## Background
BACKGROUND
1, Technical Field
The present disclosure relates to computers having a heat dissipation system.
2, Description of Related Art
Computers, such as a server, an all-in-one computer, may include a plurality of heat generation elements, such as central processing units (CPU), memories, north and south bridge chips, and metal oxide semiconductor field effect transistors (MOSFET) for assisting the CPUs and the memories, etc. Many MOSFETS are employed in the motherboard and heat generated by the MOSFETS is directly dissipated by the system fans of the computer. However, the heat dissipation of the MOSFETS may be affected by other heat generation elements and becomes ineffective. Therefore, there is room for improvement within the art.

A cover inlet 32 is defined in the shielding cover 30 corresponding to the first inlet 162. A conditioning vent 34 is defined corresponding to the accommodating vent 155. A cover vent 37 and a communicating hole 39 are defined in one side of the shielding cover 30.
In one embodiment, the guiding plate 50 may be L-shaped or U-shaped, and a plate vent 52 is defined in the guiding plate 50.
Referring through FIG. 3 to FIG. 5, in assembly, the motherboard 20, the heat sink 60, the fan 55, the data storage device 70, and the plurality of affiliated elements 75 are positioned on the backplane 80. The heat sink 60 contacts the CPU 22 and the MOSFET 25 through the heat pipe. The shielding cover 30 covers on the motherboard 20 to form a shielding space 200 therebetween. The guiding plate 50 is located on a side of the shielding cover 30. A heat dissipating space 400 is defined by the guiding plate 50 and the shielding cover 30. The fan 55 and the heat sink 60 are located in the dissipating space 400. The enclosure 10 is covered on the backplane 80. An outer space 600 is defined in the enclosure 10 outside of the shielding cover 30 and the guiding plate 50. The data storage device 70 and the plurality of affiliated elements 75 are located in the outer space 600.
The shielding space 200 communicates the first inlet 162. The heat dissipating space 400 communicates with the shielding space 200 through the cover vent 37. The heat dissipating space 400 communicates with the first outlet 152. The shielding space 200 communicates with the accommodating vent 155. The outer space 600 communicates with the second inlet 164. The plate vent 52 communicates with the outer space 600.
