Problems solved by technology
[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

Embodiment Construction
[0027] figure 1 is a schematic cross-sectional view of a radiation convective heat exchanger according to an embodiment of the present invention. like figure 1 As shown, the embodiment of the present invention provides a radiation convection heat exchanger, including a radiation heat exchange part 20 and a convection heat exchange part 30 . The radiation heat exchange part 20 is in the shape of a cylinder with both ends open, and is configured to absorb heat or cold from its inner wall and radiate heat or cold from its outer wall. For example, the outer contour of the cross section of the radiation heat exchange part 20 is circular, semicircular, square or fan-shaped. The convective heat exchange part 30 is arranged inside the radiation heat exchange part 20, configured to generate heat or cold energy, and transfer the heat or cold energy to the air flowing through the inside of the radiation heat exchange part 20, and transfer the heat or cold energy to the air flowing thro...

The invention relates to a radiation convection type heat exchanger and an air conditioner with the same. Specifically, the radiation convection type heat exchanger comprises a radiation heat exchangepart which is in a cylindrical shape with two open ends and configured to absorb heat or cold from the inner wall surface of the radiation heat exchange part and outwards radiate heat or cold from the outer wall surface of the radiation heat exchange part, and a convection heat exchange part which is arranged on the inner side of the radiation heat exchange part and configured to generate heat orcold; the convection heat exchange part is provided with a plurality of heat exchange plates; each heat exchange plate is provided with a first edge and a second edge extending in the axial directionof the radiation heat exchange part; the first edges are arranged in the middle of the space inside the radiation heat exchange part, and the second edges are connected with the inner wall surface ofthe radiation heat exchange part; the heat exchange plates are sequentially arranged in the circumferential direction of the radiation heat exchange part; a plurality of radiating fins sequentially arranged in the radial direction of the radiation heat exchange part are arranged between every two adjacent heat exchange plates; and each radiating fin is in an arc shape arched towards the radial outer side of the radiation heat exchange part. The blowing feeling of a human body is reduced, and the thermal comfort of the human body is improved.
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...
