Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of charging cabins, and in particular, to a pre-installed liquid-cooled charging cabin for an electric vehicle. Background Art

[0002] Installing the container substation and charging pile unit together on the same steel structure pallet is a pre-installed centralized charging station, which is uniformly deployed in a fixed area of ​​the parking lot to provide charging for vehicles. It is suitable for residential communities, educational schools, administrative agencies, commercial trade circles, industrial plants and military facilities and other industry vehicle applications. It is not affected or restricted by the on-site physical environment and can meet the charging needs of multiple scenarios. When the charging cabin outputs electricity, it will generate high temperatures due to external factors (such as high temperature) and the operation of internal power components, which will affect its normal operation. Therefore, it needs to be cooled and dissipated during actual charging.

[0003] Existing charging cabins generally dissipate heat and cool down through the operation of cooling fans and heat dissipation ports on the cabin body. This cooling method has a good cooling effect under normal circumstances, but when the outside temperature is high, the temperature of the air absorbed by the cooling fan will also be high, making it difficult to achieve rapid heat dissipation of the charging cabinet. When the charging power of the charging cabin is large and the heat is serious, it is also difficult to quickly dissipate the heat out of the cabin body relying solely on the cooling fan, which affects the normal charging of the electric vehicle. Therefore, it is proposed to use liquid cooling to quickly dissipate the heat of the charging cabin. Summary of the invention

During the charging process, the opening and closing door 14 is closed, and the charging line is passed through the charging port 15. The temperature in the charging cavity is monitored by the temperature sensor 9. When the temperature in a charging cavity is too high, the flow rate of coolant and cold air is increased through valve 10 and valve 2 12, so as to quickly and accurately cool the charging cavity, thereby ensuring the cooling effect of the charging cabin and achieving rapid cooling to ensure normal charging.

The coolant flows from top to bottom, which can increase the residence time of the coolant in the cooling pipe network 1 3 and the cooling pipe network 2 4, thereby improving the cooling effect on the cabin 1.

[0031] In order to support and install the electrical components in the distribution cavity, a support plate 8 is fixedly connected to the inside of the distribution cavity. The liquid storage tank 5 is located below the support plate 8. The support plate 8 is provided with a plurality of ventilation holes.

[0032] The air cooling mechanism and the cooling pipe network 3 cooperate to cool the interior of the charging cavity. The air cooling mechanism includes an air cooler 101, a cold air duct 102 and a cold air bin 103.

The air enters the air intake pipe 106 and the air distribution chamber 105 through the air inlet hole. The air enters the cold air pipe 102 and the other air distribution chamber 105 through the air distribution chamber 105, and enters the cold air chamber 103 through the air supply pipe 104 to cool the interior of the cabin 1. The air intake pipe 106 is driven to rotate by the motor 107, thereby driving the air distribution chamber 105 and the multiple cold air pipes 102 to revolve. The cold air pipe 102 drives the driven gear 110 to rotate. Under the action of the outer gear ring 109, the driven gear 110 rotates while revolving with the cold air pipe 102. Through the revolution and rotation of the multiple cold air pipes 102, the coolant in the liquid storage tank 5 is cooled. Stirring is performed to expand the contact between the air and the coolant in the cold air duct 102, thereby improving the cooling effect of the coolant on the air in the cold air duct 102, and further improving the air cooling effect in the cabin 1, and the cold air contacts the cooling pipe network 3 when entering the cold air bin 103, and the coolant in the cooling pipe network 3 further cools the cold air to ensure the low temperature of the cold air, and at the same time, the cold air blows the low-temperature air generated by the cooling pipe network 3 into the interior of the charging cavity, realizing the coordinated cooling of the cold air and the cooling pipe network 3, further enhancing the cooling effect, and the multiple chambers can be connected through the air outlet and the cold air bin 103. Under the action of the air cooler 101, the cold air flows inside each charging cavity and the distribution cavity, so that the cabin 1 is in a lower temperature environment,Reduce the impact of heating of charging piles and electrical components on charging.

[0033] In order to achieve accurate cooling of the corresponding charging chamber, a temperature sensor 9 is installed inside the charging chamber, a valve 10 for controlling the flow of coolant is installed on the cooling pipe network 3, the valve 10 is electrically connected to the temperature sensor 9, the air supply pipe 104 is connected to the reinforcement pipe 11, the reinforcement pipe 11 is connected to the cold air bin 103, the reinforcement pipe 11 is installed with a valve 2 12 for controlling the flow of cold air, the valve 2 12 and the cold air blower 101 are electrically connected to the temperature sensor 9, and the temperature in each charging chamber is monitored by the temperature sensor 9, that is, the heating condition of the charging pile is monitored. During monitoring, when the charging pile works hard and the temperature rises seriously, or the outside temperature is too high, causing the charging chamber to be in a high temperature environment, the temperature sensor 9 transmits an electrical signal to the valve 10, the valve 2 12 and the air cooler 101 to control them to increase the flow rate, so that the coolant quickly flows into the cooling pipe network 13 in the partition 2 on both sides of the corresponding charging chamber, controls the air volume of the air cooler 101 to increase, and at the same time increases the air flow rate of the reinforcing pipe 11 through the valve 2 12, so that more cold air enters the cold air bin 103, increases the cold air volume and air flow rate in the charging chamber, and quickly and accurately cools the charging chamber.

[0034] In order to speed up the flow of cold air in the charging chamber, a cooling fan 13 is installed inside the charging chamber. The cooling fan 13 further increases the air flow rate in the charging chamber, so that the cold air quickly fills the inside of the charging chamber, further improving the cooling effect on the charging pile and the line.

[0036] The working principle or use process of the pre-installed electric vehicle liquid-cooled charging cabin is as follows: The charging pile is installed inside the charging cavity. The car is charged through the electrical components in the power distribution cavity and the charging pile. When charging is needed, the opening and closing door 14 is opened, and the charging line is connected to the car through the charging port 15 to charge. During the charging process, the opening and closing door 14 is in a closed state to reduce the heat exchange between the charging cavity and the outside world. In daily work, the cooling fan 13 can be used to cool the charging chamber. When further cooling is required, the air cooler 101 or the delivery pump 7 is turned on, and air is sent to the inside of the cold air bin 103 through the air cooler 101 to cool the charging cavity by air, or the coolant is delivered to the inside of the cooling pipe network 1 3 and the cooling pipe network 2 4 through the delivery pump 7 to cool the cabin 1 by liquid; When further cooling is required, the air cooler 101 and the delivery pump 7 can be turned on at the same time to cool the cabin 1 in a coordinated manner by combining air cooling and liquid cooling; When the temperature is further reduced, the refrigerator 6 is turned on to circulate and cool the coolant in the liquid storage tank 5, so that the coolant in the cooling pipe network 1 3 and the cooling pipe network 2 4 is in a low temperature state, and the air in the cold air pipe 102 is cooled, thereby improving the cooling effect on the cabin 1; When the temperature sensor 9 senses that the temperature in a charging cavity is too high, the flow of valve 10 and valve 2 12 can be controlled to increase, thereby increasing the amount of coolant entering the corresponding cooling pipe network 3 and the amount of cold air in the corresponding cold air bin 103, thereby quickly cooling the charging cavity.
