[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1-5 As shown, a digital audio processor with noise reduction function includes a body 1 and vents 3 that are movably mounted on both sides of the body 1.

[0025] Multiple heat pipes are provided corresponding to electronic components and used to receive heat, including a first heat pipe 34 and a second heat pipe 36 sequentially arranged along the air inlet direction of the vent 3;

[0026] The heat pipe has a constriction opening at the first end facing the vent 3 and a narrow opening at the second end opposite it. The first heat pipe 34 and the second heat pipe 36 are connected together, and a suction channel is formed between the constriction opening and the narrow opening.

[0027] Specifically, the main body 1 is also provided with a heat dissipation vent 11, and a third converging port 37 pointing towards the heat dissipation vent 11 is sleeved at the second end of the second heat pipe 36. An air outlet 38 is provided on the third converging port 37. The first heat pipe 34, the second heat pipe 36 and the third converging port 37 are all fixedly disposed inside the main body 1. The converging ports include a first converging port 33 fixedly disposed on the first heat pipe 34 and a second converging port 36 fixedly disposed on the second heat pipe 36, and the second heat pipe 36 is sleeved inside the first heat pipe 34.

[0028] Further, the electronic components in the body 1 are heated during operation, and the heat is transferred to the heat pipes, when the air current passes through the air vent 3, the air current is first collected by the first collecting port 33, and then enters the first heat pipe 34, when the air current passes through the narrow port of the first heat pipe 34, the air current is accelerated due to the Venturi effect, so that low pressure is generated at the narrow port, and the suction channel is formed between the narrow port of the first heat pipe 34 and the second collecting port 35, so that the suction effect is generated around the second collecting port 35, and the accelerated air current flows out through the second heat pipe 36, and the suction channel is formed again between the third collecting port 37 and the narrow port of the second heat pipe 36, and the speed of the incoming air current is accelerated due to the reduction of the inner diameter between the collecting port and the narrow port, so that the heat exchange efficiency of the first heat pipe 34 and the second heat pipe 36 is enhanced, and the hot air current is driven upward when the electronic components are heated, and flows out from the heat dissipation port 11, and the air current is introduced through the air outlet 38 to supplement, so that the circulation is formed.

[0029] In the above-mentioned technology, the suction channel for heat exchange with the electronic components is formed between the collecting port and the narrow port, the speed of the incoming air current is accelerated due to the reduction of the inner diameter between the collecting port and the narrow port, the heat exchange efficiency of the first heat pipe 34 and the second heat pipe 36 is enhanced, and the hot air current is driven upward when the electronic components are heated, and flows out from the heat dissipation port 11, and the air current is introduced through the air outlet 38 to supplement, so that the circulation is formed.

[0030] As a further provided embodiment of the utility model, the air vent 3 is provided with a drainage port 32, and the air vent 3 is provided with a guide plate 31 in a spiral array.

[0031] Specifically, the drainage port 32 is in a tapered structure with the inner diameter decreasing along the air inlet direction, so that the air current is accelerated due to the reduction of the sectional area, and the air inlet is in a spiral direction through the arrangement of the guide plate 31, so that the vortex is formed, and the air current speed is further accelerated.

[0032] As a further provided embodiment of the utility model, the air vent 3 is provided with a drainage port 32, and the air vent 3 is provided with a guide plate 31 in a spiral array.

[0033] Specifically, the body 1 is provided with a fixed shell 2 on both sides for assembling the fan 21, and the fixed shell 2 is provided with a clamping piece 22, the body 1 is provided with a clamping groove matched with the clamping piece 22, the fan 21 is assembled in the fixed shell 2, and the fixed shell 2 is used to drive the fan 21 to deflect towards the air vent 3, when the fixed shell 2 is tightly attached to the side surface of the body 1, the clamping piece 22 is clamped in the clamping groove, and at this time, the fan 21 faces the air inlet of the air vent 3, when the fan 21 needs to be cleaned, the clamping piece 22 is only needed to be disengaged from the clamping groove, and then the fixed shell 2 is deflected to be separated from the body 1, so that the fan 21 can be removed.

[0034] As a further provided embodiment of the utility model, the fixed shell 2 is provided with a pressing plate 23 for extruding the clamping piece 22.

[0035] Specifically, a spring is arranged between the pressing plate 23 and the fixed shell 2. The clamping piece 22 is slidably arranged on the fixed shell 2 through the sliding block 25 fixedly arranged thereon, and the clamping piece 22 is provided with the elastic piece 26 for extending the clamping piece 22 to the outside of the fixed shell 2, and the pressing plate 23 is provided with the transmission piece 24 in sliding cooperation with the sliding block 25. When the fixed shell 2 is tightly attached to the side of the body 1, the clamping piece 22 is clamped into the clamping groove under the elastic support of the elastic piece 26, and the pressing plate 23 and the fixed shell 2 are kept a certain distance apart by the spring. When the fixed shell 2 needs to be deflected, the pressing plate 23 is pressed down, the transmission piece 24 is driven by the pressing plate 23 to push the sliding block 25, the sliding block 25 is retracted into the fixed shell 2 through the sliding cooperation of the transmission piece 24 and the sliding block 25, the elastic piece 26 is retracted and drives the clamping piece 22 to be disengaged from the clamping groove, and the fixed shell 2 is movable at this time.

[0036] Working principle: When the fixed shell 2 is tightly attached to the side of the body 1, the clamping piece 22 is clamped into the clamping groove, at this time the fan 21 is opposite to the air inlet 3, the airflow is accelerated due to the reduction of the cross-sectional area when passing through the flow guide 32, and the air inlet is arranged in the spiral direction through the flow guide plate 31, so that the air inlet forms a vortex and further accelerates the airflow. When the airflow passes through the air inlet 3, the airflow is first concentrated by the first converging port 33, then enters the first heat pipe 34, and the airflow is accelerated due to the Venturi effect when passing through the narrow port of the first heat pipe 34, so that low pressure is generated at the narrow port. The narrow port of the first heat pipe 34 and the second converging port 35 form a suction channel, which produces a suction effect around the second converging port 35. The accelerated airflow flows out through the second heat pipe 36, at this time the third converging port 37 and the narrow port of the second heat pipe 36 form a suction channel again, the speed of the air inlet is accelerated due to the reduction of the inner diameter between the converging port and the narrow port, and the heat exchange efficiency of the first heat pipe 34 and the second heat pipe 36 is enhanced. When the electronic components are heated, the hot airflow rises and flows out from the heat dissipation port 11, and the airflow introduced through the air outlet 38 is replenished to form a circulation.

[0037] The above only describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present application.
