Description
Technical field
The invention belongs to technical field of motors, more particularly, to a kind of water-cooled machine that can be air-cooled.
Background technique
Currently, since motor is when carrying out energy conversion certain heat can be generated, therefore in the operation of motor, need
The heat that motor generates to be distributed in time, otherwise motor temperature is excessively high will lead to the decline of motor performance index, even
Damage motor internal circuit.
The motor type of cooling currently on the market is mainly air-cooled and water cooling, wherein can air-cooled water-cooled machine be by
Cavity is set on casing, then by the water being passed through in cavity, is exchanged heat by the heat inside water body motor, still
Existing water-cooled machine that can be air-cooled passes in and out water-bound in use, by being arranged on the casing of motor, then again
An external water tank is connected by hose, is then sent the water pump in water tank in cavity back to by the pump housing, but because water
The volume of case is larger, and the space occupied is bigger, therefore when motor installation, it has not been convenient to motor is installed, and
Because motor is when installation, the disengaging water-bound on motor carries out it to protrude from casing outer wall, thus to motor into
When row installation, disengaging water-bound can be installed in equipment obstruction to motor；And motor is passing through water cooling at present
When, in use because internal heat mode that is larger, and cooling down simply by water cooling, will appear heat
Amount is difficult to quickly volatilize, therefore good cooling is difficult to realize during water cooling.
Summary of the invention
The present invention for overcome the deficiencies in the prior art, provides a kind of water-cooled machine that can be air-cooled of good cooling effect.
To achieve the goals above, the invention adopts the following technical scheme: a kind of water-cooled machine that can be air-cooled, including
Casing with waterway, the waterway is interior to be filled with refrigerant；
Multiple interconnecting pieces on the casing；
Stator in the casing；
Rotor in the casing；
The circulator being detachably connected with interconnecting piece described in one of them, the circulator is for extracting out in the waterway
Refrigerant is with cooling refrigeration agent；

Preferably, the circulator includes the bracket being detachably connected with the interconnecting piece, is formed on the bracket
First pipe, the cooling box on the bracket, the second pipe being detachably connected with the first pipe and for will
Refrigerant in the waterway is evacuated to the pump housing in the cooling box, and the pump housing is set on the bracket；By by second
Pipeline is arranged on bracket, and one side is a simplified the structure of bracket, reduces materials, can incite somebody to action when manufacturing bracket
Second pipe is produced, and without additional setting pipeline, has been saved materials, has also been avoided to pacify first pipe certainly
Dress；On the other hand because bracket is connected with the casing, in order to ensure the intensity of bracket, bracket is made of metal material, because
This first pipe is arranged on bracket, and refrigerant can immediately pass through bracket when flowing and radiate, and bracket surrounding
It is empty, good heat dissipation effect.
Preferably, the cooling box include box body, spiral be set to the intracorporal second pipe of the box, be filled in the box body
Interior heat exchange liquid and part contacts copper heat-conducting piece of the another part outside the box body, second pipe with the heat exchange liquid phase
Road is detachably connected with the first pipe；It is connected by setting second pipe with first pipe, it is achievable to pass through first
Pipeline outflow refrigerant enter in second pipe, should during the cold liquid of box body interior suction can to the heat in refrigerant into
Row replacement, so that refrigerant can cool down, so that refrigerant can realize quick cooling, so that refrigerant is entering in casing,
Realization cools down to the temperature in casing, and the effect of cooling is good, and copper heat-conducting piece is arranged can be by the heat in the liquid that exchanges heat
