[0001] The utility model relates to the technical field of heat pump exchanger connection, in particular to a dual-heat-source heat pump exchanger connection structure. Background Art

[0002] A dual-source heat pump exchanger is a device that uses two heat sources (such as air, water or ground) to transfer heat, and is used to improve the energy efficiency and flexibility of the heat pump system. This type of heat pump usually achieves heating or cooling effects by transferring heat between a low-temperature heat source and a high-temperature heat source. The heat source and the exchanger need to be transmitted through pipes. The installation and disassembly process of the pipes is cumbersome and requires the use of tools for manual operation, which increases the installation time and labor intensity. Secondly, different heat source bodies have different specifications and lengths, and ordinary mounting brackets have low flexibility, which causes great inconvenience to the installation and maintenance of the heat source body and reduces construction efficiency. In response to the above problems, the inventor proposed a dual-source heat pump exchanger connection structure to solve the above problems. Utility Model Content
