[0002] A circulating water tank is a device used in a circulating cooling water system. Its main function is to maintain the highest water level plane and allow air in the water to be discharged from here to avoid being brought into the pipeline system, resulting in air resistance loss. During the processing of the circulating water tank, a high-temperature resistant aluminum alloy plate for the circulating water tank is often required.

[0003] After retrieval, the patent number is CN105003023A, and the name is a high-temperature resistant and fireproof aluminum alloy plate, which includes an aluminum alloy plate arranged at the central position. Through research and analysis, it is found that although it has the advantages of fire prevention and noise reduction, to a certain extent, it also has the following disadvantages.

[0004] For example, during the use of the high-temperature resistant aluminum alloy plate for the circulating water tank mentioned above, it usually does not have a composite and superimposable metal heat insulation layer, resulting in relatively poor heat insulation and heat preservation effects of its main body. And usually, there is no thick coating of two layers of corrosion-resistant coatings on the surface, which is prone to cause certain chemical erosion when immersed in the circulating water tank. To solve the above technical problems, we have designed a high-temperature resistant aluminum alloy plate for a circulating water tank. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-temperature resistant aluminum alloy plate for a circulating water tank, which has the advantages of a composite metal heat insulation layer and resistance to water body erosion, and solves the problems of poor heat insulation effect of the main body and easy being eroded by the water body.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a high-temperature resistant aluminum alloy plate for a circulating water tank, including a first plate body. Heat insulation cavities are opened at the bottom of the first plate body and the top of a second plate body. Honeycomb connectors are heat-melt connected to opposite sides of the inner cavity of the heat insulation cavity. A honeycomb plate is welded in the inner cavity of the honeycomb connector. The first plate body includes a first base plate, and the second plate body includes a second base plate.

[0007] Preferably, a third metal heat insulation layer is welded to the top of the second base plate, and a fourth metal heat insulation layer is welded to the top of the third metal heat insulation layer.

[0009] Preferably, a first protective coating is welded to the top of the second metal heat insulation layer, and a second protective coating is welded to the top of the first protective coating.
