Abstract
The invention provides a heat dissipating module configured to dissipate heat of at least one heating element of a projection device. The heat dissipating module includes a first radiator, a second radiator, a pipe, and at least one fan. The second radiator is disposed opposite to the first radiator. The heating element, the first radiator, and the second radiator are connected to each other through the pipe to form a loop. A working fluid is configured to be filled in the pipe, and the working fluid flows through the first radiator after flowing through the second radiator for heat exchange, and the working fluid flowing into the first radiator flows to the heating element for cyclic heat dissipation after heat exchange again through the first radiator. The fan is configured between the first radiator and the second radiator.
