Description

Technical Field

[0001] This utility model relates to the field of air cooler technology, specifically a sliding connection structure for air coolers. Background Technology

[0002] During operation, the heat exchange tubes of the air cooler expand and deform due to heat, and the tube heads are prone to leakage. In the existing air cooler tube box, the cap and tube sheet are bolted together. Since the cap is heavy and the weight increases when the medium enters the tube box, the bolted connection cannot effectively support the tube box and is prone to deformation. Further improvement and reinforcement are needed. Therefore, a sliding connection structure for air coolers is proposed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a sliding connection structure for air coolers. This structure solves the problem of heat exchange tube deformation caused by the inability of the fixed connection tube box to slide. It effectively protects the tube head, supports the tube box well, and facilitates disassembly. This effectively ensures the operation requirements of the detachable tube box air cooler and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sliding connection structure for an air cooler, comprising a tube box, a connecting plate, and a shell; both ends of the shell are connected to the tube box via the connecting plate, the connecting plate has folded edges, the folded edges have through holes arranged in a linear array, the folded edges are connected to the tube box via bolt and nut assemblies, the bolt and nut assemblies pass through the through holes, the connecting plate has an oblong hole, both sides of the shell are provided with side beams, the connecting plate is connected to the side beams via bolt and nut assemblies, the bolt and nut assemblies pass through the oblong hole.

[0005] Preferably, there are four connecting plates, and each end of the side beam is connected to a connecting plate. Each end of the connecting plate has a retaining edge, which corresponds to and abuts against the side edge of the side beam.

[0006] Preferably, a support pad is provided between the retaining edge and the side edge of the side beam.

[0007] Preferably, the connecting plate has four oblong holes, the length of which points towards the pipe box.

[0008] Preferably, the folded edge is further connected by two positioning blocks for positioning both sides of the tube box via bolt and nut assembly.

[0009] Preferably, the lower end of the casing is provided with a plurality of support ribs for supporting the casing.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the connecting plate is used to fix the connecting shell and the tube box. The connecting plate is provided with a baffle and a waist-shaped hole. The baffle abuts against the side of the side beam, and the waist-shaped hole allows the tube box to slide. This ensures that the tube head inside the tube box is limited in the direction of movement when it is heated and expands. This solves the problem that the tube box cannot be effectively supported by bolts and thus deforms. It effectively protects the tube head and can also support the tube box well. It is also convenient for disassembly in the future and effectively ensures the operation requirements of the detachable tube box air cooler. Attached Figure Description

[0016] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0017] Please see Figure 1-4 The present invention provides the following technical solution:

[0018] Example 1: A sliding connection structure for an air cooler includes a tube box 1, a connecting plate 2, and a shell 3; both ends of the shell 3 are connected to the tube box 1 via the connecting plate 2. The connecting plate 2 has a folded edge 2.2, and the folded edge 2.2 has through holes 2.3 arranged linearly. The folded edge 2.2 is connected to the tube box 1 via a bolt and nut assembly, which passes through the through holes 2.3. The plate body of the connecting plate 2 has an oblong hole 2.1. Both sides of the shell 3 are provided with side beams 3.1. The connecting plate 2 is connected to the side beams 3.1 via a bolt and nut assembly, which passes through the oblong hole 2.1.

[0019] It should be noted that the connecting plate 2 has four oblong holes 2.1, and the length of the oblong holes 2.1 points towards the tube box 1;

[0020] The connecting plate 2 connects and fixes the tube box 1 and the shell 3. Specifically, the plate body of the connecting plate 2 is connected to the side beam 3.1 of the shell 3 through a bolt and nut assembly and an oblong hole 2.1. The folded edge 2.2 of the connecting plate 2 is connected to the tube box 1 through a bolt and nut assembly and a through hole 2.3, which effectively supports the tube box 1 and effectively protects the tube head, ensuring the operation requirements of the detachable tube box air cooler. This solves many drawbacks of traditional bolt-connected systems. Moreover, the oblong hole 2.1 connection limits the movement direction of the tube box 1, solving the problem of tube box deformation caused by the inability to effectively support the tube box when connected only by bolts.

[0021] Example 2: Unlike Example 1, there are four connecting plates 2. Both ends of the side beam 3.1 are connected to the connecting plates 2. Both ends of the connecting plates 2 have flanges 2.4, which abut against the sides of the side beam 3.1. Supporting pads are also provided between the flanges 2.4 and the sides of the side beam 3.1. The connecting plates 2 are supported and fixed by the abutting between the flanges 2.4 and the sides of the side beam 3.1. That is, the connecting plates 2 are inserted into the side beam 3.1, which can well support the pipe box 1, and the flanges 2.4 are fixed by the supporting pads.

[0022] Example 3: Unlike Example 1, the folded edge 2.2 is also connected by bolt and nut assembly to two positioning blocks 4 on both sides of the positioning box 1. The positioning blocks 4 are used to position the box 1 and also support the box 1.

[0023] In addition, multiple support ribs 3.2 for supporting the pipe box 1 are provided at the lower end of the housing 3, which further effectively support the pipe box 1.

[0024] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents in the content of this utility model.
