The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] In related technologies, as the functions and complexity of robots continue to increase, the demand for heat dissipation also increases. Although traditional heat dissipation methods, such as forced air cooling or liquid cooling, can achieve heat dissipation, these heat dissipation methods require a large space occupation, which is not conducive to the miniaturization of robots. Therefore, how to achieve the heat dissipation of robots without increasing the size of the robots has become a major challenge in the field of robot research.

[0043] Reference below Figure 1-Figure 5 A heat dissipation device according to an embodiment of the present invention is described.

[0044] The heat dissipation device 1 according to the present invention includes a main body 11, a shell 12 and a heat dissipation component 13, wherein a control component is arranged in the main body 11; the shell 12 is arranged on at least a part of the periphery of the main body 11, and the shell 12 and the main body 11 are spaced apart to form an air path, and the air path passes through the control component, and an air inlet 151 and an air outlet 152 connected to the air path are formed on the shell 12; the heat dissipation component 13 is arranged in the air path and is suitable for driving the airflow to flow from the air inlet 151 to the air outlet 152.

[0045] According to the heat dissipation device 1 of the present invention, a main body 11 is provided, and the main body 11 is the core structure of the heat dissipation device 1. A series of electrical components such as the control components of the heat dissipation device 1 are arranged in the main body 11. A shell 12 is arranged on the periphery of the main body 11 to protect the main body 11. A gap is reserved between the shell 12 and the main body 11 to avoid interference of the shell 12 with the control components on the main body 11. In actual assembly design, at least part of the gap between the shell 12 and the main body 11 can be used as an air path for heat dissipation of the heat dissipation device 1. Specifically, an air inlet 151 and an air outlet 152 connected to the air path are formed on the shell 12. External air can enter the air path through the air inlet 151 and flow along the air path to the air outlet 152 before flowing out of the heat dissipation device 1. When the airflow flows in the air path, it can take away the heat generated by the control components or other types of electrical components inside the heat dissipation device 1, thereby achieving heat dissipation of the heat dissipation device 1. A heat dissipation component 13 may also be provided in the air path. The heat dissipation component 13 may drive the airflow to flow in the air path, thereby improving the efficiency of the airflow in removing heat, and further improving the heat dissipation efficiency of the heat dissipation device 1 .

[0046] By spacing the main body 11 and the shell 12 to form an air path and ensuring that the path passes through key heating components such as the control components, direct heat extraction is achieved, which can reduce the accumulation of heat inside the heat sink 1, thereby effectively reducing the operating temperature of the internal components and avoiding performance degradation or damage caused by overheating. Compared with the heat dissipation scheme of the related art, the heat sink 1 of the present invention rationally utilizes the gap between the shell 12 and the main body 11, and can define the air path without adding an additional shell structure, and further improves the heat dissipation efficiency through the heat dissipation component. While achieving heat dissipation, the volume of the heat sink 1 is not increased, ensuring the compactness and flexibility of the structure of the heat sink 1, and facilitating the overall design and application of the heat sink 1 and the robot equipped with the heat sink 1.

[0047] According to one embodiment of the present invention, the wind path is arranged around at least part of the outer periphery of the main body 11. The wind path surrounds at least part of the outer periphery of the main body 11 to increase the path of the wind path, that is, to increase the contact area between the airflow and the main body 11 when the airflow flows in the wind path, so that the airflow has more time to interact with the heat, thereby improving the heat dissipation efficiency of the heat dissipation device 1.

[0048] According to one embodiment of the present invention, the outer shell 12 includes: a front shell 121 and a top shell 122, the front shell 121 is arranged at the front of the main body 11, and the front shell 121 is spaced apart from at least a portion of the main body 11 to define an air inlet channel 141 connected to the air inlet port 151; the top shell 122 is arranged at the top of the main body 11 and is connected to the front shell 121, and the top shell 122 is spaced apart from at least a portion of the main body 11 to form a top air duct 142 connected to the air inlet channel 141 and the air outlet 152, respectively.

[0049] The front shell 121 is located at the front of the main body 11 and connected to the main body 11, and the top shell 122 is located at the top of the main body 11 and connected to the front shell 121, ensuring the stability of the structure of the heat dissipation device 1. An air inlet channel 141 is formed between the front shell 121 and the main body 11, and the air inlet channel 141 is connected to the air inlet 151, and the outside air can enter the air inlet channel 141 through the air inlet 151; a top air duct 142 is formed between the top shell 122 and the main body 11, and the top air duct 142 is connected to the air inlet channel 141 and the air outlet 152 respectively, and the airflow in the air inlet channel 141 can flow out from the air outlet 152 after passing through the top air duct 142. It can be simply understood that the air inlet channel 141 and the top air duct 142 jointly define the air path. The design of the top air duct 142 not only increases the surface area of ​​the air path, but also promotes the uniform distribution of the airflow. When the airflow enters from the air inlet channel 141 and passes through the top air duct 142 , it can more fully exchange heat with the heating element inside the main body 11 , thereby improving the heat dissipation efficiency.

[0050] According to one embodiment of the present invention, the top shell 122 includes: a top plate 1221, a first side plate 1222 and a second side plate 1223, the top plate 1221 is spaced apart from the top of the main body 11; the first side plate 1222 is connected to one end of the top plate 1221, the first side plate 1222 extends along the top air duct 142 and is tilted in a direction away from the main body 11; the second side plate 1223 is connected to the other end of the top plate 1221, the second side plate 1223 extends along the top air duct 142 and is tilted in a direction close to the main body 11; wherein the top plate 1221, the first side plate 1222, the second side plate 1223 and the top of the main body 11 together define the top air duct 142.

[0051] like Figure 1-Figure 3As shown, the top shell 122 is provided with a top plate 1221 and a first side plate 1222 and a second side plate 1223. The top plate 1221 is located at the top of the main body 11, and the first side plate 1222 and the second side plate 1223 are respectively connected to the two ends of the top plate 1221, and the first side plate 1222 and the second side plate 1223 gradually move away from each other in the direction from the top plate 1221 toward the main body 11, and the top plate 1221, the first side plate 1222, the second side plate 1223 and the main body 11 jointly define a top air duct 142. The first side plate 1222 is tilted in a direction away from the main body 11, and the second side plate 1223 is tilted in a direction close to the main body 11, so that the first side plate 1222 can guide the airflow of the air inlet channel 141 into the top air duct 142; and the second side plate 1223 can guide the airflow of the top air duct 142 to flow to the air outlet 152. After entering the top air duct 142, the airflow will be guided by the first side plate 1222 and the second side plate 1223 and flow in a predetermined direction, thereby improving the heat dissipation efficiency. The design of the top air duct 142 not only increases the heat dissipation area, but also optimizes the distribution of the airflow through the inclination angle of the side plates. The inclined side plates can guide the airflow to cover the heating element on the top of the main body 11 more evenly, ensuring that the heat can be quickly taken away. In addition, the design of the top air duct 142 also helps to reduce the eddy current and turbulence of the airflow in the air duct, reduce energy loss, and further improve the heat dissipation effect.

[0052] According to one embodiment of the present invention, the heat dissipation assembly 13 includes: a relay fan 131, which is arranged in the air path and is suitable for driving the airflow to flow from the air inlet 151 to the air outlet 152. After the airflow enters the air path from the air inlet 151, it can flow along the air path, but the flow rate of the airflow will be restricted by the air duct. For example, the corner area in the air path will cause certain obstructions to the airflow and reduce the flow rate of the airflow. At this time, the relay fan 131 is arranged in the air path, and the airflow driven by the relay fan 131 can change the flow direction of the airflow, increase the flow rate of the airflow, intensify the heat exchange between the airflow and the main body 11, and improve the heat dissipation efficiency of the heat dissipation device.

[0053] According to one embodiment of the present invention, the housing 12 includes: a front housing 121 and a top housing 122, wherein the front housing 121 is disposed at the front of the main body 11, and the front housing 121 is spaced apart from at least a portion of the main body 11 to define an air inlet channel 141 communicating with the air inlet port 151; the top housing 122 is disposed at the top of the main body 11 and connected to the front housing 121, and the top housing 122 is spaced apart from at least a portion of the main body 11 to form a top air duct 142 communicating with the air inlet channel 141 and the air outlet port 152, respectively; wherein the relay fan 131 is disposed at the connection between the air inlet channel 141 and the top air duct 142, and the relay fan 131 is adapted to drive the airflow of the air inlet channel 141 into the top air duct 142. The relay fan 131 is disposed at the connection between the air inlet channel 141 and the top air duct 142, and its function is to drive the airflow in the air inlet channel 141 to enter the top air duct 142 more effectively. By driving the airflow through the relay fan 131, the flow rate of the airflow can be significantly increased, the heat exchange between the airflow and the main body 11 can be intensified, and it can be ensured that the heat can be quickly taken away from the heat source such as the control component. The relay fan 131 not only enhances the driving force of the airflow, but also optimizes the distribution of the airflow in the air path through the selection of its position. Since the fan is set at the connection between the air inlet channel 141 and the top air duct 142, the relay fan 131 can effectively guide the airflow entering the air inlet channel 141 to the top air duct 142, ensuring that the airflow distribution in the top air duct 142 is more uniform, thereby improving the efficiency of the entire heat dissipation system.

[0054] According to one embodiment of the present invention, the relay fan 131 is constructed as a centrifugal fan, and an air guide inlet connected to the air inlet channel 141 is formed at one axial end of the relay fan 131, and an air guide outlet connected to the top air duct 142 is formed at one radial side of the relay fan 131. The design of the centrifugal fan enables it to accelerate and discharge the airflow entering the air guide inlet in the radial direction, so that the relay fan 131 can effectively guide the airflow in the air inlet channel 141 to the top air duct 142. The rotation of the relay fan 131 enables the airflow to obtain a greater speed and pressure when passing through the relay fan 131. After obtaining sufficient kinetic energy, the airflow can smoothly enter the top air duct 142 along the air guide outlet, thereby ensuring the continuity and efficiency of the airflow. Therefore, the airflow can quickly diffuse into the entire top air duct 142, further improving the heat dissipation effect.

[0055] According to one embodiment of the present invention, a windward wall 150 extending along the air inlet channel 141 and tilted away from the main body 11 is formed at the bottom of the front shell 121, and an air inlet 151 is formed on the windward wall 150. The air inlet 151 is arranged on the windward wall 150, and the windward wall 150 is tilted, so that the heat dissipation device 1 can more easily capture the cold air in front during movement or operation. After entering the heat dissipation device 1, the cold air can more effectively take away the heat generated by the heat source such as the control component, thereby reducing the overall temperature of the heat dissipation device 1 and improving the heat dissipation effect.

[0056] According to an embodiment of the present invention, the heat dissipation assembly 13 further includes: an air inlet fan 132 and / or an air outlet fan 133; the air inlet fan 132 is used to suck the airflow outside the air inlet 151 into the housing 12; the air outlet fan 133 is used to drive the airflow in the air outlet 152 out of the housing 12. In order to improve the heat dissipation efficiency, the heat dissipation assembly 13 can also be provided with an air inlet fan 132 and an air outlet fan 133, wherein the air inlet fan 132 can suck the airflow outside the air inlet 151 into the housing 12, improve the efficiency of the airflow entering the air path, increase the air intake, and enable more airflow to perform heat exchange with the main body 11 in the air path; the air outlet fan 133 drives the airflow in the air outlet 152 out of the housing 12, which can be understood as the airflow after heat exchange in the air path can be discharged from the housing 12 under the action of the air outlet fan 133, and the setting of the air outlet fan 133 can improve the efficiency of the airflow out of the air path, so that the heat dissipation device can timely discharge the airflow after heat exchange, further improving the heat dissipation effect. When assembling the air inlet fan 132 and the air outlet fan 133 , one of the fans can be selected for assembly or both fans can be assembled at the same time according to the heat dissipation requirements.

[0057] According to an embodiment of the present invention, the air inlet fan 132 can be arranged on the windward wall 150, at which time, the inlet of the air inlet fan 132 is connected to the air inlet 151, and the outlet of the air inlet fan 132 is connected to the air inlet channel 141; the air outlet fan 133 can be arranged on the second side plate 1223, at which time, the inlet of the air outlet fan 133 is connected to the top air duct 142, and the outlet of the air outlet fan 133 is directly opposite to the air outlet 152. The air inlet fan 132 and the air outlet fan 133 enable the heat dissipation component 13 to have a stronger active heat dissipation capability. Specifically, the air inlet fan 132 can actively draw the external cold air into the air inlet channel 141, accelerate the air flow, and improve the heat dissipation efficiency; and the air outlet fan 133 can quickly discharge the hot air heated by the heat dissipation system from the outside of the heat dissipation device 1 to avoid the accumulation of heat inside the heat dissipation device 1. The coordinated use of the air inlet fan 132 and the air outlet fan 133 forms a complete air circulation system. Cold air enters the air inlet channel 141 through the air inlet fan 132, and after passing through the heat source such as the control component, the hot air is guided to the top air duct 142, and then discharged by the air outlet fan 133. This orderly airflow circulation can ensure the efficient operation of the heat dissipation system, reduce the heat retention time inside the heat dissipation device 1, and improve the heat dissipation effect of the heat dissipation device 1. During actual assembly, only the air inlet fan 132, or only the air outlet fan 133, or both the air inlet fan 132 and the air outlet fan 133 can be installed according to the heat dissipation requirements.

[0058] In some embodiments, the air intake fan 132 may be installed on the outside of the windward wall 150 or on the inside of the windward wall 150 .

[0059] According to one embodiment of the present invention, the main body 11 includes: a hardware component 111 and an auxiliary heat sink 112, the hardware component 111 is accommodated in the outer shell 12 and is spaced apart from at least part of the outer shell 12 to form an air inlet channel 141; the auxiliary heat sink 112 is arranged on the top surface of the hardware component 111, and the auxiliary heat sink 112 is provided with a heat dissipation outlet, which is open toward the top air duct 142.

[0060] The hardware component 111 is the main heat source of the heat dissipation device 1. An air inlet channel 141 is formed between the hardware component 111 and the front shell 121. When the external airflow enters the air inlet channel 141, it can exchange heat with the hardware component 111.

The hardware component 111 is provided with a heat dissipation outlet open to the top air duct 142, so that the heat generated by the hardware component 111 or other electrical components can quickly enter the top air duct 142 through the auxiliary heat sink 112, and can be easily carried away by the airflow in the top air duct 142. Placing the auxiliary heat sink 112 on the top of the hardware component 111 and opening its heat dissipation outlet toward the top air duct 142 can maximize the use of the natural rising principle of hot air, promote the rapid transfer and dissipation of heat, significantly improve the heat dissipation efficiency, reduce the working temperature of the hardware component 111, and extend the service life of the heat dissipation device 1.

The synergistic effect of the first auxiliary heat dissipation component 1121 and the second auxiliary heat dissipation component 1122 enables the heat inside the heat dissipation device 1 to be dissipated faster. The first auxiliary heat dissipation component 1121 directly guides part of the hot air to the air outlet 152 through the internal air duct, reducing the retention time of the hot air inside the heat dissipation device 1. The second auxiliary heat dissipation component 1122 quickly transfers the heat on the top of the hardware component 111 to the top air duct 142 through its heat dissipation outlet, further accelerating the heat dissipation.

Figure 5As shown, during assembly, the spoiler fan 134 can be arranged in the cavity formed by the rear shell 123 and the main body 11. Since part of the airflow flowing in the top air duct 142 will flow into the cavity formed by the rear shell 123 and the main body 11 and easily stay in this cavity, it will affect the airflow discharge from the housing 12 and the heat dissipation effect. At this time, the spoiler fan 134 is arranged in the cavity formed by the rear shell 123 and the main body 11 to drive the airflow to flow. The flow rate of the gas between the rear shell 123 and the main body 11 is increased through the spoiler effect of the spoiler fan 134, which is convenient for the gas to carry heat to the air outlet fan 133, and the heat dissipation efficiency of the main body 11 is further improved.

At the same time, the temperature of the airflow when flowing into this cavity may be lower than the temperature of the main body, and the outlet of the spoiler fan 134 facing the main body 11 can also enable this part of the airflow to exchange heat with the main body 11 again before being discharged from the outer shell 12, thereby improving the heat dissipation effect of the heat dissipation device 1.

At the same time, the temperature of the airflow when it flows into this cavity may be lower than the temperature of the main body.

The setting of the turbulent fan 134 can prevent the airflow from being retained in the cavity between the shell 12 and the main body 11. At the same time, the temperature of the airflow when it flows into this cavity may be lower than the temperature of the main body. The outlet of the turbulent fan 134 is oriented toward the main body 11, which can also allow this part of the airflow to exchange heat with the main body 11 again before being discharged from the shell 12, thereby improving the heat dissipation effect of the heat dissipation device 1.
