Problems solved by technology

[0002] The current air-conditioning outdoor unit mainly adopts finned heat exchangers, which include heat-dissipating fins and heat-exchanging copper tubes fixed with the heat-dissipating fins; The fins continuously supply air; because the overall space composed of cooling fins and heat-exchanging copper tubes is large, and the ventilation direction is single, it is necessary to use a large-power drive motor and heat-exchanging fan to ensure good heat-exchange performance; this It not only makes the outdoor unit bulky and inconvenient to install, but also often produces a lot of noise, which affects the rest environment

Embodiment 1

[0019] exist figure 1 In the first embodiment shown, the heat exchanger of the simple air-conditioning external unit includes a heat-exchanging copper tube 1; a rotating tube 2 is connected in series in the heat-exchanging copper tube 1, and the two ends of the rotating tube 2 are rotated by sealing. The joint 21 is serially connected to the heat exchange copper tube 1 . figure 1 Only one rotating tube 2 is shown in the figure, in fact, the rotating tubes 2 can be equidistantly distributed along the heat-exchanging copper tube 1; the inner wall of the rotating tube 3 is fixed with an inner impeller whose rotation plane is perpendicular to the axis of the heat-exchanging copper tube ( figure 1 not shown); the outer wall of the rotating tube 3 is fixed with an outer rotating wheel 3; the inner impeller, driven by the fluid in the heat exchange copper tube 1, drives the rotating tube 3 to rotate and synchronizes the outer rotating wheel 3 Rotation; the outer rotating wheel 3 is ...

Embodiment 2

[0022] exist figure 2 In the second embodiment shown, the heat exchanger of the simple air conditioner external unit includes a heat exchange copper tube 1; the heat exchange copper tube 1 is connected in series with an inner impeller 4 whose rotation plane is orthogonal to the axis of the heat exchange copper tube; The outside of the heat exchange copper tube 1 is provided with an outer rotating wheel 3 surrounding the heat exchange copper tube 1 and corresponding to the inner impeller 4. The outer rotating wheel 3 is the same as the first embodiment. Axial air flow is formed on the surface of tube 1.

[0023] The inner impeller 4 and the outer rotating wheel 3 are coupled to each other through a coupling mechanism, so that the inner impeller 4 can drive the outer rotating wheel 3 to rotate.

[0024] In the second embodiment, the coupling mechanism includes an inner bearing 5 arranged inside the heat exchange copper pipe 1, an outer bearing 6 arranged outside the heat excha...

Embodiment 3

[0028] for image 3 The third embodiment shown is different from the second embodiment in that: the coupling mechanism includes a fixed joint 7 connected in series in the heat exchange copper tube 1 and an inner bearing 5 arranged inside the fixed joint 7 , the outer bearing 6 that is arranged on the outside of the fixed joint 7 and surrounds the inner bearing 5; the inside of the fixed joint 7 forms an annular cavity that arches to the outside of the heat exchange copper tube 1, and the inner bearing 5 is located in the annular cavity In the cavity, there is a gap between the inner ring of the inner bearing 5 and the two end walls of the annular cavity, so that the inner ring of the inner bearing 5 can rotate freely; the inner impeller 4 is fixed on the inner ring of the inner bearing 5 , the outer rotating wheel 3 is fixed on the outer ring of the outer bearing 6 . According to the third embodiment, since there is no rotary joint, relatively good sealing performance can be ...

Abstract

The invention provides a simple heat exchanger for an outdoor unit of an air conditioner. The simple heat exchanger comprises a heat exchanging copper pipe, wherein an inner impeller of which a rotating plane is orthogonal to an axis of the heat exchanging copper pipe is connected in series with the heat exchanging copper pipe; an outer rotating wheel, which is arranged around the heat exchanging copper pipe and corresponds to the inner impeller, is arranged at the outer part of the heat exchanging copper pipe; when rotating, the outer rotating wheel can generate air flow close to the heat exchanging copper pipe; the inner impeller and the outer rotating wheel are coupled through a coupling mechanism, so that the inner impeller can drive the outer rotating wheel to rotate. The heat exchanger is free of a heat exchange fan and cooling fins, so that the size is simple and small, the working noise is low, and moreover, the heat exchanging performance is high.

Description

technical field [0001] The invention relates to the field of air conditioning systems, in particular to a heat exchanger for an external unit of an air conditioner. Background technique [0002] The current air-conditioning outdoor unit mainly adopts finned heat exchangers, which include heat-dissipating fins and heat-exchanging copper tubes fixed with the heat-dissipating fins; The fins continuously supply air; because the overall space composed of cooling fins and heat-exchanging copper tubes is large, and the ventilation direction is single, it is necessary to use a large-power drive motor and heat-exchanging fan to ensure good heat-exchange performance; this It not only makes the external unit bulky and inconvenient to install, but also often produces relatively loud noise, which affects the rest environment. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a simple air conditioner external unit heat e...
