    • The present invention relates to an integrated-type Sterling cryocooler, comprising two portions, namely, a compressor and an expander, wherein a housing of the compressor is designed in a way that an outer housing is provided around outside an inner housing to form a compression cavity, a piston is connected to a plate spring to support a reciprocating movement of the fixed piston to compress a gas, a coil is fixed between the interior of the housing and a bracket, a magnet is fixed between the bracket and a support, the bracket and the support are respectively connected to the housing, an interior of the expander is divided into two chambers, namely, an expansion chamber and a pneumatic chamber by a small piston and a heat regenerator which are fixed together, a cylindrical spring is disposed at a bottom of the expander, a groove is designed at a center of the compressor, the expander is embedded in the compressor, an orifice is designed on the bottom of the expander so as to be communicated with the compression cavity of the compressor. The present invention has a compacter structure and a smaller size and more facilitate extensive application thereof.
    • 本发明涉及一种包括两部分即压缩机和膨胀机的一体式Sterling低温冷却器,其中压缩机的壳体被设计成使外壳围绕内壳体设置以形成压缩 活塞与板簧连接以支撑固定活塞的往复运动以压缩气体,线圈固定在壳体内部和支架之间,磁体固定在支架和支架之间, 支架和支撑件分别连接到壳体,膨胀器的内部通过固定在一起的小活塞和热再生器分成两个腔室,即膨胀室和气动室,圆柱形弹簧设置在 膨胀机的底部,在压缩机的中心处设计有凹槽,膨胀机嵌入压缩机中,在膨胀机的底部设计有孔口,以便通讯 与压缩机的压缩腔一起使用。 本发明具有紧凑的结构和更小的尺寸,并且更有利于其广泛应用。
