A vending machine includes a vending machine main body, an internal heat exchanger, an external heat exchanger made of aluminum, and a compressor. The vending machine further includes an attachment base made of a steel plate and disposed on the base such that the external heat exchanger and the compressor are provided on the attachment base, and a pair of right and left holding members made of synthetic resin and engaging with and fixing to the attachment base, each having an accommodation unit corresponding to an outer shape at two sides of a lower portion of the aluminum external heat exchanger. The pair of right and left holding members forms a gap between the aluminum external heat exchanger and the attachment base such that the two sides of the lower portion of the aluminum external heat exchanger are accommodated and held in the accommodation units.

A compressor system is disclosed. The compressor system includes a motor, a compressor driven by the motor, a first after cooler, a second after cooler, and a heat exchanger housed in an enclosure. Interior panels are arranged in the enclosure to separate the motor and compressor, the first after cooler, the second after cooler, and the heat exchanger from one another. Conduit extends through the interior panels to provide a fluid path between the compressor, the first after cooler, the second after cooler, and the heat exchanger. Ducting is provided in the enclosure to provide fluid communication between various components of the compressor system.

A Multi Port Extrusion tubing (MPE tubing) (10) made from a Multi Port Extrusion (MPE), the MPE being a web like extrusion (Web-MPE) with two or more individual tubes (8) interlinked with webs (9). The webs have a thickness, which is less than the tube diameter of the individual tubes, and the MPE tubing includes at least one bending zone (A), and at least two straight zones (C1, C2). The web-MPE in the bending zone (A) is bent so that each individual tube has a U-shape, and the web-MPE in a first straight zone (C1) is parallel to the web-MPE in an adjacent second straight zone (C2). The web-MPE in the straight zones on each side of the bending zone (A) extend in substantially the same plane, so that all individual tubes of the web-MPE in the straight zones are parallel to each other, and extend in the same plane.
