Embodiment Construction

[0030] Referring to Fig. 1, in this embodiment, the electronic device of the present invention is a projector module 10, especially a large-scale projector used in meetings, which includes a housing 11, a channel 12, a light source L, an optical engine E, two The first fan F1, the second fan F2 and the blower F3, wherein the casing 11 has an inner space S.

[0031] The housing 11 has an air inlet 111 and an air outlet 112. The channel 12 is a cooling flow channel provided in the inner space S, which is used to discharge the hot air generated by the projector module 10 during operation to the outside of the housing 11. The channel 12 It has a first port 121 and a second port 122, wherein the first port 121 and the second port 122 are respectively arranged at the air inlet 111 and the air outlet 112, and bypass from one side of the optical machine E.

[0032] The light source L is the main heating element in the projector module 10 , and it is arranged in the channel 12 , and th...

Abstract

The invention discloses an electronic device, which comprises the following parts: case, channel and multiple first fans, wherein the case has internal space; the channel is set in the internal space; multiple first fans are cascaded in the channel, which can maintain lower rotary speed to reduce noise effectively.

Description

technical field [0001] The present invention relates to an electronic device such as a projector module, which can reduce overall noise by using fans arranged in series. Background technique [0002] Usually, a fan is provided in the projector module to dissipate heat and achieve the purpose of cooling down. In the configuration of the existing projector module, generally only one fan is arranged, or more than one fan is arranged in parallel to increase the air volume. [0003] However, although increasing the number of fans can increase the air volume and achieve the effect of rapid cooling, the noise generated by the fans also increases relatively. How to increase the air volume without increasing the noise has become the main consideration in the design of the projector module. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide an electronic device that can increase the air volume without increasing the noise. [00...
