Technical Field

[0001] This utility model relates to the field of chassis heat dissipation technology, and in particular to a chassis equipment shell heat dissipation hole layout structure with bottom air intake. Background Technology

[0002] The purpose of chassis cooling is to quickly expel the heat generated by the hardware outside the chassis and continuously draw in cool air, thereby ensuring stable computer operation, full performance, and extending the life of the hardware.

[0003] After prolonged use, dust buildup on the filters of existing computer cases can reduce their cooling efficiency, leading to reduced performance of internal components and poor heat dissipation.

[0004] To address this, a bottom-intake chassis and equipment enclosure heat dissipation hole layout structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a bottom-intake chassis equipment shell heat dissipation hole layout structure to solve the problem mentioned in the background art that after long-term use, the existing chassis heat dissipation will have a reduced heat dissipation effect due to dust clogging the filter screen, resulting in poor performance of the components inside the chassis and poor heat dissipation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bottom-intake chassis equipment shell heat dissipation hole layout structure, including a chassis, wherein a first air intake plate and a second air intake plate are provided at the bottom of the chassis, a fan is installed at the rear end of the chassis, the first air intake plate and the second air intake plate are stepped, the first air intake plate is at the top, a baffle is provided at the upper end of the second air intake plate, an air intake device is provided above the baffle, a mounting plate is provided at the bottom of the chassis, and a filter screen is provided in the middle of the mounting plate.

[0007] Preferably, the air inlet device includes a flip cover, a connecting rod is fixedly installed on the upper wall of the flip cover, a bearing is installed at the other end of the connecting rod, a mounting seat is installed on the outer wall of the bearing, the mounting seat is fixedly installed on the baffle, a horizontal plate is installed at the top of the mounting seat, a bracket is installed at the bottom of the other end of the horizontal plate, the bracket is fixedly installed on the baffle, and a first spring is installed above the flip cover, with the other end of the first spring connected to the lower wall of the horizontal plate.

[0008] Preferably, the bottom of the chassis is provided with a mounting block, which is located below the fan. The mounting block has an opening inside, and a locking block is slidably disposed in the opening. A second spring is provided on the upper wall of the locking block. A mounting cover is provided on the top of the opening. The other end of the second spring is connected to the mounting cover. A slot is provided on the mounting plate, and the slot cooperates with the locking block.

[0009] Preferably, the baffle is provided with a plurality of through holes evenly distributed, and the air inlet device is provided with a plurality of them, with each air inlet device cooperating with one of the through holes.

[0010] Preferably, a sealing gasket is provided on the lower wall of the flip cover, and the flip cover mates with the through hole.

[0011] Preferably, the locking block, the second spring, the mounting cover, and the locking groove are symmetrically arranged in two sets. A limit rod is provided on the side wall of the mounting plate, and a limit groove is opened at the bottom of the chassis. The limit rod cooperates with the limit groove.

[0012] Preferably, one half of the card block is set as an inverted trapezoid, and generally it is set as a square, wherein the square is slightly longer than the inverted trapezoid.

[0013] Preferably, the lower end of the outer wall of the mounting block is provided with a bevel.

[0014] The beneficial effects of this utility model are: This utility model features a stepped design with two air intake plates. A baffle and air intake device are installed on the bottom second air intake plate, flush with the first air intake plate, thus not obstructing the installation of internal components. A filter at the bottom filters dust from the air, ensuring clean air entering through the intake plates and reducing the impact of dust on internal components. Over time, dust accumulates on the filter, reducing airflow and thus weakening heat dissipation. Due to the increased dust and poor ventilation, a negative pressure is created inside the chassis by the fan. External atmospheric pressure forces open the air intake device, allowing air to enter through the other half of the intake and the filter, thus cooling the chassis.

[0015] This utility model uses a second spring, a locking block, and a locking groove to quickly fix the mounting plate and filter screen, and facilitates disassembly, cleaning, and replacement. The air inlet device opens the flip cover when negative pressure is applied inside the casing and closes it when normal air pressure is restored. When the flip cover closes, it exerts an impact force on the second air inlet plate and the filter screen, which has a certain cleaning effect on the filter screen. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0020] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0021] like Figures 1 to 5As shown in the figure, a specific embodiment of this utility model provides a bottom-intake air intake chassis equipment shell heat dissipation hole layout structure, including a chassis 1. The bottom of the chassis 1 is provided with a first air intake plate 3 and a second air intake plate 12. A fan 2 is installed on the rear end of the chassis 1. The first air intake plate 3 and the second air intake plate 12 are stepped, with the first air intake plate 3 on top. The upper end of the second air intake plate 12 is provided with a baffle 10. An air intake device 4 is provided above the baffle 10. A mounting plate 6 is provided at the bottom of the chassis 1, and a filter screen 5 is provided in the middle of the mounting plate 6.

[0022] By adopting the above technical solution, this utility model uses a fan 2 to dissipate heat inside the chassis 1. The operation of the fan 2 drives the airflow inside the chassis 1, reducing the air pressure inside the chassis 1. Under the action of air pressure, the external air passes through the filter screen 5 to filter dust and then enters the chassis 1 through the first air intake plate 3, forming an air circulation that carries away the heat from the components of the chassis 1 for heat dissipation. Over time, dust will accumulate on the filter screen 5, reducing its ventilation and affecting the air circulation effect. At the same time, because the ventilation of the filter screen 5 has decreased, the air inside the chassis 1 flows out under the action of the fan 2, but the external air cannot enter the chassis 1 well, creating a negative pressure inside the chassis 1. Subsequently, under the influence of air pressure, the air intake device 4 is opened, and the air can enter the chassis 1 smoothly again for circulation, so that even when the ventilation of the filter screen 5 decreases, the air intake can still be smooth and the heat dissipation effect will not be weakened.

[0023] Specifically, such as Figure 2 As shown, the air intake device 4 includes a flip cover 13. A connecting rod 9 is fixedly installed on the upper wall of the flip cover 13. A bearing 7 is installed at the other end of the connecting rod 9. A mounting seat 8 is installed on the outer wall of the bearing 7. The mounting seat 8 is fixedly installed on the baffle 10. A horizontal plate 16 is installed at the top of the mounting seat 8. A bracket 14 is installed at the bottom of the other end of the horizontal plate 16. The bracket 14 is fixedly installed on the baffle 10. A first spring 15 is installed above the flip cover 13. The other end of the first spring 15 is connected to the lower wall of the horizontal plate 16.

[0024] By adopting the above technical solution, when the filter 5 below the first air intake plate 3 becomes clogged due to long-term use, the air intake device 4 creates a negative pressure environment inside the casing 1 under the action of the fan 2. Because the filter 5 below the first air intake plate 3 is clogged, the air intake is obstructed. Therefore, the air enters the casing 1 through the filter 5 below the second air intake plate 12. The filter 5 below the second air intake plate 12 is not used during normal use and can be kept clean. The air enters the casing 1 through the second air intake plate 12, opening the flip cover 13. The flip cover 13 rotates under the action of air pressure. 3. Rotation cancels the engagement with the through hole 11. Simultaneously, the flip cover 13 rotates, pushing the first spring 15 to contract. After the airflow enters the chassis 1, the air completes the circulation, dissipating heat from the components inside the chassis 1. Subsequently, after the gas enters the chassis 1, the air pressure inside the chassis 1 returns to normal. The flip cover 13 closes under the combined force of gravity and the first spring 15. At the same time as closing, it generates a certain impact force on the second air intake plate 12 and the filter screen 5. Under the action of the impact force, the dust on the filter screen 5 is cleaned to a certain extent, restoring the air permeability of the filter screen 5, allowing it to be used for a longer period of time.

[0025] Specifically, such as Figure 3 , Figure 4 and Figure 5 As shown, a mounting block 21 is provided at the bottom of the chassis 1. The mounting block 21 is located below the fan 2. An opening is provided inside the mounting block 21. A locking block 19 is slidably provided in the opening. A second spring 18 is provided on the upper wall of the locking block 19. A mounting cover 17 is provided on the top of the opening. The other end of the second spring 18 is connected to the mounting cover 17. A slot 20 is provided on the mounting plate 6. The slot 20 cooperates with the locking block 19.

[0026] By adopting the above technical solution, the filter screen 5 can be quickly installed and removed using the mounting plate 6 and mounting block 21. When installing the filter screen 5, it is fixedly installed on the mounting plate 6. The operator inserts the mounting plate 6 into the groove at the bottom of the housing 1 and pushes it inward. The mounting plate 6 pushes the locking block 19 upward, and the upward movement of the locking block 19 causes the second spring 18 to contract. When the mounting plate 6 is pushed to the bottom, the slot 20 on the mounting plate 6 coincides with the position of the locking block 19. Under the force of the second spring 18, the locking block 19 engages with the slot 20, thus fixing the mounting plate 6. This is convenient and quick. When removing the filter screen 5, the operator pulls the mounting plate 6. Due to the inclined surface of the slot 20 and the inverted trapezoidal design of the locking block 19, the engagement can be canceled under the action of external force. After removal, the filter screen 5 can be cleaned or replaced, which is practical and convenient.

[0027] Specifically, such as Figure 2 As shown, multiple through holes 11 are evenly provided on the baffle 10, and multiple air inlet devices 4 are required. The air inlet devices 4 are matched with the through holes 11 one by one. A sealing gasket is provided on the lower wall of the flip cover 13, and the flip cover 13 is matched with the through holes 11.

[0028] By adopting the above technical solution and setting multiple air inlet devices 4, the volume of the flip cover 13 is reduced, making it easier to open with airflow. The sealing gasket provides better sealing and prevents air leakage, making it easier to open the flip cover 13 with airflow.

[0029] Specifically, such as Figure 4 and Figure 5 As shown, two sets of locking blocks 19, spring 18, mounting cover 17 and locking slot 20 are symmetrically arranged. A limit rod 22 is provided on the side wall of the mounting plate 6. A limit groove 23 is opened at the bottom of the chassis 1. The limit rod 22 cooperates with the limit groove 23. Half of the locking block 19 is set as an inverted trapezoid, and the other half is set as a square. The square is slightly longer than the inverted trapezoid. A bevel is provided at the lower end of the outer wall of the mounting block 21.

[0030] By adopting the above technical solution, two sets of card blocks 19 are set to achieve better fixation effect. At the same time, the design of the limiting groove 23 makes it easier to install and prevents deviation. The set oblique cut allows the staff to better install the mounting plate 6 onto the chassis 1.

[0032] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
