[0024] EMBODIMENT

[0025] REFERENCE Figures 1-4 For the embodiment of the utility model, the embodiment provides a heat dissipation structure for a large communication power supply module, which comprises,

[0026] The power supply body 100 comprises a power supply shell 101, a power supply interface 102 fixedly connected to the outer surface of the power supply shell 101, and a heat dissipation port 103 opened at the top of the power supply shell 101;

[0027] It should be noted that the power supply shell 101 is the shell of the entire power supply body 100, which is used for protecting the internal components, the power supply interface 102 is used for connecting external power supply or equipment, and the heat dissipation port 103 is used for helping air circulation to improve the heat dissipation efficiency.

[0028] The cooling mechanism 200 comprises a protection assembly 201 arranged outside the heat dissipation opening 103 for preventing dust from entering, and a driving assembly 202 arranged inside the power supply shell 101 for controlling the protection assembly 201 to open when the temperature inside the power supply shell 101 rises.

[0029] Specifically, the protection assembly 201 comprises a fixed disc 201a fixedly arranged on the top of the power supply shell 101, a through slot 201b arranged outside the fixed disc 201a, a swing frame 201c movably connected to the inner surface of the through slot 201b, and a rotating disc 201d fixedly connected to the outer end surface of the swing frame 201c.

[0030] It should be noted that the through slot 201b is used to accommodate the swing frame 2010c, and when the swing frame 201c swings, the rotating disc 201d can be driven to rotate.

[0031] Further, the protection assembly 201 further comprises a plurality of hinged rods 201e hingedly connected to the outer surface of the rotating disc 201d, a hinged plate 201f hingedly connected to the other end of the hinged rod 201e, a rotating column 201g fixedly connected to the top of the power supply shell 101 and cooperating with the hinged plate 201f, a plurality of limiting columns 201h fixedly connected to the top of the power supply shell 101, and a plurality of limiting grooves 201i arranged on the surface of the hinged plate 201f and cooperating with the limiting columns 201h.

[0032] It should be further noted that the hinged plate 201f can form a closed circle when it is closed, so as to cover the heat dissipation opening 103, and when the rotating disc 201d rotates, the hinged plate 201f is driven to rotate around the rotating column 201g through cooperation with the hinged rod 201e.

[0033] Preferably, the rotating disc 201d is located inside the fixed disc 201a, the plurality of hinged rods 201e are arranged in a circumferential array on the top of the rotating disc 201d, the outer surface of the rotating column 201g is rotatably connected to the inner surface of the hinged plate 201f, and the inner wall of the limiting column 201h is in sliding contact with the outer surface of the limiting groove 201i.

[0034] It should be noted that the driving assembly 202 comprises a heat-conducting sleeve 202a fixedly arranged on the top of the power supply shell 101, a thermal expansion block 202b arranged in the inner cavity of the heat-conducting sleeve 202a, a sliding block 202c slidably connected to the inner surface of the heat-conducting sleeve 202a, and a connecting rod 202d fixedly connected to the side of the sliding block 202c away from the thermal expansion block 202b.

[0035] The heat-conducting sleeve 202a is used to transmit the temperature of the electrical elements inside the power supply shell 101 to the thermal expansion block 202b, so that the thermal expansion block 202b expands and elastically deforms, and then pushes the sliding block 202c to move.

[0036] Further, the driving assembly 202 further comprises a driving block 202e fixedly installed at the penetrating end of the connecting rod 202d and used in cooperation with the swing frame 201c, and a spring 202f sleeved on the outer surface of the connecting rod 202d and used in cooperation with the sliding block 202c.

[0037] It needs to be explained that when the sliding block 202c moves, the driving block 202e can be driven to move synchronously, so that the driving block 202e slides on the inner surface of the swing frame 201c and drives the swing frame 201c to swing.

[0038] Specifically, the outer surface of the connecting rod 202d is in sliding contact with the inner surface of the heat conduction sleeve 202a, and the outer surface of the driving block 202e is in sliding contact with the inner surface of the swing frame 201c.

[0039] In use, in the normal state: the thermal expansion block 202b is in a contracted state, the sliding block 202c, the connecting rod 202d and the driving block 202e are located at the initial position, the opening and closing plate 201f is kept closed through the limiting column 201h and the limiting groove 201i, and the heat dissipation port 103 is sealed to prevent dust from entering.

[0040] When the internal temperature of the power shell 101 rises: the heat conduction sleeve 202a transmits heat to the thermal expansion block 202b, so that the thermal expansion block 202b is heated and expanded, the sliding block 202c is pushed to move by the thermal expansion block 202b, the connecting rod 202d drives the driving block 202e to move, and the swing frame 201c is swung by the driving block 202e, so that the rotating disc 201d is rotated by the swing frame 201c, the opening and closing plate 201f is rotated around the rotating column 201g by the hinged rod 201e, and the heat dissipation port 103 is exposed to the outside, so that the air circulation is enhanced and heat dissipation is facilitated.

[0041] After the internal temperature of the power shell 101 decreases: the thermal expansion block 202b contracts, the sliding block 202c, the connecting rod 202d and the driving block 202e are returned to the initial position by the reaction force of the spring 202f, the driving block 202e drives the swing frame 201c and the opening and closing plate 201f to synchronously recover to the closed state, the heat dissipation port 103 is resealed, and dust is prevented from entering.

[0042] In summary, through the cooperation of the various components in the protection assembly 201 and the driving assembly 202, when the internal temperature of the power shell 101 rises, the opening and closing plate 201f is opened to enhance air circulation and facilitate heat dissipation; when the internal temperature of the power shell 101 decreases, the opening and closing plate 201f is closed to prevent dust from entering, without manual intervention, and the power module is ensured to operate at an appropriate temperature, so as to prolong the service life of the power module and reduce the risk of failure caused by overheating.
