Description

Technical Field

[0001] This utility model relates to the field of power supply technology, and in particular to a high-power control power supply for use in mining machinery. Background Technology

[0002] Mining machinery refers to equipment directly used in mineral extraction and beneficiation operations. It includes both mining machinery and mineral processing machinery. The working principles and structures of prospecting machinery are largely the same or similar to those of mining machinery used for extracting the same types of minerals; broadly speaking, prospecting machinery also belongs to the category of mining machinery. In addition, a large number of cranes, conveyors, ventilation fans, and drainage machinery are used in mining operations. During the use of machinery, as the depth of the mine increases, the gravity and friction forces that machinery such as cranes and hoists need to overcome also increase, and the required power will increase accordingly. Similarly, the greater the weight being lifted, the higher the power output required by the hoist, enabling it to obtain more energy to overcome the weight of the object. Furthermore, increasing power is also necessary to improve work efficiency.

[0003] Current high-power mining machinery can reach thousands of kilowatts in power, resulting in large current flows and significant heat generation. This can easily lead to overheating of the machinery's internal temperature, especially the control power supply connected to external power sources. If the temperature gets too high, it will stop supplying power to the machinery, affecting work efficiency. However, the heat dissipation performance of current high-power control power supplies in mining machinery is poor, failing to dissipate heat effectively and causing their internal temperatures to rise excessively, leading to power outages. Therefore, it is necessary to improve existing high-power control power supplies used in mining machinery. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide a high-power control power supply for mining machinery. This power supply effectively solves the problem that existing high-power control power supplies for mining machinery have poor heat dissipation performance, cannot dissipate heat in time, and are prone to overheating, causing them to stop supplying power to the machinery and affecting production efficiency.

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

[0006] A high-power control power supply for mining machinery includes a housing, a control module, a wiring harness, a USB interface, and a liquid cooling pipe. The housing has a receiving cavity with a mounting position inside, and multiple heat dissipation fins are disposed on the top of the housing, each fin being coated with a graphene layer. The control module is disposed on the mounting position. The wiring harness is disposed on the housing and connected to the control module. The USB interface is disposed on the housing and connected to the control module. The liquid cooling pipe includes an integrally formed liquid inlet, a first liquid cooling section, and an outlet, both of which extend outward from the housing. The first liquid cooling section is located within the receiving cavity and surrounds the periphery of the mounting position.

[0007] As a preferred embodiment, the liquid cooling pipe further includes a second liquid cooling section, which is integrally formed and connected to the first liquid cooling section, and the second liquid cooling section surrounds the edge of the accommodating cavity.

[0008] As a preferred embodiment, the surface of the graphene layer is rough.

[0009] As a preferred embodiment, the plurality of heat dissipation fins are arranged in a matrix on the top of the housing.

[0010] As a preferred embodiment, all of the multiple heat dissipation fins are provided with reinforcing ribs.

[0011] As a preferred embodiment, the accommodating cavity has a heat dissipation position located between the mounting position and the first liquid cooling section.

[0012] As a preferred embodiment, the outer casing is provided with a plurality of heat dissipation holes, which are connected to the accommodating cavity.

[0013] As a preferred option, the inner diameter of each heat dissipation hole gradually decreases from the inside to the outside.

[0014] As a preferred embodiment, a dustproof mesh is provided at the outer end of the heat dissipation hole.

[0015] As a preferred embodiment, all peripheral surfaces of the outer casing are roughened.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0017] By setting multiple heat dissipation fins on the top of the housing, and coating the surface of each heat dissipation fin with a graphene layer, the heat dissipation capacity of the housing is effectively improved. In addition, liquid cooling pipes are set, with the first liquid cooling section located inside the accommodating cavity and surrounding the periphery of the mounting position. This design allows the first liquid cooling section to remove the heat from the electronic components on the control module in a timely manner, preventing the temperature inside the housing from becoming too high and avoiding the control power supply from stopping the power supply to the machinery, so as to maintain high production efficiency.

[0033] Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a housing 10, a control module 20, a wiring harness 30, a USB interface 40, and a liquid cooling pipe 50.

[0034] The outer casing 10 has a receiving cavity 11, within which a mounting position 12 is provided. Multiple heat dissipation fins 13 are disposed on the top of the outer casing 10, and the surfaces of these fins 13 are coated with a graphene layer 131. In this embodiment, the surface of the graphene layer 131 is roughened, which increases the contact area between the graphene layer 131 and the outside air, facilitating heat transfer and allowing for faster heat dissipation. The multiple heat dissipation fins 13 are arranged in a matrix on the top of the outer casing 10, and each fin 13 is provided with reinforcing ribs 132. Furthermore, the receiving cavity 11 has a heat dissipation position 14 located between the mounting position 12 and the first liquid cooling section 52, which is used to install a heat sink or other heat dissipation device. A hot air fan effectively improves heat dissipation performance; the outer casing 10 has multiple heat dissipation holes 15, which are connected to the accommodating cavity 11. The inner diameter of each heat dissipation hole 15 gradually decreases from the inside to the outside. This design allows the temperature inside the outer casing 10 to rise. When the gas inside the casing expands and flows outward, the rate of passage through the heat dissipation hole 15 gradually increases, and the smaller outer opening reduces the entry of dust; a dustproof mesh (not shown in the figure) is provided at the outer end of the heat dissipation hole 15; and the peripheral surfaces of the outer casing 10 are all rough surfaces; specifically, the outer casing 10 includes an upper casing 101 and a lower casing 102. The aforementioned mounting position 12 and heat dissipation position 14 are both opened in the lower casing 102, and the upper casing 101 and the lower casing 102 are joined together to form the accommodating cavity 11.

[0035] The control module 20 is mounted on the mounting position 12; the wiring harness 30 is mounted on the housing 10 and connected to the control module 20; the USB interface 40 is mounted on the housing 10 and connected to the control module 20; in this embodiment, the wiring harness 30 includes multiple wiring harnesses 31, which can be AC ​​connection cables, CAN communication cables, battery connection cables or other data connection cables, etc.

[0036] The liquid cooling pipe 50 includes an integrally formed liquid inlet 51, a first liquid cooling section 52, and an outlet 53. Both the liquid inlet 51 and the outlet 53 extend outward from the outer casing 10. The first liquid cooling section 52 is located within the accommodating cavity 11 and surrounds the periphery of the mounting position 12. The closer it is to the mounting position 12, the more heat it absorbs from the control module mounted on the mounting position 12 and the faster it carries away the heat, significantly improving heat dissipation performance. In this embodiment, the liquid cooling pipe 50 also includes a second liquid cooling section 54, which is integrally formed with the first liquid cooling section 52 and surrounds the edge of the accommodating cavity 11. This design not only carries away the heat from the accommodating cavity 12 but also transfers the heat from the accommodating cavity 12 to the outer casing 10, and then through the outer casing 10 to the outside, further improving heat dissipation capacity.

[0037] The working process of this embodiment is described in detail below:

[0038] First, connect the inlet 51 and outlet 53 of the liquid cooling pipe 50 to an external liquid cooling device. Then, start the mining machinery, the control power supply starts working, the electronic components on the control module 20 gradually start to heat up, and the liquid cooling pipe 50 starts to circulate coolant to carry away the heat from the control power supply.

[0039] The key design feature of this invention is that by providing multiple heat dissipation fins on the top of the outer casing, and coating the surface of each heat dissipation fin with a graphene layer, the heat dissipation capacity of the outer casing is effectively improved. In addition, a liquid cooling pipe is provided, with the first liquid cooling section located inside the accommodating cavity and surrounding the periphery of the mounting position. This design allows the first liquid cooling section to promptly remove the heat from the electronic components on the control module, preventing the temperature inside the casing from becoming too high and avoiding the control power supply from stopping to supply power to the machinery, thereby maintaining high production efficiency.

[0040] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
