Detailed Description
The following are specific embodiments of the present invention and the technical solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
As shown in fig. 1-11, an energy storage battery cabinet, comprising: the cabinet body 100, the air duct unit and the air conditioner 200, wherein the cabinet body 100 comprises a first area 110 and a second area 120 which are sequentially distributed front and back along a first direction, the second area 120 comprises at least two rows of longitudinal spaces 130, and each longitudinal space 130 is sequentially distributed along a second direction; two adjacent longitudinal spaces 130 form a mounting unit in which a first longitudinal passage 140 is provided at a side of one longitudinal space 130, a second longitudinal passage 150 is provided between the two longitudinal spaces 130, and a third longitudinal passage 160 is provided at a side of the other longitudinal space 130; the top end of the mounting unit is provided with an air duct unit which is communicated with the first longitudinal channel 140, the second longitudinal channel 150 and the third longitudinal channel 160; the air conditioner 200 is installed at the top of the cabinet 100, the air conditioner 200 includes an internal circulation air inlet 210 and an internal circulation air outlet 220, the internal circulation air inlet 210 is communicated with the top of the first region 110, the internal circulation air outlet 220 is communicated with the first longitudinal channel 140, the second longitudinal channel 150 and the third longitudinal channel 160 through an air duct unit, and the air duct unit is configured to distribute the air flow blown out by the internal circulation air outlet 220 to the top of the first longitudinal channel 140, the top of the second longitudinal channel 150 and the top of the third longitudinal channel 160 according to a set proportion.
The energy storage battery cabinet and the energy storage battery 400 are part of a new energy storage system, and the working principle of the new energy storage system is as follows: the electric energy generated by the power generation system can be stored in the energy storage battery 400, the energy storage battery 400 releases the electric energy according to the requirement, in the process, the energy storage battery 400 maintains a certain working temperature through the battery cabinet, for example, when the temperature is too high (the electric core releases heat when the energy storage battery 400 works), the electric core needs to be cooled, and when the temperature is too low, the electric core needs to be heated.
In this embodiment, the air conditioner 200 is designed in an overhead manner, that is, the air conditioner 200 is installed at the top of the cabinet 100, so that the occupied space is small, and the air conditioner 200 can perform cooling and/or heating by implementing the temperature adjusting function of the air conditioner 200. Because the exhaust fan of the energy storage battery 400 is located on the panel thereof, after the energy storage battery 400 is installed in place, the exhaust fan thereof is exhausted forward, so that the first region 110 is located at the front side of the interior of the cabinet 100, the second region 120 is located at the rear side of the interior of the cabinet 100, the first region 110 and the second region 120 are separated to form two relatively closed spaces under the condition of filling the energy storage battery 400, the air conditioner 200 establishes a closed internal circulation between the first region 110 and the second region 120 through the internal circulation air inlet 210 and the internal circulation air outlet 220, and the whole process operates in the closed space of the cabinet 100, so that the air in the cabinet 100 can be continuously circulated and reused, thereby reducing the loss of the cold air flow or the hot air flow.
The longitudinal spaces 130 are spaces extending along the third direction (Z-axis direction), and the number of the longitudinal spaces 130 is plural, it is to be understood that in this embodiment, two adjacent longitudinal spaces 130 are taken as one mounting unit, at least one group of mounting units (i.e. two adjacent longitudinal spaces 130 are included) is included in the second region 120, two sides of each longitudinal space 130 are reserved with longitudinal channels, the longitudinal channels are communicated with the longitudinal spaces 130, one longitudinal channel is shared between two adjacent longitudinal spaces 130, and each longitudinal air channel is communicated with the air channel unit, so that the air channel unit can input air flow to two sides (i.e. the longitudinal channels) of each longitudinal space 130, so that the air channel unit can suck the air flow laterally from the energy storage battery 400.
Taking heat dissipation of the energy storage battery 400 as an example, the energy storage battery 400 discharges hot air into the first area 110, and the internal circulation air inlet 210 of the air conditioner 200 sucks the hot air and then blows cold air into the second area 120. The air duct unit may guide cool air blown from the air conditioner 200 to three longitudinal channels at both sides of the longitudinal space 130 accommodating the energy storage cells 400, and then enter the respective energy storage cells 400 from the longitudinal channels to cool the battery cells.
It should be noted that, the cold air in the present embodiment is not directly blown onto the energy storage battery 400, but is guided into the first longitudinal channel 140, the second longitudinal channel 150 and the third longitudinal channel 160 through the air channel space, so as to improve the distribution of the cooling medium (air flow), avoid blocking the air flow by the energy storage battery 400, avoid generating vortex, and optimize the uniformity of heat dissipation.
On the basis of the above embodiment, the first longitudinal channel 140 is provided with at least one first fan 141 for enhancing the movement of the air flow, the second longitudinal channel 150 is provided with at least one second fan 151 for enhancing the movement of the air flow, and the third longitudinal channel 160 is provided with at least one third fan 161 for enhancing the movement of the air flow.
It should be noted that, in the present embodiment, the first direction, the second direction, and the third direction are different, where the first direction may be preferably a front-to-back direction (i.e., a Y-axis direction) of the cabinet 100, the second direction may be preferably a width direction (i.e., an X-axis direction) of the cabinet 100, and the third direction may be preferably a height direction (i.e., a Z-axis direction) of the cabinet 100; it is understood that the above is only one specific embodiment of the first direction, the second direction and the third direction, and that the first direction, the second direction and the third direction are other directions within the scope of the present disclosure. It should be noted that, when the first fan 141, the second fan 151, and the third fan 161 are plural, each of the first fan 141, the second fan 151, and the third fan 161 is sequentially arranged along the third direction (vertical direction).
Since the internal circulation air outlet 220 discharges air downwards from the top end of each longitudinal channel, the side walls of the energy storage batteries 400 arranged from top to bottom in each longitudinal space 130 suck air flow, so that the air flow has a phenomenon of loss and slow flow speed in the longitudinal direction, which results in uneven temperature distribution of the longitudinal channels in the longitudinal direction, and a relatively obvious temperature difference exists between the upper temperature and the lower temperature of the second region 120 from the practical simulation effect, in this embodiment, a fan is arranged in the region between the middle part and the bottom of each longitudinal channel, and blows air downwards through the fan, so that the flowability of the air flow in the longitudinal channels is enhanced in a relay manner, and in the example, the fan forces the air flow at the upper part in the longitudinal channels to blow down, so that the temperature difference in the longitudinal direction is reduced.
The space occupied by the air conditioner 200 is saved, the air outlet of the air conditioner 200 is guided to two sides of the longitudinal space 130 through the air duct unit, the energy storage batteries 400 can be fed with air from two sides and are led to the first area 110, the first area 110 and the second area 120 form a closed internal circulation system, and the air flow movement is strengthened in a relay manner through the fan so as to reduce the temperature difference between the energy storage batteries 400 in the longitudinal direction.
As shown in fig. 1-6 and fig. 9-11, the air duct unit includes a main air duct 310, a first secondary air duct 330, a second secondary air duct 340 and a third secondary air duct 350, the main air duct 310 is provided with a total air inlet 320, the internal circulation air outlet 220 is communicated with the total air inlet 320, the total air inlet 320 is composed of a first air inlet 321, a second air inlet 322 and a third air inlet 323, the first secondary air duct 330 is communicated with the top end of the first longitudinal channel 140, the second secondary air duct 340 is communicated with the top end of the second longitudinal channel 150, and the third secondary air duct 350 is communicated with the top end of the third longitudinal channel 160;
the main air duct 310 includes a first air guiding channel 313, a second air guiding channel 314 and a third air guiding channel 315, one end of the first air guiding channel 313 is a first air inlet 321, the other end of the first air guiding channel is communicated with the first secondary air duct 330, one end of the second air guiding channel 314 is a second air inlet 322, the other end of the second air guiding channel is communicated with the second secondary air duct 340, one end of the third air guiding channel 315 is a third air inlet 323, and the other end of the third air guiding channel is communicated with the third secondary air duct 350.
For example, the main air duct 310 is a hollow groove extending along the second direction (X-axis direction), the first secondary air duct 330, the second secondary air duct 340 and the third secondary air duct 350 are all structures of channels extending along the first direction and are all located at the bottom of the main air duct 310, the main air duct 310 is provided with a total air inlet 320 on the upper surface thereof, the total air inlet 320 is further divided into a first air inlet 321, a second air inlet 322 and a third air inlet 323, and when the total air inlet 320 is used for air intake, the total air inlet 320 is split into the first air guide channel 313, the second air guide channel 314 and the third air guide channel 315 through the first air inlet 321, the second air inlet 322 and the third air inlet 323, and is distributed into the first longitudinal channel 140, the second longitudinal channel 150 and the third longitudinal channel 160.
It should be noted that, through this air duct structure of this embodiment, the problem of poor flow distribution after the air conditioner 200 air-out is solved smartly, and the air current can not be blocked by the energy storage battery 400, but guide distribution through the main air duct 310 and each secondary air duct smartly, so the velocity of flow of the air current can not be influenced, so the generation of vortex is avoided, and the phenomenon of uneven temperature caused by local heat dissipation degradation is prevented.
In addition, because the air conditioner 200 is designed as a top-mounted air conditioner, the internal circulation air outlet 220 of the air conditioner 200 is located at the top of the second area 120, and if the air flow directly enters the second area 120, the air flow directly blows the top battery, so that the flow speed of the air flow is reduced, the air flow cannot approach the bottom battery, the temperature distribution of the second area 120 is uneven, and the air flow is conveyed to each longitudinal channel, so that the above problem can be solved.
