Detailed Description
The electric heating plate is a main component for heating lamination, and is a plate-like structure that can be used for heating an article. Because the electric heating plate is plate-shaped structure, when receiving the extrusion, receive the damage easily, for example, when the electric heating plate is applied to the photovoltaic laminator, because the photovoltaic laminator is under the condition of heating, to each level object pressurization to with each level object heating together, because the electric heating plate also can receive great pressure when hot pressing, the damage appears easily, greatly reduced electric heating plate's life. In addition, because the lamination process has the heating link, the edge heat dissipation of electrical heating board is high, heats unevenly, can lead to the phenomenon that both ends warp, has increased the deformation damage of electrical heating board. The prior art mainly adopts a reinforcing mode. This reinforcement method is equivalent to thickening the electric heating plate, and is capable of protecting the electric heating plate, but does not substantially solve the problem that the electric heating plate is easily damaged when being pressed or heated unevenly.
Therefore, an electric heating plate system, a heating method and a laminating machine for a photovoltaic module are lacked, and the electric heating plate system, the heating method and the laminating machine are used for solving the problem that an electric heating plate is easy to damage when being extruded or heated unevenly in the prior art.
The electric heating plate system is used as an upper box structure of the laminating machine. A typical laminator typically includes an upper tank and a lower tank, where the components to be laminated are placed on the lower tank, and the components are pressurized and heated by the upper tank to encapsulate the layers of the components together. The main body portion of the upper case is generally a rectangular plate. The commonly used photovoltaic modules are battery pieces, EVA, back films and other photovoltaic modules. The embodiment of the invention provides an electric heating plate system for a photovoltaic module, which is applied to a laminating machine. Referring to fig. 1, a schematic diagram of an electric heating plate system for a photovoltaic module according to an embodiment of the present invention is provided.
The electric heating plate system includes: the heat conduction liquid bag 1 is plate-shaped and is provided with a liquid inlet and a liquid outlet, and the heat conduction liquid bag 1 is used for laminating and heating the photovoltaic module; the electric heating plate 5 is arranged on the lower end surface of the heat conduction liquid bag 1, is fixedly connected with the heat conduction liquid bag 1 and is used for heating the heat conduction liquid bag 1; the liquid compensation unit 2 is used for feeding liquid into and discharging liquid from the heat conduction liquid bag 1 through a liquid inlet and a liquid outlet; the hydraulic tester 3 is used for identifying the pressure intensity of the heat conduction liquid bag 1; and the control module 4 is used for controlling liquid inlet and liquid outlet according to the pressure of the heat conduction liquid bag 1 identified by the hydraulic tester 3, and adjusting the hardness of the heat conduction liquid bag 1 by changing the pressure of the heat conduction liquid bag 1.
It should be understood that in the embodiment of the present invention, the plate-shaped heat-conducting liquid bag 1 is disposed on the surface of the electric heating plate 5 for heat lamination of the photovoltaic module, and the upper surface is used for heat lamination of the photovoltaic module instead of the conventional heating plate. In this way, the surface of the heat conduction liquid bag 1 has flexibility and elasticity, preventing long-term damage caused by the electric heating plate 5 and mutual pressing during lamination. The surface of the photovoltaic module can be better attached, and the generation of bubbles is reduced. In addition, an electric heating plate 5 is provided on the lower end face of the heat conduction liquid bag 1 to heat the heat conduction liquid bag 1. When the heat conduction liquid bag is used in heating, the control module 4 can ensure that the heat conduction liquid bag 1 has enough hardness through the pressure intensity of the heat conduction liquid bag 1 identified by the hydraulic tester 3. The control module 4 can control the pressure intensity of the heat conduction liquid bag 1, so that the hardness of the heat conduction liquid bag 1 can be regulated and controlled. When facing different photovoltaic modules, the hardness of the heat conduction liquid bag 1 can be adjusted according to practical conditions. Typically, the laminator heats the photovoltaic module at a temperature of about 140 ℃. The heat conduction liquid bag 1 can be composed of a thickened liquid-resistant nylon rubber layer and a silicon rubber layer, and is connected through waterproof adhesives. The thickness of the heat conducting liquid bag 1 may be 5mm to 20mm in practical application.
Referring to fig. 2, an embodiment of the present invention provides a heating method for a photovoltaic module, including:
s100, the liquid compensation unit 2 performs liquid feeding and liquid discharging in the heat conduction liquid bag 1 through a liquid inlet and a liquid outlet.
S200, the hydraulic pressure tester 3 recognizes the pressure of the heat conduction liquid bag 1.
S300, the control module 4 controls liquid inlet and liquid outlet according to the pressure of the heat conduction liquid bag 1 identified by the hydraulic tester 3, and the hardness of the heat conduction liquid bag 1 is adjusted by changing the pressure of the heat conduction liquid bag 1.
In a preferred embodiment, the laminated heating surface of the heat conducting fluid bag 1 is embedded with matrix metal sheets 11. Referring to fig. 3, a schematic diagram of a heat-conducting liquid bag with a matrix metal sheet is disclosed in an embodiment of the present invention.
It should be appreciated that the metal sheet conducts heat faster, and in order to accelerate the heat transfer rate of the heat conducting fluid bag 1 to the photovoltaic module, a matrix metal sheet 11 is inserted into the laminated heating surface. The metal sheets are arranged in a matrix shape, so that gaps are formed between the metal sheets, bending is facilitated, and the flexibility of the heat conduction liquid bag 1 is improved.
In a preferred embodiment, the number of the heat-conducting liquid bags 1 is plural, the heat-conducting liquid bags 1 are detachable and can be connected in a combined mode, and the liquid inlets and the liquid outlets of the adjacent heat-conducting liquid bags 1 are correspondingly connected.
It should be understood that the heat conducting liquid bags 1 can be directly spliced and combined, and are easy to disassemble, so that the flexibility of using the heat conducting liquid bags 1 is improved. In practical application, the heat conduction liquid bags 1 are combined and spliced into electric heating plates 5 with different areas. In this way, the electric heating plate 5 is ready for use in all laminators. Meanwhile, the heat conduction liquid bag 1 can be replaced simply, and is easy to maintain.
Further, the heat conduction liquid bags 1 are connected through clamping grooves; one of the liquid inlet and the liquid outlet of the heat conduction liquid bag 1 is in a convex shape, the other is in a groove shape, and the convex and the groove are corresponding. In this way, the sealing and clamping of the heat conduction liquid bag 1 are facilitated.
Further, the heat conducting liquid bag 1 comprises a central heat conducting liquid bag 12 and an edge heat conducting liquid bag 13, and the heating plate comprises a central heating plate and an edge heating plate; wherein the central heating plate heats the central heat conducting liquid bag 12 and the edge heating plate heats the edge heat conducting liquid bag 13.
Referring to fig. 4, a schematic combination diagram of a central heat-conducting fluid bag and an edge heat-conducting fluid bag in an embodiment of the present invention is shown. The four heat conducting liquid bags 1 at the outer side are edge heat conducting liquid bags 13, and the four heat conducting liquid bags 1 at the central area are central heat conducting liquid bags 12.
It should be understood that the electric plate cannot achieve uniform heating in temperature control due to slow heat dissipation in the central region and fast heat dissipation in the peripheral region of the electric heating plate 5. Therefore, in order to make the actual temperatures of the central area and the surrounding area of the electric heating plate 5 the same in practical use, the temperatures of the heat transfer liquid in the edge heat transfer liquid bag 13 and the center heat transfer liquid bag 12 are not the same. The edge thermal fluid bag 13 should have a higher thermal fluid temperature than the center thermal fluid bag 12. Therefore, the heat transfer liquid in the edge heat transfer liquid bag 13 and the center heat transfer liquid bag 12 need to be controlled in temperature by the portions of the corresponding two heating plates, i.e., the center heating plate and the edge heating plate, respectively, so that the heating temperatures of the edge heat transfer liquid bag 13 and the center heat transfer liquid bag 12 are the same in practice.
Correspondingly, the liquid compensation unit 2 performs liquid feeding and liquid discharging in the heat conduction liquid bag 1 through a liquid feeding port and a liquid discharging port, and comprises:
the central heating plate controls the liquid temperature of the central heat-conducting liquid bag 12, and the edge heating plate controls the liquid temperature of the edge heat-conducting liquid bag 13, so that the lamination temperature of the central heat-conducting liquid bag 12 and the edge heat-conducting liquid bag 13 is uniform.
In a preferred embodiment, the lamination heating surface of the heat conduction liquid bag 1 is a curved surface and is used for heating and laminating the photovoltaic module with the curved surface.
The embodiment of the invention also discloses a laminating machine, which comprises the electric heating plate system.
In summary, the embodiment of the invention discloses an electric heating plate system for a photovoltaic module, a heating method and a laminating machine, wherein the electric heating plate system comprises a plate-shaped heat conduction liquid bag 1, an electric heating plate 5, a liquid heating system, a hydraulic tester 3 and a control module 4. The heat conduction liquid bag 1 in a plate shape is arranged on the surface of the electric heating plate 5 for heating and laminating the photovoltaic module, and the control module 4 adjusts the hardness of the laminated plate by changing the hydraulic pressure of the heat conduction liquid bag 1. The electric heating plate 5 is also flexible and can be prevented from being damaged due to deformation under the condition of ensuring the hardness of the electric heating plate 5 during operation.
