cooler structure 1. 首先，通过作为冷却器1的一个元件的线性马达130也就是，定子130a和电枢130b的电磁相互作用，电枢130b开始线性运动，而固定到电枢130b的一端的活塞140做与电枢130b相同当经过散热部分200时，压縮的冷却剂气体通过散热部分200将一部分热量放射出冷却器1，并在经过置换器310之后被引入到热交换器330中。 First, the linear motor 130 as a cooling element 1 is, electromagnetic stator 130a and 130b interaction armature, the armature begins 130b linear movement of the armature is fixed to one end of the piston 130b of the armature 140 to make when the same radiating portion 130b through 200, the compressed coolant gas through the portion of the heat radiating portion 200 will emit a cooler, and is introduced into the heat exchanger 330 after passing through the displacer 310. 置换器310被线性移动到片簧160的弹性变形内的膨胀空间P， 其中置换器连杆320的一端被固定到片簧，并由于压縮的冷却剂气体的压力朝着冷却部分300变形。 310 is substituted into the linear movement of the leaf spring 160 is elastically deformed in the expansion space P, wherein one end of the displacer rod 320 is secured to the leaf spring, and due to the pressure of the compressed refrigerant gas toward the

space P due to the expansion of the coolant gas is cooled down to very low temperatures, and the expansion of the low-temperature coolant gas through the heat exchanger 330 again, and receives the heat exchanger 330 to be stored is introduced into the compression space C of heat. 由于膨胀空间P中膨胀的冷却剂气体减少的膨胀，通过片簧160的弹性恢复，置换器310 被移动回到压縮空间C。 Due to the expansion space P to reduce the expanded coolant gas expanded, restored by the elastic leaf spring 160, the displacer is moved back to the compression space 310 C. 通过重复再次压縮被引入到压縮空间C中的冷却剂气体的循环，完成执行冷却器1的冷却操作。 Is introduced into the compression space C circulating coolant gas is again compressed by repeated, to complete the cooling operation of the cooler. 现在，下面将详细描述作为冷却器1的一个元件的线性马达130。 Now, as a cooling element 1 of the linear motor 130 will be

core element 135. 特别的是，电枢130b包括空心圆柱形套管137和磁铁139。 In particular, the armature 130b comprises a hollow cylindrical sleeve 137 and the magnet 139. 空心圆柱形套管137由不锈钢构成，并具有该圆柱体一端上的上弯部分， 以直角被向外上弯到套管137，和该圆柱体的另一端上的弯曲部分145， 以直角被向内弯曲到套管137。 A hollow cylindrical sleeve 137 made of stainless steel, and has a bent portion on the upper end of the cylinder, the outwardly bent at right angles to the sleeve 137, and a curved portion 145 on the other end of the cylinder, is at right angles inwardly bent to the sleeve 137. 围绕弯曲部分145，提供了以相同间距间隔开的多个螺栓插孔146，以便通过使用小螺栓143和螺母144固定活塞140。 Around the curved portion 145, a plurality of bolts spaced apart at the same pitch receptacle 146, so by using a small bolt 143 and a nut 144 fixed to the piston 140. 此外，以均匀间距在套管137的圆周表面上形成长度中的缝隙138。 Further, a

integrally on both ends of the winding portion 132 ; a stator coil 134 wound on the coil winding portion 131 of the stator body 133; and a plurality of stator core 135, the stator body having a groove 136 formed on its center through, so that the coil 134 is adhesively secured to the winding having an outer circumferential surface of the stator body 133 of the coil 134. 图3是现有活塞组件的接合截面图。 FIG 3 is a cross-sectional view of a conventional piston engaging assembly. 如图3所示，在通过线性马达的电磁相互作用，电枢130b和活塞在定子130a内部线性往复运动的情况下，通过使用多个小螺栓143和螺母144，在电枢130b的末端上形成的弯曲部分145被固定到活塞140 的凸缘部分141以形成活塞组件，从而通过接收电枢130b的线性往复运动，活塞140可以做出与电枢130b相同的线性往复运动。 3, in the case of the linear motor by the electromagnetic interaction of the armature inside the stator 130b and the piston linearly reciprocates 130a, 144, 130b formed on the tip of the armature by using a plurality of small bolts 143 and nuts the curved portion 145 is secured to the flange portion 141 of piston 140 to form a piston assembly, so that by receiving a linear reciprocating motion of the armature 130b, the piston 130b of the armature 140 may be made of the same linear reciprocating motion. 为了形成上述结构的现有活塞组件，电枢130b和活塞140被放入手套箱（密封的透明箱），并戴着橡胶手套通过使用小螺栓143和螺母144，将活塞140的凸缘部分141和电枢130b的弯曲部分145彼此接合固定。 To form the above-described conventional configuration of the piston assembly, the armature piston 140 and 130b are placed in a glove box (sealed transparent boxes), and wearing rubber gloves by using small bolts and nuts 143, the flange portion of the piston 141,144,140 of and a curved portion 130b of the armature 145 is fixedly joined to one another. 然而，上述的接合方法很不方便并耗费时间，因为接合方法包括把多个小螺栓143分别逐个插入在活塞140的凸缘部分141以及电枢130b的弯曲部分145上形成的螺栓插入孔142、 146的处理，并且还要在小箱子内比如手套箱戴着橡胶手套逐个用螺母扣紧螺栓143。 However, the above-described bonding method is inconvenient and time-consuming because the bonding method comprises a plurality of small bolts 143 are inserted one by one in the flange portion 141 of piston 140 and a bolt 145 is formed on the bent portion 130b is inserted into the hole 142 of the armature, 146 process, and also in a small box, such as wearing rubber gloves, the glove box 143 by one fastening bolt with a nut. 此外，难于把螺母144固定到插入外部圆周表面的螺栓143，因为套管长且深。 In addition, it is difficult to insert the bolt nut 144 secured to the outer circumferential surface 143 of the sleeve as long and deep. 因此，活塞组件的现有的接合方法缺点在于降低了操作效率和产量，这是由于电枢130b和活塞140的困难和不方便的螺丝接合处理。 Thus, the conventional bonding method is disadvantageous in that the piston assembly operation efficiency and reduce the yield, which is due to the screw 130b of the armature and the piston 140 is difficult and inconvenient bonding process. 发明内容因此，本发明涉及一种活塞组件，其充分地克服由于现有技术的限制和缺点所带来的一个或多个问题。 SUMMARY OF THE INVENTION Accordingly,

the fixing member on the flange portion of the piston insertion hole is formed, and the magnet current is applied to the sleeve, so that the fixing member is fixed to the bent portion in contact with the magnet sleeve, the bolt is removed therefrom screws and, thus, compared to the prior art, the magnet sleeve according to the present invention and the bonding process of the piston easier, due to a simple process and reduces the time for the bonding process, reducing costs and improving productivity . 而且，现有的活塞组件经常是引起冷却剂污染的主要原因，因为使用的螺丝和螺栓留下了许多缝隙，并且在装配之后经常发生渗气穿过该缝隙污染冷却剂。 Further, the conventional piston assembly is often the primary cause of contamination of the coolant, as screws and bolts used left many gaps, and often occurs after passing through the slit assembly outgassing contamination coolant. 然而，根据本发明的活塞组件中则有很少或没有缝隙，因而防止了由于该原因的性能下降。 However, piston assembly according to the present invention there is little or no gap, thereby preventing performance due to the reason decreases. 在本发明中可以作出各种修改和变化，这对本领域技术人员而言是显而易见的是。 Various modifications and variations can be made in the present invention, it is apparent to those skilled in the art to Yes.
