A heat exchange unit includes a heat exchanger, a structure supporting the heat exchanger, an insulating member electrically insulating the heat exchanger from the structure, a compressor electrically connected to the heat exchanger and the structure, and a connection member attached to the heat exchanger. The connection member electrically connects the heat exchanger and the structure. The connection member is provided separately from a first conductive path that electrically connects the compressor and the heat exchanger, and a second conductive path that electrically connects the compressor and the structure.

Particular embodiments described herein provide for an electronic device that can be configured to include a substrate, a heat source on the substrate, and a heat pipe. The heat pipe includes a plurality of bumps that extend from the heat pipe towards the substrate but do not come into contact with the substrate. The bumps are configured to help mitigate radio frequency interference in the electronic device. More specifically, the bumps can be configured to provide a resonant frequency in a specific radio frequency band and act as a radio frequency filter.

A method of induction welding a first thermoplastic composite (TPC) to a second thermoplastic composite (TPC) includes inductively heating a weld interface area between the first TPC and the second TPC, and cooling a surface of the first TPC opposite the weld interface area while inductively heating the weld interface area.

A flow-guiding rod includes a cooling channel provided in a rod portion of the flow-guiding rod, and a coolant inlet pipe and a coolant outlet pipe provided on end(s) of the flow-guiding rod. The coolant inlet pipe and the coolant outlet pipe are communicated with the cooling channel.

An electrostatic precipitating apparatus for a cooling tower is provided. The precipitating apparatus include an electrostatic precipitator including a plurality of discharge electrodes to which a voltage is applied and a plurality of electrostatic precipitating electrodes each disposed between the discharge electrodes and grounded, a washing water supply spraying the washing water to the electrostatic precipitator, and a frame assembly supporting the electrostatic precipitator. The electrostatic precipitator includes a first setting beam having a plurality of lower slots into which the discharge electrodes are fixedly inserted, and the frame assembly includes a lower frame extending in a stacking direction of the discharge electrodes to support the first setting beam, via which a voltage is applied to the discharge electrode.

The application relates to a high-efficiency phase-change condenser for a supercomputer, including a condenser box body, a refrigerant input pipe, a refrigerant output pipe and a condensing coil; a liquid refrigerant accommodated in the condenser box body, and a gas-phase region existing between a liquid level of the liquid refrigerant and a top of the refrigerant box body; one portion of the condensing coil immersed into the liquid refrigerant, and the other portion of the condensing coil located in the gas-phase region above the liquid level of the liquid refrigerant; and in the gas-phase region, refrigerant vapor bubbles are liquified by the condensing coil. Liquid-phase and gas-phase saturated refrigerants can be completely condensed by the condensing coil in a limited condenser space, thereby improving heat exchange efficiency of the condenser.

In one instance, an isolator for a heating, ventilating, and cooling (HVAC) system is provided that is a formed plastic member that is disposed between dissimilar metals of the bottom of the condenser and a base pan that supports the condenser or between two dissimilar metals of another HVAC heat exchanger. The isolator separates the two dissimilar metals involved from each of those components and also provides gaps or apertures to drain any water that otherwise might become standing water that potentially causes oxidation or increased oxidation. Other aspects are disclosed.

A cooling apparatus for a medium voltage or high voltage switchgear includes an evaporator, a fluid conduit, and a condenser. The evaporator is configured to surround at least part of a current carrying contact. The fluid conduit fluidly connects the evaporator to the condenser. A section of the fluid conduit is formed within the evaporator and is electrically insulating and is configured such that fluid can contact an outer surface of the current carrying contact. The cooling apparatus is configured such that in use a working fluid in the evaporator is heated to a vapour state, and the vapour is transferred by the fluid conduit to the condenser. The vapour in the condenser is condensed to the working fluid. The condensed working fluid is passively returned via the fluid conduit to the evaporator.

Provided is a solvent separation method and a solvent separation apparatus that make it possible to efficiently retrieve the thermal energy possessed by an exhaust atmosphere released in a solvent-removal step to suppress reductions in a temperature of the exhaust atmosphere. In the solvent separation method and the solvent separation apparatus, a vaporized solvent is removed from a gas while heat exchange between the gas within a condensation part and the gas within a dust-collection part is conducted by using a heat exchange part that is placed between the condensation part that introduces the gas into a first direction and the dust-collection part that introduce the gas into a second direction opposite to the first direction the gas discharged from a downstream side of the condensation part.

A heat pipe assembly includes walls having porous wick linings, an insulating layer coupled with at least one of the walls, and an interior chamber sealed by the walls. The linings hold a liquid phase of a working fluid in the interior chamber. The insulating layer is directly against a conductive component of an electromagnetic power conversion device such that heat from the conductive component vaporizes the working fluid in the porous wick lining of the at least one wall and the working fluid condenses at or within the porous wick lining of at least one other wall to cool the conductive component of the electromagnetic power conversion device. The assembly can be placed in direct contact with the device while the device is operating and/or experiencing time-varying magnetic fields that cause the device to operate.
