Description

Technical Field

[0001] This invention belongs to the field of computer-aided equipment technology, specifically referring to an external high-efficiency cooling device for computer hosts. Background Technology

[0002] When a desktop computer runs under high load for extended periods, its internal components, such as the CPU and graphics card, generate a significant amount of heat. Inadequate heat dissipation can lead to overheating, causing system lag, blue screens, and even hardware damage. Traditional cooling methods primarily rely on fans inside the computer case, but this is particularly problematic for older models, smaller cases, or high-power-consumption systems where poor airflow or insufficient cooling capacity is a significant issue.

[0003] Most existing computer cases are placed directly on desktops or ordinary stands, making them susceptible to tipping over due to impacts and difficult to move. Internal fans are limited by the internal space of the case, resulting in poor airflow and dead zones for heat dissipation, which can lead to hardware throttling under high temperatures. To prevent dust from entering the case, the air intake of the computer case usually has a filter, but the filter needs to be manually removed and cleaned after accumulating dust, which is cumbersome. If it is not cleaned for a long time, it will lead to a decrease in airflow and a significant reduction in cooling efficiency. When manually cleaning the filter, dust can easily fall onto the desktop or inside the case, causing secondary pollution and affecting the cleanliness of the indoor environment and the hardware itself. Therefore, there is an urgent need for a new type of external high-efficiency cooling device for computer cases to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an external high-efficiency cooling device for computer hosts that offers excellent cooling performance, rapidly reduces the internal temperature of the host, securely fixes the host to a mobile base using a clamping assembly to prevent displacement, automatically cleans the bottom protective filter using an automatic cleaning unit to prevent dust blockage, and boasts high cooling efficiency, strong host stability, and high safety.

[0005] The technical solution adopted by the present invention is as follows: The present invention is an external high-efficiency cooling device for computer hosts, comprising a movable base, a clamping assembly, and a cleaning assembly. The movable base is provided with a baffle above it, and a cooling chamber is provided inside the movable base. The top and bottom walls of the cooling chamber are provided with protective filters. The protective filter on the top wall of the cooling chamber penetrates through the top wall of the movable base. A cooling assembly is provided inside the cooling chamber. The clamping assembly is located above the movable base. The cleaning assembly is located inside the lower end of the movable base and below the cooling chamber. Two sets of negative pressure dust collection assemblies are provided at both ends of the movable base, and the two sets of negative pressure dust collection assemblies are symmetrically arranged on both sides of the cooling chamber.

[0006] Furthermore, the cooling component includes a semiconductor cooling chip, two sets of heat dissipation fins, and two sets of cooling fans. The semiconductor cooling chip is disposed inside the cooling cavity, the two sets of heat dissipation fins are respectively disposed at the cold end and the hot end of the semiconductor cooling chip, and the two sets of cooling fans are symmetrically disposed at the upper and lower ends of the cooling cavity and on one side of the heat dissipation fins.

[0007] Furthermore, the side walls of the enclosure are respectively provided with two clamping grooves and two clamping guide grooves. The clamping grooves and clamping guide grooves are symmetrically arranged on both sides of the enclosure, and the two clamping grooves and the two clamping guide grooves are symmetrically arranged at both ends of the enclosure.

[0008] Furthermore, the clamping assembly includes a clamping double-threaded rod, a clamping guide rod, and two clamping plates.

The clamping sliders are slidably disposed within the clamping grooves and clamping guide grooves. The clamping double-threaded rod is threadedly connected to the clamping slider in the clamping groove. The clamping guide rod passes through the clamping slider in the clamping guide groove. A clamping motor for driving the clamping double-threaded rod is fixed within the enclosure. The two clamping plates can move towards each other to clamp main units of different widths.

[0009] Furthermore, the cleaning assembly includes a cleaning chute, a cleaning guide chute, and a cleaning brush. The lower two side walls of the movable base are symmetrically provided with cleaning chute and cleaning guide chute. A cleaning screw is installed in the cleaning chute, and a cleaning guide rod is installed in the cleaning guide chute. The cleaning brush is slidably positioned below the cooling chamber. Cleaning sliders are symmetrically fixed at both ends of the cleaning brush. The cleaning sliders are slidably positioned within the cleaning chute and cleaning guide chute. The cleaning screw is threadedly connected to the cleaning slider in the cleaning chute. The cleaning guide rod passes through the cleaning slider in the cleaning guide chute. The movable base contains a cleaning motor that drives the cleaning screw, and its bristles contact the protective filter screen on the bottom wall of the movable base. The cleaning brush reciprocates along the surface of the bottom protective filter screen, thoroughly cleaning the dust accumulated on the filter screen surface.

[0010] Furthermore, the negative pressure dust collection assembly includes a negative pressure chamber, a negative pressure fan, a dust collection box, and a dust suction port.

[0013] The beneficial effects achieved by the present invention using the above structure are as follows:

[0014] 1. By combining semiconductor cooling chips to cool the internal components of the host, the heat exchange efficiency is improved, which can quickly reduce the internal ambient temperature of the host and effectively alleviate hardware throttling.

[0015] 2. The cleaning component, in conjunction with the negative pressure suction component, automatically cleans the bottom protective filter and immediately sucks in and collects the swept dust into the dust collection box, preventing secondary dust re-entrainment and maintaining a clean environment. No manual disassembly is required, improving dust removal efficiency.

[0016] 3. By using clamping components, host chassis of different widths can be fixed on the mobile base, preventing the host chassis from shifting and solving the problem of unstable fixation of traditional bases. Attached Figure Description

Two clamping guide grooves 13 and two clamping plates 16 are symmetrically slidably disposed above the movable base 1 and within the enclosure 4. The clamping plates 16 are symmetrically fixed with clamping sliders 17 at both ends. The clamping sliders 17 are slidably disposed within the clamping grooves 12 and the clamping guide grooves 13. The clamping double threaded rod 14 is threadedly connected to the clamping sliders 17 in the clamping grooves 12. The clamping guide rod 15 passes through the clamping sliders 17 in the clamping guide grooves 13. The enclosure 4 is fixed with a clamping motor 18 that drives the clamping double threaded rod 14.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, the cleaning assembly 3 includes a cleaning groove 19, a cleaning guide groove 20, and a cleaning brush 21. The cleaning groove 19 and the cleaning guide groove 20 are symmetrically arranged on both sides of the lower end of the movable base 1. A cleaning screw 22 is provided in the cleaning groove 19, and a cleaning guide rod 23 is provided in the cleaning guide groove 20. The cleaning brush 21 is slidably disposed below the cooling chamber 5. Cleaning sliders 24 are symmetrically fixed at both ends of the cleaning brush 21.

A cleaning motor 25 is provided in the movable base 1 to drive the cleaning screw 22.

[0027] like Figure 1 and Figure 2 As shown, the negative pressure dust collection assembly 8 includes a negative pressure chamber 26, a negative pressure fan 27, a dust collection box 28, and a dust collection port 29. The negative pressure chamber 26 is symmetrically arranged on both sides of the cooling chamber 5. The negative pressure fan 27 is located in the upper part of the negative pressure chamber 26. The dust collection box 28 is slidably arranged in the lower part of the negative pressure chamber 26 and located below the negative pressure fan 27. The dust collection port 29 is located at the lower end of the side wall of the negative pressure chamber 26 and is connected to the dust collection box 28. The dust collection port 29 is located below the protective filter 6 on the bottom wall of the cooling chamber 5.

[0028] The mobile base 1 is provided with four casters 30 at its bottom. The four casters 30 are located at the four corners of the bottom of the mobile base 1. The mobile base 1 is provided with a controller, which is electrically connected to the semiconductor cooling chip 9, the cooling fan 11, the clamping motor 18, the cleaning motor 25, and the negative pressure fan 27. The mobile base 1 is provided with a power connection cable on its outer side.

[0029] In practical use, push the mobile base 1 to the target position and lock the brake of the universal wheel 30. Place the computer host in the center of the top wall of the mobile base 1, ensuring that the air inlet at the bottom of the host is aligned with the top protective filter 6. At this time, connect the power supply through the power connection cable and start the clamping motor 18. The clamping motor 18 drives the clamping double threaded rod 14 to rotate. The rotating clamping double threaded rod 14 drives the clamping slider 17 to move in the clamping groove 12. The clamping slider 17 drives the clamping plate 16 to move horizontally. The two clamping plates 16 move synchronously towards the center of the host chassis until the clamping plates 16 clamp the host chassis tightly, preventing the host chassis from shifting and solving the problem of unstable fixation of traditional bases.

[0030] At this time, the thermoelectric cooler 9 and the cooling fan 11 are working. The air outlet of the cooling fan 11 at the cold end of the thermoelectric cooler 9 is aimed at the protective filter 6 on the top wall of the mobile base 1, which quickly transfers the cold energy at the cold end to the host and cools the inside of the host. The air outlet of the cooling fan 11 at the hot end of the thermoelectric cooler 9 is aimed at the protective filter 6 on the bottom wall of the mobile base 1, which quickly exhausts the heat generated at the hot end to the outside of the device and avoids heat accumulation.

[0031] After a period of use, the dust attached to the protective filter 6 on the bottom wall of the cooling chamber 5 will clog the mesh and affect airflow. At this time, the cleaning motor 25 is started, which drives the cleaning screw 22 to rotate. The rotating cleaning screw 22 drives the cleaning slider 24 to move linearly along the cleaning groove 19. The cleaning slider 24 drives the cleaning brush 21 to move horizontally. The cleaning brush 21 moves back and forth along the bottom protective filter 6. At the same time, the negative pressure fans 27 on both sides are started. The rotating negative pressure fans 27 generate negative pressure in the negative pressure chamber 26. At this time, the dust brushed by the cleaning brush 21 is sucked into the dust collection box 28 by the dust suction port 29. After the dust cleaning is completed, the dust collection box 28 is pulled out, the dust in the dust collection box 28 is emptied, and then it is put back in its original position.
