PURPOSE: The temperature control device simplifies the structure of a stock tank by cooling the temperature of cool water in a cooling tank with a simple cooling coil and making the material supplied to the stock tank exchange heat with a heat exchanger. CONSTITUTION: A temperature control device comprises a hot water tank(16), a cooling tank(18), a heating device(17), a cooling coil(180), a hot water circulating pump(22), a cool water circulating pump(24). The heating device(17) heats hot water in the hot water tank(16) to a certain temperature. The cooling coil(180) is a cooling device cool down cool water in the cooling tank(18) to a certain temperature and circulates cool water supplied from outside in the cooling tank(18). The hot and the cool water circulating pumps(22, 24) are installed between work tanks(14A, 14B) and the hot water tank(16) and between the work tanks(14A, 14B) and the cooling tank(18) to selectively supply hot water and cool water in the hot water tank(16) and the cool water tank(18) to the work tanks(14A, 14B) respectively. Material supply pipelines(8A, 8B) connected with stock tanks(12A, 12B) exchanges heat with heat exchangers(21A, 21B) connected to the outlets of pumps(22, 24) to adjust the temperature of the stock tanks(12A, 12B).
