Detailed Implementation

[0019] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0020] like Figure 1 , Figure 2 As shown in the figure, an embodiment of this utility model provides a vehicle-mounted dual-purpose cooling and heating temperature control box, including a box body 1 and a box cover 2 that can be sealed to it. Inside the box body 1, a cooling box 3 and a heating box 4 that can keep the temperature are arranged side by side. A partition 5 is provided between the cooling box 3 and the heating box 4. Cooling and heating modules are provided at the bottom of the cooling box 3 and the heating box 4. The cooling and heating modules include a first semiconductor and a second semiconductor 7. The cold end of the first semiconductor 6 at the bottom of the cooling box 3 is facing upward and the hot end is facing downward. The hot end of the second semiconductor 7 at the bottom of the heating box 4 is facing upward and the cold end is facing downward. A heat sink is provided at the bottom of the cooling box 3. A power supply, a controller and a control panel 37 are provided on the side wall of the box body 1. The cooling and heating modules and the heat sink are connected to the power supply and the controller. The control panel 37 is connected to the controller. The cooling and heating modules and the heat sink can be easily controlled by the switch buttons on the control panel. In this solution, the cooling box 3 and the heating box 4 are designed to be isolated to avoid cross-contamination between cold and heat, and to ensure that the refrigeration and heating functions do not interfere with each other. Users can place different foods in the cooling box 3 or the heating box 4 for separate storage, which can meet the diverse food storage needs and improve the convenience and practicality of use.

[0021] Working principle as follows Figure 4As shown, the first semiconductor 6 and the second semiconductor 7 are connected in parallel to a circuit consisting of a power supply and a heat sink. The Peltier effect is used to achieve cooling and heating after power is applied. The first semiconductor 6 and the second semiconductor 7 are large thermocouples composed of multiple P-type and N-type semiconductors. When current flows through them, heat migrates from one end to the other; the reverse current enables reversibility, thus completing the cooling / heating process.

[0022] In practical implementation, the temperature of the cooling box 3 and the heating box 4 is controlled by a temperature controller 19. The temperature controller uses a PID control system to precisely control the temperature, which is existing technology, and a PID temperature controller can be purchased externally during manufacturing. During manufacturing, the first semiconductor 6 and the second semiconductor 7 can use TEC1-12703 semiconductor cooling chips, which have a rated voltage of 12V and a rated current of 8A. Different semiconductors can also be selected according to actual needs.

[0023] In specific embodiments of this utility model, such as Figure 2 As shown, a heat storage box 8 is provided below the refrigeration box 3 to recover the heat from the bottom hot end of the first semiconductor 6 above; a cold storage box 9 is provided below the heating box 4 to recover the cold energy from the bottom cold end of the second semiconductor 7 above; the heat storage box 8 and the cold storage box 9 are connected by a heat-conducting plate 17 to achieve the neutralization of excess cold and heat.

[0024] Further optimize the above structure, such as Figure 3 As shown, both the cooling box 3 and the heating box 4 are equipped with heat pipe arrays 10 at their bottoms. Thermal grease 11 is also located below the heat pipe array 10 at the bottom of the cooling box 3. The heat storage box 8 is positioned below the thermal grease 11, and the cold storage box 9 is positioned below the heat pipe array 10. The thermal conductivity of the heat pipe array 10 is 100-1000 times that of pure copper, with a single pipe weighing 20-50g (3-5mm in diameter), and the total weight being more than 70% lighter than a copper block. Driven by natural temperature difference, the parallel connection of multiple pipes ensures a surface temperature difference of <1℃, achieving efficient and uniform temperature control. The use of heat pipe arrays combines the advantages of thermal conductivity, lightweight (70% weight reduction), and zero energy consumption, making it particularly suitable for the efficient and energy-saving requirements of cooling and heating modules. The heat generated by the first semiconductor hot end at the bottom of the cooling box 3 is evenly distributed and partially introduced into the heat storage box 8 by using the heat pipe array 10 and thermal grease 11. The cold energy generated by the second cooling chip 7 at the bottom of the heating box 4 is evenly distributed and partially introduced into the cold storage box 9 by using the heat pipe array 10.

[0025] like Figure 2As shown, in specific manufacturing, the outer shell 12 of the box body 1 is made of rigid polyurethane foam. The inner walls of the cooling box 3 and the heating box 4 are both made of PCM aluminum plate 13. The three side walls of the cooling box 3, from the inside to the outside, are PCM aluminum plate 13, recycled aluminum plate 14, vacuum insulation board 15 and outer shell 12, which are bonded and fixed with adhesives. The three side walls of the heating box 4, from the inside to the outside, are PCM aluminum plate 13, recycled aluminum plate 14, polyurethane foam board 16 and outer shell 12, which are bonded and fixed with adhesives. The partition 5, from the cooling box 3 to the heating box 4, is PCM aluminum plate 13, recycled aluminum plate 14, vacuum insulation board 15 and polyurethane foam board 16 in sequence. The recycled aluminum plate 14 and PCM aluminum plate 13 are bonded and fixed with adhesive. The bottom of the cooling box 3, from top to bottom, consists of PCM aluminum plate 13, recycled aluminum plate 14, heat pipe array 10, and thermally conductive silicone grease 11, all bonded and fixed with adhesive. The bottom of the heating box 4, from top to bottom, consists of PCM aluminum plate 13, recycled aluminum plate 14, and heat pipe array 10, all bonded and fixed with adhesive. The recycled aluminum plate 14 at the bottom of the cooling box 3 is connected to the heat storage box 8 via a thermally conductive aluminum plate 18, used to transfer heat from the heat storage box to the heating box 4. The recycled aluminum plate 14 at the bottom of the heating box 4 is connected to the cold storage box 9 via a thermally conductive aluminum plate 18, used to transfer the cold energy from the cold storage box 9 to the cooling box 3. Thermally conductive silicone grease or glass glue can be used as the adhesive, ensuring that the side walls of the cooling box 3 and the heating box 4 are connected as a single unit.

[0026] Vacuum insulation board 15 and polyurethane foam board 16 can be used to separate the heating box 4 and the cooling box 3, ensuring functional independence. Thermal grease 11 and heat pipe array 10 transfer heat to the heat storage box 8 and cold storage box 9 respectively, effectively achieving heat dissipation and thermal compensation. The corrugated recycled aluminum plate 14 effectively transfers the cold and heat generated by the first semiconductor 6 and the second semiconductor 7 to the cooling box 3 and the heating box 4, and then the inner liner of the PCM aluminum plate 13 ensures that the energy is evenly distributed within the cooling box 3 and the heating box 4. The corrugated recycled aluminum plate not only increases the heat dissipation area but also has the advantages of being environmentally friendly, lightweight, high-strength, having good thermal conductivity, and low cost.

[0027] The vacuum insulation panel 15 inside the side wall of the cooling box 3 has an ultra-low thermal conductivity, providing excellent insulation. It is also ultra-thin and lightweight, allowing it to be embedded in confined spaces. Its application inside the side wall of the cooling box 3 reduces cold air leakage, is environmentally friendly and energy-saving, and demonstrates significant energy-saving and consumption-reducing effects over long-term use. The polyurethane foam panel 16 inside the side wall of the heating box 4 is made using fluorine-free foaming technology, balancing lightweight and strength, providing balanced insulation performance, and is environmentally friendly and sustainable, meeting insulation requirements while achieving energy conservation and emission reduction. The outer shell 14, made of rigid polyurethane foam, has a low density, good thermal insulation, and impact resistance. Its closed-cell structure effectively blocks heat, improving energy efficiency; it is also corrosion-resistant and moisture-proof, making it suitable for various environments.

[0028] The inner walls of both the cooling box 3 and the heating box 4 are made of PCM aluminum plate, which is a composite structure formed by spraying phase change material PCM (Phase Change Material) onto the surface of the aluminum plate as a substrate. It has excellent heat storage and temperature control performance and can achieve uniform temperature in both the cooling box 3 and the heating box 4. The heat-conducting aluminum plate 18 is made of recycled aluminum plate, which can realize heat conduction between the cooling box and the heat storage box, and between the heating box and the cold storage box. The heat-conducting plate 17 is made of thermal grease material, which can realize heat conduction between the heat storage box and the cold storage box.

[0029] In the specific design, the heat storage box 12 has an outer shell made of recycled aluminum plate, an internal PP frame, and is filled with a heat storage phase change material. The heat storage phase change material can be expanded graphite-based CaxZny(OH)2(X+y) composite heat storage material or stearic acid / bentonite nanocomposite phase change heat storage material. It achieves heat energy storage and release through phase change: when the ambient temperature is higher than the phase change temperature, it absorbs heat and melts to store heat; conversely, it solidifies and releases heat when the temperature is lower. At the same time, the cold storage box 13 has an outer shell made of polycarbonate and is filled with a cold storage phase change material. The cold storage phase change material is a palm oil derivative phase change material, such as a coconut oil derivative. It uses solid-liquid phase change to complete cold storage: when the temperature is lower than the phase change point, it releases heat and solidifies to store cold; when the temperature is higher, it absorbs heat and melts to release cold.

[0030] The aforementioned structure, after physical processing and circuit connection, enables the cooling box 3 to perform cooling and the heating box 4 to perform heating after being powered on; and after repeated testing with a temperature gun, it can achieve the expected cooling and heating effects, demonstrating excellent performance after testing.

[0031] Further optimize the above solution, such as Figure 2 , 5As shown in Figure 6, the system also includes a thermal coupling assembly, comprising a first electromagnetic lock 29, a second electromagnetic lock 30, and four temperature sensors 31. The first electromagnetic lock 29 is mounted on a heat-conducting aluminum plate 18 at the bottom of the refrigeration box 3, connecting the heat storage box 8 and the heating box 9. Two temperature sensors 31 are respectively inserted into the heat-conducting aluminum plates 18 on both sides of the first electromagnetic lock 29. The first electromagnetic lock 29 is used to control the connection and disconnection of the heat-conducting aluminum plate 18. The second electromagnetic lock 30 is mounted on a heat-conducting aluminum plate 18 at the bottom of the heating box 8, connecting the cold storage box 3 and the refrigeration box 3. Two temperature sensors 31 are respectively inserted into the heat-conducting aluminum plates 18 on both sides of the second electromagnetic lock 30. The second electromagnetic lock 30 is used to control the connection and disconnection of the heat-conducting aluminum plate 18. The first electromagnetic lock 29, the second electromagnetic lock 30, and the four temperature sensors 31 are all connected to a power supply and a controller. The first electromagnetic lock 29 is connected in series with a first semiconductor, and the second electromagnetic lock 30 is connected in series with a second semiconductor. In specific manufacturing, the upper ends of the heat-conducting aluminum plates 18 between the refrigeration box 3 and the heat storage box 8, and between the heating box 4 and the cold storage box 9, are crossed and connected to the lower ends of the recycled aluminum plates 14 on the side walls of the heating box 4 and the refrigeration box 3. The parts of the heat-conducting aluminum plates 18 that cross each other are covered with vacuum insulation sleeves 32. The lower ends of the heat-conducting aluminum plates 18 on both sides are provided with notches 33 between the ends of the recycled aluminum plates 14 at the bottom of the refrigeration box 3 and the heating box 4, respectively. The lock cores of the first electromagnetic lock 29 and the second electromagnetic lock 30 are connected to the heat-conducting insert plate 34. The heat-conducting insert plate 34 can be inserted into the notch 33 to facilitate the heat conduction between the heat storage box 8 and the heating box 4, and between the cold storage box 9 and the refrigeration box 3.

[0032] The working principle of the thermal coupling component is as follows: (1) When the first switch 35 and the second switch 36 controlling the first semiconductor 6 and the second semiconductor 7 are closed simultaneously, the first electromagnetic lock 29 and the second electromagnetic lock 30 are activated simultaneously. The lock core pops out upwards, driving the heat-conducting plate to connect the heat-conducting aluminum plate 18 between the heat storage box and the heating box, and between the cold storage box and the cooling box, respectively. This activates the thermal coupling assembly, prioritizing the use of the heat generated at the bottom of the first semiconductor 6 and the cold energy generated at the bottom of the second semiconductor 7. The unused heat and cold energy will enter the lower heat storage box and cold storage box, and then be neutralized by the heat-conducting plate.

[0033] During equipment operation, the temperature sensor 31, inserted into the heat-conducting aluminum plate 18, can monitor the temperature difference between the first electromagnetic lock 29 and the second electromagnetic lock 30 in real time, transmitting the temperature difference signal to the controller for evaluation, so as to control the start and stop of the first and second electromagnetic locks. Taking the first electromagnetic lock as an example: if the temperature on the left side is greater than the temperature on the right side, heat is spontaneously conducted from high to low, and the heat is transferred from the hot end of the first semiconductor at the bottom of the refrigeration box to the heating box, and waste heat can be utilized. If the temperature on the left side is less than the temperature on the right side, in order to prevent the energy of the hot end of the second semiconductor at the bottom of the heating box from being conducted out and causing heat loss, the controller adjusts the lock core of the first electromagnetic lock to retract through current feedback, and the heat-conducting plate retracts, which can disconnect the heat-conducting aluminum plate between the bottom of the heating box and the heat storage box.

[0034] (2) When only cooling or heating is needed, only the cooling box 3 or the heating box 4 needs to be operated. Simply close the first switch 35 or the second switch 36. At this time, the first electromagnetic lock 29 or the second electromagnetic lock 30 is energized, and only one side of the heat-conducting aluminum plate will be connected. Taking the opening of the cooling box as an example, the first switch 35 is closed and the first electromagnetic lock 29 is energized. The heat storage box supplies heat to the heating box, but the cold storage box will not supply cold to the cooling box.

[0035] In specific embodiments of this utility model, such as Figure 1 , 2 As shown, the heat sink includes a miniature electric fan 21 disposed within a heat dissipation cavity 20. The heat dissipation cavity 20 is a hollow cavity with heat dissipation holes 22 around its perimeter. The miniature electric fan 21 is located below the refrigeration box 3. The miniature electric fan is a YCA1804 miniature electric fan, which dissipates heat from the cold storage box and the hot storage box during the cooling and heating process, playing an auxiliary heat dissipation role and ensuring the normal operation of the product.

[0036] In specific embodiments of this utility model, such as Figure 7 As shown, the power source includes a storage battery and a backup battery. The storage battery is located inside the side wall of the housing 1, and the outside of the housing 1 is provided with a socket for electrical connection to the storage battery. The backup battery is a solar cell 26. The plug at the end of the wire 25 of the solar cell 26 can be inserted into the socket of the housing 1 to charge the storage battery. The bottom of the solar cell 26 is attached to the top of the car by a suction cup 28. The top and all sides of the solar cell 26 are provided with photovoltaic panels 27. The photovoltaic panels 27 are connected to the solar cell 26 through a solar controller, which can be integrated into the housing of the solar cell.

[0037] Further optimize the above structure, such as Figure 1As shown, a handle 24 is provided on the outside of the box 1 for easy handling; casters 23 are provided at the four corners of the bottom of the box 1, allowing it to be moved to any location. Additionally, photovoltaic modules can be installed on the top of the box cover 2. These photovoltaic modules are connected to the battery via a photovoltaic controller, which can extend the power supply's operating time.

[0038] In summary, this utility model has the following beneficial effects: (1) The Peltier effect of semiconductors is used to cool and heat the heating and cooling boxes of the temperature control box. At the same time, the dual temperature control of cold and hot can be intelligently switched to meet diverse needs.

[0039] (2) Solar cells provide power to the semiconductor cooling chip, eliminating the need for an external power source, effectively reducing reliance on traditional energy sources and lowering energy consumption and carbon emissions. During outdoor trips or long journeys, solar energy can be used to power the temperature control box anytime, anywhere, enabling green travel and practicing environmental protection principles.

[0040] (3) This utility model does not use traditional refrigerants, has no risk of chemical reagent leakage, and achieves zero pollution and zero emissions.

[0041] (4) Adopting an independent partition design, partitioned storage avoids cross-influence between cold and hot, ensures that refrigeration and heating functions do not interfere with each other, meets diverse food storage needs, and improves ease of use and practicality.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
