Description

Technical Field

[0001] This utility model relates to the field of computer heat dissipation, specifically a computer cooling fan structure. Background Technology

[0002] Poor heat dissipation in a PC not only affects stability but can also cause fan noise. This is because a PC contains a large number of cooling fans: power supply fan, CPU fan, case fan, and graphics card fan. If they are not arranged properly, the cooling effect will decrease instead of increase.

[0003] However, most computer case cooling fans are located in the open holes. When the case holes are open for a long time and cooling is not required, the fan blades are prone to accumulating dust. A lot of dust can also increase operating noise. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a cooling fan structure for a computer, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a computer cooling fan structure, including a computer chassis, a detachable panel at the front of the computer chassis, a powerful air intake hole at the lower end of the detachable panel, an outer guide rail installed on the outer side of the powerful air intake hole on the side surface of the detachable panel, an outer baffle installed inside the outer guide rail, a powerful exhaust hole on the upper surface of the computer chassis, an inner guide rail installed below the powerful exhaust hole on the inner side wall of the computer chassis, an inner baffle installed inside the inner guide rail, a connecting rope connecting the inner baffle and the outer baffle, a return spring installed at the end of the inner baffle away from the connecting rope inside the inner guide rail, and an exhaust channel installed on the rear surface of the detachable panel corresponding to the position of the powerful air intake hole, with a cooling fan installed inside the exhaust channel.

[0006] As a further embodiment of this utility model: a through hole is provided on the outer side of the connecting rope inside the disassembly panel, and a limit stop is installed on the upper part of the outer baffle on the front surface of the disassembly panel.

[0007] As a further improvement of this utility model: the computer chassis has a heat dissipation hole on the left side, and a support foot pad is installed on the lower surface of the computer chassis.

[0008] As a further improvement of this utility model: the inner baffle is slidably connected to the inner guide rail, and the outer baffle is slidably connected to the outer guide rail.

[0009] As a further improvement of this utility model: the inner baffle is fixedly connected to the inner guide rail by the reset spring, and the forced exhaust vent is connected to the computer chassis.

[0012] As a further improvement of this utility model, the heat dissipation hole is configured to penetrate the computer chassis.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] By opening strong air intake and exhaust vents, the overall heat dissipation channel of the computer case can be increased. At the same time, the outer and inner baffles together form a baffle mechanism, which can open and close the strong air intake and exhaust vents simultaneously as needed, thus controlling heat dissipation and dust blocking.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-5 As shown, this embodiment provides a computer cooling fan structure, including a computer chassis 1. A removable panel 2 is located at the front of the computer chassis 1. A forced air intake vent 3 is provided at the lower end of the removable panel 2. An outer guide rail 201 is installed on the outer side of the forced air intake vent 3, located on the side surface of the removable panel 2. An outer baffle 4 is provided inside the outer guide rail 201, and the outer baffle 4 is slidably connected to the outer guide rail 201. A magnetic guide block is installed on the inner end of the outer guide rail 201. A forced exhaust vent 5 is provided on the upper surface of the computer chassis 1, and the forced exhaust vent 5 is connected to the computer chassis 1. An inner guide rail is installed below the forced exhaust vent 5, located on the inner wall of the computer chassis 1. The inner guide rail 403 has an inner baffle 402 inside, which is slidably connected to the inner guide rail 403. A connecting rope 401 connects the inner baffle 402 and the outer baffle 4. The outer baffle 4 and the inner baffle 402 are fixedly connected by the connecting rope 401. A return spring 404 is installed inside the inner guide rail 403 at the end of the inner baffle 402 away from the connecting rope 401. The inner baffle 402 is fixedly connected to the inner guide rail 403 by the return spring 404. An exhaust channel 204 is installed on the rear surface of the disassembled panel 2 at the position corresponding to the strong air inlet 3. A cooling fan 205 is installed inside the exhaust channel 204.

[0023] like Figure 2-3 As shown, in this embodiment, a through hole 203 is provided on the outside of the connecting rope 401 inside the disassembly panel 2. The through hole 203 is connected to the disassembly panel 2. A limit block 202 is installed on the upper part of the outer baffle 4 on the front surface of the disassembly panel 2. The limit block 202 is fixedly connected to the disassembly panel 2. A heat dissipation hole 6 is provided on the left side of the computer case 1. The heat dissipation hole 6 is connected to the computer case 1. A support foot pad is installed on the lower surface of the computer case 1.

[0024] The working principle of this utility model is as follows: In use, the outer baffle 4 is installed inside the outer guide rail 201, while the inner baffle 402 is fixed inside the inner guide rail 403 by the return spring 404. The outer baffle 4 and the inner baffle 402 are fixedly connected by the connecting rope 401. During normal use, the heat dissipation holes 6 on the outside of the computer case 1 provide normal heat dissipation. When the operating temperature of the components inside the case rises too high, the outer baffle 4 is pulled out from inside the outer guide rail 201, breaking the attraction of the internal magnetic block to the outer baffle 4. The outer baffle 4 then moves upward and stops at the limit block 20. Under the action of 2, the outer baffle 4 is unblocked from the strong air intake vent 3, and the inner baffle 402 is reset and pulled by the reset spring 404. Then the inner baffle 402 is unblocked from the strong exhaust vent 5, thus opening another heat dissipation channel inside the computer case 1. By starting the cooling fan 205 inside the exhaust channel 204, the internal heat can be discharged from the position of the strong exhaust vent 5. When the case temperature drops, the outer baffle 4 is pushed down inside the outer guide rail 201, which again blocks the passage of the strong air intake vent 3 and the strong exhaust vent 5, thus reducing the amount of dust entering the computer case 1 during daily use.
