Description

Technical Field

[0001] The utility model belongs to the technical field of charging piles, in particular to a multi-directional heat dissipation system for charging piles. Background Art

[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle charging facilities, are devices that provide electricity to charge electric vehicles (EVs). With the rapid development of the electric vehicle industry, the construction and popularization of charging piles have become increasingly important. They provide electric vehicle users with the necessary energy supply and support the daily use and long-distance travel of electric vehicles. Among them, the heat dissipation of charging piles is an important engineering issue because charging piles generate heat when working, especially when providing fast charging services. If the heat cannot be dissipated effectively, it may cause the internal temperature of the charging pile to rise, affecting the performance and life of the equipment, and may even cause safety problems. Therefore, the design and manufacture of charging piles need to consider efficient heat dissipation solutions.

[0003] For example, the Chinese patented heat pipe fin composite heat dissipation type charging pile heat dissipation system, patent number CN202011187296.4, includes an outer box, a charging module shell fixed in the outer box, and charging components installed in the charging module shell. It also includes a first heat exchange tube, a second heat exchange tube and a fin group thermally connected to the charging components. The first heat exchange tube and the second heat exchange tube both include an evaporation section and a condensation section. The evaporation section and condensation section of the first heat exchange tube are thermally connected to the charging components and the inner wall of the charging module shell, respectively. The evaporation section and condensation section of the second heat exchange tube are thermally connected to the outer wall of the charging module shell and the inner wall of the outer box, respectively. However, since the heat source of the charging pile is mainly the heat generated by the charging components, and the heat pipe fin composite heat dissipation type charging pile heat dissipation system only transmits the heat of the charging components through the first heat exchange tube, a large amount of heat remains in the charging components during the heat dissipation process, and the heat dissipation efficiency of the charging components cannot be improved. Utility Model Content

[0004] In view of this, the present invention provides a multi-directional heat dissipation system for charging piles that can improve heat dissipation efficiency to meet industrial needs.

[0005] A multi-directional heat dissipation system for a charging pile, comprising a mounting plate, a charging component arranged on the mounting plate, a first heat dissipation unit arranged on the mounting plate, and a second heat dissipation unit arranged on the mounting plate and abutting one side of the charging component. The first heat dissipation unit comprises a first heat dissipation component arranged on the mounting plate, and at least two first heat dissipation fans respectively arranged at both ends of the first heat dissipation component. The second heat dissipation unit comprises a second heat dissipation component arranged on the mounting plate and abutting one side of the charging component, and at least two second heat dissipation fans respectively arranged at both ends of the heat dissipation component. The first heat dissipation component and the second heat dissipation component have the same structure, and both the first heat dissipation component and the second heat dissipation component comprise a heat dissipation mounting plate, at least one heat-conducting rod arranged on the heat dissipation mounting plate, and a plurality of heat dissipation fins spaced apart on the heat-conducting rod. The heat dissipation mounting plate and the heat conducting rod in the first heat dissipation assembly are both in contact with the mounting plate, the heat dissipation mounting plate and the heat conducting rod in the second heat dissipation assembly are in contact with one side of the charging component, and the heat conducting rod in the first heat dissipation unit and the heat conducting rod in the second heat dissipation unit are perpendicular to each other, so that the heat dissipation fins in the first heat dissipation unit and the heat dissipation fins in the second heat dissipation unit are arranged in a perpendicular direction to each other.

[0006] Furthermore, the first heat dissipation unit and the charging component are spaced apart.

[0007] Furthermore, the multi-directional heat dissipation system for the charging pile also includes a plurality of heat pipes spaced apart on the mounting plate.

[0008] Furthermore, the heat dissipation mounting plate, the heat conducting rod, and the charging components in the first heat dissipation unit are all in contact with the heat pipe.

[0009] Furthermore, the heat sink and the heat conducting rod are vertically connected.

[0010] Furthermore, each heat sink includes a heat sink body, at least one mounting hole arranged on the heat sink body, at least one flange arranged on the edge of the mounting hole, and a plurality of slot-shaped through holes arranged on the edge of the heat sink body.

[0011] Furthermore, the outer contour of the slot-shaped through hole is U-shaped.

[0012] Compared to the prior art, the first heat dissipation unit in the multi-directional heat dissipation system for charging piles provided by the present invention transfers heat from the charging components to the mounting plate for dissipation, while the second heat dissipation unit directly dissipates heat from the charging components. The first and second heat dissipation units have identical structures. Both the first and second heat dissipation assemblies include a heat dissipation mounting plate, at least one heat-conducting rod mounted on the heat-conducting mounting plate, and a plurality of heat sinks spaced apart on the heat-conducting rod. The heat sinks are sequentially mounted on the heat-conducting rods, and the heat-conducting mounting plate and the heat-conducting rods transfer heat to the heat sinks. The heat-conducting rods in the first and second heat dissipation units are perpendicular to each other. It is conceivable that the heat sinks in the first and second heat dissipation units are arranged perpendicularly, so that the air flow in the first and second heat dissipation units is perpendicular to each other, directing airflow in different directions and preventing heat transfer between the first and second heat dissipation units. This demonstrates that the multi-directional heat dissipation system for charging piles forms two heat dissipation channels, dissipating heat in two directions, accelerating cooling and improving heat dissipation efficiency.

[0015] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0016] like Figures 1 to 2 As shown, it is a structural schematic diagram of the multi-directional heat dissipation system for charging piles provided by the present invention. The multi-directional heat dissipation system for charging piles includes a mounting plate 1, a charging component 2 arranged on the mounting plate 1, a first heat dissipation unit 10 arranged on the mounting plate 1, a second heat dissipation unit 20 arranged on the mounting plate 1 and abutting against one side of the charging component 2, and a plurality of heat pipes 30 arranged at intervals on the mounting plate 1. The multi-directional heat dissipation system for charging piles also includes some other functional modules, such as assembly components, etc., which should be technologies well known to those skilled in the art and will not be described in detail here.

[0017] The mounting plate 1 is used to mount the charging component 2, the first heat dissipation unit 10, and the second heat dissipation unit 20. The mounting plate 1 is a metal plate that transfers the heat of the charging component 2 to the first heat dissipation unit 10 and the second heat dissipation unit 20. The mounting plate 1 is an existing technology.

[0018] The charging component 2 is the power supply that provides electricity to the electric vehicle. This charging component system is the core component of the charging station, responsible for converting the electricity from the grid into the specific voltage and current required by the electric vehicle battery. The charging component 2 is a prior art and will not be described in detail here.

[0019] The first heat dissipation unit 10 includes a first heat dissipation assembly 11 disposed on the mounting plate 1, and at least two first heat dissipation fans 12 disposed at both ends of the first heat dissipation assembly 11. The first heat dissipation unit 10 is spaced apart from the charging component 2 and dissipates heat transferred from the charging component 2 to the mounting plate 1 through the mounting plate 1.

[0020] The second heat dissipation unit 20 includes a second heat dissipation component 21 disposed on the mounting plate 1 and abutting against one side of the charging component 2 , and at least two second heat dissipation fans 22 disposed at both ends of the heat dissipation component 21 .

[0021] The first heat dissipation component 21 and the second heat dissipation component 22 have the same structure. Both the first heat dissipation component 11 and the second heat dissipation component 22 include a heat dissipation mounting plate 111, at least one heat conducting rod 112 arranged on the heat dissipation mounting plate 111, and a plurality of heat dissipation fins 113 spaced apart on the heat conducting rod 112.

[0022] Each heat sink 113 includes a heat sink body 1131, at least one mounting hole 1132 provided on the heat sink body 1131, at least one flange 1133 provided on the edge of the mounting hole 1132, and a plurality of slot-shaped through holes 1134 provided on the edge of the heat sink body 1131. The mounting hole 1132 is used to insert the heat conducting rod 112 to achieve the installation between the heat sink 113 and the heat conducting rod 112. The flange 1133 is protruding from one side of the heat sink body 1131, increasing the height of one side of the heat sink body 1131. When multiple heat sinks 113 are stacked together, the heat sinks 113 are spaced apart. The slot-shaped through holes 1134 are used for positioning and installing the heat sinks 113. The outer contour of the slot-shaped through holes 1134 is U-shaped, which increases the edge area of ​​the heat sink body 1131 and improves the heat dissipation efficiency of the heat sink 113.

[0023] During use, multiple heat sinks 113 are sequentially mounted on the heat conducting rod 112, and the heat conducting rod 112 is arranged on the heat dissipation mounting plate 111. The heat dissipation mounting plate 111, the heat conducting rod 112, and the heat sink 113 form a whole. The heat sink 113 is vertically connected to the heat conducting rod 112, that is, the heat sinks 113 are parallel to each other.

[0024] The heat dissipation mounting plate 111 and the heat conducting rod 112 in the first heat dissipation component 11 are both in contact with the mounting plate 1. The first heat dissipation component 11 transfers the heat on the mounting plate 1 to the heat sink 113 in the first heat dissipation component 11 through the heat dissipation mounting plate 111 and the heat conducting rod 112, thereby realizing the heat dissipation of the mounting plate 1 by the first heat dissipation component 11.

[0025] The heat dissipation mounting plate 111 and the heat conducting rod 112 in the second heat dissipation component 22 are in contact with one side of the charging component 2. The second heat dissipation component 22 transfers the heat of the charging component 2 to the heat sink 113 in the second heat dissipation component 22 through the heat dissipation mounting plate 111 and the heat conducting rod 112, thereby realizing the heat dissipation of the charging component 2 by the second heat dissipation component 22.

[0026] Cooling fans are commonly used in electronic devices. They generate airflow to dissipate heat generated by the device, thereby maintaining the device's normal operating temperature. Therefore, the first cooling fan 12 and the second cooling fan 22 are both conventionally used. The two first cooling fans 12 are respectively located at both ends of the first heat dissipation assembly 11, and the two second cooling fans 22 are respectively located at both ends of the second heat dissipation assembly 22. The first heat dissipation assembly 11 and the second heat dissipation assembly 22 are parallel to each other. It is conceivable that the two first cooling fans 12 and the two second cooling fans 22 are located on the same two side edges of the mounting plate 1 to ensure the heat dissipation effect of the first cooling fans 12 and the second cooling fans 22.

[0027] The heat pipe 30 is arranged on the mounting plate 1, and the heat dissipation mounting plate 111, the heat conducting rod 112, and the charging component 2 in the first heat dissipation unit 10 are all in contact with the heat pipe 30, so that the heat pipe 30 can transfer the heat of the charging component 2 to the first heat dissipation unit 10. The heat pipe 30 is an existing technology and will not be described in detail here.

[0028] Compared with the prior art, the first heat dissipation unit 10 in the multi-directional heat dissipation system for charging piles provided by the present invention transfers heat from the charging components 2 to the mounting plate 1 for heat dissipation, and the second heat dissipation unit 20 directly dissipates heat from the charging components 2. The first heat dissipation unit 10 and the second heat dissipation unit 20 have the same structure. The first heat dissipation assembly 11 and the second heat dissipation assembly 22 both include a heat dissipation mounting plate 111, at least one heat-conducting rod 112 disposed on the heat dissipation mounting plate 111, and a plurality of heat dissipation fins 113 spaced apart on the heat-conducting rod 112. The plurality of heat dissipation fins 113 are sequentially sleeved on the heat-conducting rod 112, and the heat dissipation mounting plate 111 and the heat-conducting rod 112 transfer heat to the heat dissipation fins 113. The heat conducting rods 112 in the first heat dissipation unit 10 and the heat conducting rods 112 in the second heat dissipation unit 20 are perpendicular to each other. It is conceivable that the heat dissipation fins 113 in the first heat dissipation unit 10 and the heat dissipation fins 113 in the second heat dissipation unit 20 are arranged perpendicularly to each other, so that the air flow direction in the first heat dissipation unit 10 and the air flow direction in the second heat dissipation unit 20 are mutually perpendicular, guiding the airflow in different directions and avoiding heat transfer between the first heat dissipation unit 10 and the second heat dissipation unit 20. It can be seen from this that the multi-directional heat dissipation system for charging piles forms two heat dissipation channels, dissipating heat in two directions, accelerating the cooling speed and improving heat dissipation efficiency.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
