Abstract

The utility model relates to the field of eddy current retarder coil technology and discloses a solenoid coil framework with high heat dissipation efficiency. The solenoid coil framework comprises an upper frame body, a coiling body and a lower frame body. The coiling body is fixed between the upper frame body and the lower frame body; the external diameters of the upper frame body and the lower frame body are greater than the external diameter of the coiling body; and the upper frame body is provided with heat dissipation holes along the periphery. The solenoid coil framework is simple in structure and easy to use. The heat dissipation holes disposed in the upper frame body and the lower frame body guarantee effective heat dissipation, so that the heat dissipation efficiency is improved.

Description

The high-cooling property electromagnetic coil skeleton
Technical field
The utility model relates to current vortex retarder Coil technique field, is a kind of electromagnetic coil skeleton of high heat dispersion.
Background technology
Current vortex retarder generally is comprised of stator, rotor and fixed support.During retarder work, energising produces magnetic field in the stator coil, and rotor rotates with power transmission shaft.The magnetic line of force that the rotor cutting stator produces, thereby at the Vorticose induced current of the inner generation of rotor disk.Like this, stator will apply an electromagnetic force that hinders rotor to rotor, thereby produces braking moment.Simultaneously, eddy current has the rotor disk internal circulation of certain resistance, because the thermal effect of resistance can be electric energy conversion heat energy, like this, the kinetic energy of Vehicle Driving Cycle just finally is converted into heat energy by electromagnetic induction and resistance heating and distributes.The current vortex retarder coil is because large electric current long-term work so that coil electromagnetism conductor overheating amount is large, is had relatively high expectations to heat radiation, and there is the problem of poor radiation in present electromagnetic coil skeleton.
Summary of the invention
The utility model provides a kind of high-cooling property electromagnetic coil skeleton, has overcome the deficiency of above-mentioned prior art, and it can solve the problem that there is poor radiation in present electromagnetic coil skeleton.
The technical solution of the utility model is achieved like this: a kind of high-cooling property electromagnetic coil skeleton, comprise upper frame, winding body and lower frame, be fixed with winding body between upper frame and the lower frame, the external diameter of upper frame and lower frame circumferentially has louvre greater than the external diameter of winding body on upper frame.
Louvre is circumferentially arranged on the above lower frame.
Boss is arranged at the bottom of above lower frame.
The utility model is simple in structure, and is easy to use, and by at upper frame and lower frame louvre being set, the energy efficiently radiates heat has improved the efficient of heat radiation.
Description of drawings
Fig. 1 is that master of the present utility model looks sectional structure chart.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Coding among the figure is respectively: 1 is upper frame, and 2 is winding body, and 3 is lower frame, and 4 is louvre, and 5 is boss.
Embodiment
Extremely shown in Figure 2 such as Fig. 1, a kind of high-cooling property electromagnetic coil skeleton comprises upper frame 1, winding body 2 and lower frame 3, is fixed with winding body 2 between upper frame 1 and the lower frame 3, the external diameter of upper frame 1 and lower frame 3 circumferentially has louvre 4 greater than the external diameter of winding body 2 on upper frame 1.By circumferentially there being louvre 4 can greatly improve radiating efficiency.
To shown in Figure 2, louvre 4 is arranged circumferentially on the lower frame 3 such as Fig. 1.Like this, can improve better radiating efficiency; According to needs are installed, in the bottom of lower frame 3 boss 5 is arranged.
