  • Patent number: 11777444
    Abstract: An apparatus of a junction box component housed in a junction box and designed to be coupled to a power generator. The junction box component may include one or more bypass mechanisms configured to bypass one or more substrings of the power generator in a case of malfunction or mismatch between the substring and the remainder of the power generators. The one or more bypass mechanisms may generate heat which may be transferred out of the junction box. The junction box component may be designed to conduct the heat towards the base of the junction box and/or the cover of the junction box. A heat dissipation mechanism may be mounted on the base and/or the cover. A bypass mechanism may bypass the entire power generator.

  • Publication number: 20140190738
    Abstract: An electronic substrate 100D has a tabular base material 110 which can install a heater element 120 and the cooling structure that cools the heater element 120. An electronic substrate 100 can be plugged in/out in the case 200 in the direction which is almost parallel to the face of the base material 110. The cooling structure is installed on the tabular base material 110, and has the first heat radiation part 160D with a hollow shape and the heat transfer part 700. The first heat radiation part 160D with a hollow shape radiates the generated heat of the heater element 120 installed in the base material.

  • Patent number: 8773858
    Abstract: The invention relates to heat dissipation means for use with electrical and/or electronic apparatus to provide for the improved cooling of at least one component within the housing of the apparatus. The heat dissipation means includes a first portion located internally of the housing at or adjacent to the at least one component to be cooled and the means is formed of a material to allow the same to be passed via the first portion to an interface and onto a second portion located externally of the housing to allow the heat to be dissipated therefrom to the external environment more effectively. This allows heat to be dissipated without the need for moving heat dissipation means to be provided and avoids the noise and/or vibration which can be created.
