Description

Technical Field

[0001] This invention relates to the field of electrical cable tray technology, and in particular to a cabinet-type heat dissipation cable tray. Background Technology

[0002] Traditional cable trays consist of U-shaped channels (or U-shaped trays) with covered plates sealing the openings, forming the cable routing channels. In energy storage systems, vertical cable trays, often spliced ​​from multiple sections (due to bends or the transformer's height), are frequently used between the transformer and the PCS cabinet. Copper busbars, running from the top of the transformer to the bottom of the PCS cabinet, are laid within these vertical cable trays. In this configuration, the vertical cable tray is sandwiched between the transformer and the PCS cabinet. When the copper busbars within the vertical cable tray require maintenance, the covers of multiple sections of the vertical cable tray must be removed. However, the limited operating space between the transformer and the PCS cabinet makes this disassembly extremely difficult.

[0003] Furthermore, because the vertical cable trays are sandwiched between the transformer and the PCS cabinet, they receive heat from both simultaneously. Additionally, the copper busbars inside the vertical cable trays also generate heat when energized, resulting in a high demand for heat dissipation. However, due to their sandwiched location, the vertical cable trays have limited space for heat dissipation. The only options are to create openings in the cable trays or install louvers for natural ventilation, but this results in a small heat dissipation area and low convection efficiency, far from meeting the required cooling capacity. Summary of the Invention

[0004] To address the aforementioned shortcomings, the present invention aims to provide a cabinet-type heat dissipation cable tray, which solves the problems of difficult maintenance of cables or copper busbars laid inside traditional cable trays, as well as the inability of traditional cable trays to dissipate heat.

[0005] To achieve this objective, the present invention adopts the following technical solution: A cabinet-type heat dissipation cable tray includes a cable tray cabinet, a first heat dissipation component, a second heat dissipation component, and a third heat dissipation component; a cable routing port is provided at the top rear of the cable tray cabinet, and a cable routing channel is provided at the bottom front of the cable tray cabinet; the left or right cabinet wall of the cable tray cabinet is provided as an openable door, or both the left and right cabinet walls of the cable tray cabinet are provided as openable doors. The first heat dissipation component is disposed on the front wall of the cable tray cabinet, and the first heat dissipation component occupies at least 50% of the area of ​​the front wall of the cable tray cabinet; The second heat dissipation component is disposed on the left cabinet wall of the cable tray cabinet, and the second heat dissipation component occupies at least 50% of the area of ​​the left cabinet wall of the cable tray cabinet; The third heat dissipation component is disposed on the right wall of the cable tray cabinet, and the third heat dissipation component occupies at least 50% of the area of ​​the right wall of the cable tray cabinet. The first heat dissipation component, the second heat dissipation component, and the third heat dissipation component are all provided with fin groups inside and outside the cable tray cabinet; the first heat dissipation component, the second heat dissipation component, and the third heat dissipation component are all used for heat conduction between the inside of the cable tray cabinet and the outside.

[0006] Furthermore, the left and right sides of the cable tray cabinet are of equal width, and the front width of the cable tray cabinet is greater than the area of ​​the left side.

[0007] Furthermore, the first heat dissipation component includes at least one first finned heat sink, and the front cabinet wall of the bridge rack cabinet has at least one first mounting opening from left to right, and the first finned heat sink is installed in the first mounting opening one by one. The second heat dissipation component includes at least one second finned heat sink. The left cabinet wall of the cable tray cabinet has at least one second mounting opening from front to back, and the second finned heat sink is installed in the second mounting opening one by one. The third heat dissipation component includes at least one third finned heat sink. The right wall of the cable tray cabinet has at least one third mounting port from front to back, and the third finned heat sink is installed in the third mounting port one by one.

[0008] Furthermore, the height of the first finned radiator, the second finned radiator, and the third finned radiator is at least 50% of the height of the cable tray cabinet.

[0009] Furthermore, the first finned radiator, the second finned radiator, and the third finned radiator have the same structure; The third finned radiator includes two heat dissipation plates with fin groups on one side; the fin groups of the two heat dissipation plates face outward and are attached back to back, and the edges of the two heat dissipation plates are connected in series to the edge of the third mounting port, the first mounting port or the second mounting port by fasteners, one of the heat dissipation plates has its fin group passing through the third mounting port, the first mounting port or the second mounting port and facing outward from the cable tray cabinet, and the other heat dissipation plate has its fin group located inside the cable tray cabinet.

[0010] Furthermore, a strip-shaped mounting base is provided on the inner side of the front cabinet wall of the cable tray cabinet; The strip-shaped mounting base is located to the left of the first mounting port on the far left, and the strip-shaped mounting base is parallel to the left side of the first mounting port; The strip mounting base is also disposed to the right of the first mounting port on the far right, and the strip mounting base is parallel to the right side of the first mounting port. The strip-shaped mounting base is also disposed above the first mounting opening, and the strip-shaped mounting base is parallel to the upper side of the first mounting opening; The strip-shaped mounting base is also disposed below the first mounting opening, and the strip-shaped mounting base is parallel to the lower edge of the first mounting opening; The rear end face of the strip mounting base is higher than the fin group of the heat sink. At least one cable limiting component is installed on the rear end face of the strip mounting base. The cable limiting component is used to limit the copper busbar or cable behind the fin group of the heat sink.

[0011] Furthermore, the cable limiting assembly includes a first limiting strip, a second limiting strip, and at least one connecting rod; the first limiting strip is fixed parallel to the rear end face of the strip mounting base above or below, or the first limiting strip spans across the rear end face of the strip mounting base fixed to the left and right rear sides; The second limiting strip is parallel to the first limiting strip, and the connecting rods are spaced apart along the length direction of the first limiting strip. The front end of the connecting rod is fixedly connected to the first limiting strip, and the rear end of the connecting rod is fixedly connected to the second limiting strip. A threading channel is formed between the first limiting strip and the second limiting strip.

[0012] Furthermore, the width of the left and right sides of the cable tray cabinet is 1.5 to 3 times the width of the copper busbar.

[0013] Furthermore, the top surface of the cable tray cabinet is an inclined surface that slopes from left to right, from right to left, or from the middle to the left and right respectively.

[0014] Furthermore, the top periphery of the cable tray cabinet is provided with at least one pair of opposing lifting rings.

[0015] The technical solution provided by this invention can include the following beneficial effects: After opening a cable routing port at the top rear of the cable tray cabinet and a cable routing channel at the bottom front of the cabinet, the rear of the cable tray cabinet is close to the transformer. The front end of the cable routing channel is connected to the cable routing port of the PCS cabinet. The copper busbar can enter the cable routing port from the top of the transformer, be laid inside the cable tray cabinet, and enter the PCS cabinet through the cable routing channel to complete the electrical connection between the transformer and the PCS cabinet. At this time, the left and right sides of the cable tray cabinet are not blocked by the transformer and the PCS cabinet. One or both of the left and right cabinet walls of the cable tray cabinet can be set as openable doors. In this way, when the copper busbar inside the cable tray cabinet needs maintenance, it can be directly opened for inspection and maintenance, which is convenient and quick.

[0016] Furthermore, due to the irregular surface of the transformer, it is difficult to reserve space for heat dissipation. Therefore, only a cable tray inlet is needed at the rear of the cable tray cabinet near the transformer wiring. The front of the cable tray cabinet and the PCS cabinet are parallel, so a cable tray channel is set at the front of the cabinet to connect to the cable tray inlet of the PCS cabinet. This cable tray channel limits the space between the front of the cable tray cabinet and the PCS cabinet, leaving a gap for heat dissipation. As a result, there is space for natural airflow on the front, left, and right sides of the cable tray cabinet. Therefore, the first, second, and third heat dissipation components are respectively set on the front, left, and right walls of the cable tray cabinet (or on the doors if they are designed to open), occupying at least % of the area. This ensures that the heat dissipation components efficiently conduct heat from inside the cable tray cabinet to the outside, meeting the heat dissipation requirements of the cable tray cabinet. Moreover, the heat dissipation components have fins set both inside and outside the cabinet, which fully contact the airflow inside and outside the cabinet, accelerating heat absorption and dissipation, further improving heat dissipation efficiency.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0028] The following is combined with Figures 1 to 6 This describes a cabinet-type heat dissipation bridge according to an embodiment of the present invention.

[0029] A cabinet-type heat dissipation cable tray includes a cable tray cabinet 1, a first heat dissipation component 2, a second heat dissipation component 3, and a third heat dissipation component 4; a cable routing port 11 is provided at the top rear of the cable tray cabinet 1, and a cable routing channel 12 is provided at the bottom front of the cable tray cabinet 1; the left or right cabinet wall of the cable tray cabinet 1 is provided as an openable door, or both the left and right cabinet walls of the cable tray cabinet 1 are provided as openable doors. The first heat dissipation component 2 is disposed on the front wall of the cable tray cabinet 1, and the first heat dissipation component 2 occupies at least 50% of the area of ​​the front wall of the cable tray cabinet 1. The second heat dissipation component 3 is disposed on the left wall of the cable tray cabinet 1, and the second heat dissipation component 3 occupies at least 50% of the area of ​​the left wall of the cable tray cabinet 1. The third heat dissipation component 4 is installed on the right wall of the cable tray cabinet 1, and the third heat dissipation component 4 occupies at least 50% of the area of ​​the right wall of the cable tray cabinet 1. The first heat dissipation component 2, the second heat dissipation component 3, and the third heat dissipation component 4 are all provided with fin groups inside and outside the cable tray cabinet 1, respectively; the first heat dissipation component 2, the second heat dissipation component 3, and the third heat dissipation component 4 are all used for heat conduction between the inside and outside of the cable tray cabinet 1.

[0030] In a preferred embodiment of the cabinet-type heat dissipation bridge proposed in this invention, such as... Figure 1 and 2 As shown, after a cable tray cabinet 1 has a cable routing port 11 at the top rear and a cable routing channel 12 at the bottom front, the cable tray cabinet 1 is located close to the transformer at the rear. The front end of the cable routing channel 12 connects to the cable routing port of the PCS cabinet. The copper busbars can then enter the cable routing port 11 from the top of the transformer, be laid inside the cable tray cabinet 1, and enter the PCS cabinet through the cable routing channel 12, thus completing the electrical connection between the transformer and the PCS cabinet. At this time, the left and right sides of the cable tray cabinet 1 are not blocked by the transformer and the PCS cabinet. One or both of the left and right cabinet walls of the cable tray cabinet 1 can be made into openable doors. This way, when the copper busbars inside the cable tray cabinet 1 need maintenance, the door can be opened directly for inspection, which is convenient and quick.

[0031] Furthermore, due to the irregular surface of the transformer, it is difficult to reserve space for heat dissipation. Therefore, only a cable tray port 11 is provided at the rear of the cable tray cabinet 1, which is close to the transformer wiring. Since the front of the cable tray cabinet 1 and the cabinet surface of the PCS cabinet are parallel, a cable routing channel 12 is provided at the front of the cabinet to connect to the cable tray port of the PCS cabinet. This cable routing channel 12 limits the space between the front of the cable tray cabinet 1 and the cabinet surface of the PCS cabinet, thus maintaining a heat dissipation gap. It can be seen that there is space for natural air on the front, left, and right outer sides of the cable tray cabinet 1. Since the airflow is flowing through, the first heat dissipation component 2, the second heat dissipation component 3, and the third heat dissipation component 4 are respectively installed on the front, left, and right walls of the cable tray cabinet 1 (or on the door if it is made into an openable door), and occupy at least 50% of the area. This ensures that the heat dissipation components can efficiently conduct the heat inside the cable tray cabinet 1 to the outside of the cabinet, meeting the heat dissipation requirements of the cable tray cabinet 1. In addition, the heat dissipation components can fully contact the airflow inside and outside the cabinet through the fin groups set in both directions, which can accelerate the absorption and discharge of heat and further improve the heat dissipation efficiency.

[0032] Furthermore, the left and right sides of the cable tray cabinet 1 are of equal width, and the front width of the cable tray cabinet 1 is greater than the area of ​​the left side.

[0033] In this embodiment, the width of the front of the cable tray cabinet 1 is greater than the width of the left and right sides. When there are many copper busbars laid inside the cable tray cabinet 1, the copper busbars can be arranged from the left side to the right side of the cable tray cabinet 1 to shorten the width between the front and back of the cable tray cabinet 1 as much as possible, that is, to minimize the distance between the transformer and the PCS cabinet, and to avoid the entire energy storage system occupying too much building area.

[0034] Furthermore, the first heat dissipation component 2 includes at least one first finned heat sink 21, and the front cabinet wall of the bridge cabinet 1 has at least one first mounting port 13 from left to right, and the first finned heat sink 21 is installed in the first mounting port 13 one by one. The second heat dissipation component 3 includes at least one second finned heat sink 31. The left cabinet wall of the bridge cabinet 1 has at least one second mounting port 14 from front to back, and the second finned heat sink 31 is installed in the second mounting port 14 one by one. The third heat dissipation component 4 includes at least one third finned heat sink 41. The right cabinet wall of the bridge cabinet 1 has at least one third mounting port 15 from front to back, and the third finned heat sink 41 is installed in the third mounting port 15 one by one.

[0035] In this embodiment, Figure 3 Taking the right wall of the cable tray cabinet 1 as an example, the installation and composition of the first heat dissipation component 2, the second heat dissipation component 3 and the third heat dissipation component 4 are the same. They are all installed by at least one finned heat sink in the mounting port on the cabinet wall, so that the finned heat sink can connect the internal and external spaces of the cabinet and dissipate heat quickly through the fins.

[0036] It should be noted that the number of the first finned radiator 21, the second finned radiator 31, and the third finned radiator 41 is determined according to the actual selection. When a single finned radiator can occupy 50% or more of the cabinet wall area, only one is required; otherwise, the number of finned radiators should be increased accordingly.

[0037] Furthermore, the height of the first finned radiator 21, the second finned radiator 31, and the third finned radiator 41 is at least 50% of the height of the cable tray cabinet 1.

[0038] In this embodiment, in order for the first heat dissipation component 2, the second heat dissipation component 3, and the third heat dissipation component 4 to occupy 50% or more of the cabinet wall area, when the first finned radiator 21, the second finned radiator 31, and the third finned radiator 41 are all arranged horizontally, the height of the first finned radiator 21, the second finned radiator 31, and the third finned radiator 41 must be at least 50% of the height of the cable tray cabinet 1.

[0039] Furthermore, the first finned radiator 21, the second finned radiator 31, and the third finned radiator 41 have the same structure. The third finned radiator 41 includes two heat sinks 411 with fin groups on one side; the fin groups of the two heat sinks 411 face outward and are attached back to back, and the edges of the two heat sinks 411 are connected and fixed to the edges of the third mounting port 15, the first mounting port 13 or the second mounting port 14 by fasteners. The fin group of one heat sink 411 passes through the third mounting port 15, the first mounting port 13 or the second mounting port 14 and faces outward from the cable tray cabinet 1, while the fin group of the other heat sink 411 is located inside the cable tray cabinet 1.

[0040] In this embodiment, as Figure 3 and 4 As shown, taking the third finned heat sink 41 as an example, the finned heat sink is designed to achieve bidirectional fin arrangement inside and outside the cabinet. The finned heat sink consists of two heat sinks 411 with fins on one side, with the fins facing outward and back to back. The edges of the two heat sinks 411 are connected and fixed to the edge of the third mounting port 15 (or the first mounting port 13, or the second mounting port 14) by fasteners (such as screws). The fins of one heat sink 411 pass through the third mounting port 15 (or the first mounting port 13, or the second mounting port 14) and face outward from the cable tray cabinet 1, while the fins of the other heat sink 411 face inward from the cable tray cabinet 1. They come into contact with the airflow on both sides through the fins, so that the heat inside the cable tray cabinet 1 can be quickly absorbed by the fins and conducted to the fins on the other side, and quickly released outward from the cable tray cabinet 1, which greatly improves the heat dissipation efficiency.

[0041] Furthermore, a strip mounting base 16 is provided on the inner side of the front cabinet wall of the cable tray cabinet 1; The strip mounting base 16 is located to the left of the leftmost first mounting port 13, and the strip mounting base 16 is parallel to the left side of the first mounting port 13; The strip mounting base 16 is also located to the right of the rightmost first mounting port 13, and the strip mounting base 16 is parallel to the right side of the first mounting port 13. The strip mounting base 16 is also disposed above the first mounting port 13, and the strip mounting base 16 is parallel to the upper edge of the first mounting port 13; The strip mounting base 16 is also disposed below the first mounting port 13, and the strip mounting base 16 is parallel to the lower edge of the first mounting port 13; The rear end face of the strip mounting base 16 is higher than the fin group of the heat sink 411. At least one cable limiting component 5 is installed on the rear end face of the strip mounting base 16. The cable limiting component 5 is used to limit the copper busbar or cable behind the fin group of the heat sink 411.

[0042] In this embodiment, the strip mounting base 16 is arranged to surround all the first mounting ports 13, providing a mounting base for the cable limiting component 5. After the cable limiting component 5 limits the copper busbar or cable, it can route the copper busbar or cable to the fin group (i.e. behind the fin group) of the heat sink 411, so that the heat of the copper busbar or cable can be directly absorbed by the fin group, achieving the effect of rapid heat dissipation of the copper busbar or cable.

[0043] Furthermore, the cable limiting assembly 5 includes a first limiting strip 51, a second limiting strip 53, and at least one connecting rod 52; the first limiting strip 51 is fixed parallel to the rear end face of the upper or lower strip mounting base 16, or the first limiting strip 51 spans across the rear end face of the left and right rear strip mounting base 16. The second limiting bar 53 is parallel to the first limiting bar 51. The connecting rods 52 are spaced apart along the length of the first limiting bar 51. The front end of the connecting rod 52 is fixedly connected to the first limiting bar 51, and the rear end of the connecting rod 52 is fixedly connected to the second limiting bar 53. A threading channel is formed between the first limiting bar 51 and the second limiting bar 53.

[0044] In this embodiment, as Figure 5 and 6 As shown, the first limiting strip 51 is fixed parallel to the rear end face of the strip mounting base 16 above or below, or spans the rear end face of the strip mounting base 16 fixed to the left and right rear, so that the first limiting strip 51 spans the fin group of the heat sink 411; at this time, the first limiting strip 51 is fixed in parallel with the second limiting strip 53 by the connecting rod 52, so that a wire passage is formed between the first limiting strip 51 and the second limiting strip 53, allowing the copper busbar or cable to pass through, thereby limiting the copper busbar or cable.

[0045] Furthermore, the width of the left and right sides of the cable tray cabinet 1 is 1.5 to 3 times the width of the copper busbar.

[0046] In this embodiment, since the operable door is located on the left or right wall of the cable tray cabinet 1, in order to provide sufficient operating space for the staff during maintenance, it is preferable to set the width of the left and right sides of the cable tray cabinet 1 to be 1.5 to 3 times the width of the copper busbar (the specific multiple is determined by the specifications and laying method of the copper busbar; for example, the multiple can be reduced for large copper busbars according to the actual situation). In this way, after the copper busbar is laid, there is still enough width space for the staff to operate.

[0047] Furthermore, the top surface of the cable tray cabinet 1 is an inclined surface that slopes from left to right, from right to left, or from the middle to the left and right respectively.

[0048] In this embodiment, considering that the energy storage system may be installed outdoors, the top surface of the cable tray cabinet 1 is preferably a slope. The type of slope is not limited; it can be a single slope from left to right or from right to left, or it can be as follows: Figure 1 The inclined surfaces in the middle of the top surface, which slope to the left and right respectively, guide rainwater to the left and right sides of the cable tray cabinet 1, preventing rainwater from being diverted to the transformer or PCS cabinet.

[0049] Furthermore, the top periphery of the cable tray cabinet 1 is provided with at least a pair of opposing lifting rings 17.

[0050] In this embodiment, as Figure 1 As shown, since the cable tray cabinet 1 is installed between the transformer and the PCS cabinet, the space is limited and it is not possible to use a forklift for transportation and installation. It is preferable to use at least one pair of opposing lifting rings 17 for hoisting.

[0051] Other components and operations of a cabinet-type heat dissipation bridge according to an embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
