Description

Technical Field

[0001] This utility model belongs to the field of automotive air conditioning technology, specifically relating to a heating and cooling radiator. Background Technology

[0002] The radiator is an indispensable component of a car's water-cooled engine cooling system. Through the internal circulation of coolant within the radiator's flat tubes and the forced convection heat exchange created by the external fan, a large amount of heat is removed, allowing the engine to operate normally under common conditions and preventing it from becoming too cold or too hot. It also acts as a heat exchanger, providing warm air to the vehicle interior and improving comfort. Heating and cooling radiators, used for both heating and cooling, are mostly separate units on the market. These not only make the equipment complex but also fail to quickly raise or lower the temperature inside the car. Utility Model Content

[0003] This utility model provides a heating and cooling radiator, which aims to solve the technical problem that current technology cannot quickly heat up or cool down the interior temperature of a car.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A heating and cooling radiator is provided, comprising a housing, a water tank, an air inlet fin, a fan, and a control system. The housing has a first chamber and a second chamber, which are interconnected. An air outlet is located on the top of the second chamber. The water tank is located within the first chamber, with its inlet and outlet pipes passing through the bottom of the housing. The air inlet fin is located on the outer wall of the housing and is arranged parallel to the water tank. The fan is located within the second chamber, with its outlet pipe connected to the air outlet of the housing. The control system is signal-connected to both the water tank and the fan.

[0005] In one possible implementation, the housing is further provided with a support, which is vertically arranged inside the housing. The support is used to isolate the first chamber and the second chamber. Both ends of the support are detachably connected to the inner sidewall of the housing, and the support is provided with notches.

[0006] In one possible implementation, the tank body is further provided with a partition, which is connected to the support, and the partition and the support form a receiving space for accommodating the water tank.

[0007] In one possible implementation, the housing is further provided with a filter screen located on the outside of the air inlet fin, the filter screen being used to filter the air.

[0008] In one possible implementation, the filter screen is connected to the housing via a detachable connection structure.

[0009] In one possible implementation, the detachable connection structure is a snap-fit ​​structure, a bolt connection structure, or a pin connection structure.

[0010] In one possible implementation, mounting claws are provided at each of the four corners of the housing.

[0011] In one possible implementation, the fan is a brushless fan.

[0012] In one possible implementation, a temperature sensor is also included, which is signal-connected to the control system.

[0013] In one possible implementation, the bottom of the housing is also provided with a drain pipe, which is connected to the first chamber.

[0014] This embodiment provides a heating and cooling radiator. Compared with the prior art, the radiator includes a housing, a water tank, air inlet fins, a fan, and a control system. When the fan is activated and the control system detects a change in the temperature inside the car, requiring cooling, cold water is injected into the water tank. Air enters the first chamber through the air inlet fins and is then cooled by the water tank. The cooled air is then discharged into the car through the fan's outlet pipe, thus achieving the effect of cooling the car's interior. Conversely, when it is necessary to raise the temperature inside the car, hot water is injected into the water tank. Air enters the first chamber through the air inlet fins and is then heated by the water tank. The heated air is then discharged into the car through the fan's outlet pipe, thus achieving the effect of raising the temperature inside the car. The heating and cooling of the water tank makes the air from the ventilation fan more humid than the air heated by heating elements such as electric heating wires. This application only needs to control the injection of cold or hot water into the water tank to control the air temperature, thereby solving the technical problem of the inability to quickly heat up or cool down the car interior due to the separate heating and cooling design in the existing market.

[0025] Please refer to the following: Figure 1 and Figure 2The present invention provides a heating and cooling radiator. The heating and cooling radiator includes a housing 1, a water tank 2, an air inlet fin 3, a fan, and a control system. The housing 1 has a first chamber 11 and a second chamber 12, which are interconnected. An air outlet 121 is located on the top of the second chamber 12. The water tank 2 is located in the first chamber 11, and its inlet pipe 21 and outlet pipe 22 are both located at the bottom of the housing 1. The air inlet fin 3 is located on the outer wall of the housing 1 and is arranged parallel to the water tank 2. The fan is located in the second chamber 12, and its outlet pipe is connected to the air outlet 121 of the housing 1. The control system is signal-connected to the water tank 2 and the fan, respectively.

[0026] Water tank 2 is equipped with a circulation system and heat sinks. The circulation system efficiently delivers water from water tank 2 to the heat sinks and allows for rapid switching between hot and cold water. The heat sinks, located on the side of water tank 2, increase the surface area of ​​contact between the water tank 2 and the air. The circulation system delivers either cold or hot water to the heat sinks, where it exchanges heat with the incoming air, thus rapidly heating or cooling the air. Water in water tank 2 is injected through inlet pipe 21 and discharged through outlet pipe 22.

[0027] This embodiment provides a heating and cooling radiator. Compared with the prior art, the heating and cooling radiator includes a housing 1, a water tank 2, an air inlet 3, a fan, and a control system. When the fan is turned on and the control system detects a change in the temperature inside the car, and cooling is required, cold water is injected into the water tank 2. Air enters the first chamber 11 through the air inlet 3 and is then cooled by the water tank 2. The cooled air is then discharged into the car through the fan's outlet pipe, thus achieving the effect of cooling the car's interior. Conversely, when heating is required, hot water is injected into the water tank 2. Air enters the first chamber 11 through the air inlet 3 and is then heated by the water tank 2. The heated air is then discharged into the car through the fan's outlet pipe, thus achieving the effect of heating the car's interior. After the water tank 2 heats up and cools down, the air from the ventilation fan becomes more humid than the air heated by heating elements such as electric heating wires. This application only needs to control the injection of cold or hot water into the water tank 2 to control the air temperature, thereby solving the technical problem in the existing market where the separate heating and cooling design cannot quickly heat up or cool down the room temperature inside the car.

[0028] In some embodiments, in one possible implementation, the housing 1 is further provided with a support 4, which is vertically arranged inside the housing 1. The support 4 is used to isolate the first chamber 11 and the second chamber 12. The two ends of the support 4 are detachably connected to the inner sidewall of the housing 1, and the support 4 is provided with a notch 41.

[0029] The bracket 4 not only separates the first chamber 11 and the second chamber 12, but also connects the corresponding side walls of the housing 1 together, thereby increasing the overall connection strength of the housing 1. Simultaneously, the bracket 4 has a notch 41 corresponding to the water tank 2, allowing air entering from the air intake to flow into the second chamber 12 after being heated or cooled by the water tank 2. From there, the air is discharged into the vehicle's interior by a fan for temperature regulation.

[0030] The two ends of the bracket 4 are connected to the inner side wall of the box 1 through a detachable connection structure, which facilitates the disassembly and installation of the bracket 4.

[0031] Specifically, the detachable connection structure can be a snap-fit ​​structure, a bolt connection structure, or a pin connection structure.

[0032] Based on the above embodiment, the housing 1 is further provided with a partition 5, which is connected to the support 4. The partition 5 and the support 4 together form a receiving space for accommodating the water tank 2. When the water tank 2 is placed in the receiving space jointly formed by the partition 5 and the support 4, it can prevent the water tank 2 from moving when the vehicle is bumpy, thus avoiding damage to the equipment.

[0033] Specifically, the water tank 2 and the bracket 4 are connected and fixed by bolts. At the same time, the partition 5 is also provided with through holes, which are opened in correspondence with the notch 41, so as to facilitate the air to pass through the water tank 2 for temperature regulation.

[0034] In some other embodiments, since the air vents contain many impurities and the air quality cannot be guaranteed in the environment where the car is driving, a filter screen 13 is also provided on the housing 1. The filter screen 13 is located on the outside of the air inlet 3 and is used to filter the air.

[0035] Specifically, the filter screen 13 is connected to the housing 1 via a detachable connection structure.

[0036] Filter 13 is located at the air inlet and effectively filters incoming dust, ensuring clean air entering the radiator. Filter 13 is made of high-efficiency filter material, offering excellent filtration performance and a long service life, providing a fresh air environment for vehicle occupants. Compared to ordinary filters, this filter 13 has finer pores and stronger filtration capabilities, effectively removing fine particulate matter and harmful gases from the air, providing a healthier air environment for vehicle occupants.

[0037] Furthermore, the detachable connection structure can be a snap-fit ​​structure, a bolt connection structure, or a pin connection structure.

[0038] The use of snap-fit, bolt-fit, or pin-fit structures facilitates the disassembly and installation of the filter screen 13, thereby making it easier to clean the filter screen 13.

[0039] In the above embodiment, mounting claws 14 are provided on all four corners of the housing 1. The mounting claws 14 are provided for connection and fixation with the car.

[0040] In other embodiments, the fan is a brushless fan.

[0041] A brushless fan is a type of fan that uses a brushless DC motor (BLDCM). The motor of a brushless fan consists of a permanent magnet rotor, a multi-pole winding stator, and a position sensor. Its working principle involves electronic control circuitry detecting the rotor position and commutating the current in the stator windings in a specific sequence, thereby generating a rotating magnetic field that drives the permanent magnet rotor to rotate, which in turn drives the fan impeller. The position sensor commutates the current in the stator windings in a specific sequence according to changes in the rotor position. The operating voltage of the stator windings is provided by an electronic switching circuit controlled by the position sensor output.

[0042] Brushless fans have the following advantages:

[0043] High efficiency and energy saving: The brushless fan uses permanent magnet excitation, which eliminates the loss generated by the excitation current of the induction motor; at the same time, it operates in synchronous mode, eliminating the frequency loss of the rotor core of the induction motor. The operating efficiency is much higher than that of the induction motor, and the efficiency improvement is more obvious for small capacity motors.

[0044] High power factor: Its excitation magnetic field does not require reactive current from the power grid, and its power factor is much higher than that of an induction motor.

[0045] Good speed regulation performance and simple control: Compared with the frequency conversion speed regulation of induction motors, the speed regulation control of brushless DC motors is not only simple, but also has better speed regulation performance.

[0046] High reliability: By eliminating the slip rings and brushes used for excitation, the structure is greatly simplified, which not only improves the manufacturability of the motor, but also greatly enhances the mechanical reliability of the motor operation and increases its lifespan.

[0047] Low mechanical noise: There is no friction and electrical sparks between the brushes and the commutator, resulting in smoother operation and lower mechanical and electromagnetic noise.

[0048] In summary, brushless fans, employing advanced PWM control technology, can precisely adjust the fan speed to achieve efficient air circulation. The unique blade design of brushless fans effectively reduces noise levels while ensuring large airflow, providing a quiet environment inside the vehicle.

[0049] Furthermore, the radiator also includes a temperature sensor, which is connected to the control system. The temperature sensor is located on the air inlet fin 3. This high-precision sensor can collect the intake air temperature in real time and feed the data back to the control system. Based on the feedback from the temperature sensor, the control system precisely adjusts the speed of the brushless fan and the water supply to the water tank 2 to accurately control the interior temperature. Through real-time monitoring and adjustment, the interior temperature is always maintained within the user-set comfort range. This temperature sensor has higher accuracy and faster response speed, enabling it to more accurately sense changes in the interior temperature and thus adjust the radiator's operating status promptly.

[0050] High-precision temperature sensors can be platinum resistance temperature sensors, thermocouple temperature sensors, thermistor temperature sensors, or digital temperature sensors.

[0051] The following is a partial introduction to the models and functions of platinum resistance temperature sensors.

[0052] PT100: A widely used high-precision temperature sensor with a resistance of 100Ω at 0℃. According to Chinese standards, the accuracy of a Class II platinum resistance thermometer is ±0.3℃, and the accuracy of a Class I platinum resistance thermometer is ±0.15℃.

[0053] PT1000: The resistance value is 1000Ω at 0℃. The measurement accuracy is very high, reaching high precision levels such as ±0.1℃, ±0.2℃, and ±0.5℃. The resistance value has a linear relationship with temperature change, good stability, and strong anti-interference ability.

[0054] Specifically, the bottom of the box 1 is also provided with a drain pipe 15, which is connected to the first chamber 11.

[0055] When moisture in the air comes into contact with the water tank 2, it condenses into small water droplets upon cooling. These droplets then converge into a water flow within the first chamber 11 and are eventually discharged through the drain pipe 15. This prevents water from accumulating inside the tank 1, which could corrode the equipment inside, shorten its service life, and increase safety hazards.

[0056] Furthermore, a water collection trough is provided at the bottom of the housing 1. This trough collects condensate generated in the radiator and drains it through 15 drain pipes. The trough's design effectively prevents condensate overflow, keeping the equipment dry and clean, and avoiding damage to other components inside the vehicle. This trough has a larger capacity and better drainage performance, enabling more efficient collection and drainage of condensate, ensuring the normal operation of the equipment.

[0057] Based on the above embodiment, the housing 1 is provided with two air outlets 121. The two air outlets 121 can more quickly replace the air inside the car.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
