[0001] The present application relates to but is not limited to the field of energy management technology, and specifically refers to an energy management system. Background Art

[0002] At present, the heat dissipation of the inverter is mainly achieved by installing an additional radiator and using the radiator to dissipate heat naturally, or by adding a fan to the radiator to achieve air cooling.

[0036] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0037] like Figure 1 As shown, an embodiment of the present application provides an energy management system, including: an inverter 1, a water tower 2, a water pump 3, a water supply system 4 and a control valve assembly.

[0038] The inverter 1 is provided with a heat exchange channel 111. The heat exchange channel 111 is for water to flow, and the water exchanges heat with the inverter 1, so as to take away the heat generated by the inverter 1, thereby achieving water cooling of the inverter 1. The heat exchange channel 111 has a first inlet 17 and a first outlet 18. The first inlet 17 is for water to flow into the heat exchange channel 111, and the first outlet 18 is for water in the heat exchange channel 111 to flow out.

[0039] The water tower 2 has a second inlet 21 and a second outlet 22. The second inlet 21 supplies water to flow into the water tower 2, and the second outlet 22 supplies water in the water tower 2 to flow out of the water tower 2. The second inlet 21 is configured to be able to communicate with the first outlet 18, and the second outlet 22 is configured to be able to communicate with the first inlet 17, so that the water tower 2 can be connected to the heat exchange flow channel 111 to form a first heat exchange circuit.

[0040] Water pump 3 (such as Figure 7As shown) is connected to the heat exchange channel 111 and is configured to drive the water in the heat exchange channel 111 to flow.

[0041] The water supply system 4 is configured to be in communication with the first inlet 17 to deliver water to the heat exchange flow channel 111. The water supply system 4 may be a whole-house water supply system 4, such as tap water.

[0042] The control valve assembly is configured to control the on-off of the first heat exchange circuit and the on-off between the water supply system 4 and the first inlet 17 .

[0043] In this way, when the inverter 1 needs to dissipate heat, the control valve assembly can connect the first inlet 17 and the second outlet 22, and connect the first outlet 18 and the second inlet 21, so that the first heat exchange loop flows, and water can flow in the first heat exchange loop to achieve water cooling of the inverter 1. When the amount of water in the water tower 2 is insufficient, or the water temperature in the water tower 2 is relatively high and insufficient for the inverter 1 to dissipate heat, the control valve assembly can connect the water supply system 4 and the first inlet 17, and use the water supply system 4 to transport relatively low temperature cold water to the heat exchange channel 111 to ensure the heat dissipation effect of the inverter 1.

[0044] Compared with natural heat dissipation and air cooling, water cooling has higher heat dissipation efficiency, so this solution is beneficial to improving the heat dissipation efficiency of the inverter 1; and the fan can be omitted, which is beneficial to reducing the operating noise of the inverter 1.

[0045] In some exemplary embodiments, Figure 1 As shown, the energy management system further includes: a water heater 5. The water heater 5 has a third inlet 51, and the third inlet 51 supplies water to flow into the water heater 5. The third inlet 51 is configured to be able to communicate with the first outlet 18, so that the heat exchange flow channel 111 can transport water to the water heater 5. The control valve assembly is also configured to control the opening and closing between the third inlet 51 and the first outlet 18.

[0046] In this way, when the temperature of the inverter 1 is relatively high, the water temperature in the heat exchange channel 111 is also high. At this time, the control valve assembly can connect the third inlet 51 and the first outlet 18, so that the hot water in the heat exchange channel 111 can enter the water heater 5. This is equivalent to recovering the heat generated by the inverter 1 through the water heater 5, realizing the waste heat recovery. Compared with directly dissipating the heat generated by the inverter 1 into the environment, this solution is conducive to improving the energy utilization rate of the energy management system.

[0047] In some exemplary embodiments, Figure 1 As shown, the water heater 5 has a third outlet 52, and the third outlet 52 is for hot water in the water heater 5 to flow out. The third outlet 52 is configured to be able to communicate with the first inlet 17, so that the water heater 5 can deliver water to the heat exchange flow channel 111. The control valve assembly is also configured to control the connection and disconnection between the third outlet 52 and the first inlet 17.

[0048] In this way, in extremely low temperature weather, the control valve assembly can connect the third outlet 52 with the first inlet 17, so that the water heater 5 can deliver hot water to the heat exchange channel 111 of the inverter 1, which plays a preheating and heat preservation role for the inverter 1, so as to ensure that the inverter 1 can be cold-started and can work at a suitable temperature. This is equivalent to the inverter 1 having a preheating protection mechanism in extremely cold weather.

[0049] In some exemplary embodiments, Figure 1 As shown, the control valve assembly includes: a first control valve 71 and a second control valve 72 .

[0050] The first control valve 71 has a first output port 714, a first input port 711, a second input port 712 and a third input port 713. The first output port 714 is connected to the first inlet 17, the first input port 711 is connected to the water supply system 4, the second input port 712 is connected to the second outlet 22, and the third input port 713 is connected to the third outlet 52.

[0051] The second control valve 72 has a fourth input port 721 , a second output port 722 , and a third output port 723 . The fourth input port 721 communicates with the first outlet 18 , the second output port 722 communicates with the second inlet 21 , and the third output port 723 communicates with the third inlet 51 .

[0052] In other words, the first control valve 71 and the second control valve 72 are both multi-way valves, which are beneficial for reducing the number of control valves and simplifying the pipeline layout of the energy management system.

[0053] Of course, the first control valve 71 may also include multiple control valves, and the second control valve 72 may also include multiple control valves.

[0054] In some exemplary embodiments, Figure 1 and Figure 6 As shown, the energy management system further includes: a heat storage device 6. The heat storage device 6 has a fourth inlet 61 and a fourth outlet 62. The fourth inlet 61 supplies water into the heat storage device 6, and the fourth outlet 62 allows water in the heat storage device 6 to flow out. The fourth inlet 61 and the fourth outlet 62 are configured to be able to communicate with the first outlet 18 and the second inlet 21 respectively, so that the heat storage device 6 can be connected with the water tower 2 and the heat exchange flow channel 111 to form a second heat exchange circuit.

[0055] In this way, when the temperature of the inverter 1 is relatively high, the water temperature in the heat exchange channel 111 is also high. At this time, the control valve assembly can connect the fourth inlet 61 with the first outlet 18, and connect the fourth outlet 62 with the second inlet 21, so that the hot water in the heat exchange channel 111 can enter the heat storage device 6. This is equivalent to recovering the heat generated by the inverter 1 through the heat storage device 6, realizing the waste heat recovery. Compared with directly dissipating the heat generated by the inverter 1 into the environment, this solution is conducive to improving the energy utilization rate of the energy management system.

[0056] The heat stored in the heat storage device 6 can be used for heating of users, such as wall-mounted heaters, floor heating, etc. The second inlet 21 of the water tower 2 can be only one, or can include multiple sub-inlets, one of which is connected to the second output port 722 of the second control valve 72, and the other sub-inlet is connected to the fourth outlet 62 of the heat storage device 6.

[0057] In some exemplary embodiments, Figure 1 As shown, the control valve assembly includes a second control valve 72. The second control valve 72 also has a fourth output port 724, and the fourth output port 724 is connected to the fourth inlet 61. In other words, both the first control valve 71 and the second control valve 72 can be four-way valves, such as Figure 8 shown.

[0058] This helps to improve the integration of the control valve assembly and simplify the piping layout of the energy management system.

[0059] In some exemplary embodiments, Figure 1 As shown, the energy management system further includes: a photovoltaic panel 8, which is electrically connected to the inverter 1. The inverter 1 can collect information such as the power generation efficiency of the photovoltaic panel 8.

[0060] The second outlet 22 is connected to a cleaning pipeline 81, which is configured to clean the photovoltaic panel 8. The control valve assembly further includes a third control valve 73, which is configured to control the on-off of the cleaning pipeline 81. The third control valve 73 may be a two-way valve disposed on the cleaning pipeline 81, such as Fig. 9 shown.

[0061] In this way, when the power generation efficiency of the photovoltaic panel 8 is relatively low, the water in the water tower 2 can be used to clean the photovoltaic panel 8, thereby achieving automatic cleaning of the photovoltaic panel 8, which is beneficial to improving the power generation efficiency of the photovoltaic panel 8.

[0062] The second outlet 22 of the water tower 2 may have only one or may include multiple sub-outlets, one of which is connected to the second input port 712 of the first control valve 71 , and another of which is connected to the cleaning pipeline 81 .

[0063] In some exemplary embodiments, a water filter device (not shown) is provided at the second outlet 22 of the water tower 2, so that the water discharged from the water tower 2 will be filtered by the water filter device before flowing to other structures, which is helpful to avoid pipe blockage or scaling.

[0064] In some exemplary embodiments, Figures 2 to 5 As shown, the inverter 1 includes: a box body 11. The inverter 1 may also include a box cover 12, a cover plate 13, a side cover 14, an IGBT 15, a temperature sensor 16 and other structures. The box body 11 may include a bottom plate and four side plates, such as Figure 4 As shown, the housing 11 can enclose an installation cavity. The heat exchange flow channel can be arranged on the bottom plate. IGBT15, temperature sensor 16 and other structures are installed in the installation cavity and fixed on the housing 11. The housing cover 12 and the cover plate 13 can be respectively covered on both sides of the thickness direction of the housing 11. The first inlet 17 and the first outlet 18 of the housing 11 can be respectively arranged on the opposite sides of the housing 11. The number of side covers 14 can be two, and the two side covers 14 are respectively covered on the sides where the first inlet 17 and the first outlet 18 of the housing 11 are located.

[0065] The box body 11 is a heat conducting member, and the box body 11 is provided with a heat exchange flow channel 111. Figure 3 shown.

[0066] In other words, the heat exchange channel 111 is formed integrally with the housing 11. This can save the need for an additional radiator, which is beneficial to reducing the volume of the inverter 1, and further beneficial to reducing the transportation cost and installation difficulty of the inverter 1. In addition, the housing 11 itself is a heat conducting member and can also be used for heat dissipation, which is beneficial to improving the heat dissipation efficiency of the inverter 1.

[0067] In the related art, in order to ensure the heat dissipation effect, the radiator of the inverter 1 is usually made relatively large, large in volume, and very heavy, with relatively high manufacturing, installation and transportation costs, and poor user experience. However, by adopting the solution of the present application, the radiator can be omitted, so that the thickness of the inverter 1 can be reduced by about 40%, the weight can be reduced by about 30%, the structure is simpler, and the manufacturing, installation and transportation costs are correspondingly reduced.

[0068] In some exemplary embodiments, the box 11 is provided with a high-heating area and a low-heating area, such as Figure 4 and Figure 6 The distribution density of the heat exchange flow channel 111 in the high heat generation area is greater than that in the low heat generation area.

[0069] In the related art, the natural heat dissipation method easily makes it difficult to dissipate heat at the local high-temperature position of the inverter 1, which easily causes the inverter 1 to work at a reduced rating at high temperature. The air-cooled heat dissipation effect is also not particularly ideal for the local high-temperature position, and the fan is prone to break down when the operating temperature is high, and there is a certain amount of noise during operation.

[0070] The embodiment of the present application dissipates heat from the inverter 1 by water cooling. The heating temperature of the heating device can be tested, and the required water flow volume can be calculated according to the heat conduction formula Q=cm△t, so as to accurately calculate the flow area of ​​the heat exchange flow channel 111 required for each heating area, and then determine the distribution density of the heat exchange flow channel 111 in the high heating area and the low heating area. Through precise temperature control, the inverter 1 can always be kept in the optimal operating temperature range of 10°C to 50°C.

[0071] In some exemplary embodiments, Figure 4 As shown, the heat exchange channel 111 includes a plurality of sub-channels 1111 arranged in parallel. The sub-channels 1111 located in the high heat generation area are arranged in a serpentine shape, and the sub-channels 1111 located in the low heat generation area are arranged in a straight line shape.

[0072] The inlets of the plurality of sub-channels 1111 may be connected via a shunt pipe, and the outlets of the plurality of sub-channels 1111 may be connected via a header pipe. The shunt pipe and the header pipe may be integrated on the cover plate 13 of the inverter 1.

[0073] The energy management system works as follows:

[0074] Intelligent temperature control and the reuse of heat generated by the inverter 1 are realized through intelligent linkage between the inverter 1 and the water tower 2, the water supply system 4, the water heater 5, and the heat storage device 6. The inverter 1 is provided with a conformal temperature control pipeline (i.e., the heat exchange flow channel 111) according to the arrangement of the internal components. In the high-heat generating area such as the IGBT 15, a pipeline cross-sectional area with sufficient water flow is arranged according to the heat to be taken away, so as to ensure that the temperature at the waterway outlet (i.e., the first outlet 18) of the inverter 1 is controlled below 50°C. The waterway inlet (i.e., the first inlet 17) of the inverter 1 is connected to the first waterway controller, and the first waterway controller is provided with a four-way valve (i.e., the first control valve 71), and the outlet (i.e., the first output port 714) of the four-way valve is connected to the inverter 1. The first waterway controller is provided with three inlets (i.e., the first input port 711, the second input port 712, and the third input port 713), and the connection of the three inlets is intelligently controlled by the four-way valve. The first inlet (i.e., the first input port 711) is connected to the whole house water supply system 4. This waterway is opened and works when the water temperature and water volume in the water tower 2 do not meet the cooling requirements. The second inlet (i.e., the second input port 712) is connected to the water outlet of the water tower 2 (i.e., the second outlet 22). This waterway is the loop of the entire circulation system. It is a circulating waterway used under normal conditions and when the water level of the water tower 2 is above the safety line. It is a waterway that is preferentially connected. The third inlet (i.e., the third input port 713) is connected to the water outlet of the water heater 5 (i.e., the third outlet 52). This waterway is connected in extremely low temperature weather to protect the cold start of the inverter 1. The outlet of the inverter 1 (i.e., the first outlet 18) is connected to the second waterway controller, and the second waterway controller is provided with a four-way valve (i.e., the second control valve 72). The inlet of the second water circuit controller (i.e., the fourth input port 721) is connected to the outlet of the inverter 1 (i.e., the first outlet 18), and the second water circuit controller is provided with three outlets (i.e., the second output port 722, the third output port 723, and the fourth output port 724). The first outlet (i.e., the third output port 723) is connected to the inlet of the water heater 5 (i.e., the third inlet 51), and the hot water from the inverter 1 is first used to fill the water heater 5. The second outlet of the second water circuit controller (i.e., the fourth output port 724) is connected to the heat storage device 6. In winter or other times when there is a demand for heat and the water heater 5 is full, the second outlet is connected, and the hot water stores the heat through the heat storage device 6 for the user to use. After passing through the heat storage device 6, the water flows to the water tower 2. The third outlet of the second water circuit controller (i.e., the second output port 722) is directly connected to the water tower 2. When the water heater 5 is full and there is no demand for heat storage, the third outlet is opened, and the water flows directly to the water tower 2. After completing the heat exchange, the water in the water tower 2 flows back to the first water circuit controller after passing through the water filter device, and then flows to the inverter 1 to form a circulation loop. The temperature data is collected by the temperature sensor 16 set in the inverter 1 to control the flow rate of the water in the waterway. This temperature control method can ensure that the inverter 1 always operates at the optimal operating temperature (10°C-45°C).A three-way valve is provided at the water outlet of the water heater 5, and the outlet is divided into two paths, one for users to take hot water, and the other flows to the first water path controller. This water path is connected in weather of minus 10°C or below to provide preheating protection for the operation of the inverter 1, especially during cold start. The water tower 2 is provided with a pipeline (i.e., cleaning pipeline 81) connected to the photovoltaic panel 8. By monitoring the photovoltaic power generation current and voltage data passing through the inverter 1, the water path is opened to automatically clean the photovoltaic panel 8 when the power generation efficiency of the photovoltaic panel 8 is reduced.

[0075] The control logic of the thermal management system can be referred to Fig.10 shown.

[0076] The thermal management system has the following beneficial effects:

[0077] 1) The water-cooled temperature control system can dissipate heat better. By testing the heating temperature of the heating device and calculating the water flow volume according to the heat conduction formula Q=cm△t, the number and cross-sectional area of ​​the conformal cooling pipes can be accurately arranged, so that the temperature can be accurately controlled, so that the inverter 1 always maintains the optimal operating temperature of 10 degrees Celsius to 50 degrees Celsius.

[0078] 2) The aluminum radiator in the related art can be removed, the box body 11 is integrally formed and provided with a water channel (i.e., heat exchange channel 111), and the four sides of the box body 11 can also participate in heat dissipation. At the same time, the thickness of the inverter 1 will be reduced by about 40%, the weight will be reduced by about 30%, the structure will be simpler, and the corresponding cost will be reduced.

[0079] 3) Linked with the water supply system 4, the heat on the inverter 1 is transported away by water flow, and the emitted heat is reused through the water heater 5 and the heat storage device 6, so that the energy utilization rate is higher and it is more energy-saving and environmentally friendly.

[0080] 4) Linked with the water heater 5, it can ensure that the inverter 1 has a preheating protection mechanism in extremely cold weather.

[0081] 5) Through the intelligent linkage between the inverter 1 and the water supply system 4, the inverter 1 collects the power generation efficiency information of the photovoltaic panel 8, and starts the water cleaning mode for the photovoltaic panel 8 according to the collected information to ensure the power generation efficiency of the photovoltaic panel 8.
