Description

Technical Field

[0001] The utility model relates to the field of computer case heat dissipation systems, in particular to a case structure with parallel heat dissipation channels. Background Art

[0002] With the development of computers, the requirements for heat dissipation systems are becoming higher and higher. The heat dissipation of the existing space in the chassis is generally achieved by setting a plurality of axial flow fans distributed along the height of the front plate of the chassis, so as to make the fluid flow from the front plate to the rear plate. However, although the axial flow fan has a faster rotation speed, its fluid stroke is short, so it mainly serves to transport the fluid into the chassis to achieve fluid exchange. The heat exchange efficiency is low, and the overall heat dissipation of the internal space cannot be achieved. Utility Model Content

[0003] The main purpose of the utility model is to provide a chassis structure with parallel heat dissipation channels, aiming to improve the above technical problems.

[0004] To achieve the above object, the utility model proposes a chassis structure with parallel heat dissipation channels, comprising:

[0005] A box body, wherein a front plate is provided at the front end of the box body, an air inlet is provided at the front plate or a side wall of the box body, and the front plate and the front wall of the box body form a positioning interval;

[0006] A crossflow fan, the crossflow fan is arranged in the positioning interval and is provided with at least one, the crossflow fan comprises pivot seats arranged at intervals and impellers installed on the pivot seats, one of the pivot seats is provided with a rotating device for driving the impeller to rotate, the pivot seat is installed in the positioning interval,

[0007] The impeller is vertically arranged along the height direction of the box body, and the impeller can drive the fluid to flow from the air inlet toward the rear plate position of the box body.

[0008] In the actual design, the cross-flow fan can be set on the front wall of the box or installed on the front plate, which is convenient for the installation of the cross-flow fan. In the actual operation of the impeller, its height is consistent with the height of the inner space of the box. Therefore, when it rotates, the overall heat dissipation of the inner space can be achieved, and the fluid flow rate generated by the cross-flow fan is faster and its flow process is longer, which can achieve rapid exchange of the fluid.

[0009] That is, the air volume is increased and the noise is reduced (less turbulence). BRIEF DESCRIPTION OF THE DRAWINGS
