[0001] This utility model relates to the technical field of plate-fin heat exchangers, specifically an aluminum plate-fin heat exchanger with an installation and positioning structure. Background Technology

[0002] Aluminum plate-fin heat exchangers are widely used in many fields such as petrochemicals, air separation, aerospace, and automotive engineering due to their compact structure, high heat transfer efficiency, and lightweight design. Their core components are brazed from fins, baffles, and seals, forming complex flow channels for heat exchange between different fluids.

[0003] A search revealed a utility model patent with patent authorization announcement number CN101655321B, which discloses a high-pressure aluminum plate-fin heat exchanger, including a heat dissipation core, a head cavity, a blocking plate, and inlet and outlet flanges. The heat dissipation core is composed of a partition, inner fins, outer seals, outer fins, inner seals, and side plates. The inner channel is composed of a partition, inner fins, and inner seals, while the outer channel is composed of a partition, outer fins, and outer seals. The inner and outer channels are arranged in layers and crosswise.

[0004] In actual installation, existing plate-fin heat exchangers are typically connected to pipes and fixed to the foundation by welding simple mounting lugs or feet onto their manifolds or side plates. However, due to the inherent tolerances in the manufacturing and installation of the foundation, it is difficult to precisely align the mounting holes on the heat exchanger with the holes on the foundation's embedded parts, leading to installation difficulties. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum plate-fin heat exchanger with an installation positioning structure, which solves the problem of installation difficulties caused by installation errors in existing aluminum plate-fin heat exchangers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum plate-fin heat exchanger with an installation and positioning structure, comprising a heat exchanger body, hollow shells welded to both the left and right sides of the heat exchanger body, an installation channel steel slidably connected inside the hollow shell, a fixing block fixedly connected to the inner wall of the hollow shell, an adjusting rod mounted on the fixing block via a bearing, the adjusting rod passing through the installation channel steel and being threadedly connected to the installation channel steel, and a locking mechanism provided on the outer side of the adjusting rod.

[0007] Preferably, the mounting channel steel has multiple slots on its side, and these slots penetrate the mounting channel steel. The slots facilitate the overall installation and fixation using bolts.

[0008] Preferably, a knob is fixedly connected to the end of the adjusting rod, and the knob and the adjusting rod are an integral structure. The knob facilitates the rotation of the adjusting rod.

[0009] Preferably, a guide rod is fixedly connected to the inner wall of the hollow shell, the guide rod passing through the mounting channel steel and slidably connected to the mounting channel steel. The guide rod provides guidance for the sliding adjustment of the mounting channel steel within the hollow shell.

[0010] Preferably, a travel limit block is fixedly connected to the end of the guide rod, and the travel limit block and the guide rod are an integral structure. The travel limit block limits the travel of the mounting channel steel as it slides within the hollow shell.

[0011] Preferably, the locking mechanism includes a locking disc fixedly connected to the adjusting rod body. Two sliding rods are slidably connected inside the mounting channel steel, and the sliding rods penetrate the mounting channel steel. One end of both sliding rods is fixedly connected to a pressure ring, and the other end of both sliding rods is fixedly connected to a magnetic ring. Both the magnetic ring and the pressure ring are located outside the adjusting rod. The magnetic ring engages with the locking disc, and a locking pin is fixedly connected to the side of the magnetic ring closest to the locking disc. The locking pin is inserted into the locking disc. Through the locking mechanism, it provides a locking and anti-loosening function after the adjusting rod is adjusted. Furthermore, a ring of locking holes is provided on the locking disc for inserting the locking pin.

[0012] Preferably, a spring is fixedly connected to the side of the magnetic ring away from the locking disc, and the other end of the spring is fixedly connected to the inner wall of the hollow shell. The spring provides elastic support for the magnetic ring, the sliding rod, and the pressure ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model welds hollow shells to both sides of the heat exchanger body and incorporates adjustable mounting channel steel. It utilizes threaded adjustment rods and guide rods to achieve precise adjustment of the installation position.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 An aluminum plate-fin heat exchanger with an installation and positioning structure includes a heat exchanger body 1. Hollow shells 2 are welded to both the left and right sides of the heat exchanger body 1. An installation channel steel 3 is slidably connected inside the hollow shell 2. Multiple waist grooves 31 are formed on the sides of the installation channel steel 3, and these waist grooves 31 penetrate the installation channel steel 3. The waist grooves 31 facilitate the overall installation and fixation using bolts. A fixing block 4 is fixedly connected to the inner wall of the hollow shell 2. An adjusting rod 5 is mounted on the fixing block 4 via a bearing. The adjusting rod 5 penetrates the installation channel steel 3 and is threadedly connected to it. A knob 6 is fixedly connected to the end of the adjusting rod 5, and the knob 6 and adjusting rod 5 are an integral structure. The knob 6 facilitates the rotation of the adjusting rod 5. A guide rod 8 is fixedly connected to the inner wall of the hollow shell 2. The guide rod 8 penetrates the installation channel steel 3 and is slidably connected to it. The guide rod 8 guides the sliding adjustment of the installation channel steel 3 within the hollow shell 2. A travel limit block 9 is fixedly connected to the end of the guide rod 8, and the travel limit block 9 and the guide rod 8 are an integral structure. The travel limit block 9 limits the travel of the mounting channel steel 3 sliding inside the hollow shell 2.

[0019] Please see Figures 3-4A locking mechanism 7 is provided on the outer side of the adjusting rod 5. This locking mechanism 7 locks the adjusting rod 5 after adjustment, preventing loosening. Additionally, a locking disc 71 has a ring of locking holes for the insertion of a locking pin 75. The locking mechanism 7 includes a locking disc 71 fixedly connected to the adjusting rod 5. Two sliding rods 72 are slidably connected inside the mounting channel steel 3, and the sliding rods 72 penetrate the mounting channel steel 3. One end of each sliding rod 72 is fixedly connected to a pressure ring 73, and the other end is fixedly connected to a magnetic ring 74. Both the magnetic ring 74 and the pressure ring 73 are located on the outer side of the adjusting rod 5. The magnetic ring 74 is attracted to the locking disc 71. A locking pin 75 is fixedly connected to the side of the magnetic ring 74 closest to the locking disc 71, and the locking pin 75 is inserted into the locking disc 71. A spring 76 is fixedly connected to the side of the magnetic ring 74 furthest from the locking disc 71, and the other end of the spring 76 is fixedly connected to the inner wall of the hollow shell 2. The spring 76 provides elastic support for the magnetic ring 74, the slide bar 72, and the pressure ring 73.

[0020] The specific implementation process of this utility model is as follows: In use, firstly, the entire heat exchanger body 1 is roughly placed in the predetermined installation position, so that the mounting channel steel 3 on the left and right sides is roughly aligned with the mounting holes on the equipment foundation or support frame. Then, the operator turns the knob 6, which drives the adjusting rod 5 to rotate. The mounting channel steel 3 moves in the hollow shell 2 under the guidance of the guide rod 8, thereby precisely adjusting the position of the heat exchanger in the horizontal direction until the waist groove 31 on the mounting channel steel 3 is completely aligned with the mounting hole of the foundation. In addition, before adjusting the adjusting rod 5, the sliding rod 72 is pushed by the pressure ring 73, so that the magnetic ring 74 at the end of the sliding rod 72 and the locking pin 75 on the magnetic ring 74 are separated from the locking plate 71, which can release the limitation on the adjusting rod 5. After the adjusting rod 5 is adjusted, the pressure ring 73 is released, and the magnetic ring 74 and the locking pin 75 on the magnetic ring 74 are reset under the action of the spring 76. The magnetic ring 74 will be tightly attached to the surface of the locking plate 71 on the adjusting rod 5. Meanwhile, the locking pin 75 fixed on the magnetic ring 74 is inserted into the corresponding lock hole on the lock disc 71, effectively preventing the adjusting rod 5 from rotating unexpectedly due to vibration or other reasons, and ensuring positioning reliability.
