Host apparatus with waterproof function and heat dissipation module thereof

摘要

A heat dissipation module suitable for a host apparatus is provided. The heat dissipation module has a shell body. The shell body has a heat conductive side and an air outlet-inlet side. The air outlet-inlet side has an air outlet and an air inlet. A contact sink having a fixing portion and a contact portion is installed on the heat conductive side such that the contact portion contacts a position requiring heat dissipation in the host apparatus. A heat conductive tube is disposed in the shell body between the fixing portion of the contact sink and the air outlet. A heat dissipation fin is disposed on the air outlet. A waterproof fan is installed on the air outlet. The shell body and the contact sink define an enclosure having waterproof edges except for openings on the air outlet-inlet side.
