Abstract
Description
Technical Field
[0001] The utility model relates to an overlapping tile type solar photovoltaic and solar thermal integrated component. Background Art
[0002] Solar photovoltaic and solar thermal technology combines photovoltaic and solar thermal, which can achieve a high solar energy utilization rate. The utilization of solar energy is mainly divided into two methods: solar thermal utilization and photovoltaic utilization. Traditional solar photovoltaic systems and solar thermal systems usually exist independently, not only occupying a large area but also having low utilization efficiency.
[0003] The conversion efficiency of existing solar cells is small. Generally, only a small part of the light energy can be converted into available electric energy, and the rest is converted into heat energy. During the conversion process, as the heat energy increases, the temperature of the battery continuously rises, and the photoelectric conversion efficiency will also be greatly reduced.
[0004] Therefore, a component that can reduce the battery temperature and increase the power generation efficiency is needed. Summary of the Utility Model
[0005] The purpose of the utility model is to provide an overlapping tile type solar photovoltaic and solar thermal integrated component, which reduces the influence of heat energy on the battery conversion efficiency and greatly improves the power generation power of the component.
[0006] The technical solution to achieve the purpose of the utility model is: the utility model has a packaging backboard, a second adhesive film, a battery cell, a first adhesive film and glass. The packaging backboard, the second adhesive film, the battery cell, the first adhesive film and the glass are laid in sequence. It also includes a water cooling plate, which is located between the second adhesive film and the packaging backboard. Both sides of the water cooling plate act on the second adhesive film and the packaging backboard respectively. The water cooling plate includes a flat plate facing the second adhesive film and a stamping plate facing the packaging backboard. The flat plate and the stamping plate are arranged oppositely and are fixedly connected to each other. The stamping plate is provided with a water channel, which is located between the flat plate and the stamping plate. An inlet and an outlet are communicated with the water channel.
[0007] Furthermore, the stamping plate is provided with a plurality of bumps arranged on the water channel and evenly arranged along the extension direction of the water channel. The protruding parts of each bump extend towards the flat plate.
[0008] Furthermore, the water channel is a strip-shaped pipeline. The inlet is arranged at one end of the water channel, and the outlet is arranged at the other end of the water channel.
[0009] Furthermore, a thermal conductive silica gel is also arranged between the second adhesive film and the water cooling plate. One side of the thermal conductive silica gel acts on the second adhesive film, and the other side acts on the flat plate.
[0010] Furthermore, the water channel is arranged in an S-shaped distribution.
[0011] Furthermore, a water inlet interface is fixedly provided at the water inlet, and a water outlet interface is fixedly provided at the water outlet.
[0012] The utility model has the following positive effects: (1) The water-cooled plate of the utility model is located between the second adhesive film and the encapsulation backplane, and the water channel is located between the flat plate and the stamping plate; the water-cooled plate can utilize the water channel to take out the heat generated by the battery cells through the water flow in the water channel, reducing the influence of heat energy on the battery conversion efficiency. The power generation conversion efficiency is much higher than that of ordinary photovoltaic modules under the same area, greatly improving the power generation power of the module.
[0013] (2) The water channel of the utility model is a strip-shaped pipeline. An inlet is communicated and provided at one end of the water channel, and an outlet is communicated and provided at the other end of the water channel. Through the transportation of water flow through the inlet and the outlet, the solar photovoltaic power generation and the solar thermal utilization are combined together, improving the utilization rate of solar energy while obtaining available hot water and electricity.
[0014] (3) A plurality of bumps are provided on the stamping plate of the utility model. The bumps are arranged on the water channel and are evenly arranged along the extending direction of the water channel. Each bump extends towards the flat plate. The bumps can play a role in disturbing the flow to strengthen heat exchange and at the same time enhance the strength of the cold plate. After the flow is disturbed, the water flow will pass through a longer channel, stay in the water channel for a longer time, take away more heat, and improve the battery conversion efficiency.
[0015] (4) A heat-conducting silica gel is further provided between the second adhesive film and the water-cooled plate of the utility model. One side of the heat-conducting silica gel acts on the second adhesive film, and the other side of the heat-conducting silica gel acts on the flat plate; the heat-conducting silica gel can better conduct the heat generated by the battery cells to the water-cooled plate, increasing the heat conduction efficiency.
[0016] (5) The water channel of the utility model is arranged in an S-shaped distribution, forming a longer water flow channel, which can allow more water flow to conduct heat.
[0017] (6) The utility model adopts the form of a shingled solar cell module, further improving the space utilization rate and the photoelectric conversion efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The water-cooling plate 6 includes a flat plate 61 facing the second adhesive film 2 and a stamping plate 62 facing the packaging backplane 1. The flat plate 61 and the stamping plate 62 are arranged opposite to each other and are fixedly connected to each other. A water channel 7 is provided on the stamping plate 62.

The thermal conductive silica gel 9 can better conduct the heat generated by the battery cell 3 to the water-cooling plate 6, increasing the heat conduction efficiency; the thermal conductive silica gel 9 also has a certain viscosity, which can ensure that the water-cooling plate 6 is in close contact with the second adhesive film 2, and the heat can be conducted better.
[0029] The water channel 7 is arranged in an S shape. The S-shaped channel can form a longer water flow channel, allowing more water flow for heat conduction.
[0030] An inlet interface 711 is fixedly provided at the water inlet 71, and an outlet interface 721 is fixedly provided at the water outlet 72.
