Background

3D prints and is the topic that very is hot in recent years, through the 3D printer, people can be very convenient make out the article of design, the mould need be done earlier usually in the product preparation in the past, pour and so on process again, the preparation of mould is very expensive, in case the mistake will bring a large amount of losses, and print through 3D and can directly print out the model finished product, and need not carry out the preparation of mould again, can save a large amount of time and energy.

3D prints and melts the material that makes through the heating, spout the outside through the nozzle, it consolidates the shaping to cool down again, however printing some large-scale article, or when printing for a long time, because the volume of printing object itself is too big, and the heat dissipation that can not be fine, and the printing space is direct intercommunication with external space usually not, so lead to the mobility of air relatively poor, lead to when printing model and air carry out the heat exchange, the air of heat absorption can not send out fast through flowing, thereby make the temperature of article unable the reduction late, and the high temperature makes the printing material can't solidify, article deformation appears very easily, lead to printing the product nonconforming.

Traditional cooling means is through means such as fan or water-cooling, cools down to the nozzle, however the inner space of nozzle is smaller, when cooling down to the nozzle, the temperature is hardly controlled, and the cooling range is hour, does not have obvious effect to the cooling of model, and when the cooling range is big, leads to the material to take place the cooling in the nozzle is inside again very easily, leads to the nozzle to block up to when cooling down to the model, in case wind-force too big will make the model blown deformation.
