Abstract: A plurality of heat transfer pipes; a first header and a second header to which both ends of each of the heat transfer pipes that are disposed in parallel are fixed, respectively; a plurality of plate shaped fins through which each of the heat transfer pipes is penetrated and that are provided at intervals in a direction in which the heat transfer pipes extend between the first header and the second header; and a fan that circulates an airflow between the plate shaped fins are included. The first header and the second header are formed to be sectioned into multiple rows, the heat transfer pipes are disposed densely in an sectioned area of the first header and the second header, and the heat transfer pipes are disposed sparsely in an area between the sectioned areas of the first header and the second header.

Abstract: A plurality of heat transfer pipes; a first header and a second header to which both ends of each of the heat transfer pipes that are disposed in parallel are fixed, respectively; a plurality of platy fins through which each of the heat transfer pipes is penetrated and that are provided at intervals in a direction in which the heat transfer pipes extend between the first header and the second header; and a fan that circulates an airflow between the platy fins are included. The first header and the second header are formed to be sectioned into multiple rows, the heat transfer pipes are disposed densely in an sectioned area of the first header and the second header, and the heat transfer pipes are disposed sparsely in an area between the sectioned areas of the first header and the second header.

Abstract: A heat exchanger includes a heat transfer tube; a plurality of fins each having ark-shaped contact surfaces configured to be brought into contact with an outer peripheral surface of the heat transfer tube, each of the fins being attached from the outside in a radial direction of the heat transfer tube; an adhesive that bonds the outer peripheral surface of the heat transfer tube and the contact surface of each of the fins; and a position regulation portion which is provided between the fins adjacent to each other in the tube axis direction and regulates a position in the tube axis direction of each of the fins.
