[0002] New energy vehicles (NEVs) are vehicles that utilize non-traditional internal combustion engines (such as gasoline and diesel) and utilize alternative energy sources such as electricity, hydrogen, and hybrid power. These vehicles primarily include battery electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs), and hydrogen fuel cell vehicles (FCEVs). The batteries in NEVs generate significant heat during charging and discharging. Excessively high temperatures can degrade battery performance and even lead to damage or safety risks. Therefore, NEV cooling tanks are essential to effectively dissipate heat generated by the batteries through circulating coolant.
[0003] During the use of the cooling water tank of traditional new energy vehicles, the coolant is transported to these heat source locations through a water pump to absorb excess heat. Afterwards, the coolant with heat flows into the cooling water tank. The water tank releases the heat to the outside air through auxiliary equipment such as radiators and fans, thereby cooling the coolant.
[0004] In the process of dissipating heat from the coolant, the coolant is only cooled by the fan blowing through the cooling fins. When the ambient temperature is too high in summer or the temperature inside the car is too high, the problem of low heat dissipation efficiency affects the heat dissipation efficiency of the radiator of new energy vehicles.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] Reference Figure 1 and 2The utility model provides an embodiment of a new energy vehicle heat dissipation water tank, comprising a water tank 1, a water return port 2 provided inside the water tank 1 for feeding hot coolant into the water tank 1; a water outlet 3 provided inside the water tank 1 for discharging the cooled liquid out of the water tank 1; a box body 4 fixedly connected to one side of the water tank 1; a symmetrically arranged fan 5 provided inside the box body 4 for increasing air circulation and enhancing heat dissipation effect; a semiconductor refrigeration plate 7 fixedly connected to the inside of the box body 4; a heat conduction plate 8 fixedly connected to one side of the semiconductor refrigeration plate 7; and the heat conduction plates 8 arranged in a linear array and fixedly connected to one side of the semiconductor refrigeration plate 7. The heat conducting plate 8 is arranged inside the water tank 1 to effectively conduct the cooling effect to the inside of the water tank. A heat dissipation component is provided on one side of the semiconductor refrigeration plate 7. The heat dissipation component is used to dissipate the heat generated by the semiconductor refrigeration plate 7. The inside of the box body 4 is provided with heat dissipation ports 6 arranged in a linear array for dissipating heat. The heat dissipation component includes a heat dissipation plate 9 and a heat dissipation column 10. The heat dissipation column 10 is arranged in a rectangular array and fixedly connected to one side of the heat dissipation plate 9. The heat dissipation plate 9 is fixedly connected to the other side of the semiconductor refrigeration plate 7 to ensure that the heat dissipation plate 9 can efficiently transfer the heat of the semiconductor refrigeration plate 7 to the heat dissipation column 10, so that the air flow can carry away the heat.
[0033] Specifically, when the coolant inside the water tank 1 is dissipated, the cooling surface of the semiconductor refrigeration plate 7 quickly generates low temperature and conducts the low temperature to the inside of the water tank 1 through the heat conduction plate 8, so that the temperature of the coolant can be effectively reduced, thereby achieving the purpose of rapid cooling and heat dissipation. At the same time, the heating surface of the semiconductor refrigeration plate 7 begins to generate heat and is in close contact with the heat dissipation plate 9 to ensure efficient heat transfer. The heat dissipation plate 9 further expands the contact area with the outside air through the heat dissipation columns 10 on its surface, thereby enhancing the heat dissipation effect. When the heat absorbed by the heat dissipation column 10 increases, the fan 5 will quickly inhale the outside air and filter the air through the dustproof net 13 to prevent impurities from entering the inside of the box 4. Subsequently, the treated air is blown to the outer wall of the heat dissipation column 10, quickly taking away the heat on its surface, and finally the hot air is discharged out of the box 4 through the heat dissipation port 6, thereby greatly improving the heat dissipation efficiency of the coolant inside the water tank 1 and effectively ensuring the stable operation of the device.
[0034] Reference Figure 3-Figure 5, a fixed frame 11 is fixedly connected to one side of the box body 4, and an L-shaped slide 15 arranged in a ring array is provided inside the fixed frame 11 to guide the sliding of the fixed ring 12. The fixed ring 12 is slidably connected to the inside of the fixed frame 11, and a dustproof net 13 is fixedly connected to the inside of the fixed ring 12 to filter dust in the air. A connecting block 14 is fixedly connected to the outer wall of the fixed ring 12. The connecting block 14 is used to cooperate with the L-shaped slide 15 to ensure the stable positioning of the fixed ring 12. A card slot 17 is provided inside the fixed ring 12 for cooperating with the double-sided wedge-shaped card block 16 to ensure the stable positioning of the fixed ring 12. The fixed frame 11 is fixedly connected to a double-sided wedge-shaped block 16, which is used to limit the fixing ring 12 to prevent it from moving during operation. A sealing ring 18 is fixedly connected to one side of the fixing ring 12. The sealing ring 18 fits inside the fixing frame 11 to ensure the sealing between the dustproof net 13 and the fixing frame 11 to prevent dust from entering the box body 4. The connecting block 14 is slidably connected to the inside of the L-shaped slide 15. The connecting block 14 is engaged with the double-sided wedge-shaped block 16 to ensure that the fixing ring 12 remains stable in the correct position.
[0035] Specifically, when the dust screen 13 needs to be disassembled and cleaned, the operator only needs to put his hand into the slot 17 and gently rotate the fixing ring 12 counterclockwise. As the connecting block 14 on the fixing ring 12 slides smoothly in the L-shaped slot 15, the fixing ring 12 and the fixing frame 11 are gradually separated. The operator can easily pull out the fixing ring 12, thereby completing the separation from the fixing frame 11, and conveniently take out the dust screen 13 for cleaning. When the cleaning is completed and it needs to be reinstalled, it is only necessary to reinsert the connecting block 14 of the fixing ring 12. The fixing ring 12 is then rotated clockwise in the L-shaped slot 15 so that the inclined surface of the connecting block 14 is securely embedded in one side of the double-sided wedge-shaped block 16. At this time, the fixing ring 12 is firmly locked on the fixing frame 11 to ensure the stability of the device. The fixing ring 12 and the fixing frame 11 are tightly sealed by the sealing ring 18, which effectively prevents dust from entering the interior of the box body 4 through the connection gap. This design not only realizes dust-proof protection for the interior of the box body 4, but also greatly simplifies the disassembly and cleaning process of the dustproof net 13, greatly improving the convenience of maintenance.
[0036] Working principle: When using the new energy vehicle cooling water tank, first, when the coolant inside the water tank 1 is cooled, the cooling surface of the semiconductor refrigeration plate 7 generates low temperature and conducts it to the inside of the water tank 1 through the heat conduction plate 8, so that the low temperature cools down the coolant and dissipates heat. The heating surface of the semiconductor refrigeration plate 7 generates heat and contacts the heat sink 9 for heat dissipation. At the same time, the heat on the heat sink 9 increases the contact area with the air through the heat dissipation column 10. When the heat on the heat dissipation column 10 is cooled, the fan 5 filters the external air through the dustproof net 13 and then sucks it into the box body 4 and blows it to the outer wall of the heat dissipation column 10 for heat dissipation. Finally, it is discharged from the heat dissipation port 6, thereby improving the heat dissipation effect of the coolant inside the water tank 1. The dustproof net 13 needs to be disassembled and cleaned afterwards. When cleaning, just put your hand into the card slot 17, then rotate the fixing ring 12 counterclockwise, the connecting block 14 on the fixing ring 12 slides in the L-shaped slide groove 15, and then pull out the fixing ring 12 to separate the fixing ring 12 from the fixing frame 11, and clean the dustproof net 13. When installing, the fixing ring 12 is inserted into the L-shaped slide groove 15 through the connecting block 14 and then rotated clockwise so that the connecting block 14 is inserted into one side of the double-sided wedge-shaped block 16 through the inclined surface of the double-sided wedge-shaped block 16, and then the fixing ring 12 is locked to it. The fixing ring 12 and the fixing frame 11 are sealed by the sealing ring 18 to prevent dust from entering the interior of the box body 4 from the gap between them, thereby achieving the effect of dustproofing the interior of the box body 4 and facilitating the removal of the dustproof net 13.
[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
