Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted power supplies, in particular to a positioning heat dissipation structure for a vehicle-mounted external power supply. Background Art

[0002] The on-board external power supply is a key component for automobile energy replenishment. It can enhance the user's endurance when outdoors. In addition, as an external power supply, it can also be used for other purposes, greatly facilitating the user's outdoor travel.

[0003] However, there are some problems in actual use. Since the battery will dissipate heat during the discharge stage, or when the temperature is high in summer, the battery will be too hot. This requires the use of some heat dissipation structures to keep the battery temperature at an appropriate state. The devices used for battery heat dissipation in the prior art are usually air-cooled or water-cooled devices. When the battery temperature or ambient temperature is too high, the heat dissipation capacity of the air-cooled device is insufficient; the water-cooled device usually places the battery in a confined space, exchanges heat with the air in the confined space through an evaporator, and the condenser dissipates the collected heat to the outside, and circulates the coolant through a water pump. However, the air flow is poor. When the battery temperature is too high, its refrigeration capacity is limited. Increasing the refrigeration power will cause a large consumption of electrical energy.

[0004] Therefore, we propose a positioning heat dissipation structure for a vehicle-mounted external power supply to solve the above-mentioned problems.

[0005] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field.

[0030] See also Figure 1-Figure 5 A positioning heat dissipation structure for an on-board external power supply includes: a roof box, an air cooling component, a liquid cooling component, and a mode adjustment component. The mode adjustment component can select a separate air cooling mode, a water cooling mode, or a heat dissipation mode combining air cooling and water cooling according to the actual use of the battery and the influencing factors such as the ambient temperature. When heat dissipation is required but the battery temperature is not too high, a more energy-saving method can be selected, which is more economical and can also enhance its endurance.

[0031] The roof box comprises a roof box chassis 1 and a roof box cover 2 arranged on the top of the roof box chassis 1, the roof box chassis 1 is provided with a first vent 3 and a second vent 4, the roof box chassis 1 is provided with three chambers, and the second vent 4 is arranged on the side where the middle chamber is located;

[0032] The air cooling assembly includes a first motor 7 and a fan 16 rotatably connected to the first motor 7. The fan 16 is disposed at the first vent 3. The first motor 7 is disposed in one of the side chambers of the roof box chassis 1. When the air cooling mode is used alone, the liquid cooling assembly does not work. The first motor 7 drives the fan 16 to rotate, inhales external air, and discharges it through the second vent 4.

[0033] The liquid cooling assembly is arranged in the middle chamber of the roof box chassis 1, and the liquid cooling assembly includes a liquid cooling machine 15, a first heat exchange fin 11 and a second heat exchange fin 12. The liquid cooling machine 15 is connected with the first heat exchange fin 11 and the second heat exchange fin 12 through a liquid inlet pipe 13. The liquid cooling assembly also includes a mounting plate 14, and the mounting plate 14 is arranged in the middle chamber of the roof box chassis 1. The liquid cooling machine 15 is fixed to the upper surface of the mounting plate 14, and the first heat exchange fin 11 and the second heat exchange fin 12 are arranged below the mounting plate 14. The liquid cooling assembly also includes a heat exchange plate 5, and the heat exchange plate 5 is fixed to the bottom surface of the first heat exchange fin 11 and the second heat exchange fin 12. The heat exchange plate 5 is provided with a positioning and Ventilation hole 6, the diameter of the battery installed on the roof box cover 2 is smaller than the diameter of the positioning and vent hole 6, and the battery is inserted into the positioning and vent hole 6 when used in a one-to-one matching manner. When the battery dissipates heat, it can be cooled by the heat exchange plate 5, the first heat exchange fin 11 and the second heat exchange fin 12. The top of the second heat exchange fin 12 is fixed to the mounting plate 14, and the bottom surfaces of the second heat exchange fin 12 and the first heat exchange fin 11 are parallel. When the liquid cooling mode is used alone, the first vent 3 and the second vent 4 are in a closed state, and the liquid cooler 15 is used for cooling and the coolant therein is passed into the first heat exchange fin 11 and the second heat exchange fin 12, and the heat is taken away by circulation;

[0034] The mode adjustment component includes a second motor 8 and a rotating plate 10, the rotating plate 10 is rotatably connected to the second vent 4, the second motor 8 is fixed in the side chamber of the roof box chassis 1, the output shaft of the second motor 8 is connected to the rotating shaft of the rotating plate 10 through a belt 9, the end of the rotating shaft of the rotating plate 10 passes through another chamber of the roof box chassis 1, and is meshed with a sliding plate 18 through a gear 17. When the air cooling mode is used alone, the first vent 3 and the second vent 4 are both in an open state, so that the internal and external air can exchange heat and take away the heat dissipated by the battery; When using the liquid cooling mode, the first vent 3 and the second vent 4 are both in a closed state; when using a combination of air cooling and liquid cooling, the first motor 7 needs to drive the fan 16 to rotate in the opposite direction to discharge air outward, and the first vent 3 and the second vent 4 need to be in an open state. External air enters through the second vent 4, and the air temperature decreases after passing through the first heat exchange fins 11 and the second heat exchange fins 12. After passing through the positioning and vent holes 6, the air is quickly discharged from the top of the battery through the bottom, and then to the first vent 3. Compared with the other two modes, the heat dissipation is faster and more effective.

[0035] Working principle of this embodiment: the battery is sleeved in the positioning and vent holes 6 on the heat exchange plate 5, and a gap is left between the positioning and vent holes 6 and the battery for air to pass through. When the air cooling mode is used alone, the second motor 8 drives the rotating plate 10 and the sliding plate 18 to move, so that the first vent 3 and the second vent 4 are both in an open state, and the first motor 7 drives the fan 16 to work, let in external air, and the hot air is discharged through the second vent 4; when the liquid cooling mode is used alone, the second motor 8 drives the rotating plate 10 and the sliding plate 18 to move, so that the first vent 3 and the second vent 4 are both in a closed state, and the liquid cooler 15 is started for cooling; when the combination of the two is used, the first motor 7 and the liquid cooler 15 are controlled to work at the same time and discharge air to the outside, and the external air enters through the second vent 4, passes through the positioning and vent holes 6, and is discharged through the first vent 3.
