In one embodiment, as shown in fig. 2, the vehicle warm-up system further includes an engine water temperature sensor 201 connected to the controller 10, the engine water temperature sensor 201 being configured to detect a water temperature in the engine water tank 20 and output engine water temperature information; a first valve component 301 connected to the controller 10 is arranged on the first closed-loop pipeline, and a second valve component 302 connected to the controller 10 is arranged on the second closed-loop pipeline; the controller 10 is further configured to control the second valve assembly 302 to be turned on and the first valve assembly 301 to be turned off when the engine water temperature information is not higher than a preset first threshold; when the engine water temperature information is higher than the first threshold value, the first valve assembly 301 and the second valve assembly 302 are controlled to be conducted.
The first valve component 301 may comprise one or more valves, and the second valve component 302 may also comprise one or more valves. When the first closed-loop pipeline and the second closed-loop pipeline do not have an overlapped part, the first valve component 301 and the second valve component 302 may be configured to be independent of each other, in which case the first valve component 301 may be composed of only a single valve, and the opening and closing of the first closed-loop pipeline may be controlled independently by the opening and closing of the first valve component 301, and the second valve component 302 may also be composed of only a single valve, and the opening and closing of the second closed-loop pipeline may be controlled independently by the opening and closing of the second valve component 302; when the first closed loop pipeline and the second closed loop pipeline have an overlapped part, there may be a case that the first valve assembly 301 and the second valve assembly 302 are related to each other, for example, as shown in fig. 3, the second valve assembly 302 in the second closed loop pipeline includes a solenoid valve I and a solenoid valve II, the first valve assembly 301 in the first closed loop pipeline includes a solenoid valve I and a conducting valve, when the solenoid valve I and the conducting valve are both conducting, the first valve assembly 301 is conducting, when any one of the solenoid valve I and the conducting valve is cut off, the first valve assembly 301 is cut off, when both the solenoid valve I and the solenoid valve are conducting, the second valve assembly 302 is conducting, and when any one of the solenoid valve I and the solenoid valve is cut off, the second valve assembly 302 is cut off. Specifically, when the engine water temperature information is higher than a first threshold value, the preheating phase of the engine is completed; at this time, the first valve component 301 and the second valve component 302 are controlled to be conducted, so that the heat transferred by the heating device 30 can be simultaneously transferred to the engine and the preheating device 40, and the synchronous preheating of the engine and the environment in the vehicle is realized.

The purpose of controlling the radiator 410 to convey the heat emitted from the first closed-loop pipeline into the vehicle according to the temperature information in the vehicle is as follows: the controller 10 controls the heat dissipation energy of the heat sink 410, so that the temperature of the environment in the vehicle falls into a suitable temperature range, and the experience of passengers is not reduced or heat loss is not caused due to overhigh or overlow temperature.
In one embodiment, the controller 10 is further configured to control the radiator 410 to deliver the heat emitted from the first closed-loop pipe to the vehicle according to the vehicle interior temperature information, and includes: when the temperature information in the vehicle exceeds the upper limit of the preset temperature interval, the controller 10 controls the preheating device 40 to work at a first heat dissipation power; when the temperature information in the vehicle is lower than the lower limit of the temperature range, the controller 10 controls the preheating device 40 to work at a second heat dissipation power; the second heat dissipation power is larger than the first heat dissipation power. For example, the preset temperature interval is [15,20], and when the temperature information in the vehicle is lower than 15 ℃, the radiator 410 is controlled to radiate heat with high power at a high gear, so that the temperature in the vehicle is rapidly increased; when the temperature information in the vehicle is higher than 20 ℃, the radiator 410 is controlled to radiate heat with low power at a low gear, so that the ambient temperature in the vehicle is kept stable.
When the engine works, 30% -45% of energy is emitted into air in a heat radiation mode, and if the energy is secondarily utilized, the cost can be saved, and the environment is protected and the emission is reduced.
