Description

[0001] The present invention relates to a modular diode heat sink assembly for solar power generation,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diode heat sink assembly for photovoltaic power generation that rectifies and outputs electricity sent from each solar panel in a solar power generator.

The industrial societies are becoming more sophisticated, the population is increasing, and the use of many electrical and mechanical devices that require electricity requires a lot of energy. The most widely used energy sources are fossil energy sources such as coal and petroleum natural gas, and nuclear power generation, which are low in electricity generation cost. These fossil fuel sources are gradually being exhausted due to limited fossil fuel stores. It is important to develop an alternative energy source because it has a great impact on global warming because it emits various kinds of pollution including carbon dioxide. The nuclear power generation which is considered as an alternative of these fossil fuels, As a result, we are looking for alternative energy sources.

On the other hand, unlike fossil energy sources such as coal and petroleum natural gas, solar heat is supplied almost indefinitely at the same time as clean energy without pollution, and it has long been possible to use such solar energy as an energy source for industrial use, heating or automobile And commercialization is being carried out along with steady research.

Currently, solar energy collectors and photovoltaic modules are used as alternative energy sources.

Plate type solar collector and system is a renewable energy system that obtains hot water and heating energy by directly exchanging heat with heat medium by using solar heat energy. It is a renewable energy system widely used because it has high efficiency and high initial investment cost.

Meanwhile, the photovoltaic module and system is a device that generates electric energy by absorbing the light energy of sunlight without environmental pollution and converting it into electric energy by only one installation without needing separate maintenance.

Such a solar device converts light energy, especially solar energy, into electrical energy. The electrical energy generated by the photovoltaic generation is a form of renewable electrical energy that can be used for exactly the same purpose as the electricity generated by the battery or the electricity generated by the established power grid. One type of photovoltaic device is known as a solar module or is referred to as a solar module.

These modules include one or more conventional and preferably a plurality of solar cell panels located between a substrate sheet such as a clear glass or transparent polymer material and a backing sheet such as a polymeric material, a metal sheet or another glass sheet, Respectively. The solar cell can be made of a silicon wafer or other suitable semiconductor material or it can be a thin film cell typically deposited on a substrate or backing sheet in a variety of processes and methods known to those skilled in the art of photovoltaic device manufacture . One type of more conventional type of photovoltaic module includes a plurality of individual solar cells made of silicon wafers. Such solar cells are typically made of either single crystal or polycrystalline wafers and typically these multiple individual cells are electrically linked to the desired arrangement to achieve a module having a desired electrical output upon exposure to the sun.

 In order to obtain a large amount of electricity, a plurality of photovoltaic panels are collectively installed in a large area. The electricity produced by each photovoltaic panel is supplied to the entire system of FIG. 1 and the actual panel of the switchboard of FIG. 2 The fuse holder 11 (corresponding to each solar cell panel 10) is connected to each photovoltaic panel 10 in such a manner that the fuse is disconnected when the current to be transmitted from each photovoltaic panel to each diode is below a predetermined value, A plurality of diodes (13, each diode is provided as a number corresponding to the photovoltaic panel and the fuse holder) provided in a modularized diode heat sink assembly (12) via a connection terminal The electric current is supplied to the AC electric furnace, that is, the bridge having the predetermined Hertz Through the inverter 16 to convert the voltage is a system for supplying Where Used 17, for example, home or factory, or the like Korea Electric Power Corporation.

In order to prevent the diodes 13 from deteriorating because the diodes 13 that rectify electricity generated by the solar cell panel 10 generate a lot of heat during operation, the diode heat sink assembly 12 is preferably made of aluminum or aluminum And the diodes 13 are fixedly mounted on the aluminum heat sink 18.

The heat dissipating plate 18 of the aluminum material is provided with a plurality of heat dissipating fins 19 so that the heat dissipating fins 19 are in contact with the air to dissipate the heat generated in the diode 13 to the outside. In addition to simply dissipating the heat generated from the diode 13, electricity from the solar cell panel 10 is transferred to the respective diodes 13 through the electric wire 20, The electric power rectified in the diode 13 rides on the body of the heat sink 18 in the process of collecting all the electricity and transferring it to the inverter 16 side via the current integrated transmission rod 14 formed immediately after the copper booth The current flows integrally with the current collecting transfer rods 14 connected to the heat radiating plate 18, causing a large loss in the current transfer.

The reason for this is that the heat sink 18 is extruded from an aluminum material to dissipate the heat of the diode 13, and aluminum is an inexpensive conductor that has excellent heat dissipation properties and good electrical conductivity. However, It is relatively bad, and the generated electricity is largely lost in the process of flowing through the heat sink 18 body.

On the other hand, it is general that the diode heat sink assembly 12 is packaged with a fuse holder 11, an overcurrent circuit breaker 15, an inverter and the like, installed in a casing (switchboard), and a packaged casing (switchboard) 3, the diodes 13 are mounted on the front surface of the heat sink 18 so that the heat dissipation fins 19 protruding from the front surface of the heat sink 18 in order to improve heat dissipation can be mounted on the diodes 13 Since the heat radiating fins 19 are in contact with the side of the building wall surface and the rear side is blocked, the flowability of fresh air is deteriorated and the heat radiation cooling ability of the diode 13 is lowered. There has been a problem that the lifetime is lowered.

Another problem is that copper-clad wires 20 are used as members connecting each fuse holder 11 to conduct electricity to the diodes 13, where the copper clad wires 20 are connected to a center- And both ends of a copper wire, which has been stripped off from both sides after being cut to a predetermined length from a long covered wire, is connected to the fuse holder 11 and particularly to the side of the diode 13 The copper-clad wires 20 have a large bending property, and the arrangement of the clad-clad wires 20 is not smooth and the aesthetics are not good, and the wires 20 are arranged in a straight line There is a problem in that a separate tidying member 22 is interposed in the middle for alignment.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a modularized solar cell module capable of reducing the electrical resistance loss of an aluminum heat sink provided to cool a diode, And a diode heat sink assembly for power generation.

Another object of the present invention is to provide a modularized diode heat sink assembly for modularized solar cells, which is capable of improving the heat radiation performance of the heat sink for cooling the heat generated by the diode rectifying the electricity generated by the solar battery panel.

In the present invention, a bus bar plate made of a copper (Cu) plate is attached to a diode mounting face portion of a solar heat releasing diode heat sink assembly formed only from an aluminum material in consideration of heat dissipation only, and the lower ends of the diodes are mounted with a diode Electricity generated by the photovoltaic panel and rectified by the diodes flows through the bus bar plate and is transferred to the inverter side. As a result, compared to the case where electricity is passed through the heat sink, which is an aluminum plate, And the bus bar wire obtained by processing the wire rod obtained by punching the copper plate into a predetermined standard form and the end portion thereof is used to connect each diode and the fuse holder It is very easy to assemble and modularized to be productive. Right it can be obtained a diode heat sink assembly for superior modular solar power.

In addition, since the heat dissipating fins are formed on the back side of the heat dissipating plate in which the diodes are mounted, the heat dissipation performance is poor due to poor ventilation, which shortens the lifetime of the diodes. However, So that the cooling fins are strengthened in contact with the air and the heat dissipation performance is increased.
