Definitions

  • the invention relates to a junction box for solar modules, which are constructed using inexpensive protection diodes, such as. axial diodes can be constructed with plastic housing, electronic boards and / or other electronic components, and with the same time a good cooling of these components is achieved.
  • inexpensive protection diodes such as.
  • axial diodes can be constructed with plastic housing, electronic boards and / or other electronic components, and with the same time a good cooling of these components is achieved.
  • junction boxes for solar modules are already known from the prior art, with which a good cooling of the electronic components used in the junction boxes (protection diodes) is achieved.
  • junction box for solar modules is shown, in which the electronic components are pressed by pressure elements against the housing or in recesses which correspond to the geometry of the components.
  • electrical insulation is located between the housing and the components an electrical insulation, which preferably consists of thermally conductive silicone rubber.
  • connection box which has a housing which consists of a base body and a housing cover applied thereto. On at least one side wall of the base body at least one receiving chamber is arranged, which protrudes distally from the side wall. In the at least one receiving chamber is at least one sheathed with an insulating electrical component (protective diode), which rests firmly against the inner sides of the receiving chamber and the housing cover.
  • the D are eckel consists of extruded aluminum, has cooling fins and is above the contour of the body over.
  • junction boxes excellent cooling of the protective diodes (or electronic components) is achieved, but they require a relatively high material and manufacturing costs.
  • a major reason for this is that in order to achieve a thermal coupling to the housing of the junction box, only diodes or components can be used, whose housings are made of metal or have a provided for cooling area of metal. In particular, no cost, axial diodes can be used with plastic housing.
  • CN 200910305097 A describes a magnesium-aluminum alloy junction box for a photovoltaic module having a main body inside which a plurality of diodes and terminals are located, and an upper lid.
  • a metal housing is exposed such that an air passage circulating the main body is formed between the metal housing and the main body of the terminal box. It is envisaged that there is an air hole in the metal housing and that the main body of the junction box is provided with a plurality of air outlet holes.
  • the invention has for its object to find a junction box for solar modules, which can be constructed using cost-effective protection diodes, electronic boards and / or other electronic components, and with a nearly equally good cooling of the components is achieved, as in junction boxes, at where the components are thermally coupled to the housing.
  • the starting point is a junction box for solar modules with a metal housing, usually made of aluminum or an aluminum-magnesium alloy, in which there are protective diodes, electronic boards and / or other electronic components which are arranged in the housing so that they account for a large proportion of give off heat generated by them to the air inside the junction box.
  • the electronic components should not have direct thermal contact with the housing.
  • at least a portion of the housing is formed as an air-to-air heat exchanger which allows heat transfer from the air in the housing to the air surrounding the junction box. Due to the at least one heat exchanger, heat generated during operation in the junction box, effectively transported to the outside and discharged to the ambient air.
  • inexpensive protective diodes such as axial diodes with plastic housing, electronic boards or other electronic components without metal surfaces for thermal connection, can be used without having to dispense with a good cooling of these components.
  • the at least one formed in the metal housing air-air heat exchanger is realized by means by which both the inwardly and outwardly facing surface of the housing, in comparison to a corresponding housing with planar shaped housing sides, is increased.
  • cooling fins are formed on the inside and the outside of the housing.
  • other open metal structures for example lamellae, open-pore metal foam which increase the surface area are also conceivable.
  • the number of cooling fins per housing surface and / or the size of the cooling fins of the housing interior facing part differs from the number / size of the outward pointing part. Since the temperature difference between air and cooling fins inside the housing is greater than on the outside, usually the internal cooling fins are made smaller and / or less dense than the outside.
  • the heat transfer eg by using the free thermal convection
  • the inside of the housing and / or outwardly facing part of the at least one air-to-air heat exchanger may be formed so that the number of cooling fins per housing surface and / or the size the cooling fins shows a graduated course.
  • a Ternninalblock of an electrically insulating material, usually plastic is provided which is provided with receptacles for the components.
  • the terminal block is covered by the metal housing.
  • the terminal block is either provided with a cap made of plastic or it is a sufficient distance between the terminal block and metal housing complied with (insulation by means of air layer).
  • Fig. 1 an opened junction box for solar modules
  • Fig. 2 a junction box with a closed lid.
  • the junction box for solar modules consists essentially of the aluminum housing 1, on the two side parts outside 2.1 and 2.2 internal cooling fins are formed, and the terminal block 3 with recordings 4, by means of which the three axial protection diodes 5 on the terminal block 3 are fixed and electrically integrated into the photovoltaic system.
  • the cooling fins 2.1, 2.2 each cover more than 50% of the area of the two side parts.
  • an air-to-air heat exchanger is formed in each case by the outer 2.1 and inner 2.2 cooling fins thermally connected via the housing wall 6.
  • the housing cover 7 is closed (FIG. 2).
  • the axial protection diodes 5 give the heat generated by them to the air inside the junction box, the internal cooling fins 2.2 absorb the heat from the air, the heat is transported through the housing wall 6 to the outer cooling fins 2.1, which in turn the heat to the ambient air.

Abstract

L'invention concerne une boîte de connexion pour modules solaires, pouvant être conçue à l'aide de diodes de protection, par exemple des diodes axiales dotées de boîtiers plastiques, de cartes électroniques et/ou autres composants électroniques économiques, et permettant d'obtenir simultanément un bon refroidissement des composants électroniques. La boîte de connexion présente un boîtier métallique (1) qui renferme les diodes de protection (5), les cartes électroniques et/ou autres composants électroniques, lesquels sont disposés de manière à céder une grande partie de la chaleur émanant de leur fonctionnement à l'air situé à l'intérieur de la boîte de raccordement. Au moins une zone du boîtier, cette zone étant dotée, par exemple, d'ailettes de refroidissement situées à l'intérieur (2.2) et à l'extérieur (2.1), est conçue comme échangeur thermique air-air et permet un transfert de la chaleur de l'air contenu dans le boîtier à l'air à l'air environnant la boîte de raccordement.
