Title:
TENSIONER DRIVE UNIT HAVING GOOD HEAT DISSIPATION EFFECT, AND ELECTRONIC TENSIONER APPLYING SAME
Document Type and Number:
WIPO Patent Application WO/2022/213791
Kind Code:
A1
Abstract:
The present invention relates to the technical field of tensioners, and disclosed are a tensioner drive unit having a good heat dissipation effect and an electronic tensioner applying same. The tensioner drive unit having a good heat dissipation effect provided in the present invention comprises a motor unit, a driving plate provided on the axial side part of the motor unit, and a heat conduction support piece; the motor unit comprises a motor stator; the heat conduction support piece comprises a heat conduction part; the motor stator and the driving plate are respectively fixed on the heat conduction support piece; and a wind source piece is provided on the periphery of the motor unit, and the wind source piece is used to dissipate heat from the motor unit and the driving plate. In the tensioner drive unit having a good heat dissipation effect, the motor stator and the driving plate which generate a large amount of heat when working are directly fixed on the heat conduction support piece, heat generated by the two is dissipated by means of the heat conduction part having a larger heat conduction area on the heat conduction support piece, and local heat accumulation is prevented, active heat dissipation is performed on the heat conduction part and the motor unit by means of the wind source piece, and heat dissipation efficiency is higher.
