Outer wall.
By multistage axial direction water channel, multistage circumference water channel, alternately connection is formed the water channel successively, adjacent two sections of axial water channels,
One section of circumferential water channel connects into a U-shaped unit.
The water inlet and delivery port are connected with same axial water channel.
The water pipe head of the water inlet, delivery port is through on bolt hole of the bolt loaded on housing.
The axial water channel inwall is dentation, and the angle of tooth form designs according to water channel cross-sectional sizes, axial water channel sectional area
It is computed meeting that motor cooling requires with perimeter of section ratio.
It is axially disposed in the housing to have multiple interior muscle, axial water channel is formed in adjacent two between muscle, outside the housing
By stretching one-shot forming, each interior muscle inner end alternating machine add-on type is arc surfaced circumferentially water channel for shape, interior muscle, axial water channel,
Housing both ends connect water channel, block is using casting molten aluminium alloy side by polylith Welded from outside enclosure
Method is formed.
The interior muscle outer end is provided with the mounting hole for being used for installing electric motor end cap.
The utility model solves enclosure interior water channel coolant leakage problems, simplifies Shell Manufacture, reduces manufacture
Cost, realize production mass, there is provided a kind of good airproof performance, intensity are high, the water-cooled housing of rapid heat dissipation.Water channel side inwall is tooth
Face, water channel is connected with multiple aluminium block welded closures, solve in the prior art that radiating is slow, water channel difficulty of processing is big, cost is high
Technical problem.
Compared with prior art, the utility model has subordinate's technique effect：
1. housing water channel cross-sectional dimension of the present utility model meets flow resistance requirement, using tooth form internal face, fluid is played
Guide effect, the contact area of increase water channel and motor internal thermal source, improving radiating effect.
Using being that U-shaped water route is designed, 2. cyclic water channel in housing, water channel length and section calculate and met the utility model
Flow resistance requirement, water route is unimpeded, water-tight, and manufacturing process is simple, can mass.
3. the stretch forming process of housing of the present utility model is applied to the different length housing of processing homologous series motor,
The lead time is shortened, reduces manufacturing cost.
4. the location and installation pore size distribution of housing of the present utility model and electric motor end cap in stretching housing at muscle, ensure that
Casing rigidity.
