摘要： A compact cryocooler includes a gas compression piston (304) supported for reciprocal linear translation along a first longitudinal axis (308) and a gas displacing piston (362) supported for reciprocal linear translation along a second longitudinal axis (366). The first longitudinal axis (308) and second longitudinal axis (366) are substantially orthogonal. A rotary motor (302) rotates a rotor (324) and associated motor shaft (320) about a motor rotation axis (328) disposed substantially parallel with the second longitudinal axis (366). Motor shaft (320) first and second mounting features (336, 340) traverse first and second eccentric paths around the motor rotation axis. A first drive coupling couples the first mounting feature (336) with the gas compression piston (304) and delivers a reciprocal linear translation along the first longitudinal axis (308) thereto. A second drive coupling couples the second mounting feature (340) with the gas displacing piston (362) and delivers a reciprocal linear translation along the second longitudinal axis (366) thereto.

摘要： An integrated sensor assembly (10) includes a gas compression unit (104) having a first longitudinal axis (308) and a gas expansion unit (112) having a second longitudinal axis (366) and the gas expansion unit is disposed with its second longitudinal axis orthogonal to the gas compression unit first longitudinal axis (308). A rotary motor (302) includes a rotor (324) supported for rotation with respect to a motor rotation axis (328) and the sensor assembly configuration is folded to orient the motor rotation axis substantially parallel with the second longitudinal axis (366). A motor shaft (320) extending from the rotor includes a first and second mounting features (336, 340) disposed substantially parallel with and radially offset from the motor rotation axis (328). A first drive coupling couples between the first mounting feature (336) and a gas compression piston (304) and drives the piston (304) with a reciprocal linear translation directed along the first longitudinal axis (308). A second drive coupling couples between the second mounting feature (340) and a gas displacing piston (362) and drives the piston (362) with a reciprocal linear translation directed along said second longitudinal axis (366).

摘要： Provided for an embodiment is a support member for a cryogenic cooler's expander. The support member provides stiffness to the expander to reduce movements at the expander's distal end and may increase the natural frequency of the expander. The support member may increase the natural frequency of the expander at least about two times in the bending and/or twisting sense. The bending natural frequency of the expander and support sub-assembly may be at least about two times greater or lower than the natural frequency of the electrical wires that connect an infrared sensor to a control processing unit to reduce the maximum stress applied to the electrical wires during use. In another embodiment, additional or redundant electrical pathways are provided for connections between the infrared sensor and the CPU. Furthermore, shock absorber and/or shock diverters are provided on rigid pins that connect the electrical wires to the CPU.

摘要： The present invention relates to a cryogenic cooler's expander supported by a support member, preferably a truncated conical tube. The support member provides additional stiffness to the expander to reduce movements at the distal end of the expander. The support member also increases the natural frequency of the expander. In one embodiment, the support member increases the natural frequency of the expander at least about two (2) times in the bending and/or twisting sense. In another embodiment, the bending natural frequency of the expander and support sub-assembly is at least about two times greater or lower than the natural frequency of the electrical wires that connect the infrared sensor to a control processing unit to reduce the maximum stress applied to the electrical wires during use. In another embodiment, additional or redundant electrical pathways are provided for the connection between the infrared sensor and the CPU. Furthermore, shock absorber and/or shock diverters are provided on the rigid pins that connect the electrical wires to the CPU.
