Abstract

A supercharging compressor for an internal combustion engine has an inlet port, an outlet port, a support body and an impeller that is coupled to the support body so as to rotate about an axis and is configured so as to draw in air from the inlet port and compress this air towards the outlet port when subjected to rotation; the compressor also has a Peltier cell cooling device, arranged between the inlet port and the impeller and provided with at least one Peltier cell, which has two faces, opposite each other, and is fed by means of electrical wiring to generate a difference in temperature and, thus, a transfer of heat between these faces in order to cool the air at the inlet to the impeller.

Dependent claims

A supercharging compressor for an internal combustion engine, comprising:

an inlet port,
an outlet port,
a support body,
an impeller coupled to the support body so as to rotate about an axis and configured so as to draw air from said inlet port and compress said air towards said outlet port when subjected to rotation;
a cooling device for cooling said air;
characterised in that said cooling device is a Peltier cell cooling device comprising at least one Peltier cell, that has a first face and a second face, opposite each other, and is powered by an electrical wiring to generate, in use, a difference in temperature between said first face and second face, and therefore a heat transfer from said first face to said second face;
said first face faced towards a passage through which said air flows.
