As shown in Figure 2,3, MRI body coils construction package disclosed by the invention, including body coil 1 and outer barrel 13, body coil 1
Including inner cylinder 11 and electronic component 12, electronic component 12 is set on 11 lateral wall of inner cylinder, and outer barrel 13 is sleeved on outside inner cylinder 11, outer barrel
Heat dissipation channel is formed between 11 outer wall of 13 inner walls and inner cylinder, the air inlet 2 of heat dissipation channel is located at one end of body coil 1, and heat dissipation is logical
The air outlet 3 in road is located at the other end of body coil 1.When specifically used, blown toward at air inlet 2 by ajutage, ajutage
Wind turbine is set at air intake vent, and the outlet of ajutage is connected with air inlet 2.Air quickly flows in heat dissipation channel, takes away rapidly
The heat that electronic component 12 generates when working improves component life, reduces the sense of discomfort of tested patient.
One end of inner cylinder 11 is equipped with ring flange A4, and the other end of inner cylinder 11 is equipped with ring flange B5, ring flange A4 and ring flange
Between outer barrel 13 and inner cylinder 11, air inlet 2 is axial to be set on ring flange A4 B5, and air outlet 3 is axial to be set on ring flange B5；
It is circumferential on ring flange A4 to be equipped at least two air inlets 2 at equal intervals, it is circumferentially equipped at least two outlet air at equal intervals on ring flange B5
Mouth 3.
11 lateral wall of inner cylinder be equipped with spacer flanger disk 6, spacer flanger disk 6 with positioned at ring flange A4 and ring flange B5 it
Between, electronic component 12 is between spacer flanger disk 6 and ring flange B5.As shown in figure 4, in spacer flanger disk 6 and ring flange A4
It is equipped with air flow annular cover plate 8, spacer flanger disk 6 constitutes an air flow chamber with air flow annular cover plate 8.
It is tiltedly installed with air flow guide plate 9, air flow between air flow intracavitary spacer flanger disk 6 and ring flange A4
Guide plate 9 is equipped at least three at equal intervals around inner cylinder 11；Each air flow guide plate 9 corresponds to one on spacer flanger disk 6
The number of a air flow outlet 7, air flow outlet 7 is more than the number of air inlet 2.Preferably, air flow guide plate 9 has 8
It is a.There are certain angle, 9 one end of air flow guide plate to be connect with spacer flanger disk 6 between air flow guide plate 9 and spacer flanger disk 6
It touches, 9 other end of air flow guide plate has interval with ring flange A4.
It, can be equably from 8 air after air enters air flow chamber from two air inlets 2 because of above-mentioned shunting function
7 outflow of shunting outlet.Because being cased with outer barrel 13 outside inner cylinder 11, one is just formed between 11 outer wall of 13 inner wall of such outer barrel and inner cylinder effectively
Heat dissipation channel, air are just taken away its heat distributed by electronic component 12, are finally led to after 7 outflow of air flow outlet
The air outlet 3 crossed on ring flange B5 is discharged to scanning room.In addition, outer barrel 13 is sleeved on outside inner cylinder 11, make external environment direct
It contacts with electronic component 12, plays an important role to protection electronic component 12.As shown in Figure 3,4, electricity has been covered with it on 11 outer wall of inner cylinder
Subcomponent 12 is easy to encounter if outside does not have protection mechanism during carrying and installation, causes product failure or quality
It reduces.
In magnetic resonance imaging patient, since gradient coil 17 vibrates strong and causes very big noise.If by body coil 1
It is placed directly on gradient coil 17, body coil 1 certainly will be caused to vibrate, influence image quality.As shown in Fig. 2, by 11 both ends of inner cylinder
Bottom extend to form extension 14, coil mounting bracket 15 is installed, then as shown in Figure 5,6 on extension 14, passes through line
Body coil 1 is directly installed on magnet 10 by circle mounting bracket 15 and fixed structure 18, coil mounting bracket 15 and fixed structure
18 is affixed, and fixed structure 18 and 10 end face of magnet are affixed, be maintained for before such body coil 1 and gradient coil 17 it is hollow be isolated,
Body coil 1 will be reduced by the vibration of gradient coil 17；Meanwhile the noise that gradient coil 17 generates is also mainly from body coil
Inner tube wall is spread out of.
Respectively there are one bed board guide rails 16 for installation for 11 inner wall of inner cylinder or so.Wherein, bed board support is installed on bed board guide rail 16
Wheel 161 and bed board position-limited wheel 162, the axis of bed board support wheel 161 are parallel with horizontal plane.The axis and water of bed board position-limited wheel 162
Plane is vertical.Bed board position-limited wheel 162 avoids bed board double swerve while reducing frictional force.By bed board guide rail 16 and body coil 1
Inner cylinder 11 combines together, then bed board support wheel 161 and left and right position-limited wheel are installed on bed board guide rail 16, and body coil 1 is again compatible
Bed board guide rail function reduces cost, is easily installed, and bed board guide rail 16 is very close to each other with body coil 1 in this way, can effectively avoid
The small metalliferous material sucking such as coin.
