Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following description is made by way of specific embodiments with reference to the accompanying drawings.
Referring to fig. 1, it shows a flowchart of an implementation of a temperature rise control method for a power supply device according to an embodiment of the present invention, where an execution main body of the temperature rise control method for a power supply device may be a terminal.
The power supply device comprises a transformer and a battery module; power supply equipment is placed in the power cabinet, and in the power cabinet, the transformer is placed in battery module's below, and the air outlet setting of power cabinet is at the top of power cabinet.
The placement of the individual modules of the power supply device in the power cabinet is generally determined by the weight of the individual modules. In order to ensure that the center of gravity of the power cabinet is as low as possible, the heavy modules are usually placed below and the light modules above. Since the battery module is lighter than the transformer, the transformer is placed under the battery module.
The temperature rise control method of the power supply device is detailed as follows:
in S101, the operation mode of the power supply apparatus is acquired.
In S102, if the operating mode of the power supply device is the charging mode, controlling the wind speed of the fan corresponding to the battery module to be smaller than the wind speed of the fan corresponding to the transformer, so that the hot air flow is discharged from the air outlet;
when the working mode of the power supply equipment is a charging mode, the external power supply charges the battery module through the transformer.
In an embodiment of the present invention, the operation mode of the power supply device includes a charging mode and a discharging mode. The power supply apparatus includes a transformer and a battery module. The transformer is input and output sharing, and under different working modes, the transformer can be used as input or output.
When the power supply device works in the charging mode, the external power supply charges the battery module through the transformer. In this case, the transformer is used as an input and is directly connected to an external power supply, and the voltage of the transformer is determined by the external power supply, and there may be cases of high voltage and low voltage. When the voltage of the transformer is low voltage, the current of the transformer is large, the heat is serious, and the transformer needs to be rapidly cooled. However, because the transformer is located below the battery module, in order to ensure that the heat of the transformer can be discharged from the air outlet at the top of the power cabinet, the air speed of the fan corresponding to the battery module is controlled to be smaller than that of the fan corresponding to the transformer, so that the hot air below can be discharged from the air outlet, and the transformer can be cooled.
As can be seen from the above description, in the embodiment of the present invention, when the power supply device is in the charging mode, the wind speed of the fan corresponding to the battery module located above the power cabinet is controlled to be smaller than the wind speed of the fan corresponding to the transformer located below the power cabinet, so that the hot airflow formed by the heat of the transformer can be discharged from the air outlet at the top of the power cabinet, and thus the purpose of cooling the transformer located below the power cabinet is achieved, and the device is prevented from being damaged.
In some embodiments of the present invention, the step of controlling the wind speed of the fan corresponding to the battery module to be less than the wind speed of the fan corresponding to the transformer in S102 may include the following steps:
acquiring operation parameters of a transformer;
determining a first wind speed of a fan corresponding to the transformer based on the operation parameters of the transformer, and controlling the fan corresponding to the transformer to operate at the first wind speed;
determining a second wind speed of the fan corresponding to the battery module according to the first wind speed, and controlling the fan corresponding to the battery module to operate at the second wind speed;
wherein the second wind speed is less than the first wind speed.
In some embodiments of the invention, the operational parameters of the transformer comprise the temperature and/or the load factor of the transformer.
In the embodiment of the invention, in order to control the wind speed of the fan corresponding to the battery module to be smaller than the wind speed of the fan corresponding to the transformer, the real-time wind speed of the fan corresponding to the transformer is determined based on the real-time operation parameters of the transformer, the wind speed is recorded as the first wind speed, and the fan corresponding to the transformer is controlled to operate at the first wind speed. And then determining the real-time wind speed of the fan corresponding to the battery module according to the first wind speed, recording the wind speed as a second wind speed, and controlling the fan corresponding to the battery module to operate at the second wind speed. Wherein the second wind speed is less than the first wind speed.
For example, the first wind speed may be subtracted by a preset value to obtain a second wind speed. The preset value can be calibrated and set according to actual requirements.
The operating parameters of the transformer may include a temperature of the transformer and/or a load factor of the transformer. The first wind speed may be determined by existing methods based on the temperature of the transformer and/or the load factor of the transformer. The higher the temperature of the transformer is, the larger the first wind speed is, the larger the load factor of the transformer is, and the larger the first wind speed is.
In some embodiments of the invention, the power supply apparatus further comprises a rectification module; in the power cabinet, a rectifier module is arranged between a battery module and a transformer;
after obtaining the working mode of the power supply device, the method further comprises the following steps:
if the working mode of the power supply equipment is a charging mode, acquiring the operating parameters of the rectifier module;
determining a third wind speed of the fan corresponding to the rectification module based on the operation parameters of the rectification module, and controlling the fan corresponding to the rectification module to operate at the third wind speed;
when the working mode of the power supply equipment is a charging mode, the external power supply charges the battery module sequentially through the transformer and the rectifying module.
In the charging mode, the rectifier module works to rectify the output of the transformer and charge the battery module.
The operating parameters of the rectifier module may include a temperature of the rectifier module and/or a duty cycle of the rectifier module. In the charging mode, the wind speed of the fan corresponding to the rectifying module can be determined by adopting the existing method according to the temperature of the rectifying module and/or the load rate of the rectifying module, the wind speed is called as a third wind speed, and the fan corresponding to the rectifying module is controlled to operate at the third wind speed.
