Background technique

Computer radiator is a device or instrument that transfers the heat generated by machinery or other equipment during work in time to avoid affecting its normal operation. Common radiators can be divided into air cooling, heat pipe radiator, liquid cooling, semiconductor refrigeration, compressor refrigeration and other types according to the heat dissipation method.

The existing technology, such as application number: CN216388010U, discloses a low-noise computer radiator, which includes a fin assembly, a cooling fan is fixedly connected to the top of the fin assembly, and the bottom end of the fin assembly is sleeved There is a fairing, the top surface of the fairing is in contact with the bottom surface of the cooling fan, and the annular outer wall of the fairing has an equiangular opening. In the utility model, through the arrangement of the fairing and the sponge mesh, the cooling fan operates, and the airflow passes through the sponge mesh and enters the fin assembly through the vent. The airflow takes away heat when passing through the fin assembly, and the hot airflow passes through the cooling fan. It is discharged to the outside world, and the sponge mesh is used to filter the passing airflow and filter out the dust in the airflow, thereby reducing or preventing the fan blades from being contaminated with dust when the airflow passes through the cooling fan, keeping the fan blades in a relatively clean state. This allows the radiator to maintain low noise and is convenient to use after a period of use.

Another prior art, CN110806790A, a computer radiator

CN115933845A, a computer radiator

CN114253377A, a special computer radiator

However, there are still certain problems when using the above typical and other existing technologies:

The noise of the radiator is generally small when in use, but after a period of use, dust will accumulate on the surface of the fan blades, causing the weight of each blade to deviate, causing the center of gravity of the fan blades to deviate when rotating, and the noise when the fan blades are running. will gradually increase and produce louder noise. In the above comparison document, dust removal is used to reduce the noise of the fan blade rotation. In the comparison document, the sponge mesh uses a dust filtering method to prevent the fan blades from being contaminated with dust, but the surface of the sponge mesh will change with time. As dust increases, clogging problems will occur. When the sponge mesh accumulates a lot of dust, it cannot effectively filter the dust, and the fan blades are still easily contaminated with dust. Therefore, it is necessary to design a low-noise computer radiator that can automatically clean the dust.
