Description

Technical Field

[0001] This utility model relates to the field of indoor radiant cooling and heating technology, specifically a cold and heat radiant panel. Background Technology

[0002] Current indoor temperature control systems mainly rely on two separate devices—floor heating and air conditioning—to achieve heating and cooling functions. However, both technologies currently have certain limitations:

[0003] Underfloor heating can be divided into underfloor heating systems and radiator systems. Both mainly generate heat through ground heat radiation. Although they can provide a uniform thermal environment, their functions are limited and they can only heat from one dimension. There is room for improvement in overall heating efficiency. At the same time, they rely on gas boilers or electric heating equipment, resulting in high energy costs. Air conditioning systems achieve cooling through air convection, but forced air circulation can easily lead to indoor humidity imbalance and resuspension of air pollutants. Furthermore, direct cold air can easily cause symptoms such as dry respiratory mucosa and decreased immunity in the elderly and children.

[0004] Both underfloor heating and air conditioning rely on the principle of thermal radiation, that is, high-temperature objects actively release energy to low-temperature objects or low-temperature objects absorb energy from high-temperature environments. Air conditioning adds a blowing component to increase the flow speed of high-temperature or low-temperature air.

[0005] Chinese patent CN218385389U discloses an aluminum tube composite aluminum cooling plate that can expand the heat dissipation area. It cools lithium batteries and other devices by embedding cooling pipes inside the aluminum plate. Chinese patent CN220017582U discloses a heating and cooling radiant panel and an air conditioning system. It applies the former to an air conditioning system. However, the coil structure inside the heating and cooling radiant panel is more complicated. The return water pipe, supply water pipe, branch pipe and parallel pipe are all integrated into the heating and cooling radiant panel. The coil has an overlapping upper and lower layer structure, which greatly increases the thickness of the heating and cooling radiant panel. At the same time, it is not convenient to maintain the main pipes such as return water pipe and supply water pipe inside the heating and cooling radiant panel. Utility Model Content

The metal heat-conducting sheet is located between the limiting groove and the liquid guiding pipe and can fit with the liquid guiding pipe and the outer decorative plate.

[0011] Furthermore, the metal heat-conducting sheet includes a circular segment and two L-shaped segments, the two L-shaped segments being connected to the circular segment, the L-shaped segments being able to fit against one side of the outer decorative panel, one side of the circular segment fitting against the liquid guide tube, and the other side of the circular segment fitting against the limiting groove.

In case of abnormality, only the damaged radiant heat-insulating panel needs to be replaced, reducing the overall maintenance cost.

[0019] 2. By setting metal heat-conducting fins inside the inner insulation positioning plate, which can contact the liquid guide pipe and the outer decorative plate respectively through their unique structure, the heat exchange area between the two is increased, thereby improving the heat exchange efficiency to a certain extent.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] like Figure 1 and Figure 2As shown, a heat-radiating heat-dissipating panel suitable for indoor use includes an outer decorative panel 1 and an inner heat-insulating positioning panel 2, wherein the inner heat-insulating positioning panel 2 can be inserted into the outer decorative panel 1. The inner heat-insulating positioning panel 2 and the outer decorative panel 1 are detachably connected. A liquid guide pipe 3 is provided inside the inner heat-insulating positioning panel 2, and a heat exchange liquid is introduced into the liquid guide pipe 3. The liquid guide pipe 3 can heat up and / or cool down the outer decorative panel 1. One end of the liquid guide pipe 3 is connected to an infusion pipe 7, and the other end of the liquid guide pipe 3 is connected to a return pipe 8. The return pipe 8 and the infusion pipe 7 are located outside the inner heat-insulating positioning panel 2.

[0036] The purpose of this design is to provide a radiant heat and cold panel, the main body of which includes an outer decorative panel and an inner insulation positioning panel, and to achieve a detachable connection, which facilitates the installation of the radiant heat and cold panel and subsequent maintenance of the internal components of the panel. At the same time, only the liquid guide pipe for heat exchange is inside the panel, while the main pipes such as the return liquid pipe and the infusion pipe are external. In case of abnormality, only the damaged radiant heat and cold panel needs to be replaced, reducing the overall maintenance cost.

[0037] It should also be noted that both cold radiation and thermal radiation are forms of energy transfer. Thermal radiation is the active release of energy from a high-temperature object to a low-temperature object. In this embodiment, a high-temperature heat exchange fluid is introduced into the cold and hot radiation panel, causing the temperature of the exterior decorative panel to rise, thereby generating thermal radiation that raises the temperature of the indoor area. Cold radiation, on the other hand, is the opposite of thermal radiation. It is the absorption of energy from a high-temperature environment by a low-temperature object. In this embodiment, a low-temperature heat exchange fluid is introduced into the cold and hot radiation panel, causing the temperature of the exterior decorative panel to drop, thereby generating cold radiation that lowers the temperature of the indoor area.

[0038] At the same time, such as Figure 3 As shown, a detachable structure of inner insulation positioning plate 2 and outer decorative plate 1 is provided. The edge of the outer decorative plate 1 hooks inward to form a structure similar to a hook keel 11. The outer decorative plate 1 has a placement cavity 4 inside. During installation, the inner insulation positioning plate 2 is placed in the placement cavity 4, and the hook keel limits the position of the insulation positioning plate inside the outer decorative plate.

[0039] like Figure 4 As shown, another detachable structure of inner insulation positioning plate 2 and outer decorative plate 1 is provided. The edge of the outer decorative plate 1 is provided with a clip 12 or a similar protruding block structure. The outer decorative plate 1 is provided with a placement cavity 4. During installation, the inner insulation positioning plate 2 is placed in the placement cavity 4, and the clip 12 can limit the position of the insulation positioning plate inside the outer decorative plate.

[0040] like Figure 5 As shown, a third type of detachable structure for the inner insulation positioning plate 2 and the outer decorative plate 1 is provided, which is in Figure 3An additional hook keel 11 structure is added to the existing structure, thus forming a double hook keel 13, which can be connected to the installation parts on the interior ceiling to install the hot and cold radiation panels on the interior ceiling.

[0041] In this embodiment, the liquid guide tube 3 is coiled and can fit against one side of the outer decorative panel 1.

[0042] It should be noted that, in order to increase the length of the liquid guide tube 3 in the hot and cold radiation panel, it can be set in a barbell core concentric stacked alternating serpentine offset outlet coil structure. Here, "barbell core" refers to the barbell-shaped main body of the central fluid channel, "concentric stacking" refers to the arrangement of multiple layers of pipes around the same central axis, "alternating serpentine" refers to the odd and even layers of flow channels having opposite directions, presenting an overall "zigzag" path, and "offset outlet" refers to the main fluid outlet being off the central axis to facilitate the flow of heat exchange liquid into and out on the same side, thereby ensuring that the whole structure is a single layer and reducing the thickness of the hot and cold radiation panel.

[0043] In this embodiment, a limiting groove 5 is provided on the side of the inner insulation positioning plate 2 facing the outer decorative plate 1. The liquid guiding pipe 3 is placed in the limiting groove 5. A metal heat-conducting sheet 6 is also provided on the side of the inner insulation positioning plate 2 facing the outer decorative plate 1. The metal heat-conducting sheet 6 is located between the limiting groove 5 and the liquid guiding pipe 3 and can fit with the liquid guiding pipe 3 and the outer decorative plate 1. The metal heat-conducting sheet 6 includes a circular segment and two L-shaped segments. The two L-shaped segments are connected to the circular segment. The L-shaped segments can fit with one side of the outer decorative plate 1. One side of the circular segment fits with the liquid guiding pipe 3, and the other side of the circular segment fits with the limiting groove 5.

[0044] The purpose of this design is to increase the heat exchange area between the two by setting metal heat-conducting sheets inside the inner insulation positioning plate. These sheets have a unique structure that allows them to contact the liquid guide pipe and the outer decorative plate respectively, thereby improving the heat exchange efficiency to a certain extent.

[0045] In this embodiment, as Figure 6 As shown, an infusion branch tube 9 is provided on the infusion tube 7, and the infusion tube 7 is connected to one end of the infusion guide tube 3 through the infusion branch tube 9.

[0046] The return pipe 8 is provided with a return branch pipe 10, and the return pipe 8 is connected to the other end of the guide pipe 3 through the return branch pipe 10.

[0047] The purpose of this design is to connect the infusion pipe and return pipe to the guide pipe by setting infusion branch pipe and return branch pipe. During maintenance, only the corresponding infusion branch pipe and return branch pipe need to be disconnected, without affecting the use of other hot and cold radiant ceiling panels.

[0048] like Figure 7As shown, the hot and cold radiant ceiling panels are installed side by side and connected to the infusion pipe and return pipe during use, so that the indoor ceiling area is completely filled.

[0049] In this embodiment, the heat exchange fluid is deionized water or mineral oil, and the internal insulation positioning plate is a foam board.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
