[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0029] Figure 1 This diagram shows a front view of the integrated DC pile in an embodiment of the present invention. Figure 2 A schematic diagram of the rear structure of the DC integrated pile in an embodiment of this utility model is shown. This utility model provides a DC integrated pile, including a cabinet 1, a cabinet door 10 on the front of the cabinet 1, a U-shaped rear cover 20 on the back of the cabinet 1, and a bottom rear cover 30 at the bottom of the back of the cabinet 1.
[0030] Figure 3 This diagram shows a first exploded structural schematic of the DC integrated pile in an embodiment of the present invention. Figure 4 This diagram shows a second exploded view of the integrated DC pile in an embodiment of the present invention. Figure 5 A schematic diagram of the internal structure of the back of the DC integrated pile in an embodiment of this utility model is shown.
[0031] The front of the cabinet 1 has a first accommodating space 100, and the back of the cabinet 1 has a second accommodating space 200. The first accommodating space 100 and the second accommodating space 200 are separated by a wall panel 40. The first accommodating space 100 is equipped with control circuits and protection circuits, and the second accommodating space 200 is equipped with high-power devices. One side of the cabinet 1 has a cabinet air inlet 210, and the other side of the cabinet 1 has a cabinet air outlet 220. Both the cabinet air inlet 210 and the cabinet air outlet 220 are connected to the second accommodating space 200. A partition 50 is provided inside the second accommodating space 200, and the cabinet air inlet 210 and... An air inlet space 201 is formed between the partition plates 50, and an air outlet space 202 is formed between the cabinet air outlet 220 and the partition plates 50; a plurality of ventilation holes 41 are provided on the wall panel 40, and the first accommodating space 100 and the air outlet space 202 are connected through the plurality of ventilation holes 41; a plurality of air duct boxes 60 are installed in the second accommodating space 200, the high-power device is located in the air duct box 60, an intake fan 61 is provided at one end of the air duct box 60, and an exhaust fan 62 is provided at the other end of the air duct box 60; the intake fan 61 is located in the air inlet space 201, and the exhaust fan 62 is located in the air outlet space 202.
[0032] In the DC integrated pile of this utility model, the intake fan 61 draws air from the intake space 201 and delivers it into the air duct box 60, and the exhaust fan 62 draws air from the air duct box 60 and delivers it into the exhaust space 202, thereby forming a strong airflow in the air duct box 60, which can effectively help the high-power devices in the air duct box 60 dissipate heat.
[0033] When the intake fan 61 draws air from the intake space 201 and delivers it into the air duct box 60, it creates a negative pressure in the intake space 201, causing outside air to automatically replenish the intake space 201 from the rack air inlet 210. When the exhaust fan 62 draws air from the air duct box 60 and delivers it into the exhaust space 202, the exhaust fan 62 outputs an airflow that is ejected from the rack air outlet 220. According to Bernoulli's principle, the pressure in the exhaust space 202 will decrease, causing the air in the first receiving space 100 to automatically replenish the exhaust space 202 through the ventilation hole 41. That is, the air in the first receiving space 100 starts to circulate, which is beneficial for the heat dissipation of the control circuit and protection circuit in the first receiving space 100.
[0034] In some specific embodiments, please refer to Figure 5 The volume ratio of the air intake space 201 to the air outlet space 202 is 1:2 to 3. On the one hand, the volume of the air intake space 201 is smaller, which is conducive to enhancing the air intake capacity of the air intake space 201; on the other hand, the volume of the air outlet space 202 is larger, and its connectivity with the first receiving space 100 is good, which facilitates the movement of air from the first receiving space 100.
[0035] In some specific embodiments, please refer to Figure 4 and Figure 5 A filter screen 70 is provided between the air intake fan 61 and the air inlet 210 of the cabinet, which can prevent dust from being sucked into the air duct box 60 and help protect the high-power components inside the air duct box 60.
[0036] In some specific embodiments, please refer to Figure 3 and Figure 5 The exhaust fan 62 is directly opposite the air outlet 220 of the cabinet, and the distance between the exhaust fan 62 and the air outlet 220 of the cabinet is at least 5cm, so that the airflow output by the exhaust fan 62 has sufficient travel in the air outlet space 202, and can effectively form a low-pressure area in the air outlet space 202, thereby facilitating the automatic replenishment of the air in the first accommodating space 100 into the air outlet space 202 through the ventilation hole 41.
[0037] In some specific embodiments, the intake fan 61 and the exhaust fan 62 have the same power, which is beneficial to forming a good stream of airflow in the air duct box 60, resulting in good heat dissipation for high-power devices.
[0038] In some specific embodiments, please refer to Figure 3 and Figure 5 The bottom of the cabinet 1 is provided with a third accommodating space 300, which is connected to the first accommodating space 100 through a cable hole 310, so as to facilitate the introduction of the power supply cable from the third accommodating space 300 into the first accommodating space 100.
[0039] For details, please refer to Figure 5 A carbon dioxide storage tank 320 is installed in the third containment space 300. The carbon dioxide storage tank 320 is connected to the first containment space 100 through a first release pipe, and to the air intake space 201 through a second release pipe. If an uncontrollable abnormal high temperature occurs inside the DC integrated pile, the carbon dioxide storage tank 320 will be automatically activated to release low-temperature carbon dioxide gas into the first containment space 100 and the air intake space 201. This not only cools the internal components but also inhibits the combustion of the internal components.
[0040] In some specific embodiments, please refer to Figure 5 A refrigeration device 330 is installed in the third accommodating space 300. The air inlet of the refrigeration device 330 is connected to the air intake space 201 through an air intake pipe. The cooling outlet of the refrigeration device 330 is connected to the air intake space 201 through a cooling outlet pipe 331. The heat release outlet of the refrigeration device 330 is connected to the air outlet space 202 through a heat release pipe. The refrigeration device 330 is existing, and its core is a semiconductor cooler. When the outside temperature is relatively high, it is difficult to effectively cool the high-power devices in the air duct box 60 by relying solely on the intake fan 61 and the exhaust fan 62. At this time, the refrigeration device 330 can be activated to release cold air into the air intake space 201 to improve the cooling effect on the high-power devices in the air duct box 60.
[0041] For details, please refer to Figure 5 The cooling pipe 331 runs through the entire second accommodating space 200 from bottom to top. Multiple cooling holes are provided on the cooling pipe 331, which helps to distribute the cold air to the entire air intake space 201 and ensure the cooling effect of all high-power devices in the air duct box 60.
[0042] In some specific embodiments, please refer to Figure 5 A smoke generator 340 is installed in the third accommodating space 300. The release port of the smoke generator 340 is connected to the air outlet space 202 through a smoke release pipe. If an uncontrollable abnormal high temperature occurs inside the DC integrated pile, the smoke generator 340 will be automatically activated, releasing red, yellow, or blue smoke (not white, black, or gray). The smoke will drift out from the air outlet 220 of the cabinet, which is extremely conspicuous and can effectively attract external attention, thus serving as a warning.
[0043] In some specific embodiments, please refer to Figure 5 The plurality of air duct boxes 60 are arranged vertically within the second accommodating space 200, and there is a ventilation gap between two adjacent air duct boxes 60. The ventilation gap exposes the ventilation hole 41, which helps to ensure the connection between the first accommodating space 100 and the air outlet space 202.
[0044] The working principle of this utility model's integrated DC pile is as follows:
[0045] The intake fan 61 draws air from the intake space 201 and delivers it into the air duct box 60, while the exhaust fan 62 draws air from the air duct box 60 and delivers it into the exhaust space 202, thereby creating a strong airflow within the air duct box 60, which can effectively help dissipate heat from high-power components within the air duct box 60.
[0046] When the intake fan 61 draws air from the intake space 201 and delivers it into the air duct box 60, it will create a negative pressure in the intake space 201, so that the outside air will be automatically replenished into the intake space 201 from the cabinet air inlet 210.
[0047] When the exhaust fan 62 draws air from the air duct box 60 and delivers it to the exhaust space 202, the exhaust fan 62 outputs an airflow that is ejected from the cabinet exhaust port 220. According to Bernoulli's principle, the pressure in the exhaust space 202 will decrease, causing the air in the first receiving space 100 to automatically flow into the exhaust space 202 through the ventilation hole 41. That is, the air in the first receiving space 100 starts to circulate, which is beneficial to the heat dissipation of the control circuit and protection circuit in the first receiving space 100.
[0048] In this DC integrated charging pile, by installing the control circuit and protection circuit in the first accommodating space 100, and installing the high-power devices in the air duct box 60 of the second accommodating space 200, and connecting the first accommodating space 100 and the air outlet space 202, the heat dissipation effect inside the DC integrated charging pile can be effectively improved, thereby ensuring the charging efficiency of the DC integrated charging pile. Moreover, a filter screen 70 is provided in the air inlet space 201 to prevent dust from being sucked into the air duct box 60, which is beneficial to protecting the high-power devices inside the air duct box 60. In addition, a third accommodating space 300 is provided at the bottom of the cabinet 1, which is equipped with a carbon dioxide storage tank 320. In the event of uncontrollable abnormal high temperature, carbon dioxide can be released in time for cooling and combustion suppression. A cooling device 330 is also installed, which can release cold air into the air inlet space 201 to improve the cooling effect on the high-power devices inside the air duct box 60. A smoke generator 340 is also installed, which can release colored smoke in the event of uncontrollable abnormal high temperature, effectively attracting external attention and producing a warning effect.
[0049] The above provides a detailed description of a DC integrated pile provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
