SPECIFIC EMBODIMENTS
The technical solution provided by the present disclosure will be clearly and completely understood from the following detailed description by reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments.
According to the embodiment of the present disclosure, all other embodiments obtained by those skilled in the art without making creative labor fall within the scope of the present disclosure.
In one embodiment, referring to Figures 1-8, a heat dissipation device for a HUS08575 battery of a new energy vehicle comprises a base 1, the base 1 is placed horizontally to be connected with a vehicle frame, and a cavity can be directly set in the middle of the vehicle frame to fix the base 1 to the bottom of the vehicle, increasing the rigidity of the base 1 and enabling the base 1 to be used as a guard plate at the bottom of the vehicle. A placement box 2 that can be moved up and down is provided above the base 1, the placement box 2 is a rectangular structure with an opening at the top, vent grooves 34 are provided at both the left and right ends of the placement box 2, and an air filter can be installed in the vent grooves 34 in order to avoid dust from affecting the electrical components inside the placement box 2. The bottom of the placement box 2 is provided with left-right oriented relief grooves 33. The heat dissipation device for a battery of a new energy vehicle further comprises a heat dissipation mechanism 3, an air-intake mechanism 4, and a clamping mechanism 23.
The air-intake mechanism 4 comprises a rotating shaft 5 rotationally connected to the upper left side of the placement box 2, the rotating shaft 5 being disposed in a front-back orientation, as depicted in the orientation in the accompanying Figure 2. A partition 7 is provided below the rotating shaft 5, a plurality of relief holes 8 are evenly distributed in the middle of the partition 7, a fan 9 is provided in the middle of the relief holes 8, and the fan 9 can generate airflow from left to right. And the width of the partition 7 is the same as the spacing between the rotating shaft 5 and the bottom of the placement box 2.
That is to say, after the partition 7 is rotated to the up-and-down orientation as shown in the accompanying Figure 2, the partition 7 separates the left side and the right side of the placement box 2. A circular-arc deflector 6 is provided vertically on the left side of the partition 7, and the radius of the circular-arc deflector 6 is the width of the partition 7.
At this time, the air above the circular-arc deflector 6 can enter the left side of 17908575 the partition 7 along the circular-arc deflector 6 and flow towards the interior of the placement box 2 through the push of the fan 9, while the gas entering the breathable groove 34 at the left end of the placement box 2 will flow along the lower side of the circular-arc deflector 6 towards the lower right side, and ultimately pass through the relief grooves 33 to reach the base 1. However, when the partition 7 is rotated to the horizontal orientation, the left and right sides of the placement box 2 are conducted, and the gas entering from the vent grooves 34 on the left side of the placement box 2 can flow directly to the right and be discharged through the vent grooves 34 on the right side of the placement box 2, so that the rotating shaft 5 drives the rotation of the partition 7 to realize the change of direction for airflow.
For the heat dissipation mechanism 3, left- and right-oriented heat-conducting strips 35 are provided on the upper surface of the base 1 against the right side, and the dimensions of the heat-conducting strips 35 are matched with the dimensions of the relief grooves 33, so that the heat-conducting strips 35 move upwardly through the relief grooves 33 when the placement box 2 is moved downwardly. The length of the heat-conducting strips 35 is shorter than that of the relief grooves 33, which allows the gases entering the left vent grooves 34, as they flow downwardly with the circular-arc deflector 6, to pass through the relief grooves 33 to reach the upper part of the base 1. Stand columns 24 are vertically provided at the right end of the base 1 on both the front and back sides, and a front-back oriented fixed frame 25 is provided at the upper end of the column 24, which is in the form of a rectangular-ambulatory-plane knot and in which a plurality of front-back oriented heat dissipation fins 26 are provided in the fixed frame 25. In addition, an S-shaped rotary heat dissipation pipe 27 is arranged inside the fixed frame 25.
The rotary heat dissipation pipe 27 passes through the heat dissipation fins 26, HUS08575 so that the heat from the rotary heat dissipation pipe 27 can be transferred to the heat dissipation fins 26 and the heat from the rotary heat dissipation pipe 27 is taken away by the flow of airflow. A cavity is provided in the interior of the base 1, the cavity being in conduction with the rotary heat dissipation pipe 27.
A heat dissipation medium, such as a coolant, is placed inside the cavity and the rotary heat dissipation tube 27, and the bottom of the heat-conducting strips 35 is extended into the cavity of the base 1, so that the heat of the heat-conducting strips 35 can be conducted into the coolant. A water pump 28 is provided at the right end of the base 1. The water pump 28 is provided in the middle of the rotary heat dissipation pipe 27. The power provided to the water circuit by the water pump 28 allows the coolant in the water circuit to have sufficient pressure to form a circulation, thereby realizing heat exchange.
The clamping mechanism 23 comprises a sliding crossbeam 14 and a fixed crossbeam 16 disposed on the left and right sides of the placement box 2, respectively, and the sliding crossbeam 14 and the fixed crossbeam 16 are provided with mounting holes, which are connected to the threaded holes on the battery, thereby achieving effective fixation of the battery.
In one case of the present embodiment, guiding columns 21 are vertically provided at all four corners of the upper surface of the base 1, with the upper part of the guiding columns 21 slidably connected to the bottom of the placement box 2. A buffer spring 22 is provided between the placement box 2 and the base 1, and the buffer spring 22 is sleeved on the outside of the guiding columns 21 . Thus, when the battery is placed inside the placement box 2, the battery increases the weight of the placement box 2, causing the placement box 2 to move downwardly along the guiding columns 21, allowing the heat-conducting strips 35 to reach inside the placement box 2 to contact the lower surface of the battery, thereby realizing the effect of heat exchange.
Furthermore, since the distance between the placement box 2 and the base 1 17508575 may change, the portion of the rotary heat dissipation pipe between the fixed frame 25 and the base 1 may be deformed. In view of this, bellows can be used, which ensure that the coolant inside the base 1 can still be circulated properly in the water circuit when the placement box 2 is moved up and down.
In one case of the present embodiment, in order to improve the intelligence of the whole device, a temperature sensor as well as a humidity sensor may be provided inside the placement box 2, and a drive motor 10 may be provided outside the front sidewall of the placement box 2. The output shaft of the drive motor 10 is fixedly connected to the first bevel gear 11, the first bevel gear 11 is meshed with the second bevel gear 12, the second bevel gear 12 is fixedly connected to the front end of the rotary shaft 5, and the fan 9 is also provided with a motor inside. When it is raining or the humidity is high, the drive motor can be activated to rotate the partition 7 downward, so that the battery can be separated from the air in the outside environment. When the air intake is low and causes the temperature of the batteries inside the placement box 2 to be high, the partiton 7 can still be rotated downward to achieve heat dissipation of the batteries through the airflow of the fan 9.
In one case of the present embodiment, the left-right oriented sliding grooves 13 are set at the lower left side of the front and rear side walls of the placement box 2, with the middle part of the sliding grooves 13 slidably connected to front-rear oriented sliding beams 14, and the size adjustment assembly 32 is provided on the left side of the sliding grooves 13. The leftmost position of the sliding crossbeam 14 can be adjusted by the size adjustment assembly 32 to realize that the batteries of different sizes can be well fixed. The size adjustment assembly 32 comprises a fixed block 19 provided on the left side of the sliding groove 13 and fixedly connected to the placement box 2.
The middle part of the fixed block 19 is threadedly connected to the left-right HUS08575 oriented clamping screw 18, and the right end of the clamping screw 18 is rotatably connected to the clamping block 20, which is slidably connected to the left side of the sliding grooves 13. Therefore, the left-right position of the clamping block 20 can be adjusted by the clamping screw 18, that is, the left-right sliding position of the sliding crossbeam 14 can be adjusted, so that batteries of different sizes can be well fixed.
In one case of the present embodiment, the fixed crossbeam 16 and sliding crossbeam 14 are provided with stoppers 15. And the stopper 15 is slidable back and forth on the sliding crossbeam 14 or the fixed beam 16 to enable the stopper 15 to avoid the position where the battery needs to be wired, so that the wires of the battery can be placed freely to avoid the wires from being bent and damaged. The rotary holding assembly 17 is disposed on the fixed crossbeam 16. The rotary holding assembly 17 comprises a right-angle splint 30. The right-angle splint 30 is composed of two plates that are perpendicular to each other. The right-angle end of the right-angle splint 30 is rotatably connected to the stopper 15. A pad is provided on the left side of the right-angle splint 30 so that when the right-angle splint 30 is rotated counterclockwise, the pad will fall on the fixed crossbeam 16, thereby allowing the plate on the left side of the right-angle splint 30 to be rotated to a horizontal state for receiving the battery. And a balance weight lever 31 is provided on the right side of the right-angle splint 30, and with the action of the balance weight lever 31, the opening of the right-angle splint 30 can be kept facing up when the battery is not placed, so as to facilitate the placing of the battery. When installing the entire battery, the clamping screw 18 is first rotated to adjust the left and right positions of the clamping block 20 so that the dimensions of the entire clamping mechanism 23 conform to the dimensions of the battery. At this point, the battery is lifted horizontally and the left end of the battery is placed on the sliding crossbeam 14 in a downwardly inclined position, with the left end of the battery resting against the stopper 15 on the sliding beam 14.
At this time, the battery is moved downwardly, and the left end of the battery HUS08575 will push the sliding crossbeam 14 to the left side, with the sliding crossbeam 14 in contact with the clamping block 20 to stop moving. At this time, the right side of the battery is released, the right end of the battery falls downwardly, the right end of the battery will come into contact with the left side of the right-angle splint 30, and the right-angle splint 30 rotates counterclockwise, thereby causing the left padding block 29 of the right-angle splint 30 to come into contact with the fixed crossbeam 16. At this point, the battery is in a horizontal state, and both the left and right ends of the battery are in contact with the sliding crossbeam 14 and the fixed crossbeam 16, so that it is possible to fix the battery with the fixed crossbeam 16 and the sliding crossbeam 14 by means of a bolt connection.
During the implementation of the present embodiment, the entire device must first be installed, and the entire base 1 must be stably installed in the middle of the frame by welding or bolting. Subsequently, the battery is installed, and after the battery is placed in the placement box 2, the weight of the placement box 2 as a whole increases, causing the buffer spring 22 to be compressed, which allows the placement box 2 to move downwardly, the heat-conducting strips 35 move upwardly through the relief grooves 33, and the upper part of the heat-conducting strips 35 supports the bottom part of the battery. At this point, the battery is installed. During installation, it is necessary to place the left end of the placement box 2 facing the front of the vehicle, the right end of the placement box 2 facing the rear part of the vehicle, and the vent grooves 34 on the left side of the placement box 2 to connect with the air inlet on the front side of the vehicle, or an auxiliary connection can be made through an air pipe so that the airflow can enter the vent grooves 34 through the air pipe after the vehicle hits the wind. A cover is set above the placement box 2, and a gap is left above the left side of the placement box 2, so that the gas inside the car can enter the placement box 2 through the left side of the placement box 2. At this time, the overall installation process is completed.
When the vehicle is in motion and the outside environment is in a dry state, the HUS08575 partition 7 is rotated to a horizontal direction, and the outside airflow will directly enter into the placement box 2 through the vent grooves 34. The airflow will carry away a certain amount of heat when it flows through the battery body, and when the airflow flows through the heat dissipation fins 26, the heat of the heat dissipation fins 26 is carried away, thereby causing the cooling medium to cool down. The cooling medium is moved in the vicinity of the heat-conducting strip 35 under the circulating action of the water pump 28 to allow the heat of the battery to be transferred through the heat-conducting strips 35 to the cooling medium to dissipate the heat.
When the vehicle is in parked standby, no outside air enters at this time. The temperature sensor inside the placement box 2 detects that the battery temperature is high, and the drive motor 10 starts to work to make the partition 7 rotate counterclockwise through the gear transmission, with the partition 7 rotating to a vertical state. And the fan 9 starts to work, generating airflow from left to right, so that the gas inside the car can pass through the circular-arc deflector 6 and enter the interior of the placement box 2. This part of the gas will dissipate heat for the battery as in the above-mentioned working process.
When the vehicle is driving in a rainy environment, the outside gas with high humidity will first enter the placement box 2, and the humidity sensor inside the placement box 2 will detect it. The partition 7 can be controlled to rotate to the vertical direction by the driving motor 10 again. The airflow generated by the fan 9 allows the dry gas inside the car to dissipate heat for the battery. At this time, since the vehicle is working, the battery generates a lot of heat, and the airflow generated by the vehicle hitting the wind will enter between the bottom of the placement box 2 and the base 1 along the lower surface of the circular-arc deflector 6.
These air flows with higher humidity will pass through the heat-conducting HUS08575 strips 35, and the airflow with high humidity will directly cool the heat-conducting strips 35, which improves the heat dissipation efficiency of the heat-conducting strips 35 as well as the heat dissipation efficiency of the battery. In the present application there is a gap between adjacent heat-conducting strips 35, so that air can pass through smoothly.
The present invention is applicable to a heat dissipation device for a battery of a new energy vehicle by providing heat-conducting strips 35 to hold up the battery, allowing the bottom of the battery also to have enough space to facilitate air circulation for heat dissipation. Furthermore, the angle of the partition 7 can be adjusted based on the state of the incoming air of the external environment, so that a forced air flow can occur within the vehicle itself through the fan 9, ensuring the cooling efficiency of the battery.
