<p>PURPOSE:To prevent functional trouble and fusion due to heat without increasing cost or occupying space by suppressing temperature rise through a simple structure of substantially same size as conventional one. CONSTITUTION:In the heat dissipation structure for electric joint box containing an electric circuit, i.e., a heat source, the front cover 31 to be fixed detachably to the opening of the body employs a double structure having inner hollow section 31a. A cooling liquid 35 is encapsulated in the hollow section 31a.</p> |
