Abstract

This utility model relates to a heat exchange structure for an industrial robot chassis, comprising a long, narrow space within the chassis, air inlets staggered along the height direction with outer and inner side plates respectively, and a heat exchange mechanism sealed within the long, narrow space and spaced apart from the two air inlets. Each air inlet is connected to a fan for supplying air into the long, narrow space. Air outlets are provided on both the outer and inner side plates, staggered along the height direction.

Description

Technical Field

[0001] This utility model relates to the field of heat exchange, and more particularly to the field of chassis technology, specifically a heat exchange structure for an industrial robot chassis. Background Technology

[0002] Industrial robots are automated, reprogrammable, and multi-purpose manipulators designed for industrial applications. They possess multi-jointed manipulators or multi-degree-of-freedom structures and can perform processing tasks through power and control systems. Their core components include the robot body, drive system, and control system.

[0003] Industrial robots consist of robotic arms and control cabinets. When the components inside the control cabinet operate, they generate heat, which requires heat dissipation. However, traditional heat dissipation involves directly introducing outside air and cooling it through internal circulation. But outside air is dusty and cannot be used in harsh environments or for control cabinets that require strict conditions for circulating air. Furthermore, the space inside the control cabinet is limited. Therefore, there is an urgent need for a heat exchange structure for industrial robot chassis. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a heat exchange structure for industrial robot chassis. By setting up heat exchange plates to separate the outside environment from the chassis cavity, the air inside the chassis cavity and the outside air exchange heat through the heat exchange plates, thereby achieving heat exchange while preventing outside air from entering the chassis cavity.

[0005] This utility model is achieved through the following technical solution: a heat exchange structure for an industrial robot chassis, including a narrow space located inside the chassis, air inlets arranged alternately in the height direction and respectively provided on an outer side plate and an inner side plate, and a heat exchange mechanism sealed in the narrow space and spaced apart from two air inlets, with a fan connected to each of the two air inlets to deliver air into the narrow space, and air outlets provided on both the outer side plate and the inner side plate, with the two air outlets arranged alternately in the height direction.

[0006] In use, this invention separates the outside world from the inner cavity of the chassis by setting up a heat exchange plate. Air inside the chassis is blown onto the heat exchange plate by a fan, and after exchanging heat with the heat exchange plate, the air outlet on the inner side plate returns to the chassis. Outside air is sent into the narrow space by another fan, absorbs heat from the heat exchange plate, and is discharged from the air outlet on the outer side plate. Thus, heat exchange is achieved while preventing outside air from entering the chassis, meeting practical needs.

[0007] Preferably, the fan connected to the outside is located in a narrow space, and the fan connected to the inner cavity of the chassis is located inside the inner cavity of the chassis.

[0008] This preferred solution places the fan connected to the outside inside the casing, which facilitates the transportation of the casing and also protects the fan. Since the space is limited in the narrow space, another fan is placed inside the casing cavity.

[0009] Preferably, the heat exchange mechanism includes a heat exchange plate and a support frame connecting the heat exchange plate and the narrow space, wherein the support frame and the heat exchange plate are sealed within the narrow space.

[0010] This preferred solution uses a support frame to support the heat exchange plate.

[0011] Preferably, the air outlet on the inner side plate is located above the air outlet on the outer side plate, the air inlet on the inner side plate is located above the air outlet on the inner side plate, the air outlet on the outer side plate and the air inlet on the inner side plate are directly opposite each other, and the heat exchange plate is located above the air inlet on the outer side plate.

[0012] In this preferred embodiment, the air inlet and outlet positions on the outer and inner side panels are arranged to achieve airflow between the two sides of the heat exchange plate within the narrow space.

[0013] Preferably, the heat exchange plate and the support frame are slidably and sealed together in the narrow space along the air inlet direction. The support frame includes an upper support plate connected to the upper end of the heat exchange plate and a lower support plate connected to the lower end of the heat exchange plate. The lower support plate is an inclined plate that is inclined from the outside to the inside and from top to bottom. A sliding block is fixedly connected to the bottom end of the lower support plate and is slidably and sealed together on the inner side plate along the sliding direction of the heat exchange plate.

[0014] In use, this preferred solution adjusts the width of the heat exchange space on both sides of the heat exchange plate by adjusting the position of the support frame and the heat exchange plate. Since the outdoor temperature is different in summer and winter, the fan power needs to be increased in summer to dissipate heat quickly, while the outdoor temperature is low in winter and the heat exchange is relatively sufficient. Therefore, under the condition of stable fan output power, in summer, the cold air volume is small, causing the heat exchange plate to move outward, reducing the outer heat exchange space and increasing the inner heat exchange space. As a result, the air velocity in the outer heat exchange space increases, and the fast-flowing air quickly carries away the heat from the heat exchange plate. The air velocity in the inner heat exchange space is small, so that the inner air and the heat exchange plate can fully exchange heat, thereby improving the heat exchange efficiency.

[0015] Conversely, in winter, the large amount of cold air from the outside causes the heat exchange plates to move inward, reducing the heat exchange space on the inside and increasing the heat exchange space on the outside. As a result, the air velocity in the inner heat exchange space increases, thus achieving rapid heat exchange, while the air velocity in the outer heat exchange space is small, allowing the outer air to fully exchange heat with the heat exchange plates, thereby improving heat exchange efficiency.

[0016] Preferably, the heat exchange plate has a center fixedly connected to a limiting post extending to the outside, the limiting post has limiting holes arranged along the sliding direction of the heat exchange plate, the outer side plate has a limiting pin inserted into the limiting hole, and the outer side plate also has a limiting seat that cooperates with the limiting pin.

[0017] This preferred solution uses a limiting post to adjust the position of the heat exchange plate, and then uses a limiting pin to fit into the limiting hole and a limiting seat to position the heat exchange plate.

[0018] Preferably, the heat exchange plate has a heat exchange cavity, an elongated air inlet hole communicating with the heat exchange cavity is formed on the bottom surface of the heat exchange plate, and an elongated air outlet hole communicating with the heat exchange cavity is formed on the outer side surface of the heat exchange plate. In this preferred embodiment, air enters the heat exchange cavity during use, thereby achieving rapid heat exchange.

[0019] Preferably, the heat exchange cavity is further provided with several heat exchange columns connecting the outer and inner sides of the heat exchange cavity.

[0020] This preferred solution enhances the strength of the heat exchange plate and improves the heat exchange effect on both the inner and outer surfaces of the heat exchange plate by setting up heat exchange columns.

[0021] The beneficial effects of this invention are as follows: By setting up the heat exchange plate, the outside world and the inner cavity of the chassis are separated. Air inside the chassis cavity is blown onto the heat exchange plate by a fan, and after exchanging heat with the heat exchange plate, the air outlet on the inner side plate returns to the chassis. Outside air is sent into the narrow space by another fan, absorbs heat from the heat exchange plate, and is discharged from the air outlet on the outer side plate. Thus, while achieving heat exchange, it prevents outside air from entering the chassis, meeting practical needs. By adjusting the position of the support frame and the heat exchange plate, the width of the heat exchange space on both sides of the heat exchange plate can be adjusted. Because outdoor temperatures differ between summer and winter, increased fan power is needed in summer for rapid heat dissipation. In winter, the outside temperature is low, resulting in relatively sufficient heat exchange. Therefore, with a stable fan output power, the smaller amount of cold air outside in summer causes the heat exchange plates to move outward, reducing the outer heat exchange space and increasing the inner heat exchange space. Consequently, the air velocity in the outer heat exchange space increases, and the rapidly flowing air quickly carries away the heat from the heat exchange plates. The air velocity in the inner heat exchange space is low, allowing for more thorough heat exchange between the inner air and the heat exchange plates, thus improving heat exchange efficiency.

[0022] Conversely, in winter, the large amount of cold air from the outside causes the heat exchange plates to move inward, reducing the heat exchange space on the inside and increasing the heat exchange space on the outside. As a result, the air velocity in the inner heat exchange space increases, thus achieving rapid heat exchange, while the air velocity in the outer heat exchange space is small, allowing the outer air to fully exchange heat with the heat exchange plates, thereby improving heat exchange efficiency.

[0029] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0030] Example 1:

[0031] See attached document Figure 1 This utility model discloses a heat exchange structure for an industrial robot chassis, including a narrow space 1 located inside the chassis. The narrow space 1 is a hexahedron with all six sides being rectangular. The height of the hexahedron is greater than its width. Two plates arranged along the width direction of the narrow space 1 are an inner plate and an outer plate. The inner plate is located between the outer plate and the inner cavity of the chassis.

[0032] Both the outer and inner side panels are provided with air inlets and air outlets. The two air inlets are staggered in the height direction, and the two air outlets are staggered in the height direction. A heat exchange mechanism is also provided in the narrow space 1, which is sealed in the narrow space 1 and spaced apart from the two air inlets.

[0033] The air outlet 5 on the inner side plate is located above the air outlet on the outer side plate, and the air inlet 4 on the inner side plate is located above the air outlet on the inner side plate. The air outlet on the outer side plate and the air inlet on the inner side plate are directly opposite each other, and the heat exchange plate 6 is located above the air inlet on the outer side plate.

[0034] The fan connected to the outside is located in the narrow space 1, and the fan connected to the inner cavity of the chassis is located inside the inner cavity of the chassis.

[0035] A heat exchange mechanism with two air inlets spaced apart is also sealed within the elongated space 1. The heat exchange mechanism includes a heat exchange plate 6 and a support frame connecting the heat exchange plate 6 and the elongated space 1. The support frame and the heat exchange plate 6 are sealed within the elongated space 1. The support frame includes an upper support plate connected to the upper end of the heat exchange plate 6 and a lower support plate 8 connected to the lower end of the heat exchange plate 6. The lower support plate 8 is an inclined plate that slopes downwards from the outside to the inside. The bottom end of the lower support plate 8 is fixed to an inner side plate, and the upper support plate is fixed to the top plate of the elongated space 1. A sealing ring is provided on the circumferential surface of the heat exchange plate 6, sealingly connecting with the side wall of the elongated space 1. Sealing strips are also provided between the upper support plate and the lower support plate 8 and the corresponding side wall of the elongated space 1. This achieves a sealed arrangement of the two air inlets between the heat exchange mechanism.

[0036] Specifically, attached Figure 1 The horizontal direction represents the width of the narrow space, and the vertical direction represents the height of the narrow space.

[0037] In this embodiment, the heat exchange plate 6 separates the outside world from the inner cavity of the chassis. Air inside the chassis is blown onto the heat exchange plate 6 by a fan, and after exchanging heat with the heat exchange plate 6, the air outlet of the inner side plate returns to the chassis. Outside air is sent into the narrow space 1 by another fan, absorbs the heat from the heat exchange plate 6, and is discharged from the air outlet of the outer side plate. Thus, heat exchange is achieved while preventing outside air from entering the chassis, meeting practical needs.

[0038] Example 2:

[0039] See attached document Figure 2-4 This utility model discloses a heat exchange structure for an industrial robot chassis, including a narrow space 1 located inside the chassis. The narrow space 1 is a hexahedron with all six sides being rectangular. The height of the hexahedron is greater than its width. Two plates arranged along the width direction of the narrow space 1 are an inner plate and an outer plate. The inner plate is located between the outer plate and the inner cavity of the chassis.

[0040] Both the outer and inner side panels are provided with air inlets and air outlets. The two air inlets are staggered in the height direction, and the two air outlets are staggered in the height direction. A heat exchange mechanism is also provided in the narrow space 1, which is sealed in the narrow space 1 and spaced apart from the two air inlets.

[0041] The air outlet 5 on the inner side plate is located above the air outlet on the outer side plate, and the air inlet 4 on the inner side plate is located above the air outlet on the inner side plate. The air outlet on the outer side plate and the air inlet on the inner side plate are directly opposite each other, and the heat exchange plate 6 is located above the air inlet on the outer side plate.

[0042] The fan connected to the outside is located in the narrow space 1, and the fan connected to the inner cavity of the chassis is located inside the inner cavity of the chassis.

[0043] The narrow space 1 is also sealed with a heat exchange mechanism with two air inlets spaced apart. The heat exchange mechanism slides along the air inlet direction.

[0044] The heat exchange mechanism includes a heat exchange plate 6 and a support frame connecting the heat exchange plate 6 and the elongated space 1. The support frame and the heat exchange plate 6 are sealed within the elongated space 1.

[0045] The support frame includes an upper support plate connected to the upper end of the heat exchange plate 6 and a lower support plate 8 connected to the lower end of the heat exchange plate 6. The lower support plate 8 is an inclined plate that is inclined from the outside to the inside and from top to bottom. The bottom end of the lower support plate 8 is fixed with a sliding block 7 that is slidably connected to the inner side plate along the sliding direction of the heat exchange plate 6. The upper support plate extends to the top plate of the elongated space 1. A sealing ring is provided on the circumferential surface of the heat exchange plate 6 to seal and connect with the side wall of the elongated space 1. A sealing strip is also provided between the upper support plate and the lower support plate 8 and the corresponding side wall of the elongated space 1.

[0046] The narrow space 1 is equipped with a sealing ring 12 that mates with the heat exchange plate 6, the upper support plate, and the lower support plate 8. The sealing ring 12 has a rectangular cross-section. The lengths of the heat exchange plate 6, the upper support plate, and the lower support plate 8 are adapted to the length of the narrow space 1. By using the sealing ring 12 and the sealing strip, and the sealing ring 12 and the sealing ring, the heat exchange plate 6, the upper support plate, and the lower support plate 8 are all interference-fitted with the narrow space 1, and a sealing effect is achieved. At the same time, the sliding block 7 is also sealed and slidably connected inside the sealing ring 12.

[0047] A limiting post 9 extending to the outside is fixedly connected to the center of the heat exchange plate 6. The limiting post 9 has limiting holes arranged along the sliding direction of the heat exchange plate 6. A limiting pin 10 inserted into the limiting hole is provided on the outer side plate. A limiting seat 11 that cooperates with the limiting pin 10 is also provided on the outer side plate.

[0048] The heat exchange plate 6 has a heat exchange cavity inside, and an air inlet elongated hole communicating with the heat exchange cavity is opened on the bottom surface of the heat exchange plate 6. An air outlet elongated hole communicating with the heat exchange cavity is opened on the outer side surface of the heat exchange plate 6.

[0049] The heat exchange cavity is also provided with several heat exchange columns 13 that connect the outer and inner sides of the heat exchange cavity.

[0050] Specifically, attached Figure 2 The horizontal direction represents the width of the narrow space, and the vertical direction represents the height of the narrow space.

[0051] In this embodiment, the width of the heat exchange space on both sides of the heat exchange plate 6 is adjusted by adjusting the position of the support frame and the heat exchange plate 6. Since the outdoor temperature is different in summer and winter, the fan power needs to be increased in summer to dissipate heat quickly, while the outside temperature is low in winter and the heat exchange is relatively sufficient. Therefore, under the condition that the fan output power is stable, in summer, the outside air has less cold air, which causes the heat exchange plate 6 to move outward, reducing the heat exchange space on the outside and increasing the heat exchange space on the inside. As a result, the air velocity in the outer heat exchange space increases, and the fast-flowing air quickly carries away the heat from the heat exchange plate 6. The air velocity in the inner heat exchange space is low, so that the inner air can fully exchange heat with the heat exchange plate 6, thereby improving the heat exchange efficiency.

[0052] Conversely, in winter, the large amount of cold air from the outside causes the heat exchange plate 6 to move inward, reducing the heat exchange space on the inside and increasing the heat exchange space on the outside. As a result, the air velocity in the inner heat exchange space increases, thus achieving rapid heat exchange, while the air velocity in the outer heat exchange space is small, allowing the outer air to fully exchange heat with the heat exchange plate 6, thereby improving heat exchange efficiency.
