Description

Technical Field

[0001] The present application relates to the technical field of heat exchangers, and in particular to a hot air energy fin heat exchanger. Background Art

[0002] Hot air fin heat exchanger generally refers to a device used to heat or cool air, also known as a heat exchanger. It usually consists of a series of metal fins that can effectively conduct heat. Hot air fins heat or cool air by passing a coolant (such as water or refrigerant) through the fins, thereby absorbing or releasing heat. This device is widely used in many fields, such as air conditioning systems, automotive cooling systems, etc.

[0003] In the Chinese patent application number 202222725742.3, a heat exchanger with easy maintenance of fins is disclosed. The screws are turned out, and then the movable plate is rotated out from the inside of the L-shaped limit plate, and then the two sets of L-shaped connecting blocks are removed from the fixed block, driving the two sets of connecting plates to separate, thereby removing each set of fin body one and fin body two from the heat exchange tube. At this time, the staff can wipe and clean it for maintenance.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the above-mentioned device fixes the fins at both ends of the exchange tube by screws, but lacks a fixing mechanism in the middle of the exchange tube, which easily causes a gap between the fin body in the middle and the exchange tube, resulting in low heat transfer efficiency. At the same time, two sets of screws need to be removed when disassembling it, wasting working time.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0007] The hot air energy fin heat exchanger provided in this application adopts the following technical solution:

[0008] A hot air fin heat exchanger includes a vertical plate, wherein horizontal plates are welded to the upper and lower ends of the vertical plate, a plurality of exchange tubes are installed between the vertical plates, and the exchange tubes are connected by connecting tubes. The vertical plate is provided with a plurality of slots matching the exchange tubes, each of the slots is provided with a first thread groove, each of the exchange tubes is sleeved with a rotating tube matching the slot, the rotating tube is provided with a second thread groove matching the first thread groove, and a fixing mechanism is provided on the exchange tube.

[0009] Preferably, a plurality of fin bodies 1 and fin bodies 2 are symmetrically sleeved on the outer wall of the exchange tube, and two sets of connecting plates are welded and installed on the fin bodies 1 and fin bodies 2.

[0010] Preferably, convex grooves are symmetrically provided on the fin body 1 and the fin body 2, and the convex grooves extend into the vertical plate.

[0011] Preferably, the fixing mechanism comprises an I-shaped bar movably mounted on the vertical plate, and the I-shaped bar cooperates with the two groups of convex grooves.

[0012] Preferably, two groups of stoppers cooperating with the I-shaped strip are fixedly mounted on the exchange tube, and a limit block cooperating with the I-shaped strip is fixedly mounted on the rotating tube.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] The convex grooves on the two groups of connecting plates are matched with each other to form an I-shape, and then the I-shaped strips are inserted from the vertical plates into the two groups of convex grooves, and the two groups of connecting plates are limited and fixed by the I-shaped strips, thereby fixing the fin body 1 and the fin body 2 on the connecting plates to prevent gaps from being generated between them and the exchange tubes. When the I-shaped strip is completely inserted into the convex groove, the rotating tube is rotated, and the slot fixes the rotating tube through the action of the thread groove 1 and the thread groove 2, and the I-shaped strip is limited by the limit block on the rotating tube to prevent it from moving out of the convex groove, thereby ensuring the heat exchange efficiency and facilitating the disassembly of the fins.

[0021] By adopting the above technical solution, the convex grooves 12 on the two groups of connecting plates 11 are matched with each other to form an I-shape, and then the I-shaped strips 13 are inserted from the vertical plate 1 into the two groups of convex grooves 12, and the two groups of connecting plates 11 are limited and fixed by the I-shaped strips 13, and then the fin body 1 9 and the fin body 2 10 on the connecting plate 11 are fixed. By fixing the entire section of the connecting plate 11, it is possible to effectively prevent a gap from being generated between it and the exchange tube 3.
