Backg ound Art
[0002] The development of electric vehicles has brought new issues to the automotive field, in particular in view of the limited autonomy of the electric battery as well as the limited space that can be dedicated to the thermal management system at the bottom of the vehicles. For these reasons, it is more and more searched for compact and light thermal management systems.

[0003] This disclosure improves the situation.
[0004] It is proposed a refrigerant module for a thermal management system, comprising a refrigerant unit of two plates shaped to constitute channels for distributing refrigerant fluid in said thermal management system, at least one of the channels, called acoustic channel, comprising at least one muffler formed at least partially by at least one plate of said refrigerant unit.
[0005] Thanks to the integration of the muffler in the plates of the refrigerant module, the thermal management system is guaranteed to be more compact and lighter than in the state of the art, while ensuring reduction of noise and gas pulsation that are generated by a compressor of the thermal management system.
[0006] In another aspect, the muffler is formed by one plate of the refrigerant unit.
[0007] In another aspect, the muffler is formed by the two plates of the refrigerant unit.
[0008] In another aspect, the muffler has a general shape of a trapeze, or a cylinder or a parallelepiped or an ellipsoid.

Description of Embodiments
[0031] The present invention relates to a refrigerant module for a thermal management system, referred to as 1 in the figures. The refrigerant module comprises a refrigerant unit RU of a first plate 2 and a second plate 3, the two plates facing each other and fixed together.
[0032] The first plate 2 comprises channel tracks 4 and is later called refrigerant plate 2. The second plate 3 is essentially flat and is later called back plate 3. The refrigerant plate 2 and the back plate 3 are sealed together to delimit a closed space and to form the channels of the refrigerant module 1 . The channels ensure distribution of the refrigerant fluid in components of the thermal management system, like a compressor, an evaporator and a condenser (not shown).
[0033] Different components of the thermal management system can be attached to the refrigerant unit RU like at least: a condenser and/or a water condenser and/or a heat exchanger (evaporator and/or chiller) and/or PT (pressure temperature) sensors, and/or valves and/or AC (air conditioning) lines.
[0034] The refrigerant plate 2 comprises an inner side 6 and an outer side 7, cavities from the inner side 6 forming the channel tracks 4. The back plate 3 comprises an inner side 8 and an outer side 9. In the module 1 , the inner side 6 of the refrigerant plate 2 is disposed opposite to the inner side 8 of the back plate 3.
[0035] As can be seen from the figures, the refrigerant module 1 integrates a muffler 10 to reduce noise and gas pulsation from the compressor (not shown) of the thermal management system. The muffler is disposed within one channel of the refrigerant unit, called acoustic channel, 4a.
[0036] The integration of the muffler 10 to the refrigerant unit RU ensures the thermal management to be more compact and with less weight. [0037] The muffler 10 is formed at least partially by at least one of the refrigerant plate 2 and the back plate 3. The muffler 10 comprises a refrigerant inlet 1 1 , a refrigerant outlet 12 and a chamber 13 in between.
[0038] In figure 1 , the muffler 10 is formed partially by the refrigerant unit RU and comprises an insert 14 fixed to the acoustic channel 4a. In other words, in figure 1 , the muffler 10 can be defined as a box attached to the acoustic channel. This embodiment guarantees a simple process of manufacturing as well as an adaptability to any refrigerant unit.
[0039] In figures 2 to 8, the muffler 10 is completely formed by the refrigerant unit RU. In other words, the muffler 10 is integrally constituted by deformations 15 in the refrigerant plate 2 and/or the back plate 3. This embodiment guarantees a simple process of manufacturing and avoids any additional part, any additional sealing elements and any additional step of manufacturing.
[0040] In figure 3, only the refrigerant plate 2 comprises deformations 15 while in figure 4, both the refrigerant plate 2 and the back plate 3 comprises deformations 15.
[0041] The muffler 10 can be casted or shaped or forced or machined or stamped in at least one plate of the refrigerant unit. In other words, the deformations 15 are integral to the natural shape of the plates 2, 3.
[0042] As best seen from figure 5, a square section A of the refrigerant inlet 1 1 is of the same order as a square section A’ of the refrigerant outlet 12, preferably, A being equal to A’. On the other hand, a square section B of the chamber 13 is strictly larger than A, A’. The sharp increase of the square section (from A to B) followed by the sharp decrease of the square section (from B to A’) reduces gas pulsations from the compressor, hence, the noise generated by the compressor.
[0043] The muffler 10 can be of different shapes. It can be of the shape of a trapeze (figures 1 to 6 and 8), of a half-cylinder or a cylinder (figures 6 and 7) or of a parallelepiped or of an ellipsoid, depending on the amplitude and the frequency one wants to damp from the pulsations of the compressor.
[0044] For optimization of the space, the chamber 13 of the acoustic channel is located between two other channels, and the two other channels are at least partly adjacent to the chamber 13, preferably along the chamber from the refrigerant inlet to the refrigerant outlet. In other words, the other two canals border the chamber at least partly along the chamber and preferably from the refrigerant inlet to the refrigerant outlet.
[0045] The acoustic channel 4a can be in a discharge channel (figures 1 to 5) or a suction channel (figure 8). Also, the refrigerant module 1 can comprise a plurality of mufflers 10, as illustrated in figure 8.
[0046] The method of manufacturing is now described.
[0047] The method of manufacturing the refrigerant module 1 comprises a step of forming a muffler at least partially by at least one of the refrigerant plate 2 and the back plate 3 of the refrigerant unit in the acoustic channel 4a. [0048] When the muffler comprises the box, the method of manufacturing comprises a step of fixing the insert 14, for instance by brazing or welding.
[0049] When the muffler is fully integrated into the plates 2, 3, the method of manufacturing comprises a step of forming the deformations 15 by casting or shaping or forcing or machining or stamping at least one of the two plates of the refrigerant unit.
