Title: HEAT EXCHANGER
Abstract:
A heat exchanger having a width of 30 mm or longer to 57 mm or shorter in ventilating direction capable of eliminating such defects that, when the angle of a louver formed in a fin is varied in order to increase a heat exchange efficiency, though a cooling performance is increased when a louver angle is increased, a ventilating resistance is increased, wherein, based on an experiment to obtain a relationship between the louver angle and a factor (capacity of heat exchanger) indicated by the cooling performance/ventilating resistance carried out by varying the louver angle, the maximum value of the factor can be obtained when an inclination angle relative to a louver ventilating direction is approx. 42°, and an appropriate angle to meet the desired requirements (approx. 80% of the maximum value) is within the range of 28° or higher and 55° or lower.
