Description

Technical Field

[0001] This utility model belongs to the field of computer chassis technology, specifically relating to a computer chassis with a front fan. Background Technology

[0002] The computer case is an important component of a computer, mainly used to house and secure the various parts. To ensure the proper functioning of the core circuitry components inside the computer case, cooling fans are typically installed.

[0003] Currently, the common heat dissipation designs for computer cases adopt the following solutions: fixed front panel + independent switch, with the fan fixed at the front of the computer case and controlled to start and stop via an independent physical switch or software; split heat dissipation structure, where the cooling fan and airflow adjustment device are separated and rely on the collaboration of multiple components; static contact design, where circuit conduction relies on fixed contacts.

[0004] Existing computer case cooling methods have several problems and drawbacks, such as requiring manual operation of switches or software adjustment, increasing user interaction steps and making operation redundant; complex structure; and redundant cables. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a computer case with a front-mounted fan that improves heat dissipation performance, simplifies operation, and streamlines the structure.

[0006] To solve the above-mentioned technical problems, this utility model provides a computer case with a front-mounted fan. Its main feature is that the computer case includes a casing with a front opening, the front opening having an openable front panel, the front panel being hinged to the casing via a hinge assembly, and opening and closing achieved by rotating the front panel. A cooling fan and a first circuit board electrically connected to the cooling fan are disposed on the inner side of the front panel. The first circuit board has a first contact, and the casing has a second circuit board with a second contact. Closing the front panel causes the first contact of the first circuit board and the second contact of the second circuit board to contact each other, thereby operating the cooling fan; opening the front panel causes the first contact of the first circuit board and the second contact of the second circuit board to disengage, thereby stopping the operation of the cooling fan.

[0010] Preferably, a limiting component is provided between the inner side of the front panel and the housing. The limiting component includes a limiting pin and a limiting hole that matches the limiting pin. The limiting pin is provided in one of the inner side of the front panel and the housing, and the limiting hole is provided in the other of the inner side of the front panel and the housing.

[0011] Preferably, the hinge assembly includes a hinge shaft and a mounting hole, the mounting hole being disposed on the chassis and the hinge shaft being disposed on the inner side of the front panel.

[0012] Preferably, the first contact is an elastic contact.

[0013] Preferably, the elastic contact is a metal spring sheet structure.

[0014] Preferably, the front panel includes a first panel located on the inner side and a second panel located on the outer side, wherein the area of ​​the first panel corresponding to the cooling fan is a cut-out area, and the area of ​​the second panel corresponding to the cooling fan is a mesh area.

[0015] This utility model features a computer chassis with a front-mounted fan, which effectively improves ventilation by 2% and reduces temperature by 2 degrees Celsius (at a constant temperature and humidity of 25°C), thus enhancing heat dissipation performance. During operation, it can complete start-up and shutdown with a single action, reducing the need to shut down the computer unnecessarily to check the computer hardware's operating status and simplifying operation.

[0019] To make the technical problem solved by this utility model clearer, the present utility model is further described below with reference to embodiments and accompanying drawings. The specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0020] like Figures 1 to 3 The illustration shows an embodiment of a computer chassis with a front-mounted fan, integrating a heat dissipation system and electromechanical linkage control. It is particularly suitable for integrated devices that achieve fan positioning, contact conduction, and heat dissipation airflow adjustment via a movable front panel. The computer chassis includes a housing 1 with a front opening. The front opening is fitted with an openable front panel 2, which is hinged to the housing 1 via a hinge assembly. Rotating the front panel 2 opens and closes the front opening of the housing 1. The hinge assembly can utilize a combination of a hinge shaft and mounting holes; for example, the mounting holes are located on the housing 1, and the hinge shaft is located on the inner side of the front panel 2.

[0021] The front panel 2 has two cooling fans 3 and a first circuit board 4 electrically connected to the cooling fans 3 on its inner side, and the casing 1 has a second circuit board 5. Figure 2 As shown, the first circuit board 4 has a first contact 9, and the second circuit board 5 has a second contact 10. The first contact 9 can be an elastic contact. The elastic contact can be a metal spring sheet structure, used to form a conductive state when in physical contact, and to cut off power when disconnected.

[0022] By closing the front panel 2, the first contact 9 of the first circuit board 4 and the second contact 10 of the second circuit board 5 come into contact to operate the cooling fan 3; by opening the front panel 2, the first contact 9 of the first circuit board 4 and the second contact 10 of the second circuit board 5 disengage to stop the operation of the cooling fan 3.

[0023] Therefore, this utility model achieves contact communication between the first and second circuit boards by rotating and opening the front panel, which integrates a cooling fan. The integrated electromechanical linkage design of the rotating panel and the interlocking contacts enables synchronous control of the cooling airflow adjustment and circuit conduction, eliminating the wiring redundancy of the split structure. Closing the front panel conducts current through the contacts, achieving the effect of powering the fan; opening the front panel disconnects the current, and the fan stops rotating. When the computer is powered on and in normal use, the front panel is closed, and the fan rotates. If it is necessary to check the hardware operation status without powering on, the front panel can be easily rotated to open, and the fan will immediately stop rotating, reducing the danger of the rotating fan to the operator.

[0024] like Figure 1As shown, a main circuit board 8 is disposed inside the casing 1, and the main circuit board 8 is electrically connected to the second circuit board 5. The first circuit board 4 is provided with an interface for connecting the cable connector of the cooling fan 3.

[0025] like Figure 1 and Figure 2 As shown, a snap-locking assembly is provided between the inner side of the front panel 2 and the housing 1. The snap-locking assembly includes a mushroom head 6 and a snap 11 that matches the mushroom head 6. The mushroom head 6 is located on the inner side of the front panel, and the snap 11 is located on the housing 1, so as to realize quick release and quick locking.

[0026] like Figure 1 and Figure 2 As shown, a limiting component is provided between the inner side of the front panel 2 and the housing 1. The limiting component includes a limiting pin 7 and a limiting hole 12 that matches the limiting pin 7. The limiting pin 7 is provided on the inner side of the front panel 2, and the limiting hole 12 is provided on the housing 1 to guide the assembly accuracy and strength of the front panel.

[0027] In this embodiment, the front panel 2 includes a first panel located on the inner side and a second panel located on the outer side, that is, the front panel has a double panel structure. The area of ​​the first panel corresponding to the cooling fan is a cut-out area for installing the cooling fan. The area of ​​the second panel corresponding to the cooling fan is a mesh area 13. The cut-out area of ​​the first panel and the mesh area of ​​the second panel can retain the fan air duct, which is conducive to ventilation.

[0028] This utility model features a computer chassis with a front-mounted fan, which effectively improves ventilation by 2% and reduces temperature by 2 degrees Celsius (at a constant temperature and humidity of 25°C), thus enhancing heat dissipation performance. During operation, it can complete start-up and shutdown with a single action, reducing the need to shut down the computer unnecessarily to check the computer hardware's operating status and simplifying operation. It can also achieve modular installation and modular electrical isolation, simplifying the structure and reducing the difficulty of user operation.

[0029] The above descriptions are specific embodiments of this utility model and do not constitute a limitation on the scope of protection of this utility model. Any modifications and variations made to the technical concept of this utility model should be included within the scope of protection of this utility model.
