Description

Technical Field

[0001] This utility model relates to the field of heat dissipation performance testing technology, and in particular to a device for testing the performance of automotive radiator fans. Background Technology

[0002] The radiator fan is a crucial component of a car's cooling system. Its primary function is to enhance the radiator's heat dissipation capacity through forced ventilation. When the engine coolant temperature rises to a certain level, the fan's control circuit is activated, and the fan begins to rotate. An electric motor drives the fan blades, blowing air from the front or rear of the radiator towards the radiator core. The cool air flows over the fins and cooling pipes on the radiator core's surface, carrying away heat from the coolant and lowering its temperature, thus ensuring the engine operates within a suitable temperature range.

[0003] A utility model application with application number 202121414710.0 discloses a fan performance testing fixture. By placing the fan in the corresponding position on the fixture body, and placing the fan motor housing inside a fixed support column, an electric-pneumatic combination is used to retract a telescopic cylinder, causing the fixed support column to retract and press against the outer wall of the fan motor housing, thus fixing it in place. Controlled by a solenoid valve, the telescopic cylinder extends, and the fixed support column is no longer in contact with the fan motor housing, releasing the fan. The combination of electric and pneumatic control allows for better automation and facilitates automated fan performance testing. The fan is placed horizontally, facilitating vertical placement and allowing for convenient placement or movement using a robotic arm. During fan installation, simply placing the fan in the appropriate position is sufficient, requiring minimal operation and saving work during installation and disassembly.

[0004] However, the aforementioned fan performance testing fixture cannot simulate the airflow and temperature environment inside a car during testing, which may result in errors between the data measured on the testing fixture and the actual situation. Furthermore, when the fan speed is too high during testing, the fan is prone to detaching from the fan holder and flying off, posing a certain safety hazard. Therefore, this utility model proposes a car radiator fan performance testing device to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide a vehicle radiator fan performance testing device. This device uses an electric telescopic rod to extend and lower an environmental simulation chamber to cover the fan, which is then heated by an electric heating element to increase the temperature, simulating the temperature environment of a vehicle during operation and improving testing accuracy. Simultaneously, the environmental simulation chamber provides protection, preventing the fan from flying out. A motor drives a drive wheel to rotate, which in turn causes a rotating plate to rotate. Adjusting the size of the intersection of the first and second ventilation openings simulates the airflow environment inside the vehicle, further improving testing accuracy.

[0006] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: a vehicle radiator fan performance testing device, including a testing platform, an ambient temperature simulation mechanism, an ambient airflow simulation mechanism, and a fan clamping mechanism. The ambient temperature simulation mechanism includes a bracket, an electric telescopic rod, an ambient simulation chamber, electric heating tubes, a temperature sensor, and a sealing and fitting mechanism. A bracket is fixedly provided in the middle of the testing platform, and an electric telescopic rod is symmetrically fixedly provided above the bracket. An ambient simulation chamber is fixedly provided at the telescopic end of the electric telescopic rod. Electric heating tubes are arranged and fixedly provided inside the ambient simulation chamber. A temperature sensor is fixedly provided in the top middle of the ambient simulation chamber. A sealing and fitting mechanism is fixedly provided in the middle of the testing platform. An ambient airflow simulation mechanism is symmetrically connected to both sides of the ambient simulation chamber. A fan clamping mechanism is provided on the sealing and fitting mechanism.

[0007] A further improvement is that the bottom of the environmental simulation chamber is open, and multiple sets of electric heating tubes are arranged.

[0008] A further improvement is that the sealing and bonding mechanism includes a sealing platform, a fixing plate, and a rubber strip. The sealing platform is fixedly installed in the middle of the testing platform, and the fixing plate is fixedly installed on the four sides of the sealing platform. The rubber strip is fixedly installed around the outside of the fixing plate, and the rubber strip corresponds to the upper and lower positions of the inner wall of the environmental simulation chamber.

[0009] A further improvement is made in that: the environmental airflow simulation mechanism includes a ventilation chamber, a fixed plate, a rotating plate, a first vent, a second vent, a motor, and a drive wheel. The ventilation chambers are symmetrically fixed on both sides of the environmental simulation chamber. The ventilation chambers are open on both sides and connected to the environmental simulation chamber. A fixed plate is fixedly installed in the middle of the ventilation chamber. A rotating plate is rotatably installed on the outside of the fixed plate. A first vent is circumferentially opened on the fixed plate. A second vent is circumferentially opened on the rotating plate. A motor is fixedly installed above the ventilation chamber. A drive wheel is rotatably installed above the ventilation chamber.

[0010] A further improvement is that the output end of the motor is connected to the drive wheel, and the drive wheel is in contact with and rubs against the outer side of the rotating plate.

[0011] Further improvements are made in that: the fan clamping mechanism includes a clamping chamber, an extension frame, a spring, a slide groove, a limiting plate, a wire hole, and a heat dissipation hole. The clamping chamber is fixedly provided in the middle of the closed platform. An extension frame is symmetrically fixedly provided on one side of the clamping chamber. A spring is fixedly provided in the middle of the extension frame. Slide grooves are symmetrically provided between the extension frames. A limiting plate is slidably provided between the slide grooves. A wire hole is provided on the other side of the clamping chamber. Heat dissipation holes are symmetrically arranged in the front and back of the clamping chamber.

[0012] A further improvement is that the clamping chamber is hollow inside and open on one side, and the outer side of the limiting plate is fixedly connected to the spring.

[0013] The beneficial effects of this utility model are as follows: This utility model uses an electric telescopic rod to extend and lower the environmental simulation chamber to cover the fan, and then the electric heating tube heats up the temperature to simulate the temperature environment when the car is working, thereby improving the detection accuracy. At the same time, the environmental simulation chamber also serves as a protective measure to prevent the fan from flying out. The motor drives the drive wheel to rotate, and the friction drives the rotating plate to rotate. By adjusting the size of the intersection of the first ventilation port and the second ventilation port, the airflow environment inside the simulated car can be adjusted, thereby improving the detection accuracy.

[0020] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0021] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, this embodiment provides a vehicle radiator fan performance testing device, including a testing platform 1, an ambient temperature simulation mechanism, an ambient airflow simulation mechanism, and a fan clamping mechanism. The ambient temperature simulation mechanism includes a support 2, an electric telescopic rod 3, an ambient simulation chamber 4, electric heating tubes 5, a temperature sensor 6, and a sealing and fitting mechanism. The support 2 is fixedly mounted in the middle of the testing platform 1, and the electric telescopic rod 3 is symmetrically fixedly mounted above the support 2. The ambient simulation chamber 4 is fixedly mounted at the telescopic end of the electric telescopic rod 3. Electric heating tubes 5 are arranged and fixedly mounted inside the ambient simulation chamber 4. The bottom of the ambient simulation chamber 4 is open, and multiple sets of electric heating tubes 5 are arranged. A temperature sensor 6 is fixedly installed in the middle of the top of the simulation chamber 4. When it is necessary to simulate the ambient temperature when the interior of a car is working, the electric telescopic rod 3 extends and drives the simulation chamber 4 to descend and cover the fan to form a relatively closed environment. At the same time, the electric heating tube 5 is energized to heat up and raise the internal temperature of the simulation chamber 4 to simulate the temperature when the car is working, so that the performance data obtained by the test is closer to reality. This solves the problem that it is impossible to simulate the internal temperature environment of a car during the test. A sealing and bonding mechanism is fixedly installed in the middle of the test table 1. The environmental airflow simulation mechanism is symmetrically connected on both sides of the simulation chamber 4. A fan clamping mechanism is installed on the sealing and bonding mechanism.

[0022] The sealing and bonding mechanism includes a sealing platform 7, a fixing plate 8, and a rubber strip 9. The sealing platform 7 is fixedly installed in the middle of the testing platform 1, and the fixing plate 8 is fixedly installed on the four sides of the sealing platform 7. The rubber strip 9 is fixedly installed around the outside of the fixing plate 8. The rubber strip 9 corresponds to the upper and lower positions of the inner wall of the environmental simulation chamber 4. When the environmental simulation chamber 4 descends, it is sealed with the sealing platform 7 to form a closed environment. At the same time, the rubber strip 9 adheres to the inner wall of the environmental simulation chamber 4 to improve the sealing performance and effectively reduce the interference of the external environment on the test results.

[0023] The environmental airflow simulation mechanism includes a ventilation chamber 10, a fixed plate 11, a rotating plate 12, a first ventilation port 13, a second ventilation port 14, a motor 15, and a drive wheel 16. The ventilation chambers 10 are symmetrically fixed on both sides of the environmental simulation chamber 4. The ventilation chambers 10 are open on both sides and connected to the environmental simulation chamber 4. The fixed plate 11 is fixedly fixed in the middle of the ventilation chamber 10. The rotating plate 12 is rotatably fixed on the outside of the fixed plate 11. The first ventilation port 13 is circumferentially opened on the fixed plate 8. The second ventilation port 14 is circumferentially opened on the rotating plate 12. The motor 15 is fixedly fixed above the ventilation chamber 10. The drive wheel 16 is rotatably installed in the upper part of the ventilation chamber 10. The output end of the motor 15 is connected to the drive wheel 16. The drive wheel 16 is in contact with and rubs against the outside of the rotating plate 12. When different airflow intake volumes need to be simulated, the motor 15 drives the drive wheel 16 to rotate, which in turn drives the rotating plate 12 to rotate. The ventilation volume can be quickly and easily adjusted by using the first ventilation port 13 and the second ventilation port 14 to overlap. The ventilation volume is maximized when the first ventilation port 13 and the second ventilation port 14 overlap.

[0024] The fan clamping mechanism includes a clamping chamber 17, an extension frame 18, a spring 19, a slide 20, a limiting plate 21, a wire hole 22, and a heat dissipation hole 23. The clamping chamber 17 is fixedly mounted in the middle of the enclosed platform 7. An extension frame 18 is symmetrically fixed to one side of the clamping chamber 17, with a spring 19 fixedly mounted in the middle of the extension frame 18. Slides 20 are symmetrically arranged vertically between the extension frames 18, and a limiting plate 21 slides between the slides 20. A wire hole 22 is opened on the other side of the clamping chamber 17. The clamping chamber 17 is symmetrically arranged with heat dissipation holes 23. The interior of the clamping chamber 17 is hollow and open on one side. The outer side of the limiting plate 21 is fixedly connected to the spring 19. Before testing, the fan drive motor 15 is placed into the clamping chamber 17 through the opening. The limiting plate 21 slides and merges along the slide groove 20 under the elastic push of the spring 19 to form a closed clamp. The fan rotating end extends out from between the limiting plates 21 and rotates. The wire hole 22 facilitates the connection of the power supply wire. The heat dissipation hole 23 facilitates the heat dissipation of the fan drive end during testing.

[0025] When testing the performance of this automotive radiator fan, the fan drive end is inserted into the clamping chamber from one side. A spring pushes the limiting plate to slide along the slide groove and clamp and limit it. A wire is inserted into the wire hole to drive the fan to rotate. When it is necessary to simulate the internal temperature of the car, the electric telescopic rod extends and drives the environmental simulation chamber to descend and cover the fan, which then contacts and seals the closed platform. A rubber strip is attached to the inner wall of the environmental simulation chamber to seal it. When the fan rotates for testing, the airflow flows in from one ventilation chamber and then flows out from the other ventilation chamber. The electric heating tube is energized to heat the internal temperature of the environmental simulation chamber to simulate the working environment temperature of the car. When it is necessary to simulate the internal airflow environment of the car, the motor drives the drive wheel to rotate, and the friction drives the rotating plate to rotate in the ventilation chamber. The size of the staggered opening between the first and second ventilation ports is used to adjust the simulated airflow environment.
