[0031] like Figures 1 to 4As shown, this utility model provides a heat dissipation system for electric vehicles, including a housing 100, a heat dissipation mechanism, a ventilation mechanism, and a power mechanism; the housing 100 is equipped with a battery 102, a controller 103, and a heat dissipation mechanism, and the heat dissipation mechanism is connected to the battery 102 and the controller 103; the ventilation mechanism is located at the end of the housing 100 and is connected to the heat dissipation mechanism; the output end of the power mechanism is connected to the ventilation mechanism for driving the ventilation mechanism to operate.

[0032] In this embodiment, the heat dissipation system includes a housing 100, a heat dissipation mechanism, a ventilation mechanism, and a power mechanism. The heat dissipation mechanism is connected to the battery 102 and controller 103 inside the housing 100 to cool them down. The heat dissipation mechanism is also connected to the ventilation mechanism to reduce the heat absorbed by the heat dissipation mechanism from the battery 102 and controller 103, thereby minimizing the heat generated inside the housing 100 and dissipating the heat. This controls the temperature of the battery 102 and controller 103, improves the heat dissipation efficiency of the battery 102, and increases the safety and lifespan of the battery 102.

[0033] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the heat dissipation mechanism includes a heat sink 104, which is located inside the housing 100. The heat sink 104 is connected to the battery 102 and the controller 103 respectively, and the end of the heat sink 104 is connected to the ventilation mechanism.

[0034] In this embodiment, the heat dissipation mechanism includes a heat sink 104. Preferably, one end of the heat sink 104 is directly disposed inside the battery 102, and the other end protrudes from the housing 100 where the battery 102 is located and is directly connected to the ventilation mechanism to dissipate heat from the battery 102. The heat sink 104 controls the temperature of the battery 102, thereby ensuring that the battery 102 will not experience thermal runaway, maintaining the battery 102 in its optimal operating state at all times, minimizing the safety hazards caused by thermal runaway, improving user safety and the service life of the battery 102.

[0035] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, one end of the heat sink 104 is located inside the battery 102. The battery 102 also contains several battery cells 105 arranged in parallel. The heat sink 104 is attached to the side wall of each battery cell 105.

[0036] In this embodiment, the battery 102 contains a plurality of battery cells 105 arranged in parallel. Heat sinks 104 are attached to the sidewalls of each battery cell 105. Preferably, the battery cells 105 are arranged in two rows, and the heat sinks 104 are directly installed between the two rows of battery cells 105 and are attached to the sidewalls of both rows of battery cells 105, thereby absorbing heat and dissipating the heat through a ventilation mechanism.

[0037] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the end of the heat sink 104 facing the controller 103 protrudes from the battery 102 and extends to the ventilation mechanism.

[0038] In this embodiment, the heat sink 104 protrudes from the battery 102 at one end facing the controller 103 and extends directly to the ventilation mechanism. It can absorb the heat of the controller 103 while absorbing the heat of the battery 102, and extends in one direction to the ventilation mechanism to facilitate heat dissipation by the ventilation mechanism.

[0039] According to one embodiment provided by this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the controller 103 is located between the battery 102 and the ventilation mechanism, and the outer wall of the controller 103 is in contact with the heat sink 104.

[0040] In this embodiment, the controller 103 is also attached to the side wall of the heat sink 104. The heat sink 104 absorbs the heat of the controller 103 and dissipates the heat. Optionally, the heat sink 104 can be attached to the top or bottom wall of the controller 103 to ensure that it can fully absorb the heat of the controller 103 and dissipate the heat of the controller 103 to the greatest extent possible, so that the temperature of the controller 103 will not affect the temperature of the battery 102.

[0041] The controller 103 is located between the battery 102 and the ventilation mechanism. After the heat sink 104 absorbs the heat generated by the battery 102, it extends to the ventilation mechanism and is attached to the outer wall of the controller 103. At the same time, it absorbs heat and dissipates heat through the ventilation mechanism.

[0042] According to one embodiment provided by this utility model, such as Figure 3 and Figure 4 As shown, the ventilation mechanism also includes a fan 106, which is located at the end of the housing 100 and is connected to the heat sink 104.

The fan 106 can be installed by a mounting bracket to ensure the stability of the fan 106, and the fan 106 can be driven to operate by a power mechanism.

[0044] The heat sink 104 absorbs the heat from the battery cell 105 and the controller 103 and quickly transfers it away until the fan 106 is driven by the power mechanism to dissipate the heat and generate hot air flow, thereby achieving a cooling effect. The fan 106 controls the temperature of the battery 102 and the controller 103 and plays a role in regulating the thermal overload of the entire system. It can effectively improve the working efficiency of the battery 102, prevent thermal runaway, and improve the safety of use.

[0045] When the fan 106 is set as a front fan 106, the controller 103 is located between the battery 102 and the fan 106, and the controller 103 is in contact with the heat sink 104 that protrudes from the battery 102 and extends to the fan 106; when the fan 106 is set as a rear fan 106, the controller 103 and the fan 106 are located opposite each other on both sides of the battery 102, that is, one end of the heat sink 104 protrudes from the battery 102 and extends to the fan 106, and the other end protrudes from the battery 102 and extends to the controller 103, and is in contact with the outer wall of the controller 103 to dissipate heat.

[0046] According to one embodiment of the present invention, the power mechanism includes a power component, which is disposed inside the housing 100 and whose output end is connected to the fan 106 in a transmission manner.

[0047] In this embodiment, the power mechanism includes a power component, which is directly fixed inside the housing 100 and its output end is directly connected to the wind speed. The power component drives the fan 106 to operate, so as to generate hot air flow. The output power of the power component can be adjusted according to actual use needs to change the operating speed of the fan 106, thereby achieving the effect of temperature regulation of the battery 102 and the controller 103.

[0048] According to one embodiment of the present invention, the power component is a drive motor.

[0049] In this embodiment, preferably, the power component is a motor, which is directly fixed to the ground cover plate via a motor mount.

[0050] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2As shown, the housing 100 is provided with a bottom cover 101, and the battery 102, control and drive motor are all fixed to the bottom cover 101.

[0051] In this embodiment, a bottom cover 101 is provided at the bottom of the housing 100. The battery 102, controller 103 and drive motor are directly fixed to the upper surface of the bottom cover 101, which facilitates the direct insertion of the battery 102, controller 103 and drive motor.

[0052] This utility model also provides an electric vehicle, including the above-mentioned cooling system.

[0053] In this embodiment, the electric vehicle using the cooling system can fully control the temperature of the battery 102 and the controller 103, ensure the heat dissipation efficiency of the battery 102 and the controller 103, increase the user's safety, reduce accidents caused by the electric vehicle due to overheating, and improve the overall user experience and driving experience.

[0054] Optionally, the housing 100 of the heat dissipation system can be directly replaced by the body of an electric vehicle. The other principles are the same as those described above for the heat dissipation system, so they will not be repeated here.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
