Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to an energy-saving power equipment cabinet. Background Technology

[0002] Power equipment cabinets serve as the core carriers for power grid transmission, new energy grid connection, industrial power distribution, and data center operation and maintenance. They integrate various power devices such as circuit breakers, rectifier modules, distribution busbars, and control units. These devices continuously generate heat during long-term operation, creating a heat load within the cabinet. With the rapid development of power equipment towards integration, higher power, and higher density, the installation density of components within the cabinet has significantly increased, leading to a substantial increase in heat flux density per unit volume. Therefore, heat dissipation has become a key factor restricting the safety, stability, and energy consumption levels of cabinet operation.

[0003] Currently, the main heat dissipation methods for existing power equipment cabinets are three traditional forms: natural convection cooling, forced fan direct cooling, and external air conditioning cooling. These are all heat dissipation methods that cover a large area inside the cabinet, but they lack targeted heat dissipation. In particular, the active cooling method wastes a lot of the airflow it provides, failing to achieve the desired cooling effect, resulting in insufficient heat dissipation efficiency and serious energy waste. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an energy-saving power equipment cabinet that addresses the above-mentioned technical deficiencies. This cabinet can flexibly adjust the layout of the power equipment, provide targeted heat dissipation for the power equipment, improve heat dissipation efficiency, and reduce energy consumption.

[0005] The technical solution adopted in this invention is as follows: An energy-saving power equipment cabinet is provided, comprising a cabinet body, a support plate connected to the top of the cabinet body; a liquid-cooled storage tank fixed to the upper end of the support plate; a radiator correspondingly installed on the outer wall of the liquid-cooled storage tank; a connecting frame fixed to the lower end of the support plate; multiple connecting through holes horizontally through the connecting frame; a cooling installation component corresponding to each connecting through hole on the connecting frame; and a liquid-cooled transmission component corresponding to each cooling installation component on the support plate. The cooling installation assembly includes a package shell that slides through the connecting through hole; a cooling seat for connecting to electrical equipment is fixed at one end of the package shell; a liquid cooling cavity is opened inside the cooling seat; two liquid guide tubes are provided inside the package shell; one end of the liquid guide tube is connected to the liquid cooling cavity, and the other end is sealed and passes through the end of the package shell. The liquid-cooled transfer assembly includes a circulation pump fixed on a support plate and a transfer pipe that passes through and is fixed on the support plate; the outer ends of two liquid guide pipes are respectively connected to one end of the circulation pump and one end of the transfer pipe; the other end of the circulation pump and the other end of the transfer pipe are respectively connected to the bottom of the liquid-cooled storage tank.

[0006] To further optimize this technical solution, an energy-saving power equipment cabinet has an installation opening at the top of its cabinet body; a support plate is rotatably connected within the installation opening.

[0007] To further optimize this technical solution, an energy-saving power equipment cabinet has a base fixed to the outside of its enclosure shell; a positioning screw parallel to the length of the enclosure shell is rotatably connected inside the base; a positioning through hole is provided on the connecting seat; and the positioning screw is threadedly connected to the positioning through hole.

[0008] To further optimize this technical solution, a heat-insulating coating is applied to the inner wall of the enclosure of an energy-saving power equipment cabinet.

[0009] To further optimize this technical solution, the connection surface between the cooling base of an energy-saving power equipment cabinet and the power equipment is made of copper plated with nickel.

[0010] To further optimize this technical solution, a liquid-cooled cavity of an energy-saving power equipment cabinet is sealed with multiple ventilation sleeves; the interior of the ventilation sleeves is separated from the interior of the liquid-cooled cavity; and the cooling seat has through holes that correspond one-to-one with the ventilation sleeves.

[0011] The beneficial effects of this invention are as follows: The liquid-cooled storage tank stores coolant. Through the action of a circulation pump and a passage formed by transfer pipes and guide pipes, the coolant circulates within the liquid-cooled cavity. The flow of coolant within the cavity cools the cooling seat, thereby cooling and dissipating heat from the connected electrical equipment. A radiator, installed on the outer wall of the liquid-cooled storage tank, dissipates the heated coolant, enhancing the continuous cooling capacity of the electrical equipment. The enclosure slides through the connecting through-hole, allowing adjustment of the distance between the cooling seat and the connecting bracket. This alters the positional distribution of different electrical devices, mitigating the problem of severe localized heat accumulation and improving the internal heat dissipation performance of the cabinet.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1-3 As shown, an energy-saving power equipment cabinet includes a cabinet body 1, with a support plate 2 connected to the top of the cabinet body 1; a liquid-cooled storage tank 3 is fixed to the upper end of the support plate 2; a radiator 4 is installed on the outer wall of the liquid-cooled storage tank 3; a connecting frame 5 is fixed to the lower end of the support plate 2; multiple connecting through holes 6 are opened horizontally along the connecting frame 5; cooling installation components corresponding to the connecting through holes 6 are provided on the connecting frame 5; and liquid-cooled transmission components corresponding to the cooling installation components are provided on the support plate 2. The cooling installation assembly includes a packaged shell 7 that slides through the connecting through hole 6; a cooling seat 8 for connecting to power equipment is fixed at one end of the packaged shell 7; a liquid cooling cavity 9 is opened inside the cooling seat 8; two liquid guide tubes 10 are provided inside the packaged shell 7; one end of the liquid guide tube 10 is connected to the liquid cooling cavity 9, and the other end is sealed and passes through the end of the packaged shell 7. The liquid-cooled transmission assembly includes a circulation pump 11 fixed on the support plate 2 and a transmission pipe 12 that passes through and is fixed on the support plate 2; the outer ends of the two liquid guide pipes 10 are respectively connected to one end of the circulation pump 11 and one end of the transmission pipe 12; the other end of the circulation pump 11 and the other end of the transmission pipe 12 are respectively connected to the bottom of the liquid-cooled storage tank 3.

[0016] In this solution, the electrical equipment that requires key heat dissipation is installed on each cooling base 8. Then, by sliding the encapsulation shell 7 in the connecting through hole 6, the position of each electrical equipment from the connecting frame 5 is changed, thereby changing the position distribution of different electrical equipment. This allows the electrical equipment to be staggered in spatial layout, effectively reducing the accumulation of local heat and improving the heat dissipation performance inside the cabinet 1.

[0017] When active cooling is required, the circulation pump 11 is activated. Through the action of the circulation pump 11 and the passage formed by the transmission pipe 12 and the liquid guide pipe 10, the coolant in the liquid-cooled storage tank 3 circulates into the liquid-cooled cavity 9. Through heat exchange, the temperature of the contact surface between the cooling seat 8 and the electrical equipment decreases. Combined with the airflow of passive cooling, the heat generated by the corresponding electrical equipment is effectively carried away, achieving a cooling effect. At the same time, the radiator 4 also functions simultaneously to dissipate heat from the heated coolant, ensuring continuous cooling of the electrical equipment.

[0018] Compared to traditional methods of large-area and widespread heat dissipation, this solution adopts a precise cooling and heat dissipation method for each electrical device, which effectively improves the energy utilization rate used for cooling and has outstanding energy-saving effect.

[0019] like Figure 2 As shown, the top of the cabinet 1 has an installation opening 13; the support plate 2 is rotatably connected in the installation opening 13.

[0020] The rotation of the support plate 2 can drive the connecting frame 5 to rotate, which in turn drives the cooling installation components to rotate, further enhancing the flexibility of the electrical equipment arrangement within the cabinet 1. This helps to adjust the electrical equipment to a more convenient angle for heat dissipation and also facilitates the installation and disassembly of the electrical equipment.

[0021] like Figure 3 As shown, a base 14 is fixed to the outside of the encapsulation shell 7; a positioning screw 15 parallel to the length direction of the encapsulation shell 7 is rotatably connected inside the base 14; a positioning through hole 16 is provided on the connecting seat; the positioning screw 15 is threadedly connected to the positioning through hole 16.

[0022] By connecting the positioning screw 15 to the positioning through hole 16, it is easy to adjust the degree of insertion of the encapsulation shell 7 along the connecting through hole 6, and it can also be fixed to the connecting frame 5, making the installation of power equipment more stable.

[0023] The inner wall of the enclosure 7 is coated with a heat-insulating coating. The heat-insulating coating can block heat conduction and reduce the amount of irrelevant heat absorbed by the coolant before it flows into the liquid-cooled cavity 9.

[0024] The connection surface between the cooling base 8 and the power equipment is made of copper with nickel plating to ensure high efficiency of heat conduction, as well as rust prevention and durability.

[0025] like Figure 3-4 As shown, multiple ventilation sleeves 17 are sealed and connected inside the liquid-cooled cavity 9; the interior of the ventilation sleeves 17 is separate from the interior of the liquid-cooled cavity 9; the cooling base 8 has through holes 18 that correspond one-to-one with the ventilation sleeves 17. The ventilation sleeves 17 and the through holes 18 facilitate airflow to the electrical equipment, improving the airflow cooling effect during passive heat dissipation.

Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention.
