DETAILED DESCRIPTION

[0024] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] like Figure 1 and Figure 2 The structure shown is a heat dissipation device for an industrial robot control cabinet, comprising a circuit amplifier, a heat sink 2, a fan 3 and a rotating motor, wherein the circuit amplifier, the heat sink 2 and the fan 3 are all arranged inside a control cabinet housing 1, the rotating motor drives the fan 3 to rotate, the circuit amplifier controls the voltage of the rotating motor, thereby controlling the rotating motor speed, the heat sink 2 is connected to the inner wall of the control cabinet housing 1, the corresponding two side surfaces of the control cabinet housing 1 are respectively connected with an air inlet plate 4 and an air outlet plate 6, the surfaces of the air inlet plate 4 and the air outlet plate 6 are both provided with a plurality of penetrating small holes, the fan 3 is arranged between the heat sink 2 and the air inlet plate 4, the surface of the heat sink 2 is connected with a thermistor 7 for monitoring the temperature of the heat sink 2, and the circuit amplifier is connected to the rotating motor through wires.

[0027] Specifically, multiple groups of fans 3 are provided, and the multiple groups of fans 3 are arranged in a linear array.

[0028] In actual use, the heat generated inside the control cabinet is absorbed by the heat sink 2, and the thermistor 7 monitors the temperature of the heat sink 2. When the temperature rise is detected, the resistance value of the thermistor 7NTC decreases. At this time, the current of the constant low-voltage circuit increases, and then the voltage of the rotating motor is amplified by the circuit amplifier, thereby accelerating the speed of the fan 3 and allowing the heat sink 2 to dissipate heat quickly. As the temperature of the heat sink 2 decreases, the resistance value of the thermistor 7NTC increases, and the circuit amplifier reduces the voltage of the rotating motor, thereby reducing the speed of the fan 3. When the temperature of the heat sink 2 rises again, the above steps are repeated to adjust the speed of the fan 3. When the temperature is constant, the speed of the fan 3 gradually becomes constant.

[0029] It should be noted that the fan 3 draws the wind outside the control cabinet into the interior of the control cabinet through the small holes opened on the air inlet plate. After passing through the heat sink 2 and the brake resistor 5, the wind is discharged from the small holes opened on the air outlet plate 6. This setting can prevent heat from affecting the life of the fan 3.

[0030] It should be further explained that the heat dissipation method provided by this solution can adjust the rotation speed of the electric cabinet fan 3 and monitor the heat dissipation of the electric cabinet, which can not only improve the efficiency of electric energy use, but also avoid failures caused by untimely heat dissipation.

[0031] Furthermore, a brake resistor 5 is provided between the heat sink 2 and the air outlet plate 6 , and the brake resistor 5 is connected to the rotating motor through an electric wire. The number of the brake resistors 5 corresponds to the number of the fans 3 .

[0032] It should be noted that when the rotating motor rotates too fast, the rotating motor can be braked by the brake resistor 5 .

[0033] Furthermore, an integrated module is arranged inside the control cabinet housing 1. Specifically, the integrated module includes a main control board, a power module, an I / O module, a communication module, etc. The heat sink 2 includes a transverse heat conductive sheet 21 and a plurality of groups of longitudinal heat conductive sheets 22. The integrated module is located above the transverse heat conductive sheet 21. The plurality of groups of longitudinal heat conductive sheets 22 are connected to the lower surface of the transverse heat conductive sheet 21 and are arranged in a linear array. The array direction is the same as the array direction of the fan 3. The wind blown out by the fan 3 flows between the plurality of groups of longitudinal heat conductive sheets 22, thereby reducing the temperature of the heat sink 2.

[0034] It should be noted that the transverse heat conducting plate 21 divides the interior of the control cabinet into two layers, an upper layer and an lower layer. By means of a special design in which the integrated module is arranged in the upper layer and the heat dissipation module is arranged in the lower layer, a special structure with distinct layers is formed in the control cabinet. This structure can not only meet the heat dissipation requirements, but also facilitate future maintenance. In this embodiment, the upper and lower layers form separate spaces. Due to the separation of the transverse heat conducting plate 21, when the fan 3 dissipates heat from the heat sink 2 in the lower layer, the heat will not flow to the upper layer. The size of the transverse heat conducting plate 21 is consistent with the cross-sectional size of the control cabinet shell 1.

[0035] It should be further explained that the heat sink 2 and the inner wall of the control cabinet shell can be connected in an overlapping manner. This connection method facilitates the replacement of the heat sink 2. Specifically, at least the corresponding two sides of the inner wall of the control cabinet shell 1 have overlapping plates protruding thereon. In order to enhance the stability of the heat sink 2, overlapping plates can also be provided on the other two sides of the control cabinet shell 1 as needed, so that the edge of the lower surface of the transverse heat conducting plate 21 is overlapped to the upper surface of the overlapping plate.

[0036] Example 2

[0037] This embodiment provides a heat dissipation device for an industrial robot control cabinet. On the basis of Embodiment 1, further improvements are made by adding an accelerating heat dissipation component 8 and a driving component 9. The driving component 9 cooperates with the accelerating heat dissipation component 8 to further dissipate heat from the heat sink 2 and accelerate the cooling speed of the heat sink 2. Specifically, Figures 3 to 7 In the structure shown, the accelerated heat dissipation component 8 and the driving component 9 are both arranged inside the control cabinet housing 1.

[0038] Furthermore, the accelerated heat dissipation component 8 includes a box body 81, a wiping plate 82, a wiping cloth 83 and a connecting plate 85. The wiping plates 82 are arranged on both sides of each group of longitudinal heat conductive plates 22. The length of the wiping plates 82 can just contact the inner walls on both sides of the box body 81. Multiple groups of the wiping plates 82 are connected to the surface of the connecting plate 85. The wiping cloth 83 is connected to the side surface of each group of wiping plates 82 close to the longitudinal heat conductive plates 22. The box body 81 is located below the heat dissipation fins 2 and is detachably connected to the inner bottom of the control cabinet housing 1. A notch 84 corresponding to the wiping plate 82 is opened on the upper surface of the box body 81. The inner wall of the notch 84 is connected to a door structure that can be opened and closed. The surface of the wiping plate 82 is connected to a driving component 9. The driving component 9 drives the wiping cloth 83 to move out of the notch 84 of the box body 81 and wipe the longitudinal heat conductive plates 22 for heat dissipation.

[0039] It should be noted that by dipping the rag 83 in water and wiping the surface of the longitudinal heat conductive sheet 22 , not only the heat dissipation effect of the longitudinal heat conductive sheet 22 can be accelerated, but also the surface thereof can be cleaned, thereby improving the heat transfer efficiency.

[0040] It should be further explained that the water loaded into the box 81 can be water at room temperature. An insulating layer can be set in the side wall of the box 81 to prevent the box 81 from contacting hot air and causing the temperature of the water in the box 81 to rise. In order to maintain the wiping and dust removal effect of the cloth 83, the water in the box 81 can be replaced regularly.

[0041] Furthermore, the driving assembly 9 includes a driving motor 91, a screw 92 and a limiting rod 93. The driving motor 91 is connected to the inner bottom of the control cabinet housing 1, the connecting plate 85 is connected to the surface of the screw 92, and the limiting rod 93 is fixedly connected to the inner bottom of the control cabinet housing 1 and passes through the connecting plate 85. The driving motor 91 drives the screw 92 to rotate and drives the wiping cloth 83 to move. The moving speed of the wiping cloth 83 should not be too fast and can be set according to actual conditions.

[0042] This embodiment provides a door structure, which not only defines a space, but also can squeeze the wet rag 83 to prevent the rag 83 from getting too wet and causing water to drip onto the surface of the box 81.

[0043] Specifically, the door structure is a water pressing assembly 10 for squeezing out the water absorbed by the wiping cloth 83 .

[0044] Furthermore, the water pressure assembly 10 includes a pressure plate 101 and a spring 102, and the inner wall of each group of grooves 84 is provided with a slide groove 103, the pressure plate 101 is slidably connected to the inner wall of the slide groove 103, one end of the spring 102 is connected to a side surface of the pressure plate 101 located in the slide groove 103, and the other end of the spring 102 is connected to the inner wall of the slide groove 103.

[0045] It should be noted that the lower end of the wiping plate 82 is arc-shaped, and the side where the pressure plate 101 contacts the wiping plate 82 is an inclined surface. When the wiping cloth 83 moves downward, the wiping plate 82 squeezes the pressure plate 101, so that the pressure plate 101 moves into the slide groove 103. As the wiping cloth 83 moves downward, the wiping cloth 83 will dip into the water in the box body 81. Due to the force of the spring 102, the pressure plate 101 is always pressed against the wiping plate 82. When the wiping cloth 83 moves upward, the pressure plate 101 cooperates with the inner wall of the notch 84 to squeeze the wiping cloth 83, and the excess water absorbed by the wiping cloth 83 is removed. At the same time, the pressing plate 101 cooperates with the inner wall of the groove 84 and the inner wall of the box body 81 to scrape off the water droplets on the side surface of the wiping plate 82. The lower part of the wiping plate 82 can be sprayed with some super-hydrophobic coatings to form a hydrophobic layer to prevent the water droplets from staying at the lower end of the wiping plate 82, and further prevent the dripping of the staying water droplets. In the scar embodiment, a super-hydrophobic coating is provided but not limited to this material. The coating is a hyperbranched poly (dihydroxymethyl butyric acid-glycidyl ester) / nano-SiO2 coating.

[0046] It should be further explained that the wiping cloth 83 can be a cooling towel, and the material of the wiping cloth 83 can also be cotton, fiber, etc. When the wiping cloth 83 is a cooling towel, the effect is best.

[0047] Example 3

[0048] like Figures 1 to 6As shown in the structure, this embodiment provides a heat dissipation device for an industrial robot control cabinet, including a circuit amplifier, a heat sink 2, a fan 3 and a rotating motor, wherein the circuit amplifier, the heat sink 2 and the fan 3 are all arranged inside a control cabinet housing 1, the rotating motor drives the fan 3 to rotate, and the circuit amplifier controls the voltage of the rotating motor, thereby controlling the speed of the rotating motor, the heat sink 2 is connected to the inner wall of the control cabinet housing 1, and the corresponding two side surfaces of the control cabinet housing 1 are respectively connected with an air inlet plate 4 and an air outlet plate 6, and the surfaces of the air inlet plate 4 and the air outlet plate 6 are both provided with a plurality of penetrating small holes, the fan 3 is arranged between the heat sink 2 and the air inlet plate 4, and the surface of the heat sink 2 is connected with a thermistor 7 for monitoring the temperature of the heat sink 2.

[0049] Furthermore, a brake resistor 5 is provided between the heat sink 2 and the air outlet plate 6 , and the brake resistor 5 is connected to the rotating motor through an electric wire.

[0050] Furthermore, an integrated module is arranged inside the control cabinet housing 1, and the heat sink 2 includes a transverse heat conductive sheet 21 and a plurality of groups of longitudinal heat conductive sheets 22. The integrated module is located above the transverse heat conductive sheet 21, and the plurality of groups of longitudinal heat conductive sheets 22 are connected to the lower surface of the transverse heat conductive sheet 21 and are arranged in a linear array.

[0051] Furthermore, the thermistor 7 is connected to the surface of the transverse heat conducting sheet 21 .

[0052] Furthermore, a heat dissipation acceleration component 8 is also provided inside the control cabinet housing 1 to accelerate the heat dissipation of the heat sink 2 .

[0053] Furthermore, the accelerated heat dissipation component 8 includes a refrigeration component, a box body 81, a wiper plate 82, a wiper cloth 83 and a connecting plate 85. The refrigeration component is arranged inside the box body 81. The refrigeration component can produce cold air and fill the box body 81 with cold air. The wiper plates 82 are arranged on both sides of each group of longitudinal heat conductive plates 22. Multiple groups of the wiper plates 82 are connected to the surface of the connecting plate 85. The wiper cloth 83 is connected to the side surface of each group of wiper plates 82 close to the longitudinal heat conductive plates 22. The box body 81 is located below the heat dissipation fins 2 and is detachably connected to the inner bottom of the control cabinet housing 1. A notch 84 corresponding to the wiper plate 82 is opened on the upper surface of the box body 81. The inner wall of the notch 84 is connected to a door structure that can be opened and closed. The surface of the wiper plate 82 is connected to a driving component 9. The driving component 9 drives the wiper cloth 83 to move out of the notch 84 of the box body 81 and perform heat exchange and heat dissipation on the longitudinal heat conductive plates 22.

[0054] The door structure in this embodiment may be an electrically controlled valve.

[0055] It should be noted that the refrigeration component can be ice cubes, a refrigerator or an ice maker. When the refrigeration component is ice cubes, no excess heat will be generated in the control cabinet. When the refrigeration component is a refrigerator, the inside of the box 81 can always have cold air. When the refrigeration component is an ice maker, the box 81 can be filled with water for use in conjunction with the ice maker. Specifically, the water is condensed into ice by the ice maker. After the water condenses into ice, the ice maker can be stopped and cold air is generated by the ice. When the ice cubes are completely melted, the ice maker is started again to make ice. In this case, the ice maker does not need to run all the time, and the box 81 can always have cold air.

[0056] In actual use, when the wiping cloth 83 is moved into the box body 81, the surface temperature of the wiping cloth 83 decreases, and then the wiping cloth 83 is moved to the surface of the longitudinal heat conductive plate 22, so that the wiping cloth 83 is successively attached to different parts of the longitudinal heat conductive plate 22 for heat exchange. After the temperature of the wiping cloth 83 rises, the wiping cloth 83 is moved into the box body 81 through the driving component 9.

[0057] It should be noted that the material of the wiping cloth 83 can be cotton, fiber, etc.

[0058] Furthermore, the driving assembly 9 includes a driving motor 91, a screw 92 and a limiting rod 93. The driving motor 91 is connected to the inner bottom of the control cabinet housing 1, the connecting plate 85 is connected to the surface of the screw 92, and the limiting rod 93 is fixedly connected to the inner bottom of the control cabinet housing 1 and passes through the connecting plate 85. The driving motor 91 drives the screw 92 to rotate and drives the wiping cloth 83 to move.

[0059] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
