Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a heat dissipation device for a new energy vehicle charging pile. Background Art

[0002] A charging pile, also known as a new energy electric vehicle charging station or a new energy electric vehicle power supply equipment, is a device that provides electrical energy to new energy electric vehicles, enabling new energy electric vehicles to store enough electricity to support their operation.

[0003] During the charging process, the electrical equipment inside the charging pile will convert and transmit current, which will generate a certain amount of heat, such as electronic components such as power conversion modules. Especially for DC charging piles, due to their fast charging characteristics, the current is large, so the heat generated will also increase accordingly. If the heat dissipation system of the charging pile is not perfect or it runs at high load for a long time, it may cause heat accumulation, which will cause safety hazards.

[0004] In the prior art, a cooling fan is usually installed inside or outside the charging pile, and the electronic components dissipate heat into the air inside the charging pile. The rotation of the fan generates airflow, which takes away the hot air inside the charging pile and discharges it into the external environment, promoting the heat dissipation inside the charging pile and reducing the risk of fire caused by heat accumulation inside the charging pile. However, most charging piles are installed in outdoor environments, and dust in the outdoor environment can easily enter the charging pile through the vents on the charging pile shell. After the dust settles, it adheres to the surface of the electronic components, reducing the heat dissipation capacity of the electronic components. Summary of the invention

[0015] Furthermore, the end surface of the rotating block facing one end of the heat dissipation block covers the opening of the slide slot to form a closed chamber, and the push bar and the slide slot are slidably and sealedly matched;

[0016] The side of the push strip facing away from the compression spring is provided with a heat absorbing expansion material.

[0017] Furthermore, both facing side surfaces of the first heat sink and the corresponding second heat sink intersect with the axis of the heat sink block.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0040] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0041] See also Figure 1-9The present invention provides a technical solution: a heat dissipation device for a new energy vehicle charging pile, comprising a heat pipe 1 for transferring heat from electronic components to the outside of a charging cabinet and a heat dissipation block 2 for dissipating heat from the heat pipe 1, wherein a portion of the heat pipe 1 is disposed inside the charging pile and in contact with the electronic components, and another portion is disposed outside the charging pile;

[0042] The heat sink block 2 is arranged outside the charging pile, and is sleeved outside the heat pipe 1 and fixedly connected.

[0043] By embedding a portion of the heat pipe 1 into the charging pile and contacting with the electronic components, the heat generated by the electronic components is transferred to the heat pipe 1, and the heat is transported to the outside of the charging pile through the heat pipe 1, and the heat on the heat pipe 1 is dissipated to the air outside the charging pile through the heat dissipation block 2, so as to achieve the purpose of heat dissipation of the charging pile. Most of the heat generated by the electronic components is directly transmitted to the outside of the charging cabinet through the heat pipe 1, and a small amount of heat is released into the air inside the charging cabinet, reducing the risk of fire caused by excessive temperature in the charging cabinet. Therefore, there is no need to use a cooling fan to promote air circulation on both sides of the charging cabinet, thereby reducing the number of vents and reducing the impact of dust on the heat dissipation of electronic components.

[0044] In this embodiment: the heat sink 2 is cylindrical and has a plurality of first heat sinks 21 on its outer surface, and the plurality of first heat sinks 21 are evenly distributed around the circumference of the heat sink 2;

[0045] The first heat sink 21 is parallel to the axis of the heat sink block 2 , and one side is fixedly connected to the outer circumferential surface of the heat sink block 2 , while the other side extends away from the heat sink block 2 .

[0046] By setting the first heat sink 21 on the outer surface of the heat sink block 2, the contact area between the heat sink block 2 and the air is increased, the heat loss in the heat sink block 2 is promoted, and the heat dissipation efficiency is improved. At the same time, a heat dissipation fan can be installed on the charging pile shell, and the fan blades of the heat dissipation fan are rotated to accelerate the air flow around the heat sink block 2, so as to promote the hot air around the heat sink block 2 to move to the surroundings, accelerate the diffusion of heat, and improve the heat dissipation efficiency of the heat sink 2.

[0047] In this embodiment: a rotating block 3 is disposed on one end of the heat dissipation block 2 and rotatably cooperates with it. Second heat dissipation fins 31 corresponding to the plurality of first heat dissipation fins 21 are fixedly connected to the outer circumferential surface of the rotating block 3 .

[0048] The heat pipe 1, the heat sink block 2, the first heat sink 21, the rotating block 3 and the second heat sink 31 are all made of copper. Copper has good thermal conductivity and can effectively conduct away the heat generated by electronic components.

[0049] By arranging a rotating block 3 on the heat dissipation block 2 and rotating the rotating block 3 with the heat dissipation block 2, the spacing between the second heat dissipation fins 31 and the first heat dissipation fins 21 can be adjusted, and the second heat dissipation fins 31 can drive the rotating block 3 to rotate on the heat dissipation block 2 when natural wind or artificial wind blows, so that the second heat dissipation block 2 and the first heat dissipation block 2 collide with each other and shake, thereby promoting the dust that settles and adheres to the heat dissipation block 2 or the rotating block 3 to fall off, and reducing the influence of dust on the heat dissipation of the heat dissipation block 2 and the rotating block 3. At the same time, when the second heat dissipation block 2 and the first heat dissipation block 2 move relative to each other, it can promote the circulation of hot air in the gap between the two and the surrounding air, thereby further improving the heat dissipation efficiency.

[0050] In this embodiment: a slide groove 22 is provided on the end surface of the heat dissipation block 2 facing the rotating block 3, and the slide groove 22 extends in the circumferential direction of the heat dissipation block 2;

[0051] A push bar 32 is slidably fitted in the slide slot 22, and one end of the push bar 32 protrudes from the opening of the slide slot 22 and is fixedly connected to the rotating block 3;

[0052] A compression spring 33 is provided on one side of the push bar 32, one end of the compression spring 33 is fixedly connected to the push bar 32, and the other end is fixedly connected to the side wall of the slide slot 22, and when the compression spring 33 is in a naturally extended state, the second heat sink 31 abuts against the corresponding first heat sink 21.

[0053] In this embodiment: the end surface of the rotating block 3 facing the heat dissipation block 2 covers the opening of the slide groove 22 to form a closed chamber, and the push bar 32 slides and seals with the slide groove 22;

[0054] The push bar 32 is provided with a heat-absorbing expansion material 34 on the side facing away from the compression spring 33 .

[0055] By opening a slide groove 22 on the heat dissipation block 2 and covering the opening of the slide groove 22 with the rotating block 3, a closed chamber is formed in the slide groove 22, and a push bar 32 is arranged on the rotating block 3, and the push bar 32 is embedded in the slide groove 22 and slidably and sealed, so that the push bar 32 is similar to a piston in a piston cylinder structure. When the heat dissipation block 2 absorbs heat and the temperature rises, the temperature in the sealed chamber rises, and the heat-absorbing expansion material 34 absorbs heat and expands, pushing the push bar 32 to slide in the sealed chamber in the slide groove 22, and the compression spring 33 is squeezed and contracted. At the same time, the push bar 32 drives the rotating block 3 to rotate on the heat dissipation block 2, so that the second heat sink 31 and the corresponding first heat sink 21 move relative to each other, thereby increasing the gap size between the two, promoting air flow, and improving heat dissipation efficiency.

[0056] When the charging pile stops charging, the heat generated by the internal electronic components decreases, which reduces the temperature of the heat pipe 1. As the heat is continuously dissipated, the temperature of the heat dissipation block 2 and the rotating block 3 continues to decrease, which reduces the volume of heat loss in the heat-absorbing expansion material 34 and the thrust on the push bar 32. The compression spring 33 releases energy to push the push bar 32 to slide in the opposite direction until it returns to the initial position, causing the second heat sink 31 to collide and vibrate with the first heat sink 21, thereby promoting the shedding of dust.

[0057] Among them, the heat-absorbing expansion material 34 can be water or alcohol. Water or alcohol is liquid at room temperature and has a small volume. Water or alcohol will vaporize into a gas when absorbing heat. As the temperature on the heat sink 2 continues to rise, the amount of vaporized water or alcohol increases, causing the pressure in the sealed chamber facing away from the compression spring 33 to continue to increase, so as to push the push bar 32 to slide, gradually increase the gap size between the first heat sink 21 and the second heat sink 31, and promote heat dissipation.

[0058] In this embodiment: both facing side surfaces of the first heat sink 21 and the corresponding second heat sink 31 intersect with the axis of the heat sink block 2 .

[0059] By arranging the two facing side surfaces of the first heat sink 21 and the corresponding second heat sink 31 to intersect with the axis of the heat sink 2, when the second heat sink 31 and the corresponding second heat sink 31 are abutted against each other, the two relative side surfaces fit together, so that the second heat sink 31 and the first heat sink 21 are spliced ​​to form a thicker heat sink, thereby reducing the probability of the first heat sink 21 and the second heat sink 31 being damaged by bumps.

[0060] That is, when the charging pile is not charging, the first heat sink 21 and the second heat sink 31 overlap, and the two facing sides of the first heat sink 21 and the second heat sink 31 are covered, reducing the probability of the first heat sink 21 and the second heat sink 31 being damaged by collision. When the charging pile is charging, the two facing sides of the first heat sink 21 and the second heat sink 31 are exposed and open, increasing the contact area with the air and promoting heat dissipation.

[0061] In this embodiment, the first heat sink 21 and the second heat sink 31 are both in the shape of a triangular prism, and the thickness of the side facing away from the heat sink block 2 is smaller than the thickness of the side close to the heat sink block 2 .

[0062] The first heat sink 21 and the second heat sink 31 are arranged in a triangular prism configuration to optimize the heat conduction path. During the heat dissipation process of the first heat sink 21, the heat starts from the heat sink block 2 and is transferred along the gradually tapering path of the first heat sink 21 to a side away from the heat sink block 2, which helps to reduce the accumulation and retention of heat inside the first heat sink 21, thereby accelerating the heat transfer speed.

[0063] In this embodiment: the heat conducting pipe 1 is filled with a heat absorbing medium, and the heat absorbing medium can flow in the heat conducting pipe 1;

[0064] A delivery pump 4 is disposed on the heat conduction pipe 1 , one end of the heat conduction pipe 1 is communicated with the input end of the delivery pump 4 , and the other end of the heat conduction pipe 1 is fixedly connected and communicated with the output end of the delivery pump 4 .

[0065] The heat absorbing medium filled in the heat pipe 1 is water, which has a high specific heat capacity and good fluidity. By filling water in the heat pipe 1, after the heat pipe 1 absorbs the heat generated by the electronic components, the heat can quickly enter the water, and the heat pipe 1 and the delivery pump 4 are spliced ​​to form a closed-loop water delivery pipeline. Under the action of the delivery pump 4, water circulates in the heat pipe 1 in one direction to push the hot water after absorbing the heat to move to the outside of the charging pile. When it moves to the heat dissipation block 2, due to the temperature difference between the heat dissipation block 2 and the hot water in the heat pipe 1, the heat in the hot water is transferred to the heat dissipation block 2. The heat dissipation block 2 dissipates the heat into the air through the first heat sink 21 and the second heat sink 31 on the rotating block 3, so that the temperature of the hot water is reduced and cooled. The cooled water is again transported into the charging cabinet by the delivery pump 4 to transport heat again, so that the device continues to perform heat dissipation.

[0066] In this embodiment: a storage tank 5 for storing heat-absorbing medium is provided on one side of the delivery pump 4, the input end of the delivery pump 4 is fixedly connected and communicated with the bottom end of the side wall of the storage tank 5, and the end of the heat-conducting pipe 1 facing away from the delivery pump 4 is fixedly connected and communicated with the bottom end of the side wall of the storage tank 5.

[0067] By setting up a storage tank 5 and storing a certain amount of water in the storage tank 5, when the water that has absorbed part of the heat through the heat dissipation block 2 enters the storage tank 5, it mixes with the water stored in the storage tank 5, and dissipates heat through the outer wall of the storage tank 5 in contact with the air, thereby lowering the water temperature again.

[0068] In this embodiment: a through hole 51 is opened at the top of the storage tank 5 to connect the inside and outside of the storage tank 5 , and a sealing disk 52 is slidably and sealingly matched inside the storage tank 5 .

[0069] By opening a through hole 51 at the top of the storage tank 5 and covering the through hole 51 with a sealing disk 52, the interior of the heat pipe 1 is kept sealed. Since the sealing disk 52 slides with the storage tank 5, the overall internal volume of the water pipeline formed by the heat pipe 1, the delivery pump 4 and the storage tank 5 can be changed, so as to balance the pressure on both sides of the water pipeline and reduce the risk of bursting due to excessive pressure in the water pipeline.

[0070] Among them, the specific model of the delivery pump 4 is Chuangsheng Pump Industry TDM-200ERU-DC48.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
