The surface has a windward edge and a leeward edge. The plurality of flat tubes include a first flat tube disposed most windward in the second direction, and a second flat tube spaced apart from the first flat tube and disposed most leeward in the second direction. In the second direction, a distance between the leeward edge and a center of a flat shape of the second flat tube is at least one-third of a width between the windward edge and the leeward edge.

A heat exchanger includes a plurality of serpentine or U-shaped first heat transfer tubes disposed in a case and formed by connecting a plurality of straight tube body portions, which are arranged at intervals in an up-down height direction so as to extend in a horizontal direction, in series via a first connecting tube body portion, upper side and lower side header portions connected to respective end portions of the plurality of first heat transfer tubes, and a second heat transfer tube disposed in the case so that upper side and lower side end portions thereof are connected respectively to the upper side and lower side header portions and configured such that an intermediate region, which excludes at least the respective end portions and a region of an uppermost portion that is adjacent to the upper side end portion, is constituted by tube body portions that are tilted over the entire length thereof so as to gradually decrease in height from one end side toward another end side of the intermediate region. As a result, a malfunction in which a hot water supply operation becomes difficult due to freezing of the heat transfer tubes can be prevented appropriately.

A drying apparatus includes a compartment for containing objects to be dried, a closed-loop air pathway and a regeneration heat exchanger. The closed-loop air pathway includes a cooling element and a heating element, and is configured to extract from the compartment air that includes moisture in the form of vapor, to evacuate heat energy from the extracted air to an external fluid flow by cooling using the cooling element so as to remove at least some of the moisture from the air, to reheat the air using the heating element, and to re-introduce the reheated air into the compartment. The regeneration heat exchanger is inserted in the closed-loop air pathway and is configured to transfer heat from the air extracted from the compartment to the air exiting the cooling element in the closed-loop air pathway.

A condensate discharge device of an intercooler for a vehicle is provided to remove condensate collected inside an intercooler. The device includes an ejector hose that is disposed between an inlet tank and an outlet tank to form a flow path for an air flow between the inlet tank and the outlet tank. An ejector housing is disposed on one side of the outlet tank. The condensate collected in the outlet tank is introduced into the ejector housing. An ejector nozzle is disposed in the ejector housing and injects the air introduced from the ejector hose into an inner space of the outlet tank. When injecting the air, to inject the condensate, which is introduced from the outlet tank into the ejector housing, injecting the inner space of the outlet tank with the air.

A heat exchanger, a heat exchanger unit, and a refrigeration cycle apparatus improve a heat exchange performance, a discharge performance, and a frosting resistance, and each include: a flat tube; a fin formed in the shape of a plate having a plate surface extending in a longitudinal direction of the fin that is perpendicular to a width direction thereof, coincides with an up/down direction, and crosses the tube axis of the flat tube; and a first water conveyance member provided below the fin. The first water conveyance member has: a first upper surface facing a lower end portion of the fin; a first ridge located at one end portion of the first upper surface; and a second ridge located at the other end portion of the first upper surface

A modular exhaust configured for exhausting a flue flow of a heat exchanger, the modular exhaust including a cross tube including an inlet end, an exit end and a central axis, wherein the cross tube configured for receiving the flue flow at the inlet end and channeling the flue flow to the exit end; a condensate drainage exit aperture disposed on a bottom portion of the cross tube, the condensate drainage exit aperture configured for draining condensate from the first heat exchanger; and a vertical tube including a central axis, a top end and a bottom end, the cross tube configured to be connected at the exit end of the cross tube to a portion of the vertical tube disposed between the top end and the bottom end, the central axis of the cross tube is not disposed perpendicularly with respect to the central axis of the vertical tube.

A heat exchanger includes: a plurality of flat tubes arranged in a height direction of the heat exchanger; a connection portion in which a plurality of connection spaces are provided as spaces with which ends of the plurality of flat tubes are connected; and a refrigerant distributor connected to each of the plurality of connection spaces. The flat tubes each have a first side end portion located on a windward side, a second side end portion located on a leeward side, and a plurality of refrigerant passages arranged between the first and second side end portions. Each flat tube is inclined such that in the height direction, the position of the first side end portion is lower than the position of the second side end portion. The connection spaces are spaced from each other in the height direction, and a lower side of each of the connection spaces has a first region located on the windward side and a second region located on the leeward side, and is inclined such that in the height direction, the position of the first region is lower than a position of the second region.

A chest insert for a freezer is disclosed. The chest insert is placed inside a freezer and food is placed inside the chest insert. Several sides of the chest insert comprise a gap which is partially filled with a refrigerant gel. These gaps are slanted such that the gel can expand into a wider gap as it expands while freezing, lessening the risk of uneven freezing causing the refrigerant gel to press agains the walls of the chest insert. The use of the disclosed subject matter reduces freezer burn by stabilizing humidity. Further, the chest insert maintains the temperature inside the chest insert for extended periods if the freezer fails or the power to the freezer is interrupted.
