AI Technical Summary
Existing volumetric heat exchangers are mostly single-heat-source heating structures, which cannot effectively integrate multiple heat sources, resulting in low heat source utilization and uneven heating, affecting the temperature balance of domestic hot water and system efficiency.
A multi-heat-source volumetric heat exchanger is designed, which adopts a heating tube bundle and flow-dividing baffle structure to allow multiple heat sources to be connected. The flow-dividing baffle evenly disperses the water flow, and combined with the three-dimensional spiral arrangement of the porous heating tube bundle, it achieves efficient heat transfer and uniform distribution.
It improves energy utilization, reduces heat waste, ensures consistent hot water temperature and stable system operation, and enhances user comfort and system efficiency.
