Description

Technical Field

[0001] This invention relates to the field of in-vehicle facilities technology, and in particular to an in-vehicle hot and cold water dispenser system. Background Technology

[0002] To provide hot and cold drinking water in vehicles, most existing vehicles equipped with hot and cold drinking water functions are single-function devices, mainly using the original air conditioning system to achieve the function of cold or hot air; some use non-vehicle integrated electronic quick-cold and hot cup products; and some commercial vehicles are equipped with electronic water dispensers.

[0003] The original air conditioning system requires the air conditioning to be on to provide both cold air and cold water, making it unable to respond to users' needs for hot or cold drinking water in the vehicle. When the air conditioning is on, it only operates in cold air mode and heating mode mode, and it cannot function when the air conditioning is off. Using a separate electronic hot / cold cup or water dispenser, however, provides both hot and cold air within the vehicle cabin, potentially negatively impacting the interior environment. Summary of the Invention

It can achieve continuous operation of hot and cold water functions without starting the vehicle's air conditioning system. The whole process does not require any refrigerant and therefore does not generate any pollution sources.

[0005] To achieve the above objectives, the present invention provides the following solution: The present invention provides a vehicle-mounted hot and cold water dispenser system, comprising: A placement platform is provided with a heat exchange section, which is used to support a liquid container and is connected to the liquid container for heat exchange.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The purpose of this invention is to provide a vehicle-mounted hot and cold water dispenser system to solve the problems existing in the prior art. It can achieve continuous operation of hot and cold water functions without starting the vehicle's air conditioning system. The whole process does not require any refrigerant and therefore does not generate any pollution sources.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 As shown, the present invention provides a vehicle-mounted hot and cold water dispenser system, including a placement platform 4, a semiconductor cooler 10, and a power supply 1. The placement platform 4 is provided with a heat exchange section for supporting a liquid container 3 and is heat-exchange connected to the liquid container 3. The semiconductor cooler 10 is provided with an energy supply surface 14 and a heat exchange surface 15. The energy supply surface 14 is used for cooling or heating and is heat-exchange connected to the heat exchange section to ensure that the temperature of the liquid in the liquid container 3 can be adjusted from 80°C to -20°C. The heat exchange surface 15 is used for heat dissipation or heat absorption and is heat-exchange connected to a radiator 11. The power supply 1 and the semiconductor cooler 10 are connected to the semiconductor cooler 10. The cooler 10 is electrically connected and equipped with a controller 2, which switches the voltage polarity of the power supply 1 to the thermoelectric cooler 10. The power supply 1 supplies power to the controller 2 via an input line, and the controller 2 supplies power to the thermoelectric cooler 10 via an output line. The power supply 1 typically uses the vehicle's onboard DC 12V or DC 24V power supply. With the vehicle's onboard power supply, it can achieve the cooling or heating function of the liquid container 3 without the need for a transformer. The appropriate onboard power supply can be selected according to actual needs, or adjusted via the controller 2. Furthermore, the power supply 1 is electrically connected to the thermoelectric cooler 10 via the controller 2, allowing for adjustments as needed when supplying power to the thermoelectric cooler 10. For example, in some cases, the controller 2 may first set both voltage and current limits to their minimum values, then gradually increase the voltage while monitoring the current to ensure it does not exceed the maximum allowable current of the thermoelectric cooler 10.

[0022] For heating or cooling the water in the liquid container 3, the placement platform 4 includes a support structure and a heat exchanger. The support structure is installed at a corresponding position in the vehicle's interior space, and the heat exchanger is installed on the support structure, which in turn supports both the heat exchanger and the liquid container 3. For example, the heat exchanger can be a heat-conducting panel mounted on the support structure, and the liquid container 3 can be a flat-bottomed cup or pitcher, placed snugly on the heat-conducting panel to achieve surface-to-surface heat transfer and maximize heating efficiency. Furthermore, to ensure the stability of the liquid container 3, it is preferable to have a receiving groove on the heat-conducting panel to fit into the bottom of the liquid container 3, ensuring the stability of the liquid during vehicle movement.

[0023] To improve the heat exchange effect of the semiconductor cooler 10, in this embodiment, the semiconductor cooler 10 has an overall plate-like structure, with its two side planar structures serving as the power supply surface 14 and the heat exchange surface 15, thereby ensuring the area of ​​its power supply surface 14 and heat exchange surface 15.

[0024] This invention discloses a vehicle-mounted hot and cold water dispenser system. During the cooling process, the power supply 1 supplies power to the controller 2 through the input line, and the controller 2 supplies positive and negative power to the semiconductor cooler 10 through the output line, causing the power supply surface 14 of the semiconductor cooler 10 to cool, while its heat exchange surface 15 generates heat. It should be noted that the semiconductor cooler 10 is characterized by one side cooling while the other side naturally generates heat. In order to maintain continuous cooling, heat must be continuously dissipated from the side of the semiconductor cooler 10 that generates heat. The power supply surface 14 of the semiconductor cooler 10 is heat-exchange connected to the heat exchange section, transferring the cold energy to the heat exchange section. The heat exchange section is heat-exchange connected to the liquid container 3, thereby ultimately transferring the cold energy to the liquid in the liquid container 3. At the same time, the radiator 11 dissipates the heat generated by the heat exchange surface 15 to the outside environment, thus cooling the liquid.

[0025] During the heating process, the voltage polarity of the power supply 1 to the semiconductor cooler 10 is switched by the controller 2, so that the power supply surface 14 of the semiconductor cooler 10 heats up and its heat exchange surface 15 generates cooling. The power supply surface 14 of the semiconductor cooler 10 is connected to the heat exchange section for heat exchange, and the heat is conducted to the heat exchange section. The heat exchange section is connected to the liquid container 3 for heat exchange, and the heat is finally conducted to the liquid in the liquid container 3.

[0026] This invention discloses a vehicle-mounted hot and cold water dispenser system that employs semiconductor cooler 10 technology. The power supply surface 14 of the semiconductor cooler 10 is connected to a heat exchange section, transferring the cold or heat generated by the power supply surface 14 to the heat exchange section and the liquid container 3. This heats or cools the liquid in the container 3, providing hot or cold drinking water. As can be seen from the heating method described above, the power supply 1 required by this invention is simply a low-voltage vehicle power supply, which is sufficient to power the semiconductor cooler 10. Furthermore, the continuous operation of the hot and cold drinking function can be achieved without starting the vehicle's air conditioning system. The entire process requires no refrigerant, thus eliminating any pollution sources. Moreover, the entire vehicle-mounted hot and cold water dispenser system exhibits low vibration and noise during operation, has a long lifespan, and is easy to install.

[0027] To minimize the impact on the in-vehicle environment, in one specific embodiment, the placement platform 4 is located in the in-vehicle space, while the semiconductor cooler 10 and radiator 11 are located in the out-of-vehicle space. When the liquid container 3 is heated or cooled using the in-vehicle hot and cold water dispenser system disclosed in this invention, the heat or cold generated is discharged to the out-of-vehicle space after the heat exchange surface 15 is heated by the radiator 11. Since the semiconductor cooler 10 is also located in the out-of-vehicle space, the unused heat and cold generated at the power supply surface 14 and heat exchange surface 15 of the semiconductor cooler 10 are directly discharged to the out-of-vehicle space, thus fully avoiding impacting the environment inside the vehicle.

[0028] In this embodiment, to enable the semiconductor cooler 10 and radiator 11 to be installed in the external space of the vehicle, a heat exchange circuit 8 is provided between the power supply surface 14 and the heat exchange section. The heat exchange circuit 8 is provided with a first heat exchanger 9 and a second heat exchanger 5. The first heat exchanger 9 is heat-exchange connected to the power supply surface 14, and the second heat exchanger 5 is heat-exchange connected to the heat exchange section. A first heat exchange medium is circulated within the heat exchange circuit 8. The first heat exchanger 9 is used to transfer the cold or heat generated by the power supply surface 14 of the semiconductor cooler 10 to the first heat exchange medium in the heat exchange circuit 8. The first heat exchange medium then transfers the cold or heat to the heat exchange section of the placement platform 4 to conduct heat to the liquid container 3, thereby achieving cooling or heating of the liquid container 3 and realizing the function of heating or cooling drinking water. To ensure heating uniformity and reduce operating costs, the first heat exchange medium is preferably made of heat transfer oil or the like.

[0029] Based on the above implementation, a first circulation pump 7 is provided on the heat exchange circuit 8. That is, the circulation of the first heat exchange medium on the heat exchange circuit 8 is accomplished by the first circulation pump 7. The first circulation pump 7 is electrically connected to the controller 2 so that when the power supply 1 is turned on to supply power to the semiconductor cooler 10, the controller 2 starts the first circulation pump 7 at the required time node.

[0030] To ensure that the liquid container 3 is heated to the required temperature, in this embodiment, a first temperature sensor 6 is provided on the second heat exchanger 5 or the placement platform 4 to monitor the temperature of the second heat exchanger 5 or the heat exchange section. The first temperature sensor 6 is electrically connected to the controller 2 to ensure that the controller 2 performs closed-loop control based on the feedback from the first temperature sensor 6, so that the liquid container 3 is always maintained at the required temperature. The controller 2 is built into the vehicle's infotainment system so that the temperature can be set directly on the system, allowing for temperature adjustment to achieve the desired drinking temperature. Alternatively, the controller 2 can be built into the placement platform 4, with a display screen on the platform 4 for setting the temperature. Both the controller 2 and the display screen are insulated from the heat exchange section to ensure their lifespan.

[0031] Based on the above embodiments, both the first heat exchanger 9 and the second heat exchanger 5 are shell-and-tube heat exchangers. Both the first heat exchanger 9 and the second heat exchanger 5 include a shell portion and a tube bundle portion disposed in the shell portion. The shell portion is filled with a second heat exchange medium, and the tube bundle portion is immersed in the second heat exchange medium and connected to the heat exchange circuit 8. The shell portion of the first heat exchanger 9 is attached to the energy supply surface 14, and the shell portion of the second heat exchanger 5 is attached to the heat exchange section. The energy supply surface 14 on the semiconductor cooler 10 exchanges heat with the shell portion of the first heat exchanger 9 to heat or cool the second heat exchange medium inside it. The second heat exchange medium conducts its heat to the tube bundle portion of the first heat exchanger 9. The first heat exchange medium in the tube bundle portion is transferred to the tube bundle portion of the second heat exchanger 5 through the heat exchange circuit 8. The shell portion of the second heat exchanger 5 exchanges heat with its tube bundle portion through the second heat exchange medium inside it, and then the shell portion of the second heat exchanger 5 transfers heat to the heat exchange section of the placement platform 4.

[0032] Alternatively, a heat exchange pipeline can be installed between the shell portion of the first heat exchanger 9 and the power supply surface 14. For example, a liquid cooling plate can be laid on the power supply surface 14, with its two ends converging into two main heat exchange pipes, which are connected to the shell portion of the first heat exchanger 9. A circulation pump can be installed on either of the main heat exchange pipes to allow the second heat exchange medium to circulate back and forth between the shell portion and the liquid cooling plate, thus transferring heat. The configuration of the first heat exchanger 9 is not limited to the above method.

[0033] Similarly, a heat exchange pipeline is provided between the shell portion and the heat exchange section of the second heat exchanger 5. For example, a liquid cooling plate is laid on the heat exchange section, with its two ends converging into two main heat exchange pipes, which are connected to the shell portion of the second heat exchanger 5. A circulation pump is provided on either of the main heat exchange pipes to allow the second heat exchange medium to circulate back and forth between the shell portion and the liquid cooling plate, thus transferring heat. The arrangement of the first heat exchanger 9 is not limited to the above method.

[0034] In some special examples, the second heat exchanger 5 may also be a finned heat exchanger, which is located on one side of the heat exchange section of the placement platform 4 and is equipped with a heat exchange fan. The heat exchange fan blows air toward the finned heat exchanger to carry the heat on the surface of the finned heat exchanger to the heat exchange section, so as to realize heat exchange with the heat exchange section.

[0035] Furthermore, to ensure uniform heating and reduce operating costs, the second heat exchange medium is preferably heat transfer oil or the like.

[0036] In some cases, the radiator 11 includes a liquid cooling plate, a heat dissipation section, and a heat dissipation circulation loop. The liquid cooling plate is attached to the heat exchange surface 15. The heat dissipation section and the liquid cooling plate are spaced apart. The heat dissipation circulation loop is circulated between the liquid cooling plate and the heat dissipation section, and a third heat exchange medium is circulated inside it. The heat or cold energy on the heat exchange surface 15 is carried away by the third heat exchange medium through the liquid cooling plate and transported to the heat dissipation section through the heat dissipation circulation loop for heat exchange. After the heat exchanged by the third heat exchange medium, the liquid cooling plate is used for heat exchange again.

[0037] The heat dissipation circulation loop is equipped with a second circulation pump, which is electrically connected to the controller 2. The controller 2 controls the second circulation pump to circulate the third heat exchange medium in the heat dissipation circulation loop.

[0038] Based on the above situation, a cooling fan 12 is provided on one side of the heat dissipation part to blow air towards it for heat exchange. The cooling fan 12 is electrically connected to the controller 2 so as to improve the heat exchange efficiency of the heat dissipation part by blowing air onto the heat dissipation part through the cooling fan 12.

[0039] In other cases, the radiator 11 is a finned radiator and is attached to the heat exchange surface 15. A cooling fan 12 is provided on one side of the heat exchange surface 15 to blow air towards it for heat exchange. The cooling fan 12 is electrically connected to the controller 2 so as to improve the heat exchange efficiency of the finned radiator by blowing air onto it.

[0040] Based on the above embodiments, a second temperature sensor 13 is provided at the liquid cooling plate or finned heat sink to reflect the working condition of heat exchange on the heat exchange surface 15 of the semiconductor cooler 10 in real time.

[0041] Any adaptive changes made according to actual needs are within the scope of protection of this invention.
