Example one
Fig. 1 is a schematic circuit structure diagram of a vehicle urea heating system according to an embodiment of the present invention, and fig. 2 is a schematic mechanical structure diagram of a vehicle urea heating system according to an embodiment of the present invention. The direction of the arrows in fig. 1 is the direction of flow of the gas. As shown in fig. 1 and fig. 2, the urea heating system for a vehicle according to the present embodiment includes: a supercharger 11, a first valve 12, a urea tank 14, a urea temperature sensor 15, and an electronic control unit ECU 16.
The ECU16 is in communication with the first valve 12 and the urea temperature sensor 15, respectively.
Wherein, the output of booster 11 passes through heating pipeline 13 to be connected with urea case 14's input, and one side that is close to booster 11 on the heating pipeline 13 sets up first valve 12, and heating pipeline 13 extends to and extends out through urea case 14's output behind the urea solution of urea case 14, and urea temperature sensor 15 contacts with the urea solution of urea case 14.
In this embodiment, the urea temperature sensor 15 is configured to collect the temperature of the urea solution. And the ECU16 is configured to control the first valve 12 to open if it is determined that the temperature of the urea solution is equal to the preset crystallization critical temperature, so that the first high-temperature gas output from the heating pipeline 13 after the pressure of the pressure booster 11 heats the urea solution through the heating pipeline 13.
Specifically, in the present embodiment, the ECU16 is also referred to as a "vehicle computer" or a "vehicle-mounted computer", and is composed of a large-scale integrated circuit such as a microprocessor, a memory, an input/output interface, an analog-to-digital converter, a driver, and a shaper. The control system is used for controlling the urea heating system for the vehicle.
In the present embodiment, the supercharger 11 may be a turbocharger 11, or may be another type of supercharger 11. The supercharger 11 compresses the gas before supplying the gas into the cylinder to increase the density of the gas, and in the process of increasing the density of the gas, the temperature of the gas is increased, so that the gas output from the output end of the supercharger 11 is high-temperature gas.
Alternatively, in this embodiment, the gas may be exhaust gas discharged from an internal combustion engine, and since the temperature of the exhaust gas discharged from the internal combustion engine is high, the temperature increase rate of the exhaust gas is increased by the increase of the supercharger 11. The temperature of the gas at the output of the supercharger 11 can be rapidly raised by supercharging the exhaust gas discharged from the internal combustion engine once the vehicle has started.
In this embodiment, the first valve 12 may be a solenoid valve or other types of electrically controlled valves, which is not limited in this embodiment.

To increase the contact area of the heating pipe 13 with the urea solution. In order to further increase the contact area between the heating pipe 13 and the urea solution, optionally, the heating pipe may be led out along the output end of the urea tank 14 after being wound in the urea solution in the urea tank 14.
In this embodiment, the urea temperature sensor 15 is used to collect the temperature of the urea solution, and specifically may be disposed on the inner wall of the urea tank 14 or at the bottom of the urea tank 14, or disposed in the urea solution through the heating pipeline 13, or disposed at a position such as a liquid level surface of the urea solution.
Specifically, in the present embodiment, when the vehicle urea heating system is applied, the urea temperature sensor 15 first collects the temperature of the urea solution, and may periodically or in real time send the temperature of the urea solution to the ECU 16. The ECU16 detects whether the temperature of the urea solution is equal to a preset crystallization critical temperature, and if so, controls the first valve 12 to open, so that the first high-temperature gas output from the heating pipeline 13 after the supercharger 11 is pressurized flows into the heating pipeline 13 in the urea tank 14 and is exhausted from the heating pipeline 13 at the output end of the urea tank 14 to form the cooling gas. When the first high-temperature gas flows through the heating pipeline 13 in the urea box 14, the urea solution can be heated, and after the urea solution is heated, the temperature of the urea solution can be increased, so that the temperature of the urea solution reaches the preset normal temperature. After the ECU16 detects that the urea solution reaches the predetermined normal temperature, the first valve 12 may be controlled to close to stop heating the urea solution.
The high-temperature gas output from the heating duct 13 is the first high-temperature gas. The temperature of the first high-temperature gas may be 55 ℃ or higher.
In this embodiment, the predetermined crystallization critical temperature is a temperature that is greater than the urea crystallization temperature and has a smaller difference from the urea crystallization temperature. The crystallization temperature of urea is-11 ℃, and the preset crystallization critical temperature can be-5 ℃ or-6 ℃, which is not limited in this embodiment.
In this embodiment, the predetermined normal temperature may be 5 ℃, 6 ℃, or other suitable values.

As the vehicle is started, the supercharger 11 can pressurize the gas, the gas temperature can be quickly increased to a high-temperature state, and the urea solution is heated, so that the urea heating speed is greatly increased. Therefore, when the vehicle is in a low-temperature or cold state for heating, the urea can be in a solution state, and the effect of reducing emission of the whole vehicle is achieved. And the urea is not heated by engine cooling heat, so that the power consumption of a 111 water pump of the engine can be reduced, and the dynamic property and the economical efficiency of the whole vehicle are improved.

Specifically, in the present embodiment, the main pipe 17 is first connected to the output side of the supercharger 11, and then the main pipe 17 is connected to the input side of the intercooler 18, and the heating pipe 13 is branched off from the main pipe 17 by the first valve 12. After the high-temperature gas is output from the output end of the supercharger 11, if the first valve 12 is in the open state, a part of the high-temperature gas reaches the intercooler 18, and the intercooler 18 cools the high-temperature gas to obtain the first cooling gas. A part of the high-temperature gas enters the heating pipeline 13 in the urea tank 14 through the heating pipeline 13, heats the urea solution, and outputs the second cooling gas from the heating pipeline 13.

And the ECU16 is further configured to control the second valve 110 to open when the temperature of the urea solution is determined to be equal to the predetermined crystallization critical temperature, so that the second cooling gas heated by the urea solution enters the cooling pipeline 19 and joins with the first cooling gas to form a third cooling gas.
And the ECU16 is further configured to control the first valve 12 and the second valve 110 to close if it is determined that the temperature of the urea solution is equal to the preset normal temperature.
