Problems solved by technology

Compared with axial flow fans, centrifugal fans have more complex installation and structure, larger weight and higher cost
However, the traditional axial flow fan has a relatively limited application field due to its own structure that determines the flow direction of the air inlet and outlet air to be consistent.

Embodiment 1

[0026] Embodiment 1: as figure 1 , figure 2 and image 3 As shown, the RV air conditioner using a mixed-flow axial fan includes an air-conditioning main body 1. The air-conditioning main body 1 has a heat exchange system, a central air inlet channel 2, and a peripheral air outlet channel 3. The heat exchange system includes annularly distributed evaporators. Component 4 and a mixed-flow axial fan 5 located in the evaporator component 4. The mixed-flow axial fan 5 includes an axial fan 6 and a skeleton-type wind circle 7. The axial-flow fan 6 is installed in the skeleton-type wind circle 7. The skeleton-type The wind ring 7 includes a drainage pressurization area 71 and an airflow diffusion area 72 for air outlet. The airflow diffusion area 72 includes a circumferential air outlet area 721 and an axial air outlet area 722 . The axial flow fan 5 is located in the annularly distributed evaporator assembly 4, the space inside the air conditioner is fully utilized, and it is ben...

Abstract

The invention discloses a touring car air conditioner using a mixed-flow type axial fan. The touring car air conditioner comprises an air conditioner body. A heat exchange system, a central air inlet channel and a peripheral side air outlet channel are arranged in the air conditioner body. The heat exchange system comprises an annularly-distributed evaporator assembly and the mixed-flow type axial fan located in the evaporator assembly. The mixed-flow type axial fan comprises an axial fan and a framework type air ring, wherein the axial fan is installed in the framework type air ring, the framework type air ring comprises a flow guide pressurizing area and an air flow diffusion area used for discharging air, and the air flow diffusion area comprises a peripheral air outlet area and an axial air outlet area. The air ring is of a framework supporting structure, so that the strength requirement for installation of the axial fan is met, the direction of air flow blown out of the axial fan is changed through the lower flow guide pressurizing structure and the upper diffusion structure of the air ring, the axial fan can discharge air in the perpendicular direction and can also discharge air in the peripheral direction, and thus the mixed-flow air blowing effect is formed.

Description

technical field [0001] The invention relates to an air conditioner for a caravan, in particular to an air conditioner for a caravan using a mixed-flow axial flow fan. Background technique [0002] The RV air conditioner includes an outdoor unit, an indoor unit and air inlet and outlet channels. The outdoor unit includes an air conditioning system consisting of a condenser, an evaporator, a compressor, an evaporation fan, and a condensation fan. The indoor unit is mainly composed of panel components and air duct brackets. An air inlet and outlet are arranged on the panel assembly, and the air inlet and outlet channels are installed between the air channel support and the outdoor unit. The air in the car is sent into the car air conditioner through the air inlet and outlet channels, and then enters the car again after exchanging heat with the evaporator, so as to play the role of air circulation and adjust the indoor air temperature. [0003] Evaporating fans or condensing ...
