A heat exchanger assembly includes a plurality of flattened heat exchanger tubes. The plurality of heat exchanger tubes include a bend that separates the plurality of heat exchanger tubes between extending in a first plane and extending in a second plane transverse to the first plane. An inlet manifold is in fluid communication with the plurality of heat exchanger tubes and includes a distribution insert at least partially extending through an inlet opening in the inlet manifold. An outlet manifold is in fluid communication with the plurality of heat exchanger tubes and includes an outlet opening spaced inward from opposing ends of the outlet manifold.

A shell-and-plate heat exchanger includes: a shell forming an internal space; and a plate stack, disposed in the internal space, including heat transfer plates that are stacked and joined together. The shell-and-plate heat exchanger is configured to allow a refrigerant that has flowed into the internal space to evaporate. The plate stack forms: refrigerant channels that communicate with the internal space and through which a refrigerant flows; and heating medium channels that are blocked from the internal space and through which a heating medium flows. Each of the refrigerant channels is adjacent to an associated one of the heating medium channels with one of the heat transfer plates interposed therebetween. The shell-and-plate heat exchanger further includes one or more supply structures that supply the refrigerant to the refrigerant channels such that the refrigerant flows downward.

A heat exchanger includes a collecting pipe, a number of heat exchange tubes and a distributor. The collecting pipe has a first cavity and a first inner peripheral wall. The heat exchange tube has a second cavity. The distributor is accommodated in the first cavity. The distributor has a main cavity and a flow channel. The distributor includes a second inner peripheral wall forming the main cavity and a first outer peripheral wall. An axis of the first outer circle is not coaxial with an axis of the second outer circle, so that the flow channel of the distributor is relatively tortuous. It is beneficial to improve the distribution effect of a fluid. Besides, since the flow channel is formed inside the distributor, it is also beneficial to reduce the manufacturing difficulty of the distributor. A method for making the heat exchanger is also disclosed.

A heat exchanger includes a tubular refrigerant distributor having insertion holes spaced from each other in a first direction and into which ends of heat transfer tubes are inserted in a second direction. A first partition plate partitions the refrigerant distributor into a first space into which the ends of the heat transfer tubes are inserted and a second space, larger than the first space, into which the ends of the heat transfer tubes are not inserted; and an inflow pipe provided on a one side-surface side of the refrigerant distributor. The heat transfer tubes are located apart from the first partition plate in the first space. The first partition plate is provided with an orifice that is provided at a location corresponding to a space between adjacent ones of the heat transfer tubes, and that causes the first space and the second space to communicate with each other.

A heat exchanger is provided according to the present application, which includes a core body. The core body includes a first sheet and a second sheet that are arranged in a stacked manner. The core body is provided with a first fluid channel and a second fluid channel that are isolated from one another. The first fluid channel includes a first pore channel and a second pore channel. The core body further includes a first blocking part. The first pore channel includes a first sub-pore channel and a second sub-pore channel. The heat exchanger further includes a first connection port and a second connection port that are located on the same side of the core body in the thickness direction thereof.

A refrigerant distributor includes an outer pipe, an inner pipe, and a structural part. The refrigerant outflow hole is provided such that an angle θ between a lower end of the inner pipe on a vertical line passing through a center of the inner pipe and a position of presence of the refrigerant outflow hole as seen from the center of the inner pipe falls within a range of 10 degrees≤θ≤80 degrees. The refrigerant outflow hole comprises a sole refrigerant outflow hole provided in a vertical cross-section of the inner pipe at a position where the refrigerant outflow hole is provided.

A fluid manifold includes an inlet comprising an opening into an interior of the fluid manifold, an outlet end that is positioned opposite the inlet and that is in fluid communication with the inlet, a shroud extending between the inlet and the outlet end and surrounding a flow path of the fluid manifold, and a first flow distributor positioned within the interior of the fluid manifold. The first flow distributor includes a hollow body including a first surface at a downstream side of the first flow distributor and a second surface at an upstream side of the first flow distributor, a central cavity defined by the second surface of the hollow body, and openings extending from the first surface to the second surface such that a fluid can pass from the central cavity through the openings. The first flow distributor and the fluid manifold are integrally formed.

A spacer device for incorporation into a bent-tube heat exchanger that includes a spine and a plurality of fingers that protrude from one side of the spine. The number of fingers in the spacer device is less than the number of tubes that are folded in a region to form the bent-tube heat exchanger. The plurality of fingers are configured to exert a force against the tubes and to provide and maintain a separation between the tubes in the folded region. A heat exchanger that includes the spacer device may also include a coating on the tubes in the folded region in order to reduce corrosion and increase the life-time of the heat exchanger. The method of forming the heat exchanger includes placing the spacer device between the tubes, such that the fingers lay on the tubes in the region to be folded and assist in the folding process.

Disclosed are a cold-water generating tank for generating cold water by using the ice thermal storage method and a water cooler equipped with same. The disclosed cold-water generating tank may comprise: a tank body which houses, on the inside thereof, an ice storage liquid cooled by means of a cooling unit; a cooling tube provided on the inside of the tank body in order to cool the ice storage liquid housed inside the tank body; and a cold-water generating unit which has a heat exchange tube forming a flow pathway where inflowing water becomes cold water through heat exchange with the ice storage liquid, and has an extension member positioned on the outer circumferential surface of the heat exchange tube in order to widen the area of contact with the ice storage liquid.

A heat exchanger includes a casing having a first inlet, a first outlet, a second inlet, and a second outlet, and a plate assembly positioned between the first inlet and the first outlet and between the second inlet and the second outlet and at least partially in the casing, the plate assembly is being configured to transfer heat between a first fluid and a second fluid. The heat exchanger also includes a first plenum connecting a first side of the plate assembly and configured to direct the first fluid from first inlet to the plate assembly, and a second plenum connecting a second side of the plate assembly and configured to direct the first fluid from the plate assembly to the first outlet.
