According to an embodiment of the present application, a first embodiment of a heat dissipation method of an in-vehicle wireless charger is provided, which can be executed by a computer program in a heat dissipation controller. Referring to fig. 2, the following steps may be included:
step S201: when the mobile terminal is charged by the vehicle-mounted wireless charger, the real-time temperature of the vehicle-mounted wireless charger is acquired through the temperature sensor.
When the charging of the mobile terminal by the vehicle-mounted wireless charger is confirmed, a collecting instruction is sent to the temperature sensor, so that the temperature sensor can collect the real-time temperature in the vehicle-mounted wireless charger.
Have charging coil and power circuit in the on-vehicle wireless charger, in the charging process, charging coil and power circuit can give off a large amount of heats. The temperature sensor can be arranged near a charging coil and a power circuit in the vehicle-mounted wireless charger so as to acquire the real-time temperature in the vehicle-mounted wireless charger.
The temperature sensor is transmitted to the heat dissipation controller through the connecting wire after acquiring the real-time temperature in the vehicle-mounted wireless charger.
Step S202: whether the vehicle-mounted wireless charger needs to be actively cooled is judged based on the acquired real-time temperature. If necessary, the process proceeds to step S203, otherwise, the process proceeds to step S201.
The present embodiment provides three determination methods:
the first method comprises the following steps: and judging whether the acquired real-time temperature is greater than a first temperature threshold value, and if so, determining that the vehicle-mounted wireless charger needs to be actively cooled.
The first temperature threshold value is prestored in the heat dissipation controller, and if the acquired real-time temperature is greater than the first temperature threshold value, the fact that the real-time temperature in the vehicle-mounted wireless charger is too high is indicated, and active heat dissipation is required.
And the second method comprises the following steps: and calculating the temperature rising speed based on the collected real-time temperature and the historical collected temperature, judging whether the temperature rising speed is greater than a rising speed threshold value, and if so, determining that the vehicle-mounted wireless charger needs to be actively radiated.
The temperature rise speed is calculated through real-time temperature and historical collected temperature, and when the temperature rise speed is larger than the temperature rise speed threshold, the fact that the real-time temperature rise speed in the vehicle-mounted wireless charger is too high indicates that active heat dissipation is needed.
And the third is that: calculating the temperature rising speed based on the collected real-time temperature and the historical collected temperature, determining a second temperature threshold corresponding to the temperature rising speed, judging whether the collected real-time temperature is greater than the second temperature threshold, and if so, determining that the vehicle-mounted wireless charger needs to be actively cooled.
The heat dissipation controller is internally pre-stored with temperature thresholds corresponding to different temperature rising speeds, and after the temperature rising speed is calculated based on the real-time temperature and the historical collected temperature, the corresponding second temperature threshold is determined according to the current temperature rising speed. If the real-time temperature is larger than the second temperature threshold value, the real-time temperature in the vehicle-mounted wireless charger is too high, and active heat dissipation is needed. The first temperature threshold, the rising speed threshold and the second temperature threshold can be obtained through calibration in practical application, and can also be set according to experience.
Of course, in practical applications, there may be other embodiments in step S202, for example, it may be determined that active heat dissipation is required when the acquired real-time temperature is greater than the first temperature threshold and the temperature rising speed calculated based on the acquired real-time temperature and the historical acquired temperature is greater than the rising speed threshold.
Step S203: and generating an air conditioner refrigeration instruction when the situation that the vehicle-mounted wireless charger needs to be actively radiated is judged.
In a specific implementation manner of the embodiment of the present application, step S203 may include:
s1: and generating a refrigeration starting command when judging that the vehicle-mounted wireless charger needs to be actively radiated.
S2: a temperature rise rate is calculated based on the collected real-time temperature and the historical collected temperature. If the temperature increase rate is calculated in step S202, the temperature increase rate calculated in step S202 may be used.
S3: calculating target air conditioner parameters based on the acquired real-time temperature and the temperature rising speed; the target air conditioner parameters comprise temperature control information and wind speed control information.
The temperature control information includes air conditioner temperature and the wind speed control information includes air conditioner wind speed. Calculating the target air conditioning parameters based on the real-time temperature and the temperature rising speed is a mature technology and is not limited herein. It can be understood that the faster the temperature rise speed, the higher the current temperature value, and the lower the air conditioner temperature and the higher the wind speed.
S4: and generating an air conditioner refrigeration instruction based on the refrigeration starting command and the target air conditioner parameter.
In practical applications, step S203 may also have other embodiments, for example, the air-conditioning temperature and the air-conditioning air speed when the vehicle-mounted wireless charger performs active heat dissipation may be preset, so as to generate an air-conditioning cooling instruction.
Step S204: and the heat dissipation controller sends an air conditioner refrigeration instruction to the vehicle-mounted air conditioner controller through the data transceiver so that the vehicle-mounted air conditioner controller starts a refrigeration mode of the vehicle-mounted air conditioner.
According to the technical characteristics, the present embodiment has the following beneficial effects:
in the embodiment, the vehicle-mounted wireless charger is connected with the vehicle-mounted air conditioner controller, and the air conditioner refrigeration instruction can be generated and sent to the vehicle-mounted air conditioner controller under the condition that the vehicle-mounted wireless charger determines that the vehicle-mounted wireless charger needs to actively dissipate heat, so that the vehicle-mounted air conditioner controller can control the vehicle-mounted air conditioner to start the refrigeration mode. Carry out initiative heat dissipation to on-vehicle wireless charger through on-vehicle air conditioner, compare in the automatic heat dissipation of metal fin, can improve cooling efficiency, and then promote charging efficiency.
According to an embodiment of the present application, a second embodiment of a heat dissipation method for an in-vehicle wireless charger is provided. Referring to fig. 3, the following steps may be included:
step S301: when the mobile terminal is charged by the vehicle-mounted wireless charger, the real-time temperature of the vehicle-mounted wireless charger is acquired through the temperature sensor.
Step S302: whether the vehicle-mounted wireless charger needs to be actively cooled is judged based on the acquired real-time temperature. If necessary, the process proceeds to step S303, otherwise, the process proceeds to step S301.
Step S303: and generating an air conditioner refrigeration instruction when the situation that the vehicle-mounted wireless charger needs to be actively radiated is judged.
Steps S301 to S303 are identical to steps S201 to S203, and are not described herein again.
Step S304: and the heat dissipation controller acquires the current air conditioning parameters of the vehicle-mounted air conditioner from the vehicle-mounted air conditioner controller by using the data transceiver.
Step S305: and the heat dissipation controller judges whether the vehicle-mounted air conditioner is started or not based on the current air conditioner parameters. If not, the process goes to step S306, otherwise, the process goes to step S308.
Step S306: and the heat dissipation controller sends an air conditioner refrigeration instruction to the vehicle-mounted air conditioner controller through the data transceiver so that the vehicle-mounted air conditioner controller starts a refrigeration mode of the vehicle-mounted air conditioner.
Namely, if the current air conditioner parameter represents that the vehicle-mounted air conditioner is not started, the heat dissipation controller sends an air conditioner refrigeration instruction to the vehicle-mounted air conditioner controller through the data transceiver so that the vehicle-mounted air conditioner controller starts a refrigeration mode of the vehicle-mounted air conditioner.
Step S307: the heat dissipation controller controls the switch device to open the air outlet.
If the current air conditioner parameter represents that the vehicle-mounted air conditioner is not started, it is indicated that the current temperature in the vehicle does not reach the refrigeration environment, and therefore the user does not start the vehicle-mounted air conditioner temporarily. In order to guarantee user experience, the vehicle-mounted wireless charger can be opened to the switch device of the corresponding air outlet of the vehicle-mounted wireless charger, so that the vehicle-mounted air conditioner can smoothly output cold air through the air outlet, and active heat dissipation is carried out on the vehicle-mounted wireless charger within the range of the air outlet.
Optionally, in order to guarantee that the user experiences and avoids the user from feeling cold air under the unhealthy condition, other air outlets of the vehicle-mounted air conditioner can be closed in a prompting manner.

Step S310: and if the current air-conditioning parameter enables the air conditioner to output cold air, the heat dissipation controller judges whether the cold air degree corresponding to the current air-conditioning parameter is smaller than the cold air degree corresponding to the target air-conditioning parameter. If so, the process proceeds to step S311, otherwise, the process proceeds to step S312.
And if the current air-conditioning parameter enables the vehicle-mounted air conditioner to output cold air, the vehicle-mounted air conditioner is indicated to be refrigerating, and under the condition, whether the cold air degree corresponding to the current air-conditioning parameter is smaller than the cold air degree corresponding to the target air-conditioning parameter is judged so as to measure that the cold air degree of the air-conditioning parameter is larger.

Step S312: and if the cold air degree corresponding to the current air-conditioning parameter is not less than the cold air degree corresponding to the target air-conditioning parameter, the current air-conditioning parameter is defaulted to be continuously used.
If the cold air degree corresponding to the current air-conditioning parameter is not less than the cold air degree corresponding to the target air-conditioning parameter, the current air-conditioning parameter is more beneficial to cooling, and the user experience is ensured, so that no operation is executed, and the current air-conditioning parameter of the vehicle-mounted air conditioner is continuously used by default.
