Embodiment approach 1

[0045] figure 1 It is a figure which shows the schematic cross section of the air conditioner which concerns on Embodiment 1 of this invention.

[0046] In the air conditioner of this embodiment, although not shown, the refrigerant circulates in the order of the compressor, the four-way valve, the heat source side heat exchanger, the expansion valve, the use side heat exchanger, the four-way valve, and the compressor. The heat source side heat exchanger functions as a condenser, and the utilization side heat exchanger functions as an evaporator, thereby performing cooling operation. In addition, by switching the four-way valve, in this air conditioner, the refrigerant circulates in the order of the compressor, the four-way valve, the use-side heat exchanger, the expansion valve, the heat source-side heat exchanger, the four-way valve, and the compressor. The heat exchanger on the utilization side functions as a condenser, and the heat exchanger on the heat source side functi...

Embodiment approach 2

[0084] Figure 11 The protrusion of the plate fin of Embodiment 2 is shown. In this embodiment, the protrusions 18 (18a, 18aa, 18ab, 18b) provided on the plate fin 11 are as follows: Figure 11 As shown, it is formed by cutting and forming along the refrigerant flow path 16 , and the cutting and forming end edge E is configured to face the flow direction W of the air flowing between the stacks of the plate fins 11 .

[0085] Thereby, in the protrusion part 18 (18a, 18aa, 18ab, 18b), it is possible to make the space|interval between plate-fin laminations constant, and to make it easy to install on the downstream side of the protrusion part 18 (18a, 18aa, 18ab, 18b). The resulting dead water area is extremely small and acts as a leading edge effect in the section of the cut-away edge E. Furthermore, since the cut-and-formed end edge E portion is opposed to the flow direction W of the air, the flow resistance to the air becomes small. Therefore, an increase in flow path resist...

Abstract

An air conditioner according to the present invention is provided with: a heat exchanger configured by stacking plate fins; a blower that blows air to the heat exchanger; and a water receiving tray disposed below the heat exchanger in the vertical direction. A gap is formed between neighboring plate fins by protruding parts disposed on the plate fins and composed of a plurality of protrusions. Theheat exchanger is provided inclined. The protruding parts have a plurality of lower protrusions that are disposed further inside than lower end edges of the plate fins.

Description

technical field [0001] The present invention relates to an air conditioner, in particular to an air conditioner capable of suppressing enlargement of a drain pan for condensed water generated when a plate-fin laminated heat exchanger is used, and performance degradation of the entire device. Background technique [0002] In general, in an air conditioner, cooling or heating is performed by circulating refrigerant compressed by a compressor through heat exchangers such as a condenser and an evaporator to exchange heat with air. Here, the heat exchanger is installed obliquely in the air passage in the main body, and a drain pan for receiving condensed water generated in the heat exchanger during cooling etc. is provided (for example, refer to Patent Document 1). [0003] Figure 12 The air conditioner described in patent document 1 is shown. In this conventional air conditioner, an air outlet 101 is provided above a main body 100, and an air inlet 102 is provided on the lower...
