Technical Field
[0001] This utility model relates to the field of heat exchanger technology, specifically a high-stability high-speed train heat exchanger. Background Technology
[0002] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid; it is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food, and many other industrial production processes. In chemical production, heat exchangers are widely used as heaters, coolers, condensers, evaporators, and reboilers.
[0003] Patent CN219674902U discloses a highly stable heat exchanger for high-speed trains. It includes a heat exchanger body and a base for installation. The base has several mounting holes at its edge and several shock-absorbing strips installed in the middle of the front end face of the base. The heat exchanger body has several mounting parts at its edge, and each mounting part has a through hole. The device is fixedly connected by a fixing nut, which reduces the vibration of the heat exchanger body and improves the stability of the heat exchanger operation.
[0004] However, this device, whether it is a damping strip or a damping layer, can only buffer and weaken the vertical vibration force of the heat exchanger body mounted on the base. Horizontal vibration will still affect the connection between the heat exchanger body, the positioning rod and the positioning block, as well as the connection between the positioning block and the adjusting slide rail, which can easily cause structural damage. Therefore, a highly stable high-speed train heat exchanger is proposed to solve the problem that the existing heat exchangers are easily damaged by vibration. Utility Model Content

When the heat exchanger body is installed between the fixed bases, its two ends and bottom are respectively in contact with the first damping pad and the second damping pad, and the damping sleeve is in contact with the locking block.
[0010] Preferably, the shock absorption mechanism includes symmetrically formed grooves on the top of the base plate, a limiting post is fixedly connected to the inner cavity of the groove, a mounting seat is fitted around the outer ring of the limiting post and the two are slidably connected, and a shock absorption seat is fixedly connected to the top of the mounting seat.

[0012] 1. This highly stable high-speed train heat exchanger involves lowering the heat exchanger body and pressing it between the fixed seats, placing it on top of the support base.

A heat exchanger body 3 is mounted on the top of the support seats 2. A fixed seat 4 is located at one end of the support seats 2. A shock-absorbing mechanism 5 is provided between the base plate 1 and the heat exchanger body 3. The fixed seat 4 has symmetrically formed moving grooves 6 facing the heat exchanger body 3. Springs 7 and locking blocks 8 are installed inside the moving grooves 6. The heat exchanger body 3 has a locking block 8 that fits into the moving groove 6. The top edge of one end of the slot 9 and the block 8 is provided with a guide slope 10. The top of the fixed seat 4 is provided with a limiting groove 11. The inner cavity of the limiting groove 11 is provided with a limiting block 12. The top of the limiting block 12 is fixedly connected with a control plate 13. The end of the fixed seat 4 that is in contact with the heat exchanger body 3 is provided with a first shock-absorbing pad 14. The part of the support seat 2 that is in contact with the heat exchanger body 3 is provided with a second shock-absorbing pad 15. The top of the control plate 13 is provided with a slot. The inner cavity of the slot 9 is provided with a shock-absorbing sleeve 16.
[0021] Furthermore, the two ends of the spring 7 are fixedly connected to the moving groove 6 and the locking block 8 respectively. The moving groove 6 passes through the first shock-absorbing pad 14, and the spring 7 is always in a compressed state. The top of the base plate 1 is provided with mounting holes.
[0022] Furthermore, the inner cavity of the limiting groove 11 is interconnected with that of the moving groove 6, the limiting block 12 is fixedly connected to the locking block 8, and the control plate 13 seals the top of the limiting groove 11 and is slidably connected to the fixed base 4.
[0023] Furthermore, the first damping pad 14, the second damping pad 15, and the damping sleeve 16 are all made of elastic rubber. When the heat exchanger body 3 is installed between the fixed bases 4, its two ends and bottom are respectively attached to the first damping pad 14 and the second damping pad 15, and the damping sleeve 16 is attached to the locking block 8.
[0024] Furthermore, the shock absorption mechanism 5 includes grooves 501 symmetrically opened on the top of the base plate 1. The inner cavity of the groove 501 is fixedly connected to a limiting post 502. The outer ring of the limiting post 502 is fitted with a mounting seat 503 and the two are slidably connected. The top of the mounting seat 503 is fixedly connected to a shock absorption seat 504.
[0025] Furthermore, a damping disc 505 is fitted on the top of the damping seat 504. The damping disc 505 is made of elastic rubber. A damping spring 506 is provided at the bottom of the damping seat 504. A limiting ring 508 that matches the groove 501 is provided at the bottom of the damping spring 506. A chamfer 507 is provided on the outer ring of the top of the limiting post 502. When the heat exchanger body 3 is installed between the fixed seats 4, the heat exchanger body 3 and the damping disc 505 are in contact and pressed together.

In addition, with the action of the damping spring 506 and the limiting ring 508 located in the groove 501, the vibration force on the heat exchanger body 3 is further weakened, thereby improving the stability of this train heat exchanger during use.
[0026] Working Principle: When using this highly stable high-speed train heat exchanger, the heat exchanger body 3 is lowered and pressed between the fixed seats 4, placing it on top of the support seat 2. During this process, with the help of the guide ramp 10, the locking block 8 moves into the moving groove 6 and continues to compress the spring 7. When the moving groove 6 and the locking groove 9 are interconnected, the locking block 8 enters the shock-absorbing sleeve 16 in the locking groove 9, thus completing the installation. Subsequently, the first shock-absorbing pad 14, the second shock-absorbing pad 15, and the shock-absorbing sleeve 16 weaken the vibration forces on the heat exchanger body 3 from various directions, solving the problem that existing heat exchangers are easily affected by vibrations. The problem of damage caused by vibration is addressed. When the heat exchanger body 3 needs to be disassembled, the control plate 13 is moved outward through the slot. During the process, the limiting block 12 in the limiting slot 11 can move the locking block 8 out of the locking slot 9, thereby releasing the restriction of the heat exchanger body 3. The control plate 13 always blocks the limiting slot 11 from the top, thereby preventing dust and water vapor from entering the limiting slot 11 and corroding the spring 7. The use of bolts and other fixed connecting parts is eliminated, avoiding the problem of rust at the connection, and improving the convenience of installation and disassembly of the heat exchanger of this train and the stability after installation.
