Description

Video lottery machine

Technical Field

The utility model belongs to the technical field of the video, concretely relates to video lottery machine with heat dissipation wind channel.

Background

The heat dissipation of the terminal case is always a very concerned problem, and the poor heat dissipation not only affects the operation of equipment, but also can cause safety accidents seriously. Research shows that the best scheme for radiating the heat of the terminal cabinet is to reduce the overall temperature of the host by about 3 to 10 degrees.

To this end, we introduce the concept of a duct. In short, the air duct is the moving track of the air in the case. The air duct with reasonable design can rapidly take away the hot air in the case. The formation of the air channel is mainly because the rotation of the fan inside the main case, the hot air in the case is forcibly pumped out, so that negative pressure is generated in the main case, and the cold air outside the case is sucked into the case from the open hole of the case, thereby forming the exchange of air. The air duct is formed by the fan in the main case in a forced way, so the intensity and the track of the air duct can be influenced by the number and the position of the fan in the main case.

We describe the cooling duct in the most common computer system. Such systems typically have only one power fan and thus form a wind tunnel, with some difference in wind tunnel between the power supply for the 8cm fan and the power supply for the 12 cm fan.

Air duct formed by 8cm fan

In this manner, cool air enters the enclosure from below the front panel of the enclosure and is drawn out from behind the power supply. After the cold air enters the chassis, the heat generated by the major heat generating households such as a hard disk, a CPU, a display card and a memory does not actually flow through the chassis, and is generally taken away by two ways: firstly, hot air generated by a display card and a memory enters a main air duct through a vortex at the edge of the main air duct and is discharged out of a mainframe box; and secondly, the hot air generated by the hard disk rises, is accumulated above the case and is discharged out of the case through an auxiliary air duct formed by the vortex at the edge of the main air duct.

The 8cm power supply fan is adopted for heat dissipation, and the defects that hot air cannot be discharged in time and some heat dissipation dead angles exist in the case, such as a display card, a PCI card and the like are overcome.

Air duct formed by two and 12 cm fans

With a 12 cm fan power supply, the fan position is turned over 90 degrees, resulting in a change in the air path. The main air duct passes through the CPU, so that the heat dissipation of the CPU is improved (from some evaluation articles, the temperature of the CPU is reduced by adopting a 12 cm large fan power supply, such as Naja Cold and quiet King), but the hard disk and the memory still cannot be subjected to ideal heat dissipation.

Of course, the purpose of improving the heat dissipation effect can also be achieved by adding a main case fan. For example, a fan is added to a component with poor heat dissipation, the case fan certainly changes the air channel, but after the fan is added, although an auxiliary air channel can be formed, air flow can flow through the vicinity of the CPU and the graphics card to dissipate heat of the two accessories, the situation is 'too late', the case fan is excessively increased, more forced air channels are formed, the air channel forces are partially offset, the heat dissipation effect is influenced, and particularly, holes are excessively formed in the side face of the case.

Therefore, the lottery terminals in the market at present generally cannot achieve the ideal heat dissipation effect.
