It should be noted that the drawings are very simplified and all use non-precise proportions, only to facilitate, clearly assist in the purpose of illustrating the embodiments of the present application. Figure 1 To the accompanying drawings Figure 5 The condenser of the present application is introduced.

[0035] In one embodiment, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The condenser of the present application comprises a shell 100 and a cooling pipe 200, the cooling pipe 200 is used to pass into a cooling medium to condense the steam in the shell 100.

[0036] The cooling pipe 200 has a first pipe section 210, a condensing pipe section 220 and a second pipe section 230, and the shell 100 comprises a first end plate 110, a second end plate 120, a first cylinder section 130 and a second cylinder section 140.

[0037] The first pipe section 210 is connected to and extends from the first end plate 110, and the second pipe section 230 is connected to and extends from the second end plate 120.

[0038] The first cylinder segment 130 and the first end plate 110 are integrally formed, the second cylinder segment 140 and the second end plate 120 are integrally formed, and the first cylinder segment 130 and the second cylinder segment 140 are fixedly connected by welding. The first end plate 110 is provided with a first interface pipe 150, and the second end plate 120 is provided with a second interface pipe 160.

[0039] The first cylinder segment 130 and the first end plate 110 are integrally formed, the second cylinder segment 140 and the second end plate 120 are integrally formed, and the first cylinder segment 130 and the second cylinder segment 140 are fixedly connected by welding. The first end plate 110 is provided with a first interface pipe 150, and the second end plate 120 is provided with a second interface pipe 160.

[0040] The condenser of the present application solves the problems of the structure design of the condenser shell 100 and the cooling pipe 200 by optimizing the structure design of the shell 100 and the cooling pipe 200, and improves the quality and welding efficiency of the condenser. Compared with the prior art, the condenser of the present application reduces deformation during welding, improves welding efficiency and quality, and thus improves the overall performance and production efficiency of the condenser.

[0041] Further, in one embodiment, as shown in Figure 2 The distance between the connecting weld 170 and the end of the cylinder segment is not less than 2 cm.

[0042] By setting the distance between the connecting weld 170 and the end of the cylinder segment to be not less than 2 cm, it is ensured that the clamp of the automatic welding machine can stably clamp the first cylinder segment 130 and the second cylinder segment 140 for automatic welding, ensuring the stability and strength of the welding, and further improving the overall quality of the condenser. For example, the distance between the connecting weld 170 and the end of the cylinder segment can be 3 cm, 5 cm or 6 cm, of course, it can also be other distances.

[0043] As a preferred embodiment, the connecting weld 170 can be welded by an automatic welding device to ensure the welding quality and efficiency.

[0044] Further, in one embodiment, as shown in Figure 3 and Figure 4As shown, the end face of the first end plate 110 is provided with a first mounting hole, and the first interface pipe 150 is welded and fixed with the inner wall surface of the first mounting hole. The end face of the second end plate 120 is provided with a second mounting hole, and the second interface pipe 160 is welded and fixed with the inner wall surface of the second mounting hole. The first mounting hole and the second mounting hole are arranged so that the interface pipe can be fixed on the inner wall surface of the end plate by welding.

[0045] As a preferred embodiment, as shown in the drawings, Figure 3 As shown, the first mounting hole is a first stepped hole 180, and the outer diameter of the first interface pipe 150 is adapted to the large diameter section of the first stepped hole 180 and the two are welded and fixedly connected. The second mounting hole is a second stepped hole, and the outer diameter of the second interface pipe 160 is adapted to the large diameter section of the second stepped hole and the two are welded and fixedly connected.

[0046] Specifically, the design of the stepped hole makes the outer diameter of the interface pipe adapted to the large diameter section of the hole, so as to realize the close fit of the interface pipe and the mounting hole. As a preferred embodiment, the large diameter section of the stepped hole can be designed to be equal to or slightly larger than the outer diameter of the interface pipe, so as to ensure the close fit during welding. In addition, the welding process can use automatic welding equipment to improve the welding efficiency and quality and reduce the errors caused by manual operation.

[0047] Thus, by designing the mounting hole as a stepped hole and making the outer diameter of the interface pipe adapted to the large diameter section of the stepped hole, the close fit and welded fixed connection of the interface pipe and the mounting hole are realized. The welding is relatively firm, and it is not easy to leak or not easy to weld. This design not only improves the stability and strength of the connection, but also reduces the deformation problem that may occur during welding, thereby improving the overall quality and service life of the condenser.

[0048] Further, in one of the embodiments, the first pipe section 210 penetrates the first end plate 110, and the second pipe section 230 penetrates the second end plate 120.

[0049] Specifically, the first end plate 110 is provided with a first through hole 190, and the first pipe section 210 passes through the first through hole 190. The second end plate 120 is provided with a second through hole, and the second pipe section 230 passes through the second through hole, so that the first pipe section 210 and the second pipe section 230 penetrate the first end plate 110 and the second end plate 120 respectively. This design ensures the stable fixation of the cooling pipe 200 in the shell 100. The diameters of the first through hole 190 and the second through hole can match the diameters of the first pipe section 210 and the second pipe section 230, so as to ensure that the pipe sections can smoothly pass through the through holes while maintaining the tightness of the connection. In addition, the shape of the through hole can be circular, square or other geometric shapes to adapt to different installation needs.

[0050] With this structure, the cooling pipe 200 can effectively transfer heat while avoiding displacement or damage of the pipe sections caused by vibration or external force, thereby improving the overall performance and service life of the condenser.

[0051] As a preferred embodiment, the first pipe section 210 and the second pipe section 230 can be fixed on the first end plate 110 and the second end plate 120 by welding. In addition, in order to enhance the fixing effect, a sealing ring or gasket can also be provided at the connection between the pipe section and the end plate to prevent leakage of the cooling medium. In other embodiments, the first pipe section 210 and the second pipe section 230 can also be fixed on the first end plate 110 and the second end plate 120 by threaded connection.

[0052] Further, in one of the embodiments, the condensing pipe section 220 is a coil pipe.

[0053] Specifically, the design of the coil pipe can increase the surface area of the condensing pipe section 220, thereby improving the condensing efficiency. The coil pipe structure allows the cooling medium to flow in the pipe to make more sufficient contact with the pipe wall, enhancing the heat exchange effect and helping to more effectively condense the steam into condensed water. As a preferred embodiment, the coil pipe can adopt a spiral or serpentine structure to further increase the surface area and improve the heat exchange efficiency. In addition, the material of the coil pipe can be selected to be a material with good heat conductivity, such as copper or aluminum, to ensure the maximization of the heat exchange effect.

[0054] Further, in one of the embodiments, the shell 100 and the cooling pipe 200 are both made of stainless steel.

[0055] Specifically, the selection of stainless steel material can improve the corrosion resistance and durability of the condenser. Stainless steel has good mechanical strength and chemical corrosion resistance, which enables the condenser to maintain stability and long service life in various environments. In addition, the use of stainless steel material can also solve the problem of material aging and performance degradation that the condenser may encounter in long-term use. As a preferred embodiment, the selection of stainless steel material not only enhances the mechanical strength of the condenser, but also improves its chemical corrosion resistance.

[0056] Further, in one of the embodiments, the end of the first pipe section 210 and the second pipe section 230 away from the shell 100 is respectively fixedly provided with a clamping joint 300, and the end of the first interface pipe 150 and the second interface pipe 160 away from the shell 100 is also respectively fixedly provided with a clamping joint 300.

[0057] Specifically, the card joint 300 can be implemented in various forms, for example, the card joint 300 can be fixed on the end of the first pipe section 210 or the second pipe section 230 by means of threaded connection, buckle connection or welding, etc., wherein the card joint 300 on the first pipe section 210 and the second pipe section 230 needs to be fixed after the cooling pipe 200 is installed into the shell 100. As a preferred embodiment, the card joint 300 can be designed as a sleeve with internal threads, and the quick connection and disassembly can be achieved by cooperating with the external threads of the external pipeline. Further, the card joint 300 can also be provided with a sealing ring to ensure the sealing performance of the connection to prevent the leakage of condensed water.

[0058] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
