[0027] Working principle of this utility model:

[0028] Six identical bottom connecting rods 13 are fixedly provided on the bottom rectangular frame 11, and each bottom connecting rod 13 has a small hole on the side. A top rectangular frame 14 is fixedly provided on the upper end of the bottom rectangular frame 11, and six identical top connecting rods 16 are fixedly provided on the top rectangular frame 14, and each top connecting rod 16 has the same small hole as that on the bottom connecting rod 13, and the upper and lower positions of the bottom connecting rods 13 and the top connecting rods 16 correspond to each other. Two identical placement racks 19 are fixedly provided on the front and rear sides of the upper end of the top rectangular frame 14, and a fan 20 is placed on the placement rack 19, so that it can blow downward toward the cooler, accelerate heat exchange, and improve the heat exchange efficiency of the cooler.

[0029] A heat dissipation pipe is connected between the bottom connecting rod and the top connecting rod, so that the heat dissipation pipe is fixed through small holes on the bottom connecting rod and the top connecting rod. Fins are fixed on the heat dissipation pipe, and two adjacent fins are connected to improve stability.

[0030] The lower end of the heat dissipation pipe is bent and connected, and the upper end of the heat dissipation pipe is connected with a stainless steel angle pass, so that two adjacent heat dissipation pipes can be connected, so that each heat dissipation pipe is connected to form a whole.

[0031] Two identical support columns are fixed between the two bottom connecting rods on the left and right sides. Each support column has four identical threaded holes at the lower end, so that it can be fixed to the ground by bolts, thereby fixing the whole to the ground. At the same time, it is fixed by secondary grouting after pre-installation and vertical calibration.

[0032] A protective net is fixed on the top rectangular frame. The protective net is made of metal and can wrap the fan to prevent large particles or other impurities from entering.

[0033] When the whole is installed, the support column 12 is fixed to the ground by bolts, and then fixed by secondary irrigation after pre-installation and vertical calibration. When working, the fan 20 is started, so that the wind can blow downward, thereby accelerating the heat exchange on the surface of the fin 18, improving the heat exchange efficiency, and reducing the temperature of the alkali solution. When hydrogen leaks, the fan 20 can rotate in the opposite direction to draw the hydrogen upward, thereby suppressing fire and explosion.

[0034] The present invention utilizes air in the atmospheric environment as a cold source, adopts an explosion-proof fan to accelerate gas flow downward, and performs forced heat exchange by extruding finned tubes made of aluminum material with good heat transfer performance, thereby improving the heat exchange efficiency of the alkali liquid cooler.

[0035] The connections between the heat exchange finned tubes of the product are all located at the top of the alkali liquid cooler, using high-pressure NPT angle connection, advanced technology, compact and solid structure, excellent sealing performance, safe and reliable, and convenient for equipment maintenance and repair. The bottom uses a polished stainless steel U-shaped elbow. This design reduces the use of connectors between finned tubes, further improves the reliability of the equipment, reduces the risk of leakage, and also reduces costs. It has the advantages of compact structure, small footprint, easy maintenance and saving material costs.
