The utility model discloses technical scheme is through setting up air guide 150 in air conditioning equipment 100, and in the heat exchange process of heat exchanger 140, air guide 150 will be by the air current direction heat exchanger 140 that air intake 115 got into, air current tissue in air conditioning equipment 100 has been optimized to air guide 150 from this, the unordered flow state that gets into the air current in air conditioning equipment 100 in the past and need flow through the heating part such as air conditioning equipment's 100 compressor 170 of air conditioning equipment has been changed, make the air current that has the air intake 115 to get into can not receive other heating element's in air conditioning equipment 100 influence and all flow through heat exchanger 140 as far as possible and carry out discharge after the heat exchange, make air conditioning equipment 100's heat exchange efficiency obtain promoting, the wholeness can be showing and promote.

The wind guide 150 of the present application mainly guides the airflow entering from the air inlet 115 to the heat exchanger 140 for sufficient heat exchange and then discharges the airflow, and the important function of the wind guide 150 is to guide the airflow at the portion near the air inlet side of the heat exchanger 140, so as to prevent the airflow from flowing through the gap between the heat exchanger 140 and the outer shell 111 and directly entering the wind wheel 180 without exchanging heat with the heat exchanger 140 to be discharged, so the wind guide 150 can have various structural forms, for example, the wind guide 150 can be in a horn shape or a tubular shape enclosing a circle to make the airflow flow through the heat exchanger 140 as much as possible. Therefore, the periphery of the air guide 150 facing one end of the heat exchanger 140 is arranged around the edge of the heat exchanger 140, wherein the periphery of the air guide 150 facing one end of the heat exchanger 140 is arranged around the edge of the heat exchanger 140, the periphery of the air guide 150 can be located at the outer edge of the heat exchanger 140 to surround, or the periphery of the air guide 150 can fall on the edge of the heat exchanger 140 to surround, and the purpose is to limit the airflow in the heat exchange area of the heat exchanger 140, so that the airflow is prevented from flowing through the gap between the heat exchanger 140 and the outer shell 111, and the heat exchange efficiency is further improved.

Furthermore, because there are many components which are easy to generate heat, such as the compressor 170 (see fig. 5), the capacitor, and the circuit board, inside the mobile air conditioning device, if the airflow entering from the air inlet 115 flows through the above devices, the heat of the above devices is absorbed and then heat exchange is performed, which will affect the heat exchange efficiency, for this reason, in order to further improve the heat exchange efficiency, on the basis of the above structural characteristics, the air guide 150 of the air conditioning device 100 of the present application may further form an air guide cavity 110b (see fig. 3) by enclosing the air guide 150 with the casing 110, the air guide cavity 110b is formed as the front section of the air exhaust channel 110a, and the air guide cavity 110b communicates the air inlet 115 and the air inlet side of the heat exchanger 140.
