HEAT PIPE AND GEOTHERMAL ENERGY COLLECTION DEVICE

A heat pipe and a geothermal energy collecting device are provided. The heat pipe includes a sealing member (120), a first pipe body (110), first heat transfer members (130), and second heat transfer members (140); the sealing member (120) is provided with channels (121); one end of the first pipe body (110) has an opening (111), and an other end of the first pipe body is sealed by the sealing member (120), which has a first chamber (112) for accommodating a heat transfer working medium; the first heat transfer members (130) are connected to the sealing member (120) and located at one side of the sealing member (120), each of the first heat transfer members (130) has a first cavity; and the second heat transfer members (140) are connected to the sealing member (120) and located at an other side of the sealing member (120), each of second heat transfer members (140) 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 (121), such that a second chamber (113) for accommodating a heat-transfer working medium is defined jointly by the second heat transfer members (140) and the corresponding one of the first heat transfer members (140), and the second chamber (113) and the first chamber (112) are spaced apart. Heat transfer can be performed between the adjacent heat pipes (110) via interstage heat pipes formed by the first heat transfer member (130) and the second heat transfer member (140). The interstage heat pipes have a low heat resistance, and is enabled to extend into the first chamber (112) to be fully in contact with the steam, thereby facilitating to improve heat exchange efficiency.
