In these embodiments, the effective length of the evaporator 3 is the length that the evaporator 3 can actually use for the intake air, that is, the length of the windward side of the evaporator, so the effective length is not equal to the actual length of the evaporator 3, and the effective length L2 of the evaporator 3 is limited to be 500mm-1000mm, so that the length that the evaporator 3 can use for the intake air is relatively moderate, which can ensure the intake air volume of the evaporator 3 and the overall heat exchange efficiency of the product.
It should be noted that the effective length and the effective width of the evaporator 3 and the air intake grille 2 are both the length and the width of the portion that can actually supply air during operation, and the length and the width of the other portion that can only be installed or the gap between the other portion and the surrounding area is too small to supply air are not within the effective length and the effective width.
In any of the above embodiments, preferably, the effective length a of the air intake grille 2 is greater than or equal to 550mm and less than or equal to 690 mm; and/or the effective width b of the air inlet grille 2 is larger than or equal to 140mm and smaller than or equal to 165 mm; and/or the effective width L1 of the evaporator 3 is greater than or equal to 250mm and less than or equal to 350 mm; and/or the effective length L2 of the evaporator 3 is equal to or greater than 550mm and equal to or less than 690 mm.
In these embodiments, the effective length a of the air intake grille 2 may be further limited within a range of 550mm or more and 690mm or less, the effective width b of the air intake grille 2 may be further limited within a range of 140mm or more and 165mm or less, the effective width L1 of the evaporator 3 may be further limited within a range of 250mm or more and 350mm or less, and the effective length L2 of the evaporator 3 may be further limited within a range of 550mm or more and 690mm or less, so that the effective length and the effective width of the air intake grille 2 and the effective length and the effective width of the evaporator 3 may be further precisely limited, and the windward area of the evaporator 3 may be more matched with the windward area of the air intake grille 2, thereby further reducing windage resistance and improving heat exchange efficiency.
In any of the above embodiments, preferably, the air inlet grille 2, the evaporator 3 and the inner wall of the housing 1 enclose an air inlet channel communicated with the air inlet hole, and the air inlet channel includes a first section of air channel with a width greater than or equal to 6mm and a second section of air channel with a width less than 6 mm; wherein, the effective length a of air inlet grille 2 is the length of the position that air inlet grille 2 corresponds first section wind channel setting, and the effective width b of air inlet grille 2 is the width of the position that air inlet grille 2 corresponds first section wind channel setting, and effective width L1 of evaporimeter 3 is the width of the position that evaporimeter 3 corresponds first section wind channel setting, and effective length L2 of evaporimeter 3 is the length of the position that evaporimeter 3 corresponds first section wind channel setting.
In these embodiments, when the width of the air inlet channel is less than 6mm, the wind is hardly circulated basically, so the air duct with the width less than 6mm cannot realize real air inlet, therefore, we divide the air duct into two parts by the width of the air duct, specifically, the part with the width less than 6mm is called as a second section air duct, where the second section air duct has a larger width, so that the air inlet can be realized, and it belongs to an effective air duct (i.e. an air duct capable of air inlet). The part of the air duct with the width of more than or equal to 6mm is called a first section of air duct, and the first section of air duct cannot really realize air inlet due to the narrow width, and belongs to an invalid air duct (namely, the air duct cannot really realize air inlet). The effective length and the effective width of the air-inlet grille 2 and the evaporator 3 in the present application are the length and the width of the part of the air-inlet grille 2 and the evaporator 3 which can be used for forming the first section of the air channel, and the length and the width of the part of the air-inlet grille 2 and the evaporator 3 which are used for enclosing the second section of the air channel are not calculated in the range of the effective length and the effective width. This kind of structure has rationally injectd effective width and the effective length of evaporimeter 3 and air-inlet grille 2 to can make the effective windward area of evaporimeter 3 and the effective air inlet area of air-inlet grille 2 match more.

Wherein, the air inlet end of the fan 4 is the end of the wind entering the fan 4. The fan 4 is not arranged between the air inlet grille 2 and the evaporator 3, but is arranged behind the evaporator 3 approximately, so that the fan 4 can generate suction force during working, wind energy entering the air inlet grille 2 can directly and quickly enter the evaporator 3, the wind speed can be increased, the air quantity can be increased, the heat exchange effect can be increased, and the heating or refrigerating capacity can be improved.
