Description

Technical Field

[0001] The utility model relates to the technical field of radiator fans, in particular to a radiator fan with a protective cover. Background Art

[0002] Radiator fans are relatively common components and are often used in computer hosts. The function of a computer radiator fan is to effectively reduce the temperature of internal computer components (especially high heat sources such as processors and graphics cards) by accelerating air circulation, thereby preventing performance degradation, failures, and even damage caused by overheating, ensuring stable operation of the computer and extending its service life. In short, the radiator fan is the core component of the computer's cooling system, ensuring computer performance and lifespan through efficient heat dissipation.

[0003] The fan of a traditional radiator is installed in a shell, and the outside of the shell at the fan blade position only has a cross-shaped bracket as a protective baffle. The four corners of the shell contain bolt mounting holes, which are assembled with the host chassis after the bolts pass through the mounting holes. However, many chassis have many wires inside, and the wires often get twisted and contact the fan blades after passing through the cross bracket, thus hitting the wires when the fan blades rotate. This will not only cause the fan blade speed to decrease, but also easily cause damage to the wire sheath, thereby affecting the transmission of data information in the wires. Utility Model Content

[0004] The main purpose of the utility model is to provide a radiator fan with a protective cover, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

A mesh plate 4 of matching size is embedded inside the heightened frame 3 located above the inner edge plate 31, and a slot 41 is bored in the mesh plate 4 at the position of the plug-in block 32. The four corners of the top of the fan 1 are all bored with mounting holes 11, and the interior of the mounting holes 11 are all bored with through holes 12. The four corners of the outer edge plate 2 are all bored with An outer through-cavity 21 is formed, and an inner cylinder 22 is fixedly installed inside the outer through-cavity 21. An inner through-cavity 23 is excavated at the inner bottom of the inner cylinder 22. Hexagonal bolts 5 are inserted into the inner cylinder 22. An outer frame 33 is fixed at both ends of the outer wall of the heightened frame 3 above the inner edge plate 31. Block grooves 35 are excavated on the side walls of the heightened frame 3 at the position of the outer frame 33. An insert block 2 37 is inserted and slidably at one end of the outer frame 33 close to the block groove 35. An insert rod 38 is fixed to one end of the insert block 2 37 located inside the heightened frame 3. A rod hole 36 is excavated on the side of the outer frame 33 away from the heightened frame 3.

[0024] Specifically, one end of the inner cylinder 22 passes through the outer through-hole 21 and is inserted into the interior of the mounting hole 11 , and the hexagonal bolt 5 is respectively connected to the inner cylinder 22 and the through-hole 12 .

[0025] Specifically, one end of the second inserting block 37 away from the inserting rod 38 is connected to the block groove 35 , and one end of the second inserting block 37 passing through the block groove 35 is inserted into the side of the mesh plate 4 away from the inner edge plate 31 .

[0026] Specifically, the mesh plates 4 are in contact with the side walls of the inner edge plates 31 , and the inserting blocks 32 are inserted into the slots 41 , forming a basic limiting effect.

[0027] Specifically, the insertion rods 38 are respectively passed through the rod holes 36 and then slidably connected. The insertion rods 38 can pull the second insertion block 37 to move, thereby facilitating the operation during disassembly.

[0028] Specifically, a spring 34 is sleeved on the outer wall of the insertion rod 38 at one end inside the outer frame 33, and the two ends of the spring 34 are respectively fixed to the side wall of the outer frame 33 close to the rod hole 36 and the side wall close to the insertion block 2 37, so that the insertion block 2 37 can be stably inserted into the upper surface of the mesh plate 4, achieving the effect of stabilizing its position.

[0029] Working principle:

[0030] The outer edge plate 2 is inserted into the interior of the mounting hole 11 through the inner cylinder 22 located in the outer through-hole 21, and the hexagonal bolt 5 passes through the inner through-hole 23 of the inner cylinder 22 and then passes through the mounting hole 11 and the through-hole 12, so that the fan 1 and the outer edge plate 2 can be assembled together, and the mesh plate 4 can be located inside the heightening frame 3. The mesh plate 4 protects the blades in the fan 1 during operation, preventing the passage of the wire from affecting the rotation of the blades and damaging the wire sheath, thereby having a good protective effect.

[0031] When the screen 4 is clogged by dust or lint and affects the heat dissipation performance, this application includes two disassembly operations for cleaning the screen 4, as follows:

[0032] The first method: After the hexagonal bolt 5 is disassembled, it is pulled out from the through hole 12 and the inner tube 22. At this time, the outer plate 2 and the heightening frame 3 can be removed, and the screen plate 4 can be cleaned;

[0033] The second type: the mesh plate 4 is located on the inner edge plate 31 of the heightening frame 3, and the basic limit is obtained by inserting the plug block 1 32 into the slot 41, and the pushing force of the spring 34 on the plug block 2 37 will push it out from the position of the block groove 35. The plug block 2 37 after being ejected is inserted into the surface of the mesh plate 4, forming a blocking state, so that the mesh plate 4 can be stably located on the inner edge plate 31. When the mesh plate 4 needs to be removed, the insertion rod 38 is pulled horizontally toward the end away from the plug block 2 37, so that the plug block 2 37 is retracted from the surface of the mesh plate 4 to the block groove 35 of the heightening frame 3. The mesh plate 4 can then be easily removed from the inside of the heightening frame 3 because there is no obstruction.
