Heat exchanger of duct type air conditioner and duct type air conditioner

The utility model discloses a duct type air conditioner heat exchanger and a duct type air conditioner, the heat exchanger comprises a plurality of heat exchange fins and a plurality of heat exchange tubes, the plurality of heat exchange fins are arranged at intervals along a first direction, and an air flowing space is arranged between adjacent heat exchange fins; the heat exchanger comprises a first part and a second part, the first part comprises an inclined part, the inclined part obliquely extends towards the leeward side from top to bottom, and the second part obliquely extends towards the windward side from top to bottom; the inclination angle of the inclined part is A, the inclination angle of the second part is B. The heat exchanger meets the condition that A is larger than B. Therefore, the inclination angle A of the inclination part is larger than the inclination angle B of the second part, so that the opening area of the opening, jointly defined by the first part and the second part, of the heat exchanger is large, it is guaranteed that the flow speed of airflow capable of flowing into the heat exchanger is large, and the heat exchange efficiency of the airflow and the heat exchanger is improved.
