Description

Technical Field

[0001] This utility model relates to the field of power cabinet technology, and in particular to a power cabinet based on heat dissipation and copper busbar layout. Background Technology

[0002] In the fields of power electronics and new energy storage, power cabinets are key equipment that integrate core components such as batteries, converters, and control units. High power density operation causes a large amount of Joule heat to be generated by current-carrying components such as copper busbars inside the cabinet. If the heat cannot be dissipated in time, it will cause heat accumulation, resulting in local overheating of the equipment, thereby reducing operating efficiency, accelerating component aging, and even causing safety hazards.

[0003] To promote the development of new energy, the main focus is on addressing the current social pain points of power supply cabinets: firstly, heat accumulation causes overheating; secondly, the current carrying capacity of copper busbars with the same cross-sectional area is weak, resulting in high manufacturing costs; thirdly, high self-consumption of electricity increases operating costs; and fourthly, the performance is affected by the diurnal temperature variation. Utility Model Content

[0004] The purpose of this utility model is to provide a power cabinet based on heat dissipation and copper busbar layout. It mainly adopts the principles of photovoltaic cooling and centralized copper busbar heat dissipation, which greatly improves the operating efficiency and stability of the power cabinet, reduces manufacturing and operating costs, and improves user experience. By using a power cabinet based on heat dissipation and copper busbar layout, problems such as heat accumulation, poor stability, and high manufacturing and operating costs are solved.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A power cabinet based on heat dissipation and copper busbar layout includes a cabinet body, a front door, a rear door, a base, front door air intake mesh, right side air intake mesh, left side air intake mesh, rear door exhaust louvers, cabinet air intake chamber, cabinet copper busbar chamber, cabinet exhaust chamber, air intake chamber and copper busbar chamber partition, copper busbar chamber and exhaust chamber lower partition, copper busbar chamber and exhaust chamber upper partition, solar panel, semiconductor, and fan; the front door is installed at the front of the cabinet body, the rear door is installed at the rear of the cabinet body, the base is installed at the bottom of the cabinet body, and the top of the cabinet body is equipped with... Equipped with solar panels to power the fans and semiconductors, the lower half of the front door features a front door air intake grille, while the cabinet has right and left air intake grilles on either side of the front door. The upper half of the rear door has rear door exhaust louvers. The cabinet contains air intake chambers, copper busbar chambers, and exhaust chambers. The air intake chambers and copper busbar chambers are located at the bottom of the cabinet, while the exhaust chamber is located above the copper busbar chambers. Air enters through the front door air intake grille, right side air intake grille, and left side air intake grille. Air enters the cabinet's air intake chamber through the suction mesh. The air intake chamber and the copper busbar chamber are separated by a partition. A gap exists between the partition and the bottom of the cabinet. After being drawn into the air intake chamber, air enters the copper busbar chamber through this gap. A semiconductor is installed at the bottom of the copper busbar chamber, with its cooling side facing the chamber and its heating side facing outwards. Several fans are located on the outside of the exhaust chamber. The air after heat exchange... The air enters the cabinet exhaust chamber from the top of the copper busbar compartment, and is actively drawn out by the fan and discharged through the exhaust louvers at the rear door. The copper busbar compartment and the exhaust chamber are separated by a lower partition and an upper partition. The lower partition separates the air in the lower half of the copper busbar compartment and the exhaust chamber. The upper partition has perforations to allow the heat-exchanged air to be discharged into the exhaust chamber, forming an S-shaped channel for copper busbar heat dissipation from the air intake to the exhaust outlet.

[0007] Compared with existing technologies, this utility model has the following advantages: This utility model mainly adopts principles such as photovoltaic cooling and centralized copper busbar heat dissipation, which greatly improves the operating efficiency and stability of the power cabinet, reduces manufacturing and operating costs, and enhances user experience. It uses a power cabinet based on heat dissipation and copper busbar layout, solving problems such as heat accumulation, poor stability, and high manufacturing and operating costs. It significantly improves the operating efficiency and stability of the power cabinet and reduces manufacturing and operating costs. The use of a fan to provide kinetic energy and an S-shaped heat dissipation channel greatly increases the contact area between the copper busbar and the air, resulting in more efficient heat exchange. Furthermore, semiconductor temperature control ensures that the copper busbar is at a suitable temperature for overcurrent during operation, greatly improving its overcurrent capacity and thus reducing its cost.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] A power cabinet based on heat dissipation and copper busbar layout includes a cabinet body 1, a front door 2, a rear door 3, a base 4, a front door air intake mesh 5, a right side air intake mesh 6, a left side air intake mesh 7, a rear door exhaust louver 8, a cabinet air intake chamber 9, a cabinet copper busbar chamber 10, a cabinet exhaust chamber 11, a partition 12 between the air intake chamber and the copper busbar chamber, a lower partition 13 between the copper busbar chamber and the exhaust chamber, an upper partition 14 between the copper busbar chamber and the exhaust chamber, a solar panel 15, a semiconductor 16, and a fan 17; the front door 2 is installed at the front of the cabinet body 1, the rear door 3 is installed at the rear of the cabinet body 1, the base 4 is installed at the bottom of the cabinet body 1, and a solar panel 17 is installed at the top of the cabinet body 1. The solar panel 15 has a front door air intake mesh 5 installed on the lower half of the front door 2. The cabinet 1 has a right-side air intake mesh 6 and a left-side air intake mesh 7 installed on both sides of the front door. The upper half of the rear door 3 has a rear door exhaust louver 8. Air enters the cabinet's air intake chamber 9 through the front door air intake mesh 5, the right-side air intake mesh 6, and the left-side air intake mesh 7. The cabinet's air intake chamber 9 and the cabinet's copper busbar chamber 10 are separated by the air intake chamber and copper busbar chamber partition 12. A gap is left between the air intake chamber and copper busbar chamber partition 12 and the bottom of the cabinet 1. After air is drawn into the cabinet's air intake chamber 9, it exits through the air intake chamber and copper busbar chamber partition 12 and the bottom of the cabinet 1. The air entering the copper busbar compartment 10 of the cabinet enters through the gap between the bottom sections. A semiconductor 16 is installed at the bottom of the copper busbar compartment 10, with its cooling side facing the compartment and its heating side facing the outside of the cabinet. The semiconductor 16 is powered by a solar panel 15. This allows the air entering the copper busbar compartment 10 to be cooled to a suitable temperature for copper busbar flow by the semiconductor 16, greatly improving the copper busbar flow capacity. The air rises from the bottom of the copper busbar compartment 10, cooling the copper busbars along its path and preventing overheating damage. The cooled air then enters the cabinet exhaust system from the top of the copper busbar compartment 10. The air in compartment 11 is actively drawn out by fan 17 and discharged through the rear door exhaust louvers 8. However, the copper busbar compartment 10 and the exhaust compartment 11 are separated by the lower partition 13 and the upper partition 14 of the copper busbar compartment and exhaust compartment. The lower partition 13 of the copper busbar compartment and exhaust compartment separates the lower half of the air in the copper busbar compartment 10 and the exhaust compartment 11. The upper partition 14 of the copper busbar compartment and exhaust compartment has mesh holes for discharging the heat-exchanged air into the exhaust compartment 11, forming an S-shaped channel for copper busbar heat dissipation from the air intake to the exhaust outlet, which greatly increases the contact surface between the copper busbar and the air, making the heat exchange efficiency more efficient.

[0015] The working principle of this utility model is as follows: Fan 17 draws in ambient air in front of cabinet 1 into cabinet 1, which then flows through the copper busbar compartment 10 of cabinet 1. After the cold air exchanges heat with the copper busbar, it is discharged from the external environment behind cabinet 1, forming an S-shaped heat dissipation path of copper busbar. The semiconductor 16 at the bottom of the copper busbar compartment 10 of cabinet 10 cools the ambient air drawn into the copper busbar compartment 10 of cabinet 10, turning the ambient air into cold air.

[0016] During the daytime, the ambient air temperature is high, which causes poor heat dissipation of the copper busbars in the copper busbar compartment 10 of the cabinet. At this time, the solar panel 15 provides power to the fan 17 and the semiconductor 16 under sunlight, so that the ambient air is converted into cold air when it is drawn into the copper busbar compartment 10 of the cabinet, which dissipates heat from the copper busbars in the copper busbar compartment 10 of the cabinet.

[0017] When the ambient air temperature is low during the day and night, the air entering the copper busbar compartment 10 is cold air, which is beneficial for heat dissipation of the copper busbars inside the compartment 10. At this time, the semiconductor 16 does not work, and the fan 17 continues to work using AC power to dissipate heat from the copper busbars inside the compartment 10. Conversely, when the temperature is too cold, the semiconductor 16 uses AC power to convert the cooling surface into the heating surface to heat the copper busbar compartment 10.

[0018] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
