Description

Technical Field

[0002] Due to the compact structure of wall-mounted car charging piles, their heat dissipation structure is only installed on the top of the charging pile cabinet or at the air outlet, and the remaining local heat generation area is assisted by the arrangement of water-cooling pipes to achieve heat dissipation. Due to the mismatch between the thermodynamic path and the spatial structure, this arrangement method is prone to airflow short-circuiting when the output heat dissipation air source does not flow through the heat-generating components. Moreover, the airflow short-circuit area will form a high-temperature eddy current area after mixing with the high-temperature environment generated by the retention at this position, further increasing the local temperature. Therefore, there is a lag in the heat dissipation process in actual application. When the conventional heat dissipation mode is used for processing, it does not have the ability to compensate for the cooling synchronously.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 2As shown, the underground parking wall-mounted new energy vehicle charging pile described in the present invention includes a charging chassis group 1, a water-cooling circulation component 2, a cold source surface transmission component 3 and a heat exchange component 4. An air flow disturbance monitoring component 5 is provided between the cold source surface transmission component 3 and the heat exchange component 4. A heat dissipation air path control module 6 is provided on one side of the heat exchange component 4. The water-cooling circulation component 2 is used to set the cooling medium circulation flow rate during a single heat dissipation corresponding to the heat dissipation required when the internal heat of the charging chassis group 1 is dissipated. Before the water-cooling circulation component 2 distributes the cooling medium circulation flow rate, the current cooling medium circulation flow rate is preset through the heat dissipation air path control module 6. The score corresponding to the flow rate is then monitored by the airflow disturbance monitoring component 5 to obtain the heat dissipation loss caused by the local heat accumulation surface in the charging chassis group 1, and the cooling medium replenishment score is determined according to the heat dissipation loss. The heat dissipation air path control module 6 sends a water path circulation switching signal to the water cooling circulation component 2 according to the cooling medium replenishment score, and then controls the water cooling circulation component 2 to turn on the hot spot diversion pipeline 221, and replenishes the cooling medium circulation flow corresponding to the cold source replenishment score to the local heat accumulation surface through the hot spot diversion pipeline 221, and controls the heat exchange component 4 to perform air-cooled exchange cooling according to the current circulating medium flow compensation score.

[0023] In this embodiment, in order to avoid the mismatch between the thermodynamic path and the spatial structure of the existing charging pile, the output heat dissipation air source is prone to airflow short-circuiting when it does not flow through the heat-generating components, and the airflow short-circuit area will form a high-temperature eddy current area after mixing with the high-temperature environment produced by the retained position, further increasing the local temperature and causing the problem of hysteresis in the heat dissipation process. The present invention proposes an underground parking wall-mounted new energy vehicle charging pile, which pre-sets the score corresponding to the current cooling medium circulation flow through the heat dissipation air path control module 6, and then the airflow disturbance monitoring component 5 monitors and obtains the heat dissipation loss amount generated by the local heat accumulation surface in the charging chassis group 1, and determines the cooling medium replenishment score according to the heat dissipation loss amount, so that the heat dissipation air path control module 6 can send a water circulation switching signal to the water cooling circulation component 2 according to the cooling medium replenishment score, and control the heat exchange component 4 to perform air-cooled exchange cooling according to the current circulating medium flow compensation score, thereby solving the problem of heat dissipation hysteresis.

[0024] In this embodiment, the water cooling circulation component 2, the cold source surface transfer component 3, the heat exchange component 4 and the air flow disturbance monitoring component 5 are all arranged inside the charging chassis group 1, wherein the water cooling circulation component 2, the heat exchange component 4 and the air flow disturbance monitoring component 5 are all arranged at the hot spot generation position inside the charging chassis group 1, and are used for monitoring the heat generation inside the charging chassis group 1 and for cooling treatment during heat dissipation. At the same time, the charging chassis group 1 uses an existing wall-mounted charging pile box. In order not to change the internal space of the charging chassis group 1, the liquid storage pump group 21 is external, and the cooling circulation pipeline 22 and the hot spot diversion pipeline 221 are arranged along the inner wall of the charging chassis group 1 and fixed by snaps.

[0025] In an optional implementation of this embodiment, the water-cooling circulation component 2 includes a liquid storage pump group 21 and a cooling circulation pipeline 22. The liquid storage pump group 21 is used for circulating the cooling medium inside the cooling circulation pipeline 22. The cooling circulation pipeline 22 is installed on the inside of the charging chassis group 1 and covers the surrounding side of the battery module of the charging chassis group 1. There are several hot spot diversion pipelines 221, and they are all connected to the cooling circulation pipeline 22 through solenoid valves. The hot spot diversion pipeline 221 is independently arranged at the gathering place of local hot spots inside the charging chassis group 1, and is used to divert the cooling medium in the cooling circulation pipeline 22 to the gathering place of local hot spots.

[0026] In this embodiment, the hot spot shunt pipeline 221 is arranged at the gathering place of the local hot spots inside the charging chassis group 1, wherein the gathering place of the local hot spots inside the charging chassis group 1 is pre-determined by a wind direction instrument. After the pre-determination by the wind direction instrument, the hot spot shunt pipeline 221 is led out to the gathering place of the retained hot spots, and the cooling circulation pipeline 22 is arranged along the corners of the box frame of the charging chassis group 1 and covers the surrounding side of the battery module of the charging chassis group 1. The cooling circulation pipeline 22 is used for large-area heat dissipation inside the box of the charging chassis group 1 and the heating elements, and the hot spot shunt pipeline 221 is used for cooling the gathering place of the retained hot spots, aiming to eliminate the high-temperature eddy current zone retained at the location where the hot spots are generated.

[0027] In an optional implementation of this embodiment, the cold source surface transmission component 3 includes a liquid cooling plate 31 and a signal controller 32. The liquid cooling plate 31 is arranged on the passing surface of the hot spot diversion pipeline 221, and is used for auxiliary cooling when the hot spot diversion pipeline 221 diverts the cooling medium through. The signal controller 32 is installed at one end of the liquid cooling plate 31, the signal transmission end of the signal controller 32 is connected to the liquid cooling plate 31, and the signal receiving end of the signal controller 32 is connected to the heat dissipation air path control module 6.

[0028] In this embodiment, the liquid cooling plate 31 and the hot spot diversion pipeline 221 are both arranged at the same position inside the charging chassis group 1. When the cooling liquid circulated inside the hot spot diversion pipeline 221 through the cooling circulation pipeline 22 passes through the liquid cooling plate 31, the signal controller 32 receives the start signal sent by the swap scheduling execution unit 64, and controls the liquid cooling plate 31 through the signal controller 32 to adapt to the cooling adjustment amount of the current local hot spot supplementary score to perform auxiliary cooling, so that even if the hot spot diversion pipeline 221 completes the circulation operation at a small flow rate, it will not directly heat up when the cooling water source flows through the hot spot diversion pipeline 221, thereby maintaining the cooling effect when the local hot spot is eliminated.

[0029] In an optional implementation of this embodiment, the heat exchange component 4 includes an air-cooled radiator 41 and an expansion water tank 42. The air-cooled radiator 41 is arranged at the heat dissipation outlet position of the charging chassis group 1, and the expansion water tank 42 is connected to the cooling circulation pipeline 22. The expansion water tank 42 is used to buffer the instantaneous increase in the flow rate of the liquid storage pump group 21 when the hot spot diversion pipeline 221 is switched to a closed state. The air-cooled radiator 41 is connected to the heat dissipation air path control module 6 signal, and one side of the liquid storage pump group 21 intersects with the installation position of the air-cooled radiator 41.

[0030] In this embodiment, after the hot spot is eliminated, when the heat is dissipated over a large area only by adapting the cooling circulation pipeline 22 and the air-cooled radiator 41, the swap scheduling execution unit 64 sends a conduction signal to the expansion water tank 42, so that the expansion water tank 42 and the cooling circulation pipeline 22 are instantly in a connected state, thereby avoiding the problem of the circulating water flow rate and pressure output by the liquid storage pump group 21 to the cooling circulation pipeline 22 increasing instantaneously when the hot spot diversion pipeline 221 is cut off from the conductive state between the cooling circulation pipeline 22, so that the circulating water quickly rushing into the inner side of the cooling circulation pipeline 22 is stored through the reserved space of the expansion water tank 42, thereby maintaining the flow stability during the water circulation switching.

[0031] In an optional implementation of this embodiment, the airflow disturbance monitoring component 5 includes a high-temperature retention surface monitoring unit 51, an airflow short-circuit monitoring unit 52 and a device hot spot surface sensing unit 53. The high-temperature retention surface monitoring unit 51, the airflow short-circuit monitoring unit 52 and the device hot spot surface sensing unit 53 are all arranged on the inner side of the charging chassis group 1. The high-temperature retention surface monitoring unit 51 is used to monitor the local hot spot concentration temperature formed at the arrangement position of the hot spot diversion pipeline 221. The airflow short-circuit monitoring unit 52 is used to monitor the airflow passing through the intersection of the cooling circulation pipeline 22 and the air-cooled radiator 41 to determine whether the reciprocal cooling of the air-cooled radiator 41 is achieved. The device hot spot surface sensing unit 53 is arranged at the flow cooling point inside the charging chassis group 1 to monitor the cooling flow path temperature.

[0032] In this embodiment, the high-temperature retention surface monitoring unit 51 and the device hot spot surface sensing unit 53 use patch-type temperature sensors, and their signal output ends are connected to the supplementary score measurement unit 63. The airflow short-circuit monitoring unit 52 is a static pressure sensor. The airflow short-circuit monitoring unit 52 monitors the airflow passing through the intersection of the cooling circulation pipeline 22 and the air-cooled radiator 41, and determines whether the airflow is retained at the hot spot position of the hot spot diversion pipeline 221. The device hot spot surface sensing units 53 are arranged at equal intervals to the distribution positions of the cooling circulation pipeline 22 and the air-cooled radiator 41 on the inner side of the charging chassis group 1. The device hot spot surface sensing unit 53 is used to measure the temperature of the heat dissipation and cooling area of ​​the path covered by the air-cooled radiator 41 and the cooling circulation pipeline 22, thereby obtaining the internal ambient temperature of the charging chassis group 1.

[0033] In an optional implementation of this embodiment, the heat dissipation air path control module 6 includes a water circulation control unit 61, a cooling score formulating unit 62, a supplementary score measuring unit 63 and a swap scheduling execution unit 64. The water circulation control unit 61, the cooling score formulating unit 62 and the supplementary score measuring unit 63 are all arranged on the inner side of the charging chassis group 1. The water circulation control unit 61 is connected to the cooling circulation pipeline 22 and the hot spot diversion pipeline 221 by signal, and is used to debug the flow direction of the cooling circulation pipeline 22 and the hot spot diversion pipeline 221. The cooling score formulating unit 62 is used to formulate the cooling score according to the current cooling medium circulation flow output by the liquid storage pump group 21. The supplementary score measuring unit 63 reads the monitoring data obtained by the device hot spot surface sensor unit 53 and the cooling score formulated by the cooling score formulating unit 62, and uses them to calculate the compensation score. The swap scheduling execution unit 64 sends a swap cooling debugging signal to the air-cooled radiator 41 based on the compensation score.

[0034] In this embodiment, the working principle of the present invention is as follows: after the device hot spot surface sensing unit 53 obtains the overall ambient temperature of the cooling circulation pipeline 22 inside the charging chassis group 1 and the position covered by the air-cooled radiator 41, the cooling score setting unit 62 reads the data, and analyzes the coolant circulation data of the heat dissipation required by the current overall ambient temperature, sets the cooling medium circulation flow rate during a single heat dissipation (the cooling medium circulation flow rate includes the coolant circulation time, the coolant circulation flow rate, the coolant circulation temperature and the operating air volume of the air-cooled radiator 41), and then the cooling score setting unit 62 sends the cooling medium circulation data to the liquid storage pump group 21 and the air cooling radiator 41. The cold radiator 41 sends an execution signal, and outputs circulating coolant to the cooling circulation pipeline 22 through the liquid storage pump group 21. At the same time, the air-cooled radiator 41 outputs an air source to perform large-scale coverage cooling. If, during the cooling process, the airflow short-circuit monitoring unit 52 monitors the airflow passing through the intersection of the cooling circulation pipeline 22 and the air-cooled radiator 41 and measures the airflow at the hot spot position where the hot spot diversion pipeline 221 is located, and the high-temperature retention surface monitoring unit 51 determines that the heat retained at the current hot spot position exceeds the preset value, then the excess value is sent to the supplementary score determination unit 63, and the supplementary score determination unit 63 is used to calculate the heat retained at the hot spot position. 3 determines the cooling water circulation flow rate that needs to eliminate the excess value, and then adds the score determination unit 63 to send the measured cooling water circulation flow rate to the water circulation control unit 61. The water circulation control unit 61 controls the electromagnetic valve at the connection between the cooling circulation pipeline 22 and the hot spot diversion pipeline 221 to open, and sends a start command to the signal controller 32. The signal controller 32 controls the liquid cooling plate 31 to open, so that the circulating cooling water output by the liquid storage pump group 21 to the inner side of the cooling circulation pipeline 22 is locally diverted through the hot spot diversion pipeline 221. At the same time, the liquid cooling plate 31 locally diverts the hot spot diversion pipeline 221. Auxiliary cooling of the flow position eliminates local retained heat. Since this treatment method will cause the water circulation pressure of the cooling circulation path of the original cooling circulation pipeline 22 to drop, in order to ensure the stability of the cooling of the original coverage area of ​​the cooling circulation pipeline 22, the present invention sets a swap scheduling execution unit 64 to read the supplementary score measured by the supplementary score measurement unit 63, and uses it as the swap cooling debugging value. Thereafter, the air volume of the air-cooled radiator 41 is controlled according to the swap cooling debugging value to increase the wind speed of the air-cooled radiator 41, so that the air-cooled radiator 41 will not operate at high power for a long time, while maintaining the overall heat dissipation effect of the charging chassis group 1.

[0035] In an optional implementation of this embodiment, the cooling circulation pipeline 22 is provided with a single controller 23 and an opening valve 24. The single controller 23 is used to receive the compensation score output by the swap scheduling execution unit 64, and send a control command to the opening valve 24 according to the cooling medium circulation flow after deducting the compensation score in the cooling circulation pipeline 22. The solenoid valve at the connection between the cooling circulation pipeline 22 and the hot spot diversion pipeline 221 is debugged by the opening valve 24 to reduce it to the corresponding opening.

[0036] In an optional implementation of this embodiment, the step of calculating the compensation score by the supplementary score determination unit 63 includes:

[0037] Step S1: The device hot spot surface sensing unit 53 obtains the flow cooling temperature inside the charging chassis group 1 multiple times, and the cooling score setting unit 62 sets a total cooling score based on the hot spot concentration temperature. The proposed total cooling score is set as Ma1, Ma2, Ma3...Man according to the number of acquisitions. The high-temperature retention surface monitoring unit 51 obtains the local hot spot concentration temperature, and the cooling score setting unit 62 sets a cooling compensation score based on the hot spot concentration temperature. The proposed cooling score is set as Mb1, Mb2, Mb3...Mbn according to the set number.

[0038] Step S2: Obtain a proportion y based on the impact of each temperature range on the cooling demand, and multiply the total cooling scores Ma1, Ma2, Ma3...Man obtained multiple times by their corresponding proportions, and then divide them by the total number of total cooling scores obtained to calculate the average.

[0039] Step S3: Add up the obtained multiple groups of temperature reduction compensation scores Mb1, Mb2, Mb3...Mbn and calculate the average value.

[0040] Step S4, performing a difference comparison between the mean parameter of the total cooling score obtained and the mean values ​​of the multiple groups of cooling compensation scores to obtain the swap cooling debugging value; wherein, after obtaining the swap cooling debugging value, the score measurement unit 63 sends the debugging value to the swap scheduling execution unit 64, and the swap scheduling execution unit 64 adjusts the air volume of the air-cooled radiator 41 covering the entire heating element according to the debugging value.
