摘要： Apparatus and method for sub-ambient cooling using thermoelectric element dynamics in conjunction with pulsed electrical power and selectively enabled thermal coupling to the cold sink. In one form, Peltier devices are dynamically enabled using pulses of electrical power while the thermal path between the cold side of the Peltier device and the cold sink is selectively switched in relative synchronism between conductive states responsive to the dynamics of the Peltier device temperatures. Switched coupling of the thermal connection between the cold sink and the Peltier device materially improves efficiency by decoupling Joule heating and conductive heat transfer losses otherwise conveyed from the Peltier device. Preferable implementations utilizes MEMS to accomplish the selective thermal switching, whereby sub-ambient cooling capacity is increased by parallel operation of multiple Peltier devices and MEMS switches.

摘要： The objects of the present invention are to achieve year-round utilization of pollinating insects such as bumble bees and to provide a constant temperature box (1) to be employed for this purpose.
In order to achieve the objects, the temperature inside the nest box (2) for housing pollinating insects such as bumble bees is maintained within an optimal habitat environment temperature range throughout the year. In the constant temperature box (1) for maintaining the temperature within the optimal habitat environment temperature range, the temperature in the space where the nest box (2) for housing pollinating insects such as bumble bees is placed is maintained within the optimal habitat environment temperature range for pollinating insects such as bumble bees through a means for temperature control. In addition, the constant temperature box is provided with a means for access (15) to allow the pollinating insects in the nest box to come and go between the nest box and the outside.

摘要： A thermoelectric cooler controller (10), a thermal reference source employing the controller, a thermal reference source, and a thermal calibration system. The controller (10) controls the temperature of a thermoelectric cooler (15). The controller (10) includes a temperature sensor (16) coupled to the thermoelectric cooler (15) that provides a temperature feedback signal. An error amplifier (12) compares a temperature command (TEMP CMD) with a feedback signal and generates a positive polarity output current command signal (VCMD). A current driver (13) is coupled to the error amplifier (12) for providing an output current equal to one-half the current command signal. An H-bridge circuit (14) is coupled between the current driver (13) and the thermoelectric cooler (15) for switching the direction of current flow in the thermoelectric cooler (15), thus heating and cooling it. A comparator (19) is coupled to the error amplifier (12) and the H-bridge circuit (14), for controlling the current supplied by the H-bridge circuit (14) to the thermoelectric cooler (15). The thermal reference source comprises the thermoelectric cooler (15) and the above-described controller. The detector system includes a detector (17), and the thermal reference source and controller. The thermal calibration system comprises the detector, the thermoelectric cooler for providing heat output to the detector, and the thermal reference source and controller.

摘要： A thermo-electric laser temperature control apparatus is driven by a switching mode control circuit (317, 315). Driving current polarity (via 321 or 322) determines if the thermo-electric apparatus (305) is operating in a heat absorbent or heat generating mode. A sequencing control circuit (361-364) is used in association with the control circuit to define operative ranges of the thermo-electric temperature control apparatus consistent with maintaining proper temperature for a linear operative range for the laser. Feedback circuitry permits precision control of the converter output to limit the operative temperature range of the laser to a small precisely defined temperature window.

摘要： A computer element performance enhancer (10) having a peltier device (32) providing cooling to the critical computer elements (22, 24, 26) of a desk top computer. A peltier device controller (50) regulates the flow of power to the peltier device (32) such that the critical computer elements (22, 24, 26) are maintained in a below ambient temperature range. An adjustable power supply (71, 72) is connected to and supplies power to the critical computer elements (22, 24, 26). A power supply controller (70) regulates the adjustable power supply (71, 72) such that a local voltage at the critical computer elements (22, 24, 26) is maintained at a precision high voltage range. A dual speed clock generator (122) is connected to the critical computer elements (22, 24, 26) and runs the critical computer elements (22, 24, 26) at a higher rate of speed when the critical computer elements (22, 24, 26) are within the prescribed temperature and voltage ranges.

摘要： A refrigerator may include a temperature sensor, a thermoelectric device module having a thermoelectric device, and at least one fan and configured to cool a storage compartment, and a controller that controls the output power of the thermoelectric device based on the temperature of the storage compartment, a set temperature, and the outside temperature. The output power of the thermoelectric device may be determined based on whether the temperature of the storage compartment is within a first temperature region including the set temperature, a second temperature region, or a third temperature region. In the first and second temperature regions, the thermoelectric device may operate at different output power and which gradually increases as the outside temperature increases. In the third temperature region, the thermoelectric device may operate at a third output power which exceeds the first output power and is greater than or equal to the second output power.
