[0004] But when the outside air enters the casing 12, dust will be brought into the air passage 13, and then adsorbed on the fan 11, so after the fan 11 has been running for a long time, due to the adsorption of a large amount of dust, it will reduce its heat output. extracted potency

Abstract

The invention relates to a method for reducing dust adsorption by a casing fan and a casing device with a dust removal device. Specifically, a casing device with a dust removal device includes a casing, a fan and a dust removal device. The casing defines a gas channel. The fan is arranged in the casing and is located at the end of the gas channel, and is used for exhausting the gas from the casing. The dust removal device includes an airflow interference component and an adhesive component. The airflow disturbing component is arranged in the casing and located upstream of the fan, and is used for disturbing the airflow to the fan. The adhesion component is disposed downstream of the airflow disturbance component, and is used for adhering dust entrained by the airflow and falling when the airflow is disturbed. The present invention uses the design that the adhesive component is located upstream of the fan and the airflow interference component is located upstream of the adhesive component, so that the airflow interference component interferes with the passing airflow, so that the dust entrained by the airflow falls on the adhesive component and is adhered, thereby reducing the dust adsorption of the fan the goal of.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a casing device with a dust removal device which can reduce the dust adsorption of a fan. Background technique [0002] As the speed of the current notebook computer is getting faster and faster, more and more heat is generated. If the heat is not quickly taken away from the inside, it will seriously affect the stability of the system operation, and even cause overheating. Unexpected downtime occurs. At present, the heat dissipation method commonly used in the industry is to use the forced convection heat dissipation method formed by the heat dissipation module (heat pipe plus heat dissipation fin) and the fan to dissipate heat. [0003] refer to figure 1 , when the fan 11 rotates, the air outside the casing 12 is brought into the gas passage 13 defined by the top wall 121 and the bottom wall 122 of the casing 12 through the air inlet 123, so that the gas flows in the gas passage 13 in ...
