Description
Technical field
Control system, a kind of fastening system and one kind that the present invention relates to a kind of for adjusting or controlling compressor apparatus
Compressor apparatus with control system.The invention further relates to a kind of methods for manipulating compressor apparatus.
Background technique
In compressor or pressurizer, gas pressurized is usually become into liquid, these liquid are during difference into one
Step uses.For example, freezing and using certain refrigerants, such as CO under air-conditioning technical2, these refrigerants are pressurized in the circulating cycle.
In the case where the compressor of air conditioner especially used in a motor vehicle, pressurizeed by means of electric drive portion.Here, in order to have
Sharp land productivity with being limited existing structure space in a motor vehicle, value it is desirable that, by control circuit (especially circuit board or print
Printed circuit board) it connect or integrates with compressor housing, control circuit is loaded with the corresponding manipulation ministry of electronics industry.
Difficulty in this is for example, due to pressure oscillation, the shell face of compressor may arching or movement.Here, answering
Bending stress is not transmitted in the mechanically and electrically subcomponent of the manipulation ministry of electronics industry by this as far as possible.
Summary of the invention
In this context, task of the invention lies in: provide a kind of electronic control device for compressor apparatus can
Advantageous fastening possibility on the face of deformation.
Therefore, it is proposed to a kind of for adjusting or controlling the control system of compressor apparatus, which, which has, is used for
The shell of compressed fluid.The deformable structural detail of the shell is arranged in the first pressure area and second of compressor apparatus
Between pressure area.Control system includes: electrical power module；Coldplate, coldplate are configured for heat from the electrical power mould
Block guides, which is thermally coupled on coldplate；With the fastening system for coldplate.The fastening system has multiple
Coldplate is spaced apart by spacer element, these spacer elements with structural detail, wherein these spacer elements are arranged so that structure
The transmitting of deformation toward the coldplate of element is reduced, is especially prevented from.
The component of the electronic control system of power module especially compressor apparatus.Here, control system may include other
Electronic structure element, such as power semiconductor, switch, processor, memory and analog.In embodiments, electronic control system

On the one hand from bending stress on the other hand from thermal stress.
Preferably, coldplate is spaced apart by means of spacer element with structural detail, so that even if compressor apparatus is in structure
When conventional operation under deformed element or the maximum case that arches upward, additional reinforcing is also formed not between structural detail and coldplate
Point.This has the advantages that coldplate and other machinery are connected to element thereon not by additional bending stress.In
It is, such as the deformation of the form to arch upward of flat structural detail is not transmitted on coldplate, because of structural detail face
Deformation in the axial direction can be used as offset movement and occur between the position of spacer element, and not generate in coldplate
Extra-stress.Here, coldplate is not preferably hindered on the direction of offset movement by inelastic barrier.This respect is come
It says, control system simply and spends low land to be integrated into the shell in the shell of compressor apparatus or being integrated into compressor apparatus
On.
First pressure area is, for example, the low-pressure area of compressor, and second pressure area is the region with atmospheric pressure.Structural elements
Part for example can correspond to housing bottom, and the housing bottom is due to being present between pressure and external pressure inside compressor
Pressure oscillation and deform, moulding, distort, arch upward or be bent.For example, causing intracorporal in shell in compressor apparatus operation
Pressure change from 3MPa to 8.5MPa or from 30bar to 85bar.Structural detail or housing bottom change due to pressure load
And it deforms, moulding, distort, arching upward or curved region is also known as " respiratory region ".
In addition, for example when filling up compressor with refrigerant, low-pressure area pressure close to zero so that structural detail or shell
Body bottom can also towards " direction in addition " or internally deformation, moulding, distort, arch upward or be bent because atmospheric pressure is higher.And
Low-pressure area can for example load the test pressure of 150MPa or 15bar.
For control system, coldplate particularly axially, i.e. substantially normally in the face of coldplate and structural detail, it is excellent
Choosing is spaced apart only by spacer element.Here, the transmitting of deformation toward the coldplate of structural detail at least exists relative to coldplate
Flat fastening on shell is reduced or prevents.
Coldplate can especially be arranged to laterally especially slight mobile relative to spacer element." lateral " is appreciated that
