Description

Technical Field

[0001] The utility model relates to the technical field of plate-fin heat exchangers, in particular to a plate-fin heat exchanger which is easy to position and install. Background Art

[0002] Plate-fin heat exchangers are usually composed of baffles, fins, seals, and guide vanes. Fins, guide vanes, and seals are placed between two adjacent baffles to form a sandwich called a channel. Such sandwiches are stacked according to different fluid flow patterns and brazed into a whole to form a plate bundle, which is the core of the plate-fin heat exchanger.

[0003] Existing Chinese patent CN216717099U discloses a plate-fin heat exchanger that is easy to position and install. The plate-fin heat exchanger that is easy to position and install drives a bidirectional threaded rod to rotate by turning a knob, so that two clamping rods approach each other, thereby clamping the seat plate and fixing the seat plate. The seat plate is clamped by two clamping blocks, thereby improving the stability of the seat plate and achieving fixation of the plate-fin heat exchanger body.

[0004] However, when installing the plate-fin heat exchanger, it is often installed near the supporting equipment according to the use environment. The use of mounting racks with multiple structures cannot cope with various installation environments. Moreover, after the plate-fin heat exchanger is installed on the mounting rack, the mounting rack still needs to be fixed. Compared with directly installing the plate-fin heat exchanger on the supporting equipment, this installation method is not convenient. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-Figure 5 The utility model provides a technical solution: a plate-fin heat exchanger that is easy to position and install, including a plate-fin heat exchanger body 1, a welded bottom plate 102 fixedly installed at the bottom of the plate-fin heat exchanger body 1, a water inlet pipe 103 and a water outlet pipe 104 connected to the right side of the plate-fin heat exchanger body 1, and mounting mechanisms 2 are provided at the four corners of the welded bottom plate 102;

[0024] The mounting mechanism 2 includes a long hole slot 201, a bolt clamping block 202, and a mounting slot 206. The long hole slot 201 is opened on the top of the welding base plate 102. The length of the long hole slot 201 is four times its width. A bolt clamping block 202 is slidingly provided inside the long hole slot 201. There are two bolt clamping blocks 202 in one long hole slot 201. The length of the bolt clamping block 202 is consistent with the width of the long hole slot 201. The outer wall of the bolt clamping block 202 is provided with an integrally formed protrusion, and the protrusion is slidably provided in the groove on the inner wall of the long hole slot 201. The mounting groove 206 is provided at the top of the welding base plate 102. A spring 207 is fixedly installed on the inner wall of the bottom of the mounting groove 206. A connecting plate 205 is fixedly installed on the top of the spring 207. A bevel card plate 204 is fixedly installed on the bottom of the connecting plate 205. An inclined groove 203 is provided on the outer wall of the bolt pressing block 202. The bevel card plate 204 is slidably provided in the inclined groove 203. The bevel card plate 204 is larger at the top and smaller at the bottom. A through hole 208 is provided at the center of the connecting plate 205. The diameter of the through hole 208 is twice the width of the long hole groove 201. The long hole groove 201 is provided. The bolts for installation pass through the long hole slot 201. Since the length of the long hole slot 201 is twice the width of the long hole slot 201, there is sufficient space for the bolts for installation to pass through the long hole slot 201, which is convenient for the user to pass the bolts through the long hole slot 201. After the bolts pass through the long hole slot 201, the hexagonal nut is tightened to press the connecting plate 205 downward, so that the connecting plate 205 moves downward, thereby driving the inclined clamping plate 204 to move downward, so that the inclined clamping plate 204 pushes the bolt clamping block 202 to move toward the bolt, compressing the bolt so that the tightening After the hexagonal nut is tightened, the bottom plate 102 is welded to the installation position, and the problem of left and right shaking will not occur. During installation, this design only needs to be fixed with the bolt and the hexagonal nut. Compared with the threaded hole that just matches the bolt, the long hole groove 201 with interference setting can also facilitate the bolt to pass through the long hole groove 201. A spring 207 is provided to lift the connecting plate 205, thereby ensuring that during the insertion of the bolt, the inclined clamping plate 204 will not move downward to push the bolt clamping block 202 to move toward the bolt, thereby preventing the bolt clamping block 202 from hindering the insertion of the bolt;

[0025] The inclined clamping plate 204 is made of magnet material, and the bolt pressing block 202 is made of iron. The magnetic attraction between the inclined clamping plate 204 and the bolt pressing block 202 is used to prevent the bolt pressing block 202 from sliding freely during the insertion of the bolt, thereby preventing the bolt pressing block 202 from obstructing the insertion of the bolt. The side surface of the bolt pressing block 202 facing the center of the long hole groove 201 is a concave arc surface, so that when the bolt pressing block 202 presses the bolt, the contact surface of the bolt pressing block 202 and the bolt can fully contact, thereby ensuring the tightening effect of the bolt;

[0026] A limit frame 6 is fixedly installed on the top of the welding base plate 102. The inner diameter of the limit frame 6 is consistent with the outer diameter of the connecting plate 205. The limit frame 6 is located below the connecting plate 205. When the connecting plate 205 is pressed down to the lowest position by the hexagonal nut, the connecting plate 205 just falls into the limit frame 6, which is used to remind the user that the bolt is fixed.

[0027] A guide hole 5 is formed at the bottom of the mounting groove 206. A guide rod 7 is fixedly mounted at the bottom of the connecting plate 205. The bottom end of the guide rod 7 movably extends into the guide hole 5. The guide hole 5 and the guide rod 7 are provided to guide the connecting plate 205 so that the connecting plate 205 can only move up and down relative to the welding base plate 102.

[0028] A shock-absorbing pad 3 is fixedly installed at the bottom of the welding base plate 102. An avoidance groove 4 is opened at the bottom of the shock-absorbing pad 3. The avoidance groove 4 is opposite to the long hole groove 201, and the length and width of the avoidance groove 4 are consistent with the length and width of the long hole groove 201. The shock-absorbing pad 3 is used to form a buffer layer between the welding base plate 102 and the installation part to ensure the installation stability of the welding base plate 102. The avoidance groove 4 corresponding to the long hole groove 201 is provided to prevent the shock-absorbing pad 3 from interfering with the insertion of the bolt;

[0029] There are four springs 207 and four guide rods 7 at the bottom of the connecting plate 205, and they are respectively located at the four corners of the bottom of the connecting plate 205. Multiple limiters and guides are used to ensure that the connecting plate 205 does not tilt when moving up and down.

[0030] Working principle: When in use, first install the four bolts for installation on the installation part, which can be done by welding or screwing into the threaded holes, and then drop the entire plate-fin heat exchanger on the installation part. During the dropping process, you only need to ensure that the bolts can be inserted into the long hole slot 201. There is no need to align the center of the plate-fin heat exchanger with the center of the installation part. After the bolt passes through the long hole slot 201, screw the hexagonal nut from the top of the bolt, and then rotate the hexagonal nut to move the hexagonal nut downward, and then press down the connecting plate 205, so that the connecting plate 205 moves downward and drives the inclined clamping plate 204 to move downward. The downward movement of the inclined clamping plate 204 pushes the bolt clamping block 202 toward the bolt until the left and right bolt clamping blocks 202 are tightly pressed on the bolt to fix the bolt. During the tightening process, the center of the plate-fin heat exchanger will automatically align with the center of the installation part. Tighten the hexagonal nuts on the four bolts to complete the installation of the plate-fin heat exchanger. Because it is installed with bolts and nuts, it can adapt to a variety of installation environments.

[0031] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
