[0026] According to an embodiment of the present invention, a glass heat pipe spiral coil type pressure-bearing collector is provided.

[0027] Embodiment 1;

[0028] As Figures 1-6 shown, the glass heat pipe spiral coil type pressure-bearing collector according to an embodiment of the present invention includes a heat pipe structure 1, a heat collection structure 6 is installed in the heat pipe structure 1, a buffer structure 5 is provided at the bottom end of the heat collection structure 6, a connecting pipe 2 is connected to the heat pipe structure 1, a joint structure 3 is docked on the connecting pipe 2, and an adjustment structure 4 is provided on one side of the connecting pipe 2.

[0029] Inside the heat pipe structure 1, solar energy is converted through the heat collection structure 6. The heat is transferred through the joint structure 3 to connect the heat exchange pipes. The buffer structure 5 can buffer the heat collection structure 6 to improve its safety in use. The adjustment structure 4 can adjust the vacuum to maintain the vacuum degree of the vacuum layer 106.

[0030] The heat pipe structure 1 includes a glass tube 101, a sealing cap 102, a first pair of connectors 103, a cold water pipe 104, a hot water pipe 105, and a vacuum layer 106. A sealing cap 102 is hermetically connected to the glass tube 101. A first pair of connectors 103 are provided on the sealing cap 102. A cold water pipe 104 is provided on one side of the sealing cap 102 at the first pair of connectors 103. A hot water pipe 105 is provided on one side of the cold water pipe 104. A vacuum layer 106 is provided inside the glass tube 101. The hot water pipes 105 are connected through a connecting pipe 2. The cold water pipes 104 are connected through a connecting pipe 2.

[0031] A vacuum layer 106 is formed between the glass interlayers of the glass tube 101. The cold water pipe 104 is connected to the inlet of the spiral heat pipe in the spiral tube channel 603 to conduct the working fluid after heat exchange cooling into the spiral heat pipe. The working fluid after absorbing heat in the spiral heat pipe is transferred to the heat exchange pipe in the water tank through the hot water pipe 105 connected to the outlet of the spiral heat pipe to heat the hot water in the water tank. The vacuum layer 106 is communicated with the vacuum tube 401. The sealing cap 102 plugs the opening of the glass tube 101 to prevent pollution of the glass inner wall.

[0032] The joint structure 3 includes a docking plug 301, a heat pipe adapter 302, and a cold pipe docking head 303. The docking plug 301 is connected to the port of the connecting pipe 2 where the cold water pipe 104 and the hot water pipe 105 are connected. A heat pipe adapter 302 and a cold pipe docking head 303 are respectively provided on the docking plug 301. The heat pipe adapter 302 has four adapters. One end of the heat pipe adapter 302 is communicated with the connecting pipe 2 of the hot water pipe 105.

One end of the cold pipe docking head 303 is communicated with the connecting pipe 2 of the cold water pipe 104. The other end of the cold pipe docking head 303 is communicated with the outlet of the circulation pump.

[0033] The heat pipe adapter 302 of the joint structure 3 is connected to the heat exchange pipe, which is mainly used to transfer the heat of the working fluid to the water in the water tank to increase the water temperature in the water tank. The working fluid after heat exchange will be transferred to the cold water pipe 104 under the transmission pressure of the circulation pump to complete the circulation of the working fluid. At the same time, the function of the circulation pump can prevent the working fluid from solidifying in a low-temperature environment and maintain the fluidity of the working fluid. It can also stop the work of the circulation pump in a high-temperature situation, so that the working fluid can perform a self-circulation without power when the solar energy is sufficient.

[0034] The adjustment structure 4 includes a vacuum tube 401, an adjustment tube 402, and a drive motor 403. An adjustment tube 402 is connected to the vacuum tube 401. A threaded block is drivingly connected inside the adjustment tube 402. A bidirectional threaded rod is drivingly connected inside the threaded block. One end of the bidirectional threaded rod is connected to a drive motor 403. The drive motor 403 is fixedly installed on the vacuum tube 401. The threaded block is in a sliding sealing and limiting connection with the inner wall of the adjustment tube 402. Oil seals are provided in the internal threaded holes of the threaded block and the contact surface with the adjustment tube 402.

[0035] The drive motor 403 can drive the bidirectional threaded rod so that the bidirectional threaded rod can drive the two threaded blocks inside the adjustment tube 402 to move towards each other. Since the threaded block is provided with an oil seal, sealed transmission can be performed, enabling the air pressure inside the adjustment tube 402 and the vacuum tube 401 to be adjusted during the transmission process. When the two threaded blocks move away from each other, the internal vacuum space is increased, thereby improving the vacuum degree. Vacuum degree adjustment can be carried out after the vacuum degree of the vacuum layer 106 drops to maintain a good vacuum degree.

[0036] The buffer structure 5 includes a buffer pad 501 and a buffer spring 502. A heat collection groove is provided at the center of the glass tube 101. The buffer pad 501 is installed at the bottom end of the heat collection groove. The buffer spring 502 is provided on the buffer pad 501. A buffer spacer is provided on the buffer spring 502. A heat collection structure 6 is provided on the buffer spacer.

[0037] The buffer pad 501, the buffer spring 502, and the buffer spacer of the buffer structure 5 can well support the heat collection tube 601 and prevent damage to the bottom of the glass tube 101.

[0038] The heat collection structure 6 includes a heat collection tube 601, heat collection fins 602, a spiral tube channel 603, and a penetration groove 604. Heat collection fins 602 are provided on the heat collection tube 601. A spiral tube channel 603 is provided inside the heat collection tube 601. A penetration groove 604 is provided at the center of the heat collection tube 601.

[0039] By providing the heat collection fins 602 on the heat collection tube 601, the light energy receiving area can be increased. Selective absorption films are provided on the surfaces of the heat collection tube 601 and the heat collection fins 602, which can convert light energy into heat energy and transfer the energy to the spiral heat pipe inside the spiral tube channel 603 through the heat collection tube 601. The penetration groove 604 is used for penetrating the rising channel. The cold water pipe 104 is connected to the top interface of the spiral heat pipe of the heat collection tube 601. The working fluid can fall into the spiral heat pipe in the cold water pipe 104 for endothermic phase change, and after endothermic absorption, it enters the hot water pipe 105 through the rising channel connected to the bottom end of the spiral heat pipe, completing a non-powered self-circulation.

[0040] To facilitate the understanding of the above technical solution of the present utility model, the working principle or operation method of the present utility model in the actual process will be described in detail below.

[0041] In summary, by means of the above technical solution of the present utility model, the heat pipe structure 1 internally converts the solar energy through the heat collection structure 6, connects the heat exchange pipe through the joint structure 3 to transfer heat energy, the buffer structure 5 can buffer the heat collection structure 6 to improve its use safety, and the adjustment structure 4 can adjust the vacuum to maintain the vacuum degree of the vacuum layer 106. A vacuum layer 106 is formed between the glass interlayers of the glass tube 101. The cold water pipe 104 is connected to the inlet of the spiral heat pipe in the spiral pipe channel 603 for conducting the working medium after heat exchange cooling into the spiral heat pipe. The working medium after absorbing heat in the spiral heat pipe is transferred to the heat exchange pipe in the water tank through the hot water pipe 105 connected to the spiral heat pipe outlet to heat the hot water in the water tank. The vacuum layer 106 is communicated with the vacuum tube 401, and the cover 102 plugs the opening of the glass tube 101 to prevent pollution of the glass inner wall. The heat pipe tap 302 of the joint structure 3 is connected to the heat exchange pipe, and the heat exchange pipe is mainly used to transfer the heat of the working medium to the water in the water tank to increase the water temperature of the water tank. The working medium after heat exchange will be transferred to the cold water pipe 104 under the transmission pressure of the circulation pump after cooling to complete the circulation of the working medium. At the same time, the function of the circulation pump can prevent the working medium from solidifying in a low-temperature environment and maintain the fluidity of the working medium. It can also stop the work of the circulation pump in a high-temperature situation, so that the working medium can perform a power-free self-circulation in the case of sufficient solar energy. The driving motor 403 can drive the bidirectional threaded rod, so that the bidirectional threaded rod can drive the two threaded blocks in the adjusting pipe 402 to move towards each other. Since the threaded block is provided with an oil seal, sealed transmission can be performed, so that the air pressure in the adjusting pipe 402 and the vacuum tube 401 can be adjusted during the transmission process. When the two threaded blocks move away from each other, the internal vacuum space is increased, thereby increasing the vacuum degree, and the vacuum degree can be adjusted to maintain a good vacuum degree after the vacuum degree of the vacuum layer 106 drops. The heat collection tube 601 can increase the light energy receiving area by opening heat collection fins 602. The surfaces of the heat collection tube 601 and the heat collection fins 602 are provided with selective absorption films, which can convert light energy into heat energy, and transfer the energy to the spiral heat pipe in the spiral pipe channel 603 through the heat collection tube 601. The through-hole 604 is used for passing through the rising channel. The cold water pipe 104 is connected to the top interface of the spiral heat pipe of the heat collection tube 601. The working medium can fall into the spiral heat pipe in the cold water pipe 104 for endothermic phase change, and enter the hot water pipe 105 through the rising channel connected to the bottom end of the spiral heat pipe after absorbing heat to complete the power-free self-circulation.

[0042] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
