A computer main chassis for a computer that facilitates the installation of a motherboard

Abstract

The present invention discloses a computer main chassis facilitating the installation of a motherboard for a computer, including a main chassis housing. A left wall plate is movably installed on the left side of the main chassis housing, a right wall plate is fixedly installed on the right side of the main chassis housing, and a rear wall plate is fixedly installed at the rear end of the main chassis housing. The present invention relates to the technical field of computer main chassis. For the computer main chassis facilitating the installation of a motherboard for a computer, the air flow rate at the connection between the heat dissipation pipe and the drainage plate is accelerated through the arched air guiding cavity, preventing air and dust from staying at the connection, avoiding dust accumulation inside the arched air guiding cavity, and guiding and evacuating the hot air inside the main chassis housing by using Bernoulli's principle to achieve autonomous heat dissipation of the motherboard. The air inside the heat dissipation pipe is unidirectionally guided to avoid direct contact between dust and the motherboard, achieving a dust-proof effect. Moreover, due to the pulling effect of the traction rope on the rubber piston, the air inside the arched air guiding cavity can be prevented from flowing back into the heat dissipation pipe in the reverse direction, providing an anti-backflow protection for the air.

Description

Technical Field

[0001] The present invention relates to the technical field of computer chassis, and more particularly to a computer chassis for facilitating the installation of a motherboard in a computer. Background Art

[0002] As a part of computer accessories, the main function of the chassis is to place and fix various computer accessories, playing a role of support and protection. In addition, the computer chassis has a certain shielding effect on electromagnetic radiation. Since the chassis cannot quickly improve the overall performance of the computer like accessories such as the CPU, graphics card, and motherboard, it has not been a key consideration in DIY. However, the chassis is not without function. A chassis with a clear and simple internal structure makes the assembly twice the result with half the effort and effectively solves the problem of zero foundation for some beginners in assembling the chassis.

[0003] The existing computer chassis for facilitating the installation of a motherboard in a computer cannot guide and evacuate the hot air inside the main chassis shell to achieve independent heat dissipation of the motherboard, and cannot play a role in protecting against air backflow. Directly using a fan to dissipate heat from the motherboard makes it easy for dust to accumulate on the motherboard, affecting the normal use of the motherboard. Summary of the Invention

Hexagon screws are installed at the four corners of the left side surface of the main board. The main board is installed on the threaded posts on the surface of the right wall board through the cooperation of the hexagon screws and the double-headed lead screws.

[0009] Preferably, ventilation holes are provided on the surface of the rear wall board, and a dust-proof net is installed at the front end of the rear wall board. Among them, adhesive sheets are connected to the four corners of the dust-proof net, and the dust-proof net is adhesively installed at the front end of the rear wall board through the adhesive sheets.

[0010] Preferably, a motor is installed on the left side surface of the flow guiding plate. A fan blade is rotatably installed on the inner side of the flow guiding plate and is associated with the motor. An arched air guiding cavity is provided on the inner side of the flow guiding plate. The fan blade is used to drive the air in the arched air guiding cavity to flow backward.

[0011] Preferably, the front end of the flow guiding plate is arranged to penetrate through the wall board that penetrates through the front end of the main housing. The rear end of the flow guiding plate is arranged to penetrate through the rear wall board. The flow guiding plate is fitted and installed inside the main housing. An outward protruding wall is provided in the middle of the right side surface of the flow guiding plate. The middle of the flow guiding plate is fitted and installed in the circular groove on the surface of the right wall board through the outward protruding wall.

[0012] Preferably, the fitting frame is installed on the front end of the flow guiding plate through the main housing. A bending air groove for tortuously guiding air is provided on the inner side of the first inclined piece. The second inclined piece is arranged obliquely inside the fitting frame. The second inclined piece is used to block dust inside the fitting frame and conduct oblique drainage of air.

[0013] Preferably, a wall ring is fixedly connected to the outer surface of the heat dissipation pipe. A number of small screws are circularly and arrayedly installed on the wall ring. The heat dissipation pipe is installed on the flow guiding plate through the cooperation of the wall ring and the small screws.

[0014] Preferably, one end of the rubber piston is fixedly connected to the inner wall of the heat dissipation pipe.

[0016] The present invention provides a computer main case for a computer that facilitates the installation of a main board. It has the following beneficial effects:

[0017] 1. The computer mainframe case is convenient for installing a motherboard. The special structure of the arched air inlet cavity can speed up the air flow rate at the connection between the heat dissipation pipe and the air guide plate, prevent air and dust from staying at the connection, and avoid dust accumulation inside the arched air inlet cavity. The outer convex wall arranged on the surface of the air guide plate provides a space for the rubber piston to open to the inside of the arched air inlet cavity, thereby providing a stretching space.

[0018] 2. The computer main case is convenient for installing the motherboard. The first bevel plate and the second bevel plate guide the air twice in an oblique manner, so that dust in the air can be blocked and filtered inside the mosaic frame to prevent a large amount of dust from being retained and accumulated on the motherboard. The dust can be blocked on the dust net by sticking a dust net on the front end of the rear wall plate. The air holes on the surface of the rear wall plate cooperate with the dust blocking mechanism to allow two-way air intake at the front and rear ends of the main case. Finally, the heat inside the main case is guided to the outside through the flow control component and the guide plate. While blocking dust, the circulation of air inside the main case is guaranteed, and the best heat dissipation effect of the guide plate on the motherboard is guaranteed.

[0019] 3. The computer has a mainframe case that is convenient for installing a mainboard. The fan blades are driven by a motor to rotate inside the arched air inlet cavity, and air is transported from front to back. The fan blades are connected to the inside of the arched air inlet cavity through a heat dissipation pipe. By using the Bernoulli principle, negative pressure is generated inside the heat dissipation pipe. The negative pressure is used to fully open the rubber piston, guide and evacuate the hot air inside the mainframe case, and realize autonomous heat dissipation of the mainboard.

[0020] 4. The computer mainframe case is convenient for installing the motherboard. The air inside the heat dissipation pipe is guided in one direction to avoid direct contact between dust and the motherboard, thereby achieving a dust-proof effect. The pulling action of the traction rope on the rubber piston can prevent the air inside the arched air induction cavity from flowing back into the heat dissipation pipe, thereby achieving a reverse reflux protection effect on the air.
