Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and more specifically, to a heat exchanger for cooling the circulating cooling water of large pumping stations. Background Technology

[0002] The water pump circulating cooling system is a critical component in large pumping stations, essential for ensuring normal pump operation and extending pump lifespan. The circulating cooling system typically operates as follows: cooling water is drawn from the pump's outlet, passes through a cooler (such as a radiator or heat exchanger) for heat dissipation, and then returns to the pump's inlet, forming a closed-loop cooling cycle. During this process, the cooling water absorbs and carries away the heat generated by the pump, thus maintaining the pump's operating temperature within the normal range.

[0003] Currently, a single heat exchanger cannot guarantee the circulation efficiency of cooling water in large pumping stations, so multiple heat exchangers need to be configured for cooling operations. This reduces the cooling efficiency of cooling water in large pumping stations and increases the operating cost of the coolers.

[0004] Therefore, in view of this, we have studied and improved the existing structure to provide a heat exchanger for cooling the circulating cooling water of large pumping stations, in order to achieve a more practical purpose. Utility Model Content

[0007] 2. Technical Solution

[0035] The low-level manifold 7 and the high-level manifold 10 have the same composition and arrangement direction;

[0036] An auxiliary installation structure is fixed inside the bottom header 5. The auxiliary installation structure supports the height of the low-level collection pipe 7.

[0038] Two heat exchange tubes 1 and one heat exchange tube 2 are arranged side by side with equal spacing between adjacent tubes. This increases the heat exchange area and enhances the heat exchange effect.

[0039] See Figure 3 Specifically, in the low-level manifold 7:

[0040] It includes three branch pipes 3 and two main pipes 21. The three branch pipes 3 are arranged side by side at equal intervals, and the end of each branch pipe 3 is connected to the corresponding main pipe 21.

[0041] See Figure 2 , 3 Specifically, the number of branch pipes 4 distributed on each branch pipe 3 is equal and not less than twenty.

[0042] Furthermore, by increasing the number of pipes, the heat exchange area can be increased, thereby enhancing the heat exchange effect.

[0043] See Figure 1 , Figure 2 Specifically, in the high-level manifold 10:

[0044] The main pipe 21 is installed on the wall via mounting bracket 1 8, and the branch pipe 3 is installed on the wall via mounting bracket 2 9.

[0045] The device is fixed to the wall using mounting bracket 8 and mounting bracket 9 to ensure stability during use.

[0046] See Figure 1 , Figure 2 Specifically, several T-shaped support frames 11 are welded to the bottom end of the low-position manifold 7, and the auxiliary installation structure is installed on the side of the T-shaped support frame 11.

[0047] The auxiliary installation structure includes a fully threaded stud 12, which is integrally cast with the T-shaped support frame 11;

[0048] A flat washer 14 is fitted onto the fully threaded stud 12, and a hexagonal nut 13 is threaded onto the fully threaded stud 12.

[0049] A lateral auxiliary support is formed by using a fully threaded stud 12, a hexagonal nut 13, and a flat washer 14 to improve the support stability of the low-position manifold 7.

[0053] Working principle:

[0054] When the heat exchanger is in use, the water flowing out of the pump enters the high-level manifold 10 through the manual flange shut-off valve 20, and then is distributed to heat exchange tube 1 and heat exchange tube 2 through the branch pipe 4. Cooling water flows outside heat exchange tube 1 and heat exchange tube 2, ensuring unidirectional flow of cooling water, forming heat exchange between the inside and outside of heat exchange tube 1 and heat exchange tube 2. The water that has completed the heat exchange is collected in the low-level manifold 7 and flows out to the pump, forming a circulating cooling.
