Problems solved by technology
[0006] The purpose of the present invention is to provide an electronic refrigeration heat pipe type 3D printing constant temperature device, which is used to cool down the 3D printing device, so as to solve the problem of poor filament output during the operation of the existing 3D printing device
[0007] When the temperature is unstable during the 3D printing melting process, it is easy to have problems such as wire drawing. The factor that causes the wire drawing problem is the change of the internal temperature of the 3D printing device. If the temperature is too high, the plastic in the nozzle of the printing device will become very viscous, which is not easy flow out of the nozzle

The invention provides an electronic refrigeration heat pipe type 3D printing constant temperature device. The device aims at solving the problems of wire drawing and the like which are easy to occurwhen the temperature is unstable in use of the 3D printing device. The device mainly comprises a temperature sensor, a heat pipe heat exchanger, an electronic refrigerating sheet and a control systemthereof, a radiator and a heat preservation shell, wherein the temperature sensor is used for detecting the change of the internal environment temperature of the 3D printing device box body; when theenvironment temperature is too high, the electronic refrigerating sheet and the control system thereof are triggered, so that refrigerant in the heat pipe heat exchanger flows to the inner bottom of the 3D printing device box body in a liquid state; and the high-temperature environment in the 3D printing device box body enables the liquid refrigerant to evaporate and absorb heat, so that the internal temperature of the 3D printing device box body is reduced, and the problem of unsmooth wire outlet is solved.
