Problems solved by technology

In this process, since the heat dissipation pipe is fixed, the air inlet airflow passes through the surrounding surface formed by the heat exchange pipe in a roughly orthogonal manner, and the thermal contact volume and time with the heat exchange pipe are relatively limited, resulting in limited heat transfer efficiency. , so that a large amount of heat or heat accumulates at the heat exchange tube, which limits its energy-saving effect

Abstract

The invention provides a high-efficiency indoor unit of an air conditioner. The high-efficiency indoor unit comprises a base shell; a cross-flow fan driven by a driving motor is horizontally arrangedinside the base shell; coiled heat exchange tubes which are connected by vertical cooling fins are arranged at the rear upper part of the cross-flow fan in a half-surrounding manner; the cross-flow fan is made of a metal material; inner rings, uniformly distributed along the axis of the cross-flow fan, of three or more fan bearings are fixedly arranged together with the periphery of the cross-flowfan; and an outer ring of each fan bearing has heat-conducting contact with the corresponding coiled heat exchange tube. The indoor unit of the air conditioner can improve the heat exchange efficiency of air inside the base shell to a relatively high extent so as to improve the energy saving effect of the air conditioner.

Description

technical field [0001] The present invention relates to the field of air conditioners, in particular to an air conditioner inner unit. Background technique [0002] The current air-conditioning internal unit mainly includes a base shell, a heat exchange tube, and a fan; the fan is a long cylindrical plastic cross-flow fan, and the heat exchange tube is a serpentine tube that surrounds the back and upper part of the cross-flow fan, and is stabilized by a heat sink. ; During the rotation process of the cross-flow fan driven by the motor, the air entering from the rear of the base shell of the air conditioner passes through the heat exchange tube and then is sent out by the cross-flow fan, thereby completing the air heat exchange process. In this process, since the heat dissipation pipe is fixed, the air intake air passes through the surrounding surface formed by the heat exchange pipe in a roughly orthogonal manner, and the thermal contact volume and time with the heat exchang...
