But the above-mentioned noun of locality is not intended to limit the invention.
In order to solve the problems, such as that the working performance of compressor in the prior art is poor, this application provides a kind of compressor and
With its heat transmission equipment.
As shown in Figure 1 to Figure 3, compressor includes housing 10, pump assembly 20 and motor 30.Wherein, pump assembly 20 is set
It puts in housing 10.Motor 30 is arranged in housing 10 and positioned at the top of pump assembly 20, the breathing area of motor 30 and
The sum of interval area between motor 30 and housing 10 is top area of passage summation S1, top area of passage summation S1 and compression
The ratio between capacity of machine is predetermined value A, and meets 0.01≤A≤0.085.
Using the technical solution of the present embodiment, during compressor operating, top area of passage summation S1 and compressor
The rational design of the ratio of capacity can reduce the gas of the upper and lower both sides of motor, and then reduce since gas is led
The compressor air-discharging loss of cause promotes the working performance of compressor.Meanwhile the reduction of compressor housing interior air-flow pulsation also can
It makes moderate progress to the running noises of compressor, improves user experience.
In the present embodiment, top area of passage summation S1, interval area S2 and lower part area of passage summation S3 units are
mm2, the capacity unit of compressor is mm3。
In the present embodiment, the above-mentioned parameter design of compressor can save substantial amounts of test period, can test resource, be
Subsequent development provides shortcut, reduces the development cost of compressor.
As shown in figure 4, predetermined value A is when in the range of 0.01~0.085, the discharge loss of compressor be it is minimum, because
And the working performance of compressor is optimal, and work efficiency highest.Meanwhile the noise of the compressor in the numberical range is changed
It is kind.
As depicted in figs. 1 and 2, motor 30 includes rotor 31 and the stator 32 that is set in outside rotor 31, logical on rotor 31
The sum of interval area between stomata, stator 32 and rotor 31 is breathing area.Specifically, the high temperature positioned at 30 lower section of motor is high
Body of calming the anger can pass through between the gap between the venthole on rotor 31, stator 32 and rotor 31 and motor 30 and housing 10
Gap flow to the top of motor 30.The above-mentioned setting of the ratio between the capacity of top area of passage summation S1 and compressor can
High temperature and high pressure gas is prevented to be again introduced into pump assembly 20 so that the most of high temperature and high pressure gas discharged from pump assembly 20
The top of motor 30 is entered to by above-mentioned gap and venthole, and is discharged from housing, so that 30 upper and lower both sides of motor
Interior air-flow, which is pulsed, to be effectively reduced so that discharge loss is minimized caused by gas, promotes compressor
Work efficiency.In addition, the reduction of gas can also make moderate progress to the noise of compressor, user experience is improved.
Optionally, gap of the gap between motor 30 and housing 10 between 32 trimming of stator and housing 10.

Divide gas that can pass through connectivity structure 211 into the lower section of housing 10, the area and upper flange 21 and housing of connectivity structure 211
The sum of interval area S2 between 10 is lower part area of passage summation S3, and lower part area of passage summation S3 and top area of passage are total
It is predetermined value B with the ratio between S1, and meets 2≤B≤6.It is disturbed in this way, above-mentioned setting can reduce gas in housing 10 so that from
The high temperature and high pressure gas that pump assembly 20 is discharged can be preferably distributed, and the high temperature for being lowered into the lower space of upper flange 21 is high
It calms the anger the scale of construction, shortens the exhaust pathway of gas, reduce the discharge loss of compressor.
Specifically, when compressor is run under high frequency operating mode, since compressor spits the increase of oil cut rate, lubricated in housing 10
Oily quantity is reduced so that fluid potential drop is low, and the cavity of resorption volume of motor 30 becomes larger at this time.Top area of passage summation S1 and compressor
The ratio between capacity and the ratio between lower part area of passage summation S3 and top area of passage summation S1 reasonable setting, can reduce
Into the high temperature and high pressure gas amount of 30 times intracavitary of motor, the gas disturbance in housing 10 is reduced, so that from pump assembly 20
The high temperature and high pressure gas of discharge are better distributed, and reduce inlet of the high temperature and high pressure gas to 21 lower space of upper flange,
So as to reduce the loss of this portion discharge, the work efficiency and working performance of compressor are improved.
As shown in figure 5, predetermined value B is when in the range of 2~6, the discharge loss of compressor is minimum, thus compressor
Working performance it is optimal, and work efficiency highest.Meanwhile the noise of the compressor in the numberical range is improved.

As shown in figure 3, having notch 212 at the outer rim of upper flange 21, the outer rim and the inner wall of housing 10 of upper flange 21 connect
It touches, and the interval area S2 between upper flange 21 and housing 10 is formed at notch 212.Above-mentioned setting causes upper flange 21 in shell
Assembling in body 10 is more prone to, but also the processing of upper flange 21 is more prone to.
Specifically, the area of notch 212 is interval area S2, and the summation of interval area S2 and 211 area of connectivity structure
For lower part area of passage summation S3, and the ratio between lower part area of passage summation S3 and top area of passage summation S1 are predetermined value B, and
Meet 1≤B≤4, and then the high temperature and high pressure gas for reducing the discharge out of pump assembly 20 enter to the gas of 20 lower section of pump assembly
The scale of construction prevents that flow perturbation occurs in housing 10, promotes the working performance of compressor.
As shown in Figure 1, upper flange 21 has along its axially extending axle journal, upper flange 21 also has flange exhaust outlet 213,
Compressor further includes noise-reducing structure 40.Wherein, noise-reducing structure 40 is set on axle journal, noise-reducing structure 40 and flange exhaust outlet 213
And the inner cavity of housing 10 connects, and the gas discharged from flange exhaust outlet 213 is directed into the interior intracavitary of housing 10.In this way,
Noise-reducing structure 40 can reduce the noise during compressor operating, improve user experience.
