Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, and more specifically to a high-efficiency single crystal photovoltaic component heat dissipation structure. Background Art

[0002] Monocrystalline photovoltaic modules are power generation units that are formed by packaging solar cells made of monocrystalline silicon wafers in series and parallel. Monocrystalline silicon has the characteristics of high purity, uniform structure, and high photoelectric conversion efficiency. Therefore, photovoltaic modules made from it are usually superior to polycrystalline silicon photovoltaic modules in terms of energy conversion efficiency.

[0003] The working principle of monocrystalline photovoltaic modules is to produce photovoltaic effect when sunlight shines on the silicon wafer on its surface, thereby directly converting light energy into electrical energy; this type of module is widely used in solar power stations, distributed photovoltaic power generation systems, photovoltaic building integration (BIPV), and various types of solar chargers and portable power supplies.

[0004] There is an existing (application number: CN202021699320.8, a photovoltaic and thermal energy concentrator), in which the "photoelectric conversion layer adopts a single crystal photovoltaic module", and a "heat dissipation component" is used on the backlight side of the single crystal photovoltaic module, and a "copper tube" is used in the "heat dissipation component";

[0005] At the same time (application number: CN202321121149.6, a high-efficiency heat dissipation photovoltaic power generation panel), a "copper plate" is used on the backlight side of the "solar panel" to absorb and conduct heat;

[0006] Although copper is a material with strong heat absorption and thermal conductivity, its surface is easily oxidized by oxygen to form a layer of copper oxide (CuO) when used for a long time or exposed to air, which manifests as green or black rust on the surface. This oxide film will reduce the thermal conductivity of copper and affect its efficiency in the heat dissipation system, thereby affecting the heat dissipation of single-crystal photovoltaic modules, and further reducing power generation efficiency and module life. Utility Model Content

[0007] The purpose of the utility model is to provide a high-efficiency single crystal photovoltaic module heat dissipation structure in order to solve the above technical problems.

[0008] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0009] The utility model proposes a high-efficiency single crystal photovoltaic module heat dissipation structure, comprising a single crystal photovoltaic module body, a copper plate fixedly arranged on the outer side of the single crystal photovoltaic module body, a heat conductive convex strip fixedly arranged on the outer side of the copper plate, and a nickel-plated layer fixedly arranged on the outer side of the copper plate and the heat conductive convex strip.

[0010] As a preferred technical solution of the utility model, the copper plate and the heat-conducting convex strip are integrally formed.

[0011] As a preferred technical solution of the utility model, the heat-conducting convex strips are provided in multiple groups and are evenly distributed on the outer side of the copper plate.

[0012] As a preferred technical solution of the utility model, one side of the copper plate is connected to the other side thereof via multiple groups of heat-conducting convex strips.

[0013] As a preferred technical solution of the utility model, a diamond-like carbon coating is bonded and fixed to the outer side of the nickel-plated layer.

[0014] As a preferred technical solution of the utility model, an oxide ceramic coating is bonded and fixed to the outer side of the diamond-like carbon coating.

[0015] The beneficial effects of the utility model are as follows:

[0016] By laminating a nickel-plated layer 4 on the copper plate 2, the nickel-plated layer 4 can improve the corrosion resistance and oxidation resistance of the surface of the copper plate 2, thereby maintaining a good heat conduction effect; the diamond-like carbon coating 5 arranged on the surface of the nickel-plated layer 4 has an extremely low thermal expansion coefficient and a high thermal conductivity, which helps to quickly transfer heat, reduce thermal resistance, and thus improve heat dissipation efficiency; the oxide ceramic coating 6 arranged on the surface of the diamond-like carbon coating 5 has high thermal stability and low thermal conductivity, can play a role in heat insulation to a certain extent, and has a certain reflective ability for thermal radiation, reduces the transfer of heat to unnecessary directions, and helps to dissipate heat more concentratedly and effectively.

[0021] A copper plate 2 is fixedly attached to the outer side of the monocrystalline photovoltaic module body 1 (as shown in the figure, according to the above, the copper plate 2 is attached to the bottom of the monocrystalline photovoltaic module body 1) (the copper plate 2 itself is an excellent thermal conductor with a high thermal conductivity, which can quickly conduct the heat generated inside to the external environment);

[0022] The outer side of the copper plate 2 is fixed with a heat-conducting convex strip 3 (the heat-conducting convex strip 3 can be made of copper or other materials) to increase the heat-conducting area and improve the efficiency;

[0023] The copper plate 2 and the heat-conducting convex strip 3 are integrally formed, which is convenient to manufacture;

[0024] The heat-conducting convex strips 3 are provided in multiple groups and are evenly distributed on the outside of the copper plate 2 (the multiple groups of heat-conducting convex strips 3 can be evenly distributed from left to right at the bottom of the copper plate 2 as shown in the figure);

[0025] One side of the copper plate 2 is connected to the other side thereof by a plurality of groups of heat-conducting ridges 3 (as shown in the figure, that is, at the front and rear sides of the bottom end of the copper plate 2, the flow is not blocked by the plurality of groups of heat-conducting ridges 3, so that the air flow can be carried out, thereby improving the heat dissipation effect).

[0026] A nickel-plated layer 4 is fixedly disposed on the outer side of the copper plate 2 and the heat-conducting ridge 3 (the nickel-plated layer 4 may be formed by electroplating or the like, which can improve the corrosion resistance of the surface of the copper plate 2 and the heat-conducting ridge 3, prevent copper from being oxidized and corroded in a humid or chemical environment, thereby maintaining a good heat conduction effect).

[0029] Excellent hardness and wear resistance: The diamond-like carbon coating 5 has a high hardness close to that of diamond, which can significantly improve the wear resistance and scratch resistance of the material surface, and is very effective in preventing the copper plate 2 from being lost in a friction and wear environment;

[0030] Good chemical stability: The diamond-like carbon coating 5 has good corrosion resistance and oxidation resistance, and can protect the copper plate 2 from being corroded by air, moisture or other chemicals, and can maintain stable performance in extreme environments;

[0031] Good adhesion: The diamond-like carbon coating 5 has a good adhesion with the middle layer and is not easy to peel off, ensuring the overall stability and durability of the multi-layer structure.

[0032] Embodiment 3:

[0033] like Figure 1 As shown, the difference from Example 2 is that: it also includes that an oxide ceramic coating 6 is bonded and fixed to the outer side of the diamond-like carbon coating 5 (the oxide ceramic coating 6 can be formed by a spraying process or the like, has high thermal stability and low thermal conductivity, can play a role in heat insulation to a certain extent, and has a certain reflective ability for thermal radiation, reduces the transfer of heat to unnecessary directions, and helps to dissipate heat more concentratedly and effectively).
