[0004] Although the above patent has a relatively good heat dissipation effect through two methods of air cooling and water cooling, when the water is in contact with the temperature for a long time, the temperature of the water will change, resulting in unstable heat dissipation effect in the later stage. Secondly, in the water cooling design, a cold water storage box, a cold water suction pump, and a cold water circulation pipe need to be added, which will cause the overall volume of the capacitor cabinet to increase.

Specific implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1-3 , the present utility model provides a technical solution: a vertical capacitor cabinet conducive to heat dissipation, including a cabinet body 1. The inner cavity of the cabinet body 1 is symmetrically provided with 5. The back of the cabinet body 1 is provided with a heat dissipation port 3. The heat dissipation port 3 is used for the automatic heat dissipation effect with a relatively low temperature. The surface of the cabinet body 1 is rotatably connected with a cabinet door 4. Among them, the cabinet door 4 is divided into upper and lower parts. The top of the cabinet body 1 is symmetrically provided with mounting grooves for the rotation of the pulley two 233. Through the mounting grooves, the connection and rotation of the belt 22 are not affected. Then, the rotating plate 231 is installed in the middle of the top of the cabinet body 1. The rotating rod passes through the mounting groove and is inserted into the rotating plate 231. Then, the pulley two 233 sleeved with the belt 22 is installed on the rotating rod. In addition, the sealing strip 232 will be in mutual extrusion contact with the inner wall of the top of the cabinet body 1.

[0027] Please refer to Figure 4, a heat dissipation structure 2 is provided between the two sides and the top of the cabinet body 1. The heat dissipation structure 2 is composed of a belt 22, a heat dissipation component 23 and two cooling components 21. The belt 22 is used to connect the cooling component 21 and the heat dissipation component 23.

[0028] Please refer to Figure 5 , both of the two cooling components 21 include a mounting plate 211. The mounting plate 211 is fixedly connected to the side surface of the cabinet body 1. A semiconductor refrigerator 212 and a conduction plate 213 are respectively arranged on the surface of the mounting plate 211. The semiconductor refrigerator 212 and the conduction plate 213 extend into the inner cavity of the cabinet body 1. An installation opening for the semiconductor refrigerator 212 and the conduction plate 213 to enter is provided on the side surface of the cabinet body 1. Therefore, the semiconductor refrigerator 212 and the conduction plate 213 can directly enter the inner cavity of the cabinet body 1 along the installation opening. In addition, the belt 22 is close to the inner cavity of the cabinet body 1 in the inner cavity of the cabinet body 1, but does not directly contact the inner wall, and there will be a gap between the two.

[0029] The conduction plate 213 is made of aluminum, and the conduction plate 213 is attached to the surface of the semiconductor refrigerator 212. A circuit board 215 and a fan 214 are respectively arranged on the surface of the conduction plate 213. A protective plate 216 is fixedly connected to the surface of the conduction plate 213, and the protective plate 216 is located on the surface of the circuit board 215. The protective plate 216 is used to protect the circuit board 215. A protective net 218 is fixedly installed on the surface of the fan 214. The protective net 218 is used for dust prevention. The output end of the fan 214 is fixedly sleeved with a pulley one 217 through a rotating rod.

[0030] The semiconductor refrigerator 212 is a device that uses the thermoelectric effect of semiconductors to produce cooling capacity. Two different metals are connected by a conductor. When direct current is connected, the temperature at one contact point decreases, and the temperature at the other contact point increases. Since the conduction plate 213 is in close contact with the semiconductor refrigerator 212, the cooling generated by the semiconductor refrigerator 212 will be conducted to the conduction plate 213.

[0031] Among them, the semiconductor refrigerator 212 and the fan 214 are electrically connected to the circuit board 215. The specific process is that when 5 detects that the temperature in the inner cavity of the cabinet body 1 exceeds the set value, it will transmit a signal to the circuit board 215, and the circuit board 215 controls the semiconductor refrigerator 212 and the fan 214 to start. When the semiconductor refrigerator 212 starts, it will refrigerate, and then the fan 214 rotates to quickly transport the cold air conducted by the conduction plate 213.

[0032] Please refer to Figure 6, the heat dissipation component 23 includes a rotating plate 231. The rotating plate 231 is rotatably sleeved in the middle of the top of the cabinet body 1 and is flush with the top of the cabinet body 1. Both ends of the rotating plate 231 are fixedly sleeved with a second pulley 233 through a rotating rod, and sealing strips 232 are arranged on both sides of the rotating plate 231. A counterweight strip 234 is fixedly connected to the bottom of the rotating plate 231, and the belt 22 is movably sleeved on the first pulley 217 and the second pulley 233.

[0033] During use, first, the temperature inside the cabinet body 1 is detected. When the temperature exceeds the set value, the semiconductor refrigerator 212 and the fan 214 are started through the circuit board 215. The semiconductor refrigerator 212 will refrigerate and conduct on the conduction plate 213, and thus the conduction plate 213 will generate cold air. After the fan 214 rotates, the cold air generated on the surface of the conduction plate 213 will be quickly transported into the inner cavity of the cabinet body 1. At the same time, through the belt 22 on the first pulley 217 and the second pulley 233, it rotates and drives the rotating plate 231 to also rotate on the top of the cabinet body 1, so that the rotating plate 231 also forms a fan. The cold air will discharge the hot air to the upper part of the inner cavity of the cabinet body 1, and the rotating rotating plate 231 will generate a blowing force, so as to blow outward from the inside, quickly discharging the hot air above, so as to achieve the effect that the electrical components in the cabinet body 1 can be quickly cooled. The cold air generated by refrigeration will not change due to the temperature of water cooling, so the heat dissipation effect can always be maintained. In addition, after the cooling component 21, the belt 22 and the heat dissipation component 23 are combined, the overall volume is compact and small, and it will not increase the volume when installed on the capacitor cabinet.

[0034] When it is detected that the temperature drops to the set value, the semiconductor refrigerator 212 and the fan 214 will be stopped through the circuit board 215. After the fan 214 stops, the first pulley 217, the second pulley 233 and the belt 22 will also stop accordingly. When the rotating plate 231 loses the power to rotate, through the counterweight strips 234 arranged on the left and right at the bottom of the rotating plate 231, under the action of its own weight, it will drive the rotating plate 231 to automatically reset and cover the top of the cabinet body 1. At the same time, the sealing strips 232 on both sides can play a sealing role.

[0035] It should be noted that the left and right counterweight strips 234 are of the same weight. Therefore, in order to achieve balance, after driving the rotating plate 231 to reset, the rotating plate 231 is flush with the top of the cabinet body 1. In addition, when the rotating plate 231 automatically resets, its second pulley 233, the first pulley 217 and the belt 22 will drive the stopped fan 214 to rotate back and forth at one end. Since the stopped fan 214 has no power to rotate, the rotation does not affect the next rotation of the fan 214.

[0036] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
