Description

Technical Field

[0001] This utility model belongs to the field of charging pile technology, and relates to a heat dissipation system based on air conditioning and a high-power charging pile. Background Technology

[0002] A charging station is a dedicated charging device that provides electrical replenishment for new energy vehicles, similar in function to a gas pump at a traditional gas station. Among the various performance parameters of a charging station, charging power directly affects charging speed and user experience. Higher charging power results in shorter charging time. High-power charging stations can effectively reduce user waiting time, while the heat dissipation performance of the charging station is a key factor limiting charging power.

[0003] Existing charging piles typically use either air cooling or liquid cooling for heat dissipation. Liquid cooling has higher heat dissipation efficiency, but cavitation occurs when the coolant temperature is ≥45℃, and the heat exchange efficiency will decrease significantly at this temperature. This requires additional cooling towers. In addition, liquid cooling systems are extremely expensive, making it difficult to popularize them on a large scale. Furthermore, it is necessary to strictly prevent coolant leakage, which places extremely high demands on sealing.

[0004] Compared to liquid cooling, air cooling has advantages such as lower cost, ease of large-scale deployment, and no risk of cavitation or leakage. For example, an invention patent with application number CN201910637429.4, entitled "A Heat Dissipation Method and Circulating Heat Dissipation Structure for a Charging Pile," describes a heat dissipation structure that uses an industrial air conditioner-like internal circulation cooling method to remove heat generated by the power module inside the charging pile, thereby reducing the internal temperature of the charging pile and improving heat dissipation efficiency. External air does not participate in the internal air circulation of the charging pile.

[0005] However, the above-mentioned heat dissipation structure has some defects. Since the heat dissipation structure adopts an internal circulation mode, it is necessary to separate the cold air duct and the hot air duct inside the charging pile through a partition. The cold air can only come into contact with a local area of ​​the power module, which means that the area far away from the air inlet cannot exchange heat sufficiently. In addition, the airflow that the area far away from the air inlet comes into contact with is already heated. The reduced temperature difference leads to a sharp drop in heat dissipation efficiency and extremely poor heat dissipation uniformity. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an air conditioning-based heat dissipation system and a high-power charging pile.

[0007] The objective of this utility model can be achieved through the following technical solution: a heat dissipation system based on air conditioning, comprising:

[0008] A first door panel has an installation cavity inside. The inner side of the first door panel is provided with a first through hole area and a second through hole area, and the outer side of the first door panel is provided with a third through hole area. The first through hole area, the second through hole area and the third through hole area are all connected to the installation cavity.

[0009] An air conditioning module is disposed in the mounting cavity of the first door panel. The air outlet of the air conditioning module is aligned with the first through hole area, the air inlet of the air conditioning module is aligned with the second through hole area, and the air exhaust outlet of the air conditioning module is aligned with the third through hole area.

[0010] The air duct has an air inlet end that is aligned with the inner side of the first door panel and the first through hole area. The air outlet of the air conditioning module is connected to the air inlet end of the air duct through the first through hole area.

[0011] Preferably, the air duct has a flared structure, with the air inlet end of the air duct being larger than the air outlet end, and the diameter of the air duct gradually decreasing from the air inlet end to the air outlet end.

[0012] Preferably, the system also includes a modular compartment, with a cold air inlet and a hot air outlet at opposite ends, and the air outlet of the duct is connected to the cold air inlet of the modular compartment.

[0013] Preferably, it also includes an exhaust module, which is connected to the hot air outlet of the module compartment, and the exhaust module includes a plurality of exhaust fans arranged in an array.

[0014] Preferably, it also includes a second door panel, with the first door panel and the second door panel located on opposite sides of the module compartment, and the exhaust module installed on the inner side of the second door panel.

[0015] Preferably, a temperature difference sensor is installed inside the module compartment.

[0016] Preferably, the air conditioning module is an industrial air conditioner.

[0017] Preferably, the system also includes a control module and a temperature sensor, wherein the temperature sensor is electrically connected to the control module, and the control module is electrically connected to the air conditioning module.

[0018] A high-power charging pile includes the air conditioning-based heat dissipation system and a charging module, which is disposed in a module compartment.

[0019] Preferably, it also includes a cabinet, the module compartment is disposed in the cabinet, and the first door panel and the second door panel are respectively hinged to both sides of the cabinet.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. The heat dissipation system adopts a design that draws in outside air for cooling and then sends it into the charging module. The air inlet of the air conditioning module can obtain outside air through the second through hole area, and the air outlet of the air conditioning module can send cold air into the air duct through the first through hole area. The air duct can accurately guide the cold air directly to the heat sink area of ​​the charging module, effectively improving the heat dissipation efficiency and uniformity.

[0022] 2. The flared structure of the air duct accelerates airflow speed through a tapered design (from the inlet to the outlet), utilizing the Venturi effect (fluid velocity increases and pressure decreases in a narrow cross-section) to enhance the kinetic energy of the airflow within the duct. After entering from the inlet, the cold air is accelerated through the narrow conical area, forming a high-pressure, high-speed airflow, which is then ejected from the outlet, directly acting on the charging module. This increased airflow speed further enhances the cooling effect.

[0023] 3. The control module can control the start / stop or power of the air conditioning module. The temperature sensor is used to monitor the temperature of the module compartment in real time. The control module automatically starts / stops the air conditioning or adjusts the cooling intensity according to the set threshold, and achieves the effect of automatic cooling when the temperature of the charging pile reaches the threshold.

Detailed Implementation

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] like Figures 1 to 7 As shown, an air conditioning-based heat dissipation system includes:

[0034] The first door panel 100 has a mounting cavity 110 inside. The inner side of the first door panel 100 is provided with a first through hole area 120 and a second through hole area 130. The outer side of the first door panel 100 is provided with a third through hole area 140. The first through hole area 120, the second through hole area 130 and the third through hole area 140 are all connected to the mounting cavity 110.

[0035] Air conditioning module 200 is installed in the mounting cavity 110 of the first door panel 100. The air outlet of the air conditioning module 200 is aligned with the first through hole area 120, the air inlet of the air conditioning module 200 is aligned with the second through hole area 130, and the air exhaust outlet of the air conditioning module 200 is aligned with the third through hole area 140.

[0036] The air duct 300 has an air inlet end that is connected to the inner side of the first door panel 100 and aligned with the first through hole area 120. The air outlet of the air conditioning module 200 is connected to the air inlet end of the air duct 300 through the first through hole area 120.

[0037] The first door panel 100 has an internal mounting cavity 110 for accommodating the air conditioning module 200. Preferably, the air conditioning module 200 is an industrial air conditioner. The through-hole area is a perforated area with several micro-holes for airflow through the wall of the first door panel 100. Cold air is discharged from the air conditioning module 200 and enters the air duct 300 through the first through-hole area 120 to cool the charging module 700. Outside air can enter the air conditioning module 200 through the second through-hole area 130 for heat exchange. The hot exhaust gas generated by the air conditioning module 200 is discharged into the external environment through the third through-hole area 140.

[0038] The air duct 300 is used to guide the cold air generated by the air conditioning module 200 to the target area (such as the heat sink area of ​​the charging module 700). The design of the air duct 300 can ensure low wind resistance and uniform airflow distribution. Through the guidance of the air duct 300, the cold air can be accurately delivered to the area that needs to be cooled, and the cold air can pass through the area where the charging module 700 is located, rather than being directly discharged to the area around the charging module 700, which effectively improves heat dissipation efficiency and uniformity.

[0039] The air conditioning module 200 directly introduces outside air through the second through-hole area 130, avoiding heat accumulation caused by internal air circulation. The cold air enters the air duct 300 through the first through-hole area 120, and is then precisely guided by the air duct 300 to the heat sink area of ​​the charging module 700, realizing the function of precise airflow guidance, so that the cold air directly cools the charging module 700, effectively improving heat dissipation efficiency and uniformity.

[0040] Compared to the internal circulation cooling structure, the cold air in this cooling system exchanges heat with the charging module 700 to form hot air, which then leaves the charging module 700 directly. Therefore, the cold air and hot air will not mix together, ensuring the stability and efficiency of the cooling effect.

[0041] Based on the above implementation method, the air duct 300 has a flared structure, with the air inlet end of the air duct 300 being larger than the air outlet end, and the diameter of the air duct 300 gradually decreasing from the air inlet end to the air outlet end.

[0042] The flared structure of the air duct 300 accelerates the airflow speed through a tapered design (from the inlet to the outlet), utilizing the Venturi effect (fluid velocity increases and pressure decreases in a narrow cross-section) to enhance the kinetic energy of the airflow within the air duct 300. After entering from the inlet, the cold air is accelerated through the narrow conical region, forming a high-pressure, high-speed airflow, which is then ejected from the outlet, directly acting on the charging module 700. This further enhances the cooling effect by increasing the airflow velocity.

[0043] like Figures 1 to 4 As shown, based on the above implementation method, it also includes a module compartment 400. The two opposite ends of the module compartment 400 are a cold air inlet end 410 and a hot air outlet end 420, respectively. The air outlet end of the air duct 300 is connected to the cold air inlet end 410 of the module compartment 400.

[0044] The module compartment 400 houses the charging module 700. Its cold air inlet 410 connects to the air outlet of the duct 300 to receive cold air from the air conditioner, while its hot air outlet 420 discharges heated air. The module compartment 400, through its cold air inlet 410 and hot air outlet 420, forms a unidirectional forced-air cooling channel, creating a front-blowing, rear-exhausting air cooling mode. This allows cold air to pass through the interior of the module compartment 400, achieving directional ventilation, effectively avoiding dead zones, and improving heat dissipation efficiency.

[0045] like Figures 1 to 5 As shown, based on the above-described embodiments, an exhaust module 500 is also included. The exhaust module 500 is connected to the hot air outlet 420 of the module compartment 400. The exhaust module 500 includes a plurality of exhaust fans 510 arranged in an array.

[0046] The exhaust module 500 can actively draw in air to create negative pressure at the rear of the module compartment 400, drawing in hot air and promoting a continuous inflow of cool air. Multiple exhaust fans 510 can draw in air more evenly, improve the air exchange rate, and quickly remove heat.

[0047] like Figures 1 to 7 As shown, based on the above embodiment, a second door panel 600 is also included. The first door panel 100 and the second door panel 600 are located on opposite sides of the module compartment 400, and the exhaust module 500 is installed on the inner side of the second door panel 600.

[0048] The first door panel 100 integrates an air conditioning module 200, and the second door panel 600 integrates an exhaust module 500, forming a through-type cooling channel structure that supplies cold air on one side and extracts hot air on the other side.

[0049] Based on the above implementation method, a temperature difference sensor is installed inside the module compartment 400. The temperature difference sensor is used to detect the temperature difference between different locations, and based on the obtained temperature difference data, it determines whether the heat dissipation is uniform, whether there are local hot spots, and other information, thereby achieving refined temperature monitoring and improving system safety and stability.

[0050] Based on the above implementation, it also includes a control module and a temperature sensor. The temperature sensor is located externally and is electrically connected to the control module. The control module is electrically connected to the air conditioning module 200.

[0051] A temperature sensor is used to monitor the outside temperature in real time, and the control module can control the start / stop or power of the air conditioning module 200. When the outside temperature does not reach the threshold (when the air temperature is not high), the air conditioning module 200 does not cool, and air cooling is achieved through natural wind from the outside. When the outside temperature reaches the threshold (when the air temperature is high), the control module automatically turns on the cooling function of the air conditioning module 200 according to the set threshold, thereby providing cooling air.

[0052] like Figures 1 to 7 As shown, based on the above embodiments, a high-power charging pile includes an air conditioning-based heat dissipation system and a charging module 700, which is disposed in a module compartment 400.

[0053] The charging module 700, as the main heat source during the charging process, internally contains key components such as AC / DC power supplies, rectifiers, DC-DC / AC-DC converters, IGBT power modules, and inductors. Furthermore, the charging module 700 is formed by stacking several module units within the module compartment 400. High-power charging piles generate a large amount of heat during operation. The air conditioning module 200 actively cools the module, forcing cold air into the unidirectional forced-air cooling channel within the module compartment 400 in conjunction with the air duct 300, thereby cooling the charging module 700. After heat exchange between the cold air and the charging module 700, hot air is formed and flows out from the hot air outlet 420, then is discharged to the outside by the exhaust module 500.

[0054] Based on the above implementation method, it also includes a cabinet 800, a module compartment 400 disposed inside the cabinet 800, and a first door panel 100 and a second door panel 600 respectively hinged to both sides of the cabinet 800.

[0055] The cabinet 800, the first door panel 100, and the second door panel 600 form a complete enclosed cabinet structure. Both the first door panel 100 and the second door panel 600 can be opened for easy maintenance of the air conditioning module 200 and the exhaust module 500.

[0056] The charging pile integrates an industrial air conditioning module 200 within the first door panel 100, and combines it with a directional horn-shaped air duct 300, a module compartment 400 forced exhaust module 500, and an intelligent temperature control mechanism to achieve efficient active heat dissipation of the high-power charging module 700. This ensures that cool air is precisely delivered to the heat-generating area and hot air is orderly discharged to the outside of the equipment, forming a through-flow forced convection circulation.

[0057] In this example, under extreme operating conditions with ambient temperatures reaching 48℃, the cooling system can stably control the operating temperature of the 360kW high-power charging module 700 at 32℃, effectively suppressing temperature rise and preventing power derating or shutdown protection due to overheating, thus ensuring long-term stable operation of the equipment at full power output. Furthermore, this cooling system enables the charging station to operate in harsh outdoor environments such as high temperature, high humidity, and dust.

[0058] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0059] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0060] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0061] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
