[0023] As shown Figures 1-6 in the figure, a self-cooling electric energy metering box includes a metering box body 1. One side of the metering box body 1 is connected with a cabinet door 2. A hinge 201 is connected to the cabinet door 2. The cabinet door 2 is hinged to the metering box body 1 through the hinge 201. A transparent plate 203 is fixedly connected to the cabinet door 2. A handle 202 is fixedly connected to one side of the cabinet door 2. A plurality of support blocks 101 are fixedly connected to the lower end of the metering box body 1. It further includes a heat dissipation mechanism 3. The heat dissipation mechanism 3 is connected to the metering box body 1. The heat dissipation mechanism 3 includes a heat conducting plate 301, a control pump 307 and a radiator 310. A liquid storage tank 103 is arranged in the metering box body 1. One side of the liquid storage tank 103 is open. The heat conducting plate 301 is hermetically connected to the liquid storage tank 103. Liquid outlet channels 105 and liquid return channels 106 are arranged on both sides of the metering box body 1. One end of the control pump 307 communicates with the liquid outlet channel 105 and the liquid return channel 106. The other end of the control pump 307 communicates with the radiator 310. The radiator 310 is fixedly connected to both sides of the control pump 307.
[0024] As shown Figure 2 and 4 in the figure, in order to hermetically connect the heat conducting plate 301 to the liquid storage tank 103, a support frame 104 is fixedly connected in the liquid storage tank 103. Bolts 302 are inserted through the heat conducting plate 301. The bolts 302 are threadedly connected to the support frame 104. A sealing ring 303 is arranged between the heat conducting plate 301 and the support frame 104. The heat conducting plate 301 and the support frame 104 press and fix the sealing ring 303.
[0025] As shown Figure 4 in the figure, in order to install various metering devices in the metering box body 1, an installation frame 304 is arranged on the right side of the heat conducting plate 301. A connecting strip 305 is fixedly connected to one side of the installation frame 304. The connecting strip 305 is fixedly connected to the heat conducting plate 301. A plurality of hollow parts 306 are arranged on the installation frame 304, so that the heat of the device is conducted to the heat conducting plate 301.
[0026] As shown Figure 3 and 5As shown in FIGS. 6, two sides of the metering box body 1 are fixedly connected with limiting frames 107. The control pump 307 and the radiators 310 fixedly connected to both sides thereof are fixedly connected within the limiting frames 107. One side of the control pump 307 is fixedly connected with a liquid inlet pipe 308 and a liquid outlet pipe 309. The liquid inlet pipe 308 is hermetically connected to the liquid outlet channel 105, and the liquid outlet pipe 309 is hermetically connected to the liquid return channel 106. A connection groove 311 is provided on the radiator 310, and a cooling fan 312 is connected within the connection groove 311. Thus, the coolant that has absorbed the heat of the heat conducting plate 301 circulates in the radiator 310 under the control of the control pump 307, and then is cooled by the cooling fan 312 and returns to the liquid storage tank 103 to achieve heat dissipation.
[0027] As Figures 1-3 shown, a plurality of heat dissipation holes 102 are provided on both sides of the metering box body 1, so that the air inside and outside the metering box body 1 can flow, further promoting the heat dissipation inside the metering box body 1. The heat dissipation holes 102 are inclined. The heat dissipation holes 102 are inclined downward from the inside to the outside of the metering box body 1. Thus, when the external air enters the metering box body 1, it first impacts the bottom surface of the heat dissipation holes 102 for blocking, thereby achieving a certain dust-proof effect.
[0028] As Figure 2 shown, a temperature sensor 4 is fixedly connected inside the metering box body 1, so that the temperature inside the metering box body 1 can be monitored in real time to avoid overheating inside the metering box body 1.
[0029] When the present utility model is in use, the electric energy meter, the metering voltage, the current transformer, etc. are connected to the mounting frame 304 by screws, etc. The metering equipment generates heat during operation, and the heat is transferred to the heat conducting plate 301. The coolant filled in the liquid storage tank 103 absorbs the heat on the heat conducting plate 301 and the temperature rises. The control pump 307 extracts the heated coolant in the liquid storage tank 103 through the liquid inlet pipe 308 from the liquid outlet channel 105, and imports the extracted coolant into the radiator 310. The coolant flows in the radiator 310 and the heat is dissipated by the cooling fan 312, thereby achieving the cooling of the coolant. Then, the cooled coolant is returned to the liquid storage tank 103 through the liquid outlet pipe 309 by the control pump 307 from the liquid return channel 106 to achieve heat dissipation. The heat dissipation holes 102 on both sides of the metering box body 1 can make the air inside and outside the metering box body 1 flow, thereby dissipating heat inside the metering box body 1. And by monitoring the temperature inside the metering box body 1 through the temperature sensor 4, manual handling can be carried out in time when the temperature inside the metering box body 1 is too high.
[0030] In summary: In the embodiment of the present utility model, each metering device is installed in the metering box body 1 through the mounting frame 304. The coolant is stored in the liquid storage tank 103. The heat of the device is conducted to the coolant by the heat conduction plate 301. The control pump 307 is used to circulate the coolant in the radiator 310 and the heat dissipation fan 312 is used for heat dissipation, and then the coolant flows back to the liquid storage tank 103, thereby realizing the heat dissipation in the metering box body 1, with good heat dissipation effect and high efficiency.
