PURPOSE:To contrive to improve the quality of a heat exchanger, by a method wherein the deviation of air flow which flows between fins is removed, and fins are used effectively. CONSTITUTION:Refrigeration medium which enters to the heat exchanger from an entrance connecting pipe 3 as shown by an arrow mark 7, flows deviating to the downstream side against the direction 6 of heat source fluid in heat transfer pipes 1a and 1b. Refrigeration medium out of the heat transfer pipe 1b is collected in a U-type pipe 11, and enters the next heat transfer pipe 1c in the direction against the flow direction 6 of heat source fluid changing the flow direction from the entrance connecting pipe 3. As this result, the deviation of refrigeration medium flow is positioned alternately to the upstream and downstream towards the exit from the entrance of the heat transfer pipe against the flow direction 6 of heat source fluid, and fins 2 which are connected to the upper parts and down parts of heat transfer pipes can be used effectively. |
