Abstract
The present invention discloses a thermal module for light source, which comprises a heat-conducting part and a heat-dissipating part engaged therewith. The heat-conducting part is provided with a heat-receiving portion to receive the heat generated by a light source, a joint portion to join with the heat-dissipating part. The heat-dissipating part is provided with a plurality of fin-shaped heat-dissipating sheets for heat dissipation and to join with the joint portion of the heat-conducting part.
Claims10
A thermal module for light source, comprising:
- a heat-conducting part comprising a heat-receiving portion, to receive heat generated by a light source;
- a joint portion extended out from one side of said heat-receiving portion, and said joint portion comprises a plurality of first engaging slots distributed on outer periphery of said joint portion;
- and
- a heat-dissipating part comprising a plurality of fin-shaped heat-dissipating sheets formed radially extended thereon, and said fin-shaped heat-dissipating sheets comprising a plurality of second engaging slots formed thereon, wherein said second engaging slots are corresponding to said first engaging slots for engaging mutually, fixing said heat-dissipating part on outer periphery of said joint portion, and receiving said heat from said heat-conducting part;
- wherein heat transfer coefficient of said heat-conducting part is higher than heat transfer coefficient of said heat-dissipating part.
