Definitions

  • the openings 5 and 14 are both released by the shutters 15 and 16 respectively.
  • Part of the flow rate of the fluid entering the chamber, 6 through the opening 14 follows the same path as in FIG. 3, along the arrow f1 from the chamber 6 to the fluid box 2 through the tubes 10 and along the arrow f2 from the fluid box 2 to the chamber 8 via the tubes 11, while the rest of the flow passes directly from the chamber 6 to the chamber 8 through the opening 5, according to the arrow f3.
  • This last part of the fluid is practically not cooled by its passage through the radiator, which limits the efficiency of the latter.
  • the fraction of the flow passing through the tubes, and consequently the cooling efficiency gradually increases when the rod 18 moves from the position of FIG. 1 to that of FIG.
  • the tubes of the bundle 103 are divided into three sub-assemblies 110, 111 and 124, the tubes of the sub-assembly 110 connecting the chambers 106 and 122, those of the sub-assembly 111 connecting the chambers 122 and 108 and those of the sub-assembly 124 connecting the chambers 108 and 123.
  • the stop 228 is moved away from the bush 227 and the spring 226 applies the shutter 215 to the opening 205 in order to close the latter.
  • all of the coolant entering the chamber 206 through the opening 214 runs through the tubes of the subassembly 210 to reach the fluid box 202 from which it emerges through the outlet pipe 209
  • the rod 218 pushes the sleeve 227 through the stop 228, compressing the spring 226, and the shutter 215 moves away from the opening 205.
  • a fraction of the cooling fluid can thus penetrate through the latter into the chamber 208, so that the fluid traverses all of the tubes of the bundle 203 (arrows F205) to reach the fluid box 202.
  • the radiator then operates in a circulation configuration "at I".
  • all of the fluid entering the radiator circulates in the cooling tubes of the sub-assembly 210.
  • the heat exchange surface is significantly reduced compared to the configuration in FIG. 9.
  • the limitation of the number of tubes traversed leads to an increase in the hydraulic pressure drop through the radiator and consequently to a modification of the distribution of the flows in the circuit to the detriment of that -this.
