Heat dissipation module and projection apparatus

A heat dissipation module for dissipating heat from a heat source of a projection apparatus, comprising a thermoelectric module, a heat dissipation member, an absorption material, a transmission member, an insulating material, and an electric fan, wherein

• the thermoelectric module is disposed between the heat source and the heat dissipation member and has a cold side and a hot side opposite to each other, where the cold side is for dissipating heat from the heat source, and the hot side contacts with the heat dissipation member,
• the transmission member has a connection end and an evaporation end, wherein the connection end connects with the absorption material, and
• the insulating material covers at least part of the absorption material and encloses at least part of the transmission member,
• the electric fan is arranged between the connection end and the evaporation end of the transmission member, wherein a wind flow of the electric fan blows toward the evaporation end.
