A plate package for a heat exchanger device includes a plurality of heat exchanger plates of a first type and a plurality of heat exchanger plates of a second type. At least the heat exchanger plates of the first type include, along at least a section of the opposing side portions, a draining channel flange. The draining channel flanges are oriented in one and the same direction such that a draining channel flange of a first heat exchanger plate of the first type abuts or overlaps a draining channel flange of a subsequent heat exchanger plate. The draining channel flanges form outer walls to the outer draining portions thereby transforming the outer draining portions into draining channels. A method of using such plate package in a heat exchanger device and also a heat exchanger device as such are also disclosed.

The plate-type heat exchanger includes blocks stacked on each other, each of the blocks including a heat exchanger body configured to exchange heat between a first fluid and a second fluid. A connection passage for the first fluid is formed between blocks adjacent to each other of the plurality of blocks, the connection passage allowing the outlet of one of the blocks adjacent to each other and the inlet of the other of the blocks adjacent to each other to communicate with each other, the first fluid in the blocks adjacent to each other having different flow directions between the blocks adjacent to each other, and a second connection passage is provided between at least one pair of blocks adjacent to each other among the plurality of blocks, the second connection passage being configured to cause the first fluid to flow to a position different from the connection passage.

Disclosed is a shell-and-tube heat exchanger type with a tube bundle and has a redistribution chamber connected to tubes of the tube bundle and to a duct. The duct extends between the redistribution chamber and the shell.

A heat exchanger is formed by stacking plates with each other. The heat exchanger includes a refrigerant receiving tank configured to receive a refrigerant, a refrigerant discharging tank configured to discharge the refrigerant that has heat-exchanged, and refrigerant passages in which heat exchange between the refrigerant and another fluid is performed. The refrigerant passages fluidly connect between the refrigerant receiving tank and the refrigerant discharging tank. The refrigerant receiving tank includes a swirl structure configured to generate a swirling component in a flow of the refrigerant in the refrigerant receiving tank.

A total heat exchange element includes a plurality of partition members made of a material that contains cellulose as a main component, a spacing member made of a material that contains cellulose as a main component, and an adhesive portion bonding the partition members and the spacing member together. The partition members are configured as flat sheets, and are stacked with a predetermined distance between them. The spacing member is disposed between adjacent ones of the stacked partition members to maintain the distance between them. The total heat exchange element has a first air flow path and a second air flow path alternately formed with one of the partition members interposed between the first and second air flow paths. The adhesive portion contains, as an adhesive component, cellulose having a smaller diameter than both of the cellulose forming the partition members and the cellulose forming the spacing member.

A core body includes a structure having a plurality of connected unit cells. At least one unit cell has one or more sidewalls that are curved and define a portion of an inner passageway within and through the unit cell. The one or more sidewalls define multiple orifices and include a cone disposed between at least some of the orifices. A dimple is defined along an outer surface of the unit cell at the cone. The outer surface at least partially defines an outer passageway that is sealed from the inner passageway by the one or more sidewalls. The one or more sidewalls are configured to transport one or more of thermal energy from a first fluid or a component of the first fluid flowing in the inner passageway to a second fluid flowing in the outer passageway without the first fluid mixing with the second fluid.
