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, a first convection heat exchange part and a second convection heat exchange part, wherein the radiation heat exchange part adopts a tubular structure of which two ends are opened, and is arranged to absorb heat quantity or cold quantity from the inner wall surface and radiate the heat quantity or the cold quantity from the outer wall surfaces outwards; the first convection heat exchangepart is arranged on the inner side of the radiation heat exchange part, and is arranged to produce the heat quantity or the cold quantity, transmit the produced heat quantity or the produced cold quantity to air which flows past the inner side of the radiation heat exchange part and transmitting the heat quantity or the cold quantity to the inner wall surface of the radiation heat exchange part; the second convection heat exchange part is arranged to generate the heat quantity or the cold quantity, and perform heat exchange on the air flowing past the second convection heat exchange part; andthe radiation heat exchange part is arranged on the upper side or the lower side of the second convection heat exchange part. According to the radiation counter flow type heat exchanger disclosed by the invention, under the premise that the heating capacity or the refrigerating capacity are guaranteed, the wind blowing sense of the human body can be reduced, and the thermal comfort of the human body is improved; and the radiation heat exchange part and the first convection heat exchange part are mainly used for bearing sensitive heat load, and the second convection heat exchange part is mainlyused for bearing latent heat load.

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...

[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 inside of the air conditioner heat exchanger can easily cause thermal discomfort to the human body
