Embodiment approach 1

[0029] refer to Figure 1 ~ Figure 3 , the schematic configuration of the outdoor unit according to Embodiment 1 of the present invention will be described. figure 1 A perspective view showing an outdoor unit. figure 2 yes figure 1 The A-A sectional view of FIG. 1 shows a state in which the front panel 3 of the outdoor unit 1 is removed. image 3 yes figure 2 The shown B-B sectional view of the outdoor unit 1 shows a state where the front panel 3 is attached for convenience of description.

[0030] The outdoor unit 1 is applied to, for example, an air conditioner, and includes a housing 2 constituting an outer outline, a heat exchanger 22 provided in the housing 2 , a compressor 14 , a blower 13 , and an electrical component box 15 .

[0031] The frame body 2 is composed of a front panel 3 constituting the front surface of the frame body 2, a rear panel 8 facing the front surface panel 3 and constituting the back surface of the frame body 2, and a left side when the fram...

Embodiment approach 2

[0069] Next, use Figure 10 , 11The outdoor unit 1 according to Embodiment 2 of the present invention will be described. In contrast to the radiating section 18 of the first embodiment having the louver 20 having the leeward end parallel to the leeward end of the front panel 3 and the plurality of fins 21 , the heat dissipation of the second embodiment The portion 18 is different in that it includes a wind direction plate 30 having a leeward side end that is not parallel to the leeward side ends of the front panel 3 and the plurality of fins 21 .

[0070] Figure 10 A side view showing the heat dissipation unit 18 of Embodiment 2 viewed from the left side panel 4 side of the outdoor unit 1, Figure 11 A bottom view of the radiator 18 according to Embodiment 2 viewed from the bottom panel 6 side of the outdoor unit 1 is shown. Hereinafter, unless otherwise specified, the same reference numerals are assigned to the same configurations as those in Embodiment 1, and descriptio...

Embodiment approach 3

[0089] Next, use Figure 14 The outdoor unit 1 according to Embodiment 3 of the present invention will be described. In contrast to the leeward end 18d of the radiating portion 18 according to Embodiment 1, which is arranged on the leeward side of the virtual plane S, the leeward end 180d of the radiating portion 180 according to Embodiment 3 is arranged on the upwind side of the virtual surface S. The position on the side is different.

[0090] Figure 14 A side view of the radiator 180 according to Embodiment 3 viewed from the left side panel 4 side of the outdoor unit 1 is shown. Hereinafter, unless otherwise specified, the same reference numerals are assigned to the same configurations as those in Embodiment 1, and description thereof will not be repeated.

[0091] Such as Figure 14 As shown, the radiator 180 of the outdoor unit 1 according to Embodiment 3 is formed by a base 190 and a plurality of fins 210 extending at right angles from the base 190 , and the front e...

Abstract

An outdoor unit comprising: a housing 2 having a front panel 3 with an opening 3a formed therein; a blower 13 disposed inside the housing 2; The control board 16 is arranged in the frame body 2 and is equipped with the electrical components 17; the heat dissipation unit 18 emits the heat generated from the electrical components 17; 18 forms a ventilation path 23 for the flow of air generated by the blower 13, and the wind direction plate 20 is not provided on the virtual plane S that covers the entire circumference of the end of the bell mouth 9 and extends parallel to the front panel 3 and the front panel 3. the area between. Thereby, the cooling capability of the heat radiation part 18 can be improved.

Description

technical field [0001] The present invention relates to an outdoor unit and an air conditioner. Background technique [0002] Inside the outdoor unit used in conventional air conditioners, etc., there are provided a control board that controls the operation of compressors, blowers, etc. The heat generated by the components is dissipated. The heat dissipation unit includes a base connected to the control board and a plurality of fins extending from the base. In addition, there is a device in which an air guide is provided on the front end side of a plurality of fins, and a ventilation path surrounded by a base, a plurality of fins, and an air guide is formed, and air is circulated in the ventilation path, thereby The whole heat radiation part is cooled efficiently (for example, patent document 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2009-299907 Contents of the invention [0006] The problem ...
