<P>PROBLEM TO BE SOLVED: To provide a heat exchanger achieving a reduction in production costs by reducing the number of manufacturing steps. <P>SOLUTION: This heat exchanger includes: each low pressure refrigerant passage pipe 241 formed by juxtaposing a plurality of low pressure refrigerant passages 2411, exchanging heat between surrounding air and a low pressure refrigerant led to flow into through a low pressure refrigerant inlet header 242 and passed through the low pressure refrigerant passages 2411, and allowing the low pressure refrigerant passed through the low pressure refrigerant passages 2411 to flow out of a low pressure refrigerant outlet header 243; and each high pressure refrigerant passage pipe 244 formed by juxtaposing a plurality of high pressure refrigerant passages 2441, located adjacently to each low pressure refrigerant passage pipe 241, exchanging heat between the surrounding air and a high pressure refrigerant led to flow into through a high pressure refrigerant inlet header 245 and passed through the high pressure refrigerant passages 2441, and allowing the high pressure refrigerant passed through the high pressure refrigerant passages 2441 to flow out of a high pressure refrigerant outlet header 246. The height levels of the low pressure refrigerant passage pipes 241 and high pressure refrigerant passage pipes 244 are displaced from each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
