Definitions

  • the present invention concerns a cooling plate particularly suitable for coupling with a frequency converter.
  • the invention also concerns a compressor fed by a frequency converter and equipped with the above mentioned plate for cooling the converter itself.
  • the above mentioned heat dissipation element is a coil pipe with uniform diameter, in which said cooling fluid circulates and which is arranged in contact with the hot components of the converter.
  • a dissipation plate is added, interposed between the coil and the converter in order to increase the heat exchange surface between the two elements.
  • the overall dimensions of the converter and of the relevant heat dissipation element generates a further drawback represented by the fact that it makes it difficult to install a converter in a pre-existing system that is not equipped with such a device.
  • the above mentioned integration makes it possible to reduce the complexity of the system in which the compressor is inserted.
  • the compact size offers a further advantage, represented by the fact that the compressor of the invention can be used in existing systems and replace a compressor without converter, with no need to make major changes to the system.
  • FIG. 1 shows an axonometric, partial section view of the compressor that is the subject of the invention
  • the above mentioned duct assembly 10 is developed between an inlet opening 7 and an outlet opening 8, which define an outflow direction V of the cooling fluid along the duct assembly 10.
  • the cross section of the duct assembly 10 can be defined in such a way as to force the fluid to flow at a fixed uniform or variable speed, in order to obtain in any case the maximum heat removal efficiency in each group of ducts 12, 13, 14. Therefore, the duct assembly 10 with increasing cross section gives the cooling plate 6 higher heat exchange efficiency compared to the heat dissipation elements of known type, thus achieving the object of the invention. Consequently, to advantage, the plate 6 of the invention requires a lower cooling fluid flow rate compared to the known heat dissipation elements, with the same heat flow to be dissipated.
  • the average difference between the temperature of the plate 6 and that of the fluid along the duct assembly 10 is minimal.
  • thermodynamics we have a condition that is analogous to that of a countercurrent heat exchange between two fluids that, as is known from thermodynamics, allows the maximum heat exchange efficiency to be obtained with the same fluid flow rate.
  • the outlet opening 8, 32 of the plate 6, 30 communicates with the variable volume chamber 5a, so that the fluid flowing out of the plate 6, 30 flows back in the main circuit of the system directly at the level of the variable volume chamber 5a.
  • the plate and the compressor that are the subjects of the invention achieve all the set objects.
  • the invention achieves the object to produce a cooling plate that is more efficient than the heat dissipation elements of the known type, thus making it possible to limit the overall dimensions of the plate itself.
  • the invention achieves the object to produce a compressor with frequency converter that is more compact than the analogous compressors of known type.

Abstract

L’invention concerne une plaque de refroidissement (6 ; 30) pour un convertisseur de fréquence (4), comprenant une surface (6a) adaptée à l'accouplement avec le convertisseur de fréquence (4) et un ensemble conduit (10) qui se développe entre une ouverture d'admission (7) et une ouverture d’évacuation (8 ; 32), entre lesquelles il est possible d’identifier une direction d’écoulement (V) d’un liquide de refroidissement le long de l’ensemble conduit (10). La zone de surface de la section transversale de l'ensemble conduit (10) augmente le long de la direction d'écoulement (V).
