Technical Field

[0001] The invention relates to the technical field of computer cases, in particular to a convection heat dissipation type computer case. Background Art

[0002] The computer case is the outer shell of the computer hardware, which is used to hold and protect the various hardware components inside the computer, such as the motherboard, graphics card, hard disk, etc. It is usually made of metal or plastic, has certain heat dissipation and dustproof functions, and provides various interfaces and slots for users to install and replace hardware devices. The design and size of the case will also affect the heat dissipation performance and scalability of the computer. Generally speaking, the computer case will also be equipped with components such as power supplies and fans to ensure that the computer runs stably and maintains an appropriate temperature.

[0003] Computer case cooling refers to the process of reducing the temperature inside the computer case through various cooling methods. High temperature is one of the main enemies of computer hardware operation. Excessive temperature can lead to decreased computer performance, stability problems and even hardware damage. Computer cases often use fans to introduce cold air into the case and exhaust hot air from the case to maintain air circulation. Usually there are multiple fans inside the case, such as front fans, rear fans and top fans.

[0004] In the prior art, when a computer case dissipates heat, multiple sets of cooling fans are often used to dissipate heat inside the case so that the heat inside the case is exchanged with the outside air. If the outside environment temperature is not much different from the inside temperature of the case, then under the action of the cooling fans, after the inside of the case is heat-exchanged with the outside environment, the high-temperature gas inside the case is difficult to be effectively discharged. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a convection cooling computer case to solve the technical problem in the prior art that if the external environment temperature is not much different from the internal temperature of the case, then under the action of the cooling fan, the high-temperature gas inside the case is difficult to be effectively discharged after the heat exchange between the inside of the case and the external environment.

[0006] To achieve the above object, the present invention provides the following technical solutions: a convection heat dissipation type computer case, comprising a case body and a side panel mounted therewith, wherein a plurality of cooling fans are mounted on one side of the case body, and the plurality of cooling fans are composed of a mounting frame, a driving motor and an impeller;

[0020] In summary, the present invention mainly has the following beneficial effects:

[0021] 1. The present invention arranges multiple groups of cooling fans at the front of the interior of the chassis body, wherein the external air can be sucked into the interior of the chassis body under the action of the multiple groups of cooling fans, and the external gas will be further cooled by the cooling pipe and then enter the interior of the chassis body, that is, the air with a lower temperature enters the interior of the chassis body to perform heat dissipation operation on the internal hardware thereof, and at the same time, when one group of cooling fans is in operation, its transmission shaft simultaneously drives the water wheel to rotate inside the circulation cylinder, and the interior of the circulation cylinder is filled with coolant, and then when the water wheel rotates, the coolant is sequentially refluxed to the interior of the cooling pipe through the circulation cavity, the first connecting pipe, the bottom heat sink, the side connecting pipe, the top heat sink and the second connecting pipe, thereby realizing the circulation flow of the coolant inside the chassis body, further ensuring that the temperature of the gas entering the interior of the chassis body can be further reduced, thereby improving the overall heat dissipation effect inside the chassis body;

[0022] 2. When the transmission shaft of the present invention drives the water wheel to rotate, it also drives the rotating frame to rotate. The rotating frame drives the two groups of centrifugal plates to extend radially under the action of centrifugal force, and then the extended centrifugal plates push the matching plates and the telescopic top plate to extend, wherein the end of the telescopic top plate cooperates with the inclined groove inside the descending block, and then the extension of the telescopic top plate drives the descending block to descend, and the descent of the descending block drives the rack to descend. Since the rack is meshed with multiple groups of gears, the descent of the rack drives multiple groups of flip fins to flip and open outside along their rotating shafts, so that the hot air in the chassis body can be discharged to the outside through the opened flip fins, further improving the overall heat dissipation and cooling effect.

In other words, the air with a lower temperature enters the chassis body 1 to perform forced convection cooling operation on the internal hardware;

[0040] A rotating frame 24 located on one side of the circulation drum 4 is fixed on the outside of the transmission shaft 6, and two groups of centrifugal plates 25 are movably connected on the outside of the rotating frame 24.

[0045] See also Fig.10 The rotating frame 24 and the centrifugal plate 25 are elastically connected by the first spring frame 26, and a guide frame 35 slidably connected to the telescopic top plate 27 is fixed at one end inside the chassis body 1, and a second spring frame 36 is fixed on one side between the guide frame 35 and the telescopic top plate 27. The present invention sets the above structure, wherein the centrifugal plate 25 shrinks and resets under the action of the first spring frame 26, and the telescopic top plate 27 and the matching plate 28 shrink and reset under the action of the second spring frame 36, and then the rack 31 is driven to rise and reset through the descending block 29, so that the multiple groups of flip fins 33 are closed to prevent external dust from entering the interior of the chassis body 1.

[0046] The working principle of the present invention is as follows: when in use, the chassis body 1 and the side panel 2 are installed by screws. When installing computer hardware inside the chassis body 1, the side panel 2 is disassembled and removed relative to the chassis body 1, and then the staff can install the computer hardware inside the chassis body 1, wherein the computer motherboard is installed on the motherboard installation plate 19, so that the multiple groups of interfaces at the rear of the computer motherboard correspond to the back through holes 20, and then it can be connected with external power supply equipment and networking equipment;

[0047] By arranging a plurality of cooling fans 3 at the front of the chassis body 1, the external air can be sucked into the chassis body 1 by the plurality of cooling fans 3, and the external air will be further cooled by the cooling pipe 8 before entering the chassis body 1, that is, the air with a lower temperature enters the chassis body 1 to dissipate heat for the internal hardware;

[0048] Specifically, the heat dissipation fan 3 is composed of a mounting frame, a driving motor and an impeller, wherein the driving motor is fixed inside the mounting frame, and a transmission shaft 6 connected to its output end drives the impeller to rotate to perform heat dissipation operation;

[0049] At the same time, when one of the cooling fans 3 is running, its transmission shaft 6 drives the water wheel 7 to rotate inside the circulation drum 4, and the circulation drum 4 is filled with coolant. When the water wheel 7 rotates, the coolant is sequentially returned to the cooling tube 8 through the circulation cavity 5, the first connecting pipe 9, the bottom heat sink 10, the side connecting pipe 11, the top heat sink 12 and the second connecting pipe 13, thereby realizing the circulation of the coolant inside the chassis body 1, further ensuring that the temperature of the gas entering the chassis body 1 can be further reduced, thereby improving the overall heat dissipation effect inside the chassis body 1, which effectively avoids the problem of reducing the heat dissipation effect inside the chassis body 1 when the external environment temperature is high;

[0050] Furthermore, the bottom heat sink 10 and the top heat sink 12 are distributed at the bottom and the top of the chassis body 1, and the outer sides thereof are fixed with heat conducting plates 14 in contact with the external environment space, and when the coolant flows inside the bottom heat sink 10 and the top heat sink 12, the heat conducting plates 14 can absorb the heat of the coolant inside the bottom heat sink 10 and the top heat sink 12, and then exchange heat with the external environment space, thereby further ensuring the cooling performance of the coolant;

[0051] Furthermore, the two sets of side connecting pipes 11 are installed at both ends of the chassis body 1, and mounting holes matching the two sets of side connecting pipes 11 are opened at both ends of the chassis body 1, so that the coolant inside the two sets of side connecting pipes 11 can also exchange heat with the external environment to a certain extent, thereby further ensuring the cooling performance of the coolant;

[0052] When the transmission shaft 6 drives the water wheel 7 to rotate, it also drives the rotating frame 24 to rotate, and the rotating frame 24 drives the two sets of centrifugal plates 25 to extend radially under the action of centrifugal force, and then the extended centrifugal plates 25 push the matching plates 28 and the telescopic top plate 27 to extend;

[0053] The end of the telescopic top plate 27 cooperates with the inclined groove 30 inside the descending block 29, so that the telescopic top plate 27 extends to drive the descending block 29 to descend, and the descending block 29 drives the rack 31 to descend. Since the rack 31 is meshed with multiple sets of gears 34, the rack 31 descends and drives multiple sets of flip fins 33 to flip and open along their rotation axes to the outside, so that the hot air in the chassis body 1 can be discharged to the outside through the opened flip fins 33, further improving the overall heat dissipation and cooling effect;

[0054] When the rotating frame 24 stops rotating, the centrifugal plate 25 shrinks and resets under the action of the first spring frame 26, and the telescopic top plate 27 and the matching plate 28 shrink and reset under the action of the second spring frame 36, and then the rack 31 is driven to rise and reset through the descending block 29, so that the multiple groups of flip fins 33 are closed to prevent external dust from entering the interior of the chassis body 1.

[0055] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention.
