[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-4 A thermally insulated photovoltaic curtain wall with a small frame includes a curtain wall keel, a curtain wall frame 1 and a photovoltaic panel 2 installed on the curtain wall frame 1, and a large number of curtain wall frames 1 are spliced ​​into a curtain wall, and a connecting sealing strip 3 is arranged at the splicing of the curtain wall frame 1. The curtain wall frame 1 includes a supporting inner frame 101, and a plurality of connecting supporting plates 102 are horizontally installed between the supporting inner frames 101. A connecting skirt 103 is installed on the outer surface of the supporting inner frame 101, and the connecting skirt 103 is installed on the curtain wall keel;

[0029] A wiring heat conduction groove 104 is left between the supporting inner frame 101 and the connecting skirt 103 to form a heat-insulating groove and a wiring groove. A wiring hole 105 is opened on the inner wall of the supporting inner frame 101, and an intercommunication groove 106 is opened on the wall surface of the connecting skirt 103. The wiring hole 105 and the intercommunication groove 106 are both used for wiring.

[0030] The photovoltaic panel 2 covers the outer surface of the connecting support plate 102 and is connected by bolts;

[0031] The connection sealing strip 3 covers between the two groups of supporting inner frames 101 to seal the connection seams of the supporting inner frames 101 .

[0032] Through the above technical solution, a connecting skirt 103 is provided on the outer surface of the supporting inner frame 101, so that a wiring heat-conducting groove 104 is formed between the supporting inner frame 101 and the connecting skirt 103, so that wiring can be laid in the wiring heat-conducting groove 104, and the wiring heat-conducting groove 104 is used to reduce the conduction of heat and achieve the effect of heat insulation, and a gap is left between the back side of the photovoltaic panel 2 and the back side of the supporting inner frame 101 to achieve heat dissipation, thereby achieving the effects of facilitating wiring, isolating heat and improving heat dissipation.

[0033] Specifically, the connecting support plate 102 is a T-shaped metal bracket, and the top of the connecting support plate 102 can be penetrated by bolts to fix the photovoltaic panel 2.

[0034] Through the above technical solution, the connecting support plate 102 is set as a T-shaped metal frame, so that the thickness of both sides of the front of the connecting support plate 102 is reduced, so as to facilitate the bolts to penetrate both sides of the front of the connecting support plate 102, thereby facilitating the connection and installation of the photovoltaic panel 2.

[0035] Specifically, the connecting skirt 103 is in a U-shape that opens outward, and the front width of the connecting skirt 103 is smaller than the back width.

[0036] Through the above technical solution, the connecting skirt 103 is set to be U-shaped, so that the front of the connecting skirt 103 can support the back of the connecting sealing strip 3, and the back of the connecting skirt 103 can be installed on the curtain wall keel by bolts. A groove is formed in the middle of the Qien connecting skirt 103, and the groove is used to limit the connecting sealing strip 3 and increase the distance between the two sets of connecting skirts 103, thereby improving the heat insulation effect;

[0037] The overall width of the connecting skirt 103 can be reduced as needed. After reducing the width of the connecting skirt 103 , the width of the connecting sealing strip 3 also needs to be reduced relatively, thereby forming a small frame to reduce the spacing between the photovoltaic panels 2 .

[0038] Specifically, the back side of the supporting inner frame 101 is level with the back side of the connecting skirt 103 , and the back side of the connecting skirt 103 is penetrated by bolts on the curtain wall keel.

[0039] Through the above technical solution, the back side of the supporting inner frame 101 is level with the back side of the connecting skirt 103, so that the entire frame can be easily installed on the curtain wall keel, and the entire surface can be kept horizontal and vertical after installation.

[0040] Specifically, a gap is left between the back side of the photovoltaic panel 2 and the back side of the supporting inner frame 101 , and the circuits of the photovoltaic panel 2 pass through the wiring holes 105 and converge inside the wiring heat conduction groove 104 .

[0041] Through the above technical solution, the back side of the installed photovoltaic panel 2 is supported by the connecting support plate 102, so that a gap is formed between the back side of the photovoltaic panel 2 and the back side of the supporting inner frame 101. These gaps are used to improve the heat dissipation of the photovoltaic panel 2 and facilitate the wiring of the photovoltaic panel 2. The lines are gathered in the wiring heat conducting groove 104 through the wiring holes 105, so that the surface lines are completely on the back side of the photovoltaic panel 2, making it difficult to maintain and repair the lines later.

[0042] Specifically, the photovoltaic panel 2 is entirely covered on the inside of the supporting inner frame 101 or is individually spliced ​​on the inside of the supporting inner frame 101 , and the front side of the photovoltaic panel 2 is higher than the front side of the supporting inner frame 101 .

[0043] Through the above technical solution, the use of a whole photovoltaic panel 2 can reduce the wiring time during installation. If a photovoltaic curtain wall is formed by splicing single photovoltaic panels 2, the single photovoltaic panels 2 can be disassembled and maintained during maintenance, thereby improving the convenience of maintenance.

[0044] Specifically, the connection sealing strip 3 is a T-shaped rubber strip, and the connection sealing strip 3 is covered on the side seam of the supporting inner frame 101 by sealant, and the front side of the connection sealing strip 3 is level with the front side of the photovoltaic panel 2 .

[0045] Through the above technical solution, the connecting sealing strip 3 is set as a T-shaped rubber strip, and the two wings on the front side are used to overlap the photovoltaic panels 2 on both sides, so as to achieve sealing and waterproofing of the wiring heat conduction groove 104. The rubber material has poor thermal conductivity and can effectively achieve the effect of heat insulation.

[0046] When in use, a connecting skirt 103 is provided on the outer surface of the supporting inner frame 101, so that a wiring heat-conducting groove 104 is formed between the supporting inner frame 101 and the connecting skirt 103, so that wiring can be laid in the wiring heat-conducting groove 104, and the wiring heat-conducting groove 104 is used to reduce the conduction of heat to achieve the effect of heat insulation, and a gap is left between the back of the photovoltaic panel 2 and the back of the supporting inner frame 101 to achieve heat dissipation, thereby achieving the effects of convenient wiring, heat insulation and improved heat dissipation;

[0047] By setting a connection sealing strip 3 to cover the connection between multiple supporting inner frames 101, and covering the wiring heat conduction groove 104 with the two wings of the T-shaped connection sealing strip 3, the line is sealed. The rubber connection sealing strip 3 can effectively block heat conduction, and the connection sealing strip 3 is connected by sealant. The connection sealing strip 3 can be easily removed to maintain the line, thereby achieving the effect of further insulation, waterproofing and easy maintenance of the line.
