[0002] Air source heat pump water heaters, also known as "air source heat pump water heaters", work on a principle very similar to air conditioners. They use a small amount of electricity to drive the compressor, and the high-pressure liquid working fluid evaporates into a gaseous state in the evaporator after passing through the expansion valve, absorbing a large amount of heat energy from the air. Air source heat pump water heaters require the use of a circulating water tank.

[0003] Currently, the circulating water tanks used in air source heat pump water heaters have poor corrosion resistance, which can cause damage to the circulating water tank due to corrosion, reducing its strength and shortening its service life.

[0027] The inner cavity of the water tank 1 is provided with a heat-conducting pipe 8 in a ring. The heat-conducting pipe 8 is made of 316 stainless steel. With the setting of the insulation layer 5, in low temperature environment, the insulation layer 5 can effectively slow down the rate of water temperature drop and prevent the water in the water tank 1 from freezing and expanding, which may cause cracking. Especially in areas where the winter temperature is below 0℃ for a long time, the insulation layer 5, together with the electric heat tracing system, can completely avoid the risk of freezing and improve the heat preservation performance of the water tank 1.

[0028] The insulation layer 5 is a foamed insulation layer with a thickness of 45-55mm. The paint coating layer 73 provides a hard, smooth and glossy protective layer for the water tank 1.

The heat pipe 8 is made of 316 stainless steel, which has good corrosion resistance and high temperature resistance, and is suitable for various corrosive environments, thus improving the corrosion resistance of the heat pipe 8.

[0031] During use, the stainless steel inner liner 4 provides excellent corrosion resistance. Because it contains metallic elements such as chromium and nickel, it effectively resists the erosion of acids, alkalis, and other chemicals, preventing corrosion. Simultaneously, the high-temperature resistance of the stainless steel inner liner 4 allows for stable operation in complex industrial environments and adaptability to various chemical media. The insulation layer 5 effectively slows down the rate of water temperature drop in low-temperature environments, preventing the water in the tank 1 from freezing and expanding, which could lead to cracking. Especially in areas where winter temperatures are consistently below 0°C, the insulation layer 5, in conjunction with an electric heating system, completely eliminates the risk of freezing, improving the insulation performance of the tank 1. The painted surface layer 73 further enhances the... The water tank 1 provides a hard, smooth, and glossy protective layer. This protective layer is not only aesthetically pleasing but also effectively resists the erosion of rainwater and ultraviolet rays, maintaining its long-lasting luster. It also has excellent corrosion resistance, resisting the erosion of humid environments and chemicals, thereby extending the service life of the circulating water tank. The galvanized layer 71 and the electroplated coating 72 mainly contribute to the corrosion prevention, improved system stability, and economic benefits of the circulating water tank. They also effectively isolate the water tank 1 from contact with corrosive substances, thus extending its service life. The 316 stainless steel material of the heat pipe 8 has good corrosion resistance and high temperature resistance, making it suitable for various corrosive environments and improving the corrosion resistance of the heat pipe 8.
