Description

Technical Field

[0001] The utility model is applied to the technical field of vehicle heat dissipation, and particularly relates to a top-mounted active radiator structure. Background Art

[0002] When the drive motor of a new energy bus is running, there are various losses inside, such as winding loss caused by current in the conductor, core loss caused by alternating magnetic field in the core, mechanical loss caused by ventilation and mechanical friction, etc. These losses are converted into heat, which spreads to the surrounding through the medium, causing the temperature of the internal components to rise. When the temperature exceeds a certain value, the coil insulation will fail and the permanent magnet will be permanently damaged. To control the temperature of each component of the drive motor within the allowable range, on the one hand, it is necessary to reduce losses and reduce its heat generation, and on the other hand, it is necessary to improve its heat dissipation capacity. For most new energy bus models, a liquid cooling system will be designed for the drive motor. The liquid cooling system mainly consists of a radiator, an electronic hydraulic pump, an expansion kettle, cooling pipes and components that need cooling and heat dissipation. Generally, the air inlet of the radiator is installed on the side of the vehicle body, and the air outside the vehicle body is forced in through the cooling fan of the radiator. At the same time, the air flows through the heat sink on the main water tank of the radiator, taking away the heat on the heat sink, thereby cooling the coolant. The tail section of some new energy buses with short rear overhang has compact space, and the radiator of the drive motor cooling system must be installed on the roof. If the traditional radiator is still installed in the original upright state, it will increase the height of the vehicle and also increase the wind resistance coefficient of the vehicle. If a roof-mounted active radiator structure with simple and compact structure, active air intake function, and effective reduction of vehicle noise and energy consumption can be designed, the above problems can be solved. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a top-mounted active radiator structure which has a simple and compact structure, an active air intake function and can effectively reduce the noise of the whole vehicle and reduce the energy consumption of the whole vehicle.

[0004] The technical solution adopted by the utility model is as follows: the utility model includes a fixed bracket, a heat dissipation water tank, a front air flow component, a side air inlet plate, a fan rectifying component and a rear air shield, a plurality of the fixed brackets are respectively connected to both sides of the heat dissipation water tank, the front air flow component includes a front frame and an air inlet mesh plate, the front frame is connected to the air inlet ends of a plurality of the fixed brackets, the air inlet mesh plate is connected to the front frame, the rear air shield is respectively connected to the fixed ends of a plurality of the fixed brackets and the fixed end of the heat dissipation water tank, a plurality of the side air inlet plates are respectively connected to the fixed brackets on both sides of the heat dissipation water tank, the fan rectifying component includes a heat dissipation fan and an air guide cover, the air guide cover is provided with a rectangular air inlet and a circular air outlet, the air guide cover is connected to the upper end surface of the heat dissipation water tank, the rectangular air inlet cooperates with the heat dissipation water tank, and the heat dissipation fan is connected to the circular air outlet.

[0005] Furthermore, the heat dissipation water tank includes a housing, a plurality of heat sinks, a water inlet and a water outlet. The coolant in the external cooling pipeline enters the housing through the water inlet and communicates with the external cooling pipeline through the water outlet.

[0006] Furthermore, the side air inlet plate is provided with a plurality of side air inlets, and an outward expansion guide plate is provided on one side of the plurality of side air inlets. The plurality of outward expansion guide plates expand outward at a certain angle and face the front and the outside of the vehicle and cooperate with the external airflow.

[0007] Furthermore, a flange is provided at the lower end of the rear wind shield, and the flange cooperates with the fixed end of the radiator water tank.

[0008] Furthermore, a waterproof plug-in is provided at the end of the power line of the cooling fan.

[0009] Furthermore, a plurality of fixed buffer rubber pads are provided at the bottom of the fixed bracket, and the fixed bracket cooperates with the top mounting position of the vehicle through the plurality of fixed buffer rubber pads.

[0010] The beneficial effects of the utility model are as follows: the utility model reduces the installation height while ensuring the original heat dissipation performance by redesigning the structure of the radiator, which can reduce the air resistance coefficient to a certain extent. In addition, when there is a height limit for the entire vehicle, more height space can be left for the car compartment. The cooling fan will stop working when the driving motor is working at low power consumption to reduce the energy consumption of the entire vehicle. When the driving motor is working at high power consumption, the cooling fan will work at full speed and input air through multiple wind paths on the front and sides, and a number of outward expansion guide plates are provided so that the air will actively flow into the inside of the radiator when flowing through the present invention from the outside, and at the same time, the air inside the radiator cannot actively flow out from the inside of the side air inlet plate to the outside, which has the effect of unidirectional guide, so as to improve the heat dissipation efficiency of the radiator, and make full use of the airflow through the plurality of the heat sinks to take away the heat of the cooling liquid in the heat sink, thereby effectively dissipating heat.

[0018] like Figures 1 to 7 As shown, in this embodiment, the utility model includes a fixed bracket 1, a heat sink 2, a front airflow assembly 3, a side air inlet plate 4, a fan rectifier assembly 5 and a rear air shield 6, a plurality of the fixed brackets 1 are respectively connected to both sides of the heat sink 2, the front airflow assembly 3 includes a front frame 31 and an air inlet mesh plate 32, the front frame 31 is connected to the air inlet end of the plurality of the fixed brackets 1, the air inlet mesh plate 32 is connected to the front frame 31, and the rear air shield 6 is respectively connected to the plurality of the fixed brackets The fixed end of the bracket 1 is connected to the fixed end of the heat dissipation water tank 2, and the side air inlet plates 4 are respectively connected to the fixed brackets 1 on both sides of the heat dissipation water tank 2. The fan rectifier assembly 5 includes a heat dissipation fan 51 and a guide cover 52. The guide cover 52 is provided with a rectangular air inlet 53 and a circular air outlet 54. The guide cover 52 is connected to the upper end surface of the heat dissipation water tank 2. The rectangular air inlet 53 cooperates with the heat dissipation water tank 2, and the heat dissipation fan 51 is connected to the circular air outlet 54. It can be seen that the utility model is fixed on the top of the vehicle through the fixed brackets 1. When the vehicle is started, the airflow will enter the radiator from the front airflow assembly 3 and the side air inlet plates 4 on both sides, and take away the heat through the heat dissipation fan 51.

[0019] like Figure 1 and Figure 4As shown, in this embodiment, the heat dissipation water tank 2 includes a box body 21, a plurality of heat dissipation fins 22, a water inlet 23 and a water outlet 24. The coolant in the external cooling pipeline enters the box body 21 through the water inlet 23 and communicates with the external cooling pipeline through the water outlet 24. It can be seen that the airflow takes away the coolant temperature in the box body through the plurality of heat dissipation fins 22 in the middle of the heat dissipation water tank 2, and actively draws the heat to the outside of the vehicle through the heat dissipation fan 51. The coolant communicates with the vehicle cooling pipeline through the water inlet 23 and the water outlet 24, and takes away the heat of various heating devices in the vehicle.

[0020] like Figure 1 and Figure 5 As shown, in this embodiment, the side air inlet plate 4 is provided with a plurality of side air inlets 7, and an outward expansion guide plate 8 is provided on one side of the plurality of side air inlets 7. The plurality of outward expansion guide plates 8 expand outward at a certain angle and face the front and the outside of the vehicle and cooperate with the external airflow. It can be seen that when the vehicle is moving forward, when the air flows through the side air inlet plate 4 from the outside, the plurality of outward expansion guide plates 8 will introduce the airflow into the radiator through the plurality of side air inlets 7, and at the same time, the air inside the radiator cannot actively flow out from the inside of the side air inlet plate 1 to the outside, which plays a one-way guide effect to improve the heat dissipation efficiency of the radiator.

[0021] like Figure 2 and Figure 6 As shown, in this embodiment, the lower end of the rear wind shield 6 is provided with a flange 9, and the flange 9 cooperates with the fixed end of the radiator water tank 2. It can be seen that the radiator water tank 2 and the rear wind shield 6 are installed and connected together. The rear wind shield 6 is designed with a flange 9 at the bottom to improve its structural strength, and at the same time, it can block air, reduce air loss from the installation gap at the rear end of the radiator, and ensure that more air can flow through the radiator water tank 2.

[0022] like Figure 1 and Figure 7 As shown, in this embodiment, the end of the power line of the cooling fan 51 is provided with a waterproof plug 10. It can be seen that the waterproof plug 10 on the end of the power line of the cooling fan 51 has the effect of dustproof and waterproof, ensuring that the vehicle can still dissipate heat normally under poor environmental conditions to improve reliability.

[0023] like Figure 1 and Figure 3 As shown, in this embodiment, a plurality of fixed buffer rubber pads 11 are arranged at the bottom of the fixed bracket 1, and the fixed bracket 1 cooperates with the top mounting position of the vehicle through the plurality of fixed buffer rubber pads 11. It can be seen that the fixed rubber pads 11 are used to absorb the vibration energy generated during operation to prevent the radiator and the top frame of the vehicle body and other structural parts from resonating.

[0024] The working principle of the utility model is as follows: the radiator is installed on the top of the vehicle, and the front air flow component 3 is facing forward. After the vehicle is started, the motor and the internal components generate heat, and the cooling fan 51 is actively turned on. During the operation of the vehicle, the air flow enters the radiator from the front air flow component 3 and the side air inlet plates 4, and the coolant enters the box body 21 through the water inlet 23 through the liquid cooling system in the vehicle. The air flow passes through the several heat sinks 22 in the middle of the box body 21 and the heat enters the air guide cover 52 through the rectangular air inlet 53. The cooling fan 51 blows the heat in the air guide cover 52 out of the vehicle through the circular air outlet 54. After the coolant temperature drops, it continues to circulate in the vehicle through the water outlet 24. When the vehicle is running at low power, the cooling fan 51 is actively turned off to realize automatic vehicle roof-mounted active heat dissipation.

[0025] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
