DETAILED DESCRIPTION
[0016] The utility model is further described below in conjunction with the accompanying drawings.
[0017] Reference Figure 1As shown, a cable branch box with good heat dissipation effect comprises a branch box body 1, a water storage tank 2 is arranged at the bottom end of the branch box body 1, a water supply and distribution pipe 3 is arranged on one side of the branch box body 1, and a water outlet and return pipe 4 is arranged on the other side of the branch box body 1. Inside the branch box body 1, a plurality of cooling water pipes 5 are arranged layer by layer from top to bottom, one end of the plurality of cooling water pipes 5 passes through the branch box body 1 and is connected to the water supply and distribution pipe 3, the other end of the plurality of cooling water pipes 5 passes through the branch box body 1 and is connected to the water outlet and return pipe 4, the bottom end of the water outlet and return pipe 4 is connected to the water storage tank 2, and the water supply and distribution pipe 3 is far away from the branch box A water pump 6 is arranged on one side of the main body 1, and one end of the water pump 6 is connected with the water tank 2 through a pipeline. The water pump 6 sends the cooling medium in the water tank 2 into the water supply pipe 3 through the pipeline, and then sends it into multiple cooling water pipes 5 through the water supply pipe 3. The cooling water pipe 5 is located inside the branch box main body 1. Then the cooling medium takes away the heat from the inside of the branch box main body 1, flows to the inside of the water outlet and return pipe 4 outside the branch box main body 1, and finally flows into the water tank 2. When the water outlet and return pipe 4 arranged on the outside returns water to the water tank 2, the cooling medium in the water outlet and return pipe 4 can exchange heat with the outside and cool down.
[0018] A plurality of first heat sinks 7 are arranged at intervals at the top of the branch box body 1, and the bottom ends of the first heat sinks 7 extend to the inside of the branch box body 1. When the internal air is heated, its volume expands, and the air density decreases and rises. The bottom ends of the first heat sinks 7 extend to the inside of the branch box body 1, which effectively increases the heat absorption area of the top of the inside of the branch box body 1 under the same projected area, so that the internal high-temperature air can quickly exchange heat with the outside world through the first heat sink 7 and the top of the inside of the branch box body 1, and cooperate with the cooling water pipe 5 to make the heat dissipation effect inside the branch box body 1 better and the heat dissipation efficiency higher, so that there is no need to set a heat dissipation port on the branch box body 1, and efficient heat dissipation can be carried out. The inside of the branch box body 1 is not connected to the outside world for a long time, and the external environment can be effectively prevented from affecting the working stability of the components inside the cable branch box.
[0019] Preferably, a plurality of second heat sinks 8 are evenly arranged on both sides of the water tank 2 from top to bottom, and one end of the second heat sink 8 extends into the interior of the water tank 2. The second heat sink 8 increases the heat dissipation area of the water tank 2 under the same projected area, so that the cooling medium after the water returns to the water tank 2 is cooled, making the cooling cycle more stable.
[0020] Preferably, a dehumidifier 9 is provided at the top of one side of the branch box main body 1. The dehumidifier 9 is prior art and will not be described in detail here. The dehumidifier 9 can keep the internal air dry and prevent water vapor from affecting the internal components.
[0021] Preferably, a temperature and humidity sensor 10 is provided inside the branch box body 1, and a controller 11 is provided at the bottom end inside the branch box body 1. The controller 11 controls the operation of the dehumidifier 9 according to the signal of the temperature and humidity sensor 10. The controller 11 is connected with the temperature and humidity sensor 10, the temperature sensor 14, the cooling fan 13, and the water pump 6. The temperature and humidity sensor 10 monitors the temperature and humidity inside the branch box body 1 in real time. When the controller 11 detects that the internal temperature is higher than the safety value, the water pump 6 is driven to work and cooling water is input to the cooling water pipe 5 for cooling. When it is detected that the internal temperature is below the safety value, the water pump 6 is stopped. When the controller detects that the internal humidity is higher than the safety value, the dehumidifier 9 is controlled to work. When the internal humidity is detected to be at the safety value, the dehumidifier 9 is stopped, making it more energy-saving.
[0022] Preferably, a mounting plate 12 is provided on the side of the water outlet return pipe 4 away from the branch box body 1, and a plurality of cooling fans 13 are provided on the mounting plate 12 from top to bottom. A temperature sensor 14 for detecting the inside of the water tank 2 is provided on the water tank 2. The temperature sensor 14 detects the temperature inside the water tank 2. When the internal temperature of the water tank 2 rises above the safe value due to the high return water temperature, the controller 11 controls the cooling fan 13 to work, and blows the external airflow at high speed toward the water outlet return pipe 4 and the branch box body 1 to cool the cooling medium of the return water and the branch box.
[0023] Preferably, a water inlet pipe 15 is provided on one side of the top of the water tank 2, and an electromagnetic control valve 16 is provided on the end of the water inlet pipe 15 away from the water tank 2. The electromagnetic control valve 16 is also connected to the controller 11. The water level in the water tank 2 is at three quarters of the water tank 2. The water inlet pipe 15 is connected to an external water supply tank through the electronic control valve 16. When the temperature of the cooling medium of the return water of the water tank 2 is high, resulting in a high internal temperature, the controller 11 controls the electromagnetic control valve 16 to open, so that the external low-temperature cooling water is sent into the water tank 2 for neutralization and cooling.
