Abstract
A dual CPU and its heat dissipating structure are applied to a heat dissipating module installed on a dual-CPU computer device, and CPUs are arranged alternately with each other on a motherboard, and the heat dissipating modules are installed at positions of the CPUs, such that the alternately arranged heat dissipating modules can prevent interferences by external cold air, and a heat source produced by the CPUs can be conducted and dissipated to the outside to prevent the heat source form remaining at the surrounding of the CPUs and related components installed on the motherboard to achieve an excellent heat dissipating efficiency.
