Disclosed is an evaporator for an ice maker including: a refrigerant pipe having a circular cross-section, with refrigerant flowing therethrough; and a pair of ice making plates disposed on opposite sides of the refrigerant pipe. The refrigerant pipe is disposed between inner side surfaces of the ice making plates facing each other, and rounded parts are provided by being formed outwards at a place where the refrigerant pipe is located such that the rounded parts cover both sides of the refrigerant pipe by being in close contact therewith.

An improved indirect heat exchanger is provided which is comprised of a plurality of coil circuits, with each coil circuit comprised of an indirect heat exchange section tube run or plate. Each tube run or plate has at least one change in its geometric shape or may have a progressive change in its geometric shape proceeding from the inlet to the outlet of the circuit. The change in geometric shape along the circuit length allows simultaneously balancing of the external airflow, internal heat transfer coefficients, internal fluid side pressure drop, cross sectional area and heat transfer surface area to optimize heat transfer.

A container for warming fluids, the container comprising an inlet port, an outlet port, and a fluid conduit configured for putting the inlet port in fluid communication with the outlet port and comprising one or more deflection sections. The fluid conduit has a non-constant maximum width in a direction of fluid flow through the fluid conduit. At least one of the one or more deflection sections further comprises an entry section and an exit section, each respective exit section being arranged downstream, in the direction of fluid flow, from each respective entry section. The maximum width of the fluid conduit decreases along the direction of fluid flow through the entry section over a first distance and the maximum width of the fluid conduit increases along the direction of fluid flow through the exit section over a second distance, the first distance and the second distance being different from one another. An apparatus for warming medical fluids including the container and an extracorporeal blood circuit including the container are also provided. An extracorporeal blood treatment apparatus including the apparatus for warming medical fluids and/or the extracorporeal blood circuit is also provided.

A cooling apparatus includes a plurality of containers and a plurality of connectors. Each connector connects adjacent containers of the plurality of containers. The cooling apparatus is installable in a computing device such that each electronic component to be cooled in the computing device is interposed between adjacent containers. Each container may include a body, an inlet, and an outlet. The body may include first and second ends and may define a chamber through which a coolant is to flow. The body may be expandable responsive to pressure from the coolant and deformable responsive to contacting one of the electronic components so as to conform to a profile of the electronic component. The inlet may be disposed at the first end of the body through which the coolant enters the chamber. The outlet may be disposed at the second end of the body through which the coolant exits the chamber.

An air-over evaporative heat exchanger with multi-lobed or peanut shaped tubes replacing conventional round or elliptical tubes. The tubes have a narrow horizontal cross section and tall vertical cross section to allow the multiplication of surface area in the same coil volume while maintaining or increasing the open-air passage area. This configuration allows the coil to have an overall external heat transfer coefficient much higher than a conventional coil, while the tube shape allows the use of thinner material, reducing the weight and cost of the heat exchanger.

A liquid to refrigerant heat exchanger includes an enclosed coolant volume that is at least partially defined by a plastic housing and by a metal closure plate. The metal closure plate can be part of a brazed assembly containing a continuous refrigerant flow path. The refrigerant flow path is disposed within the coolant volume, where heat can be transferred between the refrigerant within the refrigerant flow path and the liquid within the coolant volume. The plastic housing can at least partially surround the refrigerant flow path to at least partially bound a liquid flow path along a portion of the coolant volume. An inlet diffuser and an outlet diffuser can be mounted to the housing to direct the liquid through the housing. The plastic housing is sealingly joined to the closure plate along an outer periphery of the closure plate.

A heat exchanger includes a case body and a heat exchange core, a first fluid channel is formed in the case body, a second fluid channel is formed in the heat exchange core, the heat exchange core includes a flat pipe, the second fluid channel is located in the flat pipe, the flat pipe includes a plurality of bending parts and a plurality of flat and straight parts; a first hole in communication with a first connection pipe and a second hole in communication with a second connection pipe are provided in the case body, the first hole partially corresponds to the bending parts on one side of the flat pipe or the flat and straight parts close to the bending parts, and the second hole partially corresponds to the bending parts on the other side or the flat and straight parts close to the bending parts.

A heat exchanger includes: a first heat transfer portion including a plurality of first flat tubes arranged at equal intervals and spaced apart from each other by a distance Dp in a gravity direction; and a second heat transfer portion positioned downstream of the first heat transfer portion in a flow direction of a heat exchange medium perpendicular to the gravity direction, the second heat transfer portion including a plurality of second flat tubes arranged at equal intervals and spaced apart from each other by the distance Dp in the gravity direction.
