Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of radiation air conditioning, in particular to a radiation plate. Background Art
[0002] A radiation panel is a plate-shaped component installed indoors in an air-conditioning device. It achieves cooling by absorbing heat radiation and heating by emitting heat radiation. The existing radiation panel includes a substrate, a heat-conducting plate attached to the back of the substrate, a groove on the top wall of the heat-conducting plate, a copper medium tube for accommodating and flowing cooling medium or heating medium in the groove, one end of the copper medium tube is the medium inlet and the other end is the medium outlet. If cooling is required, the cooling medium is injected into the medium inlet, and the cooling medium flows in the copper medium tube to cool the radiation panel, so that the temperature of the radiation panel drops to a temperature lower than that of indoor objects. Indoor objects such as human bodies, furniture, walls, floors, etc. will spontaneously emit heat radiation to the substrate of the radiation panel, transferring heat to various parts of the substrate. The heat from various parts of the substrate is concentrated on the heat-conducting plate, and then transferred to the cooling medium through the copper medium tube and absorbed by the cooling medium, thereby achieving cooling. If heating is required, the heating medium is injected into the medium inlet. The heating medium flows in the medium tube and transfers the heat to the copper medium tube, and then transfers it to various parts of the base plate through the heat conduction plate, heating the base plate to a temperature higher than the temperature of the indoor objects. The base plate will spontaneously radiate heat to the indoor objects, transferring the heat to the indoor objects to achieve heating. This kind of radiation panel has a large thermal resistance because its heat transfer needs to pass through four layers of resistance, namely the base plate, the heat conduction plate, the copper medium tube and the medium, resulting in a waste of heat energy. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a radiation plate with small heat transfer resistance.
[0004] In order to solve the above technical problems, the utility model provides a radiation plate, which includes a substrate, a heat conducting plate attached to the back of the substrate, and a back of the heat conducting plate is raised to form a medium pipe for medium circulation.
[0005] Furthermore, there are multiple medium pipes, including multiple connecting pipes, and the medium pipes are connected in series to form a series pipeline. In the series pipeline, the input end of the first medium pipe is connected to the medium inlet pipe, and the output end of the last medium pipe is connected to the medium outlet pipe.
[0006] Furthermore, the utility model provides multiple heat conducting plates.
[0007] Furthermore, the cross-sectional area of the lumen of the connecting tube is smaller than that of the medium tube.
[0008] Furthermore, the radiation panel is a ceiling-mounted radiation panel.
[0009] Furthermore, the back side of the substrate is convex to form an arc shape.
[0010] Furthermore, the heat conducting plate is made of aluminum.
[0011] Furthermore, the substrate is made of aluminum.
[0012] The back of the heat conducting plate is raised to form a medium pipe for the medium to flow. If the cooling medium flows in the medium pipe, the radiation plate is cooled and the temperature of the radiation plate is lowered to a temperature lower than the temperature of the indoor object. The indoor object will spontaneously emit heat radiation to the substrate of the radiation plate and transfer the heat to the substrate. The heat on the substrate is concentrated on the heat conducting plate and transferred to the cooling medium through the heat conducting plate and absorbed by the cooling medium to achieve refrigeration. If the heating medium flows in the medium pipe, the heat is transferred to the heat conducting plate and then to the substrate through the heat conducting plate to heat the substrate and raise the temperature of the substrate to a temperature higher than the temperature of the indoor object. The substrate will spontaneously emit heat radiation to the indoor object and transfer the heat to the indoor object to achieve heating. The heat transfer of the radiation plate of the utility model only needs to pass through three layers of resistance, namely the substrate, the heat conducting plate and the medium. Compared with the prior art which needs to pass through four layers of resistance, the thermal resistance is small and heat energy can be saved. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention is further described in detail below in conjunction with specific implementation methods.
[0017] See Figure 1The radiation plate includes a substrate 1 made of aluminum. The back of the substrate 1 is convex to form an arc, which can absorb heat radiation emitted from multiple directions or emit heat radiation to multiple directions, and has high radiation efficiency. A plurality of heat-conducting plates 2 made of aluminum are attached to the back of the substrate 1. The back of each heat-conducting plate 2 is convex to form a medium pipe 21 for medium circulation. The plurality of heat-conducting plates 2 form a plurality of medium pipes 21. The radiation plate includes a plurality of connecting pipes 3. The medium pipes 21 are connected in series to form a series pipeline through the connecting pipes 3. In the series pipeline, the input end of the first medium pipe 21 is connected to the medium inlet pipe 4, and the output end of the last medium pipe 21 is connected to the medium outlet pipe 5. According to the fluid mechanics continuity equation ρ1A1v1=ρ2A2v2 (where ρ is the fluid density, A is the tube cavity cross-sectional area, and v is the fluid flow rate), when the fluid (medium) is incompressible, that is, ρ1=ρ2, the tube cross-sectional area A decreases and the medium flow rate v increases. Based on this, the utility model designs the tube cavity cross-sectional area of the connecting tube 3 to be smaller than the medium tube 21, which can increase the medium flow rate and thus improve the heat exchange efficiency.
[0018] The radiation panel of the utility model is a ceiling-mounted radiation panel. Figure 1 The base plate 1 is provided with a mounting hole 11 for connecting the ceiling connector. During installation, the ceiling connector is first installed on the indoor ceiling or ceiling, and then the base plate 1 is fixed on the ceiling connector through the mounting hole 11, so that the radiation panel is installed under the indoor ceiling or ceiling. The radiation air conditioning device includes a medium conveying device, which has an output pipe and a return pipe, wherein the output pipe is connected to the medium inflow pipe 4 of the radiation panel, and the return pipe is connected to the medium outflow pipe 5 of the radiation panel. This radiation air conditioning device has two uses, which are described in detail as follows.
[0019] The first usage is for refrigeration: the medium conveying device conveys cooling medium to the medium inlet pipe 4, and the cooling medium is preferably cooling water. The cooling medium flows into the above-mentioned series pipeline from the medium inlet pipe 4, absorbs the heat on the heat conducting plate 2, and reduces the temperature of the radiation plate to a temperature lower than the temperature of the indoor objects. Indoor objects such as human bodies, furniture, walls, floors, etc. will spontaneously emit heat radiation to the substrate 1 of the radiation plate, and transfer the heat to various parts of the substrate 1. The heat from various parts of the substrate 1 is concentrated on the heat conducting plate 2, and then transferred to the cooling medium through the medium pipe 21 and absorbed by the cooling medium to achieve refrigeration. After absorbing the heat, the cooling medium flows back to the medium conveying device through the medium outlet pipe 5 and the return pipe.
[0020] The second usage is for heating: the medium conveying device conveys the heating medium to the medium inlet pipe 4, and the heating medium flows from the medium inlet pipe 4 into the above-mentioned series pipeline, transfers the heat to the medium pipe 21, and then transfers it to various parts of the substrate 1 through the heat conducting plate 2, heating the substrate 1, and raising the temperature of the substrate 1 to a temperature higher than the temperature of the indoor object. The substrate 1 will spontaneously emit heat radiation to the indoor object, transfer the heat to the indoor object, and achieve heating. After the heating medium transfers the heat to the medium pipe 21, it flows back to the medium conveying device through the medium outlet pipe 5 and the return pipe.
[0021] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
