[0047] like Figure 1-3As shown, the present application provides an anti-condensation radiation component, including a radiation panel layer 100, a heat exchanger layer 200, a reflective layer 300 and a thermal insulation layer 400 stacked in sequence from top to bottom; the heat exchanger layer 200 includes a first main pipe 210, a plurality of heat exchange branch pipes 220 and a second main pipe 230; the plurality of heat exchange branch pipes 220 are arranged side by side; the first main pipe 210 is connected to one end of the heat exchange branch pipe 220, and the second main pipe 230 is connected to the other end of the heat exchange branch pipe 220. The pipes used in the heat exchanger layer 200 are copper pipes with good thermal conductivity, high heat exchange efficiency, and are installed close to the radiation panel 100, which can quickly transfer heat to the radiation panel 100. The multiple heat exchange branch pipes 220 in the heat exchanger layer 200 are arranged in parallel. Compared with the traditional S-shaped heat exchange pipes connected in series, the above-mentioned parallel short-stroke heat transfer method has a short flow distance, less heat loss, a small difference in inlet and outlet temperature, and a more uniform heat distribution. The heat exchanged to the radiation panel layer 100 is balanced, so that the temperature on the entire radiation panel layer 100 is uniform, avoiding condensation due to temperature differences on the radiation panel layer 100;

[0048] like Figure 4 As shown, in some embodiments provided by the present application, a plurality of heat exchange branch pipes 220 are arranged side by side in a single layer. Figure 5 As shown, in some other embodiments provided by the present application, multiple heat exchange branch pipes 220 are arranged in double layers side by side. The double-layer arrangement of the heat exchange branch pipes 220 further reduces the temperature difference of the heat exchange layer, so that the circulation in the heat exchange layer maintains a consistent temperature, the heat radiated to the radiation panel layer 100 is evenly distributed, and the effect of reducing condensation on the radiation panel layer 100 is better.

[0049] In some embodiments provided in the present application, the radiation panel layer 100 includes a radiation panel 110 and an external radiation coating; the external radiation coating adopts a porous structure with good air permeability and strong surface activity, and titanium dioxide is added to the external radiation coating. The external radiation coating has good transmittance, high absorptivity and low reflectivity for infrared radiation of the human body with a wavelength of 8-12 microns. Both the radiation panel 110 and the external radiation coating can be in a radiation working state at the same time. The porous structure can reduce the temperature difference between the inner and outer surfaces of the external radiation coating, and the porous structure can store a certain amount of water vapor, delaying the occurrence of condensation.

[0050] like Figure 2 , Figure 6 and Figure 7As shown, in some embodiments provided by the present application, there is a cavity between the radiation panel layer 100 and the reflective layer 300, and the radiation panel 110 is provided with a plurality of through holes 111. A plurality of through holes 111 are distributed on the radiation panel 110, and combined with the cavity structure between the radiation panel layer 100 and the reflective layer 300, cold and hot air can pass through the radiation panel 100, so that the radiation component can perform convective heat transfer at the radiation panel 100 in addition to radiation heat transfer, thereby preventing condensation of the radiation panel under refrigeration conditions. Preferably, the through holes 111 are evenly distributed at both ends of the radiation panel 110. The above embodiment is suitable for anti-condensation radiation components to be installed on indoor walls.

[0051] like Figure 8 As shown, in some embodiments provided by the present application, the anti-condensation radiation component also includes an energy storage and heat-saturating layer 500; the energy storage and heat-saturating layer 500 is arranged between the radiation panel layer 100 and the reflective layer 300; the energy storage and heat-saturating layer 500 tightly wraps the heat exchanger layer 200; the energy storage and heat-saturating layer 500 is tightly attached to the lower side of the radiation panel 110 and the upper side of the reflective layer 300 respectively. The energy storage and heat-saturating layer 500 can be selected as a material with good thermal conductivity to store excess heat energy and delay condensation to a certain extent. The energy storage and heat-saturating layer can use a gelling energy storage agent with good thermal conductivity, which is suitable for the anti-condensation radiation component to be installed on the indoor ceiling or floor; it can also use microporous ceramics with good thermal conductivity, a mixture of pebbles and coarse sand, or other similar functional materials, which are suitable for the anti-condensation radiation component to be installed on the indoor floor. Correspondingly, the radiation panel layer 100 at this time is a tile layer. The energy storage heat-saturating layer 500 is arranged between the radiation panel layer 100 and the reflective layer 300; the energy storage heat-saturating layer 500 tightly wraps the heat exchanger layer 200. The pipes of the heat exchanger layer 200 are completely wrapped by the filling material with good thermal conductivity in the energy storage heat-saturating layer 500, so that the heat energy distribution on the entire radiation component is more uniform, and there will be no local overheating or overcooling, which to a certain extent alleviates the condensation phenomenon that may occur due to local overcooling. In this embodiment, the energy storage heat-saturating layer 500 is tightly attached to the lower side of the radiation panel 110 and the upper side of the reflective layer 300, respectively. The heat conduction between the radiation panel 110 and the energy storage heat-saturating layer 500 in the anti-condensation radiation component is further improved.

[0052] like Figure 9-11 As shown, in some embodiments provided by the present application, the heat exchanger layer 200 further includes a grid fixing member 240, which is formed by interweaving the grid fixing members 240; the grid fixing members 240 are inserted and connected to fix the heat exchange branch pipes 220. Fig.10 As shown, when a plurality of heat exchange branch pipes 220 are arranged side by side in a single layer; the heat exchange branch pipes 220 of this layer are interlaced and connected with the grid fixing member 240; Fig.11As shown, when multiple heat exchange branch pipes 220 are arranged side by side in double layers; any one layer of heat exchange branch pipes 220 is selected to be interlaced and connected with the grid fixing member 240; the above two types of heat exchange branch pipes 220 are arranged side by side in single and double layers and interlaced and connected with the grid fixing member 240, the structure of the entire anti-condensation radiation component is stable, and the layers are kept stably connected to avoid condensation caused by uneven heat transfer due to gaps between the layers.

[0053] The above is a detailed introduction to an anti-condensation radiation component provided by the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the core idea of ​​the present application.
