[0024] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0025] It should be noted that all actions involving the acquisition of signals, information, or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where the application is located, and with the authorization granted by the owner of the relevant device.

[0026] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.

[0027] Example 1:

[0028] like Figures 1-3 As shown, a reinforced hoisting structure in this embodiment includes a top cover 1 and hoisting lugs 2. The top cover 1 is provided with a plurality of hoisting lugs 2. Each hoisting lug 2 includes a connecting plate 21 and an ear portion 22. The ear portion 22 is vertically installed on the upper surface of the connecting plate 21. The hoisting lugs 2 are welded to the top cover 1 through the connecting plate 21.

[0029] The connecting plate with the lifting lugs is welded to the top plate of the condenser. This increases the number of welding points between the lugs and the top plate, and also allows the stress generated between the lugs and the condenser to be dispersed during lifting. For these two reasons, the lugs in this design will improve the connection strength and stress resistance of the lugs during the lifting and stress dispersion process of the condenser.

[0030] At least one ear 22 is welded to the upper surface of the connecting plate 21, and the ear 22 has a through hole 221 for inserting the suspension rope.

[0031] The connecting plate 21 is provided with a bevel 213, and the bevel 213 and the top cover 1 form an acute angle. This solution provides a bevel 213 on the side of the connecting plate 21, so that the bevel 213 and the top cover 1 form an acute angle structure. During the welding process, the acute angle structure can increase the welding contact area between the weld and the connecting plate and the top plate, thereby increasing the welding strength.

[0032] The top cover 1 has a conical surface, and the connecting plate 21 is an arc-shaped plate. Making the top cover conical allows the fluid to be cooled to enter the condenser through the inlet in the middle of the top cover 1 for heat exchange, providing ample heat dissipation space and increasing the heat dissipation area at the top.

[0033] Example 2:

[0034] like Figures 1-2 As shown, the connecting plate 21 in this embodiment also includes an injection hole 211 and an injection groove 212. The injection groove 212 is opened on the bottom surface of the connecting plate 21, and the opening direction of the injection groove 212 points towards the top cover 1. The injection groove 212 and the top cover 1 constitute an injection cavity. The injection hole 212 is opened inside the injection port 212, and the injection hole 212 is connected to the connecting plate 21 through.

[0035] The injection tank 212 has multiple injection holes 211, which are symmetrically distributed on the injection tank 212. The symmetrical arrangement of the injection holes 211 allows the injected metal adhesive to diffuse synchronously between the injection tank 212 and the top plate. Furthermore, the simultaneous injection of metal adhesive through multiple injection holes 211 can improve the injection efficiency and prevent the metal adhesive from cooling and solidifying during the flow process, which would affect the bonding performance.

[0036] The bottom of the groove in the injection tank 212 is provided with a mesh-like cut 213. In this solution, the bottom of the injection tank 212, which is used to inject high-temperature resistant adhesive material, is provided with a mesh-like cut 213, so that when the adhesive material fills the injection cavity, the adhesive material will form a snap-fit ​​with the mesh-like cut 213 after solidification, thereby improving the bonding performance of the adhesive material.

The reinforced side plates 3 are installed on both sides of the lug 22, and the two ends of the reinforced side plates 3 are respectively connected to the connecting plate 21 and the lug 22. The reinforced side plates 3 and the lifting lug 2 form a triangular reinforcing rib. By setting the reinforced side plates 3, the strength and rigidity of the lifting lug are improved without increasing the wall thickness of the lug 22 and the connecting plate 21, and deformation of the lug caused by uneven lifting force can also be avoided.

[0039] The reinforcing side plate 3 comprises a vertical surface 31 and an inclined surface 32, the vertical surface 31 is connected to the inclined surface 32, the vertical surface 31 abuts against the lug 22, the vertical surface 31 is provided with an auxiliary hole 311 coaxially arranged with the through hole 221 of the lug 22, the auxiliary hole 311 has the same inner diameter as the through hole 221, and the inclined surface 32 is arranged below the auxiliary hole 311. The vertical surface 31 and the inclined surface 32 of the reinforcing side plate 3 are integrally formed, so that the vertical surface 31 of the reinforcing side plate 3 is connected to the lug 22 by welding after being attached to the lug 22, and then connected to the connecting plate 21 through the inclined surface 32 arranged at an angle to the vertical surface 31, and the auxiliary hole 311 arranged on the vertical surface 31 is coaxial with the through hole 211 and has the same inner diameter, so that the lug can bear part of the stress after being lifted, and the strength and performance of the lug are improved.

[0040] Embodiment 4:

[0041] As shown in Figures 3-5 The present embodiment comprises a condensing sheet 4 installed at the lower end of the top cover 1, the condensing sheet 4 comprises a top plate 41 and a bottom plate 42 arranged oppositely, the top plate 41 and the bottom plate 42 are respectively provided with at least one material passing opening 43, and the material passing opening 43 of the top plate 41 and the material passing opening 43 of the bottom plate 42 are communicated.

[0042] The inner hole flanging at the punching position by forging and pressing process can make the hole smooth and without burrs, ensure the processing quality of the material passing opening on the surface of the condensing plate, improve the overall quality of the workpiece, and make the surface of the workpiece after sintering to form the enamel layer of the top plate and the bottom plate not cause the porcelain explosion phenomenon due to uneven coating.

[0043] The material passing opening 43 is forged and punched, and the material passing opening 43 comprises an inner hole part 431 and a flange part 432.

[0044] The material passing openings 43 between the top plate 41 and the bottom plate 42 are arranged oppositely, and the flange parts 432 of the top plate 41 and the bottom plate 42 are connected by welding.

[0045] The setting of the flange part 432 makes the connection position of the material passing openings 43 of the top plate 41 and the bottom plate 42 only welded at one position, and when the material passing opening 43 is welded, the welding gun is welded along the inside of the condensing sheet outside the flange part 432, so that the welding position of the flange part 432 is not only not arranged on the heat exchange surface of the condensing sheet 4, but also the enamel coating is not coated on the welding position.
