Detailed ways

The energy storage converter housing 1 according to the first embodiment of the utility model is described below with reference to FIGS. 1 to 10 .

As shown in FIGS. 1 to 10 , the energy storage converter housing 1 according to the first embodiment of the utility model includes a housing 10 and a partition 2 .

Specifically, the housing 10 includes a door panel 11 and a housing body 12, the door panel 11 and the housing body 12 together define a housing cavity, and the housing 10 has an air inlet 14 and an air outlet 15. The partition 2 is disposed in the housing body 12, and is used to divide the housing cavity into a plurality of mounting cavities 13, at least one of the plurality of mounting cavities 13 has a heat dissipation duct, and the heat dissipation duct is connected to the air inlet 14 and the air outlet 15.

For example, in the examples of Figures 1 to 5, the shape of the shell body 12 is roughly rectangular, but not limited thereto. The door panel 11 is installed on the open side of the shell body 12, and the partition 2 is arranged in the shell 10 at intervals, dividing the accommodating cavity into a plurality of installation cavities 13, and the plurality of installation cavities 13 can be used to install and fix different modules such as transformer modules 4, energy storage converter modules 3, inverter modules 7 or power distribution modules 5, so as to increase the integration of the energy storage converter shell 1, and at the same time make the overall layout of the shell 10 more compact, thereby improving the space utilization rate of the energy storage converter shell 1.

An air inlet 14 and an air outlet 15 are formed on the outer wall of the housing 10, and both the air inlet 14 and the air outlet 15 can connect the inside of the housing 10 with the outside. During the use of the energy storage inverter housing 1, air can enter the housing 10 from the air inlet 14, flow along the heat dissipation duct, and achieve heat exchange with each module. After that, the hot air is discharged from the air outlet 15, thereby dissipating the heat in the internal space of the housing 10, improving the heat dissipation efficiency of the energy storage inverter housing 1, and further improving the operating stability and use safety of each module.

It should be noted that the distance between the partitions 2 can be set according to the size of the modules installed in each installation cavity 13, and is not specifically limited here.

The two sides of the partition 2 are separated to form two completely independent spaces; the two sides of the partition 2 may also be incompletely separated, such as at least one end of the partition 2 is not in contact with the inner wall of the accommodating cavity, that is, there is a gap between the partition 2 and the inner wall of the accommodating cavity. Optionally, the transformer module 4 can be completely isolated to avoid mixed flow between the transformer module 4 and surrounding components.

According to the energy storage converter housing 1 of the embodiment of the utility model, the accommodating cavity is divided into a plurality of installation cavities 13 by the partition 2, and the components with higher heat generation are respectively arranged in different installation cavities 13, which can prevent the components with higher heat generation from generating bypass flow; the housing 10 is provided with an air inlet 14 and an air outlet 15, and the heat dissipation duct is connected with the air inlet 14 and the air outlet 15. Therefore, a heat dissipation duct is arranged for the installation cavity 13 with higher heat generation, and the air can flow along the air inlet 14, the heat dissipation duct and the air outlet 15, thereby conducting heat out of the housing 10, improving the heat dissipation efficiency of the energy storage converter housing 1, and further improving the operation stability and use safety of each module.

According to some embodiments of the utility model, referring to FIG. 1 and FIG. 3, the partition 2 includes a first partition 21, and the plurality of installation cavities 13 include a first installation cavity 131 and a second installation cavity 132. The first installation cavity 131 is suitable for installing the energy storage converter module 3, and the second installation cavity 132 is suitable for installing the transformer module 4. The first partition 21 is arranged between the first installation cavity 131 and the second installation cavity 132. Among them, the energy storage converter module 3 is responsible for the AC/DC bidirectional conversion of each battery cabinet; the transformer module 4 performs step-up and step-down processing for the AC power output and input of the energy storage converter module 3. The energy storage converter module 3 and the transformer module 4 are both used as the main heat source. The energy storage converter module 3 and the transformer module 4 are arranged in different installation cavities 13 to avoid the heat generated by the energy storage converter module 3 and the transformer module 4 interfering with each other's operation, thereby improving the operation stability of the energy storage converter module 3 and the transformer module 4.

Further, as shown in FIG. 1 and FIG. 2 , the heat dissipation duct includes a first heat dissipation duct, and the first heat dissipation duct is arranged in the first installation cavity 131. The air inlet 14 includes a first air inlet 141, and the first air inlet 141 is arranged opposite to the first installation cavity 131, and the first air inlet 141 is connected to the first heat dissipation duct. The top of the shell body 12, the side wall of the shell body 12, and the side surface of the first partition 21 close to the energy storage inverter module 3 are suitable for forming the first heat dissipation duct, and the first heat dissipation duct is suitable for dissipating heat from the energy storage inverter module 3. For example, the first air inlet 141 is formed on the door panel 11, the energy storage inverter module 3 is the main heat source, and the first heat dissipation duct is arranged in the installation cavity 13 where the energy storage inverter module 3 is placed, which is conducive to the outside air to flow to the first installation cavity 131 through the first air inlet 141, and after heat exchange with the energy storage inverter module 3, it is exported to the outside through the air outlet 15. Thereby, heat dissipation of the energy storage converter module 3 is achieved, thereby controlling the temperature of the energy storage converter module 3 and ensuring the operation stability and use safety of the energy storage converter module 3 .

According to some embodiments of the utility model, the partition 2 includes a second partition 22, the first installation cavity 131 includes a third installation cavity 1311 and a fourth installation cavity 1312, the third installation cavity 1311 is suitable for installing the energy storage converter module 3, the fourth installation cavity 1312 is suitable for installing the power distribution module 5, and the second partition 22 is arranged between the third installation cavity 1311 and the fourth installation cavity 1312. Among them, the power distribution module 5 is used to control the on and off of each module. The second partition 22 divides the first installation cavity 131 into the third installation cavity 1311 and the fourth installation cavity 1312 arranged along its width direction, that is, the second partition 22 divides the interior of the housing 10 into two parts, the energy storage converter module 3 is located on the left side of the housing 10, and the power distribution module 5 is located on the right side of the housing 10, reducing the heat exchange between the energy storage converter module 3 and the power distribution module 5, thereby avoiding heat interference and causing the energy storage converter module 3 and the power distribution module 5 to operate incorrectly.

According to some embodiments of the utility model, the heat dissipation duct includes a first sub-heat dissipation duct (for example, the direction indicated by arrow A in FIG. 4 ), and the first sub-heat dissipation duct is arranged in the third installation cavity 1311; the air inlet 14 includes a first sub-air inlet 142, and the first sub-air inlet 142 is arranged opposite to the third installation cavity 1311, and the first sub-air inlet 142 is connected to the first sub-heat dissipation duct, and the first sub-heat dissipation duct is suitable for dissipating heat from the energy storage converter module 3. Among them, the top of the shell body 12, the side wall of the shell body 12, the side surface of the second partition 22 close to the energy storage converter module 3, and part of the first partition 21 are suitable for forming the first sub-heat dissipation duct. External air can flow to the third installation cavity 1311 through the first sub-air inlet 142, and flow out from the air outlet 15 after heat exchange with the energy storage converter module 3, so as to achieve heat dissipation of the energy storage converter module 3.

Further, the heat dissipation duct includes a second sub-heat dissipation duct (for example, the direction indicated by arrow C in FIG. 5 ), and the second sub-heat dissipation duct is arranged in the fourth installation cavity 1312. The air inlet 1414 includes a second sub-air inlet 144, and the second sub-air inlet 144 is arranged opposite to the fourth installation cavity 1312, and the second sub-air inlet 144 is connected to the second sub-heat dissipation duct, and the second sub-heat dissipation duct is suitable for dissipating heat from the power distribution module 5. Among them, the top of the shell body 12, the side wall of the shell body 12, the side surface of the second partition plate 22 close to the power distribution module 5, and part of the first partition plate 21 are suitable for forming the second sub-heat dissipation duct.

Since the power distribution module 5 generates a large amount of heat, a second sub-heat dissipation duct is arranged in the installation cavity 13 near the power distribution module 5. The air enters the fourth installation cavity 1312 from the second sub-air inlet 144, and flows along the second sub-heat dissipation duct to achieve heat exchange with the power distribution module 5. The hot air is then discharged from the air outlet 15, thereby improving the heat dissipation efficiency of the power distribution module 5, and further improving the operating stability and use safety of the power distribution module 5.

According to some embodiments of the utility model, the air outlet 15 includes a first air outlet 151, the first air outlet 151 is connected to the first sub-heat dissipation duct, and the first air outlet 151 is arranged opposite to the third installation cavity 1311; and/or the first air outlet 151 is connected to the second heat dissipation duct, and the first air outlet 151 is arranged opposite to the fourth installation cavity 1312. For example, there may be two first air outlets 151, the two first air outlets 151 are respectively connected to the first sub-heat dissipation air duct and the second heat dissipation air duct, and the two first air outlets 151 are arranged opposite to the third installation cavity 1311 and the fourth installation cavity 1312; or, there may be one first air outlet 151, the first air outlet 151 is connected to the first sub-heat dissipation air duct and the second heat dissipation air duct at the same time, and the first air outlet 151 is arranged opposite to the third installation cavity 1311 and the fourth installation cavity 1312 at the same time; or again, there may be one first air outlet 151, the first air outlet 151 is connected to the first sub-heat dissipation air duct or the second heat dissipation air duct, and the first air outlet 151 is arranged opposite to the third installation cavity 1311 or the fourth installation cavity 1312.

3, 4 and 7, there are two first air outlets 151, one of which is arranged opposite to the third installation cavity 1311, and the housing 10 further comprises a first duct member 16, which is arranged on the housing body 12, and has a first air outlet duct, the end of which is the first air outlet 151, and the first duct member 16 extends obliquely in a direction away from the first partition 21. In this arrangement, the first duct member 16 increases the structural stability of the first air outlet duct, and at the same time, the first duct member 16 extends obliquely in a direction away from the first partition 21, guiding the hot air flowing along the first air outlet duct, and at the same time, preventing external water from entering the third installation cavity 1311 along the first air outlet duct, thereby avoiding interference with the energy storage converter module 3.

Referring to Figures 3, 4 and 6, another first air outlet 151 is arranged opposite to the fourth installation cavity 1312, and the housing 10 further includes a second air duct member 17, which is arranged on the shell body 12, and the second air duct member 17 has a second air outlet duct, and the two ends of the second air outlet duct are divided into an air inlet end and a first air outlet 151, and the first air outlet 151 is located below the air inlet end, and a fan 171 is arranged at the air inlet end. Among them, when the fan 171 is running, a negative pressure is generated in the fourth installation cavity 1312, and the air is strengthened to enter the fourth installation cavity 1312 from the second air inlet 142, and the air flows in the second heat dissipation duct, so as to realize heat exchange with the power distribution module 5, and then the hot air is discharged from the second air outlet duct, so as to form air flow in the fourth installation cavity 1312 to improve the heat dissipation efficiency of the power distribution module 5.

Further, referring to FIG6 , in the thickness direction of the housing 10 (e.g., the front-to-back direction in FIG1 ), the cross-sectional area of the second air duct member 17 gradually decreases in the direction toward the power distribution module 5. That is, the cross-sectional area of the second air duct member 17 on the side toward the power distribution module 5 is the smallest, and the cross-sectional area of the second air duct member 17 on the side away from the power distribution module 5 is the largest, and the fan 171 is arranged on the side with the largest cross-sectional area of the second air duct member 17. Such an arrangement is conducive to the flow of air in the fourth installation cavity 1312, thereby increasing the heat dissipation efficiency of the power distribution module 5.

6, the bottom wall of the second air duct member 17 extends obliquely toward the power distribution module 5 in the thickness direction of the housing 10. That is, the second air outlet duct extends obliquely in a direction away from the center of the housing 10. This arrangement prevents external water from entering the fourth installation cavity 1312 along the second air outlet duct, thereby avoiding interference with the power distribution module 5.

According to some embodiments of the utility model, the heat dissipation air duct includes a second heat dissipation air duct, and the second heat dissipation air duct is arranged in the second installation cavity 132. The air inlet 14 includes a second air inlet 143, and the second air inlet 143 is arranged opposite to the second installation cavity 132. The second air inlet 143 is connected to the second heat dissipation air duct (for example, the direction indicated by the arrow B in Figures 4 and 5).

The hot air is then discharged from the air outlet 15, thereby improving the heat dissipation efficiency of the transformer module 4, and further improving the operating stability and safety of the transformer module 4.

Furthermore, the inverter module 7 is suitable for being arranged between the transformer module 4 and the door panel 11, and the side wall of the shell body 12, the side surface of the first partition plate 21 close to the transformer module 4, the side surface of the inverter module 7 close to the door panel 11, and the side surface of the inverter module 7 close to the transformer module 4 are suitable for forming a second heat dissipation duct, and the second heat dissipation duct is suitable for dissipating heat from the transformer module 4 and the inverter module 7. The inverter module 7 is used for AC power distribution, DC power distribution and confluence.

The partition 2 further includes a fourth partition 24 and a fifth partition 25. The fourth partition 24 is arranged in the second mounting cavity 132, and divides the second mounting cavity 132 into a fifth mounting cavity 1321 and a sixth mounting cavity 1322 arranged along the thickness direction of the housing 10.

The fifth partition 25 is arranged in the second mounting cavity 132, and the fifth partition 25 is located on the side of the transformer module 4 adjacent to the first partition 21. The inverter module 7 is fixedly installed in the fifth mounting cavity 1321 to avoid interference between the inverter module 7 and the transformer module 4, and reduce heat transfer between the inverter module 7 and the transformer module 4.

Among them, the transformer module 4, the fourth partition 25, the inverter module 7 and the housing 10 jointly define a second heat dissipation duct (for example, the direction indicated by the arrow B in FIG. 4 ). The fourth partition 24, the inverter module 7, the second partition 22, the fifth partition 25 and the housing 10 jointly define a third heat dissipation duct (for example, the direction indicated by the arrow D in FIG. 4 and FIG. 5 ). The air can flow along the second heat dissipation duct, thereby realizing heat dissipation of the transformer module 4. At the same time, the air can also pass through the inverter module 7 along the third heat dissipation duct, and the inverter module 7 can be cooled, thereby improving the operating stability of the inverter module 7.

In addition, in the examples of Figures 1, 3-5, due to the large mass of the transformer module 4, the bottom of the transformer module 4 is installed on the bottom wall of the shell 10, the fifth partition 25 is adjacent to the first partition 21, and the fifth partition 25 is parallel to the first partition 21, so that the heat generated by the transformer module 4 and the energy storage inverter module 3 can be transferred to the air flowing between the first partition 21 and the fifth partition 25, so that the third heat dissipation duct can further enhance the heat dissipation of the transformer module 4 and the energy storage inverter module 3.

According to some embodiments of the utility model, the air outlet 15 includes a second air outlet 152, the second air outlet 152 is connected to the second heat dissipation air duct, and the second air outlet 152 is arranged opposite to the second installation cavity 132. In this way, the outside air can flow to the second installation cavity 132 through the second air inlet 142, and after heat exchange with the transformer module 4, it is exported to the outside through the second air outlet 152; similarly, the outside air can flow to the inverter module 7 through the second air inlet 142, and after heat exchange with the inverter module 7, continue to flow between the first partition 21 and the fifth partition 25, and heat exchange the heat generated by the transformer module 4 and the energy storage converter module 3, and then the hot air is exported to the outside through the second air outlet 152. In this way, the heat dissipation of the transformer module 4, the inverter module 7, the transformer module 4 and the energy storage converter module 3 is achieved, so as to control the temperature of the transformer module 4, the inverter module 7, the transformer module 4 and the energy storage converter module 3.

Further, referring to Figures 3, 4 and 8, the housing 10 further includes a third duct member 18, which is disposed on the housing body 12 and has a third air outlet duct, and the structure of the third duct member 18 is the same as that of the second duct member 17. Thus, the fan 171 is used to generate negative pressure in the second installation cavity 132, and the air is strengthened to enter from the second air outlet 152, and the air flows in the third heat dissipation duct and the fourth heat dissipation duct, so as to achieve heat exchange with each module, and then the hot air is led out from the third air outlet duct, so as to form air flow in the second installation cavity 132 to improve the heat dissipation efficiency of the energy storage converter housing 1.

The communication module 6 is used to communicate and connect various modules to achieve remote maintenance, remote alarm, remote control, remote collection, etc. The third partition 23 divides the third installation cavity 1311 into two parts, the upper and lower parts, the power distribution module 5 is located in the upper part of the third installation cavity 1311 (i.e., the first sub-installation cavity 13111), and the communication module 6 is located in the lower part of the third installation cavity 1311 (i.e., the second sub-installation cavity 13112), thereby reducing the heat exchange between the power distribution module 5 and the communication module 6.

According to some embodiments of the utility model, the housing 10 has a first direction (e.g., the up-down direction in FIG. 1 ) and a second direction (e.g., the left-right direction in FIG. 1 ) that are orthogonal to each other, the first installation cavity 131 and the second installation cavity 132 are arranged along the first direction, and the third installation cavity 1311 and the fourth installation cavity 1312 are arranged along the second direction. In this way, the energy storage converter module 3 and the power distribution module 5 are both located in the upper part of the housing 10 and are spaced apart, and the transformer module 4 is located in the lower part of the housing 10, reducing the heat exchange between the energy storage converter module 3 and the transformer module 4, thereby avoiding heat interference and causing errors in the operation of the energy storage converter module 3 and the transformer module 4.

According to some embodiments of the utility model, the partition 2 is provided with a heat insulation device 211, and the heat insulation device 211 is used to prevent heat from being transferred between the installation cavities 13. In other words, the heat insulation device 211 can prevent heat from being transferred between the installation cavities 13 on both sides of the partition 2. Among them, a module with a main heat source can be placed in the installation cavity 13 on one side of the partition 2, and a module that is not easy to generate heat can be placed in the installation cavity 13 on the other side of the partition 2. Thus, the heat insulation device 211 is used to reduce the heat transfer between the modules on both sides of the partition 2, so that the modules do not interfere with each other, and further ensure that the modules on both sides of the partition 2 can operate stably.

At least one of the multiple partitions 2 is disposed adjacent to the energy storage converter module 3. By disposing a partition 2 having a heat insulation layer 213 at a position adjacent to the energy storage converter module 3, the heat transfer between the first mounting cavity 131 and the mounting cavity 13 adjacent thereto is reduced, thereby ensuring the operational stability of the energy storage converter module 3 and the modules adjacent thereto. At least one of the multiple partitions 2 is disposed adjacent to the transformer module 4. By disposing a partition 2 having a heat insulation layer 213 at a position adjacent to the transformer module 4, the heat transfer between the second mounting cavity 132 and the mounting cavity 13 adjacent thereto is reduced, thereby ensuring the operational stability of the transformer module 4 and the modules adjacent thereto.

In some optional embodiments, the heat insulation device 211 is heat insulation cotton. Among them, the heat insulation cotton has many advantages such as flame retardancy, non-toxicity, corrosion resistance, small bulk density, low thermal conductivity, strong chemical stability, low moisture absorption rate, good hydrophobicity, etc. Using heat insulation cotton as the heat insulation device 211 has a good heat insulation effect and is conducive to the lightweight design of the energy storage converter housing 1.

According to some specific embodiments of the present invention, a seal 19 is provided between the air outlet 15 and the side wall of the housing 10. Thus, the sealing between the air outlet 15 and the side wall of the housing 10 is increased, and external water is prevented from flowing into the housing 10 through the gap between the air outlet 15 and the side wall of the housing 10, thereby improving the operating safety of each module inside the housing 10.

According to some embodiments of the utility model, the waterproof level of the third installation cavity 1311 is lower than the waterproof levels of the second installation cavity 132 and the fourth installation cavity 1312. Since the transformer module 4 is installed in the second installation cavity 132, the power distribution module 5 is installed in the fourth installation cavity 1312, and the energy storage converter module 3 is installed in the third installation cavity 1311, the transformer module 4 and the power distribution module are prone to leakage or short circuit when exposed to water.

3. As shown in FIG. 4 , the air flows through the second heat dissipation duct B: the operation of the fan 171 generates a negative pressure in the second installation cavity 132 , causing the outside air to flow into the second installation cavity 132 through the second air inlet 143 , and after heat exchange with the transformer module 4 , the air is guided to the outside through the third air outlet duct 123 ;

4. As shown in FIG. 4 and FIG. 5 , the air flows through the third heat dissipation duct D: the operation of the fan 171 generates a negative pressure in the second installation cavity 132, causing the outside air to flow to the fifth installation cavity 1321 through the second air inlet 143, and after exchanging heat with the inverter module 7, it continues to flow between the first partition plate 21 and the fifth partition plate 25, exchanges heat with the heat generated by the transformer module 4 and the energy storage converter module 3, and then the hot air is discharged to the outside through the third air outlet duct.
