Description

Technical Field

[0001] This application relates to the field of automotive engine cooling technology, and in particular to a radiator assembly with intelligent temperature control. Background Technology

[0002] The radiator assembly is a key component of a car's cooling system. It typically includes the radiator core, upper reservoir, lower reservoir, and radiator fan. Its working principle is as follows: when the engine is running, the coolant circulates inside the engine, absorbing the heat generated and keeping the engine temperature within its normal operating range. The hot coolant flows through the water pipes into the upper reservoir of the radiator, then flows downwards into the radiator core. At this time, the radiator fan operates, causing air to flow rapidly across the radiator core, carrying away the heat from the coolant and lowering its temperature. The cooled coolant then flows out of the radiator core into the lower reservoir, where it re-enters the engine for circulation. This cycle repeats, achieving the goal of cooling the engine.

[0003] In related technologies, traditional car engine radiators typically use mechanical fans for cooling, which cannot precisely control the coolant temperature, resulting in some energy waste.

[0004] Therefore, we propose a radiator assembly with intelligent temperature control to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a radiator assembly with intelligent temperature control, which can achieve efficient, precise and intelligent control of the coolant temperature in the automotive cooling system.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a radiator assembly with intelligent temperature control, comprising a radiator housing, a radiator core, a radiator fan, an upper water tank, and a lower water tank installed on a vehicle. The radiator core is fixedly installed inside the radiator housing, the radiator fan is detachably installed and fixed on the rear side wall of the radiator housing, the upper water tank is fixedly installed on the top of the radiator housing, and the lower water tank is fixedly installed on the bottom of the radiator housing. The water inlet end of the radiator core is connected to the water outlet end of the upper water tank, and the water outlet end of the radiator core is connected to the water inlet end of the lower water tank. An inlet water temperature sensor is fixedly installed at the water outlet end of the upper water tank, and an outlet water temperature sensor is fixedly installed at the water inlet end of the lower water tank.

[0007] By adopting the above technical solution, the inlet water temperature sensor and the outlet water temperature sensor can monitor the temperature change of the coolant at both ends of the radiator core in real time.

[0008] A further provision of this application is that the number of the radiator core and the cooling fan are both set to two, and the two cooling fans are respectively adapted to the corresponding radiator core.

[0009] By adopting the above technical solutions, the heat dissipation area and air volume can be increased, which can more effectively dissipate the large amount of heat generated during the operation of the car, ensure that key components such as the engine work within a suitable temperature range, ensure that the water temperature of the whole vehicle cooling system is within a suitable range, reduce the risk of performance degradation or failure due to overheating, and ensure the stable operation of the car.

[0010] A further feature of this application is that the radiator core includes multiple cooling pipes, each of which is fixedly fitted with a number of heat sink fins.

[0011] By adopting the above technical solution, the heat exchange efficiency is enhanced, enabling the coolant to quickly transfer heat to the heat sink when flowing through the cooling pipe, and then the airflow generated by the cooling fan carries away the heat.

[0012] A further provision of this application is that one end of each of the multiple cooling pipes is connected to the outlet end of the upper water tank via a pipe, and one end of each of the multiple cooling pipes is connected to the inlet end of the lower water tank via a pipe.

[0018] A further feature of this application is that a controller is installed on the radiator housing, and the inlet water temperature sensor, the outlet water temperature sensor, and the cooling fan are all electrically connected to the controller.

[0019] By adopting the above technical solution, the inlet and outlet water temperature sensors monitor the temperature changes of the coolant at both ends of the radiator core and transmit the data to the controller. Based on this temperature information, the controller can precisely adjust the speed of the radiator fan. When the temperature rises, the radiator fan speed is appropriately increased to enhance the heat dissipation effect; when the temperature drops to a suitable range, the speed is reduced accordingly. This ensures the heat dissipation requirements are met while avoiding unnecessary energy consumption and noise generation, achieving intelligent and precise temperature control and optimizing the overall energy efficiency of the vehicle.

[0032] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] See Figure 1 , Figure 2 and Figure 3 This application provides a radiator assembly with intelligent temperature control, including a radiator housing 1, a radiator core 2, a radiator fan 3, an upper water tank 4, and a lower water tank 5, all mounted on a vehicle. The radiator core 2 is fixedly installed inside the radiator housing 1. The radiator fan 3 is detachably mounted on the rear side wall of the radiator housing 1. The upper water tank 4 is fixedly installed on the top of the radiator housing 1, and the lower water tank 5 is fixedly installed on the bottom of the radiator housing 1. The inlet end of the radiator core 2 is connected to the outlet end of the upper water tank 4, and the outlet end of the radiator core 2 is connected to the inlet end of the lower water tank 5.

[0034] An inlet water temperature sensor 6 is fixedly installed at the outlet end of the upper water tank 4, and an outlet water temperature sensor 7 is fixedly installed at the inlet end of the lower water tank 5. The number of radiator core 2 and cooling fan 3 is set to two. The two cooling fans 3 are respectively adapted to the corresponding radiator core 2. The radiator core 2 includes multiple cooling pipes, and several heat dissipation fins are fixedly installed on each of the multiple cooling pipes. One end of each of the multiple cooling pipes is connected to the outlet end of the upper water tank 4 through a pipe, and one end of each of the multiple cooling pipes is connected to the inlet end of the lower water tank 5 through a pipe.

[0035] In this embodiment, the cooling fan 3 is fixed to the rear side wall of the radiator housing 1 by screws.

[0036] In this embodiment, the radiator fan 3 is a brushless electronic fan. It should be noted that the speed of the brushless electronic fan is directly proportional to the power supply voltage. Therefore, the speed of the radiator fan 3 can be adjusted by changing the input voltage. A controller 8 is installed on the radiator housing 1. The controller 8 is an ATS controller. The inlet water temperature sensor 6, the outlet water temperature sensor 7, and the radiator fan 3 are all electrically connected to the controller 8. The inlet water temperature sensor 6 and the outlet water temperature sensor 7 can monitor the temperature changes of the coolant at the inlet and outlet ends of the radiator core 2 in real time. The temperature changes of the coolant at the inlet and outlet ends of the radiator core 2 monitored by the inlet water temperature sensor 6 and the outlet water temperature sensor 7 are transmitted to the controller 8. Based on this temperature information, the controller 8 can accurately control the speed of the radiator fan 3. When the temperature rises, the speed of the radiator fan 3 is appropriately increased to enhance the heat dissipation effect; when the temperature drops to a suitable range, the speed is reduced accordingly. This ensures the heat dissipation requirements are met while avoiding unnecessary energy consumption and noise generation, realizing intelligent and precise temperature control and optimizing the overall energy utilization efficiency of the vehicle.

[0037] With the above structure, the working principle of the radiator assembly with intelligent temperature control provided in this application is as follows: When the car engine is working, it generates heat. The coolant absorbs heat in the engine and its temperature rises. The high-temperature coolant first flows into the upper water tank 4 through the pipe, and then enters multiple cooling pipes of the radiator core 2 from its outlet end through the pipe. During the flow of the high-temperature coolant in the cooling pipe, the heat in the high-temperature coolant is transferred to the heat sink fins mounted on the cooling pipe. At this time, the temperature of the heat sink fins rises. The air generated by the operation of the radiator fan 3 makes the air flow quickly through the radiator core 2, which can carry away the heat in the coolant and achieve the effect of cooling the coolant entering the radiator core 2. After that, the cooled coolant flows out from the outlet end of the radiator core 2 and enters the lower water tank 5 through the pipe. The cooled coolant in the lower water tank 5 then flows back into the cooling system of the car engine to continue to absorb heat in the engine, thus completing one cycle in the radiator. During the entire cycle, the coolant continuously carries away the heat generated by the engine and plays the role of cooling the engine.

[0038] In this embodiment, it should be further explained that the controller 8 is also electrically connected to the car engine and the car air conditioner. When the car air conditioner is started, the controller 8 receives a signal and immediately sends a PWM signal to the radiator fan 3 to control the start, stop and speed of the radiator fan 3. The controller 8 controls the start, stop and speed of the radiator fan 3 by reading the water temperature from the inlet and outlet temperature sensors of the radiator core 2. At the same time, the controller 8 can also read the fault feedback information of the radiator fan 3 and feed it back to the whole vehicle. The specific control method is as follows:

[0039] When the outlet water temperature of the radiator core 2 monitored by the outlet water temperature sensor 7 reaches 45℃, the controller 8 controls the two cooling fans 3 to start working. When the outlet water temperature of the radiator core 2 monitored by the outlet water temperature sensor 7 reaches 55℃, the controller 8 controls the two cooling fans 3 to work at full speed. The specific temperature control speed table for interval speed adjustment is as follows.

[0040]

[0041]

[0042] When the inlet water temperature of the radiator core 2 monitored by the inlet water temperature sensor 6 reaches 65°C, the controller 8 controls the two cooling fans 3 to work at full speed immediately.

[0043] When the car engine and air conditioning are on, if the outlet water temperature of the radiator core 2 monitored by the outlet water temperature sensor 7 does not reach the required 45%, the two radiator fans 3 will operate at a fixed speed of 45%.

[0044] When the car engine and air conditioner are on, if the outlet water temperature of the radiator core 2 monitored by the outlet water temperature sensor 7 exceeds the requirement by 45%, the temperature control tachometer in the figure above shall be used as the reference.

[0045] When the car air conditioner is turned on and then off, if the temperature of the coolant at the inlet and outlet ends of the radiator core 2, as monitored by the inlet water temperature sensor 6 and the outlet water temperature sensor 7, is no longer within the operating temperature range, the two cooling fans 3 will stop after a delay of 30 seconds.

[0046] When the inlet water temperature sensor 6 and the outlet water temperature sensor 7 are damaged or lose their signals, the controller 8 controls the two cooling fans 3 to run at full speed.

[0047] In this embodiment, a wind shield is detachably installed on the outside of the cooling fan 3. The wind shield can protect the cooling fan 3 from impacts or interference from external objects. At the same time, its detachable feature also facilitates the inspection and maintenance of the cooling fan 3, extending the service life of the cooling fan 3 and the entire heat sink assembly.

[0048] In this embodiment, a coolant filling port is provided on the top of the upper water tank 4. A plug is installed in the internal thread of the coolant filling port. The coolant filling port is designed to facilitate the addition of coolant when needed. The plug is connected by a thread to ensure the sealing of the filling port, prevent coolant leakage, and ensure the normal liquid level and circulation of the radiator assembly.
