler.

[0025] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0026] like Figure 1-3 As shown, an embodiment of the present invention provides an anti-blocking cooler, which includes a shell, a plurality of heat exchange tubes 8 arranged in parallel are provided inside the shell, and the shell wraps the heat exchange tubes 8 to form a heat exchange chamber, and the heat exchange chamber has a working medium inlet 9 and a working medium outlet 10 for circulating the heat exchange working medium. A water collection chamber is provided at one end of the shell, and a head tube sheet 3 is provided between the shell and the water collection chamber. The heat exchange tubes 8 pass through the head tube sheet 3 and are connected to the water collection chamber. A partition plate 1 is provided in the water collection chamber, and the partition plate 1 divides the water collection chamber into a water inlet chamber 6 and a water outlet chamber 7. The water inlet chamber 5 is provided with a water inlet 4, and the water outlet chamber 7 is provided with a water outlet 5. The partition plate 1 is located between the water inlet 4 and the water outlet 5.

[0027] It should be noted that the anti-blocking cooler provided in the embodiments of the present invention can be a dual-flow heat exchanger, in which the water inlet chamber 6 and the water outlet chamber 7 are connected, and the heat exchange pipe 8 connects the water inlet chamber 6 and the water outlet chamber 7. Seawater enters the water inlet chamber 6 through the water inlet 4, then passes through the through-holes in the head tube sheet 3 and enters the heat exchange pipe 8 for heat exchange. After the seawater in the heat exchange pipe 8 exchanges heat with the heat exchange medium in the heat exchange chamber, the seawater enters the water outlet chamber 7 through the heat exchange pipe 8 and is discharged from the heat exchanger through the water outlet 5.

[0028] In this embodiment, the partition plate 1 is set to be movable. The partition plate 1 can be opened toward the water outlet chamber 7 when a pressure difference is generated between the water inlet chamber 6 and the water outlet chamber 7. The water inlet chamber 6 and the water outlet chamber 7 are connected by the movement of the partition plate 1, so that the crushed ice accumulated in the water inlet chamber 6 is discharged into the water outlet chamber 7 and discharged to the outside of the heat exchanger through the water outlet 4, thereby solving the problem of the accumulation and blockage of crushed ice in the water inlet chamber 6 causing the cooling water supply to the heat exchange tube 8 to be cut off.

[0029] Further, if Figure 2 As shown, the partition plate 1 includes a fixed plate 101 and a movable plate 102 . The movable plate 102 is rotatably connected to the fixed plate 101 . The movable plate 102 rotates relative to the fixed plate 101 to connect or separate the water inlet chamber 6 and the water outlet chamber 7 .

[0030] Preferably, the movable plate 101 is arranged along the flow direction from the water inlet 4 to the heat exchange tube 8, that is, the movable plate 101 is arranged along the water flow direction. The end of the movable plate 102 away from the heat exchange tube 8 is rotatably connected to the fixed plate 101 by the spring hinge 2. The spring hinge 2 has a certain elastic supporting force. When the ice in the water inlet chamber 6 is not blocked, the pressure on both sides of the water inlet chamber 6 and the water outlet chamber 7 is normal. The spring hinge 2 supports the movable plate 102 and the fixed plate 101 to remain relatively still. At this time, the movable plate 102 and the fixed plate 101 are connected to form a sealed whole, separating the water inlet chamber 6 from the water outlet chamber 7; and when crushed ice enters the water inlet chamber 6 from the water inlet 4, as the crushed ice continues to accumulate in the water inlet chamber 6, the crushed ice blocks the entrance of the heat exchange tube 8, causing the water pressure in the water inlet chamber 6 to increase. The movable plate 102 opens to the side of the water outlet chamber 7 under the pressure difference between the water inlet chamber 6 and the water outlet chamber 7, so that the crushed ice is discharged into the water outlet chamber 7 through the movable plate 102 and discharged from the water outlet 5, solving the problem of crushed ice blockage in the water inlet chamber 6. After the crushed ice is discharged, the pressure difference between the water inlet chamber 6 and the water outlet chamber 7 returns to normal, the spring hinge 2 rebounds, and the movable plate 102 returns to its initial state, separating the water inlet chamber 6 from the water outlet chamber 7.

[0031] As a further improvement, Figure 3 As shown, the movable plate 102 is located in the middle of the partition plate 1, and the fixed plates 101 are symmetrically arranged on both sides of the movable plate 102. The fixed plates 101 on both sides are tilted toward the water outlet chamber 7, that is, the movable plate 102 is positioned lower than the fixed plates 101. This allows the crushed ice in the water inlet chamber 6 to be concentrated toward the movable plate 102 in the middle, facilitating discharge into the water outlet chamber 7. Furthermore, the movable plate 102 is configured as a concave plate that is recessed toward the water inlet chamber 6, further facilitating the collection of crushed ice onto the movable plate 102.

[0032] In this embodiment, the length of the movable plate 102 can be optimized, and the free end of the movable plate 102 can be extended to the position of the head tube plate 3 in the closed state. In this way, the crushed ice blocked at the head tube plate 3 can be directly discharged into the water outlet chamber 7 when the movable plate 102 is opened, thereby accelerating the discharge efficiency of the blocked crushed ice.

[0033] Preferably, the end cap tube plate 3 in this embodiment can be changed from a vertical state to an inclined setting in the direction of opening of the movable plate 102. This makes the opening larger when the movable plate 102 is opened, and the crushed ice is more easily discharged into the water outlet chamber 7, effectively increasing the efficiency of crushed ice discharge.

[0034] The anti-blocking cooler provided by the embodiment of the present invention is provided with a rotatable partition plate 1 in the water collecting chamber. When crushed ice enters the water inlet chamber 6 from the water inlet 4 and accumulates on the head tube plate 3, the partition plate 1 is rotated to an open state along the spring hinge 2 under the action of water pressure, connecting the water inlet chamber 6 with the water outlet chamber 7, and the crushed ice is discharged into the water outlet chamber 7 and discharged through the water outlet 5; after the crushed ice is discharged, the pressure difference between the water inlet chamber 6 and the water outlet chamber 7 is reduced, and the partition plate 1 is restored to a closed state under the action of the pre-tightening force of the spring hinge 2, cooling water enters the heat exchange tube 8, and the cooler function returns to normal, effectively solving the problem of ice blockage in the cooler and ensuring the normal operation of the ship during polar icebreaking navigation.

[0035] An embodiment of the present invention further provides a hull having an anti-blocking cooler as described above provided on the outside of the hull. The anti-blocking cooler effectively discharges crushed ice in the seawater to prevent blockage of the cooler, and also has the advantages described above.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
