[0024] A heat-conducting column 8 having heat dissipation fins 9 and sealingly matched with the opening of the storage cavity 71;

[0025] A refrigerator 10 having a cold conduction plate 11, wherein the cold conduction plate 11 is inserted into the storage cavity 71 and is located in the cold conduction medium;

The cooling fan 13 is located on the inner side of the exhaust hole, and the air inlet end of the cooling fan 13 is located in the air guide cavity 72 .

[0027] In this embodiment, when the LED lamp bead is lit, high heat is generated. The heat is transferred along the heat conducting rod 6 to the heat conducting column 8 and the heat dissipation fins 9. The heat dissipation fins 9 quickly cool down after heat exchange with the low-temperature cooling medium. Since the temperature of the cooling medium increases, the refrigerator 10 cools at this time, and the low temperature is transferred to the cooling medium through the cooling plate 11, and the heat dissipation end of the refrigerator 10 itself generates heat. The heat is cooled and dissipated by the cooling fan 13 by drawing air from the outside. The utility model combines water cooling and air cooling in one, has higher heat dissipation efficiency, and its installation and disassembly operations are simple and convenient.

[0028] Embodiment 2

[0029] like Figure 1 and Figure 3 As shown, the radiator proposed by the utility model, compared with the first embodiment, is provided with a plurality of heat dissipation plates 74 on the outer surface of the radiator body 7, the outer end surface of the heat dissipation fin 9 is in contact with the inner wall of the storage cavity 71 of the radiator body 7, and the heat dissipation fin 9 is located in the cooling medium.

[0030] In this embodiment, a portion of the heat on the heat dissipation fins 9 is transferred to the radiator body 7, and heat is exchanged with the external natural air through the heat dissipation plate 74, thereby further improving the cooling efficiency of the heat dissipation fins 9. At the same time, in the early stage of the lamp bead lighting, the temperature and heat dissipation can be directly cooled and dissipated through this structure without starting the refrigerator 8, thereby achieving the purpose of energy saving and intelligent allocation of cooling and heat dissipation methods.

[0031] Embodiment 3

[0032] like Figure 1-Figure 4 As shown, the utility model also proposes an LED lamp with the heat sink described in the first and second embodiments, which also includes a lamp housing 1 with a lamp bead 2, a heat conducting rod 6 and a card assembly, and the card assembly includes a movable plate 3 and a card block 5; a plurality of sockets are arranged on the peripheral side of the movable plate 3, each card block 5 is respectively located in the corresponding side socket and elastically slidably connected to the movable plate 3, a cavity is arranged in the lamp housing 1, and the movable plate 3 is located in the cavity and slidably connected to its inner wall; a plurality of slide grooves 101 connected to the cavity are arranged in a circular array on the peripheral side of the lamp housing 1, each card block 5 respectively penetrates the corresponding side slide groove 101 and is slidably connected thereto, the heat conducting rod 6 penetrates the lamp housing 1 and is connected to the heat conducting column 8, and a plurality of through holes 301 are arranged on the movable plate 3, the heat conducting rod 6 is located on the inner side of the through hole 301 and is slidably connected thereto, a terminal A14 is arranged on the lamp housing 1, and a terminal B15 detachably connected to the terminal A14 is arranged on the radiator body 7, and the terminal A14 is electrically connected to the terminal B15;

[0034] In the present embodiment, when the LED lamp with a heat sink is actually installed, the heat sink body 1 is inserted into the pre-opened hole until the lamp housing 1 is fitted with the mounting plate. During the process, the block 5 automatically retracts when it contacts the edge of the hole, and then automatically pops out after fully entering the hole. The staff only needs to rotate the screw rod 4 to drive the movable plate 3 to slide toward the side of the lamp housing 1 with the lamp bead 2. When the block 5 is pressed against the side of the mounting plate away from the lamp bead 2, the installation can be complete. When disassembling, it is only necessary to continuously rotate the screw rod 4 in the opposite direction so that the movable plate 3 is located above the slide groove 101. At this time, the block 5 automatically retracts under the obstruction of the inner wall of the slide groove 101, and the entire device can be directly removed.

[0035] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
