AI Technical Summary
Existing centralized cold and heat source equipment is prone to pipe rupture and leakage in cold regions due to freezing expansion, and existing antifreeze devices are energy-intensive and cannot recycle heat.
A circulating pump drives a heat transfer hose to transfer heat to the heat storage block. When the ambient temperature is low, the heat transfer medium inside the serpentine tube absorbs the heat and dissipates it into the equipment cavity. In summer, heat is dissipated through an electric telescopic rod and fan blade system, realizing the recycling of heat.
It effectively prevents equipment from freezing, reduces energy consumption, improves heat dissipation efficiency, and prevents dust accumulation caused by exposed equipment.
