The mold comprises: a first mold, the first mold forming holes (110) in the multiple heat exchange tubes (11); and a second mold (2), the second mold having a mold cavity (20) forming a main body of the heat exchange assembly (1), the mold cavity (20) having an opening (21), the heat exchange assembly (1) being extruded from the opening (21) of the mold cavity (20) of the second mold (2), and the opening (21) being strip-shaped and extending along a curved line.

A cooling device for reducing the temperature of cooked warm food in a liquid or paste-like state held in a container, in particular in a standard trolley, is provided. The cooling device includes a plate-like covering member which covers the opening cross-section of the container or of the standard trolley, wherein the covering member has vertically arranged cooling elements on the lower face thereof, which cooling elements, when the cooling device is attached and lowered, are immersed in the density of the food and a cooling medium circulates through the cooling elements, which cooling medium extracts the stored heat from the food. A stripping plate designed as a perforated sheet or as a perforated plate is provided on the lower face of the covering member, which stripping plate removes remaining food from the cooling elements during withdrawal of the cooling device.

Embodiments of the present disclosure are directed to a climate management system that includes a heat exchanger having a first set of microchannel coils fluidly coupled to a first circuit of the climate management system and a second set of microchannel coils fluidly coupled to a second circuit of the climate management system, where the first circuit and the second circuit are fluidly separate from one another, and where the first set of microchannel coils and the second set of microchannel coils are disposed in an alternating arrangement along a length of the heat exchanger such that the first set of microchannel coils and the second set of microchannel coils are interlaced in the heat exchanger.

An apparatus for the maintenance and operation of an air-cooled heat exchanger (ACHE) includes a plurality of spray tubes provided with spaced-apart nozzles permanently positioned between the finned heat exchange tubes and longitudinally aligned within the region of the finned-tube pitch. The apparatus is operable in several modes, including cleaning where the flow of air is stopped and temperature-controlled pressurized water with an optional cleaning agent is discharged from the nozzles to dislodge dirt and debris from the finned surfaces while simultaneously cooling the hot process liquid. When extremes of ambient air temperatures preclude the forced air fans from achieving the target temperature range of the process liquid passing through the ACHE, refrigerated pressurized cooled water and compressed air in the form of a mist is discharged from the nozzles, or alternatively, pressurized heated air is discharged from the nozzles.

Cooling unit in which the first and second heat exchangers [13], [16] are suspended along one of their longitudinal edges respectively to one of the suspension pipes selected from first, second and third pipes, [10], [11], [12], and are capable of undergoing a substantially free elongation and/or expansion curvature below the level of the pipe suspension.

A heat exchanger includes a casing configured to direct a working fluid therethrough, and at least one heat exchanger (HE) section in the casing. Each HE section includes a pair of spaced supports. The spaced supports include: an upstream support and a downstream support with at least one of them including a coolant carrying body configured to direct a coolant therethrough. A first cross-support couples to and extends between respective upstream and downstream supports; and at least one second cross-support couples to and extends between the respective upstream and downstream supports. Cross-supports are vertically distanced from adjacent cross-supports. A plurality of tube positioners coupled to each cross-support position a plurality of heat exchange tubes extending across a working fluid path through the casing. The tube positioners and the cooling of the cross-supports allows ferritic material to be used for once-through, duct-fired HRSGs.

A high-temperature flow-splitting component, applicable to a temperature range from a first temperature to a second temperature, includes an entrance channel, at least one primary channel and at least one subordinate channel. The entrance channel is used for introducing a fluid at a total flow rate. The at least one primary channel for introducing the fluid from the entrance channel at a first flow rate is connected with the entrance channel by a first angle ranging from 90°˜270°. The at least one subordinate channel for introducing the fluid from the entrance channel at a second flow rate is connected with the at least one primary channel by a second angle ranging from 30°˜150°. A sum of the first flow rate and the second flow rate is equal to the total flow rate.
