According to various, but not necessarily all, examples of the disclosure there is provided an apparatus comprising: one or more portions of material configured to vibrate at one or more ultrasonic frequencies when the material is positioned within a varying magnetic field; and wherein the one or more portions of material configured to vibrate at one or more ultrasonic frequencies are positioned so that, when a varying magnetic field is applied to the apparatus, the vibration caused by the varying magnetic field provides increased cooling within a cooling system.

A thermal control system includes an enclosure configured to contain a thermal mass. A baffle plate is disposed in the enclosure. A heat exchanger is coextensive with and cooperates with the baffle plate to divide the enclosure into a first chamber and a second chamber. An air circulation element cooperates with the baffle plate and the heat exchanger to define an air circulation path and to cause air to flow through the air circulation path. The heat exchanger exchanges thermal energy with the air flowing through the air circulation path.

A cooling system, includes: an evaporator configured to take heat from a heat source by latent heat of evaporation of liquid; an aspirator configured to suck vapor generated in the evaporator and decompress an inside of the evaporator; a liquid supplying unit configured to supply liquid to the aspirator and the evaporator; and a gas mixing unit configured to mix gas into the liquid to be supplied from the liquid supplying unit to the evaporator.

An air-cooled heat exchanger (ACHE) for cooling process fluids used in an industrial process. In one embodiment, the ACHE is configured as a forced-draft ACHE. A support structure supports the forced draft ACHE above grade. A tube bundle is supported by the structure and is configured to receive process fluids used in an industrial process. A plenum is connected to the support structure, positioned beneath the tube bundle and configured to direct air-flow through the tube bundle. A fan is supported by the support structure and positioned beneath the plenum. Rotation of the fan produces an air-flow that is directed through the tube bundle by the plenum. A fan drive system is supported by the support structure, positioned beneath the fan and comprises a permanent magnet motor comprising a motor casing, a stator and a rotatable shaft, the rotatable shaft being connected to the fan.

A heat-dissipation device and an electronic apparatus are provided. The heat-dissipation device includes a pump and a pipe. The pump includes a rotary portion and a driving portion. The rotary portion is disposed in the pipe, and the driving portion is operative to provide a rotary driving force to the rotary portion to circulate a cooling fluid within the pipe.

A heat dissipation device with forced coolant flow is provided which includes a base, coolant conduits, and a driving module. The conduit includes an inlet port, an extension segment, and an outlet port. The extension segment is connected to the base. The driving module includes a housing, a separating member, and two magnetic driving members. The separating member, being a thin magnetic plate, is positioned in the housing and defines a first chamber and a second chamber for coolant. The first chamber and the second chamber are connected to the inlet port and the outlet port and a flow of coolant can be initiated by alternating an electrical current feed to the two magnetic driving members on each side of the separating member.

An analyzing device includes a heating device, a cooling device, and a controller. The cooling device includes a piezoelectric pump, a check valve, an exhaust valve, and an air tank. The analyzing device heats a subject by the heating device. The cooling device drives the piezoelectric pump while the heating device heating the subject. With this, the outside air is sucked through a suction port and the air that is discharged from the piezoelectric pump is accommodated in the air tank through the check valve. Then, the pressure in the air tank is increased. Thereafter, the cooling device stops driving of the piezoelectric pump. With this, the air in the air tank is discharged toward the subject via the exhaust valve so as to cool the subject.

A cooling assembly for cooling a processor includes a heat sink base defining a first area and a second area, a plurality of heat sink fins extending from the first area, a thermoelectric cooling module having a cold side and hot side, wherein the cold side is in contact with the second area, and a heat sink module in contact with the hot side. In use, a method includes monitoring a processor parameter selected from processor power consumption and processor temperature, and causing airflow across the plurality of heat sink fins and the heat sink module. The method further includes powering on the thermoelectric cooling module in response to the processor parameter having a value greater than a first threshold value, and powering off the thermoelectric cooling module in response to the processor parameter having a value less than a second threshold value.

3D printed thermal management devices and corresponding methods of manufacturing are described herein. A thermal management device includes a single contiguous component including at least a portion of a first heat exchanger and at least a portion of a second heat exchanger. The second heat exchanger is of a different type than the first heat exchanger.

An apparatus and method for melting snow and/or ice on a vehicle comprises a precipitation sensor, a surface temperature sensor, an ambient temperature sensor, a heater, and a programmable controller. The programmable controller comprises a memory unit to store a cut off surface temperature Tc, and a set of program modules. The programmable controller further comprises a processor to execute the set of program modules. A heater control module, executed by the processor, is configured to deactivate a heater based on a surface temperature being greater than the cut off surface temperature. Further, heater control module is configured to activate the heater based on an ambient temperature being lower than freezing point of water and precipitation being present outside the vehicle, thereby melting snow and/or ice on the vehicle. The snow melts off because of heat generated by the heater upon activation.
