Description

Technical Field

[0001] This utility model relates to the field of parallel flow heat exchanger technology, and in particular to a novel parallel flow heat exchanger with a split-flow structure. Background Technology

[0002] Parallel flow heat exchangers are mainly composed of porous flat tubes and corrugated louvered fins. Their heat exchange principle is based on the microchannel theory, which involves inserting a left manifold and a right manifold at both ends of the flat tube, and using baffles on the left and right manifolds to form a series channel.

[0003] Currently, the fins are welded onto the flat tube. If the fins are damaged, it is inconvenient to replace them, and the entire flat tube needs to be replaced, which is costly.

[0004] An existing publicly available technical solution, CN212585531U, discloses a novel parallel flow heat exchanger with a split-flow structure, comprising: a heat exchanger body, a flat tube, fins, and an ultrasonic generator. The heat exchanger body has a flow tube at its top and a flat tube inside. The flat tube has slots on both its front and rear sides, and fins are mounted on these slots. Each fin has a locking block that engages with the slot. An ultrasonic generator is mounted on the side wall of the heat exchanger body. The fins are secured in the slots by the locking blocks for a detachable connection. When a fin is damaged, it can be individually removed and replaced without disassembling and replacing the entire flat tube, thus reducing maintenance costs.

[0005] In actual implementation, the above technical solution only fixes the fins with a single layer of clips and slots, which has limited stability. In particular, when combined with the vibration of the ultrasonic transducer, it can easily cause the fins to fall off. Summary of the Invention

[0006] The purpose of this utility model is to provide a novel parallel flow heat exchanger with a split-flow structure, which can improve the connection stability between the V-shaped fins and the connecting flat tube by using an anti-detachment component to ensure that the abutment plate and the connecting flat tube abut against each other and the abutment plate presses the connecting flat tube tightly, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel parallel flow heat exchanger with a split structure, comprising a heat exchanger body, wherein multiple sets of equidistant and uniformly distributed connecting flat tubes are arranged between the heat exchanger bodies, and V-shaped fins are installed between two sets of connecting flat tubes, and anti-detachment components for preventing the V-shaped fins from falling off are installed inside the V-shaped fins, and a positioning block and a positioning groove adapted to the positioning block are provided at the connection between the V-shaped fins and the connecting flat tubes;

[0008] The anti-detachment component includes a sliding abutment plate, and a fixing bracket is provided on one side of the abutment plate, the fixing bracket being fixed to the V-shaped fin.

[0009] Preferably, a guide slide rod is provided between the abutment plate and the fixed bracket, and a guide sleeve is sleeved on the outside of the guide slide rod.

[0010] Preferably, a fixing member is fixedly installed inside the guide slide rod, and a lead screw sleeve is fixedly installed inside the fixing member, and an adjusting lead screw is installed inside the lead screw sleeve.

[0011] Preferably, one end of the adjusting screw is fixedly connected to a transmission worm gear, and the other end of the transmission worm gear is provided with a support shaft in the middle, the support shaft being installed inside the fixed bracket through a bearing.

[0012] Preferably, a transmission worm is meshed with one side of the transmission worm gear, and the transmission worm passes through the top of the fixed bracket and is connected to a knob.

[0013] Preferably, the guide slide rod is provided with support springs on both the left and right sides, and a limiting telescopic rod passing through the support springs. The two ends of the limiting telescopic rod are respectively connected to the fixed bracket and the abutment plate.

[0014] Preferably, the surface of the abutment plate is provided with an installation groove, and the inside of the installation groove is bonded with anti-slip rubber, the anti-slip surface of the anti-slip rubber being in contact with the connecting flat tube.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By adjusting the position of the abutment plate through the anti-detachment component, the abutment plate and the connecting flat tube abut against each other, and the abutment plate presses the connecting flat tube tightly, which can improve the connection stability between the V-shaped fins and the connecting flat tube.

[0017] 2. Multiple sets of anti-slip rubber are used to increase the friction between the abutment plate and the connecting flat tube, and the support spring and the limiting telescopic rod can extend and retract as the position of the guide slide rod is adjusted, thus limiting the movement direction of the guide slide rod.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A novel parallel flow heat exchanger with a split-flow structure includes a heat exchanger body 1, multiple sets of equidistant and uniformly distributed connecting flat tubes 2 are arranged between the heat exchanger bodies 1, V-shaped fins 4 are installed between two sets of connecting flat tubes 2, and anti-detachment components 3 are installed inside the V-shaped fins 4 to prevent the V-shaped fins 4 from falling off. A positioning block 5 is provided at the connection between the V-shaped fins 4 and the connecting flat tubes 2, and a positioning slot adapted to the positioning block 5 is provided.

[0028] The anti-detachment component 3 includes a slidable abutment plate 301, and a fixing bracket 305 is provided on one side of the abutment plate 301, which is fixed to the V-shaped fin 4.

[0029] By adopting the above technical solution, a heat exchanger flow tube is also provided on the heat exchanger body 1. When the V-shaped fin 4 is damaged and needs to be replaced, the position of the abutment plate 301 is adjusted so that the abutment plate 301 is separated from the connecting flat tube 2. The connecting flat tube 2 can be unlocked, and the V-shaped fin 4 and the connecting flat tube 2 can be separated by the positioning slot and the positioning block 5, so that the V-shaped fin 4 can be quickly disassembled. The abutment plate 301 abuts against the two sets of connecting flat tubes 2 on both sides of the V-shaped fin 4, which can improve the stability of the connection between the connecting flat tube 2 and the V-shaped fin 4.

[0030] Specifically, such as Figures 2 to 4 As shown, a guide slide rod 302 is provided between the abutment plate 301 and the fixed bracket 305, and a guide sleeve 303 is sleeved on the outside of the guide slide rod 302. The guide slide rod 302 can slide inside the guide sleeve 303. A fixing member 312 is fixedly provided inside the guide slide rod 302, and a screw sleeve 313 is fixedly provided inside the fixing member 312. An adjusting screw 311 is installed inside the screw sleeve 313. The screw sleeve 313 can move on the adjusting screw 311, thereby driving the guide slide rod 302 to slide inside the guide sleeve 303 through the fixing member 312. The end of the adjusting screw 311 is suspended and located at the center of the guide slide rod 302. The guide slide rod 302 has a hollow structure.

[0031] One end of the adjusting screw 311 is fixedly connected to a transmission worm gear 310, and a support shaft 309 is provided in the middle of the other end of the transmission worm gear 310. The support shaft 309 is installed inside the fixed bracket 305 through a bearing. The support shaft 309 is used to support the transmission worm gear 310 without affecting its normal rotation. A transmission worm 308 is meshed with one side of the transmission worm gear 310, and a knob 304 is connected to the top of the fixed bracket 305 through the transmission worm 308. Rotating the knob 304 will drive the transmission worm 308 to rotate. The transmission worm 308 drives the transmission worm wheel 310 to rotate, and the rotation of the transmission worm wheel 310 drives the adjusting screw 311 to rotate. The left and right sides of the guide slide rod 302 are provided with support springs 306 and limiting telescopic rods 307 passing through the support springs 306. The two ends of the limiting telescopic rods 307 are respectively connected to the fixed bracket 305 and the abutment plate 301. The support springs 306 and the limiting telescopic rods 307 can extend and retract as the position of the guide slide rod 302 is adjusted, thereby limiting the movement direction of the guide slide rod 302.

[0032] The surface of the abutment plate 301 is provided with an installation groove 315, and the inside of the installation groove 315 is bonded with anti-slip rubber 314. The anti-slip surface of the anti-slip rubber 314 is in contact with the connecting flat tube 2. Multiple sets of anti-slip rubber 314 are used to increase the friction between the abutment plate 301 and the connecting flat tube 2.

[0033] By adopting the above technical solution, rotating the knob 304 can drive the transmission worm 308 to rotate, and the transmission worm 308 can drive the transmission worm wheel 310 to rotate. After the transmission worm wheel 310 rotates, it can drive the adjusting screw 311 to rotate. At this time, the screw sleeve 313 can move on the adjusting screw 311, thereby driving the guide slide rod 302 to slide inside the guide sleeve 303 through the fixing member 312, thereby adjusting the position of the guide slide rod 302. The support spring 306 and the limiting telescopic rod 307 can extend and retract as the position of the guide slide rod 302 is adjusted, thereby limiting the movement direction of the guide slide rod 302.

[0034] Working principle: The V-shaped fins 4 and the connecting flat tube 2 are installed through the positioning slot and positioning block 5. Rotating the knob 304 drives the transmission worm gear 308 to rotate, which in turn drives the transmission worm wheel 310 to rotate. After the transmission worm wheel 310 rotates, it drives the adjusting screw 311 to rotate. At this time, the screw sleeve 313 can move on the adjusting screw 311, thereby driving the guide slide rod 302 to slide inside the guide sleeve 303 through the fixing part 312, thereby adjusting the position of the guide slide rod 302. The support spring 306 and the limiting telescopic rod 307 can extend and retract with the position adjustment of the guide slide rod 302, limiting the movement direction of the guide slide rod 302, so that the abutment plate 301 abuts against the connecting flat tube 2. The abutment plate 301 presses the connecting flat tube 2, which can improve the connection stability between the V-shaped fins 4 and the connecting flat tube 2.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
