In order to reduce from compressor housing 1 to suction pipe 2 and 1 this heat transport significantly, comprise body elements 8 and make body elements 8 and suction pipe 2 and pressure tube 3 isolated at least one spacer element 7 according to connection set 9 of the present invention from pressure tube 3 to compressor housing.Therefore no longer directly contacting with suction pipe 2 or pressure tube 3 by body elements in the embodiments of the present invention 8, perhaps the contact area between these elements remains very little.
In order to reduce heat transport as much as possible, spacer element 7 preferably is made of than the worse material of body elements a kind of thermal conductivity.
In preferred embodiment according to Fig. 9, the cylindrical bubble foam glass body that is provided with between body elements 8 and suction pipe 2/ pressure tube 3 is used as spacer element 7, and wherein the multi cellular glass body is connected and is connected with body elements 8 on the other hand with suction pipe 2/ pressure tube 3 on the one hand with air tight manner.
For body elements 8 is fixed on the compressor housing 1 reliably, body elements 8 can be provided with contacting part 10, and it abuts on the inboard 12 of compressor housing 1 and is fixed in known manner, is soldering or is welding in the there.Contacting part 10 preferably body elements 8 obtain the integral part of its desired size with bending method or deep-draw method.Under the multi-hull type embodiment's of body elements 8 situation, contacting part 10 also can be made as soldering or is fusion welded to independent element on the cannula-like body elements 8.
In order further to reduce the heat transport between compressor housing 1 and suction pipe 2/ pressure tube 3, the diameter of attachment hole 5 is sized to that part of external diameter that passes attachment hole 5 greater than body elements 8.Therefore guarantee that the interface 11 of attachment hole 5 does not contact body elements 8, but spaced apart with body elements 8.Therefore form an annular space by this way between body elements 8 and interface 11, outside air can circulate therein and it can cool off connection set 9.
When being spacer element 7 when selecting suitable material, its thermal conductivity λ is particularly significant, and it defines when the temperature difference of 1K in the unit time by the heat of the layer of unit area and unit thickness and is unit with W/ (m*K).Yet copper (varying with temperature) has the higher thermal conductivity λ of ratio of about 380W/ (m*K), and the λ of non-alloyed steel approximately is 100W/ (m*K).By adding suitable alloying element such as chromium, nickel, manganese or molybdenum, the thermal conductivity λ of steel can be reduced to a large extent.For example, the Cr/Ni steel can have the thermal conductivity λ less than 20W/ (m*K).
Approximately only having material multi cellular glass thermal conductivity λ, that mentioned of 0.05W/ (m*K) is proved to be in test to being particularly advantageous.Therefore multi cellular glass has only big slightly than the air of 0.024W/ (m*K) λ value.
Similarly, stupalith particularly based on these materials of metallic oxide, has been proved to be very favorable in should be with the field.For example, can use so-called ceramic post sintering material or such as the technology material of the oxide ceramics of the high temperature sintering of making by aluminium, magnesium, beryllium or Zirconium oxide.
Preferably, but relate to the stupalith of soldering, make it possible to realize the perfect soldering of spacer element 7 and suction pipe 2/ pressure tube 3 on the one hand and the perfect soldering of body elements 8 or compressor housing 1 on the other hand, so that realize desired seal.
Except that the low heat conduction coefficient [λ=0.5-1.4W/ (m*K)] and corrosion resistance of stupalith, because refractory nature and the heat-resisting quantity and the shape stability of stupalith, stupalith is used in the insulation of suction pipe 2/ pressure tube 3 and its tie point on compressor housing 1, also has been proved to be particularly advantageous.
High temperature resistant and aging-resistant plastic materials also can apply described material by the suitable fixation such as contraction, bonding, laser, spray on every side or lamination at suction pipe 2/ pressure tube 3 as the material of spacer element 7.
Because its low heat conduction coefficient, on the contrary above-mentioned material cause from compressor housing 1 or from the body elements 8 that directly contacts with compressor housing to suction pipe 2 and from pressure tube 3 to body elements 8 and the heat transport of not expecting of compressor housing 1 strong reduction.
Austenitic steel is preferably as the material of body elements 8.In the art, austenitic steel is characterised in that the thermal conductivity that it has reduction and the alloy component (for example, Cr/Ni or Mg-alloy) of high corrosion stability, toughness and high temperature resistance.Simultaneously, this material also can make body elements 8 be airtight connected to compressor housing by welding.
Figure 10 shows the optional embodiment of connection set 9, and wherein, body elements 8 and spacer element 7 are designed to one-piece element.Spacer element 7 is designed to the end portion of body elements 8, and described end portion is extended obliquely with respect to the angled right angle that is preferably of the axis of suction pipe 2/ pressure tube 3, so that for example surround suction pipe 2/ pressure tube 3 by soldering or melting welding with air tight manner.
As according to as shown in the diagram of Figure 10, the internal diameter of canular body elements 8 is always greater than the external diameter of suction pipe 2/ pressure tube 3, make to form the air cushion (gaseous mixture, refrigeration agent) with insulation function between suction pipe 2/ pressure tube 3 and body elements 8, it has equally greatly reduced the heat transport between suction pipe 2/ pressure tube 3 and the compressor housing 1.Similarly, the end portion of body elements 8 also can be the element of making separately, and it is placed in the distolateral of cannula-like body elements 8 and goes up and encirclement suction pipe 2/ pressure tube 3.It is important in this that, owing to there is not the contact between body elements and suction pipe 2/ pressure tube 3, only through spacer element 7 produce from body elements 8 to suction pipe 2 and from pressure tube 3 to body elements 8 hot-fluid, wherein, body elements 8 and spacer element 7 are made in the mode of a plurality of parts integratedly or also.
As further illustrating among Figure 10, the end portion of body elements 8 is surrounded suction pipe 2/ pressure tube 3 on the part of its longitudinal extension, this part is positioned at the outside of attachment hole 5 or along the outside of the compressor housing 1 wall cross section on the periphery surface of the outstanding body elements 8 in normal direction side.Therefore the surface of contact of the end portion of body elements 8 and suction pipe 2/ pressure tube 3 is not set to directly be close to the surface of contact of body elements 8 with compressor housing 1, but apart from its distance at the promotion insulation function.
In order to surround suction pipe 2/ pressure tube 3 and to make it possible to be tightly connected with it, body elements 8 end portion that are designed to spacer element 7 are provided with a looping pit, and suction pipe 2/ pressure tube 3 is fixed on this looping pit inside hermetically.
Figure 11 illustrates another optional form of implementation of connection set.In this body elements 8 is not that the attachment hole 5 that is compressed engine housing 1 as mentioned above passes, but is set on the compressor housing 1 in the outside of this attachment hole 5 with surrounding this attachment hole airtightly.According to Figure 11, directly be fixed on the outside 13 of compressor housing 1 at the cross section of this body elements 8 by butt joint (Stumpf).But crooked for example 90 ° contact segment also can be set be used for fixed body element 8 more stably.Because body elements 8 is set on the inboard 12 of compressor housing 1 by this way, form the after ventilation space between suction pipe 2/ pressure tube 3 and body elements 8, the attachment hole 5 of this compressed engine housing 1 in after ventilation space is communicated with the surrounding atmosphere by arrow 15 expressions in compressor housing 1 outside and so can realizes the cooling effect that adds.The diameter of attachment hole 5 is designed to the diameter greater than suction pipe 2/ pressure tube 3 for this reason.
But abandoning under the situation of this cooling effect, body elements 8 equally also can be fixed on (not shown) on the outside 13 of compressor housing 1.
For in the application corresponding occasion, realize further making and thermal process aspect advantage, what can conform with purpose in case of necessity is to be designed to body elements and/or spacer element 7 multipart.The multi-hull type body elements 8 that comprises a plurality of elements that are engaged with each other has bigger flexibility aspect manufacturing and the surface Machining, and can be according to the special tectonic of requirement that exists and application realization connected system.
At last, Figure 12 shows the special embodiment of connection set 9, it comprises the spacer element of preferably being made by multi cellular glass, plastics or stupalith 7, and wherein, spacer element 7 is designed between just L shaped shape and interface 11 that be set directly at attachment hole 5 and suction pipe 2/ pressure tube 3.The shank 16 of spacer element 7 is surrounded and is compressed against on the outside 13 of compressor housing 1 by body elements 8 at this.If body elements 8 is connected with compressor housing 1 and suction pipe 2/ pressure tube 3 with air tight manner, then spacer element 7 needn't have tight function in this structure.Thereby the advantage that this structure provides is, also can use following material for spacer element 7, can only set up and being tightly connected of another kind of medium by these materials difficultly, particularly can not soldering or these materials of melting welding.
