Description

Technical Field

[0001] The utility model relates to the technical field of mold temperature controllers, in particular to an air-cooled mold temperature controller. Background Art

[0002] The mold temperature controller is a device used to control the mold temperature in the plastic molding industry. The main function of the mold temperature controller is to ensure that the plastic material has good fluidity and melting state during the molding process by controlling the temperature of the mold, thereby ensuring that the plastic products have good quality and dimensional accuracy. In the plastic molding process, the temperature of the mold has an important influence on the molding quality and appearance of the product. If the mold temperature is uneven or the temperature is too high or too low, the quality of the product may be reduced or even unable to be molded. Therefore, the mold temperature controller plays a vital role in the plastic molding industry.

[0003] In certain occasions such as dust-free workshops, there is no cooling water supply, and a certain component needs to be kept at a low temperature, such as 50 degrees. When conventional equipment is not connected to cooling water during operation, due to the heat of the pump body itself and the residual heat after the heating tube is activated, the outlet water temperature exceeds the set temperature after 1 to 2 hours and cannot be reduced.

After the water tank is filled with water, it enters the system pipeline and the system begins to heat up.

The microchannel is made of aluminum and can dissipate heat by exchanging heat with the air. At the same time, the cooler is equipped with a cooling fan, which can enhance air convection and heat exchange effect. When the real-time temperature of the equipment exceeds the set temperature, the fan starts to dissipate heat, further improving the cooling intensity. BRIEF DESCRIPTION OF THE DRAWINGS
