Problems solved by technology

[0002] At present, most cooling fans are developed with brushless DC motors as drivers. Because brushless DC motors cannot move by themselves, they need to be controlled by chips to move, which leads to the price comparison of fans developed with brushless DC motors. Expensive, and has a large volume, and the application scene is relatively simple, and the air volume is limited

Embodiment Construction

[0016] Below according to the attached Figure 1 ~ Figure 3 , give a preferred embodiment of the present invention, and give a detailed description, so that the functions and characteristics of the present invention can be better understood.

[0017] see figure 1 with figure 2 , a small modular heat dissipation device implemented in the present invention includes a housing 1, a DC brushed motor 2 and an impeller 3, and the DC brushed motor 2 is connected to the impeller 3 by transmission. The housing 1 forms a chamber (not shown), the impeller 3 is arranged in the chamber, the housing 1 forms an air outlet 11 at a position corresponding to the chamber, and the air outlet 11 communicates with the chamber and along the The axial direction of the impeller 3 is provided. In this embodiment, the chamber is cylindrical, the axial direction of the chamber is the same as the axial direction of the impeller 3 in the chamber, and the casing 1 extends along the tangential direction o...

Abstract

The invention provides a small modularization heat dissipation device comprising a shell body, a direct current brush motor and one or more impellers. The direct current brush motor and the impellers are in driving connection. Each impeller comprises a plurality of vanes which are in long strip shapes. The shell body forms one or more cavities. Each vane is arranged in the corresponding cavity. One or more air outlets are formed in the position, corresponding to each cavity, of the shell body, wherein the air outlets communicate with the cavity and are formed in the axial direction of the corresponding vane in the cavity. The small modularization heat dissipation device has the advantages of being small in size, simple in driving, large in air outlet volume, simple in assembly, easy to operate, high in cost advantage and small in working power.

Description

technical field [0001] The invention relates to the field of heat dissipation devices, in particular to a small modular heat dissipation device. Background technique [0002] At present, most cooling fans are developed with brushless DC motors as drivers. Because brushless DC motors cannot move by themselves, they need to be controlled by chips to move, which leads to the price comparison of fans developed with brushless DC motors. It is expensive and has a large volume, and the application scenarios are relatively simple, and the air output is limited. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a small modular cooling device, which has the advantages of small size, simple driving, large air output, simple assembly and easy operation, high cost advantage and low working power. [0004] In order to achieve the above object, the present invention provides a fully automatic dimming actuator f...
