Abstract
PURPOSE: To raise heat transfer efficiency of the radiator and to simplify the use, by bonding or fusing a flat bag-shaped member here and there along straight or wavy lines, and forming zigzagged water passages at opposite end portion of the bag- shaped member free of bonding or fusing.
CONSTITUTION: The flat bag-shaped member 2 made of film material having a required width, length, thickness and strength is bonded or fused along straight or wavy lines, and zigzagged water passages 6 are formed at opposite end portions of the bag-shaped member 2 free of bonding or fusing. When the temperature of air in the hothouse is lowered, hot water 4 flows downward along the inner surface of film of the heat exchanging bag 2 and passes through zigzagged passages 6 gradually downward to the bottom. While flowing downward through the passages, hot water 4 exchanges heat with air in the hothouse and raises its temperature. Water reached the bottom of bag 2 is discharged to the outside of the hothouse via a drain port 10. Thus, it is enabled to increase heat exchanging area and to prolong heat exchanging time, so that the heat transfer efficiency can be raised even if the temperature difference of water and air in the hothouse is small.
