Description

[Detailed Description of the Invention] This invention relates to an improvement of a rapid heating device for automobiles.

Conventionally, there has been a known rapid heating system for automobiles that uses a generating body that generates heat when energized to obtain warm air until the engine cooling water temperature rises. The problem was that it required several batteries, making it unsuitable for use in automobiles.

This proposal addresses the above-mentioned problems, and includes a tank, a reactor equipped with a substance that chemically reacts with the substance in the tank and generates heat, and a reactor that heats the reactor to decompose each of the above substances. a heating means; a circulation device that circulates the substance on the tank side between the tank and the reactor; and a circulation device that circulates the substance on the tank side to the reactor when the engine cooling water temperature is below a predetermined temperature. and a control device that controls the reactor heating means and the circulation device so that when the temperature of the cooling water reaches a predetermined temperature or higher, the reactor is heated and the substance in the tank is returned to the tank. The object of the present invention is to provide an improved rapid heating device for a vehicle that does not require a large-capacity battery.

The rapid heating system for automobiles of the present invention is configured as described above, and when a passenger starts the engine and then turns on the heater switch, if the engine cooling water temperature is lower than a predetermined temperature, the control device turns on the circulation system. The substance in the tank is sent into the reactor under controlled conditions, causing a chemical reaction with the substance in the reactor to generate heat.

At this time, air is blown around the reactor from a blower or the like, so warm air is instantaneously obtained and sent into the interior of the car, where it is used for heating, defrosting windows, etc.

On the other hand, the engine cooling water temperature increases over time.

When the temperature of this cooling water becomes higher than a predetermined temperature, the control device operates the reactor heating means to heat the reactor and decompose the above substances, and at the same time controls the circulation device to increase the temperature of the reactor. The material on the tank side that has been separated from the material is returned to the tank.

Therefore, a large capacity battery is not required during heating until the engine cooling water temperature rises.

Next, the rapid heating system for automobiles according to the present invention will be explained with reference to an embodiment shown in FIG.
The hot air is circulated between the hot air and the heat exchanger 3, and the hot air obtained by driving the blower 5 is sent into the vehicle interior.

Next, the operation of the above-mentioned rapid heating device for automobiles will be explained.

Passenger or engine I+&O operation: □'s two-way switch 2
0, the temperature of the engine cooling water flowing through the engine piping 41 is detected by the water temperature sensor 151, and if the engine cooling water temperature is lower than the local temperature, valves 16 and 17 are missing. Open in the direction of the mark) At the same time as the hole □, the hole is opened -1
(At the start of one operation, hydrogen in the tank 6 is sent into the reactor 7 via the pipe 8 → compressor 10 → pipe 9.

At this time, the inside of the reactor 7 is on the upper right side of the FeTi line in FIG. 4, and iron titanide combines with hydrogen to generate heat at about 4 atm (see A).

On the other hand, blower 19. is being driven, and when the air from the blower 19b) passes around the reactor 7', it is heated for 1 h.
The hot air is then sent into the car and used for heating, defrosting windows, etc.

The cooling water temperature of the engine 1 increases over time.

If this cooling water temperature becomes higher than a predetermined temperature, valve 1
6 and 17 are opened in the direction of the dashed arrow at the same time, the valve 18
is opened, the exhaust gas in the exhaust pipe 13 also flows into the pipe 14, heating the inside of the reactor 7, and the opening is located lower left than the FeTi line in Fig. 4, where a hydrogen decomposition reaction takes place. , hydrogen is returned to the tank 6 via the pipe 9 → valve 16 → pipe 11 → compressor 10 → pipe 12 → valve 17 → pipe 8.

Further, due to the above action, the pressure inside the reactor 7 decreases and the temperature increases (see B to C), so that the decomposition reaction of hydrogen is further promoted.

When the pressure inside the tank 6 reaches a predetermined pressure, the pressure sensor 21 closes the valves 16, 17, and 18, and at the same time, the compressor 10 stops.

In this state, the temperature of the cooling water of the engine 1 has risen sufficiently, and from then on, hot air will be obtained by the existing heater system 2.
