Description

  The present invention relates to a technique for effectively using heat that has been discharged into the atmosphere via an automobile.

  In recent years, the energy efficiency of automobiles has improved due to advances in gasoline engine technology and the spread of hybrid vehicles, but as shown schematically in Fig. 4 (a), the energy obtained from fuel is about 40%. Yes, 60% is discharged into the atmosphere as heat.

  In addition, automobiles generally have a shape that has a wide surface in the horizontal direction and travel mainly outdoors, so that they are easily affected by solar radiation as schematically shown in FIG. Furthermore, since the interior of the vehicle is a sealed space surrounded by a glass surface like a greenhouse, heat is accumulated in the body and the vehicle, especially in summer, and the temperature is much higher than the surroundings. If air conditioning is used to make the interior of the vehicle comfortable, heat will be discharged into the atmosphere outside the vehicle.

It is a figure which illustrates typically the heat loss and heat | fever accumulation of the conventional motor vehicle.

  Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration of an automobile exhaust heat utilization system 10 according to the present embodiment. As shown in this figure, the automobile exhaust heat utilization system 10 includes an automobile 100 and a facility 200, and uses the heat accumulated in the automobile 100 in the facility 200 as a basic form. Note that the number of automobiles 100 and the number of facilities 200 constituting the automobile exhaust heat utilization system 10 are arbitrary.

  The automobile 100 includes a power system 110, a heat collector 120, a heat conduction path 130, and an in-vehicle heat exchanger 140. The in-vehicle heat exchanger 140 is connected to each of the power system 110 and the heat collector 120 via the heat conduction path 130.

  The power system 110 is a mechanism for driving the automobile 100 with energy supplied from a fuel, a power source, and the like, and is a block that is originally provided in the automobile 100. The power mechanism of the power system 110 may be any type such as a gasoline engine, a diesel engine, and an electric motor. The power system 110 generates heat by consuming energy when the automobile 100 is traveling.

  The heat collector 120 accommodates a heat medium and collects solar energy received by the automobile 100 as heat. As the heat medium, a fluid having a large heat capacity or latent heat and a large heat transfer coefficient is preferably used, and water, oil, antifreeze, gas, or the like can be used. However, a solid heat medium may be used. The heat collector 120 is disposed at a place where it is easy to receive sunlight, such as the hood, roof, trunk, and interior of the automobile 100 in order to increase the heat collection efficiency. For this reason, it is preferable that the heat collector 120 is a flat housing and has a dark color.

  The heat conduction path 130 is a path through which the heat medium flows, and guides the heat generated in the power system 110 and the heat collected by the heat collector to the in-vehicle heat exchanger 140. The heat conduction path 130 is made of a material that does not corrode with a heat medium. When a solid heat medium is used, the heat conduction path 130 may be formed of the solid.

  The in-vehicle heat exchanger 140 stores one or a plurality of heat storage cartridges 20 and accumulates heat transmitted through the heat conduction path 130 in the heat storage cartridge 20. The heat storage cartridge 20 is detachable. For example, the heat storage cartridge 20 can be configured by housing the latent heat storage material in a heat insulating container provided with a heat inlet / outlet for transferring heat with a heat medium. The transfer of heat with the heat medium can be performed using, for example, heat conduction or heat medium oil.

  The latent heat storage material is a substance that stores heat using heat that enters and exits during phase transition, and erythritol, sodium acetate trihydrate, sodium sulfate decahydrate, and the like can be used. Since these substances do not generate a chemical reaction and are nonflammable, they can be handled safely in the automobile 100. However, a heat storage material other than the latent heat storage material may be accommodated in the heat storage cartridge 20.

  With the configuration described above, the automobile 100 performs processing for accumulating heat generated during traveling and heat obtained by receiving sunlight in the heat storage cartridge 20. Since the heat storage cartridge 20 is detachable and moves together with the automobile 100, the heat storage cartridge 20 stored in the automobile 100 can be easily delivered to a desired place. In this embodiment, it shall deliver to the facility 200 as an example.

  The facility 200 can be a factory, a house, a public facility, a commercial facility, or the like, and includes a stationary heat exchanger 210, a heat utilization system 220, a thermoelectric converter 230, an electricity utilization system 240, a heat collector 250, and a heat conduction path 260. It has. The stationary heat exchanger 210 is connected to each of the heat utilization system 220, the thermoelectric converter 230, and the heat collector 250 via a heat conduction path 260 that is a flow path through which the heat medium flows.

  The stationary heat exchanger 210 stores one or a plurality of heat storage cartridges 20, extracts heat stored in the heat storage cartridge 20, and stores heat in the heat storage cartridge 20. The extracted heat is transmitted to the heat utilization system 220 and the thermoelectric converter 230 via the heat conduction path 260.

  The stationary heat exchanger 210 may be configured to be portable. Moreover, the division | segmentation with the vehicle-mounted heat exchanger 140 and the stationary heat exchanger 210 is convenient, and both can be made into a common structure as a heat exchanger.

  The heat utilization system 220 is a block that uses the heat extracted from the heat storage cartridge 20 by the stationary heat exchanger 210. The heat can be used for various purposes such as air conditioning and hot water supply depending on the form of the facility 200.

  The thermoelectric converter 230 converts the heat extracted from the heat storage cartridge 20 by the stationary heat exchanger 210 into electricity. As the thermoelectric converter 230, a thermoelectric element using the Seepeck effect or the like can be used.

  The electricity utilization system 240 is a block that utilizes electricity converted by the thermoelectric converter 230. Electricity can be used for various purposes such as lighting and home appliances according to the form of the facility 200.

  The heat collector 250 is a block that collects heat generated in the facility 200 using a heat medium. For example, if the facility 200 is a factory, heat can be collected by heating the heat medium by exhaust heat from the factory. The heat collected by the heat collector 250 is transferred to the stationary heat exchanger 210 via the heat conduction path.

  The facility 200 only needs to include either the heat utilization system 220 or the electricity utilization system 240 including the thermoelectric converter 230. Further, the heat collector 250 may not be provided.

  With the above configuration, in the facility 200, the heat extracted from the heat storage cartridge 20 is used as it is or converted into electricity for use. Further, in the facility 200, it is possible to collect exhaust heat using the heat collector 250 and store it in the heat storage cartridge 20. The heat storage cartridge 20 that has accumulated heat can be mounted on the in-vehicle heat exchanger 140 of the automobile 100 and delivered to another facility 200.

  It is desirable to standardize the size, capacity, etc. of the heat storage cartridge 20 in order to provide versatility. The in-vehicle heat exchanger 140 and the stationary heat exchanger 210 have a structure corresponding to a standardized size, capacity, and the like. A plurality of types of size, capacity, etc. may be specified. However, the heat storage cartridge 20 and the in-vehicle heat exchanger 140 have sizes that can be mounted in the vehicle.

  For example, as shown in FIG. 2, the heat storage cartridge 20 is formed in a cylindrical shape of a predetermined size, and the in-vehicle heat exchanger 140 and the stationary exchanger 210 have a shape provided with a storage small chamber in which a plurality of heat storage cartridges 20 can be stored. can do. The in-vehicle heat exchanger 140 and the stationary heat exchange are adjusted so that the number of the heat storage cartridges 20 that can be stored can be adjusted according to the vehicle on which the in-vehicle heat exchanger 140 is mounted, the location of the stationary heat exchanger 210, the characteristics of the facility 200, and the like. It is desirable to allow the vessel 210 to be selected from a plurality of sizes.

  For example, in the in-vehicle heat exchanger 140 mounted on the automobile 100 shown in FIG. 2A, four heat storage cartridges 20 can be stored, and the stationary heat disposed in the facility shown in FIG. In the exchanger 210, eight heat storage cartridges 20 can be stored.

By storing, the heat accumulated in the automobile 100 can be used in the facility 200.

  Further, the heat storage cartridge 20 that has accumulated heat in a certain facility 200 is stored in the in-vehicle heat exchanger 140 of the automobile 100, moved to another facility 200, and stored in the stationary heat exchanger 210 of the destination facility 200. Thus, the heat accumulated in one facility 200 can be used in another facility 200 that lacks energy.

  In addition, by mounting a heat utilization system or a thermoelectric converter in the automobile 100, the heat accumulated in the facility 200 can be used in the automobile 100. It is also possible to store excess heat in the heat storage cartridge 20 and use the heat later.

  As described above, in the automobile exhaust heat utilization system 10 according to the present embodiment, the heat accumulated in the automobile 100 can be used in the facility 200 via the heat storage cartridge 20. Heat can be used effectively through the automobile.
