Improve.
Wherein, the first fixed plate 1 plays liquid cooling plate 4 main positioning action, and the second fixed plate 2 plays liquid cooling plate 4 auxiliary
Positioning action is helped, therefore alternatively, the width of the second fixed plate 2 is less than the width of the first fixed plate 1, to meet positioning function
On the premise of reduce integral frame structure weight.
Further, on 4 and first fixed plate 1 of liquid cooling plate and the connection mode of the second fixed plate 2, such as Fig. 4, Fig. 5 institute
Show, locating slot is both provided with the opposite surface of the first fixed plate 1 and the second fixed plate 2, and locating slot is used for and liquid cooling plate 4
Both ends are engaged.When in use, by the edges at two ends insertion locating slot of liquid cooling plate 4, contribute to realize that liquid is cold by locating slot
Plate 4 is accurately positioned.Depth wherein on locating slot, is not specifically limited, illustratively, positioning groove depth 3mm, 4mm, 5mm etc..
Also, through hole is provided with 4 end of liquid cooling plate, dowel hole 6 is provided with locating slot, 4 liquid of liquid cooling plate is cold
Through hole on plate 4 is engaged with the dowel hole 6 in locating slot, for through axis pin.So furthermore achieved that liquid cooling plate 4 with
First fixed plate 1, second fixed plate 2 are fixedly connected, and ensure the location accuracy of liquid cooling plate 4.Wherein, in the first fixed plate 1
With in the second fixed plate 2 can also other positions set dowel hole 6, can be according to detector on its quantity and distribution mode
The structure of module is adjusted.
And it can also be set for the through hole through connector in the locating slot of the first fixed plate 1 and the second fixed plate 2,
To ensure the precise positioning to liquid cooling plate 4.Illustratively, connector can be screw, bolt etc..
On the structure of liquid cooling plate 4, referring to Fig. 4：Liquid cooling plate 4 includes substrate 41, and the liquid on substrate 41
Cold pipe 42.Wherein substrate 41 is a kind of aluminum structure tablet, and arc-shaped groove is provided with the surface of substrate 41, copper is welded in groove
Manage the liquid cooling pipe 42 directly curved.Based on the structure of above-mentioned liquid cooling plate 4, use is additionally provided with the locating slot of the first fixed plate 1
In the liquid cooling pipe via 7 through liquid cooling pipe 42, so that the first fixed plate 1 more snugly connects detector module.
In order to save resource, and easy to safeguard, two sets of detector modules can be connected at the same time per framing.Illustratively, join
According to Fig. 3, frame includes the first liquid cooling plate 4A and the second liquid cooling plate 4B.And respectively in the first liquid cooling plate 4A and the second liquid cooling plate 4B
Upper installation detector, forms two groups of detector modules.In this way, a frame is dismantled when being safeguarded can remove two spies
Survey device module.
Two liquid cooling plates 4 are included based on the frame structure that the embodiment of the present invention is provided, to connect two groups of detectors at the same time
The situation of module, referring to Fig. 5, is provided with the first locating slot 1 and the second locating slot 2 in the first fixed plate 1；Referring to Fig. 6,
The 3rd locating slot 3 and the 4th locating slot 4 are provided with two fixed plates 2.Wherein, the first locating slot 1 and the 3rd locating slot 3 are used to divide
The both ends of other the first liquid cooling plate of grafting 4A；Second locating slot 2 and the 4th locating slot 4 are used to distinguish the two of the second liquid cooling plate of grafting 4B
End.
Belong to the locating slot of different liquid cooling plates 4 by being set in the first fixed plate 1 and the second fixed plate 2, realize one group
Frame structure connects two groups of detector modules at the same time.It should be noted that it is all provided with the first locating slot 1 and the second locating slot 2

Degree.And then realize that multiple detector modules surround the polygon of approximate circle.
Wherein, predetermined angle is related to the quantity of detector module in detector rings.Illustratively, a detector rings have
48 detector modules, then predetermined angle for 180 °-(360 ° of ÷ 48)=172.5 °.
It should be noted that on the first fixed plate 1 and the second fixed plate 2, due to only needing to fix the first fixed plate 1
On annular backup pad, the second fixed plate 2 is mainly the effect of auxiliary positioning, therefore the thickness of the second fixed plate 2 is smaller than the
The thickness of one fixed plate 1, to mitigate the weight of single unit system.
Further, referring to Fig. 5, Fig. 6, limiting slot 8, crossbeam are both provided with the first fixed plate 1 and the second fixed plate 2
3 both ends are plugged in the limiting slot 8 of the first fixed plate 1 and the second fixed plate 2 respectively.Realization pair is contributed to by limiting slot 8
Crossbeam 3 is accurately positioned.On the shape of limiting slot 8, illustratively, limiting slot 8 is rectangle, is cut with crossbeam 3 perpendicular to axial
Face shape is adapted, and the depth of limiting slot 8 equally can be 3mm, 4mm or 5mm.Equally set in limiting slot 8 at the same time
There is screw via, for through screw fixed cross beam 3.
In embodiments of the present invention, crossbeam 3 can be hollow-core construction.And first fixed plate 1, the second fixed plate 2, crossbeam 3
And the substrate 41 of liquid cooling plate 4 is prepared using identical material.It can so ensure that different components is respectively provided with identical heat conduction system
Number, avoids, because producing internal stress in temperature change frame structure, influencing its mechanical stability.Illustratively, which uses
It is prepared by the aluminium with thermal conductive resin.
By nuclear medicine detectors frame structure provided in an embodiment of the present invention, can effectively avoid away from ring support
There is radial direction deformation in detector.It is remote using traditional fixed form exemplified by fixing four detectors on each liquid cooling plate 4
The detector deformation of annular backup pad reaches 0.26mm；But after the frame structure provided using the embodiment of the present invention, away from ring
The detector deformation of shape support plate is only 0.058mm, and deflection is the 22.3% of traditional fixed form, greatly improves detector
Positioning accuracy.
