Below in conjunction with the embodiment described in Fig. 1-4, biometric print machine temperature control system of the present utility model is described further.In this embodiment, the biometric print machine that biometric print machine temperature control system is applied, its biometric print containers 4 includes the first containers 41 and the second containers 42, first containers 41 and the second containers 42 are connected on the installing plate 6 of biometric print machine by thermal insulation board 7, the nozzle 5 of biometric print machine is directly connected in the exit of the first containers 4, and the outlet of the second containers 42 is then connected with nozzle 5 by auxiliary material runner 421.First containers 41 can as being used for containing the main material container of main material (also known as biological prepared Chinese ink), second containers 42 can as being used for containing the auxiliary material container of auxiliary material (such as hydrogel), such as auxiliary material may be used for main material is formed parcel, damages to avoid raw main material to be subject to the destruction of mechanical force in print procedure.Certain main material and auxiliary material can also otherwise be combined, for instance mixing etc..
As Figure 1-4, in this embodiment, biometric print machine temperature control system includes two independent container temperature control systems 1, a set of nozzle temperature control system 2 and a set of runner temperature control system 3, wherein, one container temperature control system 1 is for carrying out temperature control to the first containers 41, another container temperature control system 1 is then for carrying out temperature control to the second containers 42, nozzle temperature control system 2 is for carrying out temperature control to nozzle 5, and runner temperature control system 3 is then for carrying out temperature control to auxiliary material runner 421.Respectively the first containers 41 and the second containers 42 are carried out temperature control by arranging two independent container temperature control systems, it is possible to meet main material and the auxiliary material different demands to temperature of different qualities.
Due in this embodiment, the structure of two sleeve containes temperature control systems 1 is essentially identical, therefore, next only for the container temperature control system 1 being wherein located at the second containers 42 place, container temperature control system 1 is illustrated.
As shown in Figure 2 and Figure 4, in this embodiment, container temperature control system 1 include heat conducting sleeve 11, as the semiconductor refrigeration system of heat-exchange device, the first soaking plate 14 and the second soaking plate 15.Wherein, semiconductor refrigeration system includes semiconductor cooling device 12 and heat abstractor 13, heat conducting sleeve 11 is set in the periphery of the second containers 42, first side of semiconductor cooling device 12 is connected with heat conducting sleeve 14 by the first soaking plate 14, and the second side of semiconductor cooling device 12 is connected with heat abstractor 13 by the second soaking plate 15.
Semiconductor refrigeration system both can serve as thermal source, can serve as again low-temperature receiver.Theoretical according to semiconductor refrigerating, apply a DC voltage in the semiconductor chilling plate both sides of semiconductor refrigeration system and will produce a DC current, this can make the heating of semiconductor chilling plate side and opposite side refrigeration.Generally the side of heating is called " hot side ", and the side freezed is called " huyashi-chuuka (cold chinese-style noodles) ".Semiconductor chilling plate has control end, after controlling end transmission instruction, the polarity of voltage of semiconductor chilling plate both sides can be exchanged, make reverse direction current flow, thus realizing the huyashi-chuuka (cold chinese-style noodles) of semiconductor chilling plate and the mutual conversion of hot side, namely it is capable of the mutual conversion of semiconductor refrigeration system refrigeration and heat-production functions, except cold and hot surface exchanges, it is also possible to realize accurate temperature according to demand and control (precision 0.01 degree).Visible, adopt semiconductor refrigeration system as heat-exchange device of the present utility model, it is possible to easily and effectively to realize the heating to the second containers 42 or refrigeration, to meet the different temperatures demand of various biometric print material.
In this embodiment, container temperature control system 1 can arrange vessel temp detection control apparatus, and switched between heating work state and refrigeration work state by this vessel temp detection control apparatus control semiconductor refrigeration system.As shown in Figure 4, in this embodiment, vessel temp detection control apparatus includes control system (not shown) and the first temperature sensor 18 being arranged on heat conducting sleeve 11, this first temperature sensor 18 is for detecting the temperature of heat conducting sleeve 11 and being transferred to control system, owing to the temperature of heat conducting sleeve 11 is consistent with the temperature of the second corresponding containers 42, therefore, first temperature sensor 18 can detect the temperature of the second containers 42 and be transferred to control system, control system then passes through to compare the duty of the difference control semiconductor refrigeration system of the temperature (generally presetting in the controls) required for the temperature of the second containers 42 and auxiliary material, thus realizing the closed loop control to the second containers 42 temperature, improve accuracy of temperature control.After the first temperature sensor 18 detects that the temperature of the first containers 41 and the second containers 42 reaches the temperature required for biomaterial, it is possible to control to add corresponding material in the first containers 41 and the second containers 42 respectively.
It is arranged on the first soaking plate 14 of semiconductor cooling device 12 first side, uniformly transferring of heat can be realized by the mode that its internal gas-liquid two-phase is changed mutually, so that the heat between semiconductor cooling device 12 and the second containers 42 transmits uniform high-efficiency more, and then effectively prevent because semiconductor cooling device 12 cannot cover the phenomenon of the heat transfer inequality that heat conducting sleeve 11 causes comprehensively, and owing to semiconductor chilling plate need not be covered on whole heat conducting sleeve 11 so that structural design and space layout are also simpler compact；nullThe heat transmission that the second soaking plate 15 being arranged on semiconductor cooling device 12 second side then enables between semiconductor cooling device 12 and environment is more uniform，Reduce the temperature difference of semiconductor cooling device 12 first side and the second side，Owing to there is reverse heat transfer process between huyashi-chuuka (cold chinese-style noodles) and the hot side of semiconductor cooling device，And the temperature difference of cold and hot surface is more big，This reverse heat transfer process is more obvious，And it is equal with the heat that reverse heat is transmitted once the heat that just thermotropism transmits，The temperature of huyashi-chuuka (cold chinese-style noodles) and hot side just no longer changes，Affect refrigeration or the heat effect of semiconductor cooling device 12，Therefore，The temperature difference of semiconductor cooling device 12 first side and the second side is reduced by arranging the second soaking plate 15，Reverse heat transfer effect can be weakened，Give full play to refrigeration or the heat effect of semiconductor cooling device 12.
