<p>The present invention relates to a housing module capable of simplifying the structure, reducing manufacturing costs, and improving a heat radiation effect, and to an air cooled type heat sink motor having the same. The housing module includes a cylindrical housing (112) and a heat radiation part (114) which is made of a foaming agent, has a cylindrical shape for radiating heat transmitted through the housing (112) to the outside, and is attached to the outer wall of the housing (112). According to the present invention, the structure of the housing module is simplified by integrating the housing with the heat radiation part made of the foaming agent. Also, manufacturing costs can be reduced by facilitating assembly. The contact area with air can be extended because the heat radiation part is made of the foaming agent. Therefore, a heat radiation effect can be improved.</p> |
