Example Embodiment

[0037] figure 1 is a schematic cross-sectional view of a radiant convection heat exchanger according to one embodiment of the present invention. like figure 1 shown and referenced Figure 2 to Figure 5 , 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 portion 20 has a cylindrical shape with both ends open, and is configured to absorb heat or cooling from its inner wall and radiate heat or cooling outward from its outer wall. For example, the outer contour of the cross section of the radiation heat exchange part 20 is a circle, a semicircle, a square or a fan shape. The convection heat exchange part 30 is disposed inside the radiation heat exchange part 20, and is configured to generate heat or cold energy, and transfer the heat or cold energy to the air flowing through the inner side of the radiation heat exchange part 20, ...

Abstract

The invention relates to a radiation convection type heat exchanger and an air conditioner with the same. Specifically, the radiation convection heat exchanger comprises a radiation heat exchange partwhich 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 or cold, transfer the heat or cold to air flowing through the inner side of the radiation heat exchange part and transfer the heat or cold to the inner wall surface of the radiation heat exchange part; the convection heat exchange part comprises a refrigerant pipeline which is provided with a main inlet pipe, a main outlet pipe and a plurality of refrigerant channels extending in the axial direction of the radiation heat exchange part; and one end of each refrigerant channel communicates with the main inlet pipe, and the other end of each refrigerant channel communicates with the main outlet pipe, sothat the multiple refrigerant channels are connected in parallel. On the premise of ensuring the heating or refrigerating capacity, the blowing sense of a human body can be reduced, and the thermal comfort of the human body can be 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] Existing air conditioner heat exchangers mainly heat or cool the air in the form of forced convection heat exchange, and then transfer the heat or cold energy to the room or the human body, but the heat or cold energy transfer in the form of convective heat exchange will reduce the temperature of the human body Thermal comfort, especially when 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 disc...
