Abstract: A device under test cooling system has a refrigerant line and a fluid line extending through a plurality of successively arranged heat exchangers. A digital scroll compressor has an intake for providing the refrigerant mixture to the compressor and a discharge connecting the compressor to the refrigerant line to provide the refrigerant mixture to the heat exchangers. The compressor includes a plurality of scroll elements between the intake and the discharge for compressing the refrigerant mixture. The compressor includes a valve configured to separate the scroll elements when in an open position to allow refrigerant to flow freely between the intake and the discharge. When the valve is in a closed position, the scroll elements compress the refrigerant. A controller is configured to switch the valve between an open and closed position based on a set duty cycle.

Abstract: A temperature control system and method include a source of a temperature control medium that is to be introduced into a space. A fluid line conveys the temperature control medium from the source to the space, a first end of the fluid line being disposed in the space. An orifice assembly has an orifice through which the cooling medium flows toward the space. A size of the orifice is adjustable such that a rate of flow of the cooling medium entering the space is controllable.

Abstract: A waterproof housing structure for portable optical analyzer mainly comprises a hard upper casing, a lower casing and a fastening element. The hard upper casing contains an outer rim and an inner rim. The lower casing contains a hard inner shell and a pliable cap. The hard inner shell has a trapezoidal rim which has a first trapezoidal surface and a second trapezoidal surface lower than the first trapezoidal surface. The pliable cap wraps a portion of outer surface of the hard inner shell, and has an outer edge and an inner edge mating the upper casing. The fastening element fastens the hard upper casing to the lower casing. Thus the two irregular rims and edges can be coupled to prevent liquid permeation. Fabrication and assembly during production or repair and maintenance are simpler. It also improves grasp feeling and anti-slipping effect on the handgrip of the portable optical analyzer.
