Below with reference to the transition conduit 100 that be used for refrigeration plant of Fig. 3 to Fig. 8 description according to the embodiment of the invention.Wherein, refrigeration plant can be refrigerator or refrigerator-freezer.
As shown in Figure 3, transition conduit 100 according to the embodiment of the invention comprises entrance 110, the first silencer 120, middle part 130 and the second silencer 140, and wherein transition conduit 100 is integrally formed by entrance 110, the first silencer 120, middle part 130 and the second silencer 140.
Entrance 110 comprises first end (left end of the entrance 110 among Fig. 3) and the second end (right-hand member of the entrance 110 among Fig. 3).The capillary 200 of refrigeration plant is inserted in the transition conduit 100 by the first end of entrance 110.In one embodiment of the invention, entrance adopts and flattens forming technique formation.
Because capillary 200 is when eruption, the tube wall of excitation transition conduit 100 produces vibration, and eruption sound forms turbulent flow, forms noise.For above-mentioned noise is decayed, be connected with the first silencer 120 at the second end of entrance 110.The first silencer 120 comprises first end (left end of the first silencer 120 among Fig. 3) and the second end (right-hand member of the first silencer 120 among Fig. 3).The first end of the first silencer 120 links to each other with the second end of entrance 110, and the eruption sound that produces when being used for capillary 200 eruption is decayed.
Middle part 130 comprises first end (left end of the middle part 130 among Fig. 3) and the second end (right-hand member of the middle part 130 among Fig. 3), and wherein, the first end of middle part 130 links to each other with the second end of the first silencer 120.In one embodiment of the invention, middle part 130 adopts and flattens forming technique, can spray the sound that whistles to the capillary 200 through overdamping that is transmitted by the first silencer 120 thus and decay.As shown in Figure 3, the end of capillary 200 is inserted in the middle part 130 by entrance 110, the second silencer 120.That is, capillary 200 inserts the intubating length of transition conduit 100 greater than the length sum of entrance 110 and the first silencer 120, and less than the length sum of entrance 110, the first silencer 120 and middle part 130.
The second silencer 140 comprises first end (left end of the second silencer 140 among Fig. 3) and the second end (right-hand member of the second silencer 140 among Fig. 3).The first end of the second silencer 140 links to each other with the second end of middle part 130, can again decay to the eruption sound capillaceous through overdamping that is sent by middle part 130.
