The left heat exchange plate 1, the middle heat exchange plate 2 and the right heat exchange plate 3 are connected through fastener and form a complete heat exchange device. The structure of the left heat exchange plate 1 and the right heat exchange plate 3 is symmetrical, the left heat exchange plate 1 is located at the leftmost side, the right heat exchange plate 3 is located at the rightmost side, and the middle is sequentially arranged by N middle heat exchange plates 2. This modular heat exchange plate can flexibly adjust the number of middle heat exchange plates according to actual demand, not only facilitates the user to customize according to specific heat exchange demand, but also greatly simplifies the assembly and maintenance process and reduces the cost.

[0026] The left heat exchange plate 1, the middle heat exchange plate 2 and the right heat exchange plate 3 are all provided with upper flow channel 4 and lower flow channel 5, and the structure of the upper flow channel 4 and the lower flow channel 5 is same. The inlet and outlet of the cooling liquid of the upper flow channel 4 and the lower flow channel 5 are all arranged on the same side, the upper flow channel 4 and the lower flow channel 5 are all cooling liquid inlet on the upper, outlet on the lower,

[0027] The left heat exchange plate 1, the middle heat exchange plate 2 and the right heat exchange plate 3 are all connected with the elbow pipe 6 for communicating the upper flow channel 4 and the lower flow channel 5, and the elbow pipe 6 is a U-shaped pipe.

[0028] The front end of the left heat exchange plate 1, the middle heat exchange plate 2 and the right heat exchange plate 3 is all provided with the front sealing plate 7, and the rear end is all provided with the rear sealing plate 8. The inlet and outlet of the upper flow channel 4 and the lower flow channel 5 are all arranged on the front sealing plate 7, and the elbow pipe 6 is connected on the front sealing plate 7.

[0029] The front end plate 7 is connected with horizontal cooling liquid input pipe 9 and cooling liquid output pipe 10. The cooling liquid input pipe 9 is communicated with the inlet of the upper flow channel 4, and is used to guide the cooling liquid into the upper flow channel 4. The cooling liquid output pipe 10 is communicated with the outlet of the lower flow channel 5, and is used to guide the cooling liquid out of the lower flow channel 5. The cooling liquid can flow through the upper flow channel 4 and the lower flow channel 5 of each heat exchange plate efficiently, ensuring that the heat exchange process is uniform and sufficient, and simplifying the pipeline layout, facilitating the installation and maintenance of the system. The cooling liquid input pipe 9 and the cooling liquid output pipe 10 are perpendicular to the left heat exchange plate 1, the middle heat exchange plate 2 and the right heat exchange plate 3. Vertical flanges 11 are fixedly connected to the left and right ends of the cooling liquid input pipe 9 and the cooling liquid output pipe 10, so as to be connected with adjacent heat exchange plates. The flanges 11 realize quick and reliable connection with adjacent heat exchange plates, which not only simplifies the installation process, but also ensures the sealing and stability of the pipeline.

[0030] A flat side end face 12 is arranged at the left and right ends of the front end plate 7 and the rear end plate 8 of the middle heat exchange plate 2. Corresponding side end faces 12 are arranged at the right side of the front end plate 7 and the rear end plate 8 of the left heat exchange plate 1 and the left side of the front end plate 7 and the rear end plate 8 of the right heat exchange plate 3, so as to ensure the close connection of the left heat exchange plate 1, the middle heat exchange plate 2 and the right heat exchange plate 3, and further ensure the air tightness of the heat exchange device, so that the exhaust gas cannot leak out from the gap between the heat exchange plates.

[0031] A plurality of connecting lug plates 13 are vertically fixedly connected to the side end face 12. The side of the connecting lug plate 13 is flush with the side end face 12. During assembly of the heat exchange device, the connecting lug plates 13 on the adjacent side end faces 12 are stably connected by bolts, so as to ensure the close cooperation between the left heat exchange plate 1, the middle heat exchange plate 2 and the right heat exchange plate 3.

A sealing strip (not shown) is arranged in the sealing groove 14, so as to further improve the air tightness of the heat exchange device and ensure the efficiency and reliability of the heat exchange process. The design of the sealing groove 14 and the sealing strip enables the adjacent heat exchange plates to form a reliable sealing interface when connected. The sealing strip is made of elastic materials such as rubber or silicone, which have good elasticity and sealing performance and can adapt to the slight deformation between the heat exchange plates due to temperature changes.

[0033] A plurality of heat dissipation fins 15 are fixedly connected to the left side of the left heat exchange plate 1 and the right side of the right heat exchange plate 3, so as to prevent the temperature of the heat exchange plate from being too high, and enable the heat exchange device to stably and efficiently operate. The heat dissipation fins 15 are equidistantly and obliquely arranged, and are in a sheet shape, extending from the left side of the left heat exchange plate 1 and the right side of the right heat exchange plate 3, and forming a shape similar to a wing. In this way, the heat dissipation area is increased, and the air flow is optimized, and the heat dissipation efficiency is improved. When the heat exchange device operates, the left heat exchange plate 1 will accumulate a certain amount of heat, and the heat will be quickly transferred to the surrounding air through the heat dissipation fins 15, so as to achieve cooling.

[0034] A row of heat exchange fins 16 are fixedly connected to the upper portions of the left heat exchange plate 1, the middle heat exchange plate 2 and the right heat exchange plate 3, and the heat exchange fins 16 are located on the flow channel outer wall of the upper flow channel 4, so as to significantly increase the heat exchange area of the upper flow channel 4, make the heat exchange more sufficient, and improve the heat exchange efficiency.

[0035] A plurality of heat exchange columns 17 are fixedly connected to the right side of the left heat exchange plate 1, the left and right sides of the middle heat exchange plate 2 and the left side of the right heat exchange plate 3, and the heat exchange columns 17 are all perpendicular to the heat exchange plates where they are located, and are uniformly distributed in an array. The heat exchange columns 17 further increase the heat exchange area, and improve the heat exchange efficiency.
