[0002] The commonly used box-type exciters in the current market, with their excellent sealing design, effectively avoid the problem of axial oil leakage, thus ensuring continuous and stable operation for a long time. However, this long-term uninterrupted working mode also brings certain challenges: the temperature of the exciter box will gradually increase, and this temperature change often has an adverse impact on the normal operation of the exciter. Especially in those working scenarios where the ambient temperature is already relatively high, it becomes particularly difficult to reduce the temperature of the exciter box. This high-temperature state may not only cause the exciter to be forced to stop due to overheating, affecting production efficiency, but also pose potential safety hazards, possibly leading to equipment failures or safety accidents. For this reason, we propose an automatic temperature reduction structure for an exciter. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , the present invention provides a technical solution: an automatic temperature reduction structure for an exciter, including a gearbox 1. A heat conduction plate 4 is provided on the upper surface of the gearbox 1. One side of the heat conduction plate 4 is arranged inside the gearbox 1, and the other side of the heat conduction plate 4 protrudes above the gearbox 1. The heat conduction plate 4 is made of a material with high heat conduction efficiency, such as aluminum alloy, and can quickly conduct the heat generated in the gearbox 1 during the operation of the exciter to the outside, thereby improving the heat dissipation effect.

[0020] A cavity 5 is formed inside the heat conduction plate 4. An absorbent filling layer 6 and a heat conduction device are arranged in the cavity 5. The filling layer 6 can be selected as common phase change materials, such as paraffin or inorganic phase change materials of crystal hydrates. It can absorb heat and undergo a phase change when the temperature rises, thereby storing the heat, and release the stored heat when the ambient temperature drops or the equipment load decreases, realizing heat dissipation. In this way, the phase change material can effectively control the temperature of the equipment, improve the heat dissipation efficiency, cooperate with the heat conduction device to achieve rapid automatic temperature reduction, avoid the situation that the exciter is forced to stop due to overheating and the possible equipment failures or safety accidents caused thereby, ensure the production efficiency, and eliminate potential safety hazards.

[0021] In a preferred technical solution, the heat conduction device includes a heat conduction tube 7 arranged inside the cavity 5. Both ends of the heat conduction tube 7 penetrate through the upper surface of the heat conduction plate 4 and are respectively communicated with a liquid inlet tube 8 and a liquid return tube 9. The liquid inlet tube 8 and the liquid return tube 9 are both communicated with a circulating coolant tank 10 arranged outside the gearbox 1. The liquid inlet tube 8 and the liquid return tube 9 are both connected to a pump arranged in the circulating coolant tank 10. The pump connected to the liquid inlet tube 8 is used to send the cooled coolant in the circulating coolant tank 10 into the heat conduction tube 7 in the cavity 5 through the liquid inlet tube 8 for heat absorption and temperature reduction. The pump connected to the liquid return tube 9 is used to pump the coolant with increased temperature after heat absorption in the heat conduction tube 7 back to the circulating coolant tank 10 for cooling. By circulating the coolant to take away the heat of the heat conduction plate 4, rapid temperature reduction can be achieved, further improving the heat dissipation effect, and avoiding the situation that the exciter is forced to stop due to overheating and the possible equipment failures or safety accidents caused thereby.

[0022] Inside the gearbox 1, a temperature sensor electrically connected to the controller 11 is provided. The controller 11 can be arranged on the outer surface of the circulating coolant tank 10, and it can be an optional common PLC controller, such as a PLC controller of the Siemens S7-200 series. The controller 11 is electrically connected to an external power supply and is used to control the switch and power of the pump in the circulating coolant tank 10, etc. The temperature sensor detects the temperature inside the gearbox 1 and transmits a corresponding signal to the controller 11. The controller 11 judges whether the temperature reaches the corresponding value according to a preset program, thereby turning on the pump or adjusting the power of the pump to adjust the circulation speed of the coolant, and then intelligently controlling the temperature inside the gearbox 1 to achieve the effect of automatic cooling, greatly improving the degree of automation.

[0023] In a preferred technical solution, the heat conduction tube 7 is a plurality of "S"-shaped pipes connected end to end. The filling layer 6 is filled in the gap between the heat conduction tube 7 and the inner wall of the cavity 5. The heat conduction tube 7 is set in an "S" shape to extend its length in the cavity 5 and the contact area with the filling layer 6, thereby improving its heat absorption efficiency and further improving the cooling effect.

[0024] In an optional technical solution, a plurality of semiconductor refrigeration chips 12 are evenly arranged on the outer surface of the circulating coolant tank 10. The semiconductor refrigeration chips have the characteristics of fast response and efficient regulation, can reduce the temperature in a short time, are suitable for use in the case where the vibrator needs to dissipate heat quickly, and can dissipate heat emergently, ensuring the safe operation of the equipment.

[0025] Further optionally, a fan bracket 13 is installed on the outer surface of the circulating coolant tank 10, and a cooling fan 14 is installed on the fan bracket 13. The cooling fan 14 is arranged outside the semiconductor refrigeration chip 12. Through the cooling fan 14, the heat generated by the semiconductor refrigeration chip 12 and the heat of the heated coolant in the circulating coolant tank 10 can be quickly discharged into the external air, further improving the cooling efficiency.

[0026] The cooling fan 14 and the semiconductor refrigeration chip 12 are also electrically connected to the controller 11, and the controller 11 automatically controls the switch of the cooling fan 14 and the semiconductor refrigeration chip 12 according to the temperature detected by the temperature sensor.

[0027] In a preferred technical solution, a plurality of mounting blocks 15 are evenly arranged on the outer surface of the circulating coolant tank 10. Mounting holes 16 are opened at corresponding positions on the side surface of the mounting block 15 and the outer surface of the gearbox 1 for installing fixing bolts. The circulating coolant tank 10 is installed outside the vibrator through fixing bolts, etc., and can be flexibly installed according to the use needs without affecting transportation and normal use conditions, etc.

[0028] A further preferred technical solution is that the liquid inlet pipe 8 and the heat conduction pipe 7, and the liquid return pipe 9 and the heat conduction pipe 7 are both connected through a connector 17. The connector 17 is a commonly used connector for connecting two pipelines, which is convenient for disassembling and assembling the circulating coolant tank 10. In occasions with higher cooling requirements, the circulating coolant tank 10, the liquid inlet pipe 8 and the liquid return pipe 9, etc. are installed; in cases where the cooling requirement is lower, it is not necessary to install the circulating coolant tank 10, the liquid inlet pipe 8 and the liquid return pipe 9, etc. The heat conduction pipe 7 can be sealed or filled with a filling layer 6 and then sealed, which is applicable to different usage scenarios.

[0029] An optional technical solution is that there are two heat conduction pipes 7, liquid inlet pipes 8, liquid return pipes 9 and circulating coolant tanks 10. The two sets of heat conduction pipes 7, liquid inlet pipes 8, liquid return pipes 9 and circulating coolant tanks 10 are symmetrically arranged on both sides of the gearbox 1. By setting two sets of circulating coolant tanks 10, the cooling efficiency can be further improved. At the same time, it is also possible to determine whether to open one or two heat conduction devices for automatic cooling according to the temperature inside the gearbox 1, which further improves the applicability and can save energy when the cooling demand is low, being beneficial to energy conservation and environmental protection.

[0030] A preferred technical solution is that two protective covers 2 are symmetrically arranged on both sides of the gearbox 1 for protecting the eccentric block, the rotating shaft, etc.; a plurality of ventilation holes 3 are evenly opened on the outer surface of the protective cover 2 for dissipating heat at the eccentric block.
