Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of mobile charging vehicles, in particular to a heat dissipation device for mobile charging vehicles. Background Art

[0002] Existing mobile charging vehicles often move outdoors when working. In the hot summer, the sun shines directly on the roof of the charging vehicle. The top of the charging vehicle is in direct contact with the outside world, and the heat exchange efficiency with the interior of the vehicle is high. At the same time, the equipment inside the vehicle itself is also heating up, causing the cooling system of the charging vehicle itself to overload and easily cause damage to components. Utility Model Content

[0003] The purpose of the utility model is to solve the above-mentioned problem and provide a heat dissipation device for a mobile charging vehicle.

[0004] The technical solution of the utility model is achieved in this way:

[0005] The utility model provides a heat dissipation device for a mobile charging vehicle, comprising a vehicle body, and the heat dissipation device comprises:

[0006] An air induction slot is arranged in a concave manner on the top of the vehicle body;

[0007] An air inlet slot is provided on the slot wall around the air inlet slot, and the air inlet slot is connected to the vehicle body;

[0008] An air outlet is provided on the side wall of the vehicle body, is communicated with the air inlet slot, and is provided with a fan;

[0009] A top plate is installed on the top of the vehicle body, with a fixed interval between the top plate and the top of the vehicle body to form an air inlet space, and a convex plate is provided below the top plate, and an outer edge surface of the convex plate also has an inclined surface, which reduces the interval between the top and the upper edge surface of the air duct.

[0010] The advantages or beneficial effects of the above technical solution include at least:

[0011] The isolation space formed by the top plate and the top of the vehicle body prevents the top of the vehicle body from directly exchanging heat with the outside world, but isolates it, and the convex plate forms a Venturi effect at the notch of the air duct, allowing air to enter the isolation space, and the heat of the isolation space is taken away by the air, and the cooperation of the air inlet slot, the fan and the air outlet forms an air circulation path from the outside to the inside of the vehicle body and then from the inside to the outside, thereby taking away the heat generated by the operation of the equipment inside the vehicle body.

[0022] Reference Figure 1 and Figure 2 A heat dissipation device for a mobile charging vehicle includes a vehicle body 10, and the heat dissipation device includes:

[0023] The air inlet groove 21 is arranged in a concave manner at the top of the vehicle body 10; the air inlet groove 22 is opened on the groove wall around the air inlet groove 21, and the air inlet groove 22 is connected with the vehicle body 10; the air outlet 23 is opened on the side wall of the vehicle body 10, is connected with the air inlet groove 22, and is provided with a fan 26. The fan 26 can suck the outside air into the vehicle body 10 through the air inlet groove 22, and then discharge the air from the air outlet 23 of the vehicle body 10, so that convection from the inside of the vehicle body 10 to the outside is formed, flowing from the upper part to the lower part of the vehicle body 10, realizing air circulation and achieving the purpose of heat dissipation.

[0024] Furthermore,

[0025] The heat dissipation device includes a top plate 24, which is installed on the top of the vehicle body 10. There is a fixed interval between the top plate 24 and the top of the vehicle body 10 to form an air inlet space 25. The air inlet space 25 can isolate the roof of the vehicle body 10 from the outside world to prevent the roof from being exposed to direct sunlight, thereby further improving the heat dissipation efficiency. In addition, there is a convex plate 241 below the top plate 24. The outer edge of the convex plate 241 also has an inclined surface to reduce the resistance of the edge of the convex plate 241 to the air. Figure 2 As shown in the dotted circle in the upper part, when the outside air passes through the air inlet space 25 to reach the bottom of the convex plate 241, the flowing air enters the narrow channel, and the air encounters a greater resistance than the outside world, which increases the flow speed of the air and causes the air to be quickly brought into the induced draft space, which is similar to the Venturi effect. The Venturi effect, also known as the Venturi effect, describes the phenomenon that the speed of a fluid (whether liquid or gas) increases while the pressure decreases when passing through a narrow channel.

[0026] As a further improvement of the above structure, the groove walls around the air inlet groove 21 are inclined, and the inclination angle is an acute angle, so that the notch of the air inlet groove 22 can be enlarged, further increasing the air intake volume. However, in order to prevent large objects from entering the air inlet groove 21 and falling into the air inlet groove 22, there are a plurality of air inlet grooves 22, and each of the air inlet grooves 22 is also spaced at a fixed interval. A plurality of air inlet grooves 22 are arranged in an array along the edge of the air inlet groove 21, such as Figure 2 As shown, larger debris can be prevented from falling into the air inlet slot 22 to the greatest extent.

[0027] Based on the above structure, the part of the vehicle body 10 below the air duct 21 also has an insulating chamber 11 to isolate the equipment in the vehicle body 10 from the top of the vehicle body 10. Since part of the sunlight will still pass through the bottom of the top plate 24 to the bottom of the air duct 21, the insulating chamber 11 can be isolated to reduce the heat exchange between the bottom of the air duct 21 with a higher temperature and the interior of the vehicle body 10 as much as possible, thereby improving the heat dissipation efficiency. In another embodiment, the outer edge of the top plate 24 extends beyond the side edge of the vehicle body 10, which can avoid sunlight from passing through the bottom of the top plate 24 to the bottom of the air duct 21 to the greatest extent, and can also prevent rainwater from dripping into the air duct 21 when it rains.

[0028] Furthermore, the top plate 24 is connected to the vehicle body 10 via a column 242 so that a fixed interval is maintained between the top plate 24 and the top of the vehicle body 10. One end of the column 242 is fixedly connected to the vehicle body 10, and the other end is detachably connected to the top plate 24, so that the user can remove the top plate 24 and clean the air duct 21.

[0029] refer to Figure 3 As a further improvement of the above structure, a dust baffle 12 is provided at the position of the air outlet 23 of the vehicle body 10. The dust baffle 12 is arranged to be tilted downward, which can prevent debris from entering the vehicle body 10 from the air outlet 23 to the greatest extent.

[0030] Furthermore, a filter is installed inside the vehicle body 10 around the equipment inside the vehicle body 10. Except for the panel for the internal equipment of the vehicle body 10 to interact with the outside world, a gap is left between the rest of the filter and the inner wall of the vehicle body 10. The air entering from the air inlet slot 22 will circulate in the gap. At the same time, the gap can also prevent the debris entering from the air inlet slot 22 from affecting the equipment inside the vehicle body 10 to the greatest extent, thereby ensuring safety.

They are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.

[0032] Those skilled in the art should understand that the above embodiments are only for the purpose of clearly illustrating the present invention, and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications may be made based on the above disclosure, and these changes or modifications are still within the scope of the present invention.
