[0002] With the rapid development of industrialization and informatization, energy demand continues to grow, and energy efficiency and environmental impact have become important indicators for measuring technological progress. In this context, the development and application of thermal management technology, as one of the key technologies to improve energy efficiency and reduce environmental impact, is particularly important. Thermal management technology is widely used in electronic equipment, industrial production, transportation and other fields. Its core goal is to control and adjust the temperature of equipment or systems through effective heat exchange methods to ensure its stable operation and extend its service life.
[0003] Traditional thermal management technologies often rely on large amounts of energy input, such as electrically driven fans, which not only increases overall energy consumption but also runs counter to the goal of energy conservation and emission reduction. Especially in urban environments, traditional heat dissipation devices such as fans can generate noise pollution while occupying valuable space resources. At the same time, traditional thermal management systems do not fully utilize recycled heat exchange media, resulting in a waste of resources. In addition, the system may lack an effective storage and replenishment mechanism, and cannot dynamically adjust the amount of heat exchange media according to actual needs. Summary of the invention

In traditional thermal management solutions, fans are a common source of noise, and reducing the use of fans can reduce noise; in this application, the reliance on fans to dissipate heat is reduced, so that noise is reduced.

The second sensor is responsible for monitoring the overall temperature of the heat exchange medium inside the first fluid storage unit and providing real-time data on the medium temperature to optimize the heat exchange efficiency.

[0018] The second fluid storage unit is used to store heat exchange medium; the second fluid storage unit is connected to the heat dissipation unit through a flow channel; the second fluid storage unit, the heat dissipation unit and the heat load device form a loop.
[0019] In the above implementation process, the second fluid storage unit, the heat dissipation unit and the heat load device together form a closed loop, and the heat exchange medium circulates in this loop to achieve continuous transfer and exchange of heat.

[0026] Optionally, the valve of the supplementary unit adjusts the valve opening based on the total amount of heat exchange medium demand Q1, the total amount of heat exchange medium generated Q2, and the total amount of heat exchange medium provided Q3, including:
[0027] When the sum of the total amount of heat exchange medium generated Q2 and the total amount of heat exchange medium provided Q3 is greater than the total amount of heat exchange medium required Q1, the valve opening is 0;
[0028] When the sum of the total amount of heat exchange medium generated Q2 and the total amount of heat exchange medium provided Q3 is less than or equal to the total amount of heat exchange medium required Q1, the valve opening is calculated according to the following rule:
[0029]
[0030] In the above implementation process, the heat exchange system first compares the total amount of heat exchange medium generated Q2 with the total amount of heat exchange medium provided Q3 and the total amount of heat exchange medium demand Q1. When Q2+Q3>Q1, the valve opening is 0; in this case, the system already has enough heat exchange medium to meet the demand, so no additional replenishment is required, and the valve remains closed to avoid oversupply. When Q2+Q3≤Q1, the valve opening is calculated according to the formula P=K×(Q1-Q2-Q3). In this case, the heat exchange system needs additional heat exchange medium to meet the demand, and the valve opening is adjusted according to the difference between demand and supply, so that enough medium is replenished into the heat exchange system. This method improves the efficiency and response speed of heat exchange medium management, reduces energy waste, and improves the stability and reliability of the system.

[0048] In the above implementation process, the first fluid storage unit 221 has two inlets. The first inlet is directly connected to the heat exchange medium recovery device 300. Its main function is to receive the first heat exchange medium (such as car wash wastewater) that has been recovered and processed. The recovered medium is transported to the first fluid storage unit 221 and is prepared for the subsequent heat exchange process, so that the heat exchange medium is recycled and the resource utilization efficiency is improved; the second inlet is connected to the supplementary unit 224, which is used to receive the supplementary second heat exchange medium (such as tap water or other alternative medium). When the amount of heat exchange medium in the system is reduced or needs to be updated, the supplementary unit 224 adds new medium to the storage unit through the second inlet to maintain the heat exchange efficiency of the system. Under different environmental conditions and heat load requirements, the first fluid storage unit 221 can adjust the storage and supply of the heat exchange medium to adapt to the changes. The supplementary unit 224 includes a valve 225, and the opening of the valve 225 is controlled by the controller 100 to adjust the flow of the heat exchange medium. The controller 100 intelligently adjusts the opening of the valve 225 based on real-time monitoring data: the first sensor is specially designed to monitor the liquid level of the heat exchange medium inside the first fluid storage unit 221, and provide real-time storage capacity information of the heat exchange medium; the second sensor is responsible for monitoring the overall temperature of the heat exchange medium inside the first fluid storage unit 221, and providing real-time data on the medium temperature.
[0049] The first fluid storage unit 221 is provided with a heat dissipation unit 223 inside; the heat dissipation unit 223 is connected to the heat load device 210 through a flow channel; wherein the flow channel is used for the circulation of a heat exchange medium; the heat exchange medium performs heat exchange processing with the heat load device 210; the heat dissipation unit 223 is configured to perform heat exchange processing between the heat generated by the heat load device 210 and the heat exchange medium in the first fluid storage unit 221.

[0053] Optionally, based on the usage demand of the second service device 020, the total amount of heat exchange medium demand Q1 required by the heat load device 210 is calculated, including: based on monitoring the temperature of the heat load device 210, counting the usage power of the heat load device 210, the number of heat load devices 210 in use, and the time that the heat load device 210 still needs to be used, and calculating the total amount of heat exchange medium demand Q1 required by the heat load device 210. Based on the usage of the first service device 010, the total amount of heat exchange medium generated by the heat exchange medium recovery device 300 is calculated, including: counting the average usage time of each heat exchange medium recovery device 300, the heat exchange medium generation of each heat exchange medium recovery device 300, the usage time of the heat exchange medium recovery device 300, and the number of heat exchange medium recovery devices 300 in use, and calculating the total amount of heat exchange medium generated by the heat exchange medium recovery device 300.
[0054] In the above implementation process, the controller 100 monitors the temperature of the heat load device 210, counts the power used by the heat load device 210, the number of heat load devices 210 used, and the time that the heat load device 210 needs to be used, and calculates the total amount of heat exchange medium required by the heat load device 210 Q1. Temperature data is the basis for calculating the demand for heat exchange medium, reflecting the current thermal state and cooling demand of the device; power used is a key factor affecting the heat generated by the heat load device 210, and power statistics help predict the heat output and cooling demand of the heat load device 210; the number of heat load devices 210 directly affects the total heat load, and counting the number of uses helps calculate the total amount of heat exchange medium required; the estimated use time helps predict the heat load of the device during the remaining use period, thereby determining the demand for heat exchange medium.

The average usage time provides a typical cycle of operation of each heat exchange medium recovery device 300, which helps to predict the operation mode of the heat exchange medium recovery device 300 and the frequency of heat exchange medium generation; the usage time helps to determine the current state and remaining operation time of the heat exchange medium recovery device 300, thereby predicting the generation amount of heat exchange medium; the number of heat exchange medium recovery devices 300 directly affects the generation amount of heat exchange medium, and counting the usage number helps to calculate the heat exchange demand, so that the recovery and reuse of the heat exchange medium matches the thermal demand of the system, and optimizes the utilization efficiency of resources.
[0056] After calculating Q1, Q2, and Q3, the heat exchange system first compares the total amount of heat exchange medium generated Q2 with the total amount of heat exchange medium provided Q3 and the total amount of heat exchange medium demanded Q1. When Q2+Q3>Q1, the opening of valve 225 is 0; in this case, the system already has enough heat exchange medium to meet the demand, so no additional replenishment is required, and valve 225 remains closed to avoid oversupply. When Q2+Q3≤Q1, the opening of valve 225 is calculated according to the formula P=K×(Q1-Q2-Q3). In this case, the heat exchange system requires additional heat exchange medium to meet the demand, and the opening of valve 225 is adjusted according to the difference between demand and supply, so that sufficient medium is replenished into the heat exchange system. This method improves the efficiency and response speed of heat exchange medium management, reduces energy waste, and improves the stability and reliability of the system.
[0057] It is worth noting that the order of the steps can be exchanged in some cases, for example, ① monitoring the ambient temperature, determining the temperature level according to the temperature range based on the ambient temperature, and obtaining the adjustment coefficient K according to the temperature level; ③ calculating the total amount of heat exchange medium generated Q2 generated by the heat exchange medium recovery device 300 based on the usage of the first service device 010; ② calculating the total amount of heat exchange medium required Q1 required by the heat load device 210 based on the usage demand of the second service device 020; ④ calculating the total amount of heat exchange medium provided Q3 of the supplementary unit 224 based on the liquid level of the total amount of heat exchange medium in the first fluid storage unit 221 and the overall temperature of the heat exchange medium; ⑤ adjusting the opening P of the valve 225 of the supplementary unit 224 based on the total amount of heat exchange medium required Q1, the total amount of heat exchange medium generated Q2 and the total amount of heat exchange medium provided Q3. The above steps ①, ②, ③ and ④ can all be similarly exchanged.
[0058] In one embodiment of the present application, the method is applied to a charging station with a car wash. The specific calculation method of Q1 is as follows: ① Count the charging power P(t) and ΔSOC of each device to be charged in the first t time period. When the vehicle is fully charged, the battery power is P(t)×t / ΔSOC, the remaining amount to be charged is P(t)×t / ΔSOC(1-SOC), and the remaining time to be charged is t / ΔSOC(1-SOC)② Count the number of charging vehicles n1, and sum the remaining charging power, power, and time of each vehicle in ① to obtain the total remaining charging power and charging time of the charging pile③ Combined with the charging module temperature T1, estimate the cooling demand Q1(t,T1) of the charging pile in the future time period.
[0059] In one embodiment of the present application, Q2 is calculated as follows: ① Calculate the average car wash time of each car in the previous t time period t avg ② Count the time t1 that each car wash has washed, and get the remaining time t for each car wash avg -t1③Count the number of vehicles in the car wash n2 and estimate the cooling capacity of the car wash Q2(t) in the future time period.
[0060] In one embodiment of the present application, the ambient temperature is monitored, and the temperature level is determined according to the temperature range based on the ambient temperature, and the adjustment coefficient K is obtained according to the temperature level, wherein the high temperature is 1.2, the normal temperature is 1.1, and the low temperature is 1; when the temperature of the heat load device 210 is T1≤45°C, Q1(t, T1) is 4%-6% of the total charging power, otherwise Q1(t, T1) is (4%-6%)×1.1 of the total charging power; Q2(t)=q×cwater×|(T2+T) / 2-25|, wherein cwater is the specific heat capacity of water; Q3(t)=P×Q 补水 , P ranges from 0 to 1, Q 补水 is the maximum cooling power of the water replenishment device; Q4(t)=Q2(t)+Q3(t); when the liquid level height H is less than 0.9, water replenishment is forced.
