Abstract

The invention concerns a compressor housing comprising an upper shell (4) and a lower shell (1) assembled at a peripheral weld seam (3). At least one shell extends from the center of the housing beyond the weld seam (3) outwards and upwards.

Description

Compressor housing

The present invention relates to a kind of coolant compressor housing, be particularly useful for the compressor that in the family expenses refrigerating plant, uses.This compressor housing is for example open by DE 20209839 U1.

The conventional compression engine housing partly is made up of two shells, and these shell parts are welded and surround compressor each other hermetically.On the one hand for cooling compressor, on the other hand in order to remove in refrigerating plant inside the condensed water that in operate as normal, produces regularly, on the upper case of housing, be equipped with a container for evaporation, condensed water be directed in this container for evaporation and in this container for evaporation the used heat by means of compressor make this condensate evaporation.

Only when the bottom of condensed water container very closely abuts on the upside of arching of housing shell on top, just can be effectively be delivered to condensed water and thus effectively cooling compressor and evaporation condensed water from the housing shell heat.In order to guarantee form fit closely, the housing shell on the bottom of condensed water container and top must be with the close tolerance manufacturing, and this and cost interrelate.

Task of the present invention is, a kind of housing that is used for compressor is provided, this housing in manufacturing cost minimum and to guarantee under the low situation of the dimension precision requirement of shell part stable effectively and work ground cooling compressor or evaporation condensed water.

This task solves by a kind of like this compressor housing, this compressor housing has a upper case and a lower case, this upper case and this lower case one around the seam position on be connected to each other, in this compressor housing, at least one outwards and is upwards stretching out above the seam position in the radial direction in these shells.Produce a depressed part by this moulding on the upside of compressor housing, the wall of this depressed part directly can receive condensed water by shell formation and this depressed part of compressor housing.As the tradition evaporation shell of self member saving and the shell of condensed water and compressor housing direct contact guarantee with manufacturing variation possible aspect the hull shape shape irrespectively effectively with the heat transferred condensed water and thus assurance cool off effectively and evaporate.

According to one first configuration, lower case is stretched out above the seam position and is connected with the outward flange of upper case on this seam position, thus, the wall part of the depressed part of current formation constitutes by stitching the part of stretching out at the position surpassing of lower case by a upper case and a part.

According to one second configuration, upper case surpasses that the seam position is stretched out and is connected at the outward flange of this seam position up and down portion shell.In this case, upper case limits the border of depressed part separately.

Preferred seam position form one around the position, deep of the groove that is open upwards.

Under the different situation of shell height, especially under the lower case situation higher than upper case, compressor is pre-assembled especially well.

Other features and advantages of the present invention draw from the following explanation of embodiment being carried out by means of accompanying drawing.Accompanying drawing is represented:

The schematic cross section of Fig. 1 compressor housing of first configuration according to the present invention;

The details of the amplification among Fig. 2 Fig. 1;

The schematic cross section of second configuration of Fig. 3 housing; And

Fig. 4 is with respect to Fig. 3 details of the amplification of the configuration of modification a little.

Housing shown in Fig. 1 is made up of a shallow lower case 1 and a upper case 4, be welded with a plurality of fixing feet 2 that are used for compressor housing is assemblied in refrigerating plant on the outside of this lower case, this upper case is connected by the outward flange of weld seam 3 with lower case 1.Upper case 4 peak from central authorities in section outwards extends up to weld seam 3 and at first crossing weld seam 3 continuation extension downwards in the radial direction, so that finally stretch upwards with downward again.Upper case 4 therefore form one be open upwards around groove 5, this groove can receive condensed water to be evaporated.

In this configuration, the deepest point 6 of groove 5 is being positioned at outside the weld seam 3 with such segment distance in the radial direction, make when water level is low water in the groove 5 do not contact upper case 4 be positioned at weld seam 3 with the zone and therefore only by faint heating.When water level rises, because the trend that the interior zone of shell 4 stretches upwards gradually towards central point, water spreads on this interior zone more and more widelyer, and one side makes heat be delivered to the efficient of water and makes operational evaporating surface increase strongly on the other hand thus.Therefore, evaporation rate is along with water level also rises, and overflow is avoided.

Shown in the details amplifier section of Fig. 2, in upper case 4, on the height of weld seam 3, form one around groove 7, the edge of lower case 1 inserts in this groove.Therefore, just determined the relative position of shell 1,4 before welding, and can easily guarantee: these shells can contact on the whole periphery of lower case 1 and can be welded hermetically.

Fig. 3 represent second configuration according to the present invention compressor housing with the similar section of Fig. 1.Lower case 1 illustrates in this form with jar, and this jar has shallow bottom and have the sidewall 8 that stretches upwards, extends to external diffusion precipitous in lower area in upper area, but this lower case also can have the bottom of arching as shown in fig. 1; The jar shape of Fig. 3 also can correspondingly be transformed into the configuration of Fig. 1.

Top section upper support in the expansion of sidewall 8 upper case 4 of an arching; The edge of this upper case welds mutually with sidewall 8.The uppermost region that is in weld seam 3 tops of sidewall 8 with upper case 4 limit one around the border of groove 5, this groove receives condensed water.Because the arching shape of shell 4 is the same with the Free Surface of water---evaporate on this Free Surface, the water in the groove 5 directly also increases along with water level rises at this by upper case 4 heated those areas.

In this configuration, the position, deep 6 of weld seam 3 and groove 5 overlaps, and thus, also directly is heated by upper case 4 even the water level in groove 5 is arranged in the water of this groove when low.

Fig. 4 shows the ambient conditions of weld seam 3 in the configuration of modification a little with respect to Fig. 3 with the section of an amplification.At this, the sidewall 8 of lower case 1 is vertical except that shoulder 9 basically, and this shoulder is connected two slightly different wall sections of diameter and uses as bearing, and upper case 4 is welded on this bearing.
