Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a seal for an air heat exchanger. Background Technique

[0002] The plate-fin heat exchanger utilizes the disturbance of the fins to the fluid, causing the boundary layer to break continuously, so it has a large heat transfer coefficient; at the same time, due to the high thermal conductivity of the metal material for manufacturing the plate-fin heat exchanger, the plate-fin heat exchanger can achieve good heat transfer efficiency. The plate-fin heat exchanger mainly consists of a plate-fin heat exchanger core and a head. The plate-fin heat exchanger core mainly consists of seals, partitions and fins. As an important component of the plate-fin heat exchanger, the seal can play the role of sealing the heat medium channel and the refrigerant channel, and providing a certain support strength for the fins.

[0003] For example, patent (CN213748033U) discloses a plate-fin heat exchanger for an automobile engine, including a seal and a partition; the seal includes a seal main body, a first engaging portion and a second engaging portion; the seal main body is in a strip shape; the extending direction of the seal main body is the horizontal direction; the first engaging portion is arranged on the upper surface of the seal main body; the second engaging portion is arranged on the lower surface of the seal main body; the second engaging portion and the first engaging portion are symmetrically arranged up and down; the partition is provided with a third engaging portion and a fourth engaging portion that cooperate with the seal; by arranging engaging portions that can cooperate and connect with each other on the seal main body and the partition, on the one hand, the assembly process of the seal and the partition can be simplified, the assembly time of the two can be shortened, and the working efficiency of the staff can be improved; on the other hand, the brazing area of the seal and the partition is increased, the connection strength between the two is improved, and the welding position of the seal and the partition is prevented from breaking, thereby prolonging the service life of the seal and the partition.

[0004] When using the above technology, it is found that the following technical problems exist in the prior art: during the assembly of the heat exchanger, the partition and the seal are generally fixed by welding, which is inconvenient to replace the seal in the later stage, the disassembly process is cumbersome, and the welding points are prone to corrosion and leakage, affecting the heat transfer effect of the heat exchanger. Therefore, we designed a seal for an air heat exchanger to provide another technical solution for the above technical problems. Content of the Utility Model

Linkage rods are slidably connected to both ends inside the guide grooves. One end of the linkage rod is rotatably connected to the driving block. The other end of the driving block is rotatably connected to the buffer pad.

[0010] As a preferred embodiment of the seal for air heat exchanger provided by the present utility model, the thread directions of the two threaded rods are opposite.

[0011] As a preferred embodiment of the seal for air heat exchanger provided by the present utility model, a second fixing block is fixed at one end of both sides of the seal body.

[0026] Embodiment 1

[0027] Please refer to Figures 1 - 4 , the seal for an air heat exchanger, includes a seal body 1. Fixed grooves 2 are provided on both sides inside the seal body 1. An isolation pad 10 is slidably connected inside the seal body 1. Buffer pads 9 are fixed on one side of the two fixed grooves 2 close to each other. The buffer pads 9 effectively provide stability and sealing for the partition board. Protective pads 8 are slidably connected on one side of the two fixed grooves 2 away from each other. Positioning mechanisms for driving the protective pads 8 to clamp the partition board are provided on both sides of the seal body 1;

[0028] During use, by assembling the seal on the heat exchanger, at this time the fixed grooves 2 are aligned with the partition board, and then the positioning mechanism is started to drive the protective pads 8 to move towards the buffer pads 9, so that the protective pads 8 clamp the partition board. Therefore, it is convenient to disassemble and replace the seal, thus ensuring the heat exchange effect of the heat exchanger;

[0029] The positioning mechanism includes a transmission rod 5, a threaded rod 4, a driving block 7, a first fixing block 11 and a hand turntable 12. The two ends of both sides of the seal body 1 are rotatably connected to the first fixing blocks 11. The transmission rod 5 is rotatably connected inside the first fixing blocks 11. Threaded rods 4 are fixed at both ends of the outer side of the transmission rod 5. The two threaded rods 4 have opposite helix directions. The driving block 7 is threadedly connected to the outer side of the threaded rod 4. Hand turntables 12 are fixed at both ends of the transmission rod 5;

[0030] Guide grooves 3 are provided on both sides inside the seal body 1. Linkage rods 13 are slidably connected to both ends inside the guide grooves 3. One end of the linkage rod 13 is rotatably connected to the driving block 7, and the other end of the driving block 7 is rotatably connected to the buffer pad 9;

[0031] Specifically, by rotating the hand turntable 12 to drive the transmission rod 5 and the threaded rod 4 to rotate, the threaded rod 4 drives the two driving blocks 7 to move towards the ends away from or close to each other. When the two driving blocks 7 move towards the ends away from each other, the driving blocks 7 drive the linkage rods 13 to press on the protective pads 8. Therefore, the protective pads 8 clamp the partition board, so as to clamp the partition board and effectively replace and disassemble the seal body 1;

[0032] Second fixing blocks 14 are fixed at one end of both sides of the seal body 1. A plug pin 15 is slidably connected inside the second fixing blocks 14. One end of the plug pin 15 is clamped with the hand turntable 12;

[0033] A number of limiting grooves 6 are provided inside the hand turntable 12, and one end of the plug pin 15 is slidably connected to the corresponding limiting groove 6;

[0034] Further, when the hand turntable 12 is rotated to drive the transmission rod 5, the threaded rod 4 and the linkage rod 13 to move the protective pad 8, and the protective pad 8 clamps the partition board, and then the plug pin 15 is slidably connected to the limiting groove 6 inside the hand turntable 12, so as to improve the stability of the protective pad 8 on the partition board.

[0035] The using process of the seal for the air heat exchanger provided by the utility model is as follows:

[0036] Working principle: During the using process, by assembling the seal on the heat exchanger, the hand turntable 12 is rotated to drive the transmission rod 5 and the threaded rod 4 to rotate, so that the threaded rod 4 drives the two driving blocks 7 to move towards the ends away from or close to each other. When the two driving blocks 7 move towards the direction away from each other, the driving blocks 7 drive the linkage rod 13 to apply pressure to the protective pad 8. Therefore, the protective pad 8 clamps the partition board, so as to clamp the partition board, and effectively replace and disassemble the seal body 1;

[0037] When the protective pad 8 and the buffer pad 9 fix the partition board, at this time, the plug pin 15 is slidably connected to the limiting groove 6 inside the hand turntable 12, so as to improve the stability of the protective pad 8 on the partition board.
