However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0054] In order to thoroughly understand the utility model, a detailed description will be provided in the following description. It should be understood that these embodiments are provided to make the disclosure of the utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. Obviously, the implementation of the embodiments of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the utility model are described in detail below, but in addition to these detailed descriptions, the utility model may also have other embodiments.

[0055] Ordinal numbers such as "first" and "second" cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term "first component" itself does not imply the existence of the "second component", and the term "second component" itself does not imply the existence of the "first component".

[0056] It should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and similar expressions used in the present invention are for illustrative purposes only and are not restrictive.

[0057] The utility model discloses a heat dissipation channel and an AGV robot.

[0058] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

[0059] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in a preferred embodiment, a heat dissipation channel 6 is used to cool down a heat source 4, and includes: a bottom plate 61 and a side plate 62;

[0060] The middle portion of the bottom plate 61 is configured to be an arc convex toward the heat source 4;

[0061] The side plates 62 are arranged on both sides of the bottom plate 61 . The side plates 62 and the bottom plate 61 are combined into a groove-shaped structure to form an airflow channel. The cross-sectional area of ​​the middle part of the airflow channel is smaller than the cross-sectional areas of the two ends.

[0062] Two side panels 62 are arranged on both sides of the bottom plate 61. The two side panels 62 clamp the bottom plate 61 to form an air flow channel. The top of the air flow channel can be open to facilitate the insertion of the heat source 4, or the top plate can be partially closed and an entrance is reserved for the heat source 4.

[0063] The cross section of the airflow channel can be regarded as a rectangle. Since the middle part of the bottom plate 61 is designed to be arc-shaped, the cross-sectional area of ​​the middle part of the airflow channel is reduced and is smaller than the cross-sectional area at both ends, similar to a Venturi tube. By utilizing the Bernoulli effect, the gas flow velocity in the airflow channel can be increased.

[0064] The heat dissipation channel 6 in this embodiment, by designing the air flow channel into a shape that is conducive to gas flow, utilizes the Bernoulli effect to increase the gas circulation speed, thereby facilitating the heat dissipation and cooling of the heat source of the AGV robot. Compared with the prior art, the heat dissipation structure is simplified, the weight of the AGV robot is reduced, and the manufacturing cost is low, and the robot is reliable and durable.

[0065] In one embodiment, if Figure 2 , Figure 3 , Figure 4As shown, one side edge of the side panel 62 is fixedly connected to one side edge of the bottom panel 61, so that the two side panels 62 and the bottom panel 61 are combined to form a groove-shaped structure, the interior of the groove-shaped structure constitutes an air flow channel, and the flow direction of the air flow channel is set along the driving direction of the AGV robot.

[0066] The two side panels 62 are symmetrically arranged on both sides of the bottom panel 61. The side panels 62 and the bottom panel 61 can be vertically connected so that the cross-sectional area of ​​the airflow channel is rectangular; they can also be tilted as needed so that the cross-sectional area of ​​the airflow channel can be trapezoidal.

[0067] The flow direction of the airflow channel is set along the driving direction of the AGV robot, which is beneficial for the airflow to enter and exit the airflow channel when the AGV robot is driving.

[0068] In one embodiment, if Figure 2 , Figure 4 As shown, the slot-shaped structure includes an air inlet 64 and an air outlet 65, which are located at both ends of the air flow channel; when the AGV robot is traveling, the air flow automatically enters from the air inlet 64, passes through the air flow channel, and is discharged from the air outlet 65. The air inlet 64 is always close to the guide plate 5. If the guide plates 5 are set at both ends of the slot-shaped structure, the functions of the air inlet 64 and the air outlet 65 can be interchanged. The positions of the air inlet and the air outlet should be determined according to the driving direction of the AGV robot. The air inlet is facing the front of the AGV robot, and the air outlet is facing the rear of the AGV robot.

[0069] In one embodiment, if Figure 2 , Figure 4 As shown, the groove-shaped structure further includes a notch, which is arranged opposite to the bottom plate 61 , and the notch is closer to the heat source 4 than the bottom plate 61 .

[0070] The slot can be considered as being set at the top of the heat dissipation channel 6, and the heat source 4 extends into the interior of the heat dissipation channel 6 from the slot. The slot is a completely open mouth, which is convenient for the heat source 4 to be inserted. The positional relationship between the heat source 4 and the heat dissipation channel 6 does not require to be very precise, and it is also convenient to install the heat dissipation channel 6 on the bottom of the AGV robot.

[0071] In one embodiment, if Figure 4 As shown, the bottom plate 61 includes:

[0072] A first drainage portion 611, which is in the shape of a flat plate and is disposed at one end of the groove-shaped structure;

[0073] A second drainage portion 612, which is arc-shaped and protrudes toward the heat source 4, and is disposed in the middle of the groove-shaped structure;

[0074] A third drainage portion 613, which is in the shape of a flat plate and is disposed at the other end of the groove-shaped structure;

[0075] The first drainage portion 611 is connected to a first end of the second drainage portion 612 , and the third drainage portion 613 is connected to a second end of the second drainage portion 612 .

[0076] The first guide portion 611 and the third guide portion 613 are provided to more conveniently guide the airflow into and out of the airflow channel.

[0077] In one embodiment, if Figure 4 As shown, the first guide portion 611, the second guide portion 612 and the third guide portion 613 are made in one piece and are naturally connected and transitioned. Natural connection and transition means that there are no obvious protrusions or depressions at the connection position between the first guide portion 611 and the second guide portion 612, and at the connection position between the third guide portion 613 and the second guide portion 612, and a smooth transition state is presented to avoid obstruction to the airflow.

[0078] In one embodiment, if Figure 4 As shown, the heat dissipation channel 6 also includes:

[0079] The connecting ear 63 is fixedly connected to the side plate 62 . The connecting ear 63 is provided with a connecting hole for fixing the heat dissipation channel 6 to the AGV robot. The heat dissipation channel 6 can be fixed to the AGV robot by screws.

[0080] In one embodiment, the side plate 62 and the bottom plate 61 are made in one piece or in separate pieces and are fixedly connected by welding;

[0081] The connecting ear 63 and the side plate 62 are made in one piece or in separate pieces and fixedly connected by welding.

[0082] The side plate 62 and the bottom plate 61 are integrally formed, and the connecting ear 63 and the side plate 62 are integrally formed, and both can be manufactured using sheet metal processing by stamping equipment or bending equipment, and have many advantages such as high manufacturing efficiency, accurate size, and smooth product surface.

[0083] like Figure 1 , Figure 3 As shown, an embodiment of the utility model further provides an AGV robot, comprising: a heat dissipation channel 6 according to any one of the above embodiments.

[0084] Because the heat source 4 is usually disposed at the bottom of the body of the AGV robot, the heat dissipation channel 6 is also disposed at the bottom of the body of the AGV robot, so as to dissipate heat and cool the heat source 4 of the AGV robot.

[0085] When the AGV robot receives the task instruction, it starts running to the designated location. The wind force generated during this period is directed into the heat dissipation channel 6. Due to its special structure, the airflow in the heat dissipation channel 6 is compressed, and the wind speed is increased. The heat generated by the heat source 4 is dissipated from the other end of the heat dissipation channel 6 through the wind force, thereby achieving the heat dissipation effect.

[0086] In one embodiment, the AGV robot further includes:

[0087] The vehicle body 1 is arranged on a vehicle frame 7. Two driving wheels 3 are arranged below the vehicle frame 7 for driving the AGV robot to travel. Four universal wheels 2 are also arranged below the vehicle frame 7 to provide a balancing support for the vehicle frame 7.

[0088] The heat dissipation channel 6 can be fixedly connected to the frame 7. After installation and fixation, the heat dissipation channel 6 is located between the two driving wheels 3, and the lowest point of the heat dissipation channel 6 cannot be lower than the lowest surface of the universal wheel 2 and the driving wheel 3 of the AGV robot to prevent interference with the ground.

[0089] The AGV robot can travel forward or backward, which is very convenient for transporting goods. The principle of turning of the AGV robot with two driving wheels 3 is: when the rotation speeds of the two driving wheels 3 are different, turning can be achieved.

[0090] In one embodiment, the AGV robot further includes:

[0091] The heat source 4 and the heat dissipation channel 6 are arranged below the heat source 4 , and the heat source 4 extends into the heat dissipation channel 6 .

[0092] The heat source 4 can be any one or more of the power supply, control module, motor, etc. of the AGV robot, and is the main heat-generating component when the AGV robot is running.

[0093] Due to its special structure, the heat dissipation channel 6 compresses the airflow in the heat dissipation channel 6, increases the wind speed, and dissipates the heat generated by the heat source 4 from the other end of the heat dissipation channel 6 through wind force, thereby achieving a heat dissipation and cooling effect.

[0094] In one embodiment, if Figure 2 , Figure 3 As shown, the AGV robot also includes:

[0095] The guide plate 5 is arranged at one end or both ends of the heat dissipation channel 6 , and the guide plate 5 at one end is used to guide the airflow into the heat dissipation channel 6 each time.

[0096] The main function of the guide plate 5 is to ensure and guide as much wind force generated by the movement of the AGV robot as possible to the inside of the heat dissipation channel 6. Considering that the AGV robot can travel in different directions, guide plates 5 are provided at both ends of the heat dissipation channel 6. Figure 5 The figure shows the wind direction when the AGV robot is running, and the same is applicable when the AGV robot is running in the reverse direction, that is, when the AGV robot can run in both directions, the guide plates 5 can be installed at both ends of the heat dissipation channel 6.

[0097] In one embodiment, if Figure 2 As shown, the guide plate 5 includes:

[0098] Flat plate portion 51;

[0099] An arc portion 52, the arc portion 52 is connected to the top of the heat dissipation channel 6;

[0100] The flat plate portion 51 is disposed at the front end of the arc-shaped portion 52 . The flat plate portion 51 and the arc-shaped portion 52 are used to guide airflow into the heat dissipation channel 6 .

[0101] The flat plate portion 51 and the arc portion 52 are naturally connected and transitioned. The natural connection and transition means that there is no obvious protrusion or depression at the connection position between the flat plate portion 51 and the arc portion 52, and a smooth transition is presented to avoid obstruction to the airflow.

[0102] The flat plate portion 51 and the arc portion 52 are integrally formed or separately formed and fixedly connected by welding. The flat plate portion 51 and the arc portion 52 are integrally formed and can be manufactured by stamping equipment or bending equipment using sheet metal technology, which has many advantages such as high manufacturing efficiency, accurate size, and smooth product surface.

[0103] In one embodiment, the flat portion 51 and the arc portion 52 are both provided with connection holes, and are connected and fixed to the frame 7 of the AGV robot by screws.

[0104] In one embodiment, if Figure 6 , Figure 7 As shown, the minimum distance between the bottom of the heat source 4 and the bottom of the heat dissipation channel 6 is less than 8 mm. From the simulation data, the heat dissipation channel 6 has a better cooling effect on the heat source 4 at this time.

[0105] Table 1. Figure 6 Heat dissipation simulation data of the heat dissipation channel 6 with the channel cross-sectional shape 2 shown in FIG.

[0106] <![CDATA[Inlet flow velocity v0 (m / s)]]> 0 1 2 3 Average wall temperature of heat source (℃) 48.0 38.5 36.0 34.6 Average wall temperature drop rate / 20％ 25％ 28％

[0107] In one embodiment, the heat dissipation channel 6 and the guide plate 5 are both made of stainless steel plates. Stainless steel has the characteristics of corrosion resistance and rust resistance. Even if the AGV robot works in a humid, salt spray or other environment, the heat dissipation channel 6 and the guide plate 5 have an extremely long service life.

[0108] In one embodiment, an exhaust fan may also be provided at the end of the heat dissipation channel 6, for example, at the air outlet of the heat dissipation channel 6. When the AGV robot is started, the exhaust fan is started synchronously, which can promote the air flow in the heat dissipation channel 6 and discharge the heat of the heat source 4. If the AGV robot is in a parking state, the airflow generated by the AGV robot cannot be relied on to dissipate the heat of the heat source 4, and the exhaust fan can be started to dissipate the heat of the heat source 4.

[0109] like Figure 6 , Figure 7 As shown, after simulation, we can draw the following conclusions:

[0110] This heat dissipation channel 6 structure has a more obvious effect on the heat dissipation of the AGV robot. Figure 6 As shown in simulation result 1, when the vehicle speed is 1m / s, the average wall temperature of the heat source can be reduced by about 20%;

[0111] like Figure 7 As shown in simulation result 2, the cross-sectional shape of the heat dissipation channel and the running speed of the AGV robot can affect the average wall temperature of the heat source. That is, the three factors of the running speed of the AGV robot, the heat dissipation effect and the cross-sectional shape of the channel need to be fitted through multiple sets of simulations to achieve the design parameters that are most suitable for the working conditions.

[0112] Table 2. Figure 7 Heat dissipation simulation data of heat dissipation channel 6 with channel cross-sectional shape 1 shown in FIG.

[0114] The utility model provides a heat dissipation channel and an AGV robot, which has the following characteristics:

[0115] 1. Simple structure and strong applicability. Compared with the prior art, the utility model can be applied in more working conditions. In the prior art, the use of condensate requires a fan and a large temperature difference, which has great limitations in applicability. The heat pipe for circulating condensate is formed by a stamping process, which has poor reliability.

[0116] 2. Save the internal space of the AGV robot. The utility model mainly dissipates the heat of the heat source outside the vehicle through the wind generated by the AGV robot. When in use, the heat dissipation channel needs to be connected to the bottom of the vehicle body without occupying the internal space of the vehicle body, thereby solving the problem of narrow internal space of the light-load AGV robot.

[0117] 3. It can reduce the sound pressure value in the logistics workshop. When the AGV robot is in normal operation, the utility model uses the generated wind power to dissipate heat. There is no noise generated by fans, motors, etc., which reduces the sound pressure value in the logistics workshop and improves the comfort of employees.

[0118] 4. Cost saving: the utility model uses fewer parts, which can reduce the cost of the parts themselves; it is easy to assemble, which can reduce the assembly cost; it has fewer components and higher reliability, which can effectively reduce parts loss.
