Description

Technical Field

[0001] This utility model relates to the field of water replenishment tank technology, and in particular to an air-cooled water replenishment tank. Background Technology

[0002] The safety and stability of a nuclear power plant are among the most critical factors in its operation. The core makeup water tank is a crucial safety device for ensuring safe operation under extreme conditions. Its primary function is to store cooling water (such as boronic acid). When the core overheats, the core makeup water tank supplies boronic acid to the core, inhibiting the continuous rise in core temperature and preventing overheating. As a key piece of equipment in a nuclear power plant, besides the effective heat dissipation of boronic acid into the core, the core makeup water tank also generates heat even when boronic acid is not being applied. With the development of nuclear power technology, the requirements for the heat dissipation efficiency of the core makeup water tank are becoming increasingly stringent.

[0003] Currently, to address the insufficient heat dissipation efficiency of reactor core makeup water tanks, the main measures taken include increasing the surface area of ​​the tank, using high thermal conductivity materials, and utilizing natural convection. For example, increasing the surface area of ​​the tank can improve heat transfer efficiency; using high thermal conductivity materials, such as stainless steel, can accelerate heat conduction; and utilizing natural convection allows heat to be carried away by the natural flow of air or water. However, these methods have certain limitations in terms of heat dissipation efficiency and speed. Although existing technologies have improved the heat dissipation efficiency of reactor core makeup water tanks to some extent, some problems and shortcomings still exist. First, increasing the surface area of ​​the tank requires more space, which is not suitable for nuclear power plants with limited space. Second, although high thermal conductivity materials can accelerate heat conduction, their performance may degrade under high-temperature environments, affecting long-term stability. In addition, natural convection has low heat dissipation efficiency, especially under high-temperature environments, where the flow rate of air or water is insufficient to quickly remove large amounts of heat.

[0031] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] like Figures 1 to 4 As shown, an embodiment of the present invention provides an air-cooled water supply tank, including a fan assembly 1, a first fin assembly 2, a water supply tank 3 with a water storage space 31, and a shell 4 with an internal space 41; the water supply tank 3 is installed in the internal space 41; the fan assembly 1 is installed on the top of the water supply tank 3 for blowing cooling air into the internal space 41; the bottom of the shell 4 is provided with an air outlet group 42 communicating with the internal space 41;

[0033] The first fin assembly 2 is installed on the outer wall of the water tank 3, and the first fin assembly 2 is arranged opposite to the fan assembly 1.

[0034] The fan assembly 1 includes multiple fans, and the number of fans can be set according to actual needs; the first fin assembly 2 is made of a material with good thermal conductivity.

[0035] Specifically, during use, the water tank 3 transfers heat to the internal space 41 via thermal conduction. The heat generally rises, resulting in a higher temperature at the top than at the bottom of the internal space 41. The fan assembly 1 blows outside air into the internal space 41 and returns it to the outside environment through the air outlet group 42 at the bottom of the outer casing 4. As the air flows through the internal space 41, it carries away the heat within, keeping the water tank 3 in a low-temperature environment. This lowers the temperature of the cooling water inside the water tank 3 and improves the cooling efficiency of the air-cooled water tank. Furthermore, a first fin assembly 2 is installed on the outer wall of the water tank 3. The first fin assembly 2 increases the contact area between the water tank 3 and the air, and the fan assembly 1 blows air towards the first fin assembly 2, increasing its air-cooling efficiency and further improving the overall cooling efficiency of the air-cooled water tank.

[0036] In one embodiment, such as Figure 4 and Figure 5 As shown, the first fin assembly 2 includes a first heat dissipation fin 21 and a heat-conducting box 22 with a receiving space 221. The first heat dissipation fin 21 is installed in the receiving space 221, and the heat-conducting box 22 is attached to the outer wall of the water supply tank 3.

[0037] The heat-conducting box 22 is made of a material with good thermal conductivity, such as aluminum or copper; the first heat dissipation fin 21 is in a bent shape.

[0038] Specifically, the heat-conducting box 22 is attached to the inner wall of the water supply tank 3. The water supply tank 3 can transfer heat to the heat-conducting box 22 through heat conduction. The heat-conducting box 22 then transfers the heat to the internal space 41 through the first heat dissipation fins 21. The air blown in by the fan assembly 1 then carries away the heat.

[0039] In this embodiment, the first fin assembly 2 has a simple structure and is easy to assemble.

[0040] In one embodiment, such as Figures 1 to 3 As shown, the air-cooled water supply tank also includes a second fin assembly 5, which is installed on the inner wall of the water supply tank 3.

[0041] The second fin assembly 5 is made of a material with good thermal conductivity and is attached to the inner wall of the water storage space 31.

[0042] In this embodiment, the second fin assembly 5 increases the contact area between the cooling water in the water storage space 31 and the water replenishment tank 3, so that the cooling tank in the water storage space 31 can more easily transfer heat to the water replenishment tank 3. The water replenishment tank 3 transfers the heat from the first fin assembly 2 to the internal space 41. Finally, the air blown in by the fan assembly 1 drives the external environment. The design of the second fin assembly 5 further improves the cooling efficiency of the air-cooled water replenishment tank.

[0043] In one embodiment, such as Figure 6 As shown, the second fin assembly 5 includes a support plate 51 and a second heat dissipation fin 52 mounted on the support plate 51. The support plate 51 is mounted on the inner wall of the water supply tank 3.

[0044] The support plate 51 is made of a material with good thermal conductivity, and the second heat dissipation fin 52 is in a bent shape.

[0045] Specifically, the second heat dissipation fin 52 has a large contact area with the cooling water in the water storage space 31, so that the heat of the cooling water in the water storage space 31 can be more easily transferred to the water replenishment tank 3 through the second fin assembly 5, and then transferred to the internal space 41 through the water replenishment tank 3. In this embodiment, the second fin assembly 5 has a simple structure and low manufacturing cost.

[0046] In one embodiment, such as Figure 1 As shown, the air-cooled water supply tank also includes an air guide assembly 6, which includes a base plate 61 and a plurality of inclined plates 62 spaced apart on the base plate 61. The base plate 61 is installed on the inner wall of the outer shell 4, and the inclined plates 62 are used to guide the cooling air to the first fin assembly 2.

[0047] The number of inclined plates 62 can be set according to actual needs. The inclined plates 62 are arranged vertically at intervals on the support plate 51, and the inclined plates 62 are inclined toward the first wing plate assembly 2. The inclined plates 62 and the support plate 51 are integrally formed parts.

[0048] Specifically, when the air blown out by the fan assembly 1 is directed toward the inner wall of the housing 4, the inclined plate 62 can guide the air to the first fin assembly 2, further improving the heat exchange efficiency of the first fin assembly 2 and also further improving the cooling efficiency of the air-cooled water supply tank.

[0049] In one embodiment, such as Figures 2 to 4 As shown, the first fin assembly 2 is installed on each of the four outer side walls of the water replenishment tank 3; the air guide assembly 6 is installed on each of the four inner walls of the outer shell 4, and the air guide assembly 6 is arranged in a one-to-one correspondence with the first fin assembly 2.

[0050] Each of the first fin assembly 2 has an air guide assembly 6 on its side, and each of the water supply tanks 3 has a first fin assembly 2 attached to its side, which further improves the heat exchange efficiency of the first fin assembly 2 and also further improves the cooling efficiency of the air-cooled water supply tank.

[0052] The fan assembly 1 includes a plurality of fans spaced apart on the housing 43.

[0053] The cover 43 can be detachably installed on the top of the housing 44 using fasteners 45 such as screws and bolts.

[0054] In this embodiment, after the cover 43 is removed from the housing 44, the fan assembly 1 is integrated onto the cover 43, thereby facilitating the inspection and disassembly of the fan assembly 1.

[0055] In one embodiment, such as Figure 1 As shown, the cover 43 is provided with a first annular outward flange 431, and the first annular outward flange 431 is provided with a plurality of first through holes spaced apart; the housing 44 is provided with a second annular outward flange 441, and the second annular outward flange 441 is provided with a plurality of second through holes spaced apart.

[0056] The outer casing 4 also includes a plurality of fasteners 45; the first annular outer flange 431 fits into the second annular outer flange 441, and the fasteners 45 are inserted one-to-one into the first through hole and the second through hole.

[0057] The first annular outward flange 431 surrounds the bottom of the shell cover 43, and the second annular outward flange 441 surrounds the top of the shell 44; the fasteners 45 include, but are not limited to, screws, bolts, etc.; the number of fasteners 45 can be set according to actual needs.

[0058] In this embodiment, the design of the first annular outward flange 431 and the second annular outward flange 441 improves the ease of disassembly and assembly between the cover 43 and the housing 44.

[0062] One end of the inlet pipe 7 is located outside the air-cooled water supply tank, and the other end of the inlet pipe 7 passes through the fifth through hole and the third through hole in sequence to enter the water storage space 31, so that external water pumps, etc. can input cooling water into the water storage space 31 through the inlet pipe 7; one end of the outlet pipe 8 is located in the water storage space 31, and the other end of the outlet pipe 8 passes through the sixth through hole and the fourth through hole in sequence to extend into the outside of the air-cooled water supply tank, so that the cooling water in the water storage space 31 can be output through the outlet pipe 8.
