Description

Technical Field

[0001] This utility model relates to a brazed plate heat exchanger with a limiting groove. Specifically, it relates to a brazed plate heat exchanger with a limiting groove. Background Technology

[0002] Brazed plate heat exchangers with limiting grooves mainly feature limiting structures designed at the edges or specific locations of the plates. These structures are used to precisely position the plates, prevent misalignment or excessive compression during assembly, and improve equipment stability and heat exchange efficiency. These products are often used in applications where high structural precision is required.

[0003] To ensure uniform stress during installation, brazed plate heat exchangers with locating grooves have multiple bolts distributed on both sides, and each bolt requires an operation to be fixed, which makes the assembly operation of conventional brazed plate heat exchangers with locating grooves quite troublesome.

[0004] To address this issue, we propose a brazed plate heat exchanger with a limiting groove to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the assembly operation of conventional brazed plate heat exchangers with locating grooves is relatively troublesome, and to propose a brazed plate heat exchanger with locating grooves.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A brazed plate heat exchanger with a limiting groove includes a frame. Steel wire ropes are installed within the frame, distributed on both sides. One end of one side of the steel wire rope is fixedly connected to a threaded seat, and the other end is fixedly connected to a mounting seat. A first bolt is movably inserted into the mounting seat, and the first bolt is threadedly matched with the threaded seat. A first pressure plate is slidably fitted onto the frame. The first pressure plate is fitted onto the frame, and then the heat exchange plates are secured within the frame. The steel wire ropes are then secured to the side of the first pressure plate. The first bolt is then passed through the mounting seat and tightened into the threaded seat. The first bolt contracts the mounting seat and threaded seat, which in turn tightens the steel wire ropes. The steel wire ropes tighten the first pressure plate and the frame, and the first pressure plate compacts the internal heat exchange plates. This design ensures proper stress distribution while reducing the amount of bolting required and improving installation efficiency.

[0008] Preferably, the frame includes a second pressure plate, one side of which is fixedly connected to a guide bolt.

[0009] Preferably, the second pressure plate has a threaded opening in its groove. This threaded opening facilitates the threaded connection between the wire rope and the second pressure plate.

[0010] Preferably, the wire rope includes a rope body, one end of which is fixedly connected to a second bolt, the second bolt being threaded into a threaded opening. By using the threaded opening to fix the second bolt, one end of the rope body is stabilized on the second pressure plate, preventing the wire rope from detaching from the frame and improving the stability of the wire rope installation with the frame.

[0011] Preferably, the first pressure plate includes a plate body, and a slot is provided on the side of the plate body. The plate body is slidably sleeved on the guide bolt, and the rope body is movably locked in the slot. By using the slot to lock the rope body, the locking position between the rope body and the plate body is stabilized. After the first bolt is tightened, the rope body acts on the plate body and the outer periphery of the second pressure plate, increasing the uniformity of force distribution.

[0012] Preferably, the corners of the slot are chamfered. The chamfer reduces the local pressure between the plate and the rope, thus protecting the rope.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. Place the first pressure plate on the frame, then clamp the heat exchange fins inside the frame. Next, clamp the wire rope on the side of the first pressure plate, then pass the first bolt through the mounting base and tighten it in the threaded seat. Use the first bolt to contract the mounting base and threaded seat, and use the mounting base and threaded seat to tighten the wire rope. Tighten the first pressure plate and frame through the wire rope, and use the first pressure plate to compact the internal heat exchange fins. This ensures the distribution of stress while reducing the amount of bolting and improving installation efficiency.

[0015] 2. Use the threaded joint to install and fix the second bolt, stabilize one end of the rope on the second pressure plate, prevent the wire rope from detaching from the frame, and improve the stability of the wire rope installation with the frame.

[0016] 3. Use the slot to attach the rope to stabilize the connection position between the rope and the plate. After tightening the first bolt, use the rope to act on the plate and the outer periphery of the second pressure plate to increase the uniformity of force distribution. Attached Figure Description

[0022] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.

[0023] like Figure 1 As shown, a brazed plate heat exchanger with a limiting groove includes a frame 2, in which steel wire ropes 3 are installed. The steel wire ropes 3 are distributed on both sides of the steel wire ropes 3. One end of one side of the steel wire rope 3 is fixedly connected to a threaded seat 5, and one end of the steel wire rope 3 on the other side is fixedly connected to a mounting seat 1. A first bolt 6 is movably inserted in the mounting seat 1. The first bolt 6 is threadedly matched with the threaded seat 5. A first pressure plate 4 is slidably sleeved on the frame 2.

[0024] like Figure 1 and 2 As shown, the frame 2 includes a second pressure plate 21, one side of which is fixedly connected to a guide bolt 22. The guide bolt 22 guides the first pressure plate 4 to slide, and at the same time, the guide bolt 22 constrains the internal heat sink.

[0025] like Figure 2 As shown, the second pressure plate 21 has a threaded opening 23 in its groove. The threaded opening 23 is used to connect the wire rope 3.

[0026] like Figure 1 and 3 As shown, the wire rope 3 includes a rope body 31, one end of which is fixedly connected to a second bolt 32. The second bolt 32 is threaded into a threaded opening 23. By using the threaded opening 23 to fix the second bolt 32, one end of the rope body 31 is stabilized on the second pressure plate 21, preventing the wire rope 3 from detaching from the frame 2.

[0027] like Figure 1 , 2 As shown in Figure 4, the first pressure plate 4 includes a plate body 41, with a slot 42 on the side of the plate body 41. The plate body 41 is slidably sleeved on the guide bolt 22, and the rope 31 is movably locked in the slot 42. By using the slot 42 to lock the rope 31, the locking position between the rope 31 and the plate body 41 is stabilized. After tightening the first bolt 6, the rope 31 acts on the outer periphery of the plate body 41 and the second pressure plate 21, increasing the uniformity of force distribution.

[0028] like Figure 4As shown, the corners of the slot 42 are chamfered 43. The chamfer 43 is used to reduce the local pressure between the plate 41 and the rope 31.

[0029] Working principle: The first pressure plate 4 is placed on the frame 2, and then the heat exchanger is clamped inside the frame 2. Then the wire rope 3 is clamped on the side of the first pressure plate 4. The first bolt 6 is passed through the mounting base 1 and tightened in the threaded seat 5. The first bolt 6 is used to shrink the mounting base 1 and the threaded seat 5, and the mounting base 1 and the threaded seat 5 are used to tighten the wire rope 3. The wire rope 3 tightens the first pressure plate 4 and the frame 2. The first pressure plate 4 compacts the internal heat exchanger, ensuring the force distribution while reducing the amount of bolting by half.
