Circulating explosion-proof electric heater

For customers who require both heating and cooling, with high cooling requirements, temperatures below room temperature, and a large number of molds, if they are made into a cold and hot integrated machine, it not only requires a large number of units but also has a high cost. In order to save costs and meet customer process requirements well, multiple mold temperature machines can be used to heat them, Cooling is achieved by using a slightly larger circulating explosion-proof electric heater and a water tank for energy storage to simultaneously cool several molds; The working principle is as follows:
The circulating explosion-proof electric heater heating system is an electric heating mold temperature machine that can automatically control the temperature of the mold. The heating equipment uses electricity as the heat source and heat transfer oil as the heat carrier. It utilizes a high-temperature circulating oil pump to forcibly circulate and transport the heat energy to the mold; Then return to the direct current heating equipment that continues to heat again, so as to achieve continuous increase in heat and increase the mold temperature, meeting the process requirements of constant heating temperature;
The cooling system uses an energy storage water tank for energy storage, which is cooled by a compressor with water as the cooling carrier. A water circulation pump is used to circulate the cooling water to the internal heat exchanger of the mold temperature machine for heat exchange. The heat exchanger indirectly cools the heat transfer oil of the circulating explosion-proof electric heater, and then cools the mold through the cooled heat transfer oil circulation. The cooling water then returns to the energy storage water tank for re cooling, achieving continuous cooling, Reduce the mold temperature to meet the process requirements of constant cooling temperature.
In addition, when the mold needs to remove heat without cooling, the circulating explosion-proof electric heater circulates with the energy storage tank. During the mold heating process, the water in the energy storage tank is cooled and stored in the energy storage tank. When cooling is needed, the valve opens to enter and exit the internal heat exchanger of the circulating explosion-proof electric heater for indirect cooling, achieving the purpose of cooling.
