Patent ID: 7621150

Claim:
An air conditioning assembly for cooling comprising; a compressor for compressing refrigerant, a gas cooler for cooling and condensing refrigerant from said compressor, an expansion device for expanding refrigerant, an evaporator for evaporating the refrigerant from said expansion device, a heat exchanger having a hot passage for the flow of refrigerant therethrough from said gas cooler to said expansion device and a cool passage for the flow of refrigerant therethrough from said evaporator to said compressor for exchanging heat between said passages, said gas cooler including an inlet header being circular in cross section and extending along a first axis and in fluid communication with said compressor and an outlet header being circular in cross section and extending along a second axis parallel to and spaced from said first axis and a plurality of condensing tubes extending between said headers for conveying refrigerant therebetween, said heat exchanger including a first tank being circular in cross section and extending along said first axis from said inlet header and a second tank being circular in cross section and extending along said second axis from said outlet header and at least one hot tube extending between said tanks to define said hot passage and at least one cool tube extending between said tanks to define said cool passage, at least a portion of each of said tanks being an extension of said respective axially aligned header, at least a portion of each of said tanks being integral with said respective axially aligned header, a partition dividing each of said tanks into a hot chamber and a cool chamber, an inlet separator for separating the interior of said inlet header from at least one of said hot chamber and said cool chamber of said first tank, an outlet separtor for separating the interior of said outlet header from at least one of said hot chamber and said cool chamber of said second tank, said hot tube extending between said hot chamber of said first tank and said hot chamber of said second tank and said cool tube extending between said cool chamber of said first tank and said cool chamber of said second tank, and a homogenous cylinder defining each of said headers and at least an axially aligned and associated portion of one of said tanks.
