Technical Field

[0001] This utility model relates to the technical field of composite plates for heat exchangers, and in particular to a composite plate for heat exchangers with good heat transfer effect. Background Technology

[0002] Composite plates for heat exchangers are plates made of a combination of various materials. These composite materials have high thermal conductivity and are usually composed of metals, ceramics or other high thermal conductivity materials.

[0003] The utility model with announcement number CN208325927U discloses a composite plate placement rack for a spiral plate heat exchanger. The key technical points are as follows: it includes a frame body, the bottom of which is provided with four first telescopic rods arranged in a matrix. Each first telescopic rod is provided with a wheel at its bottom and a first fixing block is fixed at its top. Two front first fixing blocks and a rear first fixing block are horizontally fixed on their opposite sides. A number of first placement racks that can slide along the first slide groove are provided on the first slide groove. A second telescopic rod is provided at the top of each first fixing block and a second fixing block is fixed at the top of each second telescopic rod. A number of second placement racks that can slide along the second slide groove (91) and cooperate with the first placement racks are provided on the second slide groove (91). The thickness of the placement rack can be automatically adjusted according to the thickness of the composite plate. A certain space is provided between each composite plate to maintain ventilation and prevent the composite plate from getting damp.

[0004] Regarding the above-mentioned issues, the following technical defects exist: Composite plates for heat exchangers with good thermal performance are made of a combination of various materials. These composite materials have high thermal conductivity and also exhibit superior characteristics in terms of corrosion resistance and compressive strength. Typically, when connecting the inlet and outlet pipes of the composite plate to the cooling water pipes, flanges and bolts are used. Although the connection of flanges and bolts is very tight, the installation process is extremely cumbersome. Not only is it necessary to align the mounting holes on the two flanges, but tools are also needed to tighten the bolts, which takes a lot of time and is inefficient.

[0005] Therefore, it is necessary to provide a new composite plate for heat exchangers with good heat transfer performance to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that in the existing technology, when connecting the inlet and outlet pipes of the composite plate to the cooling water pipe, the connection is made by flanges and bolts. Although the connection of flanges and bolts is very tight, the installation process is extremely cumbersome. Not only do the mounting holes on the two flanges need to be aligned, but tools are also needed to tighten the bolts, which makes the installation process time-consuming and inefficient.

[0007] To solve the above-mentioned technical problems, this utility model provides a composite plate for heat exchangers with good heat transfer effect, comprising: a composite plate body, an inlet pipe installed on one side of the composite plate body, an outlet pipe installed on the other side of the composite plate body, and a connecting mechanism provided on the side of the composite plate body near the inlet and outlet pipes. The connecting mechanism includes a fixed plate, which is fixedly connected to one side. Two connecting rods are fixedly connected to the inner wall of the fixed plate. A connecting ring is rotatably connected to the arc surface of the connecting rod. A coil spring is slidably connected to both ends of the arc surface of the connecting rod. The two ends of the arc surface of the coil spring are fixedly connected to the connecting ring and one side of the inner wall of the fixed plate, respectively. A telescopic rod is fixedly connected to one end of the arc surface of the connecting ring. A spring is sleeved on one end of the arc surface of the telescopic rod. The two ends of the spring are fixedly connected to the connecting ring and the telescopic rod, respectively. A retaining frame is fixedly connected to the other end of the arc surface of the telescopic rod. Two identical rotating rods are threaded through the inner walls of the two retaining frames. Both rotating rods are threadedly connected to the inner wall of the fixed plate.

[0008] The aforementioned components achieve the following effects: The composite plate body for the heat exchanger, which boasts excellent thermal performance, is composed of a combination of various materials. These composite materials possess highly efficient heat conduction properties, while also exhibiting superior characteristics in terms of corrosion resistance and compressive strength. Typically, the inlet and outlet pipes on the composite plate body are connected to the cooling water pipes using flanges and bolts. Although flange and bolt connections offer excellent tightness, the installation process is extremely cumbersome. It requires aligning the mounting holes on the two flanges and using tools to tighten the bolts, resulting in a significant time commitment and slow installation efficiency. In this case, a connecting mechanism can replace flanges and bolts to connect the inlet and outlet pipes to the cooling water pipes. The connecting mechanism simplifies the connection process, shortens installation time, and improves the efficiency of installing the inlet and outlet pipes to the cooling water pipes.

[0009] Preferably, a plurality of anti-slip grooves are provided at one end of the arc surface of the rotating rod, and the plurality of anti-slip grooves are evenly distributed on the rotating rod.

[0010] The effect achieved by the above components is that the anti-slip groove can increase the rotation speed of the rotating rod within the frame.

[0011] Preferably, a protrusion is fixedly connected to the other end of the arc surface of the rotating rod, and the protrusion is funnel-shaped.

[0012] The effect achieved by the above components is that the protrusion can increase the speed at which the rotating rod connects to the inner wall of the frame.

[0013] Preferably, the connecting rod is a steel rod.

[0014] The above components achieve the following effect: the steel connecting rod has good stability and is not easily deformed.

[0015] Preferably, a protective mechanism is provided at one end of the composite panel body. The protective mechanism includes an outer frame, which is slidably connected to one end of the composite panel body. A protective plate is fixedly connected to the inner wall of the outer frame. Two connecting blocks are fixedly connected to the side of the outer frame near the composite panel body. Contact rods are slidably connected inside the two connecting blocks. One end of the arc surface of each of the two contact rods is fixedly connected to one side of the composite panel body. An adjusting block is fixedly connected to the side of the outer frame near the connecting blocks. An installation rod is slidably connected to the inner wall of the adjusting block. One end of the arc surface of the installation rod is fixedly connected to the composite panel body. A rotating ring is threadedly connected to one end of the arc surface of the installation rod.

[0016] The effect achieved by the above-mentioned components is that when using the composite panel body, the protective mechanism can be installed on one side of the composite panel body. The protective mechanism can prevent foreign objects from entering the composite panel body, avoid reducing heat exchange efficiency, and prevent damage to the composite panel body, thereby improving the durability and service life of the composite panel body.

[0017] Preferably, a friction pad is fixedly connected to the side of the rotating ring near the adjusting block, and the friction pad has a circular cross-section.

[0018] The effect achieved by the above components is that the friction pad can increase the friction between the rotating ring and the adjusting block.

[0019] Preferably, a contact sleeve is fixedly connected to the arc surface of the contact rod.

[0020] The effect achieved by the above components is that the contact sleeve can increase the friction between the contact rod and the inner wall of the connecting block, thereby temporarily limiting the position of the outer frame to one side of the composite board body through the contact sleeve.

[0021] Compared with related technologies, the composite plate for heat exchangers with good heat transfer effect provided by this utility model has the following beneficial effects:

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figures 1 to 6 The present invention provides a composite plate for heat exchangers with good heat transfer effect, comprising: a composite plate body 1, an inlet pipe 4 installed on one side of the composite plate body 1, an outlet pipe 5 installed on the other side of the composite plate body 1, a connecting mechanism 2 provided on the side of the composite plate body 1 near the inlet pipe 4 and the outlet pipe 5, and a protective mechanism 3 provided at one end of the composite plate body 1.

[0034] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The connecting mechanism 2 includes a fixed disk 201, which is fixedly connected to one side. Two connecting rods 202 are fixedly connected to the inner wall of the fixed disk 201. A connecting ring 204 is rotatably connected to the arc surface of each connecting rod 202. A coil spring 203 is slidably connected to both ends of the arc surface of each connecting rod 202. The two ends of the arc surface of the coil spring 203 are fixedly connected to the connecting ring 204 and one side of the inner wall of the fixed disk 201, respectively. A telescopic rod 205 is fixedly connected to one end of the arc surface of the connecting ring 204. A spring 206 is sleeved on one end of the arc surface of the telescopic rod 205. The two ends of the spring 206 are respectively connected to the connecting ring... 204 and telescopic rod 205 are fixedly connected. A retaining frame 207 is fixedly connected to the other end of the arc surface of the telescopic rod 205. Two identical rotating rods 208 are threaded through the inner walls of the two retaining frames 207. Both rotating rods 208 are threadedly connected to the inner wall of the fixed plate 201. The heat exchanger body 1, which has good thermal performance, is a plate composed of multiple materials. These composite materials possess high-efficiency heat conduction performance and also exhibit superior characteristics in terms of corrosion resistance and compressive strength. Typically, the inlet pipe 4 and outlet pipe 5 on the composite plate body 1 are connected to the cooling water pipe. The connection is currently made using flanges and bolts. While this method provides excellent tightness, the installation process is extremely cumbersome. It requires aligning the mounting holes on the two flanges and using tools to tighten the bolts, resulting in a time-consuming and inefficient installation. Connecting mechanism 2 can replace flanges and bolts to connect the inlet pipe 4 and outlet pipe 5 to the cooling water pipeline. This simplifies the connection process, shortens installation time, and improves the efficiency of the inlet pipe 4. To improve the efficiency of installing the water outlet pipe 5 and the cooling water pipe, several anti-slip grooves 209 are provided on one end of the arc surface of the rotating rod 208. The anti-slip grooves 209 are evenly distributed on the rotating rod 208. The anti-slip grooves 209 can improve the rotation speed of the rotating rod 208 within the clamping frame 207. A protrusion 210 is fixedly connected to the other end of the arc surface of the rotating rod 208. The protrusion 210 is funnel-shaped. The protrusion 210 can improve the connection speed between the rotating rod 208 and the inner wall of the clamping frame 207. The connecting rod 202 is a steel rod. The steel connecting rod 202 has good stability and is not easily deformed.

[0035] In the embodiments of this utility model, please refer to Figures 4 to 6The protective mechanism 3 includes an outer frame 31, which is slidably connected to one end of the composite panel body 1. A protective plate 32 is fixedly connected to the inner wall of the outer frame 31. Two connecting blocks 33 are fixedly connected to the side of the outer frame 31 near the composite panel body 1. Contact rods 34 are slidably connected inside the two connecting blocks 33. One end of the arc surface of each of the two contact rods 34 is fixedly connected to one side of the composite panel body 1. An adjusting block 35 is fixedly connected to the side of the outer frame 31 near the connecting blocks 33. An installation rod 36 is slidably connected to the inner wall of the adjusting block 35. One end of the arc surface of the installation rod 36 is fixedly connected to the composite panel body 1. A rotating ring 37 is threadedly connected to the arc surface of the installation rod 36. At time 1, the protective mechanism 3 can be installed on one side of the composite plate body 1. The protective mechanism 3 can prevent foreign objects from entering the composite plate body 1, avoid reducing heat exchange efficiency, and prevent damage to the composite plate body 1, thereby improving the durability and service life of the composite plate body 1. A friction pad 38 is fixedly connected to the side of the rotating ring 37 near the adjusting block 35. The friction pad 38 has a circular cross section. The friction pad 38 can increase the friction force between the rotating ring 37 and the adjusting block 35. A contact sleeve 39 is fixedly connected to the arc surface of the contact rod 34. The contact sleeve 39 can increase the friction force between the contact rod 34 and the inner wall of the connecting block 33. Thus, the position of the outer frame 31 can be temporarily limited to one side of the composite plate body 1 through the contact sleeve 39.

[0036] The working principle of the composite plate for heat exchangers with good heat transfer effect provided by this utility model is as follows: When the cooling water pipe is brought into contact with the inlet pipe 4, the upper retaining frame 207 can be pressed. The movement of the retaining frame 207 will cause the connecting ring 204 to rotate on the connecting rod 202. The angle of the retaining frame 207 can then be adjusted. Pulling the retaining frame 207 will cause the telescopic rod 205 to stretch. The stretching of the telescopic rod 205 will cause the spring 206 to deform. At this point, the upper retaining frame 207 will come into contact with one side of the cooling water pipe. The force generated when the spring 206 returns to its original position will then drive the telescopic rod 205 and the retaining frame 207. During movement, the inner wall of the retaining frame 207 will abut against one end of the cooling water pipe. At this time, the angle of the lower retaining frame 207 is adjusted using the same method so that the lower retaining frame 207 is at the other end of the cooling water pipe. Then, the rotating rod 208 can be rotated within the two retaining frames 207 to fix the cooling water pipe within the two retaining frames 207. When the rotating rod 208 contacts the inner wall of the fixing plate 201, the rotating rod 208 will drive the spring 206 and the telescopic rod 205 to move. Thus, the rotating rod 208 can squeeze the cooling water pipe and the inlet pipe 4, thereby improving the fixation of the inlet pipe 4 and the cooling water pipe.

[0037] When the inner wall of the connecting block 33 comes into contact with the arc surface of the contact rod 34, the inner wall of the adjusting block 35 can come into contact with the mounting rod 36. At this time, the rotating ring 37 can be rotated on the mounting rod 36, and the adjusting block 35 can be fixed on the mounting rod 36 by the rotating ring 37. At this time, the outer frame 31 and the protective plate 32 can be fixed on one side of the composite board body 1, and the surface of the composite board body 1 can be protected by the protective plate 32.

[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
