High-efficiency heat dissipation motor frame suitable for various explosion-proof types

Abstract

The invention discloses an efficient heat dissipation motor base suitable for various explosion-proof types. The efficient heat dissipation motor base comprises a base cylinder, and outer base heat dissipation ribs axially arranged on the outer surface of the base cylinder; inner base heat dissipation ribs I in the axial direction and inner base heat dissipation ribs II in the circumferential direction are arranged at the positions, corresponding to the outer base heat dissipation ribs, on the inner sides of the end parts of the base cylinder. The outer base heat dissipation ribs are relatively compact in appearance; the axial or ring-shaped inner base heat dissipation rib structures are added at the end parts of the base, so that the heat dissipation area is greatly increased, the heat inside the motor can be emitted to the periphery space from the base in time, the cooling effect of the motor is ensured, and moreover, on the basis of increasing the heat dissipation area, the air resistance is relatively small, the heat dissipation factor and the air resistance magnitude are balanced, and then favorable conditions are formed for motor cooling; besides, the motor is larger in capacity, can be suitable for various explosion-proof places (Ex d I Mb, Ex d II A T4 Gb, Ex d II B T4 Gb, and Ex d II C T4 Gb), is relatively high in universalization degree, and is more suitable for batch production of enterprises.

Description

technical field [0001] The invention relates to the field of motors, in particular to a high-efficiency heat dissipation motor base suitable for various explosion-proof types. Background technique [0002] The traditional motor cooling rib structure frame is equipped with four sets of cooling ribs between the four axial ventilation channels. Although the heat dissipation area of ​​the outer surface of the frame is increased, the ventilation channel as the main cooling channel of the frame is not fully considered. Moreover, there is a problem that the air passage area of ​​the ventilation duct is smaller than the inlet and outlet areas, so that it does not achieve the best cooling effect. In addition, the foot of the machine base is often cracked during the production process. Connected to the frame, the cost of the motor increases and there is also an unreliable factor. In addition, the cast iron frame with the traditional heat dissipation rib structure needs to use differe...

Problems solved by technology

Therefore, when the number of heat sinks is too large, the heat inside the motor cannot be dissipated to the surrounding space in time, which will also affect the cooling effect of the motor.
