Description

Technical Field

[0001] This utility model relates to a vehicle heating system and a vehicle, belonging to the field of vehicle control technology. Background Technology

[0002] For vehicles, especially buses, the comfort of passenger cabin heating is crucial to passenger comfort during winter. Currently, traditional buses primarily rely on forced-air radiators installed under the seats to blow hot air into the passenger cabin for heating. Figure 1 As shown. Due to the noticeable airflow from the forced radiator, the hot air blown out is mainly directed at the feet and ankles, with the temperature reaching nearly 50 degrees Celsius. This causes a burning sensation in the feet, resulting in a significant temperature difference between the feet and the head. Furthermore, the fans used in the forced radiator are noisy, affecting the passenger experience.

[0003] Therefore, to improve passenger comfort, in addition to installing forced radiators 7 under the seats, roof-mounted pure electric air conditioners 8 are also being installed in new energy vehicles, such as... Figure 2 As shown, the pure electric air conditioner can blow hot air directly at people's heads, which alleviates the problem of large temperature difference between the feet and the head to some extent. However, since the entire passenger cabin is equipped with forced radiators under the seats, the noise of the forced radiators is still very loud when heating, and the forced radiator wind is obvious, making people feel hot and seriously affecting the passengers' comfort. Utility Model Content

[0004] The purpose of this utility model is to provide a vehicle heating system and vehicle to solve the problems of high noise and discomfort caused by the current use of forced radiators installed under the seats for heating in vehicles.

[0005] This utility model provides a vehicle heating system to solve the above-mentioned technical problems, including a radiator installed inside the vehicle. The radiator includes a heat dissipation core for being installed on the bottom of the left and right sides of the vehicle and extending along the front-rear direction of the vehicle. The heat dissipation core includes a natural heat dissipation section and a forced heat dissipation section with a heat dissipation fan installed on the side facing away from the passenger compartment. The forced heat dissipation section is at least installed near the vehicle door to balance the temperature inside the passenger compartment.

[0006] Furthermore, the forced heat dissipation section is also used in locations other than near the vehicle door and where there are no other forced heat dissipation sections within a certain distance.

[0007] Furthermore, the forced cooling sections on the left and right sides of the vehicle are staggered to avoid convection between the air inlet of the cooling fan in the forced cooling section on one side and the air outlet of the cooling fan in the forced cooling section on the other side.

[0008] Furthermore, the heating system also includes a vehicle air conditioning system. When the vehicle is a new energy vehicle, the air conditioning system is a pure electric air conditioning system; when the vehicle is a non-new energy vehicle, the air conditioning system achieves heating through a heat dissipation core installed inside it. This heat dissipation core is installed on the top of the left and right sides of the vehicle and extends along the front and rear direction of the vehicle.

[0009] Furthermore, a first solenoid valve is installed at the water inlet of the pipe where the heat dissipation core is located. The opening degree of the solenoid valve is controlled by the radiator control unit according to the temperature inside the vehicle, so as to adjust the temperature inside the vehicle by adjusting the water inlet of the pipe where the heat dissipation core is located; the temperature inside the vehicle is determined by the temperature collected by temperature sensors installed at different locations inside the vehicle.

[0010] Furthermore, when the vehicle is a non-new energy vehicle, a second solenoid valve is installed on the pipe where the heat dissipation core is located inside the air conditioning unit. The second solenoid valve is controlled by the radiator control unit according to the temperature inside the vehicle. The temperature adjustment of the air conditioning unit is achieved by controlling the opening degree of the second solenoid valve through the radiator control unit. The temperature inside the vehicle is determined by the temperature collected by temperature sensors installed at different locations inside the vehicle.

[0011] Furthermore, there are three temperature sensors, which are respectively installed in the front, middle and rear areas of the vehicle compartment. The average temperature collected by the temperature sensors in the front and middle areas is the front area temperature, and the average temperature collected by the temperature sensors in the middle and rear areas is the rear area temperature. The temperature inside the vehicle is determined by combining the front area temperature and the rear area temperature.

[0012] The beneficial effects of this utility model are as follows: As an improved invention, this utility model replaces the multiple forced radiators originally located under the seats with a continuous radiator extending along the vehicle direction. The heat dissipation core of this continuous radiator is divided into a natural heat dissipation section and a forced heat dissipation section with a cooling fan located on the side facing away from the passenger compartment. The forced heat dissipation section is mainly located near the vehicle doors to balance the temperature inside the passenger compartment. Therefore, this utility model replaces the multiple forced radiators currently located at the bottom of the vehicle with a continuous natural radiator, and adds forced radiators near the doors where heating needs cannot be met, significantly reducing the use of cooling fans, lowering heating system noise, reducing the discomfort caused by direct airflow from forced radiators, improving passenger comfort, and ensuring heating efficiency.

[0013] This utility model also provides a vehicle, including a vehicle body and doors, and a radiator installed inside the vehicle. The radiator includes a heat dissipation core installed at the bottom of the left and right sides of the vehicle and extending along the front-rear direction of the vehicle. The heat dissipation core includes a natural heat dissipation section and a forced heat dissipation section with a heat dissipation fan installed on the side facing away from the passenger compartment. The forced heat dissipation section is installed at least near the vehicle doors to balance the temperature inside the passenger compartment.

[0014] Furthermore, the forced heat dissipation section is also located in a place that is not near the doorway and where there are no other forced heat dissipation sections within a certain distance.

[0015] Furthermore, the forced cooling sections on the left and right sides of the vehicle are staggered to avoid convection between the air inlet of the cooling fan in the forced cooling section on one side and the air outlet of the cooling fan in the forced cooling section on the other side.

[0016] Furthermore, it also includes a vehicle air conditioning system. When the vehicle is a new energy vehicle, the air conditioning system is a pure electric air conditioning system; when the vehicle is a non-new energy vehicle, the air conditioning system achieves heating through a heat dissipation core installed inside it. This heat dissipation core is installed on the top of the left and right sides of the vehicle and extends along the front and rear direction of the vehicle.

[0017] Furthermore, a first solenoid valve is installed at the water inlet of the pipe where the heat dissipation core is located. The opening degree of the solenoid valve is controlled by the radiator control unit according to the temperature inside the vehicle, so as to adjust the temperature inside the vehicle by adjusting the water inlet of the pipe where the heat dissipation core is located; the temperature inside the vehicle is determined by the temperature collected by temperature sensors installed at different locations inside the vehicle.

[0018] Furthermore, when the vehicle is a non-new energy vehicle, a second solenoid valve is installed on the pipe where the heat dissipation core is located inside the air conditioning unit. The second solenoid valve is controlled by the radiator control unit according to the temperature inside the vehicle. The temperature adjustment of the air conditioning unit is achieved by controlling the opening degree of the second solenoid valve through the radiator control unit. The temperature inside the vehicle is determined by the temperature collected by temperature sensors installed at different locations inside the vehicle.

[0019] Furthermore, there are three temperature sensors, which are respectively installed in the front, middle and rear areas of the vehicle compartment. The average temperature collected by the temperature sensors in the front and middle areas is the front area temperature, and the average temperature collected by the temperature sensors in the middle and rear areas is the rear area temperature.

Detailed Implementation

[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0029] This invention replaces the current forced radiator at the bottom of the vehicle with a continuous natural radiator, and adds a forced radiator near the door where heating needs cannot be met, thereby solving the problems of loud noise and strong wind caused by the forced radiator, which result in a poor passenger experience.

[0030] Vehicle Example 1

[0031] The following explanation uses a traditional vehicle, i.e., a non-new energy vehicle, as an example. In this embodiment, the non-new energy vehicle refers to a traditional bus. A traditional bus includes a passenger cabin area with multiple rows of seats. To achieve overall heating of the passenger cabin area, the heating system used in this invention includes a heat dissipation core located at the bottom of both sides of the vehicle and extending along the front-to-back direction. This heat dissipation core uses natural wind for heat dissipation, thus avoiding noise interference from the fan. Considering that the doors are frequently opened, causing rapid heat loss near the doors and affecting the comfort of passengers in that area, this invention also installs a cooling fan at the heat dissipation core near the vehicle doors to assist in heat dissipation, balance the temperature inside the cabin, and prevent insufficient heating in the area near the doors. Therefore, the heat dissipation core of this invention includes a natural heat dissipation section and a forced heat dissipation section. The natural heat dissipation section (also called a natural radiator) refers to the heat dissipation core relying solely on natural wind for heat dissipation without relying on a cooling fan, while the forced heat dissipation section (also called a forced radiator) requires a cooling fan for heat dissipation. A cooling fan is installed on the side of the forced heat dissipation section facing away from the passenger cabin to achieve forced heat dissipation.

[0032] like Figure 4 As shown, since the vehicle in this embodiment has three doors—the front door 1, the middle door 2, and the emergency door 3—the heat dissipation core, located on the bottom of the left and right sides of the vehicle and extending along the front-rear direction, is divided into four natural heat dissipation sections 5 and three forced heat dissipation sections 4. The forced heat dissipation sections in this embodiment are located near the doors. "Near the doors" here includes locations close to the door on the same side as the door and locations close to the door on the opposite side. Figure 4 As shown, a forced heat dissipation section 4 is set near the front door 1, and another forced heat dissipation section 4 is set near the emergency door 3. Considering that the emergency door 3 is on the opposite side of the middle door 2 and is relatively close, the forced heat dissipation section 4 near the emergency door 3 can also compensate for the heat near the middle door 2 to a certain extent, so as to meet the heating needs of the middle door 2. This setting also takes into account that the emergency door 3 is on the opposite side of the middle door 2. If forced heat dissipation sections are set near both the emergency door 3 and the middle door 2, it will cause the air inlet of the cooling fan in the forced heat dissipation section on one side of the vehicle to form convection with the air outlet of the cooling fan in the forced heat dissipation section on the opposite side, affecting the heat dissipation effect. Therefore, if the two doors of the vehicle are arranged opposite each other, this utility model only sets a forced heat dissipation section near one side of the door. In addition, in order to improve the temperature uniformity of the vehicle, this utility model also sets forced heat dissipation sections in places other than the doors and where there are no other forced heat dissipation sections within a certain distance, such as Figure 4 As shown, since the rear area of ​​the vehicle interior on the side where the middle door is located is equipped with natural heat dissipation sections, its heating effect is definitely worse than that of the forced heat dissipation sections in the middle door and front door areas. Therefore, in this embodiment, a forced heat dissipation section is also provided in the rear area of ​​the vehicle on the side where the middle door is located.

[0033] To adjust the temperature inside the vehicle, this invention also includes a first solenoid valve at the inlet of the pipe containing the radiator core. The opening degree of this solenoid valve is controlled by the radiator control unit based on the temperature inside the vehicle. Figure 5 As shown, the radiator control unit (also called the radiator control box) collects the temperature inside the vehicle through a temperature sensor. When the temperature inside the vehicle is higher than the set value, the radiator control box outputs a signal to reduce the opening of the first solenoid valve, thereby reducing the flow rate in the pipe where the radiator core is located, thus lowering the temperature inside the vehicle; conversely, the same applies. Therefore, this invention regulates the temperature inside the vehicle through a solenoid valve, avoiding large temperature fluctuations and improving comfort. Since the vehicle compartment is relatively large, if only one temperature sensor is installed, inaccurate measurements may occur due to measurement errors or temperature differences between different areas. This invention allows for multiple temperature sensors, each installed in different areas of the vehicle. In this embodiment, three temperature sensors are used, installed in the front, middle, and rear areas of the vehicle compartment. The average temperature collected by the temperature sensors in the front and middle areas is the front area temperature, and the average temperature collected by the temperature sensors in the middle and rear areas is the rear area temperature. The temperature inside the vehicle is determined by combining the front and rear temperatures; for example, the average of the front and rear temperatures can be used as the vehicle interior temperature.

[0034] To further improve the temperature uniformity inside the vehicle, the heat dissipation core of this invention uses a U-shaped pipe, allowing the inlet and outlet of the pipe to be located together. This embodiment is designed for traditional vehicles, such as... Figure 5 As shown, the heating of the pipe where the heat dissipation core is located can utilize the waste heat of the engine. To improve the heating effect, an additional heater can be added.

[0035] Since the heat dissipation core is located at the bottom of the vehicle, under the seats, the primary area warmed is the feet and ankles, while the head remains relatively cool, affecting passenger comfort. Therefore, this invention also incorporates a traditional vehicle air conditioning system 9, such as... Figure 3 As shown. Since this embodiment targets a traditional vehicle, whose air conditioning is generally for cooling and cannot provide heating, this invention, based on existing vehicle air conditioning systems, incorporates a heat dissipation core inside the air conditioning unit to achieve heating. This heat dissipation core can be installed on the top of the left and right sides of the vehicle, extending along the front-to-back direction. To achieve temperature regulation, this invention also includes a second solenoid valve on the pipe where the heat dissipation core is located inside the vehicle air conditioning unit. The second solenoid valve is also connected to the radiator control unit, which controls it based on the vehicle interior temperature. The vehicle interior temperature used for control is the same as that used by the first solenoid valve. Figure 5 As shown, when the temperature is too high, the radiator control unit controls the opening of the second solenoid valve to decrease, and when the temperature is too low, the radiator control unit controls the opening of the second solenoid valve to increase.

[0036] Considering that the human body's feet and head feel temperature differently, with the head generally needing a lower temperature than the feet, the radiator control unit can adjust the first and second solenoid valves differently based on the vehicle's interior temperature. The roof-mounted air conditioning system blows air at 20% capacity, producing a weak stream of warm air that helps circulate warm air inside the vehicle.

[0037] Vehicle Example 2

[0038] The vehicle in this embodiment is a new energy vehicle. For this new energy vehicle, its heating system is similar to the heating system in Vehicle Embodiment 1, with the following differences: 1) The air conditioning used in new energy vehicles is generally a roof-mounted pure electric air conditioner, such as... Figure 6 As shown, the roof-mounted pure electric air conditioner can convert electrical energy into heat energy to achieve heating. In this case, the temperature of the roof-mounted pure electric air conditioner can be adjusted by the air conditioner's own controller. 2) Since it is a new energy vehicle, the heating of the pipeline where the heat dissipation core is located needs to be increased by adding an independent heater. In order not to affect the normal operation of the vehicle, the heater here can be a fuel heater or a PTC heater.
