Following improvement can also be carried out to tube body 21：
As shown in Figure 1, Figure 2, Figure 5, end cap 25, tube body 21 are arranged in the nozzle of the one end of tube body 21 far from connecting seat 22
Upper corresponding position is equipped with card slot 26, and one end of wherein card slot 26 is opening-like.
As shown in fig. 6, tube body 21 is eight-sided formation, including eight side walls, respectively the first side wall 211, second sidewall
212, third side wall 213, the 4th side wall 214, the 5th side wall 215, the 6th side wall 216, heptalateral wall 217, the 8th side wall 217；
The first side wall 211, second sidewall 212, third side wall 213, the 4th side wall 214, the 5th side wall 215, the 6th side wall 216, the 7th
Side wall 217, the 8th side wall 217 are symmetrical；Tube body 21 is equipped with several through this on third side wall 213 and heptalateral wall 217
The region of the radiating groove 23 of side pipe wall, the radiating groove 23 opened up on third side wall 213 and heptalateral wall 217 is equal.It does not arrange
It is dissipated except setting in radiating groove 23 or second sidewall 212, the 6th side wall 216 is arranged on the first side wall 211, the 5th side wall 215
Radiating groove 23 is set on heat channel 23 or the 4th side wall 214, the 8th side wall 217, and the present embodiment is preferably in 213 He of third side wall
Radiating groove 23 is set on heptalateral wall 217, the main reason is that, it is easy to process, and heat dissipation area is big.
Radiating groove 23 on tube body 21 can also be improved as follows：
The spacing between two neighboring radiating groove 23 on same side wall is equal, and radiating groove 23 is in the same direction
Into line tilt, the inclined direction of radiating groove 23 is towards connecting seat 22 in the present embodiment, and angle of inclination is between 0-45 degree.According to
Many experiments obtain, are optimal when the angle of inclination of radiating groove 23 is 15 degree, the main reason is that easy to process, heat dissipation area
Greatly.
Between the spacing between two neighboring radiating groove 23 on same side wall is 2-4 times of 23 groove width of radiating groove.
It is obtained according to many experiments, the spacing between two neighboring radiating groove 23 is optimal, master when being 2.5 times of 23 groove width of radiating groove
It wants, the reason is that in same area, more radiating grooves 23 can be arranged, improve thermal diffusivity, while being also avoided that tube body 21 uses
When part between two adjacent radiating grooves 23 occur fractureing or rupture, occur fractureing or be the reason of rupture, two dissipate
23 spacing of heat channel is too small, causes the rigidity of the part between two radiating grooves 23 inadequate.
Between the groove width of radiating groove 23 is 1-3 times of 21 wall thickness of tube body.It is obtained according to many experiments, the groove width of radiating groove 23
It is optimal when being 1.5 times of 21 wall thickness of tube body, if the main reason is that radiating groove 23 opens up excessive, tube body 21 is in radiating groove 23
The rigidity at place is smaller, 21 frangibility of tube body or rupture, and preferably 1.5 times, is to allow radiating groove 23 while ensuring rigidity
Groove width opens up maximum.
Between 21 total length of tube body is 1-4 times of the length in region set by radiating groove 23 on 21 single-sided side walls of tube body.Root
It is obtained according to many experiments, when 21 total length of tube body is 3 times of the length in region set by radiating groove 23 on 21 single-sided side walls of tube body
To be optimal, while ensure that tube body 21 has good thermal diffusivity, the rigidity of tube body 21 when in use is also ensured.
For radiating groove 23 on third side wall 213 and heptalateral wall 217 when opening up, the length of radiating groove 23 is less than third side
The wall wide of wall 213 or heptalateral wall 217 avoids radiating groove 23 from opening up on adjacent side wall, facilitates the processing of radiating groove 23, keeps away
Exempt to influence the rigidity of the junction of two neighboring side wall.
Tube body 21 is made of composite material；The composite material includes that carbon fibre composite, glass fibre are compound
Material or honeycomb sandwich composite.
It is connected with body in order to facilitate connecting seat 22, connecting seat 22 is equipped with connecting hole 24, is being connected on connecting seat 22
It is equipped at hole 24 and makes a concession slot, facilitated and connecting seat 22 is connected with body.
Influence such as the multiple proportion between table 1, the groove width of radiating groove and tube body wall thickness to tube body rigidity and to heat dissipation
The influence of property.
Table 1
| Multiple between the groove width and tube body wall thickness of radiating groove | Tube body rigidity | Tube body thermal diffusivity |
| 0.5 times | It is very high | Difference |
| 1.5 again | It is higher | It is good |
| 2 times | It is high | Very well |
| 4 times | It is low | It is very good |
Such as table 2, the multiple proportion pair that tube body total length is the length in the region of set radiating groove on tube body single-sided side walls
The influence of tube body rigidity and influence to thermal diffusivity.
