Thermal Insulation Water Tank

The core working principle of the thermal insulation water tank is multi-layer composite thermal insulation technology. Through the three-layer composite structure of inner tank, insulation layer and outer protective layer, it specifically blocks three heat transfer paths: heat conduction, heat convection and heat radiation, realizing long-term constant temperature insulation of the water storage medium and minimizing heat loss during water storage. The inner tank, as the water storage carrier, adopts corrosion-resistant, food-grade metal material to realize sealed pressure water storage; the middle insulation layer uses high-density insulation material with low thermal conductivity to block the heat conduction path between the inner tank and the outside; the outer protective layer adopts high-strength protective material to isolate air convection and external environmental erosion, while protecting the internal insulation structure from external force damage. This technology complies with the relevant specifications of Standard for Design of Building Water Supply and Drainage GB 50015-2019, and also meets the mandatory requirements of Safety Evaluation Standard for Drinking Water Transmission and Distribution Equipment and Protective Materials GB/T 17219-1998 issued by the State Administration for Market Regulation of China, and fully conforms to the industry technical standards for water supply and drainage equipment issued by the Water Quality Association (WQA). It is an indispensable core supporting equipment in boiler hot water systems, HVAC water supply and industrial heat storage projects.

3. Core Structure and Thermal Insulation Performance Design of AIX Boiler Insulated Water Tank

AIX boiler thermal insulation water tank is specially optimized for high temperature resistance, corrosion resistance, long service life and low heat loss for boiler operation scenarios. It adopts three-layer integrated composite structure design. The core structure includes three core main bodies: food grade pressure inner tank layer, high density thermal insulation layer, high strength outer protective layer, and five functional modules: water inlet and outlet interface, temperature control unit, liquid level monitoring unit, sewage discharge and exhaust unit, manhole maintenance unit. It can realize seamless docking and linkage control with our boiler system and water treatment system. The core structure design is as follows:

1. Food Grade Pressure Inner Tank Layer

As the core water storage carrier of the water tank, the inner tank is made of food grade 304/316L stainless steel, carbon steel rubber lined and other corrosion-resistant materials. It is integrally formed by fully automatic CNC rolling and welding process. The weld seam adopts argon arc welding double-sided forming technology, and passes 24-hour water pressure air tightness test, no leakage and no deformation. The inner wall is mirror polished, which is not easy to scale and breed microorganisms, and can be adapted to the storage of various media such as boiler feed water, domestic hot water, food processing water. It is specially designed for high temperature resistance for boiler high temperature hot water scenarios, and can withstand long-term storage of high temperature media up to 95℃, with a service life of more than 20 years.

2. High Density Thermal Insulation Layer

The insulation layer adopts high-density polyurethane rigid foam material formed by high-pressure integral foaming process, with density ≥38kg/m³, thermal conductivity ≤0.024W/(m·K), and thickness customized from 50mm to 200mm according to the application scenario, no joints and no hollowing, stable thermal insulation performance. For large industrial high-temperature heat storage scenarios, multi-layer composite insulation structure of polyurethane foaming + rock wool + vacuum insulation panel is adopted to further block heat radiation and heat conduction, achieving ultra-long-term insulation effect with 24h temperature drop ≤1.5℃, minimizing the heat loss during the storage of boiler hot water and reducing the energy consumption of repeated heating of the boiler.

3. High Strength Outer Protective Layer

The outer protective layer is made of high-strength protective materials such as 201/304 stainless steel, color steel plate, carbon steel plastic sprayed, with customized thickness from 0.8mm to 2.0mm. The surface is treated with anti-corrosion and anti-rust treatment, with flat and beautiful appearance, impact resistance, aging resistance and corrosion resistance. It can adapt to various installation environments such as indoor, outdoor and open air, effectively isolate external air convection and rain erosion, protect the internal insulation structure from damage, and can customize the appearance color and logo according to user needs, perfectly integrating with the site environment.
