Description
Technical field
The utility model relates to compressor field, especially a kind of electric piston formula compressor for car air-conditioner.
Background technique
New-energy electric vehicle has the advantages that no pollution, low noise, energy-efficient.The matched pneumatics of New-energy electric vehicle
Machine is vehicle braking, car door opening and closing, suspension pedal is gone up and down and the pneumatic device of body sway provides required compressed air.To sky
Press requires that light-weight, the service life is long, compact-sized, high reliablity, with small vibration, low noise, energy-efficient, is wanted with meeting vehicle
It asks.But traditional piston compressor driven by the engine cannot be directly used to electric car, the main reason is that driving is dynamic
Power source is changed, and power source is simply changed to motor, also due to calorific value is big when motor works, is easy to cause electricity
The decline of machine power, the lost of life, failure rate increase.For this reason, it may be necessary to be further improved.
Summary of the invention
The purpose of this utility model is generated heat greatly aiming at electric piston formula compressor in the prior art, heat dissipation effect difference
Deficiency provides a kind of electric piston formula compressor, the compressor by the way that the inlet channel of compressor is extended on electric machine casing,
Motor being cooled down with will pass through coolant media in reflux course, to effectively enhance motor radiating effect, eliminating or subtracting
Few power of motor decline, the lost of life, the increased hidden danger of failure rate.
To realize foregoing purpose, the utility model adopts the following technical solution.
A kind of electric piston formula compressor, including motor and piston compressor, motor include electric machine casing and motor
Axis, piston compressor include swash plate, balance, compression cylinder and piston and air inlet and exhaust outlet, the tail of the electric machine casing
An annular groove is formed on the end face of end, the notch of annular groove is blocked by motor rear cover and the first gasket；The air inlet
Mouth is connected by annular groove side wall and annular groove, and the slot bottom of annular groove is formed with a plurality of air-cooled channel, air-cooled channel edge
Electric machine casing length direction extends, which constitutes a part of the inlet channel of piston compressor.
Using the utility model of aforementioned schemes, by the way that a plurality of air-cooled channel is arranged on electric machine casing, and this is air-cooled
Channel constitutes a part of the inlet channel of piston compressor, and during the work time, the coolant media of reflux passes through heat to compressor
Conduction cools down motor, so that the temperature in the motor course of work be effectively reduced, prevents from overheating, to avoid out efficiency from dropping
Low, failure rate increases and lost of life phenomenon.
Preferably, the compression cylinder front end is equipped with high pressure end cap；The electric machine casing is longitudinally run through in the air-cooled channel
With high pressure end cap, air-cooled Channel front end is sealed by high pressure end cap and the second gasket.It is formed using reflux coolant media to compression
The cooling of machine cylinder part can extend the service life of piston compressor part.
Preferably, balance front end flexural pivot has mandril, and mandril is slidably fitted in compression cylinder from its rod segment
In hole, compressed spring is set in the rod segment of mandril, compressed spring is located between the head and compression cylinder of mandril.Cylinder is being located
During suction stroke, the elastic force compensating using spring can be improved or eliminate swash plate side clearance increase corresponding with balance to become
Gesture, thus reduce cylinder by air-breathing be converted to compression conversion process impact and noise.
The utility model has the beneficial effects that structure is simple, compact layout, to generate heat small, runs low noise, failure rate is low,
Long service life.
