Description

Technical Field

[0001] This invention relates to a heat dissipation device, and more particularly to a combined heat dissipation device for temperature control management of new energy vehicle batteries. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source and integrate advanced technologies such as vehicle power control and drive. They are characterized by advanced technical principles, new technologies, and new structures. New energy vehicles include four types: hybrid electric vehicles, pure electric vehicles, fuel cell electric vehicles, and other new energy vehicles.

[0003] Currently, all new energy vehicles that use electricity to ensure normal operation on the road are equipped with batteries. During the driving process, the batteries of new energy vehicles will continuously generate heat. Therefore, it is necessary to dissipate heat from the batteries, otherwise it will affect the use and lifespan of the new energy vehicle. Existing new energy vehicle batteries are generally cooled by water. First, after the coolant continuously absorbs the heat from the new energy vehicle battery, the temperature of the coolant will also gradually rise, resulting in poor subsequent heat dissipation. Moreover, this heat dissipation method is difficult to control the heat dissipation area, making it difficult to effectively dissipate heat from areas with high temperatures, resulting in poor heat dissipation effect. Summary of the Invention

[0004] In order to overcome the shortcomings of existing methods for cooling new energy vehicle batteries, which have poor heat dissipation effects, the purpose of this invention is to provide a combined heat dissipation device for new energy vehicle battery temperature control management that can improve heat dissipation effect.

[0005] The technical solution is: a combined heat dissipation device for temperature control management of new energy vehicle batteries, including a placement plate, heat pipes and liquid cooling module. The heat pipes are connected to the placement plate and are connected to the liquid cooling module. Multiple batteries are installed at intervals inside the placement plate. It also includes an air guide frame, a baffle, an air cooling mechanism and an adjustment mechanism. The air guide frame is connected to the placement plate, and the baffles are rotatably connected to both the front and rear sides of the air guide frame. The air cooling mechanism is used to dissipate heat from the batteries, and the adjustment mechanism is used to regulate the heat dissipation area.

[0006] Furthermore, the air-cooling mechanism includes a refrigeration module, a negative pressure fan, a rotating plate, an air inlet frame, a baffle, and elastic elements. The refrigeration module is connected to the air guide frame, and multiple negative pressure fans are connected at intervals inside the air guide frame. The negative pressure fans are located below the refrigeration module. Two rotating plates are rotatably connected to the air guide frame. Air inlet frames are connected to both the front and rear sides of the air guide frame. Baffles are slidably connected to each air inlet frame, and elastic elements are connected between each baffle and the adjacent air inlet frame.

[0007] Furthermore, the adjustment mechanism includes a drive assembly, a fixed base, a transmission roller, a cam, a pulley assembly, and a baffle plate. Fixed bases are symmetrically connected to the front and rear of the air guide frame. Transmission rollers are rotatably connected to each fixed base. A baffle plate is rotatably connected inside the air guide frame. The baffle plate and the adjacent transmission roller are driven by the pulley assembly. The drive assembly is used to drive the transmission roller and the baffle plate to rotate. A cam is connected to the opposite end of each transmission roller. When the cam rotates, it contacts the baffle plate.

[0008] Furthermore, the drive assembly includes a dual-axis servo motor, a cross clamp, and an electric push rod. The dual-axis servo motor is slidably connected to the air guide frame. Cross clamps are connected to the output shafts on both the front and rear sides of the dual-axis servo motor. The electric push rod is connected to the air guide frame. The dual-axis servo motor is connected to the telescopic rod of the electric push rod.

[0009] Furthermore, it also includes a lifting mechanism for driving the rotating plate to rotate upward and open. The lifting mechanism includes a limit component, a sliding member, and a pull rope. The sliding member is slidably connected to the air guide frame and contacts the rotating plate. The pull rope is connected to the sliding member and slides through the air guide frame. The limit component is used to limit the rotation plate.

[0010] Furthermore, the limiting component includes a first locking block, a rotating first locking block on the air guide frame, and the first locking block blocks the top of the rotating plate.

[0011] Furthermore, it also includes a positioning mechanism for limiting the transmission roller. The positioning mechanism includes a second locking block, a spring, and a pusher. The second locking block is slidably connected to the fixed base. The second locking block locks the transmission roller. A spring is connected between the second locking block and the fixed base. Two pushers are connected to the dual-axis servo motor.

[0012] Furthermore, it also includes a protective mechanism for protecting the air guide frame. The protective mechanism includes a mounting frame and a dustproof net. The mounting frame is connected to the left side of the refrigeration module, and the dustproof net is connected to the mounting frame.

[0013] Furthermore, it also includes a locking mechanism for limiting the blocking frame. The locking mechanism includes a sliding frame and a rotating block. The sliding frame is slidably connected to the placement plate and blocks the outside of the blocking frame. The rotating block is rotatably connected to the air guide frame and blocks the sliding frame.

[0014] Furthermore, the lower part of the air guide frame is made of a heat-conducting material.

[0015] The beneficial effects are:

[0016] 1. The air intake frame of the present invention can utilize the driving power of the car to quickly guide the air next to the car into the air guide frame to dissipate heat from the battery. At the same time, the liquid cooling module can control the circulation of coolant in the heat pipe to dissipate heat from the battery. Through the combined heat dissipation method, a better heat dissipation effect is achieved.

[0017] 2. This invention controls the forward and backward movement of a dual-axis servo motor to drive the corresponding baffle to rotate and open. Then, through the cooperation of the cooling module and the negative pressure fan, cold air is blown into the air guide frame to dissipate heat from the battery, thereby achieving the purpose of regulating the heat dissipation area and more effectively dissipating heat from the battery with a high temperature, thus improving the heat dissipation efficiency.

[0018] 3. The second locking block of the present invention can lock the transmission roller and prevent the transmission roller from rotating randomly, thereby ensuring that the cross locking component and the transmission roller are accurately engaged. Attached Figure Description

Detailed Implementation

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0032] A combined heat dissipation device for battery temperature control management in new energy vehicles, such as Figures 1-6 As shown, it includes a placement plate 1, a heat pipe 2, and a liquid cooling module 3. The heat pipe 2 is connected to the placement plate 1 and is connected to the liquid cooling module 3. Multiple batteries 4 are installed at intervals inside the placement plate 1. It also includes an air guide frame 5, a baffle 6, an air cooling mechanism 7, and an adjustment mechanism 8. The air guide frame 5 is welded to the placement plate 1. The lower part of the air guide frame 5 is made of heat-conducting material. The baffle 6 is rotatably connected to both the front and rear sides of the air guide frame 5. The air cooling mechanism 7 is used to dissipate heat from the batteries 4 by air cooling. The adjustment mechanism 8 is used to adjust the heat dissipation area.

[0033] like Figure 1 and Figure 3 As shown, the air-cooling mechanism 7 includes a cooling module 71, a negative pressure fan 72, a rotating plate 73, an air inlet frame 74, a baffle 75, and an elastic element 76. The cooling module 71 is connected to the air guide frame 5. Multiple negative pressure fans 72 are bolted at intervals inside the air guide frame 5. The negative pressure fans 72 are located below the cooling module 71. The cooling module 71 and the negative pressure fans 72 work together to blow cold air into the air guide frame 5 to dissipate heat from the battery 4. Two rotating plates 73 are rotatably connected to the air guide frame 5. Air inlet frames 74 are connected to both the front and rear sides of the air guide frame 5. Baffles 75 are slidably connected to each air inlet frame 74. Elastic elements 76 are connected between each baffle 75 and the adjacent air inlet frame.

[0034] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the adjusting mechanism 8 includes a drive assembly, a fixed base 83, a transmission roller 84, a cam 88, a pulley assembly 85, and a baffle plate 86. Fixed bases 83 are symmetrically welded to the front and rear of the air guide frame 5. Each fixed base 83 is rotatably connected to a transmission roller 84. A cam 88 is connected to the far end of each transmission roller 84. When the cam 88 rotates, it contacts the baffle plate 75. A baffle plate 86 is rotatably connected inside the air guide frame 5. The baffle plate 86 and the adjacent transmission roller 84 are connected via the pulley assembly 85. The drive assembly is used to drive the transmission roller 84 and the baffle plate 86 to rotate. When the baffle plate 86 rotates to a vertical position, it can block the cold air and adjust the heat dissipation area. The drive assembly includes a dual-axis servo motor 81, a cross clamp 82 and an electric push rod 87. The dual-axis servo motor 81 is slidably connected to the air guide frame 5. The cross clamp 82 is connected to the output shafts on both the front and rear sides of the dual-axis servo motor 81. The electric push rod 87 is bolted to the air guide frame 5. The dual-axis servo motor 81 is connected to the telescopic rod of the electric push rod 87.

[0035] First, rotate the blocking frame 6 upwards to open it. Then, install the battery 4 on the placement plate 1. Next, rotate the blocking frame 6 downwards to close it. The blocking frame 6 can protect the battery 4. Then, install this device on the new energy vehicle. When the new energy vehicle is driving, the battery 4 will dissipate heat. At this time, the air next to the vehicle will quickly enter the air guide frame 5 through the air intake frame 74, thereby dissipating heat from the battery 4. At the same time, the liquid cooling module 3 can control the coolant to circulate in the heat conduction pipe 2, thereby absorbing the heat dissipated by the battery 4 and achieving the purpose of dissipating heat from the battery 4. The heat dissipation effect is good. When the temperature of the front battery 4 is too high, the electric push rod 87 can control the dual-axis servo motor 81 to move forward, driving the cross clamp 82 to move forward, so that the front cross clamp 82 engages with the front transmission roller 84, and then it can be opened. The dual-axis servo motor 81 drives the cross-shaped clamp 82 to rotate. The front cross-shaped clamp 82 drives the front transmission roller 84 to rotate. Through the pulley assembly 85, the front baffle 86 can be rotated 90 degrees to open. At the same time, the front transmission roller 84 drives the front cam 88 to rotate, causing the front cam 88 to squeeze the front baffle 75 downward. The front elastic element 76 is compressed, causing the front baffle 75 to block the front air inlet frame 74. Then, the negative pressure fan 72 blows air into the air guide frame 5. The cooling module 71 can cool the air entering the air guide frame 5, so that there is a continuous flow of cold air in the air guide frame 5, which can better dissipate heat from the front battery 4 and improve the heat dissipation effect. Similarly, when the rear baffle 86 rotates 90 degrees to open, it can also better dissipate heat from the rear battery 4.

[0036] like Figure 1 , Figure 7 and Figure 8As shown, it also includes a lifting mechanism 9, which includes a limiting component, a sliding member 92, and a pull rope 93. The sliding member 92 is slidably connected to the air guide frame 5 and contacts the rotating plate 73. The pull rope 93 is connected to the sliding member 92 and slides through the air guide frame 5. The limiting component is used to limit the rotating plate 73. The limiting component includes a first locking block 91. The first locking block 91 is rotatably mounted on the air guide frame 5 and blocks the top of the rotating plate 73. Initially, the first locking block 91 blocks the top of the rotating plate 73. When people need to clean the inside of the air guide frame 5, the first locking block 91 can be rotated 90 degrees so that the first locking block 91 no longer blocks the top of the rotating plate 73. Then, the lower part of the pull rope 93 can be pulled to the right so that the upper part of the pull rope 93 can drive the sliding member 92 to move to the left. The sliding member 92 will squeeze the rotating plate 73 to rotate upward and open, making it convenient for people to clean the inside of the air guide frame 5.

[0037] like Figure 1 and Figure 9 As shown, it also includes a positioning mechanism 10, which includes a second locking block 101, a spring 102, and a pusher 103. The second locking block 101 is slidably connected to the fixed base 83, and the second locking block 101 locks the transmission roller 84, thereby preventing the transmission roller 84 from rotating arbitrarily. A spring 102 connects the second locking block 101 to the fixed base 83. Two pushers 103 are welded to the dual-axis servo motor 81. Initially, the second locking block 101 locks the transmission roller 84, preventing it from rotating arbitrarily, thus ensuring precise engagement between the cross-shaped locking member 82 and the transmission roller 84. When the dual-axis servo motor 81... When the dual-axis servo motor 81 moves backward, it drives the pusher 103 to move backward. When the pusher 103 on the rear side contacts the second locking block 101 on the rear side, it squeezes the second locking block 101 on the rear side to move backward. The spring 102 on the rear side is compressed, causing the second locking block 101 on the rear side to release the transmission roller 84 on the rear side. Then, the cross locking member 82 on the rear side can precisely engage with the transmission roller 84 on the rear side, thereby driving the wind deflector 86 on the rear side to rotate 90 degrees to a vertical state. Similarly, when the dual-axis servo motor 81 moves forward, it can drive the second locking block 101 on the front side to move forward and release the transmission roller 84 on the front side.

[0038] like Figure 1 and Figure 10 As shown, it also includes a protective mechanism 11, which includes a mounting frame 111 and a dustproof net 112. The mounting frame 111 is bolted to the left side of the cooling module 71, and the dustproof net 112 is connected to the mounting frame 111. The dustproof net 112 can filter the air entering the air guide frame 5 and prevent a large amount of dust from entering the air guide frame 5.

[0039] like Figure 1 and Figure 11As shown, it also includes a locking mechanism, which includes a sliding frame 121 and a rotating block 122. The sliding frame 121 is slidably connected to the placement plate 1, and the sliding frame 121 blocks the outside of the blocking frame 6. The rotating block 122 is rotatably connected to the air guide frame 5, and the rotating block 122 blocks the sliding frame 121. When the blocking frame 6 is rotated downward to close, the sliding frame 121 can be slid to the right to block the outside of the blocking frame 6. Then the rotating block 122 is rotated downward to press against the sliding frame 121, thereby locking the blocking frame 6 through the sliding frame 121 and preventing the blocking frame 6 from rotating upward to open, thus preventing the battery 4 from sliding out.

[0040] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
