DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of a mobile power supply vehicle according to the present invention will be described in detail below. FIG. 1 is a block diagram showing an example of a configuration of a power generation facility and a hot water supply facility installed inside a container 1 mounted on a self-propelled vehicle of a mobile power supply vehicle according to a first embodiment of the present invention. In FIG. 1, a power generating facility including a generator 3 for supplying power to an external load L and a generator driving engine 2 which is directly connected to the generator 3 and drives the generator 3 is installed inside the container 1. I have. As the generator driving engine 2, a water-cooled diesel engine or the like is used. The generator driving engine 2 is provided with a first heat exchanger 4 for cooling that absorbs heat from the main body of the generator driving engine 2 and conducts the heat to a heat medium (cooling water). In the heat absorbing portion 4a of the first heat exchanger 4, a bypass passage 4b is provided in parallel via a three-way valve 5 having a thermostat.

From the generator driving engine 2, an exhaust gas heat exchanger 6 as a second heat exchanger and a muffler 7
And an exhaust pipe 8 for discharging exhaust gas from the generator driving engine 2 to the outside of the container 1 extends outside the container 1. The exhaust gas heat exchanger 6 recovers the heat of the exhaust gas discharged from the generator driving engine 2 by the heat absorbing unit 6a. The heat absorbing section 6a is connected in series with the heat absorbing section 4a via the three-way valve 5.

In the series circuit of the heat absorbing portion 4a of the first heat exchanger 4 and the heat absorbing portion 6a of the exhaust gas heat exchanger 6 as the second heat exchanger, a third heat The heat radiating portion 10a of the heat radiator 10 as a heat exchanger and the heat radiating portion 11a of the fourth heat exchanger 11 are connected in parallel. Wind is blown to the heat radiating section 10 a to the heat radiating section 10 so that the heat radiating section 10
An electric cooling fan 10b is provided for forcibly releasing heat from a. The heat radiating portion 11 a of the fourth heat exchanger 11 is disposed in the water storage tank 12. A water supply pipe 13 connected to a water pipe is connected to a lower side wall portion of the water storage tank 12, and a hot water supply pipe 1 for supplying hot water heated by the heat radiating portion 11a in the water storage tank is connected to a lower side wall portion.
4 are connected.

In FIG. 1, when the generator driving engine 2 is started, the generator 3 directly connected to the generator driving engine 2 starts generating operation. Electric power generated from the generator 3 is supplied to a load L provided outside. Immediately after the start of the generator driving engine 2 or when the load L is a light load and the temperature of the generator driving engine 2 is low, heat is passed through the bypass passage 4b to prevent the generator driving engine 2 from being overcooled. The thermostated three-way valve 5 is switched so that the medium circulates.

The power generation operation of the generator 3 is continued, the temperature of the generator driving engine 2 gradually increases, and the bypass passage 4
The temperature of the cooling water circulating between b and the heat absorbing section 4a also increases. When the temperature of the cooling water reaches a predetermined temperature, the thermostat provided in the three-way valve 5 is operated, and the cooling water starts flowing from the heat absorbing portion 4a toward the heat absorbing portion 6a. Thereafter, the cooling water circulating in the generator driving engine 2 starts flowing out of the generator driving engine 2. The cooling water flowing out of the generator driving engine 2 recovers the heat of the exhaust gas when passing through the heat absorbing portion 6b of the exhaust gas heat exchanger 6, and becomes higher in temperature. The cooling water that has passed through the exhaust gas heat exchanger 6 flows into the heat releasing portion 11a of the heat exchanger 11 through the three-way valve 9, and the heat of the high-temperature cooling water is radiated into the water storage tank 12 to be released. Heating inside starts. The cooling water whose temperature has decreased due to the heat radiation returns to the generator driving engine 2. The water in the water storage tank 12 is heated by heat radiated from the heat radiating portion 11a of the heat exchanger 11, and becomes hot water of a predetermined temperature. When the temperature of the water in the water storage tank 12 becomes equal to or higher than a predetermined temperature, the three-way valve 9 is switched and flows into the heat radiator 10 a side of the heat radiator 10. The heat of the cooling water flowing into the heat radiator 10 is released from the radiator 10a to the outside air. The radiator 10a is a cooling electric fan 1 forcibly rotated by an electric motor.

When installing two or more water storage tanks, each water storage tank is connected in series via a water storage tank connection pipe.

As described above, in addition to the electric power generated by the power generation operation of the generator 3, a cogeneration system can be constructed in a mobile power supply vehicle by providing a hot water supply facility for boiling hot water with heat generated by the power generation operation. Thus, the fuel use efficiency can be improved.

Is taken into the heat exchanger 211 and heated. The heated water is supplied from the supply pipe 214 to the outside of the container 201. Since the outer wall of the container 201 is covered with water, it plays a role of a soundproof wall against noise generated during the power generation process. In addition, a solar water heater may be installed on the outer wall surface of the container 201 to supply hot water together with hot water supply equipment inside the container 201. In this case, the solar water heater is installed on the ceiling of the container 201 or the like, and water is introduced into the solar water heater from the water supply pipe 213 on the wall panel of the container 201 or a water supply pipe provided at a predetermined location of the solar water heater.
