Definitions
- the invention relates to a cold part of a cryocooler according to the preamble of claim 1.
- Miniature coolers use a motor-driven compressor to create a cyclical change in the working volume of a pressurized, gaseous refrigerant. As part of the working volume, the refrigerant flows through a closed cylinder of the cold part, the so-called cold finger. Inside the cold finger is a piston-shaped one
- Regenerator which has openings at both ends through which the refrigerant can flow.
- the regenerator moves with a phase shift of approx. 45-90 ° to the pistons of the compressor.
- the refrigerant passes the regenerator in alternating directions. It flows from the compressor side of the cold finger through the regenerator into the expansion space and back again. During this cyclical movement of the regenerator and the refrigerant, heat is released to the environment on the compressor side of the cold finger and heat is extracted from the expansion side of the cold finger.
- the object to be cooled generally an electronic component, is arranged on the outside of the cold end of the cold finger in such a way that the thermal energy of the component is released to the refrigerant through the outer wall of the cold finger.
- a cold part of a cryocooler with a piston-shaped regenerator which has openings at both ends through which a refrigerant can flow, and a closed cylinder, in which the regenerator moves cyclically with an upper and lower layer, with a heat exchanger arranged on the end it is provided that the inside of the heat exchanger and the end of the regenerator facing the heat exchanger are finned in such a way that the fins engage in the upper position of the regenerator.
- the fins of the heat exchanger and the regenerator have a trapezoidal cross section.
- Figure 1 shows a split Stirling cooler in cross section.
- Figure 2 shows the cold end of the cold part in detail. The invention is explained below using an exemplary embodiment with the aid of the figures.
- FIG. 2 shows the cold end 7 of the cold part 3 of the split Stirling cooler 1 from FIG. 1 in detail.
- a motor-driven compressor 2 generates a cyclical change in the working volume of a pressurized, gaseous refrigerant 11.
- a connecting line 4 connects the compressor of the split-Stirling cooler to the cold part 3.
- the compressor and cold part can also be structurally be united.
- the refrigerant 11 flows through a closed part of the working volume
- Cylinder of the cold part the so-called cold finger 3.
- a piston-shaped regenerator 5 which has openings at both ends through which the refrigerant 11 can flow.
- the regenerator 5 moves depending on the design with a phase shift of 45 to 90 ° to the pistons 12 of the compressor 2 in the cylinder of the cold finger 3 and thus causes the refrigerant 11 to pass the regenerator 5 in alternating directions.
- the refrigerant 11 therefore flows from the compressor side 8 of the cold flow through the regenerator 5 into an expansion space 6 and back again.
- the compressor side 8 of the cold finger 3 becomes warmer than the environment and the
- the refrigerant extracts heat from the expansion side 7 of the cold finger and releases it to the environment on the compressor side of the cold finger.
- the object to be cooled for example an electronic component, is arranged on the outside of the cold end of the cold finger in such a way that a heat flow from the object is absorbed by the refrigerant through the outer wall of the cold finger.
- the cylinder of the cold part on the side of the expansion space is closed at the end with a heat exchanger 10.
- the shape of the fins 9, 13 is selected such that the fins 9 at the end of the regenerator and the fins 13 on the inside of the heat exchanger in the expansion-side end position of the regenerator 5, ie when the regenerator 5 is the smallest distance occupies to the heat exchanger 10, interlock, but do not touch. This avoids that between the inside of the heat exchanger
- the effective area for the heat flow of the heat exchanger 10 is effectively increased by the fins without increasing the volume of the refrigerant 11 enclosed between the inside of the heat exchanger 10 and the end of the regenerator 5.
- the cross sections of the ribs 9, 13 are trapezoidal. This will be another
- the invention is not limited to the embodiment described above with a split Stirling cooler.
- the invention is also suitable for other cryocoolers which have a cold part with a regenerator piston.
