Title: Heat exchanger
Inventor: AOKI AKIRA
IPC: F28D19/04
Filed: 1983-03-03
Abstract: PURPOSE:To improve the heat exchange efficiency of a heat exchanger by a method wherein a plurality of heat pipes are embedded radially in the rotary type heat exchanger, an inner columnar section and an outer cylindrical section are formed within the heat exchanger and passages for a primary air current and a secondary air current are provided lest the air currents should mix with each other whereby the single heat exchanger can be used properly for performing sensible heat exchange operation and total heat exchange operation. CONSTITUTION:Heat pipes 2 are embedded radially in a rotary type heat exchanger 1 and the space within the heat exchanger is divided into inner columnar section 3 and outer cylindrical section 4 through a partition wall 5. The space within the heat exchanger 7 is divided vertically into two parts through a partition plate 8 and the primary air current A flows through the columnar section 3 while the secondary air current B flows through the cylindrical section 4 in the upper part of the heat exchanger 7. In this case, the primary air current and the secondary air current are prevented from mixing with each other by the partition wall 5 and the partition plate 8. The heat exchange between the columnar section 3 and the cylindrical section 4 is performed through the heat pipes and as the heat exchanger rotates, the two air currents flowing through the columnar section and the cylindrical section displace from each other so that the amount of heat exchange and the amount of effective moisture absorption increase due to the lowering of temperature of the heat absorbing surface by the actions of the heat pipes, to thereby improve the overall heat exchange efficiency of the heat exchanger.
