Energy-saving type air conditioner external unit

Abstract

The invention provides an energy-saving type air conditioner external unit. The energy-saving type air conditioner external unit comprises strip-shaped heat exchange copper tubes which are parallel toone another and are arrayed in the circumferential direction, and the two ends of the strip-shaped heat exchange copper tubes each are provided with an annular heat exchange copper tube communicatingwith all the strip-shaped heat exchange copper tubes; the strip-shaped heat exchange copper tubes and the annular heat exchange copper tubes form a heat exchange cage together; a cylindrical shell isarranged on the periphery of the heat exchange cage, an excitation coil is wound around the inner periphery of the cylindrical outer shell, and the excitation coil is electrified to form a rotary magnetic field which rotates around the axis of the heat exchange cage; a hollow rotating shaft extends on the axis of the heat exchange cage, and the heat exchange cage and the hollow rotating shaft aremutually fixed through at least one fan; the two ends of the hollow rotating shaft are connected to a refrigerant circulating loop in series through sealing rotary joints; and the middle of the hollow rotating shaft is plugged, and by taking the plugging position as a boundary, the two sides of the hollow rotating shaft correspondingly communicate with the annular heat exchange copper tubes on the two sides of the heat exchange cage through connecting tubes. The energy-saving type air conditioner external unit has a good energy-saving effect.

Description

[0001] This application is a divisional application of the invention patent application with the application number 201610487623.5. technical field [0002] The invention relates to the field of heating and ventilation, in particular to an air conditioner external unit. Background technique [0003] The current air conditioner mainly includes an indoor unit and an outdoor unit. The inner unit mainly includes a control module and a fan, which consumes less energy; the outer unit includes a heat pump unit and a fin heat exchanger; The heat exchange efficiency of the fin heat exchanger; for this reason, the fan of the external unit is usually used to continuously supply air to the fin heat exchanger. Even so, the airflow velocity formed by the fan is still very limited. The speed is small, and a fan with high power needs to be used to ensure the heat exchange efficiency of the fin heat exchanger. Therefore, not only the energy consumption is large, but also the working noise is...

Problems solved by technology

[0003] The current air conditioner mainly includes an indoor unit and an outdoor unit. The inner unit mainly includes a control module and a fan, which consumes less energy; the outer unit includes a heat pump unit and a fin heat exchanger; The heat exchange efficiency of the fin heat exchanger; for this reason, the fan of the external unit is usually used to continuously supply air to the fin heat exchanger. Even so, the airflow velocity formed by the fan is still very limited. The speed is low, and a fan with high power needs to be used to ensure the heat exchange efficiency of the fin heat exchanger. Therefore, not only the energy consumption is large, but also the working noise is relatively large.

On the other hand, limited to the special structure of this kind of fin heat exchanger, its permeability is poor. For the external air flow, it is hindered by the driving motor of the fan of the external unit, and it is difficult to pass through the fin heat exchanger, resulting in natural The potential of the airflow cannot be utilized, resulting in wasted energy
