The filter cartridge for the water tank of a coffee machine comprises a housing having on both sides a plurality of slot-shaped openings constituting two inlets. For softening the water, the housing of the filter cartridge contains a ion exchange resin. The bottom of the housing comprises a central outlet. The interior of the housing is provided with a plurality of baffle members increasing the length of the flow path of the water between inlets and outlet. The housing comprises an upper portion and a lower portion, sealingly fixed to each other. The baffle members extend essentially in vertical direction and are alternately fixed to the upper and to the lower housing portion. Water passages are provided between the upper housing portion and the baffle members fixed to the lower housing portion, as well as between the lower housing portion and the baffle members fixed to the upper housing portion. The filter cartridge of the invention requires not much space, but offers high efficiency resulting from the long flowing path of the water through the ion exchange resin between inlets and outlet.

A helical heat exchanger assembly comprises a plurality of helical heat exchangers, each helical heat exchanger comprising a tube having first and second ends, a length, an inner diameter and a cross-section incorporating the inner diameter, a thermally conductive tube insert having a length and an outer diameter substantially equal to the inner diameter of the tube, the tube insert having first and second ends and comprising a single helix extending along the length of the tube insert and twisted around a central axis. The tube insert is sealed within the tube by sealing an outer edge of the helix to an inner surface of the tube to form fluid-tight first and second fluid flow paths defined between opposing sides of the helix and the inner surface of the tube, respectively. A plurality of inlet and outlet fluid ports are positioned for passage of a first and second fluid into and out of each tube. A first manifold connects each of the first ends of the heat exchanger tubes and a second manifold connects each of the second ends of the heat exchanger tubes, wherein at least one of the first or second manifolds includes baffles to direct fluid flow within the manifold such that at least some of the helical heat exchangers may be arranged in series, or in parallel, within the heat exchanger assembly via the baffles. Each helix has a predetermined pitch which may be less than or greater than the tube inner diameter and defines a length of the first and second fluid flow paths within each heat exchanger tube, wherein the pitch of the helix may be constant or variable along the length of the tube insert.

The present invention discloses a heat dissipation and cooling method for high-heat density cabinets in a data center. According to the method, a large-temperature difference air conditioner end device used for cabinet cooling and cooled cabinets are encapsulated in a constructed object isolated from a machine room environment, so that heat transfer between the inner space of the building and the external machine room environment can be prevented; the large-temperature difference air conditioner end device used for cabinet cooling is arranged at one side of the cooled cabinets, or the large-temperature difference air conditioner end device is arranged between the two cooled cabinets; the large-temperature difference air conditioner end device for cabinet cooling and the cooled cabinets are connected with a control system; and the large-temperature difference air conditioner end device for cabinet cooling can realize automatic adjustment according to the control system. According to the heat dissipation and cooling method for the high-heat density cabinets in the data center of the invention, the inner surface area of a circulating liquid flowing pipeline is increased, so that the heat exchange area of single heat exchangers can be increased; and the heat exchangers are connected in series with one another, so that the length of the flowing path of a circulating liquid can be obviously increased, and a small-flow rate and inlet / outlet large-temperature difference operation mode of the circulating liquid can be realized.

A semiconductor structure and a method for forming a semiconductor structure are disclosed. A forming method may include: providing a base, including a first region used to form a well region and a second region used to form a drift region, where the first region is adjacent to the second region; and patterning the base, to form a substrate and fins protruding out of the substrate, where the fins include first fins located at a junction of the first region and the second region and second fins located on the second region, where the quantity of the second fins is greater than the quantity of the first fins. In some implementations of the present disclosure, the quantity of the second fins is increased to correspondingly increase the length of a flow path in which a current flows from a drain region to a source region, thereby reducing a voltage drop in the current flow path, and further improving a breakdown voltage of an LDMOS, to improve the device performance of the LDMOS.
