A phase change energy storage water tank

Abstract

The invention relates to a phase-change energy storage water tank which structurally comprises a water tank body. A phase-change cold storage layer is arranged in the water tank body, flow equalizing water pipes used for water input and water output are arranged on the two opposite side faces of the water tank body in the length direction respectively and comprise main pipes and branch pipes, the branch pipes are arranged in the water tank body, each branch pipe comprises at least one flow dividing pipeline, a plurality of flow equalizing holes are evenly formed in the side pipe walls, facing the inner side walls, of the flow dividing pipelines, turbulent flow hole plates are arranged between the flow equalizing water pipes and the phase-change cold storage layer, evenly-distributed through holes are formed in the turbulent flow hole plates, and a plurality of turbulent flow baffles arranged in the length direction of the water tank body in a spaced mode are arranged between the peripheral side of the water tank body in the length direction and the phase-change cold storage layer. According to the phase-change energy storage water tank, water or refrigerating media can evenly enter the water tank, and the water or the refrigerating media and phase-change materials are further in full contact, are mixed and exchange heat in the water tank, so that the cold storage or cooling effect of the phase-change energy storage water tank is improved.

Description

technical field [0001] The invention relates to an energy storage water tank, in particular to a phase change energy storage water tank using a phase change energy storage medium for cooling. Background technique [0002] The phase change cold storage water tank using phase change material as the cold storage medium has the advantages of large energy storage per unit volume and high cold storage density. The brine or water in the water tank is fully and evenly contacted with the phase change material in the water tank to perform comprehensive and efficient heat exchange. In the prior art, the brine or water entering the water tank is often directly through a pipe. The flow rate of the input into the water tank is large and concentrated, and the brine or water flows out quickly after flowing into the water tank, resulting in the inability of the brine or water to fully and evenly contact with the phase change material, which will easily lead to a decrease in the internal temp...

[0002] The phase change cold storage water tank using phase change material as the cold storage medium has the advantages of large energy storage per unit volume and high cold storage density. The brine or water in the water tank is fully and evenly contacted with the phase change material in the water tank to perform comprehensive and efficient heat exchange. In the prior art, the brine or water entering the water tank is often directly through a pipe. The flow rate of the input into the water tank is large and concentrated, and the brine or water flows out quickly after flowing into the water tank, resulting in the inability of the brine or water to fully and evenly contact with the phase change material, which will easily lead to a decrease in the internal temperature of the water tank. Inhomogeneous, the heat exchange rate of the phase change material cannot meet the actual requirements, which ultimately affects the cold storage and cooling effect of the water tank
