Quickly the heat of the fluid of higher temperature in fuel tank can be discharged in time for cooling fin 83, and it is extraneous to have further speeded up heat radiation oil box 8
Heat exchange between air, the heat dissipation that can in time generate flywheel.
It is arranged such, on the one hand, when vacuum heat dissipation flying wheel battery work, rotating part, such as the shaft 21 of motor 2, meeting
More heat is generated, and the lower end for the bearing rod 7 being connected with 2 shaft 21 of motor is located at the ball for the damping body 6 for storing fluid
In nest 61, and the fluid can be touched, so it can transfer heat to the fluid in fluid reservoir 5, and the fluid can follow
Circulation leads to the heat radiation oil box 8 outside shell 1, is taken out of with the heat that this can generate 2 shaft 21 of motor, avoids excessively high temperature
It spends and all parts of flying wheel battery is generated with the occurrence of damaging and may leading to machine breakdown.
On the other hand, the damping body 6 of setting can relative to 5 generation activity of fluid reservoir, thus one, when flywheel 3 occurs
When vibration, fluid, when rotor oscillation is transmitted to damping body 6 by bearing rod 7, damping body are full of between damping body 6 and fluid reservoir 5
6 generation activities, the oil film in the gap between spherical surface and ball-and-socket 61 to periodically squeeze bearing rod 7, change the oil film
Pressure is distributed, this process has dissipated the vibrational energy of flywheel, is bestirred oneself use to play resistance.The activity of damping body 6 is eventually led to
Oil liquid temperature increases, and is converted into heat.
The environment in fluid reservoir 5 in shell 1 is similarly vacuum environment, can take a variety of methods will be under vacuum state
The fluid in fluid and external heat radiation oil box 8 in fluid reservoir 5 is circulated, as long as the fluid in fluid reservoir 5 is led to
It crosses and is swapped with the fluid in heat radiation oil box 8, the heat in flying wheel battery can be taken out of.Specifically, oil inlet pipe 81 and/
Or flowline 82 is equipped with oil well pump 9.
In present embodiment, further, using scheme as shown in Figure 1, i.e., in fluid reservoir 5 and heat radiation oil box 8
Between oil well pump 9 is set, in the specific implementation method, the vacuum degree in fluid reservoir 5 is more than the vacuum degree in heat radiation oil box 8, institute
With the entrance of oil well pump 9 connects fluid reservoir 5, and the outlet of oil well pump 9 connects heat radiation oil box 8, will be in fluid reservoir 5 with oil well pump 9
Fluid pumps in heat radiation oil box 8, and since the vacuum degree in fluid reservoir 5 is more than the vacuum degree in heat radiation oil box 8, so, it dissipates
Fluid in deep fat case 8 is arrived by the way that flowline 82 is flowable in fluid reservoir 5.
How the import export of oil well pump 9 is connected with fluid reservoir 5 and heat radiation oil box 8, depends on fluid reservoir 5 and heat radiation oil box
The size of vacuum degree in 8, for example, in another specific implementation mode, when the vacuum degree in fluid reservoir 5 is less than heat dissipation oil
When vacuum degree in case 8, the entrance of oil well pump 9 connects heat radiation oil box 8, and the outlet of oil well pump 9 should connect fluid reservoir 5, with pumping
Oil pump 9 pumps to the fluid in heat radiation oil box 8 in fluid reservoir 5, since the vacuum degree in fluid reservoir 5 is less than in heat radiation oil box 8
Vacuum degree, so, fluid in accumulator 5 is flowable in heat radiation oil box 8 by flowline 82.
Realize that fluid carries out therebetween in such a way that oil well pump 9 is set between fluid reservoir 5 and heat radiation oil box 8
It circulates, the set-up mode is simple, implementation easy to operation.
In present embodiment, the end spherical surface of bearing rod 7 is equipped with the helicla flute 71 that can accommodate fluid, when bearing rod 7
When running at high speed, 71 oil is spilled over in the gap between spherical surface and ball-and-socket 61 in helicla flute, to supplement the fluid in gap.

62.Thus, which damping body 6 can be relative to 51 activity of fixed seat by curved protrusion 62, but curved indentations are not departed from, this sets
Mode is set, is had the advantages of simple structure and easy realization.
Further, the bottom of damping body 6 is fixed with sphere, and a part for sphere constitutes curved protrusion 62, and curved surface is recessed
Slot is also spherical groove, i.e. ball-and-socket, and curved protrusion 62 coordinates with spherical groove so that damping body 6 can be put relative to fixed seat 51
Dynamic and rotation.
In present embodiment, as shown in Fig. 2, the inner wall of fluid reservoir 5 is equipped with fixed part 52, the longitudinal section of fixed part 52
With the positive U-lag that can accommodate fluid, damping body 6 includes ontology 63 and the limiting device for being located at 63 outside of ontology, limiting device
Including the first locating part 64 extended from top to bottom, the first locating part 64 is inserted in formation gap in the positive U-lag of fixed part 52 and matches
It closes.First locating part 64 is limited in positive U-lag, thus, which fixed part 52 can by way of limiting the first locating part 64
The significantly swing of damping body 6 is limited, damping body 6 is can avoid and the occurrence of unbalance occurs because significantly swinging.
Further, as shown in Fig. 2, limiting device further includes the second locating part 65 extended from top to bottom and connection first
The transverse arm of the upper end of the upper end of locating part 64 and the second locating part 65, the first locating part 64, the second locating part 65 and transverse arm it is vertical
Section constitution inverted U-channel, positive U-lag are inserted in close to the wall of damping body 6 in inverted U-channel and form clearance fit from bottom to top.
In the present embodiment, limiting device is sleeved on the outside of the ontology 63, is realized and ontology 63 by being interference fitted
Fixed, certainly, in other embodiments, limiting device can also be integrally formed with ontology.Second locating part 65 to the first limits
Closer to the ontology 63, lower part to the bottom diameter of ontology 63 reduces part 64 so that the outer wall of the ontology 63 and described the
Gap is formed between two locating parts 65.In this way, it is " W " to form longitudinal section between fixed seat 51, limiting device and ontology 63
The gap of shape is full of fluid between gap, and in the present embodiment, fluid is common damping oil.
By the set-up mode, when damping body 6 vibrates, the first locating part 64 and the second locating part 65 and fixed part 52
Mutual cooperation can limit the generation of damping body 6 and significantly vibrate, and then avoid leading to the unbalance situation of flywheel because of violent oscillatory motion
Generation.
Positive U-lag and inverted U-channel can be the annular for the circumferentially extending for being parallel to the ontology, or can also fixed part
52 set there are two the positive U-lag of the axisymmetrical relative to ontology 63, and ontology 63 sets the axis pair there are two relative to ontology 63
The inverted U-channel claimed, can limit the rotational steps of damping body in this way.
In present embodiment, as shown in Fig. 2, the lower part of the ontology 63 of damping body 6 is equipped with perforative horizontal channel 66,
The ontology 63 of damping body 6 is additionally provided with the Vertical Channel 67 coaxial with ontology 63, and the upper end of Vertical Channel 67 is communicated with ball-and-socket 61, erects
The lower end of straight channel 67 is connected to horizontal channel 66.The setting in channel can make the fluid in ball-and-socket 61 be rapidly performed by and dissipate
Fluid in deep fat case 8 swaps flowing, and the fluid in ball-and-socket 61 connects the bearing rod 7 of 2 shaft 21 of motor, such as
