Description

Technical Field

[0002] High-efficiency heat exchangers in heat pump systems are core components ensuring system energy efficiency and are widely used in district heating, industrial processes, and commercial buildings. Traditional high-efficiency heat pump tanks typically employ a single-inlet, single-outlet piping design, with multiple units connected in parallel via external piping to meet varying load demands. However, this design has significant shortcomings in terms of space utilization, hydraulic balance, and operational flexibility, necessitating optimization and improvement.

[0003] Existing high-efficiency tanks mainly consist of an outer cylinder, an internal spiral coil, and a single-point flange interface, with the inlet and outlet ports mostly located on the same side or adjacent to each other on the cylinder. When multiple units are connected in parallel, each unit needs to be independently connected to the main supply and return water pipelines through complex piping branches, resulting in a cumbersome system structure and wasted installation space. In addition, traditional designs lack standardized quick connection and shutdown solutions, making it difficult to adapt to frequent start-ups, shutdowns, or capacity expansion requirements.
