  • the component of the refrigerating fluid circuit such as the thermostatic pressure reducer 13 is no longer connected to the heat exchanger 1 via an integral terminal block as in the solutions of the prior art, but by means of a connection module affording flexibility in the orientation of the sensor 15 suitable for measuring for example the temperature or pressure of the second fluid FR injected into the heat exchanger 1 .
  • the support function of the component 13 of the refrigerating fluid circuit, in this case of the thermostatic pressure reducer 13 , and of the sensor 15 is split in two by means of the two fixing parts 19 , 21 , which can be assembled together with a different orientation of the fixing part carrying the sensor 15 .
  • a first fixing part 19 serves as a reference for the orientation of the second fixing part 21 carrying the sensor 15 .
  • the fixing parts 19 , 21 are therefore standard and it is upon assembly of the two fixing parts 19 , 21 that adaptation to the vehicle in which the heat exchange assembly will be incorporated is achieved.
