Abstract: The present invention provides a refrigeration system for compact equipment, particularly of the type including electronic circuits and internally provided with a heat source to be cooled, said refrigeration system including a heat dissipation device mounted in the equipment and including a heat absorbing portion, which absorbs heat from the heat source, and a heat dissipation portion accessible from the outside of the equipment and which releases the heat to the exterior of the equipment; and an auxiliary refrigeration circuit external to the equipment and having: a heat absorbing means to be selectively coupled to the heat dissipation portion so as to receive therefrom, by conduction, at least part of the heat received from the heat source and dissipated by said heat dissipation portion; and a heat dissipation means which releases the heat to the environment external to the equipment.

Abstract: The present invention pertaining to the field of refrigeration equipments was designed to allow an unexpected construction and operation, and which is more efficient than the one achieved by using existing similar equipments. It is consisted of a compressor (1) comprised of a shell (2) within which it is located a compression cylinder (3), whereas from the shell (2) it is projected an inlet tube (5) from an evaporator and a discharge tube (6), which conducts the fluid into a condenser; at least one pre-condenser (7) associated with the compressor (1), the pre-condenser (7) being fed by a tubing (8) from the compression cylinder (3) located within the compressor (1), and equipped with an outlet tube (11); and a heat exchanger (91) internal to the outer region of the compressor (1) and cooperative with the pre-condenser (7) through the outlet tube (11) of the pre-condenser (7), the heat exchanger (91) comprising tubes attached around the shell (2) of the compressor (1).
