Abstract
Problem to be Solved To provide a heat exchanger that can increase the performance by setting an optimal number of tube groups in a configuration where each of the tube groups is provided with headers. Solution The number of arrays of tube groups of a core sectionis set to three rows. The number N of heating medium flow holesper tube is set for each width dimension Tw of tubes, and the tubesare formed such that the width dimension Tw of the tubes and a flow channel cross-sectional area S satisfy a relationship of S1≤S≤S2. Therefore, the number of arrays of the tube groups in the core sectioncan be set to an optimal number of arrays for improving the endothermic capacity and reducing the weight, and sufficient refrigerant flow rate and pressure resistance can be secured. As a result, even when there is a restriction on the size of the entire heat exchanger, a light high-performance heat exchanger can be configured. This is significantly advantageous when the heat exchanger is used as an evaporator of a vehicle air conditioning apparatus for which a reduction in the weight of the components and an increase in the performance are demanded.
