Embodiment 1

[0022] like figure 1 A heat collecting plate includes a plate body 1 and a working medium flow channel 2 formed in the plate body. The plate body 1 is provided with a functional surface 11 for absorbing heat, and a graphene heat absorbing film 111 is provided on the surface of the functional surface 11 . Graphene can not only absorb visible light and weak light emitted by the sun, but also absorb invisible infrared light and ultraviolet light. The graphene heat-absorbing film 111 covered on the surface of the functional surface 11 can absorb more light energy in the same heating time with the same heating area, so that the heat collecting plate products can be miniaturized and miniaturized, thus better The connection and integration of land and buildings. At the same time, graphene has good ultra-high thermal conductivity, which improves the heating efficiency of the heating plate. In addition, the graphene material has extremely high mechanical strength, which can effective...

Embodiment 2

[0026] like figure 2 , the working medium channel 2 can be distributed in a serpentine shape in the plate body. The length of the working medium flow channel 2 is increased to improve the heating efficiency.

Embodiment 3

[0028] like image 3 , the working medium flow channel 2 may also have multiple, and the multiple working medium flow channels 2 are independent of each other. And a graphene heat conduction layer 3 is arranged between two adjacent working medium flow channels.

[0029] In addition, the plate body 1 can also be made of materials added with graphene particles. Graphene's good ductility, extremely high mechanical strength and ultra-high thermal conductivity improve the processing characteristics of the heat collector plate. The heat collector plate can be thinner and lighter, which greatly facilitates installation and reduces the risk factor of high-altitude operations.

Abstract

The invention relates to the technical field of heating, in particular to a heat collecting plate. The heat collecting plate comprises a plate body and a working medium flow channel formed in the plate body, and the plate body is provided with a function face used for absorbing heat. The heat collecting plate is characterized in that a graphene heat absorbing film is arranged on the surface of the function face. Graphene can absorb not only visible light and weak light emitted by the sun, but also invisible infrared light and ultraviolet light; more luminous energy can be absorbed through the same heating area within the same heating time, a heat collecting plate product can be miniature, and therefore butt joint and integration of the heat collecting plate and a building can be better achieved. Meanwhile, the graphene has good ultrahigh heat conducting capacity, and the heating efficiency of a heating plate is improved. In addition, the graphene has ultrahigh mechanical strength, and therefore the strength of the plate body of the heat collecting plate can be effectively improved; the defects that working medium leakage, personal injuries and the like are prone to being caused by detonation when the pressure of working media of a traditional heat collecting plate is too high are overcome.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to a heat collecting plate. Background technique [0002] The collector plate absorbs energy from the surrounding environment and converts it into heat for heating. The current heat collectors are mainly solar heat collectors that collect light energy in the environment. However, due to the limited range of solar heat collectors that can absorb light, the conversion efficiency of sunlight is low. Heating can only be done in a sunny environment, and a larger heating area is required to achieve the desired heating effect. The recently emerging heteropolymer heating plate uses the chaotic effect to collect the temperature difference in the environment for heating, which overcomes the limitation that solar energy can only be heated in a sunny environment, but its heating efficiency is still low, and it still needs more energy. Large heating area for heating. Contents of the inventio...
