Radiation counter flow type heat exchanger and air conditioner with same

Abstract

The invention relates to a radiation counter flow type heat exchanger and an air conditioner with the same. The radiation counter flow type heat exchanger specifically comprises a radiation heat exchange part and a convection heat exchange part, wherein the radiation heat exchange part adopts a tubular structure of which two ends are opened, and absorbs heat quantity or cold quantity from the inner wall surface and radiates the heat quantity or the cold quantity from the outer wall surfaces outwards; the convection heat exchange part is arranged on the inner side of the radiation heat exchangepart, and is arranged to generate the heat quantity or the cold quantity; the convection heat exchange part is provided with a plurality of heat exchange plates; each heat exchange plate comprises afirst edge and a second edge which extend in the axial direction along the radiation heat exchange part; each first edge is arranged at the middle part of the space on the inner side of the radiationheat exchange part; each second edge is connected the inner wall surface of the radiation heat exchange part; the heat exchange plates are sequentially arranged in the circumferential direction of theradiation heat exchange part; a plurality of heat dissipation fins which are sequentially arranged in the radial direction of the radiation heat exchange part are arranged between every two adjacentheat exchange plates; and the arraying density of the heat dissipation fins between the every two adjacent heat exchange plates is not the same.

Description

technical field [0001] The invention relates to the field of refrigeration and heating, in particular to a radiation convection heat exchanger and an air conditioner with the same. Background technique [0002] The existing air conditioner heat exchanger mainly heats or cools the air in the form of forced convection heat exchange, and then transfers the heat or cold to the room or the human body. However, the heat transfer in the form of convective heat exchange will reduce the thermal comfort of the human body. Especially when a higher heating or cooling capacity is required, the high wind blowing from the heat exchanger of the air conditioner can easily cause thermal discomfort to the human body. Contents of the invention [0003] The purpose of the first aspect of the present invention is to overcome at least one defect of the existing heat exchangers, and provide a radiation convection heat exchanger, which can significantly reduce the thermal discomfort of the human b...
