Electrical compressor housing comprising a dissipation device, and compressor including such a housing

Abstract

The invention relates to a housing 1 of an electrical compressor for a refrigerant circuit, comprising a wall 2 suitable for delimiting a first volume of the compressor in which the refrigerant circulates relative to a second volume of the compressor into which a control device of the electric motor extends, a first face of the wall 2 facing the second volume being configured to receive the control device while a second face 4 of the wall 2 facing the first volume comprises a heat dissipation means 5, characterized in that the heat dissipation means 5 takes the form of a plurality of tubular elements 6 originating from the second face 4.

1 . A housing of an electrical compressor for a refrigerant circuit, comprising:
 a wall suitable for delimiting a first volume of the compressor in which the refrigerant circulates relative to a second volume of the compressor into which a control device of the electric motor extends,   a first face of the wall facing the second volume being configured to receive the control device while a second face of the wall facing the first volume comprises a heat dissipation means,   wherein the heat dissipation means takes the form of a plurality of tubular elements originating from the second face.   
     
     
         2 . The housing according to  claim 1 , wherein at least one tubular element is formed by a solid tube of circular section made of the same material as the wall. 
     
     
         3 . The housing according to  claim 1 , wherein at least one tubular element extends along an axis perpendicular to a first plane in which the second face is inscribed. 
     
     
         4 . The housing according to  claim 3 , further comprising a peripheral edge formed by a first portion which emerges from the second face of the wall and a second portion which emerges from the first face of the wall, a length of the tubular elements measured on the perpendicular axis being less than a length of the first portion, measured on this same axis. 
     
     
         5 . The housing according to  claim 4 , wherein a bushing suitable for receiving a rolling bearing, emerges from the second face of the wall. 
     
     
         6 . The housing according to  claim 5 , wherein the bushing is terminated by an end which is inscribed in a second plane separated from the first plane in which the second face is inscribed by a distance less than the length of the first portion of the peripheral edge. 
     
     
         7 . The housing according to  claim 6 , wherein the length of at least one tubular element is less than the distance which separates the second plane from the first plane. 
     
     
         8 . The housing according to  claim 4 , wherein the plurality of tubular elements is distributed on the second face around the bushing. 
     
     
         9 . The housing according to  claim 2 , wherein the wall comprises a through orifice suitable for receiving an electrical connector linking the control device to the electric motor. 
     
     
         10 . The housing according to  claim 1 , further comprising a flank formed on the periphery of the wall. 
     
     
         11 . The housing according to  claim 10 , wherein the flank comprises a first through hole arranged to receive a high voltage electrical power supply connector and a second through hole arranged to receive an electrical signal connector. 
     
     
         12 . A compressor for a refrigerant circuit comprising a unit formed by a compression mechanism coupled to an electric motor, said compressor comprising a housing according to  claim 1 . 
     
     
         13 . The compressor according to  claim 12 , comprising a high voltage electrical power supply connector installed in a first hole passing through a flank of the housing, and an electrical signal connector installed in a second hole passing through said flank. 
     
     
         14 . The compressor according to  claim 12  comprising a refrigerant inlet orifice arranged on the compressor so that the refrigerant circulates between the tubular elements.
