[0004] However, the existing technology has defects. The heat exchange fins inside the core are usually welded, which makes it difficult to separate the fins from the core frame, making it difficult to replace the fins. When some fins are damaged due to pressure or other conditions, the entire core may need to be replaced, resulting in high maintenance costs. Therefore, a polymer core heat exchanger is proposed.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] A polymer core heat exchanger, such as Figure 1-Figure 5 As shown, it includes a frame 1, and multiple groups of partitions 2 are fixed inside the frame 1. The partitions 2 separate the multiple groups of core assemblies. Multiple groups of core assemblies are installed inside a group of heat exchangers. The specific number of core assemblies is customized and suitable for different models of heat exchangers. A core assembly for heat exchange is fixed between every two groups of partitions 2. The core assembly includes two groups of side frames 5. The two groups of side frames 5 are symmetrically arranged, and the two groups of side frames 5 are respectively fixed on the side surfaces of the two groups of partitions 2. The backs of the two groups of side frames 5 are commonly fixed with a back frame 3. The middle parts of the back frame 3 and the side frames 5 are hollow to facilitate airflow. Multiple groups of fins 7 are commonly clamped between the two groups of side frames 5 and the back frame 3. The two groups of side frames 5 are fixed with a front frame 13 on the side away from the back frame 3 by bolts. The two groups of front frames 13 are used to limit the front end of the fin 7. The upper ends of the two groups of side frames 5 are commonly fixed with a cover plate 15.

[0026] By improving the polymer core structure of the heat exchanger, two groups of side frames 5, one group of back frames 3 and two groups of front frames 13 form an outer frame. The cover plate 15 closes the upper end of the outer frame to prevent dust from falling on the fins 7. The fins 7 are installed inside the outer frame in a snap-fit manner. When the fins 7 are damaged and need to be replaced, the front frame 13 can be removed to pull out and replace the fins 7, which makes it easy to disassemble the fins 7 from the core assembly, and the fins 7 are easy to replace, thereby reducing maintenance costs.

[0027] like Figure 3 、 Figure 4 As shown, multiple groups of mounting slots 4 are provided on both sides of the back frame 3 , and the multiple groups of mounting slots 4 are arranged in a linear array. Two groups of plug-in plates 8 are fixed to one end of the fin 7 , and the two groups of plug-in plates 8 are plugged into the mounting slots 4 .

[0028] During installation, the two sets of inserting plates 8 at one end of the fin 7 are plugged into the installation grooves 4 on both sides, thereby limiting and clamping one end of the fin 7 .

[0029] like Figure 3 As shown, the two groups of side frames 5 are fixed with multiple groups of support plates 6 on one side close to the fins 7. The multiple groups of support plates 6 are arranged in a linear array. The support plates 6 are used to support the end of the fin 7 away from the mounting groove 4. The number of support plates 6 is the same as the number of fins 7.

[0030] One end of the fin 7 is mounted by being clipped into the mounting groove 4 and the inserting plate 8, and the side surface of the other end is supported by the supporting plate 6. The supporting plate 6 supports each group of fins 7, making it easy to pull the fins 7 out from the core assembly.

[0031] like Figure 1 、 Figure 2 、 Figure 5 As shown, the two groups of front frames 13 are both set to be "L"-shaped, and the two groups of front frames 13 are respectively located on both sides of the front of the fin 7. One side of the two groups of front frames 13 is fixed with multiple groups of limiting components, and the multiple groups of limiting components are used to limit the multiple groups of fins 7. The limiting components include two groups of dividing plates 14, and the two groups of dividing plates 14 are both fixed on one side of the front frame 13, and the two groups of dividing plates 14 are respectively in contact with the front and back of the fin 7.

[0032] The two sets of front frames 13 are fixedly connected to the side frames 5 on both sides by bolts, and are used to tighten and limit the front end of the fin 7 to prevent the fin 7 from falling off. When the front frame 13 is installed, the dividing plate 14 on the front frame 13 is plugged into the fin 7 so that the dividing plate 14 abuts against the front and back sides of the fin 7 to prevent the fin 7 from vibrating up and down inside the frame 1.

[0033] like Figure 5 As shown, a cavity 9 is opened inside the fin 7, and a bent plate 11 is inserted into the cavity 9. The shape of the bent plate 11 is set to be wavy, and side plates 10 are fixed on both sides of the bent plate 11. The two groups of side plates 10 are fixed to the inner wall of the cavity 9 by bolts.

[0034] The cavity 9 facilitates heat exchange inside the fin 7, and the bent plate 11 increases the heat exchange area inside the cavity 9, thereby improving the heat exchange effect of the heat exchanger. The bent plate 11 is installed inside the cavity 9 through two sets of side plates 10, which makes it easy to pull the bent plate 11 out of the cavity 9 and facilitate disassembly and assembly.

[0035] like Figure 5 As shown, a through hole 12 is formed through the bending plate 11 , and the direction in which the through hole 12 is opened is perpendicular to the direction in which the bending plate 11 is inserted into the cavity 9 .

[0036] The perforations 12 increase the connectivity of the surface of the bent plate 11 and interfere with the heat exchange airflow inside the fins 7, thereby increasing the airflow range and improving the heat exchange effect of the heat exchanger.

[0037] The working principle of the polymer core heat exchanger provided by the utility model is as follows:

[0038] By improving the polymer core structure of the heat exchanger, two groups of side frames 5, one group of back frame 3 and two groups of front frames 13 form an outer frame, and the cover plate 15 closes the upper end of the outer frame to prevent dust from falling on the fins 7. The fins 7 are installed inside the outer frame in a snap-on manner. When the fins 7 are damaged and need to be replaced, the front frame 13 can be removed to pull out and replace the fins 7, which facilitates the disassembly of the fins 7 from the core assembly. During installation, the fins 7 slide on the upper end of the support plate 6, and the plug-in plate 8 at one end of the fins 7 is plugged into the mounting groove 4 of the back frame 3. The dividing plate 14 of the front frame 13 is aligned with the fins 7 for installation. After the front frame 13 is installed, the fins 7 are replaced, the fins 7 are easy to replace, and the maintenance cost is reduced.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
