Description

Under-screen desktop ITX (internal temperature sensor) case and case assembly

Technical Field

The invention relates to the field of desktop computer design research, in particular to an off-screen desktop ITX chassis and a chassis assembly.

Background

According to the knowledge of the applicant, most of computer cabinets which are put into practice in the market are cabinet-type cabinets, and when the computer cabinets are used, the cabinet is large in size and occupies more space, so that the cabinet is enabled to be independently arranged in space for placement. In addition, the connecting lines are more, wires are longer, so that the lines are alternately wound behind the case after the connection is finished, the case looks messy, and part of space is occupied, so that the space utilization rate is greatly reduced. While some people do not mind this, it is an unfortunate thing for some people who have compulsive disorders and pursue perfection.

Therefore, people improve the technical scheme, and the space utilization rate is improved by reducing the size of the computer main board, the size of the independent display card and the size of the power module to lower the use of the bottom space. Therefore, the ITX main board, the single-fan independent display card or the integrated display card and the 1U mini power supply are designed to reduce the space use, so that the space use is miniature and small, and the space utilization rate is greatly improved.

However, the technical scheme still has the defects that the computer case still needs to be independently provided with a space for placing the case, the power supply module is limited, only 1U power supply can be used, and the power of the 1U power supply is generally smaller. Although part 1u of the power supply will be high power, the heat dissipation noise is also increased, so that the use of the user is affected. The hiding of the connecting wire of the keyboard and the mouse is not processed, so that the space utilization rate and the aesthetic property are affected, and the reason is that the wire lengths of the keyboard and the mouse are uniform lengths reserved by manufacturers and cannot be improved. At the same time, the performance of the computer is also affected somewhat, for example, the use of an integrated display card is not preferable for some people who have working requirements and play games, the use of a single-fan independent display card can be very weak, and the problem of heat dissipation of a small chassis is also a problem.

The search found that while some have proposed small cabinets, these improvements do not solve the bottleneck problem.
