Detailed Description
The present utility model will be further described with reference to the following specific embodiments, and it should be noted that, on the premise of no conflict, new embodiments may be formed by any combination of the embodiments or technical features described below.
In the description of the present utility model, it should be noted that, for the azimuth words such as terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the azimuth and positional relationships are based on the azimuth or positional relationships shown in the drawings, it is merely for convenience of describing the present utility model and simplifying the description, and it is not to be construed as limiting the specific scope of protection of the present utility model that the device or element referred to must have a specific azimuth configuration and operation.
It should be noted that the terms "first," "second," and the like in the description and in the claims are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.
The terms "comprises" and "comprising," along with any variations thereof, in the description and claims, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
As shown in fig. 1 to 5, the present utility model provides an energy storage power supply, which comprises a housing 1, a battery module (not shown in the drawings) and a circuit board module 3, wherein the battery module is arranged in the housing 1, and the circuit board module 3 is arranged above the battery module and is electrically connected with the battery module to control the charging and discharging of the battery module.
As shown in fig. 2-5, the circuit board module 3 includes a circuit board 31, an electronic component 32 disposed on the front surface of the circuit board 31, and an air cooling device 33 disposed on the side surface of the circuit board 31.
As shown in fig. 5, the front surface of the circuit board 31 includes a first mounting region 311, a second mounting region 312, and a third mounting region 313, the first mounting region 311 being located at the middle of the circuit board 31, the second mounting region 312 and the third mounting region 313 being located at both sides of the first mounting region 311. The heat generation amount of the electronic component 32 in the first mounting region 311 is larger than the heat generation amount of the electronic component 32 in the second mounting region 312, and is also larger than the heat generation amount of the electronic component 32 in the third mounting region 313. The air cooling device 33 is opposite to the first mounting region 311 such that the heat dissipation air flow directly passes through the first mounting region 311.
The electronic components 32 with larger heat productivity are concentrated in the middle of the circuit board 31, and the electronic components 32 with smaller heat productivity are distributed on two sides of the circuit board 31, so that the arrangement mode is beneficial to the air cooling device 33 to intensively dissipate heat of the electronic components 32 with larger heat productivity, and the heat dissipation efficiency is improved. The number and the size of the air cooling devices 33 can be reduced, which is beneficial to the miniaturization of the energy storage power supply.
It will be appreciated by those skilled in the art that the housing 1 of the stored energy power source has two oppositely disposed vents 11 to allow air flow into and out of the stored energy power source through the vents 11. The air cooling device 33 is disposed near the ventilation opening 11.
Preferably, the circuit board module 3 further includes a duct cover 34, and the duct cover 34 is covered on the first mounting area 311, so that at least part of the electronic components 32 in the first mounting area 311 are located in the duct cover 34. The air duct cover 34 can prevent heat in the first mounting area 311 from diffusing to two sides, and can guide heat dissipation airflow to accelerate heat dissipation of the heating device.
In one embodiment, the air cooling device 33 includes a first air cooling component 331 and a second air cooling component 332 disposed on two opposite sides of the circuit board 31, the first air cooling component 331 is used for air intake, the second air cooling component 332 is used for air outlet, and when the first air cooling component 331 and the second air cooling component 332 work, an external air flow flows through the first air cooling component 331, the first mounting area 311 and the second air cooling component 332 in sequence. By arranging the two air cooling assemblies oppositely, heat dissipation to the first mounting region 311 can be further accelerated.
Of course, in other embodiments, the first air cooling component 331 may be disposed on only one side of the circuit board 31 for supplying air to the first mounting area 311, or the second air cooling component 332 may be disposed on only one side of the circuit board 31 for exhausting heat from the first mounting area 311.
In one embodiment. As shown in fig. 4, one end of the duct cover 34 extends to the first air cooling assembly 331 such that the first air cooling assembly 331 is located within the duct cover 34. Because the first air cooling component 311 is an air inlet, foreign matters such as dust and the like outside easily enter the energy storage power supply along with the air flow, the dust and the foreign matters entering along with the air flow can be limited in the air duct cover 34, the dust and the foreign matters entering into the air duct cover 34 are prevented from entering the second installation area 312 and the third installation area 313, and the dust entering into the air duct cover 34 can be discharged along with the air flow from the second air cooling component 332, so that the dust and the foreign matters basically cannot be accumulated in the first installation area 311.
Specifically, the inner wall of the air duct cover 34 near one end of the first air cooling component 331 is attached to the outer wall of the first air cooling component 331, so that no gap exists between the air duct cover 34 and the first air cooling component 331.
In some embodiments, the duct cover 34 also covers the second air cooling module 332 inside, so that the external air flow can only pass through the first mounting region 311, but not the second mounting region 312 and the third mounting region 313 through the duct cover 34, which has the advantage of completely preventing external dust from reaching the second mounting region 312 and the third mounting region 313 along with the air flow, but also does not facilitate heat dissipation from the second mounting region 312 and the third mounting region 313.
In other embodiments, a space is provided between the end of the duct cover 34 adjacent to the second air cooling assembly 332 and the second air cooling assembly 332, as shown in fig. 4, that is, a portion of the area of the first mounting area 311 adjacent to the second air cooling assembly 332 is not located in the duct cover 34, so that the second air cooling assembly 332 communicates with the second mounting area 312 and/or the third mounting area 313, and thus the second air cooling assembly 332 can perform a certain heat dissipation function on the second mounting area 312 and/or the third mounting area 313. In this embodiment, although the second air cooling assembly 332 is not disposed within the duct cover 34 such that dust may enter the second and third mounting areas 312, 313 through a gap therebetween, it is negligible to be able to enter the second and third mounting areas 312, 313 given that dust is substantially expelled from the second air cooling assembly 332 with the airflow.
It should be noted that the first air cooling component 331 or the second air cooling component 332 includes at least one fan. In the embodiment shown in fig. 3, 4, and 5, the first air cooling assembly 331 and the second air cooling assembly 332 each include two fans. And the first air cooling component 331 and the second air cooling component 332 are symmetrically disposed at both sides of the circuit board 31.
The duct cover 34 of the present utility model may be made of plastic material, which is advantageous in reducing the overall weight. The duct cover 34 includes a top surface 341 and side surfaces 342 located on both sides of the top surface 341, the top surface 341 is substantially parallel to the circuit board 31, and the side surfaces 342 are substantially perpendicular to the circuit board 31.
In some embodiments, the circuit board module 3 further includes a control board 35 disposed on the front surface of the circuit board 31, the control board 35 is provided with a control circuit of the energy storage power source, the control board 35 is perpendicular to the circuit board 31, and the control board 35 is located in the second mounting area 312 or the third mounting area 313.
Preferably, the control board 35 is disposed adjacent to the first mounting region 311, i.e., the control board 35 is prevented from being disposed adjacent to the edge of the circuit board 31, which is advantageous in reducing damage to the control board 35 during transportation.
In the present utility model, the electronic component 32 provided in the first mounting region 311 includes a MOS transistor, an IGBT transistor, and an auxiliary source circuit. The MOS tube and the IGBT tube are devices with larger heat generation, and preferably, heat dissipation fins 36 are further disposed on the outer sides of the MOS tube and the IGBT tube to accelerate heat dissipation. The auxiliary source circuit further includes a battery side auxiliary source circuit and a high side auxiliary source circuit.
The electronic component 32 in the second mounting area 312 includes a battery connection terminal, a battery side filter circuit, an LLC resonant cavity, and a bus capacitor, wherein the battery connection terminal is used for connecting with a battery module of an energy storage power supply. The electronic component 32 in the third mounting region 313 includes an AC connection terminal, an EMI circuit, an AC switching circuit, an inverter inductance, a bus capacitor, and the like. The AC connection terminal is used for being connected with an external AC power supply or AC electric equipment.
The foregoing has outlined the basic principles, features, and advantages of the present utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made therein without departing from the spirit and scope of the utility model, which is defined by the appended claims.
