Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of eddy current retarder cooling, in particular to an eddy current retarder rotor cooling device. Background Art
[0002] When the retarder is working, the rotor will rotate at high speed with the transmission shaft, cutting the magnetic lines of force generated by the stator, thereby generating a vortex-shaped induced current inside the rotor disk. In this process, due to the thermal effect of the resistor, the electrical energy will be converted into thermal energy, causing the rotor temperature to rise. At this time, the rotor cooling device of the eddy current retarder is a key component. Its main function is to reduce the heat generated by the rotor during operation, thereby ensuring the normal operation of the retarder and extending its service life.
[0003] After searching, the patent with announcement number CN202260968U discloses an eddy current retarder rotor cooling device, and its content records that "at least one fine water mist nozzle aligned with the outer inner ring of the rotor is fixed on the stator, and the fine water mist nozzle is connected to the pressure water bottle through a conduit and an electromagnetic valve. The beneficial effect of the utility model is to improve the cooling efficiency of the eddy current retarder rotor, improve the safety of vehicle driving, and solve the problem that the original eddy current retarder cannot stop immediately after going down a long slope..." From the above, it can be seen that the cooling device of the patent uses water spraying, and water has good conductivity. If water is sprayed directly on the rotor when the power is on, it may cause a short circuit, thereby damaging the power supply or the retarder. At the same time, although water spraying can quickly reduce the temperature, it will also cause the internal components of the retarder to experience drastic temperature changes. This rapid temperature change may cause deformation, cracking or failure of the components, and there are certain shortcomings. Utility Model Content

[0027] Specifically, the eddy current retarder body 100 includes a stator 101, a left rotor 102 arranged on the left side of the stator 101, and a right rotor 103 arranged on the right side of the stator 101. The stator 101 is provided with a mounting hole 104, and the mounting hole 104 is used to install the first annular tube 201 and the second annular tube 202 so as to replace the first annular tube 201 and the second annular tube 202.
[0028] Specifically, the cooling assembly 200 includes a first annular tube 201 arranged on the left side of the stator 101, a second annular tube 202 arranged on the right side of the stator 101, a first delivery pipe 203 arranged at the top of the first annular tube 201 and the second annular tube 202, a second delivery pipe 204 arranged at the bottom of the first annular tube 201 and the second annular tube 202, a stud 205 arranged on the inner side of the first annular tube 201 and the second annular tube 202 and a nut 206 threadedly connected to the stud 205. The coolant is delivered to the first annular tube 201 and the second annular tube 202 through the second delivery pipe 204. After delivery, the coolant can quickly reduce the temperature of the rotor by absorbing heat for use. At the same time, the nut 206 can be rotated until it is completely separated from the stud 205. After separation, the first annular tube 201 and the second annular tube 202 can be directly disassembled for replacement and maintenance.
[0029] Specifically, the water tank 300 is arranged on the right side of the first delivery pipe 203, an injection pipe 301 is arranged on the top of the water tank 300, and a discharge pipe 302 is arranged at the front end of the water tank 300. The injection pipe 301 and the discharge pipe 302 are both threadedly connected with sealing covers. A certain amount of coolant can be injected into the water tank 300 through the injection pipe 301, and the coolant can be discharged through the discharge pipe 302, so that the coolant can be replaced regularly.
[0030] Specifically, the circulation component 400 is arranged on the right side of the water tank 300. The circulation component 400 includes a third delivery pipe 401 arranged on the right side of the water tank 300 and a circulation pump 402 arranged on the third delivery pipe 401. The operation of the circulation pump 402 can be controlled. The operation of the circulation pump 402 can transport the coolant in the water tank 300 through the third delivery pipe 401 and the second delivery pipe 204 to the first annular pipe 201 and the second annular pipe 202, and then transport it to the water tank 300 through the first delivery pipe 203, so as to form a circulating coolant for cooling.
[0031] Specifically, the radiator 500 is fixedly connected to the circulation component 400. The radiator 500 is composed of a plurality of heat sinks and pipes. The pipes can transport coolant, and the heat can be quickly dissipated through the heat sinks.
[0032] Specifically, the air cooling component 600 is arranged on the radiator 500, and the air cooling component 600 includes a fixing plate 601 arranged at the front end of the radiator 500 and a fan 602 arranged on the fixing plate 601. The fan 602 can quickly take away the heat of the radiator 500 to quickly cool it down.
[0033] The working principle and use process of the utility model are as follows: when in use, the circulation pump 402 of the circulation component 400 can be controlled to operate. The circulation pump 402 can operate to transport the coolant in the water tank 300 through the third delivery pipe 401 and the second delivery pipe 204 to the first annular pipe 201 and the second annular pipe 202, and then transport it to the water tank 300 through the first delivery pipe 203, so as to form a circulating coolant. During the circulation process, the coolant in the first annular pipe 201 and the second annular pipe 202 can quickly reduce the temperature of the rotor by absorbing heat, so as to facilitate use. At the same time, the heat on the coolant can be quickly dissipated by the thermal conductivity of the radiator 500, and then the heat of the radiator 500 can be quickly taken away by the fan 602, so as to quickly cool down. After that, the nut 206 can be rotated to completely disengage from the stud 205. After disengagement, the first annular pipe 201 and the second annular pipe 202 can be directly disassembled for replacement and maintenance. Finally, a certain amount of coolant can be injected into the water tank 300 through the injection pipe 301, and the coolant can be discharged through the discharge pipe 302, so as to regularly replace the coolant.
