Description

Technical Field

[0001] The invention relates to the technical field of charging piles, and in particular to a charging pile capable of improving heat dissipation effect. Background Art

[0002] A charging pile refers to a charging device that provides charging services for electric vehicles.

[0003] Charging piles are mainly divided into floor-standing charging piles and wall-mounted charging piles, which mainly adopt the charging methods of time, electricity metering and amount metering. Charging piles can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations, and can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.

[0004] When the charging pile is charging an electric vehicle, its internal electrical components will emit a lot of heat. Most of the existing technologies use air cooling technology to dissipate heat for the charging pile. However, when using air cooling to dissipate heat, the installation position of the cooling fan is fixed and the airflow direction is fixed, resulting in poor heat dissipation effect for electrical components far away from the cooling fan. As the heat dissipation progresses, the temperature near the charging pile increases, the airflow temperature increases, and the heat dissipation effect weakens. Therefore, there is an urgent need for a charging pile that can improve the heat dissipation effect to solve the above problems. Summary of the invention

[0005] The purpose of the embodiments of the present invention is to provide a charging pile that can improve the heat dissipation effect, so as to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In the embodiment of the present invention, please refer to Figures 1 to 5 A charging pile capable of improving heat dissipation effect comprises a charging pile body 1, a heat dissipation hole 3 is provided on the top of the charging pile body 1, an air inlet 9 is provided on the bottom of the charging pile body 1, and further comprises:

[0024] A partition 2 is arranged inside the charging pile body 1 and connected thereto. The partition 2 divides the inside of the charging pile body 1 into two parts. An electrical component is installed on the top of the partition 2. A plurality of through holes are opened on the partition 2.

[0025] A cooling fan 4 is connected to the bottom of the charging pile body 1;

[0026] A second cooling fan 5 is connected to the inner wall of the cooling hole 3;

[0027] The airflow cooling mechanism 6 is connected to the charging pile body 1 and is used to cool the airflow flowing in from the outside. The airflow cooling mechanism 6 includes: a liquid storage tank 61, which is connected to the outer wall of the charging pile body 1, and the liquid storage tank 61 is filled with coolant; a pump 62, which is connected to the outer wall of the liquid storage tank 61, and the input end of the pump 62 is connected to the inside of the liquid storage tank 61; a partition frame 63, which is connected to the inner wall of the charging pile body 1 and is connected to the inside of the pump 62 output end, and the partition frame 63 is located between the partition 2 and the cooling fan 4; a serpentine tube 64, which is arranged inside the partition frame 63, and the top end is connected to the top of the partition frame 63, and the bottom end is connected to the bottom of the partition frame 63, and the serpentine tube 64 is connected to the inside of the charging pile body 1; a liquid outlet pipe 65, one end of which is connected to the top of the partition frame 63; a plugging component 66, one end of which is connected to the inside of the other end of the liquid outlet pipe 65, and the other end is connected to the inside of the liquid storage tank 61;

[0028] The wind direction adjustment mechanism 7 has one end connected to the output end of the cooling fan 2 5 and the other end connected to the charging pile body 1 for adjusting the outflow angle of the airflow.

[0029] When the charging pile body 1 charges the new energy vehicle, the internal electrical components will emit a lot of heat, and the cooling fan 1 4 and the cooling fan 2 5 will work. The cooling fan 1 4 accelerates the rate at which the external cold airflow enters the charging pile body 1, and the cooling fan 2 5 accelerates the rate at which the hot airflow inside the charging pile body 1 flows out, thereby dissipating the heat of the charging pile body 1. The external airflow enters the bottom of the charging pile body 1, and then enters the top of the charging pile body 1 through the serpentine tube 64, the wind direction adjustment mechanism 7 and the partition 2. When the airflow passes through the serpentine tube 64, the coolant inside the partition frame 63 cools the airflow, and the serpentine tube 64 increases the flow distance and residence time of the airflow inside the partition frame 63, further improving the cooling effect of the airflow. The wind direction adjustment mechanism 7 adjusts the flow direction of the cooled airflow to ensure that the airflow can flow through every corner inside the charging pile body 1, thereby ensuring the heat dissipation effect;

[0030] In the initial state, the blocking component 66 is in a blocked state, the pump 62 is in a stopped state, the coolant inside the bulkhead 63 does not flow into the liquid storage tank 61, and the coolant fills the bulkhead 63;

[0031] After the external air flow enters the serpentine tube 64, the coolant exchanges heat with the external air flow to cool the external air flow, causing the temperature of the coolant in the bulkhead 63 to rise. As the temperature of the coolant rises, its cooling effect becomes worse. When the temperature of the coolant in the bulkhead 63 rises to a certain level, the plugging component 66 is opened, and the pump 62 works at the same time to transport the coolant in the liquid storage tank 61 to the bulkhead 63. The coolant in the bulkhead 63 returns to the liquid storage tank 61 through the plugging component 66 for heat dissipation. When the coolant in the bulkhead 63 is completely replaced by the coolant in the liquid storage tank 61, the plugging component 66 is closed and the pump 62 stops working to ensure the cooling effect on the external air flow. At the same time, the setting of the plugging component 66 divides the coolant into two parts, so that the cooling efficiency of the coolant in the liquid storage tank 61 is fast, while saving electricity resources.

[0032] In this embodiment, the cooling fan 1 4 and the cooling fan 2 5 are both a combination structure of a drive motor and fan blades. The fan blades are connected to the output end of the drive motor. The drive motor drives the fan blades to rotate, thereby driving the airflow and increasing the airflow speed.

[0033] In this embodiment, the interior of the liquid storage tank 61 may be connected to a coolant radiator, and the coolant radiator dissipates the heat of the coolant in the liquid storage tank 61 to ensure the cooling effect of the coolant.

[0034] As an embodiment of the present invention, please refer to Figures 1 to 4 , the blocking component 66 comprises:

[0035] A connecting cylinder 661, the bottom end of which is connected to the liquid storage tank 61 and communicates with the interior thereof;

[0036] The cavity tube 662 is connected to the top of the connecting tube 661. The cavity tube 662 is divided into two chambers, an inner chamber and an outer chamber, and the two chambers are not connected.

[0037] The connecting tube 663 has a top end connected to the top of the cavity tube 662 and communicated with the interior of the outer cavity, and a bottom end connected to the top of the connecting tube 661;

[0038] The sliding rod 664 penetrates through the cavity 662 and the connecting tube 661 and is slidably connected thereto;

[0039] The annular cone block 665 is connected to the inner wall of the connecting tube 661. The annular cone block 665 is annular and has a beveled edge structure at the bottom.

[0040] The cone blocking block 666 is connected to the bottom end of the sliding rod 664, and the top of the cone blocking block 666 is cylindrical and the bottom is truncated cone;

[0041] The power assembly 667 has one end connected to the sliding rod 664 and the other end connected to the cavity 662, and is used to drive the sliding rod 664 to move longitudinally.

[0042] In the initial state, the blocking cone block 666 abuts against the ring cone block 665, and the cooling liquid fills the outer chamber of the cavity 662;

[0043] As the temperature of the coolant inside the partition frame 63 and the outer chamber increases, the power component 667 drives the sliding rod 664 to move downward, and the sliding rod 664 drives the blocking cone block 666 to move downward. Since the top of the blocking cone block 666 is cylindrical, the blocking cone block 666 still cooperates with the annular cone block 665 to block the coolant for a period of time at the beginning, and the coolant cannot enter the interior of the liquid storage tank 61. When the temperature of the coolant rises to a certain temperature, the blocking cone block 666 is separated from the annular cone block 665. At this time, the top and bottom of the connecting tube 661 are connected, and the coolant can enter the interior of the liquid storage tank 61 through the connecting pipe 663 and the connecting tube 661. When the coolant is replaced, the power component 667 drives the sliding rod 664 to move upward, and the blocking cone block 666 cooperates with the annular cone block 665 to re-block.

[0044] As an embodiment of the present invention, please refer to Figures 1 to 4 , the power assembly 667 includes:

[0045] The piston block 6671 is disposed in the inner chamber and is slidably connected to the chamber tube 662. The piston block 6671 is connected to the sliding rod 664. A heat expansion agent is installed between the piston block 6671 and the top space of the inner chamber.

[0046] The air pipe 6672 is connected to the bottom of the cavity 662 and communicates with the interior of the inner chamber;

[0047] The elastic member 6673 is disposed inside the inner chamber, and the top end is connected to the top of the chamber 662, and the bottom end is connected to the piston block 6671;

[0048] Magnet 1 6674 is connected to the top outer wall of the cavity 662;

[0049] Magnet 2 6675 is connected to the top of the sliding rod 664 and has opposite magnetic properties to magnet 1 6674 .

[0050] The heated expansion agent expands when heated, squeezing the piston block 6671 to move downward, the piston block 6671 drives the sliding rod 664 to move downward, and the elastic member 1 6673 undergoes elastic deformation at the same time, and the sliding rod 664 drives the blocking cone block 666 and the second magnet 6675 to move downward synchronously. When the blocking cone block 666 is separated from the ring cone block 665, the second magnet 6675 contacts the first magnet 6674 and is magnetically adsorbed together, and the elastic member 1 6673 reaches the maximum expansion and contraction amount. In this embodiment, the adsorption force between the second magnet 6675 and the first magnet 6674 is slightly smaller than the maximum resilience of the elastic member 1 6673. During the replacement of the coolant, due to the thermal expansion of the heated expansion agent, The expansion generates a squeezing force, and the combined force of the two is greater than the maximum resilience of the elastic part 1 6673, so that the sliding rod 664 remains stationary. When the coolant is replaced, the volume of the heated expansion agent shrinks to the original state, and the squeezing force disappears. Since the adsorption force between the second magnet 6675 and the first magnet 6674 is slightly smaller than the maximum resilience of the elastic part 1 6673, at this time, under the reaction force of the elastic part 1 6673, the second magnet 6675 is separated from the first magnet 6674, and the sliding rod 664 moves upward, driving the cone block 666 to move upward, and re-blocking the center of the ring cone block 665. The elastic part 1 6673 can be a spring, a spring sheet, etc.

[0051] In this embodiment, the heat expansion agent can be an item that expands in volume when heated and contracts in volume when cooled, and has good expansion and contraction effects, such as hydrogen, helium, etc.

[0052] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 5 , the wind direction adjustment mechanism 7 comprises:

[0053] The adjusting plate 71 is disposed between the partition plate 2 and the partition frame 63 and is rotatably connected to the charging pile body 1. The adjusting plate 71 is provided in several groups;

[0054] Gear 1 72, connected to the adjustment plate 71;

[0055] The tooth plate 73 is slidably connected to the charging pile body 1 and meshes with the gear 1 72;

[0056] The reciprocating assembly 74 has one end connected to the output end of the cooling fan 2 5 and the other end connected to the tooth plate 73, and is used to drive the tooth plate 73 to reciprocate laterally.

[0057] When the cooling fan 2 5 is working, it drives the reciprocating component 74 to move, the reciprocating component 74 drives the tooth plate 73 to reciprocate horizontally, the tooth plate 73 drives the gear 1 72 to rotate alternately clockwise and counterclockwise, and the gear 1 72 drives the adjustment plate 71 to rotate alternately clockwise and counterclockwise. When the airflow passes through the adjustment plate 71, the angle of the adjustment plate 71 changes continuously, causing the flow direction of the airflow to change, thereby ensuring that the airflow can flow through every corner of the charging pile body 1 to ensure the heat dissipation effect.

[0058] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 5 , the reciprocating assembly 74 comprises:

[0059] The toothless ring 741 is connected to the output end of the second cooling fan 5, and gear teeth are provided at a part of the upper portion of the toothless ring 741;

[0060] Gear 2 742 meshes with the gear teeth on the toothless ring 741;

[0061] The winding rod 743 is connected to the second gear 742 and is rotationally connected to the heat dissipation hole 3;

[0062] The connecting rope 744 passes through the bottom of the heat dissipation hole 3 and one side of the charging pile body 1, and one end is connected to the winding rod 743, and the other end is connected to the gear plate 73;

[0063] The limiting roller 746 is connected to the outer wall of the charging pile body 1 and abuts against the connecting rope 744, and is used to limit the connecting rope 744 and ensure smooth movement of the connecting rope 744;

[0064] The second elastic member 745 has one end connected to the tooth plate 73 and the other end connected to the inner wall of the charging pile body 1 .

[0065] When the cooling fan 25 is working, the toothless ring 741 is driven to rotate. When the gear teeth on the toothless ring 741 mesh with the gear 2 742, the toothless ring 741 drives the gear 2 742 to rotate. The gear 2 742 drives the winding rod 743 to rotate. The winding rod 743 winds the connecting rope 744, thereby driving the tooth plate 73 to move to one side. At the same time, the elastic member 2 745 is elastically deformed. When the toothless ring 741 rotates to not mesh with the gear 2 742, the gear plate 73 moves in the opposite direction under the reaction force of the elastic member 2 745. The elastic member 2 745 can be a spring, a spring sheet, etc.

[0066] As an embodiment of the present invention, filter screens are provided in the air inlet 9 and the heat dissipation holes 3 .

[0067] The filter screen is provided to prevent external dust from entering the interior of the charging pile body 1 through the air inlet 9 and the heat dissipation holes 3 to affect the service life of the electrical components inside the charging pile body 1.

[0068] As an embodiment of the present invention, please refer to Figure 2 and Figure 6 , further comprising: a knocking mechanism 8, arranged at the bottom of the partition 2, for knocking the filter screen inside the air inlet 9, the knocking mechanism 8 comprising:

[0069] A limiting rod 81, one end of which is slidably connected to the inner wall of the charging pile body 1;

[0070] The folding rod 82 is connected to the other end of the limiting rod 81;

[0071] The elastic member 3 83 has a top end connected to the limit rod 81 and a bottom end connected to the bottom of the charging pile body 1;

[0072] A hemispherical body 84 connected to the top of the folding rod 82;

[0073] A fixing rod 85 is connected to the output end of the cooling fan 4, and the highest point of the fixing rod 85 is slightly lower than the center of the hemisphere 84;

[0074] The knocking block 86 is connected to the bottom end of the folding rod 82.

[0075] The knocking block 86 abuts against the top of the filter screen inside the air inlet 9. When the heat dissipation fan 1 4 is working, it drives the fixed rod 85 to rotate. Since the highest point of the fixed rod 85 is slightly lower than the center of the hemisphere 84, the fixed rod 85 will hit the hemisphere 84, causing the hemisphere 84 to move upward under the extrusion force of the fixed rod 85. The hemisphere 84 drives the folding rod 82 to move upward, and the folding rod 82 drives the knocking block 86 to move upward. At the same time, the elastic member 3 83 undergoes elastic deformation. When the fixed rod 85 is separated from the hemisphere 84, the knocking block 86 moves downward under the reaction force of the elastic member 3 83, knocking the filter screen, causing the filter screen to vibrate, preventing dust from clogging the filter screen inside the air inlet 9, and ensuring that the outside air can enter the charging pile body 1 through the air inlet 9. The elastic member 3 83 can be a spring, a shrapnel, etc.

[0076] The working principle of the present invention is as follows: in the initial state, the blocking cone block 666 abuts against the ring cone block 665, the pump 62 is in a shutdown state, and the coolant fills the outer chamber of the bulkhead 63 and the cavity 662;

[0077] When the charging pile body 1 charges the new energy vehicle, the internal electrical components will emit a lot of heat, and the cooling fan 1 4 and the cooling fan 2 5 will work. The cooling fan 1 4 accelerates the speed of the external cold airflow entering the charging pile body 1, and the cooling fan 2 5 accelerates the speed of the hot airflow out of the charging pile body 1, so as to dissipate the heat of the charging pile body 1. The external airflow enters the bottom of the charging pile body 1, and then enters the top of the charging pile body 1 through the serpentine tube 64, the wind direction adjustment mechanism 7 and the partition 2. When the airflow passes through the serpentine tube 64, the coolant inside the partition frame 63 cools the airflow, and the serpentine tube 64 increases the flow distance and residence time of the airflow inside the partition frame 63, further improving the cooling effect of the airflow. When the cooling fan 2 5 is working, it drives the toothed ring 741 to rotate. When the gear teeth on the toothed ring 741 are aligned with the gear 2 7 When the toothed ring 741 is in meshing with the gear 2 742, the gear 2 742 drives the winding rod 743 to rotate, and the winding rod 743 winds the connecting rope 744, thereby driving the tooth plate 73 to move to one side. At the same time, the elastic member 2 745 undergoes elastic deformation. When the toothed ring 741 rotates to no longer mesh with the gear 2 742, the tooth plate 73 moves in the opposite direction under the reaction force of the elastic member 2 745. The tooth plate 73 reciprocates laterally, driving the gear 1 72 to rotate alternately clockwise and counterclockwise, and the gear 1 72 drives the adjusting plate 71 to rotate alternately clockwise and counterclockwise. When the airflow passes through the adjusting plate 71, the angle of the adjusting plate 71 changes continuously, resulting in a change in the flow direction of the airflow, thereby ensuring that the airflow can flow through every corner of the charging pile body 1 and ensuring the heat dissipation effect.

[0078] After the outside airflow enters the inside of the serpentine tube 64, the coolant exchanges heat with the outside airflow to cool the outside airflow, so that the temperature of the coolant inside the bulkhead 63 and the outer chamber increases, and the heated expansion agent expands due to the heat, squeezing the piston block 6671 to move downward, and the piston block 6671 drives the sliding rod 664 to move downward. The elastic part 1 6673 undergoes elastic deformation at the same time, and the sliding rod 664 drives the blocking cone block 666 and the magnet 2 6675 to move downward synchronously. When the blocking cone block 666 is separated from the annular cone block 665, the magnet 2 6675 contacts the magnet 1 6674 and is magnetically adsorbed together. The expansion and contraction amount of the elastic part 1 6673 reaches the maximum, and the adsorption force between the magnet 2 6675 and the magnet 1 6674 is slightly smaller than the maximum resilience of the elastic part 1 6673. At this time, the blocking cone block 666 is separated from the annular cone block 665, and the pump 62 works at the same time to cool the coolant inside the liquid storage tank 61. It is transported to the interior of the bulkhead 63, and the coolant inside the bulkhead 63 returns to the interior of the liquid storage tank 61 through the connecting pipe 663 and the connecting cylinder 661 for heat dissipation. During the replacement of the coolant, the heat expansion agent generates an extrusion force due to the heat expansion, and the combined force of the two is greater than the maximum resilience of the elastic part 1 6673, so that the sliding rod 664 remains stationary. When the coolant is replaced, the volume of the heat expansion agent shrinks to its original state, and the extrusion force disappears. Since the adsorption force between the magnet 2 6675 and the magnet 1 6674 is slightly smaller than the maximum resilience of the elastic part 1 6673, at this time, under the reaction force of the elastic part 1 6673, the magnet 2 6675 is separated from the magnet 1 6674, and the sliding rod 664 moves upward, driving the blocking cone block 666 to move upward, and re-blocking the center part of the annular cone block 665.
