Description
Technical Field
[0001] The utility model belongs to the technical field of electric wires, and in particular relates to an electric wire for energy storage which is resistant to high temperature and has high efficiency in heat dissipation. Background Art
[0002] The power plant energy storage system is a system for storing electrical energy, which is mainly used to balance the grid load and improve the stability and reliability of the power system. Due to the high operating frequency of the energy storage system, a large number of lines are required to connect the battery and the energy storage circuit. Long-term high-load work has high requirements on the high temperature resistance and heat dissipation capacity of the wires of the energy storage system. At present, in order to solve the heat dissipation problem, water-cooled circuits have appeared, that is, a water-cooled interlayer is set on the outside of the wire to play a role in heat dissipation. However, this type of circuit has the following disadvantages. First, the interlayer is usually long and is a whole, that is, the water bag layer completely wraps the outside of the wire, so it has a greater impact on the bending ability of the wire. At the same time, when leakage or damage occurs, it is inconvenient to replace and the cost is high. Utility Model Content
[0003] In view of the above problems, the purpose of the utility model is to provide a high-temperature resistant and efficient heat dissipation energy storage wire, which has a limited effect on the bending of the wire body and greatly improves reliability. When a set of heat dissipation sheaths is damaged, it is only necessary to remove this set of heat dissipation sheaths for replacement, which undoubtedly reduces the overall maintenance difficulty and cost.
[0004] To achieve the above objectives, the utility model provides the following technical solutions: a high-temperature resistant and efficient heat dissipation energy storage wire, comprising a wire body, the wire body comprising a wire sheath, a wire core is arranged inside the wire sheath, a filler is filled between the wire sheath and the wire core, a heat dissipation sheath is arranged on the outside of the wire sheath, five groups of strip water cooling bags are arranged inside the heat dissipation sheath, a front connecting plate is arranged at the front end of the heat dissipation sheath, a rear connecting plate is arranged at the rear end of the heat dissipation sheath, a first side connecting plate and a second side connecting plate are arranged on the side of the heat dissipation sheath, evenly arranged arc-shaped heat conducting plates are embedded on the inner side of the heat dissipation sheath, an integrally formed heat conducting nail is arranged on one side of the arc-shaped heat conducting plate, the heat conducting nail passes through the outside of the heat dissipation sheath, connecting holes are penetrated between the front and rear side surfaces of the front connecting plate and the rear connecting plate, and between the upper and lower side surfaces of the first side connecting plate and the second side connecting plate, and the connecting holes are connected to plastic snaps.
[0005] The beneficial effects of the utility model are as follows: when the electric wire body transmits electric current through the wire core, the generated heat is conducted to the strip water cooling bag through the wire sheath, and the heat is effectively absorbed by the cooling water in the strip water cooling bag. Since the ventilation holes are provided, the airflow can enter the interior of the heat dissipation jacket and flow in the ventilation grooves. The heat exchange is carried out between the air and the heat in the cooling water in the strip water cooling bag and the heat conducted to the heat dissipation jacket, and part of the heat can be taken away. At the same time, since the evenly arranged arc-shaped heat conducting sheets and heat conducting nails are provided, the heat in the strip water cooling bag can be conducted to the arc-shaped heat conducting sheets, and the heat conducting nails contacted by the outside air can absorb the heat. Heat dissipation is carried out, and since the arc-shaped heat-conducting plates and heat-conducting nails are evenly arranged and spaced, they do not affect the bending of the wire body. At the same time, since there are five independent strip water-cooling bags and each set of heat-dissipating sleeves is relatively short, the bending effect on the wire body is also limited. At the same time, the bending and tensile resistance of the strip water-cooling bags themselves are improved, and the reliability of the water-cooled pipeline is improved. The method of combining and sleeved multiple sets of heat-dissipating sleeves on the outside of the wire sheath also greatly improves the reliability. When one set of heat-dissipating sleeves is damaged, only this set of heat-dissipating sleeves needs to be removed and replaced, which undoubtedly reduces the overall maintenance difficulty and cost.
[0006] To assemble multiple sets of thermal jackets:
[0007] As a further improvement of the above technical solution: two adjacent groups of heat dissipation jackets are fixed to each other by fixing the connection holes on the front connection plate and the connection holes on the rear connection plate by means of the plastic snaps.
[0008] The beneficial effect of the present improvement is that two adjacent groups of heat dissipation jackets are fixed to each other by fixing the adjacent connection holes on the front connection plate and the connection holes on the rear connection plate with plastic snaps, thereby assembling multiple groups of heat dissipation jackets.
[0009] To secure the heatsink to the outside of the wire sheathing:
[0010] As a further improvement of the above technical solution: the first side connecting plate and the second side connecting plate are fixed by fixing the connecting hole of the first side connecting plate and the connecting hole of the second side connecting plate through the plastic snaps.
[0011] The beneficial effect of this improvement is that the first side connecting plate and the second side connecting plate are fixed by fixing the connecting hole of the first side connecting plate and the connecting hole of the second side connecting plate through the plastic snaps, thereby fixing the heat dissipation sheath to the outside of the wire sheath.
[0012] For partial heat dissipation:
[0013] As a further improvement of the above technical solution: ventilation holes are provided through the front connecting plate and the rear connecting plate, and ventilation grooves are provided between two adjacent groups of strip-shaped water cooling bags.
[0014] The beneficial effect of this improvement is that due to the provision of ventilation holes, air flow can enter the interior of the heat dissipation jacket and flow in the ventilation grooves, and heat can be taken away by heat exchange between the air and the heat in the cooling water in the strip water cooling bag and the heat conducted into the heat dissipation jacket.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.
[0024] like Figure 1-6As shown, a high-temperature resistant and efficient heat dissipation energy storage wire comprises a wire body, the wire body comprises a wire sheath 1, a wire core 2 is arranged inside the wire sheath 1, a filler 3 is filled between the wire sheath 1 and the wire core 2, a heat dissipation sheath 4 is arranged on the outside of the wire sheath 1, five groups of strip-shaped water-cooling bags 5 are arranged inside the heat dissipation sheath 4, a front connecting plate 6 is arranged at the front end of the heat dissipation sheath 4, a rear connecting plate 7 is arranged at the rear end of the heat dissipation sheath 4, a first side connecting plate 8 and a second side connecting plate 9 are arranged on the side of the heat dissipation sheath 4, evenly arranged arc-shaped heat conducting plates 10 are embedded on the inner side of the heat dissipation sheath 4, one side of the arc-shaped heat conducting plate 10 is provided with an integrally formed heat conducting nail 11, the heat conducting nail 11 penetrates the outside of the heat dissipation sheath 4, connecting holes 12 are penetrated between the front and rear sides of the front connecting plate 6 and the rear connecting plate 7, and between the upper and lower sides of the first side connecting plate 8 and the second side connecting plate 9, and the connecting holes 12 are connected to plastic snaps 13.
[0025] When the wire body transmits current through the wire core 2, the generated heat is conducted to the strip water cooling bag 5 through the wire sheath 1, and the heat is effectively absorbed by the cooling water in the strip water cooling bag 5. Due to the provision of the ventilation holes 14, the airflow can enter the interior of the heat dissipation jacket 4 and flow in the ventilation slots 15. The heat exchange between the air and the heat in the cooling water in the strip water cooling bag 5 and the heat conducted to the heat dissipation jacket 4 can take away part of the heat. At the same time, due to the provision of the evenly arranged arc-shaped heat conducting sheets 10 and heat conducting nails 11, the heat in the strip water cooling bag 5 can be conducted to the arc-shaped heat conducting sheets 10, and the heat conducting nails 11 contacted by the outside air can be used for heat dissipation. Heat dissipation, and since the arc-shaped heat-conducting sheet 10 and the heat-conducting nails 11 are evenly arranged and spaced, the bending of the wire body is not affected. At the same time, since five independent strip-shaped water-cooling bags 5 are arranged and each group of heat-dissipating sheaths 4 are relatively short, the bending effect on the wire body is also limited. At the same time, the bending and tensile resistance of the strip-shaped water-cooling bags 5 themselves are improved, and the reliability of the water-cooled pipeline is improved. The combination of multiple groups of heat-dissipating sheaths 4 and the way of being sleeved on the outside of the wire sheath 1 also greatly improves the reliability. When one group of heat-dissipating sheaths 4 is damaged, only this group of heat-dissipating sheaths 4 needs to be removed and replaced, which undoubtedly reduces the overall maintenance difficulty and cost.
[0026] The two adjacent groups of heat dissipation jackets 4 are fixed to each other by fixing the connection holes 12 on the front connection plate 6 and the connection holes 12 on the rear connection plate 7 through the plastic snaps 13 .
[0027] Two adjacent groups of heat dissipation jackets 4 are fixed to each other by fixing the adjacent connecting holes 12 on the front connecting plate 6 and the connecting holes 12 on the rear connecting plate 7 through plastic snaps 13, thereby assembling multiple groups of heat dissipation jackets 4.
[0028] The plastic snaps 13 are used to fix the connection holes 12 of the first side connection plate 8 and the connection holes 12 of the second side connection plate 9 so as to fix the first side connection plate 8 and the second side connection plate 9 together.
[0029] The plastic snaps 13 are used to fix the connection holes 12 of the first side connection plate 8 and the connection holes 12 of the second side connection plate 9 to fix the first side connection plate 8 and the second side connection plate 9 , thereby fixing the heat dissipation sheath 4 to the outside of the wire sheath 1 .
[0030] The front connecting plate 6 and the rear connecting plate 7 are both provided with ventilation holes 14 , and ventilation slots 15 are provided between two adjacent groups of strip-shaped water cooling bags 5 .
[0031] Due to the provision of the ventilation holes 14, air flow can enter the interior of the heat dissipation jacket 4 and flow in the ventilation slots 15. Heat exchange is performed between the air and the heat in the cooling water in the strip water cooling bag 5 and the heat conducted into the heat dissipation jacket 4, thereby taking away part of the heat.
[0032] The working principle and use process of the utility model: the device enhances the heat dissipation of the wire body through the heat dissipation sheath 4. During installation, the heat dissipation sheath 4 is put on the outer side of the wire sheath 1 through the side opening, and the two adjacent groups of heat dissipation sheaths 4 are fixed between the connection holes 12 on the adjacent front connecting plate 6 and the connection holes 12 on the rear connecting plate 7 by the plastic snaps 13, so as to assemble multiple groups of heat dissipation sheaths 4, and the first side connecting plate 8 and the second side connecting plate 9 are fixed by the plastic snaps 13 between the connection holes 12 of the first side connecting plate 8 and the connection holes 12 of the second side connecting plate 9, so as to fix the heat dissipation sheath 4 to the outer side of the wire sheath 1. When the wire body transmits current through the wire core 2, the generated heat is conducted to the strip water cooling bag 5 through the wire sheath 1, and the heat is effectively absorbed by the cooling water in the strip water cooling bag 5. Since the ventilation holes 14 are provided, the airflow can enter the interior of the heat dissipation sheath 4 and flow in the ventilation grooves 15. The air exchanges heat with the heat in the cooling water in the strip water-cooling bag 5 and the heat conducted to the heat dissipation jacket 4, and can take away part of the heat. At the same time, due to the evenly arranged arc-shaped heat-conducting sheets 10 and heat-conducting nails 11, the heat in the strip water-cooling bag 5 can be conducted to the arc-shaped heat-conducting sheets 10, and the heat is dissipated due to the heat-conducting nails 11 contacted by the outside air. Since the arc-shaped heat-conducting sheets 10 and the heat-conducting nails 11 are evenly arranged and spaced, the bending of the wire body is not affected. At the same time, since five independent strip water-cooling bags 5 are provided, and the length of each group of heat-dissipating jackets 4 is relatively short, the bending effect on the wire body is also limited. At the same time, the bending and tensile resistance of the strip water-cooling bag 5 itself is improved, and the reliability of the water-cooled pipeline is improved. The combination of multiple groups of heat-dissipating jackets 4 and the way of being sleeved on the outside of the wire sheath 1 also greatly improves the reliability. When a group of heat-dissipating jackets 4 is damaged, only this group of heat-dissipating jackets 4 needs to be removed and replaced, which undoubtedly reduces the overall maintenance difficulty and cost.
