Abstract
A temperature control system (100) includes a heating system (1), a cooling system (2) and a control unit (3). The heating system has a heated fluid. The heated fluid is heated by a solar energy for increasing the mold temperature. The cooling system has a cooled fluid. The cooled fluid cools for decreasing the mold temperature. The control unit controls the heating system and the cooling system to be opened or closed.
Claims9
A mold temperature control system, comprising:
- a heating system having a heated fluid, the heated fluid heated by a solar energy heating system and an electrical system for increasing the mold temperature, the heated fluid being driven to circulate under the thermo-syphon heat pipe principle, the electrical system heating the heated fluid to a predetermined temperature which the heated fluid cannot reach if heated by the solar energy alone, wherein the solar heating system comprises a first electromagnetic valve, a first pipe, a first check valve ensuring the heated fluid only flows in a single direction and a collector for absorbing solar energy, the collector being connected with the first electromagnetic valve, the first pipe and the first check valve;
- a cooling system, the cooling system having a cooled fluid for decreasing the mold temperature;
- and
- a control unit, the control unit controlling the activation of the heating system and the cooling system.
