Problems solved by technology

[0005] However, when the fan wheel 92 of the horizontal convection fan 9 is installed in the horizontal airflow channel 913, since each of the blades 922 is formed on the outer peripheral surface of the fan wheel 92, and the top edge of each of the blades 922 is aligned with the The top surface of the hub 921, therefore, when the blades 922 of the fan wheel 92 guide the airflow along the horizontal airflow channel 913 to generate convection, the airflow will be easily hindered by the hub 921, thereby generating turbulence, And reduce the overall cooling effect of this existing horizontal convection fan 9

Abstract

An advection-type fan includes a fan frame, a driving module and an impeller. The fan frame has a first cover portion, a second cover portion and a lateral wall portion arranged between the first and second cover portions, wherein the lateral wall portion has an air inlet and an air outlet. The driving module (2) is received in the fan frame and coupled with the first cover portion. The impeller has a hub and a plurality of vanes. The hub is rotatably coupled with the driving module and the vanes are coupled with the hub . The hub has an air-guiding plane facing the second cover portion. Each of the vanes has a top edge facing the second cover portion (12). The top edge of each of the vanes is higher than the air-guiding plane of the hub in an axial direction of the hub.

Description

technical field [0001] The invention relates to a horizontal convection fan, in particular to a horizontal convection fan capable of introducing and exporting airflow in a horizontal direction. Background technique [0002] Existing heat dissipation fans generally include two types: axial flow heat dissipation fans and blast heat dissipation fans. Among them, the axial flow cooling fan has an axial air inlet and an axial air outlet opposite to each other in the axial direction, so as to introduce air flow through the axial air inlet, and then export air flow through the axial air outlet, thereby providing heat dissipation function Also, the blower cooling fan has an axial air inlet in the axial direction, and a radial air outlet in the radial direction, so that the airflow can be introduced through the axial air inlet, and then pass through the radial air outlet side. The guide guides the airflow, but also has the function of cooling. [0003] However, as far as the axial ...
