1. A geothermal energy collecting device, comprising:
a geothermal energy collecting part comprising ones of a plurality of heat pipes, wherein each of the plurality of the heat pipes comprises:
a sealing member provided with channels;
a first pipe body, wherein one end of the first pipe body has an opening and an other end of the first pipe body is sealed by the sealing member, the first pipe body has a first chamber for accommodating a heat transfer working medium;
first heat transfer members which are connected to the sealing member and located at one side of the sealing member, wherein each of the first heat transfer members has a first cavity; and
second heat transfer members which are connected to the sealing member and located at an other side of the sealing member, wherein each of the second heat transfer members has a second cavity configured to communicate with the first cavity of a corresponding one of the first heat transfer members via a respective one of the channels, such that a second chamber for accommodating a second heat-transfer working medium is defined jointly by the second heat transfer member and the corresponding one of the first heat transfer members, and the second chamber and the first chamber are spaced apart,
wherein one end of one of every adjacent two of the ones of the plurality of heat pipes which has the opening is connected to one end, which has the sealing member, of an other one of the every adjacent two of the ones of the plurality of heat pipes;
a heat exchange part comprising a heat exchanger, wherein the heat exchanger is configured for transferring heat collected by the geothermal energy collecting part;
wherein a head end of the first pipe body is sealed by the sealing member, the first heat transfer members are located at an upper side of the sealing member, and the second heat transfer members are located at a lower side of the sealing member along a heat transfer direction;
the heat pipe further comprises flow guiding members, each of the second heat transfer members is connected with ones of the flow guiding members, one end of each of the ones of the flow guiding members is connected to the second heat transfer member, and an other end of the flow guiding member extends downwards and is connected to an inner wall of the first pipe body.
