The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model preferred embodiment proposes a kind of convertible frequency air-conditioner indoor heat exchanger 3, and these indoor heat exchanger 3 place air-conditioner systems comprise compressor 1, outdoor heat exchanger 2, electric expansion valve 4, described indoor heat exchanger 3 and the solenoid operated four-way valve 5 of series connection successively.
In conjunction with Fig. 2 and shown in Figure 3, indoor heat exchanger described in the present embodiment 3 comprises heat exchanger fin 31, the semiconductor cooling device 6 of constant temperature dehumidification while being equipped with for the operation of control air conditioner refrigerating on described heat exchanger fin 31.
Described semiconductor cooling device 6 comprises that semiconductor cooling piece 61 and is used for controlling described semiconductor cooling device 6 work when air conditioner refrigerating moves, controls the out-of-work controller (not shown) of described semiconductor cooling device 6 when air-conditioning heating moves.
The vertical described heat exchanger fin 31 of described semiconductor chilling plate 61 is installed, and be provided with heat-conducting silicone grease 32 between described heat exchanger fin 31 and semiconductor chilling plate 61, be fixedly connected with by described heat-conducting silicone grease 32 between described heat exchanger fin 31 and semiconductor chilling plate 61.When semiconductor cooling device 6 produces heat, first be delivered to heat-conducting silicone grease 32, and then by heat-conducting silicone grease 32, pass to heat exchanger fin 31, thereby guaranteed the conveying of heat.
Particularly, in conjunction with shown in Figure 3, after described semiconductor chilling plate 61 energisings, semiconductor chilling plate 61 has cold junction and the hot junction relative with cold junction, and described hot junction is positioned at heat exchanger fin 31 1 sides.
Heat transfer for the ease of semiconductor chilling plate 61, the present embodiment semiconductor cooling device 6 also is provided with cold junction fin 63 at the cold junction of semiconductor chilling plate 61, simultaneously in the hot junction of semiconductor chilling plate 61, be provided with hot side fin 62, semiconductor chilling plate 61 dispels the heat by hot side fin 62 and cold junction fin 63.
