AI Technical Summary

Technical Problem

In existing air-conditioning indoor units, the fin tube evaporator is large in size and has high cost, and there is still room for improvement in heat exchange performance.

Method used

It adopts a vertical cabinet-type air-conditioning indoor unit, including a housing, a radiation convection heat exchanger and a fan. The radiation convection heat exchanger consists of a radiation heat exchanger and a convection heat exchanger, and the radiation plate is used to absorb and radiate heat or cooling.

Benefits of technology

The airflow structure is optimized, the overcurrent wind speed is increased, the local resistance of the refrigerant pipeline is reduced, the heat exchange coefficient is improved, the production cost and space occupied, and the energy efficiency of the air conditioner is improved.

Abstract

The present invention relates to a cabinet-type air conditioner indoor unit. The indoor unit comprises: a shell, wherein an air inlet is provided at the lower part of the shell, an air outlet is provided at the upper part, and the front part of the shell comprises a radiation plate, which absorbs heat or cold from the rear side thereof and radiates heat or cold outward from the front side thereof; a radiation convection heat exchanger, which comprises a radiation heat exchange part and a convection heat exchange part, and is arranged in the shell; and the radiation heat exchange part is in the shape of a cylinder with both ends opened and extending in the vertical direction, and is configured to absorb heat or cold from its inner wall surface, and transfer heat or cold from its outer wall surface to the radiation plate; the convection heat exchange part is arranged on the inner side of the radiation heat exchange part, and is configured to generate heat or cold, and transfer heat or cold to air flowing through the inner side of the radiation heat exchange part, and transfer heat or cold to the inner wall surface of the radiation heat exchange part; and a fan is arranged in the shell, and is configured to at least cause the airflow to enter the inner side of the radiation heat exchange part from the air inlet, and after heat exchange with the convection heat exchange part, flow out from the air outlet.
