Description

Technical Field

[0001] This utility model belongs to the field of vehicle air conditioning technology, and in particular relates to a vehicle-mounted solar-powered in-vehicle environment regulation device based on a semiconductor heat pump. Background Technology

[0002] Currently, vehicles are enclosed spaces, resulting in either stale air, excessively high temperatures, or unbearably cold interiors year-round, making them unsuitable for entry. Each time a vehicle is used, the owner must start the car and turn on the air conditioning to regulate the temperature, which takes a long time to reach a comfortable environment. Some high-end vehicles, in an attempt to provide a comfortable environment, constantly consume onboard energy to keep the air conditioning running or turn it on prematurely. This not only wastes energy but also negatively impacts the vehicle's lifespan. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a vehicle-mounted solar-powered in-vehicle environment regulation device based on semiconductor heat pump. It uses solar energy to provide energy and regulates the in-vehicle environment through semiconductor heat pump technology. It can not only meet the needs of regulating the air inside the vehicle, but also regulate the vehicle's ambient temperature as needed.

[0004] To address the above technical problems, this utility model provides an in-vehicle solar-powered vehicle interior environment regulation device based on a semiconductor heat pump, comprising a solar panel and a semiconductor heat pump. The solar panel is connected to a battery, and the battery is connected to the semiconductor heat pump, a micro compressor, an internal fan, and an external fan via an inverter. One end of the micro compressor is connected to the hot end and cold end of the semiconductor heat pump, and the other end is connected to the internal heat exchanger and the external heat exchanger.

[0005] This invention utilizes solar power to provide the necessary power for a semiconductor heat pump. The semiconductor heat pump has high heat exchange efficiency, and at the same time, it achieves air circulation between the inside and outside of the vehicle through internal and external fans. There is no problem of dust accumulation or fresh air being polluted by indoor exhaust. It makes full use of solar energy and does not require the consumption of conventional energy.

[0006] The optimized technical solution of this utility model is as follows: Furthermore, one end of the micro compressor is connected to the positive electrode heat-conducting plate and the negative electrode heat-conducting plate through pipes, and the other end is connected to the internal heat exchanger and the external heat exchanger.

[0007] In the above structure, the positive and negative heat-conducting plates are connected to a micro compressor via pipes. The micro compressor is in turn connected to the internal and external heat exchangers. The micro compressor drives the coolant to flow and deliver it to the internal and external heat exchangers for heat exchange, thus achieving energy transfer. The micro compressor only circulates the coolant and does not need to compress it, requiring relatively little operating energy.

[0008] Furthermore, one side of the semiconductor heat pump is connected to the positive electrode heat-conducting plate via thermally conductive silicone, and the other side is connected to the negative electrode heat-conducting plate via thermally conductive silicone.

[0009] Furthermore, the positive electrode heat-conducting plate and the negative electrode heat-conducting plate are connected by a dense network of pipes, and coolant is disposed within the dense network of pipes.

[0010] Furthermore, both the positive and negative heat-conducting plates are made of copper.

[0011] Furthermore, an insulation plate is provided on the side of the semiconductor heat pump connecting the positive electrode heat-conducting plate and the negative electrode heat-conducting plate.

[0012] Furthermore, the external fan is arranged towards the external heat exchanger, and an external air outlet is provided on the air path of the external fan outside the external heat exchanger, with the opening of the external air outlet facing outwards; the internal fan is arranged towards the internal heat exchanger, with the air outlet of the internal fan facing inwards.

[0013] The above-mentioned heat dissipation structure not only facilitates the auxiliary semiconductor heat pump to dissipate heat and improves the heat dissipation effect of the device, but also regulates the air environment inside the vehicle.

[0014] Furthermore, the battery is connected to the controller via an inverter, and the controller is connected to the semiconductor heat pump, the internal fan, the external fan, and the micro compressor.

[0015] Furthermore, the solar panels are installed at the rear window of the vehicle or the sunroof.

[0016] This invention integrates the solar panel with the rear window glass or sunroof, making installation convenient. By utilizing part of the window, the solar panel is effectively used without compromising vehicle lighting, thus saving installation space.

[0017] The advantages of this utility model are its simple structure, high reliability, and the use of semiconductor heat pump technology, which enables rapid cooling and heating, and has the advantages of energy saving, environmental protection, and no noise. Attached Figure Description

[0021] This embodiment provides an onboard solar-powered vehicle interior environment regulation device based on a semiconductor heat pump, such as... Figure 1 As shown, the system includes a solar panel 12 and a semiconductor heat pump 1. The solar panel 12 is installed at the rear window of the vehicle compartment or the sunroof. The solar panel 12 is connected to a battery 11. The battery 11 is connected to the semiconductor heat pump 1, a micro compressor 8, a controller 9, an internal fan 6, and an external fan 5 via an inverter 10. One end of the micro compressor 8 is connected to the hot and cold ends of the semiconductor heat pump 1, and the other end is connected to the internal heat exchanger 7 and the external heat exchanger 4. The micro compressor 8 adopts a modular multi-chamber design, including a power motor and four independent chambers. The power motor drives the four independent chambers, each chamber structured like an independent water pump. The four independent chambers are divided into two groups, each group containing two independent chambers. One group of chambers pumps the coolant from the heat-conducting plate into the heat exchanger, and the other group of chambers pumps the coolant from the heat exchanger back into the heat-conducting plate, and so on. The specific connection is as follows: the motor output shaft is directly connected to the central crankshaft via a coupling or gear set, converting rotational motion into linear reciprocating motion. The central crankshaft connects to four independent cranks, which are symmetrically distributed with consistent crank radii. Each crank is connected to a piston or diaphragm in one chamber via a connecting rod, enabling a single motor to synchronously drive all four chambers. The crank angles of two chambers in the same group differ by 180°, ensuring that when one chamber is in the discharge stroke, the other is in the suction stroke, thus achieving continuous fluid transport. During compression, the coolant is compressed by the piston in the sealed chamber, reducing its volume and increasing its pressure and temperature before entering the heat exchanger. During reflux, the coolant, cooled by the heat exchanger, is isobarically transported back to the heat transfer plate through another group of chambers, completing the cycle. The micro compressor 8 can also use a Refco SW3H-7500 four-parallel unit or a Hitachi micro compressor BSA274CR-R1AN.

[0022] One side of the semiconductor heat pump 1 is bonded to the positive copper heat-conducting plate 2 using thermally conductive silicone, and the other side is bonded to the negative copper heat-conducting plate 3 using the same silicone. An insulation plate is installed on the side of the semiconductor heat pump 1 connecting the positive and negative heat-conducting plates, ensuring that heat transfer between the two plates is prevented. Furthermore, the positive and negative copper heat-conducting plates 2 and 3 are connected by a relatively dense network of interconnecting pipes containing coolant to allow for coolant flow between them. The semiconductor heat pump 1 utilizes the Peltier effect of semiconductors, where cooling and heating phenomena occur at the two electrodes when current passes through the semiconductor. Switching between the positive and negative electrodes allows for switching between cooling and heating states.

[0023] One end of the micro compressor 8 is connected to the positive copper heat-conducting plate 2 and the negative copper heat-conducting plate 3 via pipes, and the other end is connected to the internal heat exchanger 7 and the external heat exchanger 4.

[0024] An external fan 5 is installed together with an external heat exchanger 4, and the external fan 5 is positioned facing the external heat exchanger 4. An external air vent is located on the outside of the external heat exchanger 4 along the airflow path of the external fan 5, with its opening facing outwards. The external fan 5 blows air towards the external heat exchanger 4, transferring heat from the external heat exchanger 4 to the outside air and dissipating the heat through the external air vent, thus regulating the temperature of one side of the semiconductor heat pump 1. An internal fan 6 is installed together with an internal heat exchanger 7, and the internal fan 6 is positioned facing the internal heat exchanger 7. The air outlet of the internal fan 6 faces inwards, and by blowing air inwards, it transfers heat from the internal heat exchanger 7 to the air inside the vehicle, thus regulating the temperature of the other side of the semiconductor heat pump 1 and also regulating the air inside the vehicle.

[0025] Additionally, the battery 11 is connected to the controller 9 via the inverter 10, and the controller 9 is connected to the semiconductor heat pump 1, the internal fan 6, the external fan 5, and the micro compressor 8. Figure 2As shown, the controller 9 has a knob on its panel with four positions: "Off," "Cooling," "Ventilation," and "Heating." Rotating the knob allows for switching between off, ventilation, cooling, and heating modes for the entire device. The controller 9 is a rotatable switch that adjusts the voltage and reverses the power supply. On one hand, it rationally distributes the current and voltage of the inverter 10 to the semiconductor heat pump 1, the internal fan 6, the external fan 5, and the micro compressor 8. On the other hand, the knob controls the power distribution. When only the semiconductor heat pump 1 is not powered, it is in "Ventilation" mode; when all appliances are not powered, it is in "Off" mode; and when all appliances are powered, "Ventilation" and "Heating" are achieved by reversing the polarity of the power supply. The controller can also be composed of a main control switch that controls the on / off switching and commutation of the basic circuit and a voltage regulation module that controls the fine adjustment of the voltage. Chint LW5D-16 YH3 / 3 or Yaming LW26-20 / 4 can be used as the main control switch, and Yaming LW39-16B extended rheostat or Yurunfa RS25 9-band switch can be used as the voltage regulation module.

[0026] When using this device, turn the knob to the corresponding position. When the entire device needs to be turned off, turn the knob to the off position, and the controller 9 controls the disconnection of the battery 11 from the power supply to the semiconductor heat pump 1, the micro compressor 8, the internal fan 6, and the external fan 5. When ventilation is needed, turn the knob to the ventilation position, and the controller 9 controls the battery 11 to supply power to the internal fan 6 and the external fan 5, which then start, allowing air circulation inside and outside the vehicle. When heating or cooling is needed, turn the knob to the heating or cooling position, and the controller 9 controls the battery 11 to supply power to the semiconductor heat pump 1, the micro compressor 8, the internal fan 6, and the external fan 5. At the same time, the voltage supplied to the semiconductor heat pump 1 can be adjusted by adjusting the knob of the controller, thereby adjusting the required heating or cooling capacity.

[0027] In actual operation, the battery 11 provides a variable operating voltage to the semiconductor heat pump 1 via the controller 9, allowing the two panels of the semiconductor heat pump 1 to become either cold or hot ends as needed. When the device operates in cooling mode, the battery 11 supplies power to the semiconductor heat pump 1 via the controller 9, making the panel with the positive copper heat-conducting plate 2 the cold end. The cold end exchanges heat with the positive copper heat-conducting plate 2, lowering the temperature of the coolant inside the positive copper heat-conducting plate 2. The controller 9 controls the micro compressor 8 to operate, driving the coolant to be delivered to the internal heat exchanger 7. Under the blowing of the internal fan 6, the internal heat exchanger 7 lowers the ambient temperature inside the vehicle. The coolant after heat exchange in the internal heat exchanger 7 is then transported to the micro compressor 8. Driven by the micro compressor 8, the coolant returns to the positive copper heat-conducting plate 2. At this time, the panel on which the negative copper heat-conducting plate 3 is installed becomes the hot end. The hot end exchanges heat with the negative copper heat-conducting plate 3, causing the temperature of the coolant in the negative copper heat-conducting plate 3 to rise. The heated coolant is delivered to the external heat exchanger 4 under the drive of the micro compressor 8. The external heat exchanger 4, under the action of the external fan 5, transfers the heat to the outside of the vehicle. After heat exchange, the coolant in the external heat exchanger 4 returns to the negative copper heat-conducting plate 3 under the drive of the micro compressor 8. Conversely, when the device operates in heating mode, the controller 9 changes the direction of the current supplying the semiconductor heat pump 1, making the panel with the positive copper heat-conducting plate 2 the hot end. The hot end exchanges heat with the positive copper heat-conducting plate 2, increasing the temperature of the coolant inside the positive copper heat-conducting plate 2. The controller 9 controls the micro compressor 8 to work, driving the coolant to be delivered to the internal heat exchanger 7. Under the blowing of the internal fan 6, the internal heat exchanger 7 increases the ambient temperature inside the vehicle. The coolant after heat exchange in the internal heat exchanger 7 is then transported to the micro compressor. Driven by the micro compressor 8, the coolant returns to the positive copper heat-conducting plate 2; at this time, the panel on which the negative copper heat-conducting plate 3 is installed becomes the cold end, and the cold end exchanges heat with the negative copper heat-conducting plate 3, causing the temperature of the coolant in the negative copper heat-conducting plate 3 to decrease. The cooled coolant is delivered to the external heat exchanger 4 under the drive of the micro compressor 8, and the external heat exchanger 4 exchanges heat with the outside air under the action of the external fan 5. The coolant in the external heat exchanger 4, after the heat exchange and heating, returns to the negative copper heat-conducting plate 3 under the drive of the micro compressor 8.

[0028] In addition, the positive copper heat-conducting plate 2 and the negative copper heat-conducting plate 3 are connected by dense interconnecting pipes, which enables the flow of coolant between the positive copper heat-conducting plate 2 and the negative copper heat-conducting plate 3, thereby realizing heat transfer in cooling and heating modes.

[0029] The device of this invention is installed on a vehicle, and there are strict requirements on the external dimensions and installation method of each component, requiring each component to be thin and reliable. Since there are very limited places on a vehicle where solar power generation can be used without affecting the vehicle's appearance design, the energy consumption requirement of this invention is extremely low, while still meeting the energy needs for vehicle interior temperature regulation. Therefore, this invention adopts a separate structural design, which can integrate each component into the overall vehicle design. For example, the solar panel 12 can be integrated with the rear window glass or sunroof, and the battery 11 and inverter 10 can be installed in suitable locations on the vehicle (such as the top and bottom exterior of the vehicle).

[0030] This invention uses semiconductor heat pump technology. Since semiconductor heat pumps have no mechanical movement, their energy conversion efficiency is extremely high and there is virtually no other energy loss. The eight miniature compressors required in the entire design only serve to circulate the coolant and do not need to compress the coolant, so the required operating energy is also very small.

[0031] This invention adopts a distributed structural design, which is beneficial to the overall vehicle design; all moving parts have simple structures and high reliability; the simple structure and minimal number of moving parts greatly reduce energy loss during movement and improve energy utilization; the use of semiconductor heat pump technology ensures fast cooling and heating response; the full utilization of solar energy makes it energy-saving, environmentally friendly, clean, and easy to maintain; the in-vehicle environment regulation device can regulate the interior temperature after the engine is turned off, improving vehicle comfort and saving energy.

[0032] In addition to the embodiments described above, this utility model may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
