[0018] Example 1

[0019] like Figures 1 to 4 As shown, the present invention proposes a heat dissipation mechanism, including a heat dissipation box 1, a sealing plate 3, and a heat dissipation mechanism; the heat dissipation box 1 has two sets of air inlets 104 at its input end, one of which is detachably equipped with a dustproof net 105; a mounting bracket 101 is installed on the top of the heat dissipation box 1, and the mounting bracket 101 has mounting holes, which facilitates the installation of the heat dissipation box 1 in a suitable position; the sealing plate 3 is detachably connected to the top of the heat dissipation box 1, and multiple sets of heat dissipation fins 301 are evenly installed on the bottom of the sealing plate 3, with the bottom of the heat dissipation fins 301 contacting the top of the UV-LED curing lamp body 2, and the bottom shape of the heat dissipation fins 301 being adjustable. To adapt to the top shape of the UV-LED curing lamp body 2 and improve heat transfer efficiency, multiple sets of through holes 302 are opened on the heat dissipation fins 301 to improve airflow. The heat dissipation mechanism consists of a fan box 4 connected to the output end of the heat dissipation box 1, two sets of air ducts 5 installed on the top of the sealing plate 3, and a connecting cover 503 connected to another set of air inlets 104. A cooling fan is installed inside the fan box 4. The output end of the fan box 4 is connected to one set of air ducts 5, and the output end of the other set of air ducts 5 is connected to the input end of the connecting cover 503. Multiple sets of heat dissipation pipes 501 are installed between the two sets of air ducts 5. The heat dissipation pipes 501 are made of the same material as the heat dissipation fins 301.

[0020] Furthermore, two sets of mounting seats 102 are symmetrically installed on the upper end of the inner wall of the heat sink 1. The sealing plate 3 is in contact with the inner wall of the heat sink 1. The sealing plate 3 is connected to the mounting seat 102 by bolts. A sealing gasket is provided at the connection between the sealing plate 3 and the heat sink 1 to improve the sealing performance of the connection.

[0021] Furthermore, a connecting cover 401 is provided between the air box 4 and the output end of the heat sink 1. The air inlet 104 is rectangular and corresponds to multiple sets of heat dissipation fins 301, so that the external heat dissipation air can enter the heat sink 1 and make uniform contact with the multiple sets of heat dissipation fins 301, absorb heat and discharge the heat sink 1 along the connecting cover 401.

[0022] Furthermore, an air outlet pipe 502 is installed at the output end of a set of air ducts 5 located away from the air box 4. The air outlet pipe 502 is connected to the connecting cover 503 and the air box 4 is connected to another set of air ducts 5 via flexible hoses. Both ends of the flexible hoses can be detached to facilitate the disassembly and maintenance of this mechanism.

[0023] In this embodiment, the sealing plate 3 is slid down along the inner wall of the heat sink 1 until the bottom of the sealing plate 3 abuts against the mounting base 102. The sealing plate 3 and the mounting base 102 are then fixedly connected by bolts. At this time, the bottom of the heat dissipation fins 301 contacts the top of the UV-LED curing lamp body 2, and a heat dissipation channel is formed between the multiple sets of heat dissipation fins 301, the sealing plate 3, and the UV-LED curing lamp body 2. Then, the air box 4 is connected to the air duct 5 through a flexible hose, and the air outlet duct 502 is connected to the connecting cover 503 through the flexible hose. The heat sink 1 is installed in a suitable position by bolts. The UV-LED curing lamp body 2 is started by the controller to carry out the curing work. The heat generated by the UV-LED curing lamp body 2 is absorbed by the multiple sets of heat dissipation fins 301 that are in contact with the top of the UV-LED curing lamp body 2. The cooling fan inside the air box 4 is started to draw the outside air along the inlet with the dustproof net 105 installed. Air is introduced through vent 104, and dust filter 105 filters impurities in the air to prevent them from entering the heat sink 1. The introduced air flows along the lower half of each heat dissipation channel, carrying the heat from the heat dissipation fins 301 out and into the air box 4 along the connecting cover 401. Then, it enters the first set of air ducts 5 along the hose. Inside the air duct 5, the hot air is divided into multiple sets of heat dissipation pipes 501. The heat dissipation pipes 501 absorb the heat of the hot air and dissipate it to the outside. After the hot air is cooled, it gathers along another set of air ducts 5 into the outlet pipe 502, and then flows back into the heat sink 1 through the hose and connecting cover 503 to blow the heat from the upper half of the heat dissipation fins 301. This blows the heat gathered in the upper half of each heat dissipation channel toward the connecting cover 401, accelerating the heat dissipation of each set of heat dissipation fins 301, thereby improving the heat dissipation efficiency of the UV-LED curing lamp body 2.

[0024] Example 2

[0025] like Figure 4 As shown, the heat dissipation mechanism proposed in this utility model, compared with Embodiment 1, further includes a uniform air distribution box 504 and a connecting pipe 505; the uniform air distribution box 504 is installed between the bottom ends of two sets of air ducts 5, and multiple sets of air outlets 506 are evenly opened on the uniform air distribution box 504, which are distributed below the outer peripheral surface of the heat dissipation pipe 501; one end of the connecting pipe 505 is connected to the air outlet pipe 502, and the other end of the connecting pipe 505 is connected to the input end of the uniform air distribution box 504.

[0026] In this embodiment, part of the cooled hot air that enters the air outlet duct 502 enters the heat dissipation box 1 along the connecting cover 2 503, and the other part enters the air distribution box 504 along the connecting pipe 505. Then, it is blown out of the heat dissipation pipe 501 by multiple sets of air outlets 506, which accelerates the heat dissipation of the heat dissipation pipe 501 and further improves the cooling efficiency of the hot air, thereby improving the heat dissipation efficiency of the heat dissipation fins 301.

[0027] Example 3

[0028] like Figures 1 to 3 As shown, the present invention proposes a UV-LED curing lamp, including a UV-LED curing lamp body 2 and the heat dissipation mechanism described in Embodiment 1 and Embodiment 2; the UV-LED curing lamp body 2 is installed at the bottom of the heat dissipation box 1, the bottom of the UV-LED curing lamp body 2 extends to the outside of the heat dissipation box 1, the top of the UV-LED curing lamp body 2 is provided with an ear for installation, the bottom of the heat dissipation box 1 is provided with an installation port 103 for installing the UV-LED curing lamp body 2, and the bottom of the heat dissipation fin 301 is in contact with the top of the UV-LED curing lamp body 2.

[0029] In this embodiment, the UV-LED curing lamp body 2 is inserted into the heat sink 1 so that its bottom end passes through the mounting port 103 until the ear on the UV-LED curing lamp body 2 abuts against the bottom end of the heat sink 1. The ear is then connected to the bottom end of the heat sink 1 by bolts, so that multiple sets of heat dissipation fins 301 can be installed. The bottom end of the heat dissipation fins 301 contacts the top end of the UV-LED curing lamp body 2, so that the heat generated by the UV-LED curing lamp body 2 during operation can be absorbed by the multiple sets of heat dissipation fins 301.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
