Description

Technical Field

[0001] This utility model relates to the field of charging devices, and in particular to an intelligent thermal management high-efficiency DC charging box and charging device. Background Technology

[0002] In the current booming development of the new energy vehicle industry, charging piles, as core infrastructure, are of paramount importance in terms of performance and stability. During operation, various power devices, especially charging modules, generate a significant amount of heat; in severe weather conditions, this can also lead to moisture buildup inside the charging pile. Excessive internal temperature and humidity not only drastically reduce charging efficiency but also accelerate the aging of electronic components, severely impacting their lifespan and potentially causing safety accidents. Currently, common temperature and humidity control methods for charging piles on the market have many drawbacks. Traditional air-cooling methods only provide ventilation without dehumidification, resulting in limited heat dissipation efficiency and easily introducing external moisture into the enclosure, making it difficult to meet the heat dissipation requirements of high-power charging piles; single liquid cooling systems are costly and complex to maintain. Furthermore, existing temperature control systems generally lack intelligent adjustment capabilities, failing to flexibly and accurately adjust temperature control strategies based on the real-time operating status of the charging pile and changes in ambient temperature. This leads to either poor temperature control or excessive energy consumption under different operating conditions. Utility Model Content

[0042] A charging device using the aforementioned intelligent thermal management high-efficiency DC charging housing.

[0043] Working Principle: When the temperature is high, the temperature sensor 401 sends an electrical signal to the temperature controller 402. The temperature controller 402 is electrically connected to the charging controller 6 to form a circuit. The charging controller 6 outputs a 12V voltage to control the power supply of the KA1 coil, causing the normally open contact to close and start the adjustable speed cooling fan 2. The adjustable speed cooling fan 2 dissipates heat from the housing 1 to the outside, reducing the internal temperature of the housing 1. The temperature controller 402 can adjust the power of the adjustable speed cooling fan 2 based on the PWM signal of the temperature collected by the temperature sensor 401. The dust filter covers 9 installed on the left and right side doors 101 can block dust from entering the housing 1, thereby maintaining ventilation inside the casing and preventing frequent temperature rises inside the charging pile housing, thus reducing unnecessary losses. When the humidity inside the charging unit 1 is high, the principle is similar to heat dissipation. The humidity sensor 501 sends an electrical signal to the humidity controller 502. The humidity controller 502 is electrically connected to the charging controller 6 to form a circuit. The charging controller 6 outputs a 12V voltage to control the KA2 coil for power supply. The normally open contact closes, starting the dehumidifier 503 to expel water vapor from the charging unit, keeping the interior dry and preventing accelerated aging of electronic components and shortened lifespan due to excessive air humidity and temperature. The dehumidifier 503 stops working once the humidity controller 502 detects that the humidity has dropped below the set value.
