Description
Technical Field
[0001] This utility model relates to the field of computer accessories, specifically a chassis frame with good heat dissipation. Background Technology
[0002] Computers are common tools for life and work, providing great convenience to people's work and life. The computer is composed of a case and a monitor, with the case being the most important part. It houses the necessary hardware components such as the motherboard, heat sink, and memory. Computers generate a lot of heat during operation. Usually, when the computer is placed directly on the ground, the heat dissipation effect is poor, especially when it is placed against a wall. When the back of the case is close to the wall or work station partition, the case fan's heat dissipation effect is poor. Utility Model Content
[0003] In view of the problems existing in the prior art, this utility model discloses a chassis frame with good heat dissipation effect. The technical solution adopted includes an open placement box, an electrical interface, an adjustable support, a spacing adjustment mechanism, an L-shaped placement plate, rollers, a bottom fan, a rear slide rail, screw holes, locking screws, a slider, a rear convex plate, a lifting structure, a T-shaped rod, a fixing ring, a backflow bend, and a flared mouth. The electrical interface and adjustable support are provided on the side of the open placement box, which can adjust the height of the open placement box from the ground. The spacing adjustment mechanism is provided on the bottom surface of the open placement box, and the L-shaped placement plate is installed through the spacing adjustment mechanism. The chassis is placed through the L-shaped placement plate, so the adjustment of the spacing of the L-shaped placement plate can adapt to chassis of different widths, making the actual use more flexible. Several rollers are rotatably installed on the inner wall of the vertical part of the L-shaped placement plate. The rollers allow the chassis to be pushed backward directly on the L-shaped placement plate when it is placed, reducing friction and making the placement process more effortless. A through slot is cut into the bottom of the box, through which a bottom fan is mounted via a mounting bracket. This bottom fan is electrically connected to an interface, meaning a standard power line is installed at the bottom of the mounting bracket. This line connects to the interface, with one end of the power line connected to an external power source and the other end plugged into the interface to power the bottom fan. A rear slide is fixed to the rear side of the box, and several through screw holes are cut into the rear wall of the slide. Locking screws are installed by engaging the screw holes, with their ends extending into the slide to tighten the slider. A rear protrusion is fixed to the rear wall of the slide that protrudes above the slide. A lifting mechanism is installed on the rear protrusion, and a T-shaped rod is installed via the lifting mechanism. A fixing ring is fixed to the upper end of the T-shaped rod, and the backflow bend is fixed to the fixing ring. A flared mouth is set at the front end of the backflow bend. By changing the position of the slider and adjusting the lifting mechanism, the flared mouth can be aligned with the exhaust position of the chassis fan, thus reversing the airflow blown out during the heat dissipation process and preventing it from blowing directly onto the rear wall or panel, which would affect the heat dissipation effect.
[0004] As a preferred technical solution of this utility model, the adjustable support includes a side fixing sleeve, a movable column, a top limiting plate, a base, a side groove, a blind hole, a shaft, an end plate, and a spring. The side fixing sleeve is integrally formed on the side of the open box. The outer side of the side fixing sleeve has a through hole. The movable column is movably placed on the side fixing sleeve, and its outer wall contacts the inner wall of the side fixing sleeve. The top and bottom of the movable column are respectively fixed with a top limiting plate and a base. The outer side of the movable column has a side groove, and the bottom surface of the side groove is evenly distributed with blind holes. One end of the shaft passes through the through hole and is inserted into the blind hole to position the movable column. An end plate is fixed to the outer end of the shaft. A spring is connected between the end plate and the outer wall of the side fixing sleeve. The spring is entirely sleeved on the outside of the shaft.
[0005] As a preferred technical solution of this utility model, the bottom surface of the base is provided with anti-slip grooves.
[0006] As a preferred technical solution of this utility model, the spacing adjustment mechanism includes a bottom groove, a bidirectional lead screw, and a knob. The bottom surface of the open placement box has a bottom groove, and the bidirectional lead screw is rotatably installed in the bottom groove. The unthreaded part of the right end of the bidirectional lead screw extends out from the hole through the side of the open placement box, and the knob is fixed at the end of the extended end. The bottom surface of the L-shaped placement plate has an integrally formed protrusion, which fits into the bottom groove. The protrusions on the left and right sides are symmetrically installed on the bidirectional lead screw. The outer wall of the knob has an anti-slip groove. The rotation of the knob drives the bidirectional lead screw to rotate, so that the two L-shaped placement plates approach each other to facilitate the smooth placement of the chassis.
[0007] As a preferred technical solution of this utility model, the lifting structure includes a vertical shaft and a lead screw. The vertical shaft is fixed at both ends on the upper surface of the rear convex plate, and the lead screw is rotatably installed. The T-shaped rod is movably sleeved with the vertical shaft at both ends and is installed in cooperation with the lead screw. A circular plate is fixed on the top of the lead screw.
[0008] The beneficial effects of this utility model are as follows: the adjustable support can adjust the height of the open placement box from the ground, and the spacing between the L-shaped placement plates can be adjusted by the spacing adjustment mechanism, which can adapt to chassis of different widths and make the actual use more flexible. By changing the position of the slider and adjusting the lifting structure, the horn can be aligned with the air outlet of the chassis fan, and the air blown out during the heat dissipation process is reversed to prevent it from blowing towards the rear wall or wall panel and affecting the heat dissipation effect.
