  • Patent number: 10295206
    Abstract: A gravity-assisted heat pipe ground cooling source cold storage system and a chiller set. The cold storage system includes a gravity-assisted heat pipe, a cold storage pool, a heat exchanging and cold condensing device, and a heat exchanger pipe. An inlet and outlet of the cold storage pool are parallel-connected to cold water pipes of a chiller set, and are connected or disconnected via control valves. The heat exchanger pipe is buried underground, and includes a flow inlet pipe and a flow return pipe having a cross section including a first arc, a second arc, a third arc, and a fourth arc. The second arc and the fourth arc are S-shaped arcs. The first arc has a radius exceeding that of the third arc, and centers of circles of the first arc and third arc are located at the cross section of the flow return pipe.
