ICE MAKING TYPE HEAT EXCHANGER FOR HEAT ACCUMULATING TANK FOR ROOM COOLING AND HEATING

PURPOSE:To improve heat accumulating efficiency as well as heat exchanging amount by enlarging heat transfer area and preventing leakage by a constitution wherein the constituting unit pipe of the heat exchanger is provided with an upward slope from the outer peripheral pipe of a horizontally arranged scroll-type coil thereof toward the inner peripheral pipe thereof. CONSTITUTION:The heat exchanger is formed by a plurality of constituting unit pipes in which one piece of continuous pipe 5 is wound into scroll shape and is arranged horizontally while the upward slope is provided from the outer peripheral pipe 5-1 toward the inner peripheral pipe 5-2 thereof. The outer peripheral pipe 5-1 is connected to an inlet brine header 3 and the inner peripheral pipe 5-2 is connected to an outlet brine header 3'. Thus, the scrolled continuous pipe is concentrated with a large density and respective unit pipes can be arranged closely with each other, therefore, the heat transfer area may be enlarged and the heat acuumulating efficiency may be improved. Further, leakage can be reduced by decreasing the number of connecting parts and the coils are provided with the slope, therefore, air, entered into the pipes of the heat exchanger may be extracted to the headers and the heat exchanging amount may be increased.
