Description

Technical Field

[0001] This application relates to the technical field of foundation pit support and protection, and in particular to a high-efficiency water-cooled condenser. Background Technology

[0002] The condenser is the core heat exchange component in refrigeration, air conditioning and heat pump systems. Its core function is to convert high-temperature and high-pressure gaseous refrigerant into liquid through heat exchange, while releasing the heat generated by the system to the external environment.

[0003] Traditional condensers mostly employ straight tube or simple bend tube designs, with heat exchange efficiency limited by the finite surface area and unidirectional water flow path. In recent years, with increasing demands for energy conservation, higher requirements have been placed on the heat exchange efficiency and durability of condensers, but existing technologies still have significant shortcomings in terms of material selection and structural optimization.

[0004] Existing condensers typically employ two design schemes: one is the straight-tube condenser, which has a simple structure and low cost, but low heat exchange efficiency; the other is the baffle plate condenser, which improves efficiency by increasing water flow disturbance. In addition, some high-end equipment uses copper tube and aluminum fin structure to improve heat dissipation performance. Existing technologies generally suffer from low surface area utilization, so it is necessary to propose a high-efficiency water-cooled condenser to solve the above problems. Utility Model Content

[0005] To address the problem of low surface area utilization in existing water-cooled condensers, this application provides a high-efficiency water-cooled condenser.

[0006] This application provides a high-efficiency water-cooled condenser, which adopts the following technical solution: A high-efficiency water-cooled condenser includes a cylinder. A first flange is fixedly installed on the left side of the cylinder, and a first water inlet pipe is fixedly connected to the left side of the first flange. A second flange is fixedly installed on the right side of the cylinder, and a first drain pipe is fixedly connected to the right side of the second flange. Support frames are fixedly installed at the top and bottom of the cylinder. A condenser tube is fixedly connected inside the cylinder, and the condenser tube adopts a spiral coil design.

[0007] By adopting a spiral coil design for the condenser tube instead of the direct-flow tube design used in existing technologies, the surface area of ​​the condenser tube can be increased, thereby expanding the contact area between the condenser tube and the condensate, thus improving the condensation effect of the refrigerant on the cooling water.

[0008] A further improvement of the technical solution of this application is that: a water inlet is provided at the top of the condenser tube near the right side, a drain outlet is provided at the top of the condenser tube near the left side, a second water inlet pipe is fixedly installed at the top of the cylinder, the second water inlet pipe is connected to the water inlet, and a second drain pipe is fixedly connected to the top of the cylinder on the left side of the second water inlet pipe, the second drain pipe is connected to the drain outlet.

[0009] By adopting the above technical solution, the second water inlet pipe and the second water outlet pipe, as well as the first water inlet pipe and the first water outlet pipe, are respectively set at designated positions, so that the refrigerant flows from right to left and the cooling water flows from left to right, and the two flow in opposite directions, so that the water flow path is counter-current. This counter-current arrangement can ensure that a relatively uniform and large logarithmic mean temperature difference is maintained on the entire heat exchange surface, overcoming the shortcomings of uneven temperature difference in traditional cross-flow or mixed flow paths, thereby improving heat exchange efficiency.

[0010] A further improvement to the technical solution of this application is that the cylinder is made of stainless steel sealing material.

[0011] By adopting the above technical solution, the cylinder is set as a stainless steel sealing cover, providing a sealed environment that is isolated from the outside air for the internal condenser tube. This effectively prevents the anti-corrosion zinc coating that may be used on the surface of the coil from coming into contact with humid air, fundamentally eliminating the oxidation process of zinc powder, extending the service life of the core components, and maintaining stable heat exchange performance.

[0012] A further improvement of the technical solution of this application is that a first flow equalization plate is fixedly installed inside the cylinder on the left side of the condenser tube, and a number of third through holes are opened on the surface of the first flow equalization plate.

[0013] By adopting the above technical solution, the flow direction of the cooling water can be guided and limited before it approaches the surface of the condenser tube through the cooperation between the first flow equalization plate and the third through hole. This ensures that the cooling water can pass through the entire outer surface of the condenser tube evenly, eliminates the flow dead zone, and maximizes the utilization of all heat exchange areas, thereby further improving the condensation effect.

[0014] A further improvement of the technical solution of this application is that a second flow equalization plate is fixedly installed inside the cylinder surrounding the condenser tube, and the surface of the second flow equalization plate is provided with a number of second through holes.

[0015] By adopting the above technical solution, the flow direction of the cooling water can be further guided and limited during the process of the cooling water flowing through the surface of the condenser tube through the cooperation between the second flow equalizing plate and the second through hole. This ensures that the cooling water can pass through the entire outer surface of the condenser tube evenly, eliminates the flow dead zone, and maximizes the utilization of all heat exchange areas, thereby further improving the condensation effect.

[0016] A further improvement of the technical solution of this application is that a third flow equalization plate is fixedly installed inside the cylinder on the right side of the condenser tube, and the surface of the third flow equalization plate is provided with several first through holes.

[0017] By adopting the above technical solution, the flow direction of the cooling water can be guided and limited after the cooling water leaves the surface of the condenser tube through the cooperation between the third flow equalizer and the first through hole. This ensures that the cooling water can pass through the entire outer surface of the condenser tube evenly, eliminates the flow dead zone, and maximizes the utilization of all heat exchange areas, thereby further improving the condensation effect.

[0018] A further improvement to the technical solution of this application is that a guide plate is fixedly installed inside the cylinder on the left side of the first flow equalization plate, and the guide plate is arranged in an arc shape.

[0019] By adopting the above technical solution, the flow direction of the cooling water can be guided and limited before it approaches the surface of the condenser tube by installing an arc-shaped guide plate. This guides the cooling water to the outside of the condenser tube, reducing the impact of the water flow on the surface of the condenser tube and thus protecting the condenser tube.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. This application provides a high-efficiency water-cooled condenser. By adopting a spiral coil design for the condenser tube, the surface area of ​​the condenser tube can be increased, thereby expanding the contact area between the condenser tube and the condensate and improving the condensation effect of the refrigerant on the cooling water.

[0021] 2. This application provides a high-efficiency water-cooled condenser. By reversing the second water inlet pipe and the second water outlet pipe, as well as the first water inlet pipe and the first water outlet pipe, the refrigerant flows from right to left and the cooling water flows from left to right. This allows the water flow path to be set in a counter-current manner, ensuring a relatively uniform and large logarithmic average temperature difference across the entire heat exchange surface. This overcomes the shortcomings of uneven temperature difference in traditional cross-flow or mixed flow paths, thereby improving heat exchange efficiency.

[0022] 3. This application provides a high-efficiency water-cooled condenser. By setting the cylinder as a stainless steel sealing cover, it provides a sealed environment that is isolated from the outside air for the internal condenser tubes. This can prevent the anti-corrosion zinc coating that may be used on the surface of the coil from coming into contact with humid air, fundamentally eliminating the oxidation process of zinc powder, thereby extending the service life of the core components and maintaining stable heat exchange performance.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] Example 1 See Figure 1 , Figure 2 and Figure 3 This application provides a high-efficiency water-cooled condenser, including a cylinder 1. A first flange 2 is fixedly installed on the left side of the cylinder 1, and a first water inlet pipe 3 is fixedly connected to the left side of the first flange 2. A second flange 4 is fixedly installed on the right side of the cylinder 1, and a first drain pipe 5 is fixedly connected to the right side of the second flange 4. Support frames 6 are fixedly installed on the top and bottom of the cylinder 1. A condenser pipe 7 is fixedly connected inside the cylinder 1. The condenser pipe 7 adopts a spiral coil design.

[0027] In this embodiment, by adopting a spiral coil design for the condenser tube 7 instead of the direct-flow tube design used in the prior art, the surface area of ​​the condenser tube 7 can be increased, thereby expanding the contact area between the condenser tube 7 and the condensate, thus improving the condensation effect of the refrigerant on the cooling water.

[0028] Example 2 See Figure 1 , Figure 2 and Figure 3 Based on Embodiment 1, this application provides a technical solution: Preferably, the top of the condenser tube 7 near the right side is provided with a water inlet 14, the top of the condenser tube 7 near the left side is provided with a drain outlet 15, the top of the cylinder 1 is fixedly installed with a second water inlet pipe 8, the second water inlet pipe 8 and the water inlet 14 are interconnected, the top of the cylinder 1 to the left of the second water inlet pipe 8 is fixedly connected with a second drain pipe 9, the second drain pipe 9 and the drain outlet 15 are interconnected; the cylinder 1 is made of stainless steel sealing cover material.

[0029] In this embodiment, by setting the second water inlet pipe 8 and the second drain pipe 9, as well as the first water inlet pipe 3 and the first drain pipe 5, at designated positions, the refrigerant flows from right to left, and the cooling water flows from left to right, with the two flowing in opposite directions. This creates a counter-current flow path, which ensures a relatively uniform and large logarithmic mean temperature difference across the entire heat exchange surface. This overcomes the disadvantages of uneven temperature differences in traditional cross-flow or mixed flow paths, thereby improving heat exchange efficiency. By setting the cylinder 1 as a stainless steel sealing cover, a sealed environment isolated from the outside air is provided for the internal condenser 7. This effectively prevents the anti-corrosion zinc coating that may be used on the coil surface from contacting humid air, fundamentally eliminating the oxidation process of zinc powder, extending the service life of core components, and maintaining stable heat exchange performance.

[0030] Example 3 See Figure 2 , Figure 4 and Figure 5 Based on Embodiment 2, this application provides a technical solution: Preferably, a first flow equalization plate 11 is fixedly installed inside the cylinder 1 on the left side of the condenser tube 7, and a plurality of third through holes 18 are opened on the surface of the first flow equalization plate 11; a second flow equalization plate 12 is fixedly installed inside the cylinder 1 surrounding the condenser tube 7, and a plurality of second through holes 17 are opened on the surface of the second flow equalization plate 12; a third flow equalization plate 13 is fixedly installed inside the cylinder 1 on the right side of the condenser tube 7, and a plurality of first through holes 16 are opened on the surface of the third flow equalization plate 13; a guide plate 10 is fixedly installed inside the cylinder 1 on the left side of the first flow equalization plate 11, and the guide plate 10 is arranged in an arc shape.

[0031] In this embodiment, the interaction between the first flow equalization plate 11 and the third through hole 18 guides and limits the flow of cooling water before it approaches the surface of the condenser tube 7. The interaction between the second flow equalization plate 12 and the second through hole 17 further guides and limits the flow of cooling water as it flows over the surface of the condenser tube 7. The interaction between the third flow equalization plate 13 and the first through hole 16 guides and limits the flow of cooling water after it leaves the surface of the condenser tube 7. This ensures that the cooling water can pass through the entire outer surface of the condenser tube 7 evenly, eliminating dead zones and maximizing the utilization of all heat exchange areas, thereby further improving the condensation effect. By installing the arc-shaped guide plate 10, the flow of cooling water is guided and limited before it approaches the surface of the condenser tube 7, directing the cooling water to the outside of the condenser tube 7 and reducing the impact of the water flow on the surface of the condenser tube 7, thus protecting the condenser tube 7.

[0032] The working principle of this high-efficiency water-cooled condenser is explained in detail below.

[0033] like Figures 1-5As shown, the operator connects the first inlet pipe 3 and the first drain pipe 5 to the cooling water pipeline, and connects the second inlet pipe 8 and the second drain pipe 9 to the refrigerant pipeline. This allows the refrigerant to enter the interior of the condenser pipe 7 through the second inlet pipe 8 and flow out through the second drain pipe 9. At the same time, the cooling water enters the interior of the cylinder 1 from the first inlet pipe 3 and flows to the right. Guided by the guide plate 10, the first flow equalization plate 11, the second flow equalization plate 12 and the third flow equalization plate 13, the cooling water finally flows out through the first drain pipe 5, thus completing the condensation process of the cooling water.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
