Description
Caravan air conditioner using mixed flow axial fan assembly Technical Field 2017200100 06 Jan 2017 [0001] The present utility model relates to a caravan air conditioner, and particularly relates to a caravan air conditioner using a mixed flow axial fan.
Background [0002] The caravan air conditioner comprises an outdoor unit, an indoor unit and an air intaking and discharging channel. The outdoor unit comprises an air regulation system consisting of a condenser, an evaporator, a compressor, an evaporative fan and a condensing fan and the like. The indoor unit mainly consists of a panel assembly and an air channel support and the like. The panel assembly is provided with an air intaking and discharging port, and the air intaking and discharging channel is mounted between the air channel support and the outdoor unit. The air in the caravan is sent in the caravan air conditioner via the air intaking and discharging port, and enters into the caravan again after the heat exchange with the evaporator, thereby serving the functions of communicating air and regulating the indoor air temperature.
[0003] The evaporative fan or the condensing fan can be divided into a centrifugal fan and an axial fan, wherein during the operation of the centrifugal fan, an air flow enters into an impeller space from a fan shaft, and then on one hand rotates with the impeller under the driving of the impeller and on the other hand improves the energy under the inertia, the air flow leaves the impeller along the radial direction and works via a generated centrifugal force so as to enable the air flow to be discharged from a peripheral side part of the impeller. The axial fan is that an air flow flows into the impeller from the fan shaft and flows out towards the other end along the fan shaft. A prominent difference between the two is that the centrifugal fan changes the flow direction of a medium in an air pipe, but the axial fan does not change the flow direction of a medium in the air pipe. Compared with the axial fan, the mounting and structure of the centrifugal fan are relatively l complex, the weight is relatively large, and the costs are relatively high. However, the flow directions of air intaking and air discharging of a traditional axial fan are consistent due to the structure of the axial fan itself, which largely limits an application field of the traditional axial fan. 2017200100 06 Jan 2017
