Detailed ways

A preferred embodiment of the electronic component device with an air duct of the present invention will be described below with reference to the accompanying drawings. For ease of understanding, the same components in the following embodiments are described with the same symbols.

Please refer to FIG. 1 , which is a side view cross-sectional structure schematic diagram of a preferred embodiment of the electronic component device with air duct of the present invention. The electronic component device with air duct of the utility model includes: a housing 11 , an air inlet 12 , an air outlet 2 , a plurality of heat source bodies 14 and a plurality of bearing surface bodies 16 . The housing 11 is arranged with a plurality of bearing surfaces 16 that are roughly parallel to each other, so that the housing is formed into a plurality of accommodating spaces 17, and the bearing surfaces 16 are provided with a plurality of heat source bodies 14, and the heat source bodies 14 can be It is an electronic component or a hard disk, and a gap s is formed between the top side of each heat source body 14 and another bearing surface body 16 . Each of the supporting surface bodies 16 further has at least one opening 18, and the opening 18 can make the accommodating space 17 communicate with another accommodating space 17a. In a preferred embodiment of the present utility model, there are three bearing surface bodies 16, 16a, 16b, the first bearing surface body 16 is a main board, so a plurality of electronic components are arranged on it, and the electronic components are placed on After the telecommunications are turned on and used, heat will be generated, and the second and third carrying surface bodies 16a, 16b respectively carry a hard disk, and the hard disk will also generate heat when in use, so in this embodiment, the heat source The bodies 14, 14a are electronic components or hard disks respectively.

And because the opening direction of the air inlet 12 is roughly parallel to the bearing surface body 16, the outside air flows into the housing 11 through the air inlet 12, and the flow of the air is the passage formed by the arrow in the figure. Direction, firstly through the top surface side of the heat source body (electronic component) 14, and when reaching the other side of the casing 11, the gas will enter the other side through the opening 18 through the blocking of the casing 11 itself. Accommodating the space 17a and flowing along the gap s, the gas will simultaneously take away the heat generated on the heat source body (hard disk) 14a and the heat generated on the bottom surface of the bearing surface body 16 . In a preferred embodiment of the present utility model, when the gas flows to one side of the housing 11 (this side is the same side as the air inlet 12 ) in this gap s, it is blocked by the housing 11 itself, so that The gas enters another accommodating space 17b through the opening 18a. The gas passes through the bottom surface of the supporting surface body 16b and the top surface of the heat source body (hard disk) 14b to the air outlet portion 2 at the same time. Therefore, by the design of this air duct, the air outlet 2 can be designed with only a fan body 21 to extract the gas to the outside of the housing 11 to achieve the purpose of heat dissipation, and because the gas flow passes through each heat source body 14 on the top and bottom sides, thereby greatly improving the heat dissipation efficiency.
