Description

Technical Field

[0001] The utility model relates to the technical field of liquid-cooled chassis, in particular to a liquid-cooled chassis for composite welding. Background Art

[0002] Composite welding may refer to the manufacture of a chassis by combining multiple welding methods or materials. A liquid-cooled chassis uses an internal liquid-cooling system to absorb and dissipate the heat generated inside the chassis through the circulating flow of liquid, thereby achieving the purpose of cooling. Such a chassis usually has high heat dissipation performance and can effectively meet the heat dissipation requirements of high-density and high-power devices.

[0003] In the existing composite welding liquid-cooled chassis, its internal structure includes components such as a coolant circulation pump, a radiator, and a cooling plate. After cooling the coolant, the coolant is transported to high-heat-generating parts inside the chassis for cooling, and finally flows into the cooling tank to cool the coolant again for recycling.

[0004] However, during the long-term operation of the composite welding device, due to the rapid temperature rise of the internal parts, the cooling of the coolant by the cooling plate in the liquid-cooling tank is slightly weak, and it is unable to cool the coolant to an appropriate temperature. Moreover, contacting the cooling plate with the coolant at too high a temperature will affect the service life of the cooling plate. It is necessary to pre-cool the coolant, and the cooling device is prone to damage during long-term use. If a more cooling device is needed, it is not convenient enough to disassemble the whole device. Summary of the Utility Model

[0005] In view of the problems of low cooling efficiency of the coolant and inconvenient replacement and installation of the cooling device, the present utility model is proposed.

[0006] To solve the above technical problems, the present utility model provides the following technical solution: A liquid-cooled chassis for composite welding, including a chassis shell. A cooling tank is provided at the bottom of the inner cavity of the chassis shell. A cooling plate is installed at the bottom of the inner cavity of the cooling tank. A liquid accumulation tank is provided at the upper end of the cooling tank. A liquid infusion pipe penetrating the chassis shell is communicated with the upper end of the liquid accumulation tank. A slidable air delivery shell is inserted between the cooling tank and the liquid accumulation tank. Air inlet channels are respectively formed through both sides of the air delivery shell. Removable cooling fans are installed inside the air inlet channels.

[0007] Cooling pipes are respectively arranged on one side of each cooling fan. The upper and lower ends of the cooling pipes are respectively communicated with the cooling tank and the liquid accumulation tank. L-shaped movable rods are respectively movably connected to one side of the cooling tank and the liquid accumulation tank. A connecting block that can be inserted into the upper end of the cooling fan is installed at one end of each L-shaped movable rod.

[0008] Preferably, a retaining piece is provided at the lower end of the L-shaped movable rod. A first spring is provided between the retaining piece and the cooling tank. Positioning holes into which the connecting blocks can be inserted are formed on the cooling fans.

[0009] Preferably, exhaust covers are installed on both sides of the box shell. One side of the exhaust cover is attached to the air inlet of the air inlet duct. A handle is installed at the upper end of the box shell, and a sealing cover is installed at the upper end of the infusion tube.

[0010] Preferably, a movable shell is installed on the inner side wall of the box shell. A telescopic block is slidably connected to the movable shell. A support frame is installed on the inner side wall of the movable shell. A cylinder is screwed to the support frame, and the output end of the cylinder is in contact with and installed on the telescopic block.

[0011] Preferably, an infusion pump is installed at the bottom of the inner cavity of the box shell. Flow guide pipes are installed at both the input end and the output end of the infusion pump. Both ends of the flow guide pipe are communicated with the cooling box and the liquid accumulation box. Support blocks are installed at the lower end of the box shell.

[0012] Preferably, a detachable air inlet cover is installed on one side of the box shell. One side of the air inlet cover is movably connected to a telescopic rod that abuts against the air delivery shell. A second spring is installed at the connection between the telescopic rod and the air inlet cover.

[0013] Advantages of the utility model:

[0014] 1. The coolant flows into the cooling box through the heat dissipation pipe connected to the lower end of the liquid accumulation box, so that the cooling fan extracts air from the air inlet of the air delivery shell to take away the heat on the surface of the heat dissipation pipe, thereby cooling the coolant. Then the coolant flows into the cooling box. By pulling out the L-shaped movable rod outwards, the box shell sleeved by it shrinks, so that the connecting block is pulled out of the positioning hole on the cooling fan, and the cooling fan can be directly taken out. At the same time, through the restoring force of the first spring, the connecting block can be inserted back into the positioning hole to install and fix the cooling fan. This mechanism enables pre-treatment and cooling of the coolant before it enters the cooling box, so that the cooling plate will not be damaged due to long-term contact with coolant at too high a temperature, and the cooling efficiency is improved;

[0015] 2. The cylinder on the support frame moves the telescopic block forward, and the connected air delivery shell will be pushed out together. When the air delivery shell is pushed away between the cooling box and the liquid accumulation box, the air delivery shell can be taken out, so as to replace the cooling fan. At the same time, when the air delivery shell is installed between the cooling box and the liquid accumulation box, the cylinder can be started to drive the telescopic block to retract into the movable shell. Then the air delivery shell is pushed into the chute between the liquid accumulation box and the cooling box. By making the telescopic rod abut against the air delivery shell, the restoring force of the second spring will abut against the air delivery shell through the telescopic rod, so that the air delivery shell cannot move to both sides. This mechanism makes the air delivery shell easy to install and take out, and will not move to both sides after installation, increasing the stability. Description of the drawings

Detailed implementation manners

[0026] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present utility model in conjunction with the drawings of the specification.

[0027] Embodiment 1

[0028] Refer to Figures 1-3, which is the first embodiment of the present utility model, provides a liquid-cooled chassis for composite welding, including a box shell 1. The box shell 1 is a protective shell and facilitates the installation of subsequent mechanisms. A handle 2 is installed at the upper end of the box shell 1. The handle 2 is used to assist in handling, and the box shell 1 can be lifted by holding the handle 2. A cooling box 3 is provided at the bottom of the inner cavity of the box shell 1. A cooling plate 6 is installed at the bottom of the inner cavity of the cooling box 3. The cooling box 3 is used to store the heated coolant and reduce its own temperature through heat conversion by the cooling plate 6, thereby cooling the coolant inside the cooling box 3. An accumulation box 4 is provided at the upper end of the cooling box 3. The accumulation box 4 has upper and lower cavities. The upper cavity of the accumulation box 4 is used to convey the cooled coolant to the composite welding box. At the same time, when the coolant is used up, it will flow back to the lower cavity of the accumulation box 4. A liquid infusion pipe 5 penetrating the box shell 1 is connected to the upper end of the accumulation box 4. A sealing cover is installed at the upper end of the liquid infusion pipe 5. The coolant can be replenished to the accumulation box 4 through the liquid infusion pipe 5 by opening the sealing cover. A slidable air delivery shell 7 is inserted between the cooling box 3 and the accumulation box 4. One end of the air delivery shell 7 is an installation groove, and the other end has a ventilation port. Air inlet channels 8 are respectively provided through both sides of the air delivery shell 7. Removable cooling fans 9 are installed inside the air inlet channels 8. The air delivery shell 7 is communicated with the air inlet channels 8. At the same time, air can be drawn through the ventilation port of the air delivery shell 7 by the cooling fans 9;

[0029] Radiating pipes 14 are respectively provided on one side of each cooling fan 9. The multi-curved shape of the radiating pipes 14 increases the flowing path of the coolant inside the radiating pipes 14. Moreover, the radiating pipes 14 are made of heat-dissipating materials. When the coolant flows inside, heat of the coolant will be released on the surface of the radiating pipes 14. At the same time, the heat on the surface of the radiating pipes 14 can be blown away by the airflow through the blowing of the cooling fans 9, realizing indirect cooling of the coolant. The upper and lower ends of the radiating pipes 14 are respectively communicated with the cooling box 3 and the accumulation box 4. After the coolant is cooled by the cooling fans 9, it will flow into the cooling box 3. L-shaped movable rods 10 are movably connected to one side of each of the cooling box 3 and the accumulation box 4. One end of each L-shaped movable rod 10 is installed with a connecting block 13 that can be inserted into the upper end of the cooling fan 9. The cooling fan 9 can be fixed by inserting the connecting block 13 into the cooling fan 9, realizing quick installation and replacement of the cooling fan 9.

[0030] A retaining piece is provided at the lower end of the L-shaped movable rod 10. A first spring 11 is provided between the retaining piece and the cooling box 3. Positioning holes 12 into which the connecting block 13 can be inserted are provided on the cooling fan 9. The L-shaped movable rod 10 can be pushed by the first spring 11 to retract, driving the connecting block 13 to insert into the positioning holes 12 to install and fix the cooling fan 9.

[0031] Exhaust covers 15 are installed on both sides of the box shell 1. A large number of vertical strip-shaped air outlet openings are provided on the surface of the exhaust covers 15. One side of the exhaust cover 15 is in fit with the air outlet of the air inlet channel 8. When the cooling fans 9 blow away the heat on the surface of the radiating pipes 14, the hot air blown out by the cooling fans 9 at this time will be discharged through the air outlet openings on the exhaust covers 15.

[0032] In use, the sealing cap at the upper end of the infusion tube 5 can be unscrewed first, and the coolant is added to the inside of the liquid accumulation tank 4. Then, when the internal parts of the composite welding box need to be cooled, the coolant in the upper cavity of the liquid accumulation tank 4 will be transmitted for cooling. After that, the used coolant will flow into the lower cavity of the liquid accumulation tank 4, and then flow into the cooling box 3 through the heat dissipation pipe 14 connected to the lower end of the liquid accumulation tank 4. When flowing into the inside of the heat dissipation pipe 14, since the heat dissipation pipe 14 is in a multi-curve bending shape, it increases the flowing path of the coolant in the heat dissipation pipe 14 and also increases the surface area of the heat dissipation pipe 14. At this time, by starting the heat dissipation fan 9, the heat dissipation fan 9 extracts air from the air inlet of the air delivery shell 7 to blow the surface of the heat dissipation pipe 14, and takes away the heat on the surface of the heat dissipation pipe 14 through the air, thereby indirectly cooling the coolant inside the heat dissipation pipe 14. Finally, the coolant flows into the cooling box 3, and the heat conversion through the cooling plate 6 reduces its own temperature, thereby cooling the coolant inside the cooling box 3;

[0033] When the heat dissipation fan 9 is damaged, the L-shaped movable rod 10 can be pulled outwards, so that the box shell 1 sleeved on it shrinks, and then the connecting block 13 is pulled out of the positioning hole 12 on the heat dissipation fan 9. At this time, the heat dissipation fan 9 can be directly taken out. When the heat dissipation fan 9 needs to be installed, the connecting block 13 can be inserted back into the positioning hole 12 through the restoring force of the first spring 11, and then the heat dissipation fan 9 can be installed and fixed again. This mechanism enables pre-treatment and cooling of the coolant before it enters the cooling box 3, preventing the cooling plate 6 from being damaged due to long-term contact with coolant at too high a temperature, and improving the cooling efficiency.

[0034] Embodiment 2

[0035] Referring to Figures 1-7 , this is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that a movable shell 18 is installed on the inner side wall of the box shell 1. A telescopic block 19 is slidably connected to the movable shell 18. One end of the telescopic block 19 away from the movable shell 18 can be inserted into the installation groove of the air delivery shell 7. At the same time, the telescopic block 19 can push the air delivery shell 7, so that the air delivery shell 7 moves between the cooling box 3 and the liquid accumulation tank 4. A support frame 20 is installed on the inner side wall of the movable shell 18. A cylinder 21 is screwed on the support frame 20. The support frame 20 is used to support the cylinder 21 and can be disassembled. The output end of the cylinder 21 is in contact with the telescopic block 19. The telescopic block 19 can be driven by the cylinder 21 to move inside the movable shell 18, so as to push the air delivery shell 7 away from between the cooling box 3 and the liquid accumulation tank 4 through the telescopic block 19.

[0036] Inside the bottom of the inner cavity of the box housing 1, an infusion pump 16 is installed. Both the input end and the output end of the infusion pump 16 are equipped with diversion pipes 17. The two ends of the diversion pipes 17 are connected to the cooling box 3 and the liquid accumulation box 4. The already cooled coolant inside the cooling box 3 can be transported to the upper cavity of the liquid accumulation box 4 through the infusion pump 16. At the lower end of the box housing 1, a support block 25 is installed. The support block 25 is made of rubber and has high-friction patterns at the bottom.

[0037] On one side of the box housing 1, a detachable air inlet cover 22 is installed. There are numerous vertical filter holes on the air inlet cover 22. The filtered air can be blown out by the cooling fan 9 through the inner cavity of the air delivery housing 7 through the air inlet cover 22. On one side of the air inlet cover 22, a telescopic rod 23 that abuts against the air delivery housing 7 is movably connected. At the connection of the telescopic rod 23 and the air inlet cover 22, a second spring 24 is installed. By pushing the telescopic rod 23 to coincide with and abut against the air delivery housing 7, the second spring 24 can be contracted. The air delivery housing 7 can be positioned between the telescopic block 19 and the air inlet cover 22 by the restoring force of the second spring 24 against the air delivery housing 7, preventing it from moving to both sides.

[0038] During use, when the cooling fan 9 is damaged and needs to be replaced, the staff first needs to remove the air inlet cover 22, and then push out the telescopic block 19 from inside the movable housing 18 through the cylinder 21 on the support frame 20. When the telescopic block 19 moves forward, the connected air delivery housing 7 will be pushed out together. When the air delivery housing 7 is pushed away from between the cooling box 3 and the liquid accumulation box 4, the staff can take out the air delivery housing 7, so as to replace the cooling fan 9. When the air delivery housing 7 needs to be reinstalled between the cooling box 3 and the liquid accumulation box 4, the cylinder 21 needs to be started first to drive the telescopic block 19 to retract into the movable housing 18. Then the staff can push the air delivery housing 7 into the chute between the liquid accumulation box 4 and the cooling box 3. When the air inlet cover 22 is about to contact the air delivery housing 7, the telescopic rod 23 will first abut against the air delivery housing 7. At this time, the second spring 24 at the end of the telescopic rod 23 will be compressed accordingly. When the air inlet cover 22 is installed and fixed, the restoring force of the second spring 24 will abut against the air delivery housing 7 through the telescopic rod 23, making the air delivery housing 7 unable to move to both sides. This mechanism makes the air delivery housing 7 easy to install and remove, and it will not move to both sides after installation, increasing the stability.

[0039] The remaining structures are the same as those in Embodiment 1.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
