Description

Technical Field

[0001] The present application relates to the technical field of energy storage converters, and in particular to an energy storage converter installation box. Background Art

[0002] PCS (Power Conversion System) can control the charging and discharging process of the battery, perform AC / DC conversion, and directly supply power to AC loads without a power grid. PCS consists of a DC / AC bidirectional converter, a control unit, etc. The PCS controller receives background control instructions through communication, and controls the converter to charge or discharge the battery according to the sign and size of the power instruction, thereby adjusting the active power and reactive power of the power grid. The PCS controller communicates with the BMS through the CAN interface to obtain battery pack status information, and can realize protective charging and discharging of the battery to ensure safe battery operation.

[0003] The energy storage inverter is usually installed in a box to protect the energy storage inverter through the box. When the energy storage inverter is working, the electronic components inside it will heat up and generate a lot of heat. In order to ensure the normal operation of the electronic components in the energy storage inverter, it is necessary to dissipate the heat of the energy storage inverter in time. At present, a heat dissipation device is usually set inside the box where the energy storage inverter is installed, and a vent is set on the side wall of the box. The heat generated by the electronic components of the energy storage inverter in the box is dissipated to the outside of the box through the vent by the heat dissipation device in the box, so as to achieve the purpose of dissipating the heat of the energy storage inverter. However, the vent opened on the side wall of the box makes the box have a poor protection effect on the energy storage inverter. For example, when the energy storage inverter installed outdoors encounters rainy and snowy weather, rain and snow will enter the box through the air inlet on the side wall of the box to affect the performance of the energy storage inverter.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0027] refer to Figures 1 to 6The energy storage converter installation box of the present application comprises:

[0028] The installation box 100 has an opening at the top and a partition plate 101 is arranged near the top thereof. The partition plate 101 and the installation box 100 at the bottom thereof together form an installation chamber 300 for installing the energy storage inverter 200. A box door 301 is hinged on the side wall of the installation chamber 300, and a cooling fan 1011 is arranged on the partition plate 101. The box door 301 facilitates the placement of the energy storage inverter 200 into the installation chamber 300, and opening the box door 301 facilitates the inspection and other operations on the energy storage inverter 200 in the installation chamber 300, thereby improving the convenience of using the installation box 100. In addition, a first through hole is opened on the partition plate 101, and a cooling fan 1011 is installed in the first through hole. In order to improve the heat dissipation efficiency of the energy storage inverter 200 in the installation chamber 300, there can be multiple cooling fans 1011. Multiple cooling fans 1011 working at the same time can quickly dissipate the heat in the installation chamber 300, and the specific number of cooling fans 1011 can be set according to actual needs. Therefore, the present application does not make specific limitations on it.

[0029] The protective box 400, the bottom of the protective box 400 is sleeved on the peripheral side of the installation box 100 near its top, the top of the protective box 400 is hinged with a protective cover plate 401, the protective cover plate 401, the protective box 400 and the partition plate 101 together form a heat dissipation chamber 500, and the bottom plate of the protective box 400 is provided with a first heat dissipation hole 402. Among them, in order to improve the heat dissipation efficiency of the energy storage converter 200 in the installation chamber 300, there are multiple first heat dissipation holes 402, and the multiple first heat dissipation holes 402 are evenly distributed on the bottom plate of the protective box 400. The shape and size of the first heat dissipation holes 402 can be set according to actual needs, and the present application does not make specific restrictions on them. Specifically, under the action of the heat dissipation fan 1011, the heat generated by the energy storage converter 200 in the installation chamber 300 during operation is dissipated to the outside of the installation box 100 through the heat dissipation chamber 500 and the first heat dissipation holes 402. In addition, the first heat dissipation hole 402 is opened on the bottom plate of the protective box 400, that is, when the installation box 100 is located outdoors and encounters rainy and snowy weather, rain and snow still fall on the protective box 400 and will not enter the installation chamber 300 and affect the energy storage inverter 200 in the installation chamber 300, thereby improving the protection performance of the energy storage inverter 200 in the installation chamber 300, and further ensuring the working performance of the energy storage inverter 200.

[0030] The energy storage inverter installation box provided in the present application opens the box door 301, installs the energy storage inverter 200 in the installation chamber 300 surrounded by the partition plate 101 and the installation box 100 at the bottom thereof, and then closes the box door 301. The heat generated by the energy storage inverter 200 during operation is dispersed in the installation chamber 300. The cooling fan 1011 is turned on and the heat in the cooling fan 1011 is dissipated to the outside of the installation chamber 300 through the cooling chamber 500 and the first cooling hole 402 by the cooling fan 1011, thereby achieving the purpose of heat dissipation for the energy storage inverter 200. During the above-mentioned heat dissipation process, the energy storage inverter 200 in the installation chamber 300 is protected by the protection box 400 and the first heat dissipation hole 402 is opened on the bottom plate of the protection box 400. That is, when the installation box 100 is located outdoors and encounters rainy and snowy weather, rain and snow still fall on the protection box 400 and will not enter the installation chamber 300 and affect the energy storage inverter 200 in the installation chamber 300, thereby improving the protection performance of the energy storage inverter 200 in the installation chamber 300, and further ensuring the working performance of the energy storage inverter 200.

[0031] In some embodiments, reference Figure 3 , Figure 4 , Figure 5 and Figure 6 , the partition plate 101 in the present application is provided with a second heat dissipation hole 1012; wherein, there may be multiple second heat dissipation holes 1012, and the shape and size of each second heat dissipation hole 1012 may be set according to actual needs. Therefore, the present application does not specifically limit the number of the second heat dissipation holes 1012 and the shape and size of the second heat dissipation holes 1012.

[0032] A heat dissipation pipe 403 is connected to the side wall of the protection box 400, and an exhaust fan 4031 is arranged on the heat dissipation pipe 403. The end of the heat dissipation pipe 403 away from the protection box 400 is connected to a cold air fan 4032, and the cold air outlet of the cold air fan 4032 is connected to the side wall of the installation chamber 300 through the first cold air pipe 600. The heat in the installation chamber 300 is drawn into the heat pipe 403 through the second heat dissipation hole 1012 and the heat dissipation chamber 500 by the induced draft fan 4031, and the hot air in the heat dissipation pipe 403 enters the cold air fan 4032 and is cooled by the cold air fan 4032 before entering the installation chamber 300 from the cold air outlet thereon through the first cold air pipe 600. The cold air enters the installation chamber 300 and exchanges heat with the hot air in the installation chamber 300, so that the temperature in the installation chamber 300 is rapidly reduced. After the cold air enters the installation chamber 300, the energy storage inverter 200 in the installation chamber 300 can be rapidly cooled, so that the temperature of the energy storage inverter 200 itself is rapidly reduced. The induced draft fan 4031 and the cold air fan 4032 work together with the heat dissipation fan 1011 to improve the heat dissipation efficiency in the installation chamber 300.

[0033] In some embodiments, reference Figure 2 The installation box 100 in the present application is provided with an annular tube 102 on the peripheral side near the bottom thereof, and the annular tube 102 is connected to each side wall of the installation chamber 300 through the second cold air duct 700, and the end of the first cold air duct 600 away from the cold air fan 4032 is connected to the annular tube 102; wherein, there are multiple second cold air ducts 700, and the multiple second cold air ducts 700 are evenly distributed between each side wall of the installation chamber 300 and the annular tube 102, and the two ends of the second cold air duct 700 are respectively connected to the annular tube 102 and the side wall of the installation chamber 300, and the arrangement of the annular tube 102 enables the cold air cooled by the cold air fan 4032 to enter the installation chamber 300 through the annular tube 102 and the second cold air duct 700 and be evenly dispersed in the installation chamber 300, thereby improving the heat dissipation efficiency of the energy storage inverter 200 in the installation chamber 300.

[0034] The bottom end of the door 301 is higher than the annular tube 102, so that when the door 301 is opened or closed, the bottom of the door 301 will not collide with the annular tube 102 or the second cold air duct 700, so that the use of the door 301, the annular tube 102 and the second cold air duct 700 will not affect each other.

[0035] In some embodiments, reference Figure 3 In the present application, one end of each second cold air duct 700 connected to the installation chamber 300 is provided with a porous dispersion plate 701. The number of holes on the porous dispersion plate 701, the size of each hole, and the shape of the hole can be set according to actual needs, and the present application does not specifically limit it.

[0036] In the above embodiment, the cold air in the second cold air duct 700 is dispersed through the porous dispersion plate 701 on one end thereof connected to the installation chamber 300, so that the air entering the installation chamber 300 can quickly diffuse in the installation chamber 300 and cool the heat generated by the energy storage inverter 200 in the installation chamber 300, so that the temperature in the installation chamber 300 is quickly reduced to achieve the effect of cooling the energy storage inverter 200 in the installation chamber 300.

[0037] In some embodiments, a filter screen is provided on the first heat dissipation hole 402 in the present application. The filter screen may be made of stainless steel, and parameters such as the size of the filter screen, the number of filter holes, and the aperture of each filter hole (the aperture of the filter screen is smaller than the particle size of the impurities usually filtered, so that the impurities cannot enter the heat dissipation chamber 500 through the first heat dissipation hole 402) can be set according to actual needs, and therefore, the present application does not further limit them.

[0038] In the above embodiment, the filter screen is provided to prevent impurities from passing through the first heat dissipation hole 402 into the heat dissipation chamber 500 and occupying the volume in the heat dissipation chamber 500 to affect the heat flow in the heat dissipation chamber 500. Therefore, the filter screen is provided to improve the heat dissipation efficiency of the energy storage converter 200 in the installation chamber 300.

[0039] In some embodiments, reference Figure 6 The installation box 100 in the present application is provided with a vertical card slot 103 on the side wall near the top thereof, and the partition plate 101 is provided with a card block 1013 matching the vertical card slot 103 , and the card block 1013 can move vertically up and down in the vertical card slot 103 .

[0040] In the above embodiment, after the cooling fan 1011 is installed on the partition plate 101, the partition plate 101 is installed in the installation box 100 by the cooperation between the block 1013 on the partition plate 101 and the card slot 103. After opening the protective cover 401, the partition plate 101 can be pulled out of the installation box 100 under the action of external force, and the cooling fan 1011 on the partition plate 101 can be repaired, cleaned, etc., thereby improving the heat dissipation efficiency of the cooling fan 1011.

[0041] In some embodiments, reference Figure 1 , Figure 2 and Figure 4 In the present application, both the box door 301 and the protective cover plate 401 are provided with a handle 3011. The handle 3011 on the box door 301 facilitates opening or closing the box door 301, and the handle 3011 on the protective cover plate 401 facilitates opening or closing the protective cover plate 401, and the heat dissipation chamber 500 and the installation chamber 300 are cleaned and repaired in time, thereby improving the convenience of covering the box door 301 and the protective cover plate 401.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
