[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-6 , the present invention provides a technical solution: an electromechanical equipment balanced heat dissipation device, including: a PLC control cabinet 1 with a hollow interior and an open front end, a compressor 2 is installed at the lower end inside the PLC control cabinet 1, two first heat dissipation fans 3 are installed on the lower surface of the PLC control cabinet 1, a heat dissipation copper pipe 4 is connected to the lower end of the PLC control cabinet 1 and below the first heat dissipation fans 3, the front end of the heat dissipation copper pipe 4 is connected to the front side output end of the compressor 2, the rear end of the heat dissipation copper pipe 4 extends to the inside of the PLC control cabinet 1 on the right side, an expansion valve 5 is connected in the pipeline on the right side of the heat dissipation copper pipe 4, radiators 6 are connected in an array inside the PLC control cabinet 1, cooling pipelines 7 are connected in an array on the left side of the heat dissipation copper pipe 4, the cooling pipelines 7 extend to the inside of the radiators 6, fans 8 are installed in an array on the left and right sides of the PLC control cabinet 1, the end of the cooling pipeline 7 is connected to a return pipeline 9, the return pipeline 9 extends to the inside of the PLC control cabinet 1, one end of the return pipeline 9 extends to the rear side input end of the compressor 2, and a refrigerant is filled in the heat dissipation copper pipe 4, the cooling pipeline 7 and the return pipeline 9.

[0026] During use, the compressor 2 is started. The compressor 2 compresses and pushes the refrigerant into the interior of the heat dissipation copper tube 4. At this time, the refrigerant is a high-temperature and high-pressure gas. The heat dissipation fan 3 blows on the surface of the heat dissipation copper tube 4 to help with cooling. At this time, the refrigerant at the end of the heat dissipation copper tube 4 is in a low-temperature and high-pressure state. When it enters the interior of the cooling pipe 7 through the expansion valve 5, it will turn into a low-temperature and low-pressure liquid. The PLC controller inside the PLC control cabinet 1 emits a large amount of heat, and this heat will be conducted to the radiator 6. The cooling pipe 7 is in contact with the radiator 6, and the cooling pipe 7 will absorb the heat of the radiator 6. At the same time, the fan 8 also helps the radiator 6 dissipate heat, thereby absorbing a large amount of the heat dissipated by the PLC controller. The refrigerant inside the cooling pipe 7 absorbs heat and is converted into a gaseous state at normal temperature and low pressure, and then enters the interior of the compressor 2 again to start a new cycle, helping to reduce the temperature inside the PLC control cabinet 1.

[0027] As Figures 1-4 shown, an embodiment of the present invention provides an implementation manner. Based on the above implementation manner, a temperature detector is installed inside the PLC control cabinet 1, and the PLC control cabinet 1 is electrically connected to the temperature detector.

[0028] Analyzing the above structure, it can be seen that the temperature detector inside the PLC control cabinet 1 detects the temperature inside the PLC control cabinet 1 and simultaneously transmits the temperature data to the display on the surface of the cabinet door of the PLC control cabinet 1, facilitating the viewing of the internal temperature.

[0029] As Figures 1-3 shown, an embodiment of the present invention provides an implementation manner. Based on the above implementation manner, protective net covers 21 are connected to the left and right sides of the fan 8.

[0030] Analyzing the above structure, it can be seen that the protective net covers 21 on the left and right sides of the fan 8 can prevent accidental contact with the fan 8.

[0031] As Figures 1-6 shown, an embodiment of the present invention provides an implementation manner. Based on the above implementation manner, heat sinks 22 are connected to the left and right sides inside the PLC control cabinet 1. The heat sinks 22 are wrapped around the outside of the cooling pipe 7, and the lower ends of the heat sinks 22 extend to the lower surface inside the PLC control cabinet 1. A second heat sink 23 is connected to the lower end of the PLC control cabinet 1, and the second heat sink 23 is wrapped around the outside of the heat dissipation copper tube 4.

[0032] Analyzing the above structure, it can be seen that the heat sinks 22 and the second heat sink 23 can increase the heat dissipation area of the heat dissipation copper tube 4 and the return pipe 9, helping the heat dissipation copper tube 4 and the return pipe 9 dissipate heat.

[0033] As Figures 1-4As shown in the figure, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, a water outlet channel 24 is connected to the lower end inside the PLC control cabinet 1 and below the heat sink 22, and the gap between the upper end of the water outlet channel 24 and the heat sink 22 is communicated.

[0034] Analyzing the above structure, it can be seen that during use, the temperatures of the radiator 6 and the heat sink 22 are relatively low. When they come into contact with the relatively high-temperature air outside, small water droplets will condense on the outside of the heat sink 22. These small water droplets will flow into the interior of the water outlet channel 24 through the gap between the radiator 6 and the heat sink 22. A discharge pipe is connected to the front end inside the water outlet channel 24, facilitating the management and outflow of water.

[0035] As Figures 1-4 shown in the figure, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, the inside of the PLC control cabinet 1 is filled with heat insulation cotton.

[0036] Analyzing the above structure, it can be seen that the heat insulation cotton filled inside the PLC control cabinet 1 can prevent the heat outside from entering the inside of the PLC control cabinet 1.

[0037] As Figures 1-6 shown in the figure, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, the heat sink 22, the second heat sink 23 and the radiator 6 are all made of aluminum.

[0038] Analyzing the above structure, it can be seen that the heat sink 22 and the radiator 6 are both made of aluminum, which has good thermal conductivity and can better absorb the heat of the PLC controller and the heat dissipation copper pipe 4.

[0039] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
