Outdoor side heat exchange structure of air conditioner all-in-one machine

Abstract

The invention relates to an outdoor side heat exchange structure of an air conditioner all-in-one machine. The outdoor side heat exchange structure of the air conditioner all-in-one machine comprises a shell, a condenser and a fan, wherein the condenser and the fan are arranged in the shell; and the shell is provided with an air inlet and an air outlet. The outdoor side heat exchange structure of the air conditioner all-in-one machine is characterized in that the fan is positioned between the condenser and the air outlet; the condenser surrounds the fan; the fan rotates to generate negative pressure to suck air outside the shell into the shell and drive the air to flow through the condenser and then to be discharged out of the shell; the air enters the shell through the air inlet; and after the air exchanges heat with the condenser, the air is discharged out of the shell through the air outlet. According to the outdoor side heat exchange structure of the air conditioner all-in-one machine provided by the invention, when the fan sucks air, the flowing state of air entering the shell is mainly a laminar flow state, the air flows through all the positions of the condenser from multiple directions and then is exhausted from the air outlet, the air volumes and the air speeds of all the positions of the condenser are the same, and air supply is uniform, so that the heat exchange effect of the condenser is good, and the heat exchange efficiency of the condenser is high.

Description

technical field [0001] The invention relates to the technical field of an air conditioner integrated machine, in particular to an outdoor heat exchange structure of an air conditioner integrated machine. Background technique [0002] The outer heat exchange structure of the air conditioner all-in-one used in the market is a blowing heat exchange form. The all-in-one air conditioner adopts this method to output air. The airflow near the fan outlet is mainly turbulent flow, and the local heat exchange is strong. It is suitable for the situation where the heating components are relatively concentrated. At this time, the main air outlet of the fan must be aligned with the heat-generating part; Due to the directionality of the blowing, the air supply to the entire condenser will be uneven, and there is a partial backflow and low-speed area near the fan HUB and between the parallel fans, and the heat exchange is poor. It is necessary to keep the fan and the condenser Enough dista...

The all-in-one air conditioner adopts this method to output air. The airflow near the fan outlet is mainly turbulent flow, and the local heat exchange is strong. It is suitable for the situation where the heating components are relatively concentrated. At this time, the main air outlet of the fan must be aligned with the heat-generating part; Due to the directionality of the blowing, the air supply to the entire condenser will be uneven, and there is a partial backflow and low-speed area near the fan HUB and between the parallel fans, and the heat exchange is poor. It is necessary to keep the fan and the condenser Sufficient distance to make the air supply uniform. Due to the limited space of the machine, it cannot meet the space requirements, resulting in low heat transfer efficiency and uneven heat transfer of the condenser, so the capacity and energy efficiency are not high.
