Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle air conditioning systems, and in particular relates to an automotive heating device. Background Technology

[0002] The existing mass-produced vehicle air conditioning systems mainly employ two technical solutions for heating the rear seats: one is to directly utilize the front air vents; the other is to use a centrifugal fan connected to ductwork to guide the warm air from the front vents to the rear seats.

[0003] The first solution mentioned above has insufficient rear-seat heating performance and cannot meet the comfort requirements of users in low-temperature winter environments. Compared with the first solution, the second solution has significantly improved heating performance, but the air volume is still greatly limited and cannot meet the comfort requirements of users in extremely cold environments. Moreover, this solution has many limitations in the layout of the vehicle's interior space, the control method is complex, the operation is inconvenient, it is prone to failure, and it increases maintenance costs and difficulty of use.

[0004] Meanwhile, in both of the above-mentioned heating solutions, the rear and front heating systems are controlled through the front air conditioning panel, making it difficult for rear passengers to flexibly adjust the rear temperature. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an automotive heating device to solve the problem that the existing technical solution of using the front heating air for rear seat heating cannot meet the comfort requirements of users in extremely cold environments.

[0006] To achieve the above and other related objectives, this utility model provides an automotive heating device, comprising:

[0007] The cooling system is used to cool the car engine. The cooling system includes an inlet pipe and an outlet pipe. Cold coolant enters the cooling system through the inlet pipe, and hot coolant flows out of the cooling system through the outlet pipe.

[0008] The front heating assembly includes a front core and a front fan; the front core is connected to the cooling pipes, and hot coolant flows into the front core from the outlet pipe, becomes cold coolant, and then flows into the cooling pipes from the inlet pipe; the front fan delivers the heat from the front core to the front seats.

[0009] The rear heating assembly is installed under the front seats of the car and includes the rear heating element and the rear fan.

[0010] A branch pipe for liquid outlet is connected to the liquid outlet pipe. Part of the hot coolant flowing out of the liquid outlet pipe enters the front core, and another part enters the rear core from the liquid outlet branch pipe. The rear fan delivers the heat of the rear core to the rear seats.

[0011] A liquid inlet branch pipe is connected to the liquid inlet pipe, and the cold coolant flowing out from the rear mechanism flows into the liquid inlet pipe through the liquid inlet branch pipe.

[0012] As described above, the automobile heating device of this utility model has at least the following beneficial effects:

[0013] This automotive heating system features a rear heater assembly installed under the front seats. A branch pipe connects to the outlet pipe, and a branch pipe connects to the inlet pipe. Hot coolant flowing from the cooling system enters the front and rear engine modules via the outlet and branch pipes, respectively. Front and rear fans blow heat from the engine modules to the passengers in the front and rear seats. The cooled coolant then flows back into the cooling system via the inlet and branch pipes. This design offers advantages over existing solutions that rely solely on the front heater vents or use centrifugal fans connected to ducts to direct warm air from the front vents to the rear seats. This car heating system boasts superior heating performance, meeting the comfort requirements of users in both low-temperature and extremely cold winter environments. Furthermore, it utilizes the hot coolant in the engine cooling system to provide heat, simultaneously heating the vehicle interior and lowering the engine temperature, thus saving energy. Compared to adding a separate heating device, it saves interior space. The seamless integration of the cooling system and the heating water circuit ensures system stability and reliability, reducing the probability of malfunctions and improving the overall vehicle's durability and freeze resistance—truly a four-in-one benefit.

[0019] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0020] Please see Figures 1 to 3 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0021] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0022] This utility model provides an automotive heating device to solve the problem that existing technologies, which rely on front-row heating for rear-seat heating, cannot meet the comfort requirements of users in extremely cold environments, and have complex control methods, making it difficult for rear-seat users to flexibly adjust the rear temperature. This automotive heating device includes:

[0023] like Figure 1 The cooling pipe 1 shown is used to cool the car engine. The cooling pipe 1 includes an inlet pipe 11 and an outlet pipe 12. Cold coolant enters the cooling pipe 1 through the inlet pipe 11. After the cold coolant takes away the heat inside the engine, it becomes hot coolant. The hot coolant then flows out of the cooling pipe 1 through the outlet pipe 12.

[0024] like Figure 1 The front heater assembly 2 shown includes a front core 21 and a front fan 22. The front core 21 is connected to the cooling pipe 1. Hot coolant flows into the front core 21 from the outlet pipe 12. The front fan 22 blows the heat from the front core 21 to the front seats. After the hot coolant is cooled down, it becomes cold coolant and then flows into the cooling pipe 1 from the inlet pipe 11.

[0025] like Figure 1 The rear heating assembly 3 shown is installed under the front seats of the car and includes a rear core and a rear fan.

[0026] like Figure 1 The liquid outlet branch pipe 4 shown is connected to the liquid outlet pipe 12. Part of the hot coolant flowing out of the liquid outlet pipe 12 enters the front core 21, and the other part enters the rear core from the liquid outlet branch pipe 4. The rear fan delivers the heat of the rear core to the rear seats.

[0027] The inlet branch pipe 5 is connected to the inlet pipe 11. The hot coolant is cooled down in the rear mechanism and becomes cold coolant. It flows from the inlet branch pipe 5 into the inlet pipe 11 and finally returns to the cooling pipe 1.

[0028] This automotive heating system features a rear heater assembly 3 installed under the front seats. A branch pipe 4 is connected to the outlet pipe 12, and a branch pipe 5 is connected to the inlet pipe 11. Hot coolant flowing from the cooling system 1 enters the front and rear heating elements 21 and 21 respectively through the outlet pipe 12 and branch pipe 4. Front and rear fans blow heat from the front and rear heating elements to the passengers in the front and rear seats. The cooled coolant then flows back into the cooling system 1 through the inlet pipe 11 and branch pipe 5. Compared to existing technologies that directly utilize the front heater vents or use a single centrifugal fan connected to ducts to direct warm air from the front vents to the rear seats, this automotive heating system offers superior heating performance. This vehicle heating system meets the comfort requirements of users in low-temperature winter environments, and also satisfies the comfort requirements of users in extremely cold environments. Furthermore, it utilizes the hot coolant in the engine cooling pipe 1 to provide heat, simultaneously heating the vehicle interior and lowering the engine temperature, thus saving energy. Compared to adding a separate heating device, it saves interior space. The close integration of the cooling pipe 1 and the heating system's hot water circuit ensures system stability and reliability, reduces the probability of malfunctions, and improves the overall vehicle's durability and freeze resistance. It achieves four benefits in one go. It solves the problem that existing technologies using rear-seat heating that borrows front-seat heating cannot meet the comfort requirements of users in extremely cold environments, and also suffer from complex control methods.

[0029] like Figure 1As shown, an electromagnetic water valve 61 is installed on the outlet branch pipe 4 to control the flow rate of hot coolant flowing into the rear engine core. The electromagnetic water valve 61 is controlled by a flow switch 62 located in the rear of the car. Of course, electromagnetic water valves 61 can also be installed on the outlet pipe 12 and the inlet pipe 11. Since this heating equipment mainly improves the rear heating technology compared to existing technologies, it will not be elaborated on here. The front fan 22 and the rear fan are each equipped with an air volume switch 63, located in the front and rear of the car, respectively. The flow switch 62 controls the opening and closing of the electromagnetic water valve 61, thereby controlling the flow rate of hot coolant entering the rear engine core. The air volume switch 63 controls the air volume, allowing rear passengers to flexibly adjust the heating temperature, thus solving the problem that rear passengers have difficulty adjusting the rear temperature.

[0030] like Figure 1 As shown, both the flow switch 62 and the air volume switch 63 can be set with different speeds to achieve precise control over the flow rate of the hot coolant entering the rear core and to precisely control the air volume output from the front fan 22 and the rear fan. The specific speed settings can be designed as 3 or 5, which is not limited here.

[0031] In another implementation, please refer to Figure 1 and Figure 2 There are two rear heating assemblies 3, which are installed under the driver's seat and the passenger seat respectively; there are two liquid outlet branches 4, which are connected to the rear core of each of the two rear heating assemblies 3 respectively; compared with the design of a single rear heating assembly 3, the heating effect of this embodiment is better, and the passengers can be heated in any position in the rear.

[0032] In another implementation, please refer to Figure 1 The radiator assembly 7 and the thermostat assembly 8 are connected to the cooling pipe 1 via a heat dissipation pipe, and the thermostat assembly 8 is installed on the heat dissipation pipe. When the engine temperature is too high, the thermostat assembly 8 opens, and the radiator assembly 7 starts working to cool the engine's cooling pipe 1. The radiator assembly 7 and the thermostat assembly 8 have been fully disclosed in the prior art and will not be described in detail here.

[0033] In another implementation, please refer to Figure 2 A bracket is welded under the front seats of the car, and the rear heating assembly 3 is fixed to the bracket by bolts, which ensures the stability of the rear heating assembly 3, reduces vibration and noise, and this installation method facilitates later maintenance and repair; installing it under the front seats also saves interior space.

[0034] In another implementation, please refer to Figure 1Water pump 9 is installed on the inlet pipe 11; because the coolant entering the engine core is far from the cooling pipe 1, the design of water pump 9 ensures that the cold coolant of the engine core can flow smoothly back into the engine's cooling pipe 1 after flowing out.

[0035] In other implementations, such as Figure 3 As shown, a specific control circuit structure for the rear heating assembly 3 of this automotive heating system is provided. Those skilled in the art can also use other circuit control methods, which will not be described in detail here.

[0036] In summary, this utility model, by installing a rear heater assembly 3 under the front seats of a car, connecting a liquid outlet branch pipe 4 to the liquid outlet pipe 12, and a liquid inlet branch pipe 5 to the liquid inlet pipe 11, allows hot coolant flowing from the cooling pipe 1 to enter the front core 21 and the rear core respectively through the liquid outlet pipe 12 and the liquid outlet branch pipe 4. The front fan 22 and the rear fan blow the heat from the front core 21 and the rear core to the people sitting in the front and rear seats. The cooled coolant then flows back into the cooling pipe 1 through the liquid inlet pipe 11 and the liquid inlet branch pipe 5. On the one hand, compared to directly relying on the front heater vents or using a single centrifugal fan connected to the air duct to guide the warm air from the front heater vents, this design offers advantages over other methods. Compared to existing technologies for rear-seat vehicles, this automotive heating system offers superior heating performance, meeting the comfort requirements of users not only in low-temperature winter environments but also in extremely cold conditions. Furthermore, by utilizing the hot coolant in the engine cooling pipe 1 to provide heat, it simultaneously warms the vehicle interior while reducing engine temperature, thus saving energy. Compared to adding a separate heating device, it saves interior space. The close integration of the cooling pipe 1 and the heating system's hot water circuit ensures system stability and reliability, reduces the probability of malfunctions, and improves the overall vehicle's durability and freeze resistance; it achieves four benefits in one go. Therefore, this invention effectively overcomes the shortcomings of existing technologies and possesses high industrial application value.

[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
