Description

Technical Field

[0001] This utility model relates to the field of computer heat dissipation technology, specifically a computer heat dissipation case with a graphics card protection device. Background Technology

[0002] The main function of a computer case is to house and secure various computer components, providing support and protection. In addition, the computer case plays an important role in shielding electromagnetic radiation. During long-term operation and use, heat dissipation is crucial, especially when processing large amounts of data. Poor heat dissipation can cause the graphics card and CPU to overheat, leading to a decrease in computer performance.

[0003] Chinese patent CN219625930U discloses a computer cooling chassis. This device, through its cooling fan assembly and locking mechanism, can prevent the cooling fan from slowing down due to excessive dust accumulation on the fan blades during use, and also prevent dust from entering the motor and damaging it. This reduces the impact of dust on the cooling fan and improves the heat dissipation effect inside the computer chassis.

[0004] However, when the temperature inside the computer case is too high, in order to quickly cool down the computer and improve its performance, the cooling fan inside the case usually needs to work under load, thereby accelerating the cooling of the computer.

[0005] Since many internal components of the host are fixed by welding or precision bolts, long-term exposure to the vibration of the cooling fan may cause slight displacement of some mechanical connecting parts (such as graphics card mounting screws or CPU heatsink brackets). This phenomenon is more pronounced on graphics cards: the cooling fan on the graphics card is connected to the motherboard in a cantilevered structure, and the vibration energy it generates will be directly transmitted to the PC I e slot and mounting bracket. In addition, the graphics card is larger and heavier, making it more susceptible to the cumulative effect of vibration compared to the LGA package structure of the CPU. Utility Model Content

The output end of the micro-circulation pump is connected to the second hot liquid return pipe. A chassis cooling fan is installed on one side of each condenser pipe to cool it.

[0010] As a preferred embodiment of this utility model, the clamping structure includes a side protective frame fixed to one side of the mounting base, the side protective frame having a through groove, and a side frame installed on the outside of the side protective frame for lateral impact protection of the graphics card cooling fan; it also includes a fixing rod, the fixing rod being located between two opposite through grooves for limiting the heat sink; and a slider, the slider being slidably connected along the horizontal direction of the side frame, and a telescopic cylinder being installed on the slider, the telescopic end of the telescopic cylinder being fixedly connected to one end of one of the fixing rods, and the other end of the telescopic cylinder being fixedly connected to one end of the other fixing rod.

[0011] As a preferred embodiment of this utility model, guide rods are symmetrically fixed on the mounting base, and a first hinge seat is slidably mounted on the guide rod. The first hinge seat is fixedly connected to the damping rod and is hinged to the connecting rod. A spring is provided on the outer side of the guide rod between the first hinge seat and the mounting base to drive the damping rod to move away from the mounting base. A second hinge seat is provided on the outer side of the slider, and the second hinge seat is hinged to the other end of the connecting rod.

[0012] As a preferred technical solution of this utility model, a top chassis is installed at the upper end of the main body of the chassis. The top chassis is provided with a wind chamber for installing a condenser pipe. The wind chamber has a second ventilation window that runs through the main body of the chassis on one side. The chassis cooling fan is fixed between the second ventilation window and the condenser pipe. A guide fan blade is fixed at the lower end of the wind chamber. The guide fan blade is located above the graphics card cooling fan and is used to guide the airflow inside the wind chamber.

[0013] As a preferred embodiment of this utility model, the second hydrothermal reflux pipe is made of pure copper, the volatile solvent is one of ammonia, alcohol, methanol or acetone, and a sealing gasket is provided at the connection between the fixed sleeve and the second hydrothermal reflux pipe.

[0016] As a preferred technical solution of this utility model, an impact-resistant plate is installed on one side of the first side plate. The impact-resistant plate is a hollow plate made of steel, and a buffer pad is provided on the side of the impact-resistant plate facing the graphics card body.

[0017] Compared with the prior art, this utility model provides a computer heat dissipation case with a graphics card protection device, which has the following advantages:

[0018] 1. This computer cooling case with graphics card protection device uses a damping rod to move a connecting rod, adjusting the distance between the clamping structure and the mounting base. This facilitates fixing the other end of the heatsink. Heat exchange occurs between the heatsink and volatile solvents through the second hot liquid return pipe, causing the solvents to evaporate. This creates a pressure difference between the two sides of the annular piston, further causing the annular piston to move the movable sleeve and push the damping rod. This resists the reciprocating motion of the damping rod on the second hot liquid return pipe, thereby improving the stability of the graphics card body in the cantilever connection structure and preventing a decrease in structural stability caused by vibrations from the graphics card cooling fan itself.

[0019] 2. This computer cooling case with graphics card protection device cools the heatsink through heat pipes, thereby reducing the temperature of the heatsink and further increasing the temperature difference between the heatsink and the graphics card body. This facilitates the transfer of heat energy from the graphics card body to the heatsink, accelerating the cooling of the graphics card body. The condenser pipes cool the heated refrigerant and then re-introduce the refrigerant into the heat pipes, realizing the circulation of the refrigerant. Attached Figure Description

[0030] 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.

[0031] Please see Figure 1 - Figure 9 This utility model discloses a computer heat dissipation case with a graphics card protection device, including a main chassis, a mounting base 5 installed on the main chassis, and a graphics card body 12 with a graphics card cooling fan 11. It also includes a heat sink 27, which is located below the graphics card body 12 and one end of it is fixedly connected to the mounting base 5. Preferably, thermal grease is filled between the heat sink 27 and the graphics card body 12 to facilitate the transfer of heat when the graphics card body 12 is working. In addition, the heat sink 27 and the mounting base 5 can be connected by bolts or clips to make the graphics card body 12 and the main chassis have a cantilever connection structure, which conforms to the existing graphics card body 12 installation and expands the applicability of this solution.

[0032] To improve the heat dissipation of the graphics card body 12, the computer cooling case with graphics card protection device provided in this embodiment also includes a heat pipe 30 and a condenser pipe 25. The heat pipe 30 symmetrically penetrates the heat sink 27 in a horizontal direction, and the condenser pipe 25 is symmetrically arranged inside the case body and filled with refrigerant. A second hot liquid return pipe 32 is provided between the condenser pipe 25 and the heat pipe 30 for the refrigerant inside the heat pipe 30 to return to the condenser pipe 25. Specifically, the heat pipe 30 cools the heat sink 27, thereby reducing the temperature of the heat sink 27 and further increasing the temperature difference between the heat sink 27 and the graphics card body 12. This facilitates the transfer of heat energy from the graphics card body 12 to the heat sink 27, thereby accelerating the cooling of the graphics card body 12. The condenser pipe 25 cools the heated refrigerant and re-introduces the refrigerant into the heat pipe 30 to achieve refrigerant circulation.

[0033] The computer cooling case with graphics card protection device provided in this embodiment also includes a clamping structure located at the end of the heat sink 27 away from the mounting base 5, thereby providing auxiliary fixation to the suspended end of the cantilever connection structure of the graphics card body 12 to improve the fixation effect of the graphics card body 12. The clamping structure can slide along the horizontal direction of the heat sink 27 to adjust the clamping effect of the clamping structure.

[0034] To adjust the position of the clamping structure, the computer heat sink housing with graphics card protection device provided in this embodiment also includes a damping rod 21. The damping rod 21 slides axially along the second hot liquid return pipe 32. Preferably, a sliding hole is opened in the middle section of the damping rod 21, and the sliding hole is slidably connected to the second hot liquid return pipe 32. Connecting rods 20 are rotatably connected to both ends of the damping rod 21. The other end of the connecting rod 20 is connected to the clamping structure shaft. The damping rod 21 is raised and lowered to drive the connecting rod 20 to move, thereby adjusting the angle between the connecting rod 20 and the horizontal plane. This further allows the clamping structure at the other end of the connecting rod 20 to move, so as to adjust the distance between the clamping structure and the mounting base 5, which is beneficial for fixing the other end of the heat sink 27.

[0035] To further improve the stability of the graphics card body 12 in the cantilever connection structure, the computer cooling case with graphics card protection device provided in this embodiment also includes a fixed sleeve 31. The fixed sleeve 31 is located outside the second hot liquid return pipe 32, and the surface of the fixed sleeve 31 is provided with a heat insulation layer. A movable sleeve 34 is installed inside the fixed sleeve 31. The movable sleeve 34 is slidably connected to the second hot liquid return pipe 32, and one end of the movable sleeve 34 is fixed to the damping rod 21. An annular piston 35 is slidably connected inside the fixed sleeve 31 and fixedly connected to the other end of the movable sleeve 34. A volatile solvent is injected inside the fixed sleeve 31 below the annular piston 35. Specifically, after the refrigerant is heated, it flows through the second hot liquid return pipe 32. During reflux, the second hot liquid reflux pipe 32 exchanges heat with the volatile solvent, causing the volatile solvent in the fixed sleeve 31 to heat up and evaporate. This creates a pressure difference between the spaces on both sides of the annular piston 35 inside the fixed sleeve 31. Under the action of the pressure difference, the annular piston 35 moves, which in turn drives the movable sleeve 34 to push the damping rod 21 away from the mounting base 5. This resists the reciprocating motion of the damping rod 21 on the second hot liquid reflux pipe 32, improving the stability of the damping rod 21. This, in turn, improves the stability of the graphics card body 12 in the cantilever connection structure, preventing a decrease in structural stability caused by vibrations generated by the graphics card cooling fan 11 mounted on the graphics card body 12.

[0036] like Figure 9 As shown, in order to further improve the heat exchange effect between the second hydrothermal reflux pipe 32 and the volatile solvent, a first heat insulation sleeve is provided on the outside of the second hydrothermal reflux pipe 32 to reduce the heat leakage of the second hydrothermal reflux pipe 32. A vertical heat-conducting groove 33 is provided on the surface of the second hydrothermal reflux pipe 32 at the position of the fixed sleeve 31 to accelerate the heat exchange between the second hydrothermal reflux pipe 32 and the volatile solvent, improve the heat exchange effect, and thus accelerate the evaporation efficiency of the volatile solvent.

[0037] like Figure 5 , Figure 7 and Figure 8 As shown, this embodiment provides two sets of heat dissipation pipes 30, and both sets of heat dissipation pipes 30 are in a zigzag shape to better improve the heat exchange effect between the radiator 27 and the heat dissipation pipes 30. A first hot liquid return pipe 29 connected to the second hot liquid return pipe 32 is installed at the output end of the heat dissipation pipe 30, and a cold liquid output pipe 28 is installed at the input end of the heat dissipation pipe 30. A second heat insulation sleeve is fitted on the outer surface of the cold liquid output pipe 28 to keep the refrigerant warm after it is output, so as to prevent the refrigerant from heating up due to heat exchange with the outside during the output process.

[0038] In addition, this embodiment provides two sets of condenser tubes 25, and both sets of condenser tubes 25 are in a zigzag shape. The output end of the condenser tube 25 is connected to the cold liquid output pipe 28, and a micro circulation pump 36 is installed at the input end of the condenser tube 25. The output end of the micro circulation pump 36 is connected to the second hot liquid return pipe 32. A chassis cooling fan 24 is installed on one side of the condenser tube 25. The chassis cooling fan 24 is used to cool the condenser tube 25.

[0039] Furthermore, after the refrigerant inside the heat sink 30 is heated, the heated refrigerant is circulated into the condenser 25 through the first hot liquid return pipe 29 and the second hot liquid return pipe 32 by the micro circulation pump 36. The airflow around the condenser 25 is accelerated by the chassis cooling fan 24, thereby accelerating the heat exchange effect between the condenser 25 and the outside world, which in turn cools down the refrigerant inside the condenser 25. The cooled refrigerant then flows into the heat sink 30 through the cold liquid output pipe 28, thus realizing the recycling of the refrigerant.

[0040] like Figure 3 - Figure 7 As shown, the clamping structure provided in this embodiment includes a side protection frame 15 fixed to one side of the mounting base 5. The side protection frame 15 is provided with a through groove 19, and a side frame 16 is installed on the outside of the side protection frame 15. The side frame 16 and the side protection frame 15 cooperate to form an inverted "T" shaped structure, which is beneficial for lateral impact protection of the graphics card cooling fan 11 and the graphics card body 12.

[0041] The clamping structure provided in this embodiment also includes a fixing rod 18, which is located between two opposite through slots 19 and is used to limit the position of the radiator 27. The two fixing rods 18 cooperate with each other to clamp one end of the radiator 27, thereby improving the stability of the cantilever structure away from the mounting base 5.

[0042] Furthermore, the clamping structure also includes a slider 17, which is slidably connected along the side frame 16 in the horizontal direction. A telescopic cylinder 26 is installed on the slider 17. The telescopic end of the telescopic cylinder 26 is fixedly connected to one end of one of the fixed rods 18, and the other end of the telescopic cylinder 26 is fixedly connected to one end of the other fixed rod 18. Preferably, the telescopic cylinder 26 includes a cylinder and a rod, wherein the lower end of the rod is inserted into the cylinder and a piston plate is installed. A compression spring is installed between the piston plate and the top of the cylinder, which facilitates the active adjustment of the distance between the two fixed rods 18 to accommodate the fixed clamping of radiators 27 of different specifications. It should be noted that the outer diameter of the fixed rod 18 is smaller than the width of the through groove 19, which facilitates the adjustment of the range of motion of the fixed rod 18.

[0043] like Figure 5 - Figure 7As shown, in order to achieve the linkage between the clamping structure and the damping rod 21, the mounting base 5 provided in this embodiment is symmetrically fixed with guide rods 22. A first hinge seat is slidably mounted on the guide rod 22. The first hinge seat is fixedly connected to the damping rod 21 and is hinged to the connecting rod 20. A spring 23 is provided on the outside of the guide rod 22 between the first hinge seat and the mounting base 5. The spring 23 is used to drive the damping rod 21 to move away from the mounting base 5. A second hinge seat is provided on the outside of the slider 17. The second hinge seat is hinged to the other end of the connecting rod 20.

[0044] In use, the damping rod 21 is driven by the spring 23, which causes the connecting rod 20 to pull the slider 17 toward the mounting base 5. This further causes the two fixed rods 18 to move toward the mounting base 5, thereby making the connection between the fixed rods 18 and the radiator 27 tighter, thus improving the stability of the other end of the radiator 27. Furthermore, a triangular structure is formed between the connecting rod 20, the guide rod 22, and the side protective frame 15 to improve the stability of the cantilever structure away from the mounting base 5.

[0045] like Figure 3 - Figure 6 As shown, the chassis body provided in this embodiment has a top chassis 10 installed at the upper end. The top chassis 10 has a wind chamber 14, which is used to install the condenser pipe 25. The wind chamber 14 has a second ventilation window 6 that runs through the chassis body on one side. Preferably, the second ventilation window 6 has a dustproof net on the outside. The chassis cooling fan 24 is fixed between the second ventilation window 6 and the condenser pipe 25. A guide fan blade 13 is fixed at the lower end of the wind chamber 14. The guide fan blade 13 is located above the graphics card cooling fan 11 and is used to guide the airflow inside the wind chamber 14.

[0046] Specifically, when the chassis cooling fan 24 is working, it accelerates the airflow inside the air chamber 14, thereby accelerating the cooling of the condenser pipe 25. The airflow is guided into the area above the graphics card cooling fan 11 by the guide fan blades 13. With the cooperation of the graphics card cooling fan 11, the heat dissipation effect of the graphics card body 12 is improved.

[0047] like Figure 9 As shown, the second hot liquid return pipe 32 provided in this embodiment is made of pure copper. Pure copper has good thermal conductivity, which is conducive to heat exchange between the refrigerant and the volatile solvent after heating. The volatile solvent is one of ammonia, alcohol, methanol or acetone. Through the repeated circulation, evaporation and condensation of the liquid inside the fixed sleeve 31, the pressure difference on both sides of the annular piston 35 is changed, thereby driving the annular piston 35 to slide. In order to improve the sealing effect of the fixed sleeve 31, a sealing gasket is provided at the connection between the fixed sleeve 31 and the second hot liquid return pipe 32.

[0048] like Figure 1 - Figure 4As shown, the chassis body provided in this embodiment includes two first side plates 1 arranged opposite to each other, a bottom plate 8 is installed between the bottoms of the two first side plates 1, and a top plate 3 is installed between the tops of the two first side plates 1. A second side plate 2 is symmetrically arranged between the top plate 3 and the bottom plate 8, wherein the first side plate 1 is connected to the bottom plate 8, the top plate 3 and the second side plate 2 by snap-fit ​​connection and / or bolt connection.

[0049] like Figure 1 - Figure 4 As shown, one of the second side panels 2 is provided with a third ventilation window 7, and the other second side panel 2 is provided with a first ventilation window 4, so as to accelerate the air flow inside the chassis body and thus accelerate the cooling inside the chassis body.

[0050] like Figure 3 As shown, in order to improve the impact resistance of the chassis body, an impact plate 9 is installed on one side of one of the first side panels 1. The impact plate 9 is a hollow steel plate, and a buffer pad is provided on the side of the impact plate 9 facing the graphics card body 12, thereby improving the impact resistance of the chassis body. Of course, the impact plate 9 and the buffer pad can also be installed on the inside of both first side panels 1.

[0051] The working principle and usage process of this utility model are as follows: In use, one end of the radiator 27 is fixed on the mounting base 5. By adjusting the position of the clamping structure, the two fixing rods 18 clamp the other end of the radiator 27. The damping rod 21 is moved by the spring 23, which causes the connecting rod 20 to pull the slider 17 towards the mounting base 5. This further causes the two fixing rods 18 to move towards the mounting base 5, thereby making the connection between the fixing rods 18 and the radiator 27 tighter and improving the stability of the other end of the radiator 27. The connecting rod 20, the guide rod 22 and the side protective frame 15 cooperate to form a triangular structure to improve the stability of the cantilever structure away from the mounting base 5.

[0052] When the graphics card body 12 is cooled, the heat generated on the graphics card body 12 is transferred to the heatsink 27 through thermal grease. The heatsink 27 is then cooled by the heat pipe 30, thereby reducing the temperature of the heatsink 27. This further increases the temperature difference between the heatsink 27 and the graphics card body 12, which facilitates the transfer of heat from the graphics card body 12 to the heatsink 27, thus accelerating the cooling of the graphics card body 12. After the refrigerant inside the heat pipe 30 is heated, the heated refrigerant is circulated into the condenser 25 through the first hot liquid return pipe 29 and the second hot liquid return pipe 32 by the micro circulation pump 36. The airflow around the condenser 25 is accelerated by the chassis cooling fan 24, thereby accelerating the heat exchange between the condenser 25 and the outside environment, which in turn cools the refrigerant inside the condenser 25. The cooled refrigerant then flows into the heatsink 30 through the coolant output pipe 28, thus realizing the recycling of the refrigerant.

[0053] During this process, when the refrigerant is heated and flows back through the second hot liquid return pipe 32, the second hot liquid return pipe 32 exchanges heat with the volatile solvent, thereby causing the volatile solvent in the fixed sleeve 31 to heat up and evaporate. This results in a pressure difference between the spaces on both sides of the annular piston 35 inside the fixed sleeve 31. Under the action of the pressure difference, the annular piston 35 moves, which in turn drives the movable sleeve 34 to push the damping rod 21 to move away from the mounting base 5. This resists the reciprocating motion of the damping rod 21 on the second hot liquid return pipe 32, improving the stability of the damping rod 21. This, in turn, improves the stability of the graphics card body 12 in the cantilever connection structure, and avoids the decrease in structural stability caused by the vibration generated by the graphics card cooling fan 11 mounted on the graphics card body 12.
