Title:
STORAGE DEVICE FOR REFRIGERATOR CONTROL BOARD
Document Type and Number:
Japanese Patent JP2005300092
Kind Code:
A
Abstract:

To provide a storage device for a refrigerator control board that increases the reliability and life of parts of a control board by reducing a temperature rise especially of a power element out of the parts even under thermal effects depending on refrigerator installation conditions and use conditions.

The storage device for a refrigerator control board has a refrigerator back panel 1, a casing 2 fixed to the refrigerator back panel 1, the refrigerator control board 3 with electronic/electric parts mounted on a board circuit fixedly stored in the casing 2, and a lid 4 for protecting the control board 3. The control board 3 is mounted with the power element 5. The power element 5 is fixedly provided with a heat sink 6. The heat sink 6 is provided with an electrically insulating good heat conductor 7. The electrically insulating good heat conductor 7 is butted against the lid 4. Heat generated from the power element 5 is thus transferred direct from the heat sink 6 to the lid 4 via the electrically insulating good heat conductor 7 for heat diffusion and radiation, so that a temperature rise of the power element 5 can be reduced and the reliability and life of the parts are increased.
