GRAVITY-ASSISTED HEAT PIPE GROUND COOLING SOURCE COLD STORAGE SYSTEM AND CHILLER SET

WIPO Patent Application WO/2017/045458

A1

A gravity-assisted heat pipe ground cooling source cold storage system and a chiller set. The cold storage system comprises a gravity-assisted heat pipe (5), a cold storage pool (4), a heat exchanging and cold condensing device (3), and a heat exchanger pipe. An inlet and outlet of the cold storage pool (4) 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 comprises a flow inlet pipe (2) and a flow return pipe (1) having a cross section comprising a first arc (11), second arc (12), third arc (13), and fourth arc (14) connected sequentially to one another. The second arc (12) and fourth arc (14) are S-shaped arcs. The first arc (11) has a radius exceeding that of the third arc (13), and centers of circles of the first arc (11) and third arc (13) are located at the cross section of the flow return pipe (1). The flow inlet pipe (2) comprises four pipes having circular cross sections and arranged around third arc (13).
