Specifically, the step 103 includes the following steps:
when the range extender is in a starting state, the first temperature is smaller than a preset temperature interval, and the second temperature is smaller than a first preset temperature, outputting a first control signal to the heater 4, and adjusting the heating temperature of the heater 4 to the maximum heating temperature;
when the range extender is in a starting state, the first temperature is smaller than the preset temperature interval, and the second temperature is greater than the first preset temperature, outputting a first control signal to the heater 4, and adjusting the heating temperature of the heater 4 to a first preset temperature value;
when the range extender is in a starting state, the first temperature is within the preset temperature range, and the second temperature is lower than the first preset temperature, outputting a first control signal to the heater 4, and adjusting the heating temperature of the heater 4 to a first preset temperature value;
when the range extender is in a starting state, the first temperature is within the preset temperature range, and the second temperature is higher than the first preset temperature, outputting a first control signal to the heater 4, and adjusting the heating temperature of the heater 4 to a second preset temperature value;
when the range extender is in a starting state, the first temperature is higher than the preset temperature range, and the second temperature is lower than the first preset temperature, outputting a first control signal to the heater 4, and adjusting the heating temperature of the heater 4 to a third preset temperature value;
when the range extender is in a starting state, the first temperature is higher than the preset temperature interval, and the second temperature is higher than the first preset temperature, a first control signal is output to the heater 4, and the heating temperature of the heater 4 is adjusted to zero.
In an embodiment of the present invention, the first preset temperature is 40 °, the preset temperature interval includes a second preset temperature and a third preset temperature, the second preset temperature is 20 °, the third preset temperature is a normal operating temperature of the range extender, when the range extender is a fuel cell, the third preset temperature is 65 °, and when the range extender is an engine, the third preset temperature is 95 °.
Specifically, the first preset temperature value is 75% of the maximum heating temperature value, the second preset temperature value is 50% of the maximum heating temperature value, the third preset temperature value is 50% of the maximum heating temperature value, and the fourth preset temperature value is 25% of the maximum heating temperature value, for example, when the maximum heating temperature is 100 °, the first preset temperature value is 75 °, and the second preset temperature value, the third preset temperature value, and the fourth preset temperature value correspond to the above relationships, respectively.
When the first temperature is less than 20 degrees, which indicates that the range extender is in a low-temperature cold start state, in this state, the second temperature is higher than 40 degrees, which cannot be realized only by the waste heat of the range extender, so that the heating temperature of the heater 4 is adjusted to the maximum heating temperature, and the air entering the inside of the shell 1 is heated, and meanwhile, the range extender is also helped to quickly realize warm-up.
When the first temperature is between 20 degrees and the third preset temperature, which indicates that the range extender is entering a normal working state, and when the second temperature is lower than 40 degrees, the heating temperature provided by the heater 4 is reduced to 75 percent of the maximum heating temperature along with the increase of the temperature of the water entering the radiator fin 2 because the water between the circulating pipelines 3 is continuously increased; after the heater 4 is heated for a period of time, the outlet air temperature of the casing 1, i.e., the second temperature, is increased, and when the second temperature is higher than 40 °, the maximum heating temperature of the heater 4 is adjusted to 50% of the maximum heating temperature, so that the second temperature is maintained at about 40 °.
In the present invention, when the range extender is in the activated state, the first temperature is higher than the third preset temperature, and the second temperature is lower than 40 °, the maximum heating temperature of the heater 4 is reduced to 25% of the maximum heating temperature because the amount of heat provided in the radiator fin 2 is increased at this time. When the second temperature rises to 40 ° or more, the heater 4 is turned off, and the air taken into the casing 1 is heated by the residual heat of the range extender.
According to the combination condition of different first temperatures and second temperatures, the heating temperature of the heater 4 is increased or reduced, and the purpose of reducing electric energy while ensuring that the outlet air temperature provided for the passenger compartment meets the conditions is achieved.
Specifically, the step 104 includes:
when the range extender is in a starting state and the first temperature is smaller than a preset temperature interval, inputting a second control signal to the mobile device 5, and adjusting the distance between the radiator fin 2 and the heater 4 to be minimum;
when the range extender is in a starting state and the first temperature is within the preset temperature range, inputting a second control signal to the moving device 5, and adjusting the heater 4 to move towards the direction far away from the radiator fin 2;

When the first temperature is less than 20 °, the range extender can be quickly warmed up by adjusting the distance between the radiator fin 2 and the heater 4 to the minimum in addition to the measure of adjusting the heating temperature of the heater 4 to the maximum heating temperature. The above-mentioned adjustment of the distance between the radiator fin 2 and the heater 4 to the minimum means that the heater 4 is moved to be attached to the radiator fin 2, and the distance between the radiator fin 2 and the heater 4 is reduced, whereby the medium in the radiator fin 2 can be rapidly heated, and rapid warm-up of the range extender is facilitated.
When the first temperature is more than 20 degrees and less than the third preset temperature, the heater 4 is moved away from the radiator fin 2, so that the medium in the radiator fin 2 cannot be heated quickly; the temperature of the range extender can not be increased in a short time, and the range extender is prevented from being damaged; meanwhile, in the process, the heating temperature of the heater 4 is correspondingly reduced, and reasonable utilization of electric energy is realized.
When the first temperature is higher than the third preset temperature and the second temperature is lower than 40 degrees, the heater 4 is required to heat the air in order to raise the second temperature, the heater 4 is moved to a position farthest from the radiator fin 2, and the heating temperature of the heater is reduced to 25% of the maximum heating temperature, so that the situation that the heater 4 heats the radiator fin 2 can be reduced to the greatest extent, and the situation that the range extender is damaged due to the fact that the temperature in the radiator fin 2 is further raised is prevented; in addition, when the second temperature is greater than 40 °, since the heater 4 is already turned off, it is not necessary to adjust the distance between the heater 4 and the radiator fin 2.
Specifically, the step 106 is specifically:
when the range extender is in a starting state, the first temperature and the third temperature are both greater than a preset temperature range, a third control signal is input into the circulation pipeline 3, and the medium in the circulation pipeline 3 is controlled to enter a heat dissipation circulation pipeline.
When first temperature and third temperature all are greater than the third and predetermine the temperature, in order to avoid increasing the journey ware and damaged because of too high temperature, get into the medium rapid cooling that the medium among the circulation pipeline helped the circulation pipeline that dispels the heat through the medium in the control flow pipeline 3, also help increasing the temperature of the medium among the journey ware heat radiation structure and reduce fast promptly, and then realize helping increasing the journey ware rapid cooling, reach normal operating temperature.
According to the heat exchange control method for the passenger compartment of the automobile, the heating temperature of the heater 4 and the temperature between the heater 4 and the radiator fin 2 are adjusted according to the change conditions of the first temperature, the second temperature and the third temperature, so that the waste heat of the range extender is utilized, meanwhile, the control of electric energy consumption can be reasonably realized, the purpose of saving resources is realized, and the operation cost is reduced.
