Description

Technical Field

[0001] The utility model relates to the field of branch boxes, in particular to a branch box which is convenient for heat dissipation. Background Art

[0002] The cable branch box is used as a cable branch, mainly for cable tapping and cable transfer. When the independent load with small capacity is distributed more concentratedly, the cable branch box can be used to connect multiple branches of the cable. Since there are more electrical components concentrated inside the cable branch box, during its operation, the current passes through the inside of the branch box, which will generate a lot of heat, which will cause rapid aging of the cable.

[0003] In order to ensure normal heat dissipation of the branch box, manufacturers usually install cooling fans inside the branch box to dissipate heat inside the branch box by accelerating the airflow between the inside and outside of the branch box. However, since electrical components are usually installed at the bottom of the inner wall of the branch box, the airflow at the bottom is difficult to flow, resulting in poor heat dissipation effect. Utility Model Content

[0004] The main purpose of the utility model is to provide a branch box that is easy to dissipate heat, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a branch box that is easy to dissipate heat, including a branch box body, the top and bottom of the branch box body are provided with expansion boxes, the expansion box is connected to the interior of the branch box body, a partition plate is provided between the expansion box and the branch box body, the surface of the partition plate is provided with a plurality of laterally distributed long grooves, electrical components are installed between the two partition plates, and a cooling fan and a refrigeration component are installed inside the expansion box.

[0006] The internal shape of the capacity expansion box is a triangular column, and the two capacity expansion boxes are installed in a symmetrical shape. The cooling fan and the refrigeration components are both installed inside the capacity expansion box at the top position.

[0007] A first sealing door is installed on the surface of the upper expansion box, and a second sealing door is installed on the surface of the branch box body. The second sealing door shields the branch box body and the expansion box below.

[0008] The refrigeration component includes two refrigeration fins, which are installed on the top of the inner wall of the expansion box. The heat-absorbing surface of the refrigeration fin faces the interior of the branch box body, and the heat-dissipating surface of the refrigeration fin is away from the interior of the branch box body. A plurality of through grooves are opened on the surface of the expansion box, and a plurality of heat-dissipating fins are installed on the heat-dissipating surface of the refrigeration fin, and the heat-dissipating fins extend to the outside of the through grooves.

[0010] There are two support plates, which are respectively against two sides of the cooling fan.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. In the utility model, by setting the expansion box, refrigeration parts and cooling fans, cooling can be carried out when the refrigeration parts are started. Due to the air density, the cold air flow will decrease and the hot air flow will increase. When the cooling fan is started, it can drive the gas flow, realize heat transfer, and thus take away the heat generated by the electrical components. In addition, the gas can flow between the two expansion boxes to ensure better heat dissipation effect.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, a branch box that is easy to dissipate heat includes a branch box body 1, and expansion boxes 2 are provided on the top and bottom of the branch box body 1. The expansion box 2 and the branch box body 1 are made of the same material and can be an integrated structure. The expansion box 2 is connected to the inside of the branch box body 1, and a partition plate 3 is provided between the expansion box 2 and the branch box body 1. The surface of the partition plate 3 is provided with a plurality of transversely distributed long grooves, and electrical components are installed between the two partition plates 3. A cooling fan 4 and a refrigeration component are installed inside the expansion box 2.

[0021] Since the electrical components are installed between the two partition plates 3, there is a certain amount of space on the top and bottom. The refrigeration component can be started to cool down and change the air temperature inside the expansion box 2. When the cooling fan 4 is started, it can drive the gas flow, realize heat transfer, and take away the heat generated by the electrical components. The gas can flow between the two expansion boxes 2 to ensure better heat dissipation effect.

[0022] The internal shape of the capacity expansion box 2 is a triangular column, and the two capacity expansion boxes 2 are installed in a symmetrical shape. The heat dissipation fan 4 and the refrigeration components are installed inside the capacity expansion box 2 at the top position.

[0023] Due to the air density, the cold air flow will descend and the hot air flow will rise. Therefore, installing the refrigeration component in the upper position can speed up the flow of the cold air flow, and there are no windows connected to the outside inside the branch box body 1 and the expansion box 2, which can reduce the inflow of external air, thereby reducing the entry of dust and ensuring sufficient heat dissipation effect.

[0024] A first sealing door 5 is installed on the surface of the expansion box 2 above. The first sealing door 5 is triangular in shape and matches the shape of the expansion box 2. A second sealing door 6 is installed on the surface of the branch box body 1. The shape of the second sealing door 6 is pentagonal. The second sealing door 6 blocks the branch box body 1 and the expansion box 2 below, dividing them into two areas. The area below can be used for maintenance of electrical components and dust disposal. The space above is mainly responsible for heat dissipation to delay the aging of electrical components.

[0025] The refrigeration component includes two refrigeration fins 7, which are installed on the top of the inner wall of the expansion box 2 and on both sides respectively. The heat-absorbing surface of the refrigeration fins 7 faces the interior of the branch box body 1 to take away the heat generated by the electrical components. The heat dissipation surface of the refrigeration fins 7 is away from the interior of the branch box body 1 and dissipates the heat through the heat dissipation surface. A plurality of through grooves 8 are provided on the surface of the expansion box 2. A plurality of heat dissipation fins 9 are installed on the heat dissipation surface of the refrigeration fins 7. The heat dissipation fins 9 extend to the outside of the through grooves 8. Since the heat dissipation fins 9 are in direct contact with the external air, the heat can be taken away more quickly.

[0026] A support plate 10 is installed inside the expansion box 2, and the bottom of the support plate 10 is set to be stepped. The bottom of the support plate 10 is stuck in the long groove of the partition plate 3, and the top of the support plate 10 is against the surface of the refrigeration plate 7. The support plate 10 has a certain supporting force on the refrigeration plate 7, thereby ensuring the stable installation of the refrigeration plate 7.

[0027] There are two support plates 10 , which are respectively against two sides of the cooling fan 4 to limit the position of the cooling fan 4 and ensure the stability of the cooling fan 4 .

[0028] It should be noted that the utility model is a branch box that is easy to dissipate heat. When in use, the electrical components are installed between the two partition plates 3, the refrigeration plate 7 is started, and the heat absorption surface faces the inside of the branch box body 1, so as to take away the heat generated by the electrical components and change the air temperature inside the expansion box 2. The cold air flow will decrease and the hot air flow will rise. Therefore, installing the refrigeration component in the upper position can speed up the flow of the cold air flow. When the cooling fan 4 is started, it can drive the gas flow, realize heat transfer, and thus take away the heat generated by the electrical components, and the gas can flow between the two expansion boxes 2 to ensure better heat dissipation effect. There are no windows connected to the outside in the branch box body 1 and the expansion box 2, which can reduce the inflow of external air, thereby reducing the entry of dust and ensuring sufficient heat dissipation effect. The heat dissipation surface is away from the inside of the branch box body 1 and dissipates through the heat dissipation surface. Since the heat dissipation fins 9 are in direct contact with the external air, the heat can be taken away more quickly.
