Video lottery ticket machine

Abstract

The invention discloses a video lottery ticket machine which comprises a cabinet, and heat dissipation holes are formed in the back surface and two sides of the cabinet to form an upper air duct and alower air duct; an ATX power supply of the main controller is connected with two paths of direct-current fans, one path of fan is located at the position, opposite to the UPS power supply, of the inner wall of the back face of the cabinet, and the other path of fan is located near the ATX power supply of the main controller and corresponds to the upper air duct and the lower air duct respectively. Due to the fact that the two paths of direct-current fans are adopted and matched with the heat dissipation holes of the cabinet shell to form the upper air channel and the lower air channel, sufficient heat dissipation of all parts is achieved, and cost is saved. Therefore, the technical problems that an existing video lottery ticket machine is unreasonable in air duct design, and the number offans and reasonable configuration of heat dissipation holes cannot be considered at the same time are solved, and the ideal heat dissipation effect is achieved.

Description

technical field [0001] The invention belongs to the field of video technology, and in particular relates to a video lottery ticket machine with a cooling air duct. Background technique [0002] The heat dissipation of the terminal chassis has always been a matter of great concern. Poor heat dissipation not only affects the operation of the equipment, but also causes serious safety accidents. Studies have shown that the best way to dissipate heat from the terminal chassis is to lower the overall temperature of the host by about 3 to 10 degrees. [0003] To this end, we have to introduce the concept of air duct. To put it simply, the air duct is the trajectory of air movement in the chassis. Reasonably designed air duct can quickly take away the hot air in the chassis. The formation of the air duct is mainly due to the rotation of the fan inside the main chassis, which forcibly draws out the hot air in the chassis, generates negative pressure in the main chassis, and attrac...

AI Technical Summary

Problems solved by technology

For example, adding a fan to a component with unsatisfactory heat dissipation will definitely change the air duct, but after adding the fan, although an auxiliary air duct can be formed, the airflow can flow near the CPU and graphics card to dissipate heat from these two accessories, but " Too much is not enough", if the chassis fan is increased too much, more forced air ducts will be formed, and the air duct forces will partially offset each other, which will affect the heat dissipation effect, especially if there are too many holes on the side of the chassis

[0011] It can be seen that the current lottery terminals on the market generally cannot achieve the ideal heat dissipation effect
