摘要： A vertical bundle air-cooled heat exchanger, a finned tube assembly for an air cooled condenser and method for forming the same, and a system for removing thermal energy generated by radioactive materials. In one aspect, an air cooled condenser sized for industrial and commercial application includes an inlet steam distribution header for conveying steam, a condensate outlet header for conveying condensate, an array of tube bundles each having a plurality of finned tube assemblies having a bare steel tube with an exposed outer surface and a set of aluminum fins brazed directly onto the tube by a brazing filler metal. The steel tubes may be spaced apart by the aluminum fins and have an inlet end fluidly coupled to the inlet steam distribution header and an outlet end fluidly coupled to the outlet header. A forced draft fan may be arranged to blow air through the tube bundles.

摘要： In accordance with the principals of the present invention, a cold tube is adapted to securely surround the beverage can, the cold tube utilizing high heat capacity/thermal mass to wick heat from the beverage in the beverage can. Contained within the cold tube, a plurality of fins are provided thus acting as a heatsink. The presence of the fins act as a heatsink by increasing convective, conductive, and radiative heat dissipation if used in the absence of the cold tube and conductive heat dissipation if used with the cold tube.

摘要： A refrigerator includes a vacuum insulated cabinet structure having an exterior wrapper with a plurality of exterior walls exposed to ambient conditions. One of the exterior walls includes an outer surface and an inset portion that is inwardly disposed relative to the outer surface of the exterior wall. A skin condenser system is disposed within the inset portion along an outer surface of the inset portion. The skin condenser system includes a coil array defined by a coil disposed in a coil pattern. The skin condenser system further includes a cover assembly covering the coil array and in thermal communication with the coil array to facilitate the dissipation of heat to the ambient surroundings.

摘要： In accordance with the principals of the present invention, a frozen tube is adapted to securely surround the can, the frozen tube utilizing high heat capacity/thermal mass to wick heat from the beverage in the can. Contained within the frozen tube, a plurality of fins are provided thus acting as a heatsink. The presence of the fins act as a heatsink by increasing convective, conductive, and radiative heat dissipation if used in the absence of the frozen tube and conductive heat dissipation if used with the frozen tube.

摘要： A heat exchanger includes a first fluid carrying conduit extending along a first conduit axis and configured to convey a first fluid at a first temperature, and a second fluid carrying conduit extending along a second conduit axis and configured to convey a second fluid at a cooler, second temperature. The heat exchanger also includes at least one fin having a first opening for coupling to the first fluid carrying conduit and a second opening for coupling to the second fluid carrying conduit. The at least one fin extends along a fin axis that subtends an acute angle or obtuse angle with at least one of the first conduit axis or the second conduit axis.

摘要： The present invention provides a threaded connecting member and a threaded connecting structure with a radiating function. Since a radiating passage which extends along a length direction of the threaded connecting member is provided on the threaded connecting member and the radiating passage runs through one end of the threaded connecting member to the other end of the threaded connecting member, when the threaded connecting member with the radiating function provided by the present invention is used, the threaded connecting member is provided in a connecting hole in a connector in a penetrating manner, the radiating passage communicates spaces on two sides of the connector, gas in the spaces on the two sides of the connector can perform heat exchange through the radiating passage and thereby the heat diffusion capability of a connected device is improved.

摘要： A heat exchange tube for an HVAC system can include at least one reduced diameter section with an integral flattened ridge. The flow of combustion gases through the heat exchanger tubes may be partially constricted inside the reduced diameter sections. When installed in an HVAC system the integral flattened ridges may be angled to intercept the flow of air outside the heat exchanger tubes.

摘要： An insert is configured to be inserted into a heat exchanger having a plurality of tubes. The insert includes a base and a multiple blades. The blades are extended from the base. At least one of the blades has a spring portion. The spring portion is resiliently deformable and configured to be resiliently inserted between two of the tubes. The spring portion includes two arms. One of the two arms has one thin portion defining one recess dented in one direction in a thickness direction. The other of the two arms has the other thin portion defining the other recess dented in the other direction in the thickness direction. The one thin portion and the other thin portion are resiliently movable in a width direction within a clearance formed by the recesses, while overlapping one another in the thickness direction.
