Embodiment Construction

[0017] figure 1 The structure of a longitudinal section of a monolithic solar curtain wall 14 is shown. The front of the solar cell module 6 is completely attached to the inner surface of the hollow glass 7 to receive the light from the sun. And on the back side of the solar cell module 6, a heat dissipation plate 4 that can conduct heat and play the role of fixing the return-shaped water pipe 3 is bonded by the adhesive layer 5 . The area of ​​this radiating plate 4 should be the same as the area of ​​the solar cell module 6, and one side of the radiating plate 4 is a plane, while the other side is provided with wavy spacer protrusions (see Figure 4 ), a return-shaped water pipe 3 is fixed in the semicircular groove or U-shaped groove along the length direction of the protrusion, and the contact of each protrusion and the return-shaped water pipe 3 also has an adhesive layer 5. Said adhesive layer 5 is a thermally conductive adhesive with thermal conductivity, such as HY58...

Abstract

The invention relates to a water circulation cooling device of solar curtain walls, comprising a solar battery assembly (6). The water circulation cooling device of solar curtain walls is characterized in that an adhesion layer (5) is arranged between a plane at one side of a cooling plate (4) in each solar curtain wall and the solar battery assembly (6), wherein a circuitous water pipe (3) is supported by the cooling plate (4), a water outlet pipe (11) and a hot water pipe (9) of the circuitous water pipe (3) are communicated, and a water inlet pipe (12) and a cold water pipe (10) of the circuitous water pipe (3) are communicated; and the solar battery assembly (6), the cooling plate (4) for supporting the circuitous water pipe (3), and the adhesion layer (5) are encapsulated in hollow glass (7). The solar battery assembly can be kept at a suitable working temperature by the structure so as to greatly improve the photoelectric conversion efficiency of the solar battery assembly, solve the technical problem of low working efficiency of a BIPV (Building Integrated Photovoltaic) solar battery, provide a user with hot water and achieve the comprehensive utilization aims of saving energy and reducing emission.

Description

technical field [0001] The invention relates to a water circulation cooling device for a solar curtain wall. Background technique [0002] Solar cells emit high heat during operation. Usually, when solar cells work at an average outdoor temperature of 20°C, the normal operating temperature (NOCT) of the cell is about 40-45°C. Part of the heat is released from the back of the solar cell module. . However, in the structure of building photovoltaic integration, the solar cell modules are integrated and sealed in the hollow glass curtain wall. In this sealed state, the heat generated by the solar cell modules during the working process will not be well conducted to the outside of the curtain wall structure. , resulting in a continuous rise in the temperature inside the curtain wall. When the outdoor temperature is 20°C, the internal working temperature of the solar curtain wall can reach a maximum of more than 70°C. When the temperature rises by 1°C, its normal photoelectric ...
