[0029] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example 1

[0030] Reference Figure 1-Figure 7 , which is the first embodiment of the present invention, provides a temperature control and heat dissipation device for a photovoltaic panel, which includes: a photovoltaic panel assembly 100, a heat dissipation assembly 200 and a protection assembly 300. The photovoltaic panel assembly 100 is a power distribution cabinet in the prior art, and the heat dissipation assembly 200 is provided to facilitate the installation of the heat dissipation terminal, and the protection assembly 300 is provided to provide protection when the heat dissipation terminal is inspected and repaired.

[0031] Specifically, the photovoltaic panel assembly 100 includes a photovoltaic panel body 101, a bracket 102 hinged on one side of the photovoltaic panel body 101, an electrical instrument 103 arranged in the photovoltaic panel body 101, and a switch component 104 installed in the photovoltaic panel body 101, the switch component 104 includes a switching switch, a push button switch, a circuit breaker, an indicator light, etc., which are used to achieve manual control or automatic short circuit, and the electrical instrument 103 includes an ammeter, a voltmeter, a power meter, etc., which are used to display electrical parameters; the heat dissipation component 200, the heat dissipation component 200 is arranged inside the photovoltaic panel body 101, including at least two groups of heat dissipation terminals 201 arranged side by side installed in the photovoltaic panel body 101, and the heat dissipation terminals 201 are connected between the electrical instrument 103 and the switch component 104 through wires.

[0032] Furthermore, the protection assembly 300 is arranged on one side of the photovoltaic panel body 101, and includes a protection plate 301 arranged on one side of the photovoltaic panel body 101, a maintenance slot 302 which is provided through one side of the protection plate 301 and adapted to the heat dissipation terminal 201, and a maintenance plate 303 which is detachably connected to one side of the maintenance slot 302. Each group of maintenance plates 303 is clamped on the maintenance slot 302 for protection, and when maintenance work is required, the group of maintenance plates 303 is disassembled from the maintenance slot 302, so that the maintenance slot 302 is opened for maintenance work, so that the adjacent heat dissipation terminals 201 can be blocked and protected while the group of heat dissipation terminals 201 are being maintained.

[0033] The heat dissipation assembly 200 further includes a mounting rail 202 mounted on the back of the photovoltaic panel body 101, and the heat dissipation terminal 201 includes a heat dissipation tower 201a embedded in one side of the mounting rail 202. The heat dissipation tower 201a is detachable and divided into a first heat dissipation plate 201a-1 slidably connected to the mounting rail 202 and a second heat dissipation plate 201a-2 embedded in one side of the first heat dissipation plate 201a. The heat dissipation tower 201a is provided with first heat transfer grooves 201a-3 adapted to the electrical instrument 103 and the switch component 104 on both sides. When installing the heat dissipation terminal 201, first fix the mounting rail 202 and the inner wall of the photovoltaic panel body 101 through a limit rod, and then clamp one side of the first heat dissipation plate 201a-1 of the heat dissipation terminal 201 on the mounting rail 202. The heat dissipation terminal 201 can be installed from the middle of the mounting rail 202 and slid to both sides along the mounting rail 202 to adjust the position.

[0034] Preferably, a heat conductive sheet 201a-4 adapted to the first heat transfer groove 201a-3 is provided between the first heat dissipation plate 201a-1 and the second heat dissipation plate 201a-2, and a limiting member is provided on one side of the second heat dissipation plate 201a-2 for squeezing the heat conductive sheet 201a-4 toward the first heat transfer groove 201a-3; the limiting member is the prior art of the heat dissipation terminal 201, and the limiting member structures of different types of heat dissipation terminals 201 are not exactly the same, but the functions are the same, usually an elastic buckle, and in this embodiment, it is a pressing structure connecting the clearance shaft and the torsion spring, and the wires on one side of the electrical instrument 103 and the switch component 104 are respectively inserted into the first heat transfer groove 201a-3 on both sides of the heat dissipation terminal 201, and then the heat conductive sheet 201a-4 is squeezed by the limiting member 201a-5, so that the wires on both sides are squeezed and connected by the heat conductive sheet 201a-4.

[0035] The first heat sink 201a-1 is connected to the heat conducting sheet 201a-4 and the second heat sink 201a-2 via a limiting rod 201a-6.

[0036] Furthermore, it also includes a control component 203, which is used to control the connection between the first heat dissipation plate 201a-1 and the second heat dissipation plate 201a-2 in the heat dissipation terminal 201.

[0037] Specifically, a number of heat dissipation terminals 201 are divided into two groups and are respectively arranged on the upper and lower halves of the photovoltaic panel body 101. When observed from the back of the photovoltaic panel, the two groups of heat dissipation terminals 201 are arranged parallel to each other, each heat dissipation terminal 201 is arranged in close contact with the photovoltaic panel body 101, and there is a certain distance between each heat dissipation terminal 201 in each group. By leaving a distance, the heat dissipated from the heat dissipation terminal 201 can come into contact with the outside air, thereby ensuring the stability of heat dissipation.

[0038] Furthermore, the heat dissipation assembly 200 also includes a control component 203 arranged on one side of the photovoltaic panel body 101, and the control component 203 is used to control the contact and separation between the first heat dissipation plate 201a-1 and the second heat dissipation plate 201a-2 in each heat dissipation terminal 201. When the temperature of the photovoltaic panel does not exceed the threshold, the control component 203 will maintain the separation between the first heat dissipation plate 201a-1 and the second heat dissipation plate 201a-2. At this time, only the first heat dissipation plate 201a-1 is in contact with the photovoltaic panel body 101. At this time, only the first heat dissipation plate 201a-1 is used for heat dissipation. When the temperature of the photovoltaic panel exceeds the threshold or is too high, the control component 203 connects the first heat dissipation plate 201a-1 and the second heat dissipation plate 201a-2. At this time, heat can be transferred from the first heat dissipation plate 201a-1 to the second heat dissipation plate 201a-2, which is equivalent to increasing the area of ​​heat flow, thereby enhancing the heat dissipation capacity.

[0039] In this embodiment, the control component 203 includes a rotating disk 203a rotatably connected to the back side of the photovoltaic panel body 101, a first rotating gear 203b arranged on the rotating disk 203a, a first rack 203c meshed with the first rotating gear 203b, and a plug-in board 203d connected to the first rack 203c, and two first racks 203c are provided, both of which are meshed with the first rotating gear 203b, and a plurality of plug-in strips 203e are provided on the plug-in board 203d.

[0040] The rotating disk 203a is arranged between the two groups of first heat dissipation plates 201a-1, and the length direction of the plug-in board 203d is the horizontal extension direction of the first heat dissipation plate 201a-1, and the angle between the connection between the first rack 203c and the plug-in board 203d is 90°, so that the meshing position of the two first racks 203c is longitudinally arranged, and then when the first transmission gear rotates, it will drive the two first racks 203c to slide, so that the two plug-in boards 203d slide away from or close to each other, and then control whether the plug-in strip 203e is inserted into the first heat transfer groove 201a-3. When the plug-in strip 203e is inserted into the first heat transfer groove 201a-3, because the inner diameter of the first heat transfer groove 201a-3 is smaller than the outer diameter of the plug-in strip 203e, the plug-in strip 203e will open the first heat transfer groove 201a-3, thereby realizing the separation of the first heat dissipation plate 201a-1 and the second heat dissipation plate 201a-2.

[0041] Furthermore, the first heat dissipation plate 201a-1 includes a first frame 400, a thermal insulation cavity 401 connected to the first frame 400, and a second frame 402 connected to the first thermal insulation plate. The thermal insulation cavity 401 includes a first inclined plate 401a connected to the first frame 400, a first bent plate 401b connected to the first inclined plate 401a, and a second bent plate 401c connected to the first bent plate 401b. A hinge is provided at the connection between the first bent plate 401b and the second bent plate 401c.

[0042] In this embodiment, the second frame 402 includes a third bent plate 402a, a first buckle 402b arranged on the third bent plate 402a, a second buckle 402c arranged on the second frame 402, a protruding block 402d is provided on the first bent plate 401b, and a mating buckle is provided on the protruding block 402d, which respectively cooperates with the first buckle 402b and the second buckle 402c.

[0043] Preferably, a first extension piece is provided on the first clamping edge 403, and a matching sliding groove matching with the first extension piece is provided on the matching opening.

[0044] Preferably, a first spring is provided between the first heat sink 201a-1 and the photovoltaic panel body 101, and a second spring is provided between the first heat sink 201a-1 and the second heat sink 201a-2. The second spring will always pull the first heat sink 201a-1 and the second heat sink 201a-2 towards each other.

[0045] Operation process: When installing the heat dissipation terminal 201, first fix the installation slide rail 202 to the inner wall of the photovoltaic panel body 101 with bolts, then hang one side of the first heat dissipation plate 201a-1 of the heat dissipation terminal 201 on the installation slide rail 202, and then connect the wires on one side of the electrical instrument 103 and the switch component 104 to the heat dissipation terminal 201, and then connect the first heat dissipation plate 201a-1 and the second heat dissipation plate 201a-2 through the limit rod 201a-6, and repeat the above steps until each group of heat dissipation terminals 201 are installed.

[0046] When the first transmission gear rotates, it will drive the two first racks 203c to slide, so that the two plug-in plates 203d slide away from or towards each other, thereby controlling whether the plug-in strip 203e is inserted into the first heat transfer groove 201a-3. When the plug-in strip 203e is inserted into the first heat transfer groove 201a-3, because the inner diameter of the first heat transfer groove 201a-3 is smaller than the outer diameter of the plug-in strip 203e, the plug-in strip 203e will open the first heat transfer groove 201a-3, thereby realizing the separation of the first heat dissipation plate 201a-1 and the second heat dissipation plate 201a-2. When the photovoltaic panel temperature When the temperature does not exceed the threshold, the control component 203 will keep the first heat sink 201a-1 and the second heat sink 201a-2 separated. At this time, only the first heat sink 201a-1 is in contact with the photovoltaic panel body 101, and only the first heat sink 201a-1 is used for heat dissipation. When the temperature of the photovoltaic panel exceeds the threshold or is too high, the control component 203 will connect the first heat sink 201a-1 and the second heat sink 201a-2. At this time, heat can be transferred from the first heat sink 201a-1 to the second heat sink 201a-2, which is equivalent to increasing the area of ​​heat flow, thereby enhancing the heat dissipation capacity.

[0047] When the connector strip 203e is inserted into the first heat transfer groove 201a-3, it will push the first heat sink 201a-1 outward and towards the photovoltaic panel body 101 at the same time. When the first heat sink 201a-1 is pushed, the first frame 400 and the second frame 402 will be snapped onto the thermal conductive card slot 404, and then the first buckle 402b, the second buckle 402c and the matching buckle will cooperate with the card edge 403 on the thermal conductive card slot 404, so that the first frame 400 and the second frame 402 will be blocked by the thermal conductive card slot 404 and will undergo a certain deformation, thereby forming another cavity structure composed of the second frame 402 and the second bending plate 401c. This structure can further isolate the external heat, thereby forming a temperature insulation structure to prevent the external heat from interfering with the photovoltaic panel.
