Description

一种太阳电池组件用接线盒及具有此接线盒的组件 技术领域 本实用新型涉及一种太阳电池组件用接线盒， 尤其涉及一种散热性较好 的接线盒及具有此接线盒的太阳电池组件。 背景技术 现有的太阳电池组件用接线盒是采用旁路二极管直接安装于该接线盒内 部的方式。 即所述旁路二极管直接安装在该接线盒内部的导电片上或者接线 座上， 导电片或接线座直接接触的是导热性不良的介质。 为了使所述旁路二 极管散热， 现有技术中有的采用在该接线盒内直接增加散热器。  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a junction box for a solar cell module, and more particularly to a junction box having better heat dissipation and a solar cell module having the junction box . Background Art A conventional junction box for a solar cell module is a method in which a bypass diode is directly mounted inside the junction box. That is, the bypass diode is directly mounted on the conductive sheet inside the junction box or on the terminal block, and the conductive sheet or the terminal block directly contacts the medium with poor thermal conductivity. In order to dissipate the bypass diode, some of the prior art uses a heat sink directly in the junction box.
发明人在实现本实用新型的过程中， 发现现有技术中的接线盒存在散热 性不好的问题。 由于与旁路二极管相接触的都是热导性不良的介质， 所以旁 路二极管工作时产生的热量很难散出， 这样会导致旁路二极管的结点温度过 高， 从而会缩短旁路二极管的使用寿命、 增加旁路二极管失效的可能性， 同 时也可能会使该接线盒和太阳电池组件或整个太阳电池组件系统损坏。 通过 在接线盒内直接增加散热器的方式使得旁路二极管散发的热量仍不能传到接 线盒外， 所以散热效果有限， 当旁路二极管长时间工作时仍会有使旁路二极 管失效的可能性， 同时还增加了该接线盒的成本。 实用新型内容 本实用新型的一目的在于， 提供一种太阳电池组件用接线盒， 用以解决 现有接线盒存在散热性不好的问题。  In the process of realizing the present invention, the inventors found that the junction box of the prior art has a problem of poor heat dissipation. Since the contact with the bypass diode is a poorly thermally conductive medium, the heat generated by the bypass diode is hard to be dissipated, which causes the junction diode temperature to be too high, which shortens the bypass diode. The service life, increased possibility of bypass diode failure, and may also damage the junction box and solar module or the entire solar module system. By directly adding a heat sink in the junction box, the heat dissipated by the bypass diode can still not be transmitted outside the junction box, so the heat dissipation effect is limited, and there is still the possibility of invalidating the bypass diode when the bypass diode is operated for a long time. At the same time, the cost of the junction box is also increased.
