Embodiment Construction

[0024] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] figure 2 is a schematic diagram showing a heat exchanger according to one embodiment of the present invention. As shown in the figure, the heat exchanger includes: a plurality of rows of refrigerant tubes 2 and 4 through which refrigerant flows; and a plurality of fins 10 connecting the front row of refrigerant tubes 2 and the rear row of refrigerant tubes 4 . In addition, a plurality of fins 10 are coupled to the refrigerant tubes 2 and 4 at a predetermined distance.

[0026] In addition, the refrigerant tubes 2 and 4 are arranged vertically to the flow direction of the air A in the longitudinal direction, and the fins 10 are arranged to extend parallel to the flow direction of the air A. As shown in FIG. The refrigerant tubes 2 and 4 also include a front row of refrigerant tubes 2 located in the front and a rear row of refrigerant tubes 4 loc...

Abstract

A heat exchanger including a plurality of first refrigerant tubes, and a plurality of second refrigerant tubes separated from the plurality of first refrigerant tubes in an air flow direction. Further, a diameter of a respective refrigerant tube of the plurality of first refrigerant tubes is smaller than a diameter of a respective refrigerant tube of the plurality of second refrigerant tubes.

Description

technical field [0001] The present invention relates to a heat exchanger for exchanging heat between refrigerant and air, and a refrigeration cycle device having the heat exchanger; especially to such a heat exchanger, wherein forward and backward along the direction of air flow A plurality of refrigerant tubes through which the refrigerant flows is provided, and relates to a refrigeration cycle device with the heat exchanger. Background technique [0002] A refrigeration cycle device that uses a refrigeration cycle to cool / heat a space generally includes a compressor, a condenser, an expander, and an evaporator. Also, the heat exchanger including the condenser and the evaporator has a refrigerant passage through which the refrigerant flows. [0003] Various types of heat exchangers exist. For example, in a fin-tube type heat exchanger, fins for increasing a heat transfer area are coupled to refrigerant tubes through which refrigerant flows. In more detail, figure 1 It i...
