Technical Field

[0001] The present application relates to the field of heat pipe type double-glass high temperature and high efficiency PVT components, and in particular to a heat pipe type double-glass high temperature and high efficiency PVT component. Background Art

[0002] At present, the world is facing a shortage of energy. Photovoltaic power generation, as one of the renewable energy sources, has become an important part of the future energy field. Photovoltaic power generation components are usually installed outdoors and are affected by the ambient temperature when working. When the temperature is low, the performance of photovoltaic components declines, the photoelectric conversion efficiency decreases, and it is easy to cause damage to the photovoltaic components.

[0003] The existing solution is to install heat pipes inside the photovoltaic modules to exchange heat inside the photovoltaic modules. The heat pipes are filled with heat-conducting media, usually liquid condensing agents such as water and ethylene glycol. Flange connections are usually used at the heat pipe joints, and the heat pipes are connected together through flanges and sealing gaskets.

[0004] The above-mentioned prior art solutions have the following defects: multiple bolts are required for tightening during the installation process, and the process of repeatedly installing multiple pairs of bolts and nuts is relatively complicated. A large number of repeated actions over a long period of time can easily cause workers to make improper installations, resulting in loose connections or even leakage. Utility Model Content

[0005] In order to simplify the heat pipe installation process, enhance the pipeline sealing and improve the thermal efficiency, the present application provides a heat pipe type double-glass high-temperature and high-efficiency PVT component.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A heat pipe type double-glass high-temperature and high-efficiency PVT component comprises a vacuum heat pipe, a lock nut and a main heat pipe, a baffle being welded on the outer wall of the vacuum heat pipe, the lock nut being movably sleeved on the outside of the vacuum heat pipe, and the lock nut being located on the side of the baffle away from the main heat pipe, the inner wall of the lock nut being away from the baffle is processed to form a sleeve, a branch heat pipe is fixedly provided on the outer wall of the main heat pipe, the branch heat pipe is sleeved and connected with the vacuum heat pipe, a wire head is fixedly connected to one end of the branch heat pipe away from the main heat pipe, after the branch heat pipe is sleeved on the outer wall of the vacuum heat pipe, the wire head is fitted with the baffle, the rotating lock nut is threadedly connected with the wire head, and the wire head and the lock nut clamp the baffle.

[0008] By adopting the above technical solution, during installation, the baffle will limit the length of the vacuum heat pipe inserted into the heat distribution pipe, control the distance between the vacuum heat pipe and the inner wall of the main heat pipe, so that the end of the vacuum heat pipe can contact the heat transfer medium, and can also prevent the vacuum heat pipe from contacting the inner wall of the main heat pipe, thereby reducing the liquid flow rate on the surface of the vacuum heat pipe close to the main heat pipe. The ferrule on the inner wall of the lock nut can limit the baffle, so that the thread head fits the baffle, thereby enhancing the sealing of the pipeline and simplifying the installation process.

[0009] Optionally, a section of the vacuum heat pipe is set as a heating section, the diameter of the heating section is larger than the diameter of the vacuum heat pipe, and after the heating section is inserted into the heat distribution pipe, the outer wall of the heating section fits with the inner wall of the heat distribution pipe.

[0010] By adopting the above technical solution, when the vacuum heat pipe exchanges heat with the heat-conducting medium in the main heat pipe, the heating section with a larger diameter can effectively improve the heat exchange efficiency of the heat-conducting medium in the main heat pipe to the vacuum heat pipe, and the heating section fits the branch heat pipe to enhance the sealing effect of the pipeline.

[0011] Optionally, the heating section is inserted into one end of the main heat pipe and processed into a cone shape.

[0012] By adopting the above technical solution, when the vacuum heat pipe needs to be replaced or overhauled, the conical end of the heating section can be easily inserted into the heat distribution pipe, which is convenient for installation and effectively reduces damage caused by improper operation during installation. The conical end of the heating section has greater structural strength than the heating section with a flat end face, which can reduce the deformation of the heating section and increase the contact area between the vacuum heat pipe and the heat transfer medium in the main heat pipe, thereby improving the thermal efficiency of the heat pipe.

[0013] Optionally, a gasket is provided on the inner wall of the lock nut.

[0014] By adopting the above technical solution, after the lock nut is tightened, the washer is stuck between the thread head and the lock nut, increasing the friction between the thread head and the lock nut, which can effectively reduce the possibility of the lock nut loosening and falling off, and can also effectively improve the airtightness of the heat pipe and ensure the stability of the heat pipe operation.

[0015] Optionally, a sealing gasket is embedded in and clamped on the inner wall of the lock nut, and the sealing gasket is annular.

[0016] By adopting the above technical solution, after the lock nut is tightened, the sealing gasket is tightly clamped between the lock nut and the baffle, thereby increasing the airtightness of the pipeline and effectively reducing the risk of leakage of the heat transfer medium inside the heat pipe.

[0017] Optionally, the lock nut is processed on a side close to the baffle to form an inwardly inclined slope.

[0018] By adopting the above technical solution, when the lock nut is rotated, the inclined surface of the inner wall close to the baffle side facilitates the alignment of the threads of the inner wall of the lock nut with the threads of the outer wall of the thread head, which is convenient for installation.

[0019] Optionally, an elastic part is sleeved and fixedly connected to the outer wall of the heat distribution pipe, and the elastic part is located on the side of the wire head close to the main heat pipe. The elastic part is an elastic part made of metal spring sheet. The elastic part is fixedly connected to one end of a limiting column close to the wire head. A groove is provided on the lock nut close to the wire head. When the lock nut is fully connected to the wire head, the limiting column is stuck in the groove.

[0020] By adopting the above technical solution, after the lock nut is tightened and the limiting column is stuck in the groove, the limiting column can prevent the lock nut from rotating, effectively reducing the risk caused by the loosening of the lock nut, and making it easier for maintenance personnel to judge the tightening status of the lock nut during maintenance.

[0021] Optionally, the vacuum heat pipe is a vacuum heat pipe made of copper.

[0022] By adopting the above technical solution, industrial production is facilitated, and the manufactured vacuum heat pipe has better thermal conductivity, can withstand high temperatures during operation, and is not prone to deformation and damage.

[0023] Optionally, the gasket is made of nylon.

[0024] By adopting the above technical solution, the manufactured gasket can maintain stable performance at high temperature, the lock nut is subjected to balanced force, and the reliability of the threaded connection is improved.

[0025] In summary, this application has the following technical effects:

[0026] 1. By setting up the baffle, vacuum heat pipe, lock nut and main heat pipe, the baffle will limit the length of the vacuum heat pipe inserted into the sub-heat pipe during installation, control the distance between the vacuum heat pipe and the inner wall of the main heat pipe, so that the end of the vacuum heat pipe can contact the heat transfer medium, and can also prevent the vacuum heat pipe from contacting the inner wall of the main heat pipe, reduce the liquid flow rate on the surface of the vacuum heat pipe close to the main heat pipe, and the ferrule on the inner wall of the lock nut can limit the baffle, so that the wire head fits the baffle, enhances the sealing of the pipeline, and simplifies the installation process;

[0027] 2. By setting a gasket, the friction between the thread head and the lock nut is increased, which can effectively reduce the possibility of the lock nut loosening and falling off, and can also effectively improve the airtightness of the heat pipe and ensure the stability of the heat pipe operation;

[0028] 3. By providing an elastic member and a limit column, the limit column can be stuck in the groove provided on the lock nut, thereby increasing the resistance to the rotation of the lock nut, effectively reducing the risk caused by the loosening of the lock nut, and facilitating maintenance personnel to judge the fastening state of the lock nut during maintenance.

[0034] The present application is further described in detail below in conjunction with the accompanying drawings.

[0035] Embodiment 1

[0036] The present application embodiment discloses a heat pipe type double glass high temperature and high efficiency PVT component, referring to Figure 1 and Figure 2 , which includes a PVT component 1, a vacuum heat pipe 2, a lock nut 3 and a main heat pipe 4. Eight vacuum heat pipes 2 are inserted into the PVT component 1. The length direction of the eight vacuum heat pipes 2 is parallel to the length direction of the PVT component 1. One end of the vacuum heat pipe 2 is located inside the PVT component 1, and the other end is located outside the PVT component 1. The vacuum heat pipe 2 is located outside the PVT component 1. A baffle 22 is welded on a section of the outer wall. Eight lock nuts 3 are movably sleeved on the outside of the vacuum heat pipe 2, and the lock nut 3 is located between the baffle 22 and the PVT component 1. The inner wall of the lock nut 3 close to the PVT component 1 is processed to form a sleeve for fixing the baffle 22. The main heat pipe 4 is connected to the end of the vacuum heat pipe 2 extending out of the PVT component 1. Eight branch heat pipes 41 are fixedly arranged on the outer wall along the length direction of the main heat pipe 4. The eight branch heat pipes 41 correspond to the eight vacuum heat pipes 2 one by one and are sleeved and connected. The ends of the heat distribution pipes 41 away from the main heat pipe 4 are welded with thread heads 42 . After the eight heat distribution pipes 41 are respectively sleeved on the outer wall of the vacuum heat pipe 2 , the thread heads 42 are fitted to the opposite side of the baffle 22 .

[0037] When installing the heat pipe type double-glass high-temperature and high-efficiency PVT component, the lock nut 3 is put on a section of the eight vacuum heat pipes 2 that is not welded with the baffle 22 and inserted into the PVT component 1, and the other section is inserted into the heat distribution pipe 41. The baffle 22 will limit the length of the vacuum heat pipe 2 inserted into the heat distribution pipe 41, and control the distance between the vacuum heat pipe 2 and the inner wall of the main heat pipe 4, so that the end of the vacuum heat pipe 2 can contact the heat-conducting medium while preventing the vacuum heat pipe 2 from contacting the inner wall of the main heat pipe 4, reducing the liquid flow rate on the surface of the vacuum heat pipe 2 close to the main heat pipe 4, connecting the lock nut 3 with the thread head 42, and the sleeve on the inner wall of the lock nut 3 limits the baffle 22, so that the pipeline has good sealing performance and the installation process is simple.

[0038] Reference Figure 2 A section of the vacuum heat pipe 2 inserted into the heat distribution pipe 41 is set as the heating section 21. The diameter of the heating section 21 is larger than the diameter of a section of the vacuum heat pipe 2 inserted into the PVT component 1. After the heating section 21 is inserted into the heat distribution pipe 41, the outer wall of the heating section 21 fits with the inner wall of the heat distribution pipe 41.

[0039] When using the present heat pipe PVT assembly, the heating section 21 with a larger diameter can effectively increase the contact area with the heat-conducting medium in the main heat pipe 4, thereby improving the heat exchange efficiency of the heat-conducting medium in the main heat pipe 4 to the vacuum heat pipe 2. The heating section 21 fits closely with the heat distribution pipe 41, thereby enhancing the sealing effect of the pipeline.

[0040] Reference Figure 2 The heating section 21 is inserted into one end of the main heat pipe 4 and processed into a cone shape. When the vacuum heat pipe 2 needs to be replaced or repaired, the conical end of the heating section 21 is convenient for inserting into the heat pipe 41, which is convenient for installation and effectively reduces damage caused by improper operation during installation. The conical end of the heating section 21 has greater structural strength than the heating section 21 with a flat end surface. When the temperature of the heat transfer medium in the main heat pipe 4 is high, the deformation of the heating section 21 can be reduced, and the contact area between the vacuum heat pipe 2 and the heat transfer medium in the main heat pipe 4 can be increased, thereby improving the thermal efficiency of the heat pipe.

[0041] Reference Figure 2 A gasket 31 is embedded in the inner wall of the lock nut 3 near the PVT assembly 1. After the lock nut 3 is tightened, the gasket 31 is stuck between the thread head 42 and the lock nut 3, increasing the friction between the thread head 42 and the lock nut 3, which can effectively reduce the possibility of the lock nut 3 loosening and falling off, and can also effectively improve the airtightness of the heat pipe and ensure the stability of the heat pipe.

[0042] Reference Figure 2 The lock nut 3 is processed to form an inwardly inclined inclined surface on one side close to the baffle 22. When the lock nut 3 is rotated, the inclined surface close to the inner wall of the baffle 22 facilitates the thread of the inner wall of the lock nut 3 to align with the thread of the outer wall of the thread head 42, reducing the difficulty of installation.

[0043] The vacuum heat pipe 2 is made of copper. The vacuum heat pipe 2 made of copper has strong plasticity, is convenient for industrial production, and has strong thermal conductivity, so that the vacuum heat pipe 2 made of copper has better thermal conductivity, can withstand high temperature and is not easy to deform and damage during work.

[0044] The washer 31 is made of nylon material. The washer 31 made of nylon material can maintain stable performance at high temperatures, play a buffering role between the lock nut 3 and the thread head 42, balance the force of the lock nut 3, and improve the reliability of the threaded connection.

[0045] Embodiment 2

[0046] The difference between this embodiment and the first embodiment is that:

[0047] Reference Figure 3A heat pipe type double-glass high temperature and high efficiency PVT component also includes an elastic member 43 and a limit column 44. The elastic member 43 is in a circular ring shape. The elastic member 43 is sleeved and welded to the outer wall of the heat distribution pipe 41, and is located on the side of the wire head 42 close to the main heat pipe 4. The elastic member 43 and the end face of the wire head 42 facing the heat distribution pipe 41 are in contact. The elastic member 43 is a circular metal sheet made by stamping metal springs. When the outer edge of the circular ring is subjected to external force from the vertical direction, it will be deformed, and the circular ring shape will be restored after the external force is removed.

[0048] Reference Figure 4 One end of the limiting column 44 is fixed to the side of the elastic member 43 close to the thread head 42, and the end of the limiting column 44 away from the elastic member 43 is spherical. There are six limiting columns 44, which are evenly arranged along the outer diameter edge of the elastic member 43. Six grooves are opened on the side of the lock nut 3 close to the thread head 42. When the lock nut 3 is fully connected to the thread head 42, the six limiting columns 44 are respectively clamped in the six limiting grooves.

[0049] When the lock nut 3 is rotated, the lock nut 3 rotates along the thread head 42 and gradually approaches the limit column 44. When the lock nut 3 contacts the limit column 44, the elastic member 43 is pushed up toward the main heat pipe 41. The lock nut 3 is continuously tightened until the lock nut 3 is tightened and the limit column 44 is stuck in the groove. The limit column 44 can prevent the lock nut 3 from rotating, effectively reducing the risk caused by the loosening of the lock nut 3, and facilitating maintenance personnel to judge the tightening state of the lock nut 3 during maintenance.

[0050] Reference Figure 4 A heat pipe type double-glass high temperature and high efficiency PVT component also includes a sealing gasket 32, which is embedded in and clamped on a section of the inner wall of the lock nut 3 close to the PVT component 1, and is located on the side of the clamping sleeve formed by the inner wall of the lock nut 3 close to the baffle 22, and the sealing gasket 32 ​​is annular.

[0051] After the lock nut 3 is tightened, the sealing gasket 32 ​​is tightly clamped between the lock nut 3 and the baffle 22, thereby increasing the airtightness of the pipeline and effectively reducing the risk of leakage of the heat transfer medium inside the heat pipe.

[0052] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed. However, as long as it is within the scope of the claims of the present application, it shall be protected by the patent law.
