Description

Technical Field

[0001] The utility model belongs to the technical field of automobile electronics, and in particular relates to an energy conversion device, a vehicle cooling system and a vehicle. Background Art

[0002] The cooling system's main job is to dissipate heat into the air to prevent the engine from overheating, but it has other important functions as well. The engine in your car runs best when it's reasonably hot. If the engine gets cold, it wears out its components faster, making the engine less efficient and producing more pollutants. So another important function of the cooling system is to get the engine warm as quickly as possible, and keep it at a constant temperature.

[0003] The cooling system of a liquid-cooled car circulates liquid through pipes and passages in the engine or motor. When the liquid flows through the hot engine, it absorbs heat, thereby reducing the temperature of the engine. After the liquid flows through the engine, it flows to the heat exchanger or radiator, and the heat in the liquid is dissipated into the air through the heat exchanger. For the car, the utilization efficiency is low and the heat energy cannot be converted into electrical energy for the car to use. Utility Model Content

The described implementation is a part of the implementation of the utility model, not all of the implementations.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] Please refer to the attached Figure 1 The utility model provides an energy conversion device 110, including a water collector 17, a first generator, and an energy storage device. The water collector 17 has a water inlet pipe and a hot water pipe 5. The water inlet pipe is connected to the heat exchanger 120 of the vehicle, and the hot water pipe 5 is connected to the water tank 130 of the vehicle. The water collector 17 is connected to the vehicle heat exchanger 120 to obtain hot water, and the hot water can be stored in the water collector 17 for heat exchange by the first generator. The first generator includes a heat collection module 16 and a power generation module. The heat collection module 16 is connected to the water collector 17, and the power generation module is connected to the heat collection module 16 to convert the heat energy of the heat collection module 16 into electrical energy. The heat of the water collector 17 is obtained by the heat collection module 16 of the first generator, and the heat energy is converted into electrical energy by the power generation module of the first generator. The energy storage device is electrically connected to the power generation module. The energy storage device is used to store the electrical energy generated by the power generation module. The energy storage device can be a storage battery 11 or an electrical device.

[0031] The energy conversion device 110 provided by the utility model is provided with a water collector 17 and a first generator, wherein the first generator has a heat collection module 16 and a power generation module; the heat of the water collector 17 is obtained by the heat collection module 16 of the first generator, and the heat energy is converted into electric energy by the power generation module of the first generator, and the energy is stored by the energy storage device. The heat energy generated by the automobile is converted into electric energy by using the principle of thermoelectric effect, and transmitted to the automobile for use, so as to achieve energy recycling, realize low carbon, energy saving and emission reduction, and has a wide range of application scenarios.

[0032] In some implementations, the heat collection module 16 and the power generation module are arranged in the housing of the first generator; the power generation module includes a hot electrode 13, a cold electrode 15, an electrical insulation plate 12, and a dielectric layer 14. The insulation plate is fixed on the inner wall of the housing, the hot electrode 13 is fixed on the electrical insulation plate 12, and the cold electrode 15 is connected to the hot electrode 13 through one end of the dielectric layer 14 and the other end extends into the heat collection module 16. The cold electrode 15 includes a plurality of P-type thermocouple arms and a plurality of N-type thermocouple arms, and the P-type thermocouple arms and the N-type thermocouple arms are arranged alternately. In this embodiment, the cold electrode extends into the collector, and a potential difference is formed by the temperature difference between the P-type thermocouple arm and the N-type thermocouple arm, thereby generating a current, which passes through the dielectric layer 14 to reach the hot electrode 13, and then outputs electrical energy to the energy storage device through the hot electrode 13. Among them, the cold electrode can be an alloy material such as SnSe, ZnSb, PbTe, GeTe, SiGe, etc.; the main carriers of the P-type thermocouple arm are holes; the main carriers of the N-type thermocouple arm are electrons; the dielectric layer can be an electrolyte or other conductive medium. The first generator processes the hot water output by the heat exchanger 120 through the thermoelectric effect to convert thermal energy into electrical energy. Specifically, the thermoelectric effect is a direct conversion of voltage generated by temperature difference. When there is a temperature difference between the two ends of the P-type thermocouple arm and the N-type thermocouple arm, a voltage will be generated, and when a voltage is applied to it, a temperature difference will also be generated. This effect can be used to generate electrical energy, measure temperature, and cool or heat objects. Different metal conductors have different free electron densities. When two different metal conductors contact each other, the electrons on the contact surface will diffuse to eliminate the difference in electron density. The diffusion rate of electrons is proportional to the temperature of the contact area, so as long as the temperature difference between the two metals is maintained, the electrons can continue to diffuse and form a stable voltage at the other two ends of the two metals. The electric energy generated by the second generator is stored in the energy storage device.

[0033] In some implementations, the water inlet pipe is provided with a first valve 1 and a safety valve 2. The first valve 1 can be sealed and set inside the water inlet pipe, and the safety valve 2 is connected and set at the inner wall of the water inlet pipe. In this embodiment, the water inlet amount and water flow rate of the water collector 17 can be controlled by the first valve 1, so that the hot water generated by the heat exchanger 120 can fully convert thermal energy into electrical energy under the action of the first generator. In addition, a self-induction heating plate 3 can be set in the water collector 17, and the self-induction heating plate 3 is set adjacent to the water inlet pipe, so that the water entering the water inlet pipe is heated by the self-induction heating plate 3. The water inlet pipe is further heated to improve the energy conversion efficiency of the device. The self-induction heating plate 3 can be a carbon fiber plate or a metal mesh composite plate.

[0034] In some implementations, a condenser 8 is further included, the water inlet of the condenser 8 is connected to the hot water pipe 5, and the water outlet of the condenser 8 is connected to the water tank 130 of the vehicle through the water outlet pipe 9. The water inlet of the condenser 8 is provided with a temperature sensor 7. In this embodiment, the condenser 8 is used to convert the hot water generated by the heat exchanger 120 into cold water that can be normally used by the vehicle cooling system 100, and output the cold water to the water tank 130 for storage.

[0035] In some implementations, the energy storage device includes an energy storage battery 11 and an electric energy control module 10. The energy storage battery 11 is connected to the first generator or the second generator to obtain electric energy, and the energy storage battery 11 is connected to the electric equipment of the vehicle through the electric energy control module 10 to output electric energy. In this embodiment, the electric energy of the energy storage battery 11 is output to each electric equipment of the vehicle for power supply through the electric energy control module 10, thereby improving the utilization rate of electric energy and reducing the energy consumption of the vehicle.
