Material.Specifically optional red copper material is to improve cold conduction efficiency.
2 cold end 21 of hot sound refrigerating machine is fixed in cold end fixation hole 111, when needing two or more thermoacoustic system
When cold 2 works together conduction cooling, need for hot sound refrigerating machine 2 to be installed in the form of centrosymmetric on cold bridge 1.Cold end fixation hole
111 can choose be made into through-hole or blind hole later according to actual conduction cooling demand and installation requirements balance；When hot sound refrigerating machine 2
When for even number, if cold end fixation hole 111 is made into through-hole, the cold end that is mounted on of 2 opposed type of hot sound refrigerating machine is fixed
It in hole 111, and needs to guarantee that cold bridge 1 is centrosymmetric with 2 entirety of hot sound refrigerating machine, that is, guarantees the same cold end fixation hole 111
Interior two hot sound refrigerating machines 2 and the generally symmetrical structure of cold end fixation hole 111, such mounting means may make hot sound refrigerating machine
2 vibration is offset.
When cold end fixation hole 111 is blind hole, then cold end fixation hole 111 is centrosymmetric distribution on cold bridge 2, it will be cold
The bottom 1111 of end fixation hole 111 is processed as fitting with warm-up motor 2, so that hot sound refrigerating machine 2 protrudes into cold end fixation hole 111
Part fitted closely with cold end fixation hole 111, guarantee cooling capacity aggregation.
The radiating end of hot sound refrigerating machine 2 is assembled in cold end fixation hole 111 in order to prevent, cooling capacity is neutralized, thermoacoustic system
2 cold end of cold, 21 end is concordant with 111 outside shell rim of cold end fixation hole, and hot sound refrigerating machine radiating end is placed in outside cold bridge 2
Side.One side of second heat exchanger 22 of hot sound refrigerating machine 2 close to 21 end face of cold end is the end of cold end 21, therefore further
, by the second heat exchanger 22 of hot sound refrigerating machine 2 close to the cold bridge in 111 outside of one side and cold end fixation hole of 21 end face of cold end
1 shell rim is concordant.
