[0010] Preferably, the heat pipe further includes a flange, which is sealed and welded to the bottom of the pipe body, and the connector is located at the bottom of the flange.

[0011] Furthermore, the length of the vertical region of the first heat sink and the second heat sink is the same as the length of the tube body; The bottom of the flange is hexagonal, and the flange protrudes from the top surface of the heat pipe and connects to the bottom of the first heat sink and the second heat sink.

[0020] like Figures 1 to 3 As shown, a modular radiator includes several heating modules 1, and the side of each heating module 1 is provided with a mounting part 2, which is used to fix the radiator in the required position. The heating module 1 includes a heat sink assembly 11 and a heat pipe 12. The heat pipe 12 corresponds one-to-one with the heat sink assembly 11. The heat pipe 12 is vertically and detachably installed in the middle of the heat sink assembly 11. The heat sink assembly 11 includes a first heat sink 111 and a second heat sink 112 arranged opposite to each other. The first heat sink 111 and the second heat sink 112 are respectively provided with limiting parts 13 on their opposite surfaces. The limiting parts 13 are used to limit the heat pipe 12 to be relatively positioned between the first heat sink 111 and the second heat sink 112. The heat pipe 12 includes a pipe body 121, a heating tube 122 and a connector 123. The heating tube 122 is disposed inside the pipe body 121 and its end is fixedly connected to the connector 123. The connector 123 is disposed at the bottom of the pipe body 121. The pipe body 121 is in a vacuum state and is filled with refrigerant. The tube body 121 includes, from bottom to top, a heat absorption tube section 1211, an intermediate tube section 1212, and a heat dissipation tube section 1213. The heating tube 122 is disposed inside the heat absorption tube section 1211. The sides of the heat absorption tube section 1211 and the heat dissipation tube section 1213 are in contact with the first heat sink 111 and the second heat sink 112. The intermediate tube section 1212 does not contact the heat sink assembly 11.

[0021] To address the problems existing in the prior art, this utility model proposes a modular radiator. The modular radiator includes several heat dissipation fin groups 11 and heat pipes 12. Each heat pipe 12 includes a heat absorption section 1211, a middle section 1212, and a heat dissipation section 1213. In its initial state, the refrigerant within the heat pipe 12 is located in the heat absorption section 1211 due to gravity. When the heating element 122 is plugged in for heating, the refrigerant vaporizes upon heating, rises through the middle section 1212, reaches the heat dissipation section 1213, and contacts the wall of the heat dissipation section 1213, thus achieving heat dissipation. The heat is transferred and liquefied, flowing back to the heat-absorbing tube section 1211. The sides of the heat-absorbing tube section 1211 and the heat-dissipating tube section 1213 are in contact with the first heat sink 111 and the second heat sink 112, so heat can be quickly transferred to the heat sink assembly 11. The intermediate tube section 1212 does not contact the heat sink assembly 11, which ensures that the refrigerant can pass through the intermediate tube section 1212 after vaporization and will not dissipate heat in the intermediate tube section 1212, ensuring that the gas reaches the heat-dissipating tube section 1213. Based on the phase change heat transfer principle, the latent heat of phase change of the refrigerant can be used to quickly meet the heating demand and has high thermal efficiency. Meanwhile, the heat pipe 12 is vertically arranged in the middle of the heat sink assembly 11, which can effectively transfer heat to the heat sink assembly 11. Multiple heating modules 1 each complete an independent cycle of heating, phase change, heat transfer and heat dissipation, effectively avoiding the problem of near end being hot and far end being cold caused by using a single heat source for heating. It is not necessary to heat different heat pipes 12 in sequence, ensuring that the heating temperature of the radiator is uniform.

[0022] The heating module 1 has a mounting part 2 on its side. Specifically, the mounting part 2 has a through hole, and the mounting parts 2 can be connected to each other by a connecting rod, thereby connecting the same heating modules 1 one by one. During installation, the required number of heating modules 1 can be selected as needed and fixed by the mounting part 2 to obtain the heating area required for the corresponding space area, improving environmental adaptability. The heat pipe 12 corresponds one-to-one with the heat sink assembly 11. The heat pipe 12 is vertically arranged in the middle of the heat sink assembly 11. The heat pipe 12 is in a vacuum state and is equipped with a connector 123. The heating element 122 is connected to an external power source via the connector 123, causing it to heat up and thus achieving phase change heat transfer within the heating element 12. Each heating module 1 corresponds to one heating element 12, meaning the radiator as a whole is not an inseparable monolithic structure. When a heating module 1 malfunctions, it can be disassembled individually, and the heating element 12 can be removed from between the first and second radiator fins 111 and between the limiting parts 13. This allows for the replacement of the heating element 12 of a single heating module without disassembling the entire radiator, reducing maintenance costs and extending the radiator's lifespan. The individual configuration of the heating modules 1 also reduces assembly difficulty and improves production efficiency.

[0023] In summary, by setting up a separate heating module 1 and heating the heating pipe 122 of the heating module 1 through the connector 123, the purpose of heating is achieved through phase change heat transfer. Through the installation part 2, different numbers of heating modules 1 can be assembled, and the heating area of ​​the radiator can be adjusted according to the spatial requirements of different environments. Furthermore, the separately set heating module 1, each with a corresponding heat pipe 12, does not require complex pipe connections and is not an inseparable monolithic structure. It allows for maintenance of a specific heating module 1 without affecting the use of other heating modules 1, thus solving the problems of high maintenance difficulty and limited environmental adaptability of existing radiators.

[0024] Preferably, the tops of the first heat sink 111 and the second heat sink 112 are arc-shaped, the top arcs of the first heat sink 111 and the second heat sink 112 are concentric arcs, the first heat sink 111 and the second heat sink 112 are parallel to each other, and the top of the first heat sink 111 and the top of the second heat sink 112 are located on the same vertical line. The second heat sink 112 is located on the inner side of the arc, and the mounting part 2 is provided on the inner surface of the second heat sink 112.

[0025] Specifically, the tops of the first heat sink 111 and the second heat sink 112 are arc-shaped, which promotes gas convection, effectively increases the heat transfer area, and improves thermal efficiency. The second heat sink 112 is located on the inner side of the arc, and the tops of the first heat sink 111 and the second heat sink 112 are on the same vertical line, that is, the surface area of ​​the first heat sink 111 is larger than the surface area of ​​the second heat sink 112. The mounting part 2 is disposed on the inner surface of the second heat sink 112, so that after installation, the first heat sink 111 is away from the wall, that is, the first heat sink 111 can face the space that needs to be heated, has a larger heat dissipation area, ensures efficient air convection along the first heat sink 111, improves heat dissipation efficiency, and achieves heating more quickly.

[0026] Furthermore, a flow guide 113 is provided between the first heat sink 111 and the second heat sink 112. The flow guide 113 is located above the heat pipe 12, and the flow guide 113 is in contact with the top outer surface of the heat pipe 12. The flow guide 113 is connected to the arc-shaped top of the first heat sink 111 and the second heat sink 112. The cross-section of the guide plate 113 is cross-shaped. The guide plate 113 includes an arc-shaped component 1131 and a connecting component 1132. The top arc of the arc-shaped component 1131 is concentric with and parallel to the top arc of the first heat sink 111 and the second heat sink 112. The connecting component 1132 is perpendicular to the arc-shaped component 1131 and is connected to the first heat sink 111 and the second heat sink 112 respectively.

[0027] Specifically, the guide plate 113 connects the first heat sink 111 and the second heat sink 112, thereby achieving the integrity of the heat sink assembly 11, improving maintenance efficiency, and reducing the difficulty of disassembling the heat pipe 12.

[0028] Furthermore, the guide plate 113 is located above the heat pipe 12 and is in contact with the heat pipe 12. Based on the heat transfer between the first heat sink 111 and the second heat sink 112 and the heat pipe 12, the arrangement of the guide plate 113 further increases the heat dissipation area of ​​the heat sink assembly 11. At the same time, the cross section of the guide surface is "+", which promotes the heat to radiate outwards, expands the heat radiation range, makes the surrounding space more evenly heated, and improves human comfort.

[0029] Preferably, the length of the mounting portion 2 is the same as the width of the second heat sink 112; On a heating module 1, the number of mounting parts 2 is at least two, and the mounting parts 2 are disposed on the vertical surface of the second heat sink 112.

[0030] Specifically, the length of the mounting part 2 is the same as the width of the second heat sink 112, and the number of mounting parts 2 is at least two, to ensure that the heating module 1 can be stably installed in the required location, such as on a wall.

[0031] Preferably, there are two mounting parts 2, which are located at the upper and lower ends of the vertical surface of the second heat sink 112, respectively.

[0032] Preferably, the heat absorption tube section 1211 and the heat dissipation tube section 1213 have rectangular cross-sections, the intermediate tube section 1212 has a circular cross-section, the heat dissipation tube section 1213 has a larger cross-section than the intermediate tube section 1212, and the bottom surface of the heat dissipation tube section 1213 is larger than the bottom surface of the intermediate tube section 1212 to form an assembly surface 1214. The limiting part 13 is a deformable elastic buckle. When the heat pipe 12 is installed in the middle of the heat sink assembly 11, the elastic buckle contacts the mounting surface 1214.

[0033] Specifically, the heat absorption tube section 1211 and the heat dissipation tube section 1213 have rectangular cross sections, which can fit well with the first heat sink 111 and the second heat sink 112 to achieve heat transfer. The intermediate tube section 1212 has a circular cross section and does not contact the heat sink assembly 11, which can ensure that the gas vaporized by the refrigerant can stably pass through the intermediate tube section 1212 to reach the heat dissipation tube section 1213 to achieve heat transfer.

[0034] In addition, the structure of the tube body 121 can be adapted to the limiting part 13, making it easy to disassemble and clean the heat sink assembly 11.

[0035] Specifically, a portion of the side of the limiting part 13 is fixedly connected to the first heat sink 111 and the second heat sink 112. The bottom of the limiting part 13, which is used to lock the heat pipe segment 1213, can deform, which can limit the relative position of the heat pipe 12 and the heat sink group 11 to a certain extent.

[0036] Preferably, there are four limiting parts 13, which are respectively provided in pairs on the first heat sink 111 and the second heat sink 112, and are in contact with the four corners of the mounting surface 1214.

[0037] Preferably, the heat pipe 12 further includes a flange 124, which is sealed and welded to the bottom of the pipe body 121, and the connector 123 is disposed at the bottom of the flange 124.

[0038] Specifically, the flange 124 facilitates the creation of a vacuum state inside the heat pipe 12 while ensuring a stable connection between the heating pipe 122 and the connector 123.

[0039] Furthermore, the length of the vertical region of the first heat sink 111 and the second heat sink 112 is the same as the length of the tube body 121; The bottom of the flange 124 is hexagonal, and the flange 124 protrudes from the top surface of the heat pipe 12 and connects with the bottom of the first heat sink 111 and the second heat sink 112.

[0040] Specifically, the shape of the flange 124 matches the limiting part 13 to ensure that the heat pipe 12 is located in the required position of the heat sink assembly 11. At the same time, the radial force of the hexagonal flange 124 is more uniform, effectively avoiding the situation where the heat pipe 12 has low sealing reliability due to uneven local pressure.

[0041] It is worth noting that the refrigerant is a mixture of water and ethanol.

[0042] Specifically, water has a higher latent heat of phase change than ethanol. After mixing, it can retain most of the high latent heat characteristics of water. At the same time, the refrigerant can transfer more heat per unit mass. Ethanol reduces the viscosity of water, making the phase change resistance of the refrigerant in the heat pipe 12 smaller and optimizing the flow circulation in the heat pipe 12.

[0043] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
