Description

Partition in the mainframe
The novel creation relates to the technical field of computer hardware devices, and in particular to a technology for a partition in a computer mainframe.
The mainstream of the existing traditional desktop computer mainframe is a tower mainframe, and its overall shape is a rectangular parallelepiped. The mainframe of the desktop computer is divided into horizontal and vertical, and is usually the most common in vertical. All physical components in the mainframe are generally referred to as computer hardware, including motherboards, hard drives, CPUs, memory sticks, stand-alone graphics cards, optical drives, and power supplies, as well as heat sinks. The existing tower mainframe is a non-slim mainframe, which is large in size and heavy in weight.
1) Hardware configuration and routing: At present, the hardware configuration in the traditional desktop mainframe is designed to be able to install almost one type of computer hardware in one location space, so in order to support more hardware, the main chassis Set a lot of hardware installation space location, when some hardware installation location is not used, it can only be idle there, greatly wasting the space volume inside the mainframe, making the space utilization in the mainframe low .
Most of the data or power connection between the hardware in the mainframe of the traditional desktop computer is the RVV wire, and the associated hardware is connected through the wire. Connected together. However, due to the backward layout and routing in the traditional mainframe, and the various hardware, the connecting wires are also criss-crossed, complicated and complicated. The user needs to have certain professional basic knowledge and serious influence. The interior of the main box is beautiful, and the various lines also occupy the space volume in the main box. In the traditional mainframe, due to the unreasonable reason of the hardware configuration, and the connection of the common wires, and the connection distance between the hardware is not the shortest, the shortest connection cannot be achieved because it is too short. Ordinary wires become thick and hard, so it is very inconvenient for users to install and use.
2) Structure of the CPU heat sink and its installation: The traditional CPU heat sink uses 4 screws/expansion bayonet pins to fix the CPU heat sink through the CPU mounting holes on the motherboard, rigid or nearly rigid material and structure. On the motherboard. The following five problems often occur: First, because the screw/expansion pin is tightened too much, the force between the heat sink and the motherboard is too large, causing the motherboard to deform and bend to varying degrees. Second, sometimes the four screws are unbalanced when they are tightened, resulting in partial tilting between the surface of the CPU chip and the heat-conducting base of the heat sink, resulting in fine gaps, which greatly increases the thermal conductivity of the CPU chip and the heat sink. The thermal conductivity between the two blocks the heat transfer between the CPU chip and the heat sink. Third, the traditional CPU heatsink and the matching buckles and parts are numerous and complicated to install. Most of them take several minutes to ten minutes. Fourth, when some conventional CPU heat sinks are mounted on the motherboard, they cannot move or can only move in one direction. As a result, sometimes the CPU heatsink conflicts with the position of some components on the motherboard, and the drawbacks of normal installation cannot occur. Fifth, most traditional high-end CPU heat sinks can only increase the size of the heat sink in order to achieve better heat dissipation. Body type. This greatly reduces the compatibility of the large CPU heat sink with the main chassis and the motherboard, and the cost of the user purchase is also significantly increased.
In addition, most of the CPUs used by ordinary users consume less than 100W of TDP power. However, considering the demanding requirements of top CPUs and overclocking users, the CPU heatsink can carry more than 180W. Therefore, higher requirements are placed on the performance of the heat sink.
3) Installation and heat dissipation of the independent display card: The independent display card in the traditional desktop mainframe, if it is a low-end display card, generally uses the original heat sink of the display card for heat dissipation. In the case of high-power, high-end graphics cards, either use expensive, cumbersome water-cooling solutions or reinstall better air-cooled heat sinks. However, most of the independent display card air-cooled radiators on the market have a certain compatibility range, or there are many matching parts and the installation process is cumbersome. And users who don't have a certain amount of expertise don't even know what kind of radiator should be chosen.
In the traditional desktop mainframe, the independent display card has the following problems in terms of heat dissipation:
First, if the independent display card is air-cooled, the size of the heat sink can hardly exceed the size range of the display card itself due to the limitation of the mounting method and size specifications. And the matching fan also occupies a part of the volume of the heat sink, so the actual heat dissipation area of the heat sink is limited.
Second, if water cooling is used, the high cost will not be said. Water tanks, pumps, radiators, fans, water pipes, etc., which are compatible with water cooling, need to increase the volume and weight of the main box. And the installation is cumbersome, and users need to have certain specialization when installing water cooling. Industry ability.
Third, the independent display card is perpendicular to the air inlet of the main panel side panel. If air cooling is adopted, the cold air flowing in from the air inlet is interfered by the CPU cooling fan and the display card cooling fan, and the cold air outside the main box cannot flow completely and unidirectionally through the independent display card. Efficient heat dissipation in the radiator, because the unscientific and tight air duct in the main box, the cold air flowing into the independent display card and the CPU radiator is caught with the returning hot air, which affects the heat exchange effect of the radiator.
Fourth, the independent display card heat sinks are placed horizontally in parallel, which is very unfavorable for the natural upward movement of the air heat flow.
In the traditional desktop mainframe, the independent display card is directly inserted vertically into the display card slot of the motherboard. Since the motherboard and the independent display card are both large-sized hardware in the main chassis, the space occupied by the two perpendicularly is large. But this way is very compatible with the hardware.
4) Cooling air duct: The design of the heat dissipating air duct in the traditional desktop main box is unscientific and disorderly, and almost all of them have the phenomenon of returning hot air. In order to increase the heat dissipation effect of the CPU or the independent display card, it is solved by increasing the size of the heat sink. There is no simple and effective way to transfer and diffuse a part of the heat source by means of the metal casing of the main box itself.
In addition, the fan speed and the noise generated by it have always been a major contradiction between air cooling and heat dissipation. The fan speed in a conventional desktop mainframe usually has two forms: one is a fixed speed, and the other is a temperature-controlled speed by connecting a motherboard PWM jack. The former, regardless of the temperature inside the main box is always a speed, unscientific; In the latter case, the fan must first have the PWM function, and then enter the motherboard BISS to open and set, the user needs to have certain professional knowledge. Moreover, there are many types of fans, and if the fan in the PWM speed control mode is too noisy or the wind speed is too small, there is almost no way for the user to effectively adjust.
5) Power supply: The power supply box in the traditional desktop mainframe is large in size. Its function is to directly convert the input AC power into DC output of different voltage values required by each hardware, and connect with each hardware by using many RVV wires. In addition, the design configuration in the traditional mainframe is backward, which causes the various wires of the inner box of the mainframe to be densely packed and criss-crossed. The huge occupation wastes the space volume in the mainframe and affects the appearance of the mainframe, and also hinders the convenience of the user. .
In order to overcome the shortcomings of the existing product technology, the present invention aims to provide a hardware device that can be reconfigured to concentrate the required connection lines between the hardware into an ultra-thin circuit and has a hidden effect, which can greatly reduce the size and weight of the host. The partition in the mainframe provides superior support for designing ultra-thin hosts.
A further goal is to install computer hardware accurately and quickly.

The above-mentioned embedded PCB circuit board has a tight covering of the insulating and wear-resistant layers on the entire surface.
The partition plate is made of the same material as the metal casing or the skeleton of the computer main body, and is integrally formed by hot-melting or squeezing the material through a mold, and the partition plate is integrally formed with the metal casing or the skeleton of the computer case; or the above-mentioned partition plate and The metal frame or outer casing of the computer mainframe is separated and independent, and the partition plate is welded and fixed to the metal frame of the chassis or the inner wall of the outer casing.
The baffle sockets are directly soldered or contacted to the corresponding baffle circuit. The hardware interface type of the partition socket includes SATA 2.0 data interface, SATA 3.0 data interface, SATA Express hard disk interface, SAS hard disk interface, SATA 7+15pin data + power hard disk interface, SATA 7+6pin data + power supply CD Machine interface, motherboard boot pin POWER SW, motherboard restart pin RESET SW, USB 3.0 19/20pin jack, USB 2.0 9pin jack, motherboard audio pin HD AUDIO, standalone graphics card PCI-E 16X The slot, the motherboard main power supply 24pin slot, the motherboard auxiliary power supply 4/8pin slot and the independent display card auxiliary power supply 6/8pin slot, or any combination of the above hardware interfaces.
The bottom of the baffle socket is arranged with the corresponding pins of the socket, and the soldering point is arranged at the corresponding mounting position of the baffle circuit, and the pins at the bottom of the baffle socket are directly soldered and fixed at the corresponding baffle circuit position. Or the bottom of the spacer socket is arranged with the corresponding pins of the socket, and the pins are exposed conductive metal The elastic piece is in the form of a protruding positioning pin at the periphery of the elastic piece at the bottom of the partition socket, and a corresponding mounting position on the partition has a concavely-shaped mounting area, and the inner concave area is arranged in an orderly manner.

The present application discloses another technical solution: a partition in a computer main body, wherein: the partition divides a computer mainframe space into two, the partition is provided with a front side and a back side, and the partition substrate is electrically conductive.

The beneficial effect of the novel creation is that the novel creation can re-lay most of the hardware in the computer mainframe, significantly reducing the volume and weight of the computer mainframe, and concentrating the required connection lines between the hardware into an ultra-thin circuit and having a hidden effect. Provides strong support for designing ultra-thin chassis. The ultra-thin mainframe is about 1/6 of the size of a traditional full-tower chassis. In the case of full-load hardware, the ultra-thin mainframe is about half the weight of a traditional full-tower chassis. This ultra-thin host can meet almost all common motherboard models (such as ATX, M-ATX, ITX, etc.) currently installed on the market. It can be installed to support all 3.5-inch hard drives, 2.5-inch hard drives, and can be installed to support all full heights. The semi-high, ultra-long, high-power independent display card can be installed to support thin optical disc drives within 14mm thickness. The hardware in the main chassis has been reconfigured and the connection form is defined. There is a metal plate in the box, and the hardware is arranged in parallel on both sides of the metal plate. The user can disassemble and assemble the required hardware extremely quickly and accurately; the main box has a matching integrated type. The U-shaped slider housing (this slider housing is available in a transparent, translucent material) provides an extremely simple operating mode for the user to open/close the main unit. The whole machine also has excellent heat dissipation performance and humanized one-button intelligent temperature control system. The CPU heatsink, stand-alone display card heatsink, power supply box, and exhaust fan in this slim host are custom-sized models that match this slim host.
The setting of the specific related components of the present application has the following advantages:
1) The main board support column on the partition is the same as the traditional one, but There is one more use here. Because the motherboard support column is electrically conductive and connected to the separator. Because this ultra-thin chassis is designed with the metal separator as the DC negative pole of the whole machine and the grounding bearing main conductor. The mounting hole of the PC type motherboard is connected with the output DC negative pole and the grounding position of the motherboard, and is fixed to the supporting plate of the motherboard on the partition plate through the mounting hole of the motherboard through the conductive screw or the bayonet, thereby realizing the motherboard The part of the DC negative pole/ground is directly connected to the metal baffle, and part of the DC negative/ground ground output from the main board is transmitted to the metal baffle through the support plate of the main board, and then the bottom of the power supply box and the metal baffle plate have a large area. Touch back to the power box. In the traditional PC mainframe, a large number of wires are connected to the power supply slot of the motherboard, and all the DC negative output of the motherboard is directly transmitted back to the power supply box, which requires a large number of wires and takes up a lot of space.
2) The cover plate is concealed/covered with an ultra-thin flat circuit, which may be referred to as a "invisible circuit spacer". By redefining the configuration in the mainframe, the hardware compatibility is excellent (supporting more than 99% of the common hardware on the market). It also ingeniously realizes that the same position space can be installed according to different needs of users, and the chassis volume is reduced to a minimum when the utilization of the space position in the chassis and the free collocation are improved: First, the invisible circuit is separated. The board efficiently solves the signal and power transmission between the hardware, reconfigures the hardware, and greatly reduces the size of the chassis. Second, it provides a platform for mounting the fixed support for each hardware. Third, because of the partition of the metal matrix. It is connected to the metal casing of the chassis to provide good thermal and thermal support for the hardware attached to the back of the partition in parallel.
3) The spacer socket is directly or indirectly connected to the hardware in the chassis according to different interface types of the hardware; the advantage of the FFC line is super Thin, flexible, and capable of passing large currents, suitable for the short distance between the bulkhead and the hardware. The bulkhead sockets are soldered or contacted directly to the corresponding bulkhead circuit.
First, some hardware in the chassis can be directly plugged into a matching bulkhead socket for use. Such as 3.5-inch, 2.5-inch hard disk, because it is a more common use of hardware, so that the design can be used directly, very fast and user-friendly. For hardware that cannot be plugged directly into the bulkhead socket, the shortest thread connection concept is used to connect the hardware to the matching bulkhead socket with a cord. It also greatly reduces the wiring between the hardware, making the whole machine simple and beautiful.
Second, the movable partition socket is generally used for the design of different hardware in the same partition position. That is, increase the number and type of hardware that can support expansion in the chassis without increasing the size of the chassis.
Third, since the mounting position of the movable bulkhead socket on the bulkhead circuit is an inner concave area, there is a circuit contact point of the bare conductor in the concave area. When other hardware is installed at the same position, the surface height of the bare circuit contact point in the recessed area is lower than the height of the surrounding spacer surface, so that a short circuit is not caused by touching other hardware. When the recessed area is not used, the recessed area can be filled with a matching insulating patch to provide isolation insulation and dustproof.

In the groove, the partition 3 groove and the PCB circuit board The surface is subjected to an insulating coating treatment, and the PCB circuit board is seamlessly fastened in the corresponding groove of the separator 3 by an adhesive. After tightening, the surface height of the PCB circuit board is basically the same as the height of the board surface of the partition plate 3, and finally the insulating and wear-resistant coating is applied on the entire surface of the partition plate 3 in which the PCB circuit board is fastened. Therefore, the partition 3 is integrated with the surface of the PCB circuit board, and the circuit inside is hardly seen.
Since the heat dissipation and heat dissipation of the back surface of the separator 3 is required, and the simplified design and process are integrated, the PCB circuit board is uniformly embedded in the front surface of the separator 3.
Preferably, the partition plate 3 is an ultra-thin insulating copper plate embedded with the partition plate 3, that is, a process of etching, CNC milling or die-molding, and processing the position of the metal plate (separator 3) where the wire is required to be processed into a place. The desired shape and size of the groove. Etching or die stamping process is used to make copper sheets with a thickness of 0.05~0.5mm into various traces required for design, and the outermost outlines of these copper traces are densely arranged with the metal plate ( The shape and size of the grooves on the partition 3) match. The groove on the metal plate (separator 3) and the processed ultra-thin copper piece are routed, the surface is insulated, and finally the ultra-thin insulating copper piece is closely embedded in the metal plate (separator 3) by an adhesive. In the corresponding groove position, the surface height of the ultra-thin copper wire is not higher than the surface height of the surrounding metal plate (separator 3). This process scheme is suitable for designing circuit traces that are arranged with excessive current on a metal plate (separator 3).
Preferably, the partition 3 is an FPC flexible wire interposer 3, except that the embedded circuit material is an FPC flexible wire, the other processes embedded in the separator 3 and the above-mentioned "glass fiber/semi-glass fiber-based printed circuit" The embedded partitions 3" are substantially identical.
Preferably, the separator 3 is a metal-based conductive coating circuit separator 3, that is, in a metal The surface is covered with an insulating layer, and then coated with a liquid/colloidal/powder conductive coating on the insulating layer to form a desired trace circuit, and then air-dried or cured at a high temperature to form a stable conductive circuit coating, and finally The entire circuit board 3 is covered with an insulating and wear-resistant layer (except for a partial area connecting the bulkhead sockets). The coatings and processes used in this solution are relatively expensive.
The partition plate 3 is made of the same material as the metal casing or the skeleton of the mainframe of the computer, and is integrally formed by heat-melting or extruding the material through a mold. The metal frame or the outer casing of the partition 3 and the mainframe of the computer may also be separated and separated, and the partition 3 is welded and fixed to the metal frame of the main box or the inner wall of the outer casing. Because the partition 3 is connected to the metal casing of the main box, it provides good heat conduction and heat dissipation support for the hardware attached to the surface of the partition 3 in parallel. The above-mentioned "metal case of the main chassis" is the "main case 1" in the figure.
The manufacturing method of the partition 3 with the metal invisible circuit and the metal shell or the skeleton of the main box is fixed: the integral type, that is, the partition 3 and the metal shell or the skeleton of the main box are of the same material, and the material is thermally melted by the mold. Or integrally formed after extrusion. Then, the process is processed on the partition 3 in the formed main box, so that the ultra-thin circuit traces required for the design are arranged on/in the partition 3; the reflow soldering, the partition 3 and the metal frame or the outer casing of the main box are Separate and independent, the ultra-thin circuit traces required for the design have been processed on/in the separator 3, and then the solder joint is applied to the metal frame of the main frame or the inner wall of the outer casing. After the combination is matched, it is placed in a reflow device for reflow soldering. After cooling out, the partition 3 is tightly fixed to the metal frame or outer casing of the main box.
03) partition socket
The separator socket is directly soldered or contacted to the circuit of the corresponding partition 3. The hardware interface type of the partition socket includes SATA 2.0 data interface, SATA 3.0 data interface, SATA Express hard disk 203 interface, SAS hard disk 203 Interface, SATA 7+15pin data + power hard disk 203 interface, SATA 7+6pin data + power supply CD player 204 interface, motherboard 4 boot pin POWER SW, motherboard 4 restart pin RESET SW, USB 3.0 19/20pin socket, USB 2.0 9pin jack, audio pin HD AUDIO for motherboard 4, PCI-E 16X slot for independent display card 7, main power supply 24pin slot for motherboard 4, auxiliary power supply for motherboard 4/ The 8pin slot and the auxiliary power supply 6/8pin slot of the independent display card 7, or any combination of the above hardware interfaces. Some hardware in the main chassis can be directly inserted into the bulkhead socket, and some need to be connected to the corresponding bulkhead socket through the FFC wire, so the bulkhead socket is matched with the hardware. , with different interface category types and shape sizes. The bulkhead sockets interface the hardware in the main chassis with the corresponding bulkhead circuit 32 according to the interface type of the different hardware. The advantage of the FFC line is that it is ultra-thin, soft, accurate, and capable of passing a large current. It is suitable for short-distance docking between the partition socket and the hardware.
The "separator socket" described above is a general term for the following "welded/fixed bulkhead socket" and "movable bulkhead socket".
The bulkhead sockets are divided into welded and movable types according to the configuration and design requirements in the main chassis. The soldering type, the bottom of the "separator socket" is arranged with the corresponding pins (pins) of the socket, and the corresponding position of the spacer circuit 32 has solder joints, which will be separated. The pins (pins) at the bottom of the board socket are directly soldered to the solder joint locations of the corresponding bulkhead circuit 32. The soldered bulkhead sockets are also referred to as fixed bulkhead sockets 34.
In the movable type, the bottom of the "baffle socket" is arranged with the corresponding pins (pins) of the socket, and these pins (pins) are in the form of exposed conductive metal domes 104, and the metal at the bottom of the "separator socket" There are a plurality of positioning pins 94 around the shrapnel 104. The movable partition socket 35 is generally used for the design of different hardware in the same partition 3 position, that is, the number and type of hardware capable of supporting expansion in the main box can be increased without increasing the volume of the main box.
The area of the baffle circuit 32 for mounting the "moving baffle receptacle 35" has a concave configuration 33 in which the exposed conductive, flat circuit contacts are arranged in an orderly manner. The "circuit contact point" is "Inner concave contact point 33" in the figure. There are a plurality of positioning holes 36 in the partition 3 on the outer periphery of the concave area, and the size, the number, and the hole distance of the positioning holes 36 are completely identical with the matching positioning pins 94 at the bottom of the "moving bulkhead socket 35". .
When the bottom of the movable bulkhead receptacle 35 faces the mounting area on the bulkhead circuit 32, only the circuit contact point configuration specifications in the recessed area of the movable partition receptacle 35 of the interface type and the spacer circuit 32 are specified. When the circuit definition and the socket direction are completely matched, the positioning pin 94 at the bottom of the movable partition socket 35 can be inserted into the positioning hole 36 of the concave portion of the partition circuit 32, and finally the movable type by the screw/expansion bayonet The spacer socket 35 is fixed on the partition plate 3. At this time, the conductive metal dome 104 at the bottom of the movable spacer socket 35 and the circuit contact points in the concave portion of the spacer circuit 32 are completely and accurately connected to each other. . Due to the movable partition socket 35 in the partition The mounting position on the circuit 32 is an inner concave area having exposed circuit contact points in the concave area. When other hardware is installed at the same position, the surface height of the bare circuit contact point in the concave area is lower than the surrounding space. The height of the surface of the board 3, so there is no short circuit caused by touching other hardware. When the recessed area is not used, the recessed area can be filled with a matching insulating patch to provide isolation insulation and dustproof.
Briefly, the bottom of the spacer socket is arranged with the corresponding pins of the socket, and the corresponding mounting position of the spacer circuit 32 has soldering points, and the pins at the bottom of the spacer socket are directly soldered and fixed to the corresponding spacers. The board circuit 32 is positioned; or the bottom of the bulkhead socket is arranged with the corresponding pins of the socket, and the pins are present in the form of bare conductive metal domes 104 around the shrapnel 104 at the bottom of the bulkhead socket. The positioning pin 94 is disposed, and the area for mounting the partition socket on the partition 3 has a concave structure, and the exposed conductive and flat circuit contact points are arranged in the concave area, and the outer periphery of the concave area The partition plate 3 is provided with a corresponding positioning hole 36. The partition hole is fixed to the partition plate 3 by a screw/expansion bayonet. The conductive metal dome 104 at the bottom of the partition plate is in contact with the circuit in the concave area on the partition plate 3. Point one by one to accurately touch the conduction.
Some hardware in the main chassis can be directly inserted into the "separator socket", such as 3.5-inch, 2.5-inch hard disk 202, because it is a more commonly used hardware, so that the design can be used directly, very fast and user-friendly . Hardware that can't be directly plugged into the “Baffle Socket” uses the concept of the shortest thread connection. The cable is used to connect these hardware to the matching “separator socket”, which greatly reduces the hardware. The wiring is made to make the whole machine simple and beautiful.
04) Motherboard 4 orientation
As described above, the main board 4 is abutted against the front surface of the partition 3, and is fixed in parallel to the main board support column 31 on the front side of the partition 3. Because the mainframe is of vertical design, on the one hand, the center of gravity of the whole machine should be moved down as much as possible, and the end of the motherboard 4 close to the CPU is obviously biased, and the downward placement can lower the overall center of gravity of the mainframe, so that the host The box is more stable in the vertical mode; on the other hand, the main box is vertical, and the air heat flow inside is continuously rising, and is concentrated in the upper space of the main box, and the temperature of the lower airflow of the main box relative to the upper air flow. To be low, the north end of the motherboard 4 near the CPU is placed downward, which is more conducive to the heat dissipation effect of the CPU heat sink 6 in the airflow.
Therefore, the north end side of the motherboard 4 near the CPU position is downward (can be vertical, or the angle between the downward direction and the vertical direction) 5°), the west end of the motherboard 4 (ie, one end of the motherboard I/O interface group 41) faces the tail 13 of the main chassis, and the back of the motherboard 4 faces the front of the partition 3, and is fixed to the main board support parallel to the partition 3. On the column 31. Due to the angular position between the north end side and the west end side of the main board 4, there is a main board auxiliary power supply slot 46, which is projected on the front side of the partition 3 on the north end side of the main board 4 on the principle of the near-line connection. There is a bulkhead socket on the front side of the partition 3 adjacent to the motherboard auxiliary power supply slot 46. The bottom pin (pin) of the baffle socket is sequentially connected to the output +12V DC and the DC negative (ground) in the baffle circuit 32, respectively, through one end of the wire and the main board auxiliary power supply slot 46 on the main board 4. In communication, the other end of the wire is inserted into the bulkhead socket to communicate with the corresponding power supply circuit of the partition 3 and the motherboard auxiliary power supply slot 46 on the motherboard 4.
That is, the motherboard 4 is a motherboard that is placed against the front of the partition 3 and is close to the CPU. 4 The north end side faces downward, and one end of the motherboard 4, that is, one end of the motherboard I/O interface group 41 faces the tail of the main chassis. Projected on the north end of the motherboard 4 to the area on the front side of the partition 3, a partition receptacle is disposed on the front side of the partition 3 adjacent to the auxiliary power supply slot of the motherboard 4, and the bottom pin and partition circuit 32 of the bulkhead socket The connection is connected to the motherboard auxiliary power supply slot 46 on the motherboard 4 through a wire, and the other end of the wire is inserted into the bulkhead socket to connect the corresponding power supply circuit on the partition 3 with the motherboard on the motherboard 4. The power supply slots 46 are in communication.
05) CPU heat sink and CPU heat sink mounting fixture
The heat sink of the computer CPU includes a CPU additional heat sink 64 and a CPU heat sink 6. The CPU heat sink 6 is fixed by an H-bridge clamp device, that is, the mounting and fixing device of the CPU heat sink, the H-bridge press buckle The bracket comprises two sliding rods 52. The middle sections of the two sliding rods 52 are in parallel with each other. Both ends of the two sliding rods 52 are bent at an angle of 45° outward, at the two ends of the two sliding rods 52. Each of the bent sections has a support post 51 movable on the section. The bottom of the support post 51 has an expansion chuck. The size and shape of the expansion chuck are the same as the CPU heat sink 6 on the motherboard 4. The mounting holes are matched. Then, there are four movable support columns 51 at the two ends of the two sliding rods 52. Because of different types of the motherboard 4, the hole spacing between the mounting holes of the four CPU heat sinks 6 is different, so the sliding rod The support columns 51 at both ends of the 52 are designed to be movable, and can meet the hole spacing requirements of various mounting holes of the CPU heatsink 6, and are matched and fixed. The H-type bridge buckle bracket is the aforementioned buckle 5. The support post 51 is also referred to as a clip support post.
A bridge bar 53 which is freely movable in the direction of the axis of the two slide bars 52 is provided in a section parallel to the middle of the two slide bars 52, and the intermediate section of the bridge bar 53 has an inner groove structure. The two sliding rods 52 are resilient material members or the bridge pressing rods 53 are resilient material members. Since the sliding rod 52 of the buckle 5, the bridge bar 53 and even the convex structure on the back surface of the heat-conducting base are of a resilient characteristic material, the heat-conducting base and the CPU chip 42 are not caused by excessive force or imbalance during manual fastening. The thermal conductivity of the contact between the surfaces is excessively changed, and it is also difficult to deform and bend the main board 4. The two sliding rods 52 and the bridge pressing rods 53 are combined to form the "H" type structure, so the fastener 5 of the CPU is referred to as an "H-shaped bridge fastener bracket".
One end of the CPU additional heat sink 64 is a flat vacuum heat pipe evaporation end, and the other end is a vacuum heat pipe condensation end to which the (CPU) heat sink fin 63 is welded, and the CPU is attached to the heat sink 64. The corrugated tube greatly enhances the flexibility of the (CPU) vacuum heat pipe 62, making it easier for the user to operate and adapt to different types of motherboards 4. The bottom of the condensation end of the CPU additional heat sink 64 is flat, and is fixed on the inner wall of the metal shell of the main box closest to the CPU by screws or snaps, thereby transferring part of the heat of the CPU heat-conducting base 61 to the metal shell of the main box. The heat is dissipated from the heat sink fins on the condensation end of the CPU attached heat sink 64.
The CPU heat sink 6 is a vacuum heat pipe type heat sink, and the bottom of the CPU heat sink 6 has a heat conducting base mounted on the CPU chip 42. On the edge of the heat-conducting base of the CPU heat sink 6, there is a groove perpendicular to the direction of the vacuum heat pipe arranged on the heat-conducting base, and the shape of the groove is just matched with the evaporation end of the CPU additional heat sink 64, and the CPU is attached. The evaporation end of the heat sink 64 fits into the side of the heat conductive base After the groove in the edge, fasten it to the edge of the heat-conducting base with a cover plate and a screw. The front side of the thermally conductive base is directly parallel to the surface of the CPU wafer 42. The substantially central position of the back surface of the heat-conducting base has a convex structure, and the concave sliding groove of the middle portion of the bridge pressing rod 53 can just buckle the protruding structure, and the bridge pressing rod 53 is placed on the back surface of the heat-conductive base. Since the bridge pressing rod 53 of the buckle 5 passes through the convex structure at the center position of the back surface of the heat-conducting base, the downward pressure generated when the buckle 5 is tightened is concentrated on the central area of the heat-conductive base, so that the heat-conductive base and the CPU chip 42 are interposed. The contact surfaces are evenly stressed, making the thermal conductivity between them stable.
The heat conducting base is a convex structure that is fastened to the back surface of the CPU wafer 42 by the bridge pressing rod 53, and the bridge pressing rod 53 is movably fixed to the two sliding rods 52, and the two sliding rods 52 are movable. The chucks on the support columns 51 are respectively inserted into the mounting holes of the four CPU heat sinks 6 on the motherboard 4, and finally the expansion pins 54 are inserted into the pin holes in the support, thereby connecting the entire buckle 5 brackets together with the CPU heat sink. 6 is fastened together on the motherboard 4. Since the convex structure on the back surface of the heat conducting base can move in the concave sliding rail groove in the bridge pressing rod 53, the bridge pressing rod 53 can move on the sliding rod 52, so that the entire CPU heat sink 6 can be in any direction in the plane of the motherboard 4. The small-scale translation greatly reduces the probability that the edge of the CPU heat sink 6 cannot be properly installed due to the conflict with the position of the component on the motherboard 4.
The CPU additional heat sink 64 adopts a movable installation mode, and the user can freely select whether to install according to the demand, without replacing the entire CPU heat sink 6, which greatly saves the user's economic expenses. Although the main chassis is small in size, it cleverly utilizes the metal casing of the main box to quickly transfer part of the CPU heat to the casing for dispersion. The heat greatly increases the effective area of heat dissipation.
Since the buckle 5 bracket adopts the movable fixed design in many places, it is almost compatible with all common motherboard models, the buckle 5 has few accessories and light weight, and the disassembly and assembly operation is extremely convenient, and the disassembly and assembly can be completed in 10 seconds.
Moreover, the bottom 12 of the ultra-thin PC main box casing has an elongated strip-shaped air inlet opening, which increases the airflow exchange around the bottom of the main box; and because of this long opening, the front of the partition 3 is greatly hindered. The heat on the floor area of the main box in the space is transferred to the main board floor area of the back space of the partition 3 and the partition 3 itself, so that the CPU attached to the main board bottom plate installed in the front space of the partition 3 is additionally cooled. The heat transferred by the device 64 can be taken away by the airflow more quickly, and is not transmitted to other parts of the mainframe to affect the heat dissipation of other hardware.
06) inner wall expansion socket 205
The mainframe of the main board 4 is placed near the north end of the main board 4, and the south end of the main board 4 is upward. The inner wall of the main casing of the main board 4 is located at the top of the main box. In the elongated area of the inner wall which is vertically 15~45 mm higher than the front surface of the main board 4, a long strip-shaped socket is movably mounted to constitute an inner wall expansion socket 205 of the main box, and the inner wall expansion socket 205 It includes three interfaces, DC+5V, DC negative power supply interface, 7+6pin SATA optical drive 204 interface and 7+15pin SATA hard disk interface.
The inner wall expansion socket 205 adopts a long strip PCB circuit board to concentrate the wires, the long strip PCB circuit board closely fits the inner wall of the main box, the circuit board portion extends to the edge of the front surface of the partition plate 3, and the long strip PCB circuit board extends Part of the circuit and the partition 3 The corresponding circuits are connected in a pair and are fixed by welding. The pins on the bottom of the interface socket are fixed on the corresponding circuit of the long PCB circuit board by soldering or contact action, and the orientation of the socket interface is parallel to the surface of the partition 3.
Considering the computer hardware of the optical disk drive 204, most users use the frequency very low, so the user-friendly "inner wall expansion socket 205" is designed to be movable and installed, and the user can select whether to install according to his own use requirements. .
When the thin optical disc drive 204 or the 2.5-inch hard disc 202 is inserted into the inner wall expansion socket 205, the thin optical disc drive 204 or the 2.5-inch hard disc 202 is parallel to the main board 4 and is located above the south end side of the main board 4. In view of practicality, the inlet port of the thin optical disk drive 204 faces the front of the main chassis. Cleverly and efficiently utilizes the free space above the south end of the motherboard 4, since the thin optical disc drive 204 and the 2.5-inch hard disc 202 are very light and low in heat generation, the influence on the center of gravity and heat dissipation of the entire main chassis is almost negligible. . In addition, since the motherboard 4 has a plurality of pins, slots and wires on the south end side, which affects the appearance, the thin optical disk drive 204 and the 2.5-inch hard disk 202 which are installed in parallel at the position of the motherboard 4 can be subtly blocked. To make the overall configuration of the mainframe more beautiful.
07) Motherboard I/O bezel partition card slot 16
A board I/O baffle partition card slot 16 is disposed at a position where an edge portion of the motherboard 4 on which the I/O interface group is located on the west end of the motherboard 4 is projected onto the partition 3, and the card slot is opened. a straight groove/hole slit with a slit width of about 1 mm and a seam depth of 2 to 3 mm, the total length of the slot/opening The total length of the motherboard I/O bezel 208 (the motherboard 4 tailgate), before the motherboard 4 is loaded into the main chassis, the motherboard I / O bezel 208 (the motherboard 4 back panel) A long side snaps into the groove/hole of the partition 3, and then the entire motherboard I/O baffle 208 (the main board 4 tailgate) is snapped into the main board I/O baffle at the rear of the main box. The 208 (main board 4 tailgate) is fixed in the matching opening. Since the main box adopts the ultra-thin design concept, in order to minimize the space required for the main board 4 in the main box, the main board I/O baffle 208 (the main board 4 tailgate) The side near the back of the motherboard 4 is snapped into the slot of the partition 3 and is mounted in a manner as simple as a conventional mainframe.
The hardware installed in the space on the back side of the partition 3 includes a separate display card 7 including a heat sink, a power supply box 9, a turbo fan 201, a hard disk 203, and a power distribution module 10, and are all mounted in parallel on the partition 3, Since the plurality of hard bodies mounted on the back surface of the partition plate 3 have a certain requirement for heat dissipation, the back surface of the partition plate 3 is not only matched with the power supply box 9, the bulkhead socket, and the power distribution module 10, and the concave partition circuit is matched. In addition to the 32 contact points, the surface of the other areas on the back side of the separator 3 is presented as a flat, thermally conductive metal plate. The specific structure is as follows:
08) Independent display card 7
The independent display card 7 is disposed in parallel with the back surface of the partition 3. This ultra-thin computer mainframe can be installed to support all full-height, half-height, ultra-long, high-power independent display cards7. The I/O interface on the independent display card 7 is oriented in the same direction as the I/O interface on the motherboard 4, and the I/O interface area on the independent display card 7 is offset from the edge portion of the motherboard 4 PCB, and the motherboard 4 PCB board The edge is the edge portion of the PCB that is provided with the 1/O interface, that is, the west end edge of the motherboard 4. The above-mentioned "I/O interface on the independent display card 7" is the "independent display card I/O interface group 71" in the figure, and the above-mentioned "I/O on the motherboard 4" The interface is the "master board I/O interface group 41" in the figure.
The parallel display of the independent display card 7 on the back of the motherboard 4 includes the following two forms:
1 Internal dispersion type: There is a parallel heat-conducting material partition plate 3 between the independent display card 7 and the motherboard 4, and the side of the independent display card 7 with the heat sink is opposite to the surface of the partition plate 3, and the independent display card 7 The PCB surface is close to the side panel of the outer casing of the mainframe, that is, one side of the sliding cover 2 in FIG. The "PCB board of the independent display card 7" is the "independent display card PCB board 70" in the figure. The end side of the PCB board on which the I/O interface group 71 on the independent display card 7 is located is oriented in the direction in which the I/O interface faces, and the end of the PCB board where the I/O interface group on the motherboard 4 is located The distance is 15~40mm. The motherboard board 4 and the PCB board of the independent display card 7 are arranged in parallel and close to each other, which greatly reduces the occupied space volume.
Specifically, there is a metal plate between the independent display card 7 and the motherboard 4, that is, the one side of the metal plate is mounted in parallel with the main board 4, the back side of the main board 4 is opposite to the metal flat plate, and the other side of the metal flat plate is installed in parallel. The independent display card 7 has a facing metal plate of the GPU chip 72 on the independent display card 7, and the independent display card 7 is placed in parallel on the back side of the motherboard 4 near the south end region.
As described above, the 7I/O interface of the independent display card is aligned with the interface of the motherboard 4I/O, and in the direction in which their I/O interfaces are oriented, the edge of the PCB where the independent display card 7I/O interface is located protrudes from the host. The distance between the edge of the PCB board where the 4I/O interface is located is 15~40 mm, that is, the I/O interface area on the independent display card 7 is translated to the west end of the motherboard 4. And the above-mentioned independent display protruding from the west end of the motherboard 4 There is no partition 3 between the portion of the card 7I/O interface area and the motherboard 4. Since the I/O interface of the high-end independent display card 7 is mostly double-layered, it is ingenious to separate the display card 7 in consideration of being fully compatible with all the display cards and minimizing the space occupied by the display card. The I/O interface area is partially translated out of the west end of the motherboard 4. In addition, there is no barrier between the 7I/O interface area of the independent display card and the motherboard 4, so that the I/O interface of the independent display card 7 is single-layer or double-layer, which does not affect the main chassis. The internal installation is as good as the traditional mainframe. The independent display card 7 communicates with the corresponding display card slot 43 on the motherboard 4 via a riser card or extension cable.
2 External type: The side (back side) on which the heat sink cannot be mounted on the independent display card PCB board 70 faces the back of the motherboard 4, and the partition board 3 does not necessarily exist between the motherboard 4 and the independent display card 7, and the independent display card 7I/O The edge of the PCB where the interface is located does not have to protrude from the edge of the PCB where the 4I/O interface of the motherboard is located. The independent display card 7 communicates with a corresponding display card slot on the motherboard 4 through a riser card or an extension cable. The motherboard 4 and the independent display card 7 are arranged in parallel and close to each other, which greatly reduces the occupied space volume. The biggest advantage of this method is that the heat sink and the fan 201 of the independent display card 7 need not be modified, and the original heat sink and the fan 201 of the independent display card 7 can be used, and the compatibility is good in this manner. The disadvantage is that the required mainframe space is larger than the "internal dispersion".
09) Internal scattered independent display card cooler 8
The heat sink mounted on the independent display card 7 is provided with a vacuum heat pipe 82 and a heat conducting base 81. The vacuum heat pipe has an evaporation end and a condensation end, and all of the heat sinks The evaporation end of the vacuum heat pipe is directly or indirectly in contact with the GPU chip 72 of the independent display card 7, and the condensation end of some or all of the vacuum heat pipes is in direct or indirect contact with the partition 3 or the inner wall of the metal casing of the main box. The "host box metal casing" is the "main box casing 1" in the figure.
The above-mentioned independent display card heat sink 8 is a flat heat sink as a whole, and has a small occupying volume. The utility model comprises aluminum or copper heat dissipation fins 83 arranged in parallel intervals, 2 to 8 vacuum heat pipes and 1 to 2 heat conduction bases. The aluminum or copper heat sink fins form a main portion of the flat heat sink, and the flat heat sink is mounted in parallel on the independent display card 7 or on the back surface of the partition plate 3. The heat conductive base is disposed on the front surface of the heat sink, and the back surface of the heat sink The flattened condensation end of the vacuum heat pipe is arranged on the surface, and the evaporation end of the vacuum heat pipe is in close contact with the copper or aluminum heat conductive base. The condensing end of the vacuum heat pipe is extruded through a die into a semi-arc or flat shape in cross section, and is closely attached to the fin, and the condensing end of the semi-arc/flat vacuum heat pipe on the back surface of the heat sink is also in parallel Conductive heat is applied to the back of the board 3.
Or the above flat heat sink further comprises arranged vacuum heat pipes, each vacuum heat pipe has an evaporation end and a condensation end, and the evaporation ends of all the vacuum heat pipes are closely attached or embedded in the heat conductive base. The condensing end of the vacuum heat pipe is extruded through a die into a "D" shape in cross section, that is, a flat side is formed at the condensation end of the vacuum heat pipe, and the flat side is parallel to the back surface of the heat sink. The non-flat side portion formed by the condensing end of the "D" shaped vacuum heat pipe is fixed to the back surface of the heat sink in combination with the heat dissipating fin of the heat sink. When the back surface of the flat heat sink is mounted in parallel or in contact with the partition surface, The flat side of the condensing end of the "D" shaped vacuum heat pipe will be placed in parallel on the face of the separator for heat conduction.
Since the heat sink is intimately in contact with the inner wall of the partition 3 or the metal casing of the main casing through the condensation section of the vacuum heat pipe, and the display card radiator fan 201 is not mounted on the radiator, there is no additional heat sink. The volume, so greatly increases the actual heat dissipation area of the independent display card 7. Moreover, the separator 3 for heat dissipation and the metal casing of the main box itself exist, and the material cost and the quality of the display card radiator are also greatly saved.

The backs of the partitions 3 are in parallel contact. Then, the GPU chip 72 of the independent display card 7 is vertically projected to the center of the back surface of the PCB of the display card, and the matching insulating elastic rubber pad 206 is pasted/mounted. When the main box cover is pushed through the chute in the main box, the The spacing between the cover plate and the PCB board of the independent display card 7 is smaller than the size of the elastic silicone pad 206. After the elastic silicone pad 206 is squeezed, a rebound pressure is generated to vertically act on the back surface of the independent display card PCB board 70. also Since the display card heat sink and the individual display card PCB board 70 are fixed, this generated pressure finally causes the display card heat sink to adhere to the surface of the spacer 3. A part of the heat reaching the display card heat sink is efficiently conducted to the partition 3 for heat dissipation.
Fixed type: the display card heat sink is firstly mounted in parallel on the corresponding partition 3 position of the back space of the main box, at this time, the "condensing section" of the vacuum heat pipe 82 in the heat sink and the surface of the partition 3 or the metal shell of the main box The inner walls are in close contact. Then, a matching insulating elastic silicone pad 206 is pasted/mounted on the vacant independent display card 7 GPU wafer 72 vertically projected to the center of the back surface of the display card PCB.

After the main box cover is pushed through the sliding slot in the main box, the spacing between the cover and the PCB of the independent display card 7 is smaller than the size of the elastic silicone pad 206, and the elastic silicone pad 206 is squeezed. The rebound pressure acts vertically on the back of the individual display card PCB board 70. After the center of the back surface of the GPU chip 72 on the independent display card 7 is pressed perpendicularly to the direction of the spacer 3, the surface of the GPU chip 72 is in parallel with the front surface of the display card heatsink base 81.
The stand-alone display card 7 is historically quick and easy to install with a fixed display card heatsink, and is installed in almost one second. Since the GPU chip 72 is subjected to the center position of the back, the surface of the GPU chip 72 can be smoothly attached to the surface of the heat-conducting base 81 of the display card heat sink, so that the force between the GPU chip 72 and the heat-conductive base 81 is naturally balanced. No longer have to worry about installing a traditional radiator. The screws are not balanced and affect the heat conduction effect.

The main board support column 31 type temperature probe 37, since the desktop computer does not necessarily have a separate display card 7, and the temperature of the CPU can more objectively reflect the change of the whole machine temperature, so it is necessary to be in the CPU A temperature probe 37 is placed near the radiator 6.
There is a motherboard mounting hole 47 between the PCI-E slot on the motherboard 4 and the memory strip slot 44. The mounting hole is correspondingly connected to the corresponding motherboard support post 31 on the partition 3.

It is no longer necessary to consider whether the fan 201 has a PWM function, nor does it need to enter the motherboard 4BISS to open and set, and the heat dissipation and noise can be obtained. Perfect dynamic balance.
14) Cooling air duct
The mainframe of the computer is provided with a suction-type cooling air duct, and the cooling method adopts an exhaust-type air-cooling heat dissipation, wherein the turbo fan 201 for exhausting air outside the main box is installed at the tail portion 13 of the main box, and the whole machine has two large The main air inlet and two small auxiliary air inlets, the two large main air inlets are the CPU air inlet 22 and the display card air inlet 23, and the two small auxiliary air inlets are the bottom air inlet 15 and the side air inlet.
The CPU air inlet 22 is located on the right side panel of the main unit casing, and has a large opening near the CPU heat sink 6; the display card air inlet 23 is located at the front of the main unit casing, corresponding to the area of the main box in which the independent display card 7 is mounted. There is a large elongated opening in the position; the bottom air inlet 15 is located on the bottom casing of the main box, and the partition 3 in the main box and the main board 4 extend perpendicularly to the two intersecting lines on the bottom plate of the main box. There is a slender opening; the side top air inlet has a small elongated opening at a position on the left side of the main casing casing near the top 11 and the front of the main casing.
In the air suction type air duct, except for the above four air inlet openings and the optical disc machine 204 into the disc opening 24, there is no other air inlet hole, and the fan 201 in the tail of the main unit box keeps the inside of the box. The air is pumped to the outside of the box, causing the air pressure in the box to be lower than the atmospheric pressure outside the box, forcing the air outside the box to flow through the air inlets into the box. Usually, when the rapid airflow generated by the air blowing form encounters the real object, the air pressure on the surface of the object will rise, and the air pressure will increase to the heat state, which is not conducive to the heat exchange between the surface of the object and the air of the airflow; The air pressure on the surface of the air duct slightly decreases, and the low-pressure air will more absorb the heat and expand its volume, which is beneficial to the heat exchange between the surface of the object and the air of the air.
The cold air flowing in from the CPU inlet 22 flows through the corresponding CPU radiator 6, and the cold air becomes a heat flow after absorbing the heat. Since the main chassis is vertical, the CPU heat sink 6 is in the lower half and the turbo fan 201 is in the upper half. The higher temperature heat flow flows to the top of the main box due to its natural lift and the suction of the turbo fan 201, and the lower temperature part of the heat flow is absorbed by the turbo fan 201 on the back side of the partition 3, through the edge of the partition 3 and the front panel 21 of the sliding cover. The gap between the walls flows into the lower half of the space on the back of the partition 3. Since the lower half of the back surface of the partition 3 is a power supply box 9 or a hard disk 203 which is mounted in parallel, the heat flow flowing therethrough can absorb the heat generated by the power supply box 9 and the hard disk 203.
The cold air flowing into the air inlet 23 of the display card directly flows through the corresponding independent display card heat sink 8, the upper half of the back surface of the partition 3, and the top of the main box in the back space of the partition 3. The intermediate position of the back surface of the partition 3, that is, the lower side of the mounting area of the independent display card 7, is provided between the position of the air inlet 23 of the display card and the turbo fan 201 at the back of the partition 3. A display card windshield 39 is placed, and the display card windshield 39 is simultaneously sealed against the back surface of the partition 3 and the inner wall of the sliding cover 2. The cold air of the air inlet 23 of the display card is simply and efficiently drained through the heat sink of the independent display card 7 to absorb heat, and finally extracted by the turbo fan 201, and the air passage is not interfered with by the heat flow in other spaces in the main box.
Since the vent hole 38 is opened in the central portion of the partition 3, the turbo fan 201 is attached to the vent hole 38 on the back surface of the partition 3. The cold air flowing in the bottom air inlet 15 flows through the lower half of the front surface of the partition 3 and the lower half of the back surface of the main board 4. Since the lower half of the back surface of the partition plate 3 is a power supply box 9 or a hard disk 203 which is mounted in parallel, a part of the heat generation is transmitted to the lower half of the partition plate 3, and the cold air which flows in from the air inlet 15 of the tank bottom is taken away by the cold air; The other part of the heat is mainly transferred to the tail and the bottom of the metal casing of the main box for heat dissipation; and a part of the heat is absorbed by the lower temperature heat flow remaining after the CPU air inlet 22 flows as described above.
Considering that the high-power independent display card 7 generates a large amount of heat, and the air volume of the air inlet 23 of the display card is limited, a side air inlet is also added, and the inflowing cold air mainly absorbs the area of the main box in the space behind the partition 3 and The heat of the upper end region of the small portion of the partition 3 is small. The cold air flowing in the four air inlets is heat-exchanged with the heat sinks of the radiators, the partitions 3, the heat generating hardware, and the metal casing of the main casing, and then becomes air heat flow, and is installed in the upper half and the tail of the main box. The turbofans 201 are exhausted from the outside of the tank.
In addition to several air inlets, the sealed design of the whole machine, together with the hardware configuration in the main box, is scientific and concise, and the generated wind resistance is small. In addition, the ultra-thin PC mainframe is small in size, and the air pressure difference generated in the box is in the form of ventilation. It is more obvious than the large main box, and the air duct formed in the main box has a large flow rate and a high wind speed. Moreover, the air passage formed by the low pressure generated by the suction, together with the scientific arrangement of the hardware, is simple, the wind resistance is small, and the air in the air passage flows in an orderly manner, and the phenomenon of returning hot air does not occur.
An air filter 25 is arranged on the four air inlet openings to filter dust entering the air in the box, so that the main box is kept clean and has good ventilation and heat dissipation performance for a long time.
