Part, for pumping coolant into cooling structure.Concrete structure for cooling system etc. can use known in the state of the art
Structure, will not be repeated here.
Referring to Figures 1 and 2, a kind of deployment scenarios of cooling structure are shown.In this embodiment, cooling structure includes
Substrate 3 is cooled down, the cooling substrate 3 is preferred to use glass substrate, but is not limited to glass substrate.As shown in Figure 5 and Figure 6, base is cooled down
Plate 3 is located at the lower section of display screen 2 and is fixed in mounting seat 5.Specifically, the feelings of hollow installation portion 51 are included in mounting seat 5
Under condition, hollow installation portion 51 is formed with stage portion in inner side, and the periphery of cooling substrate 3 can be fixed on mounting seat 5 by bolt etc.
Stage portion on, then display screen 2 is fixedly connected with cooling substrate 3, this, which is fixedly connected, to be bonding, it would however also be possible to employ tight
Firmware or other connectors are realized.For example, display screen 2 can be fixedly connected by adhesive with the periphery of cooling substrate 3, make
The runner 3a flowed through for coolant can be formed in centre position by obtaining display screen 2 and cooling substrate 3.Certainly, runner 3a
It is applicable to the flowing of cooling gas.
Reference picture 4 to Fig. 6 concrete structure, display screen 2 include hollow peripheral part and convex portion, cooling substrate 3 can include
Substrate week portion and substrate recess, under the structure, the hollow peripheral part of display screen 2 is fixedly connected with cooling down the substrate week portion of substrate 3,
In the substrate recess of the convex portion insertion cooling substrate 3 of display screen 2 so that runner 3a formation raised part and substrate recess it
Between.More specifically, the groove opened wide towards display screen 2 is formed with the substrate recess of cooling substrate 3, when display screen 2
After convex portion insertion substrate recess, above-mentioned groove is closed in the convex portion of display screen 2, is consequently formed sealed runner 3a.As can be seen that
Heat will be taken away when coolant flows through runner 3a, cooling is realized.
Reference picture 3, shows another deployment scenarios of cooling structure.In the embodiment shown in Fig. 3, cooling structure
Including cooling substrate 3 and sealant 4.Wherein, cooling substrate 3 is equally fixed on the hollow installation portion 51 of mounting seat 5, sealant

Temperature.Compared with the above-mentioned embodiment for not including sealant 4, display screen 2 need not be fixedly connected with cooling substrate 3 and sealant 4,
This provides convenience to change display screen 2.In addition, display screen 2 is fixed without using adhesive, it can avoid making for a long time
Corrosion with middle adhesive to display screen 2, it is therefore prevented that display screen 2 influences the fixed-type quality of resin because of corrosion, extends
The service life of display screen 2.
Preferably, sealant 4 for glass film but can be not limited to glass film, as long as printing opacity and it can not influence to beat
The sealant of print Forming Quality can be used.In the above-described embodiment, sealant 4 be located at display screen 2 and cooling substrate 3 it
Between, specifically it is folded between the convex portion of display screen 2 and the substrate recess for cooling down substrate 3, as needed, sealant 4 can also
Be formed with the projective structure of the groove match on substrate recess etc..In addition, in other embodiment variants, sealant 4
The lower section of cooling substrate 3 can also be fixed on.For example, the runner 3a of cooling substrate 3 is opened downward, make sealant 4 cold
But the lower section of substrate 3 is connected and sealed.Moreover, in another embodiment variant, cooling substrate 3 and sealant 4 can be with
Make integral form etc..It can thus be seen that as long as can provide the cooling structure of coolant radiating should fall into
The protection domain of the disclosure.Wherein, refractive index of the refractive index of coolant preferably with cooling substrate 3 is roughly equal, to avoid drop
The formed precision of low printout.It is to be understood that " roughly equal " herein refers to the refractive index and cooling base of coolant
The refractive index of plate 3 is equal, but in certain tolerance interval coolant refractive index can also less times greater than or slightly less than
Cool down the refractive index of substrate 3.In actual applications, coolant can be from water or oil etc..
Reference picture 4 is provided with the coolant inlet 3b connected with runner 3a on cooling substrate 3 and coolant goes out to Fig. 6
Mouthful 3c, and coolant inlet 3b connects with entry conductor 7, and cooling liquid outlet 3c is connected with delivery channel 8.Concrete structure is,
One end of entry conductor 7 and delivery channel 8 can respectively by pipe joint be connected to cooling substrate 3 on and with coolant inlet 3b
With cooling liquid outlet 3c.The other end of entry conductor 7 and delivery channel 8 can be connected by pipe joint with foregoing cooling system
Connect, so as to realize that cooling system provides coolant into runner 3a, and the coolant of backflow is collected, made in order to circulate
With.In Fig. 4, runner 3a be shaped as from cooling substrate 3 one end extend to cooling substrate 3 the other end it is snakelike.Can be with
Understand, this design can make runner 3a be covered with cooling substrate 3 as much as possible, so as to increase area of dissipation, improve cooling effectiveness.
Certainly, other runners 3a shapes can also be used according to practical application, the disclosure will not enumerate.
According to the advantage of above-mentioned resin pool component, due to the setting of wherein cooling structure, above-mentioned resin pool component is used
Photocuring 3D printer accordingly has 3D printing curing molding efficiency high and the measured advantage of curing molding matter, and due to reducing
The replacement frequency of display screen, therefore reduce the use cost of whole photocuring 3D printer.
The preferred embodiment of the disclosure is described in detail above in association with accompanying drawing, still, the disclosure is not limited to above-mentioned reality
The detail in mode is applied, in the range of the technology design of the disclosure, a variety of letters can be carried out with technical scheme of this disclosure
Monotropic type, these simple variants belong to the protection domain of the disclosure.
It is further to note that each particular technique feature described in above-mentioned embodiment, in not lance
In the case of shield, can be combined by any suitable means, in order to avoid unnecessary repetition, the disclosure to it is various can
The combination of energy no longer separately illustrates.
In addition, can also be combined between a variety of embodiments of the disclosure, as long as it is without prejudice to originally
Disclosed thought, it should equally be considered as disclosure disclosure of that.
