[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only partial structures related to the present invention are shown in the accompanying drawings, rather than the entire structure.

[0040] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the connection of the internal structures of two elements or the interaction relationship between two elements.

[0041] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0042] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0043] like Figure 1-Figure 3As shown, the present embodiment provides a heat pipe power generation device, which includes a shell 100, the shell 100 has a hollow structure, and the cross-sectional shape of the shell 100 can be circular, elliptical, square, rectangular, flat, any polygonal structure or a corrugated tube. In the present embodiment, the cross-sectional shape of the shell 100 is circular. Since the shell 100 is used to set up the structure, the shell 100 includes a main body 110 and two end covers 120. The two end covers 120 are respectively sealed to the two ends of the main body 110, thereby ensuring the sealing and safety of the heat pipe power generation device. Exemplarily, the end covers 120 and the main body 110 are detachably fixed to facilitate the disassembly and maintenance of the internal structure. The main body 110 here can be formed by stretching, which has high processing efficiency and low cost.

[0044] Furthermore, the material of the main body 110 and the end cover 120 is generally copper, aluminum, carbon steel, stainless steel, alloy steel, etc. In this embodiment, the material of the main body 110 and the end cover 120 is copper.

[0045] When in use, the shell 100 is filled with liquid, and the liquid here can be water, alcohol, etc. In this example, it is water. The shell 100 includes a first end and a second end, the first end is a heating end, and the second end is a cooling end. The heating end can be any heat source, so as to ensure the application range of the heat pipe power generation device. The cooling end can be water-cooled, air-cooled or natural convection, etc. During operation, the liquid near the first end can boil and generate steam under the action of the heat source, and the steam moves to the second end of the shell 100 and then cools and becomes liquid.

[0046] In one embodiment, the inner wall of the housing 100 is provided with a capillary groove extending axially along the housing 100, and the capillary groove can increase the lifting power of the capillary force in the housing 100, so that the liquid at the cooling end moves toward the first end under the action of the capillary groove. Specifically, the capillary groove is arranged on the inner wall of the main body 110 along the circumference of the main body 110, and the capillary groove and the main body 110 can be stretched and formed at the same time. Exemplarily, the cross-sectional shape of the capillary groove can be semicircular, square, etc.

[0047] Of course, in another embodiment, the inner wall of the housing 100 may also be a smooth surface, which simplifies the structure of the housing 100 and helps reduce processing costs.

[0048] Furthermore, the heat pipe power generation device also includes a capillary structure 200, which is embedded in the shell 100 along the axial direction of the shell 100. When the inner wall of the shell 100 is a smooth surface, the liquid at the second end flows to the first end through the action of the capillary structure 200. When the inner wall of the shell 100 is provided with a capillary groove, the capillary structure 200 and the capillary groove work together to make the liquid at the second end flow to the first end, which is conducive to increasing the capillary force and improving the power. Exemplarily, the capillary structure 200 is a copper powder sintered structure, a copper mesh, a copper cloth or a capillary.

[0049] like Figure 2 and Figure 3 As shown, the heat pipe power generation device also includes a power generation mechanism 300. The power generation mechanism 300 is fixed in the capillary structure 200 along the axial direction of the shell 100. The first end is heated to evaporate the liquid to generate steam, and the steam is converted into electrical energy through the power generation mechanism 300. At the same time, the steam moves to the second end and cools into liquid. The liquid at least flows back to the first end through the capillary structure 200. Through the power generation mechanism 300, the heat generated by the first end liquid being heated and converted into steam can be converted into electrical energy output. After the steam is cooled, it flows back to the first end from the second section again. Through such a continuous cycle, the power generation mechanism 300 is driven to continuously generate electricity, thereby realizing the continuous conversion of thermal energy into electrical energy. The heat pipe power generation device is suitable for any heat recovery and utilization site, such as base stations, steel industry, petrochemical industry, building materials industry, textile printing and dyeing industry, HVAC, hot water supply, etc. As an important energy-saving and environmental protection technology, the heat pipe power generation device can realize the recycling of energy, reduce energy consumption and environmental pollution, and reduce costs by effectively utilizing waste heat resources.

[0050] The output end of the power generation mechanism 300 passes through and protrudes from the end cover 120 located at the second end, so that the electric energy output by the power generation mechanism 300 can be connected to the external structure, thereby facilitating the utilization of the electric energy.

[0051] Specifically, the power generation mechanism 300 includes a kinetic energy unit 310 and a generator set 320. The kinetic energy unit 310 is coaxial with the housing 100 and arranged close to the first end, and the generator set 320 is connected to the output end of the kinetic energy unit 310. Since the first end is not heated, the kinetic energy unit 310 is arranged at the first end, and the steam generated after the first end is heated is used to drive the kinetic energy unit 310 to generate kinetic energy, and the kinetic energy is converted into electrical energy under the action of the generator set 320, thereby achieving the effect of converting heat energy recovery into electrical energy.

[0052] Optionally, the kinetic energy unit 310 is a steam turbine unit. The steam turbine unit structure can rotate under the drive of steam to generate kinetic energy without the need for other power drives, which is conducive to achieving energy-saving effects.

[0053] On this basis, the power generation mechanism 300 also includes an output component 330, which is arranged at one end of the generator set 320 away from the kinetic energy unit 310, and the far end of the output component 330 is arranged outside the second end of the shell 100. The output component 330 includes a wire and a protective layer, and the protective layer is sleeved on the wire, that is, the output component 330 is a structure for connecting the heat pipe power generation device with an external structure to realize the output and utilization of electric energy.

[0054] The protective layer is welded to the housing 100, which can not only play a fixing effect, but also help to ensure the vacuum degree inside the housing 100. The protective layer here is a heat-resistant insulating material, and the heat-resistant insulating material can be welded with copper into one body.

[0055] Furthermore, the output component 330 is a three-phase electric wire to ensure the safety and application range of the output electric energy.

[0056] In addition, the power generation mechanism 300 further includes a fixing frame 340 , and the kinetic energy unit 310 and the generator set 320 are arranged on the fixing frame 340 to ensure the safety and stability of the movement of the kinetic energy unit 310 .

[0057] The fixed frame 340 includes a first frame body 341 and a second frame body 342, and the first frame body 341 and the second frame body 342 are respectively mounted on the two ends of the central axis of the kinetic energy unit 310, and the first frame body 341 and the second frame body 342 are pivotally connected to the kinetic energy unit 310, and the first frame body 341 and the second frame body 342 are connected to the inner wall of the shell 100 and / or the capillary structure 200, thereby fixing the kinetic energy unit 310.

[0058] The fixing frame 340 further includes a third frame 343 , which is sleeved on the generator set 320 , and the third frame 343 is coaxially arranged with the first frame 341 to improve the coaxiality of the generator set 320 and the kinetic energy unit 310 , which is beneficial to ensure the working performance of the power generation mechanism 300 .

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
