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.

A chemical delivery system is provided. The chemical delivery system includes a strand of material having a plurality of chemical delivery tablets secured thereto. The strand of material can be inserted into a drain pipe opening and retained within the drain pipe by a retention disc and/or a removable cap. The chemical delivery tablets are measurably consumed as fluid or other condensate material flows through the drain pipe. The strand of material may then be readily replaced with a new strand on a period basis without necessitating disassembly of the pipe thereby preventing growth of algae or other organic material in the drain pipe.

A dehumidification device with enhanced dehumidification effect includes a gas cooler receiving a first air gas and condensing the first air gas into a first condensing gas and a first condensing liquid. A heat exchanger has an inlet and an outlet. The first condensing gas flows from the gas cooler to a periphery of the heat exchanger to cool the heat exchanger. The inlet receives a second air gas from outside. The second air gas is condensed into a second condensing gas and a second condensing liquid using the cooled heat exchanger, and the second condensing gas and the second condensing liquid are expelled from the outlet. A gas heater receives the first condensing gas flowing through the periphery of the heat exchanger and the second condensing gas expelled from the outlet, and heats and turns them into dry air, and the gas heater expels the dry air.

A heat exchanger may include a first collecting tank and a second collecting tank. The first collecting tank may include a first collecting pipe having a first collecting pipe opening for letting in a fluid and a second collecting pipe having a second collecting pipe opening for discharging the fluid. The second collecting tank may be arranged opposite the first collecting tank and may include a third collecting pipe and a fourth collecting pipe. The heat exchanger may also include a plurality of heat exchanger pipes fluidically connecting the first collecting pipe to the third collecting pipe and the second collecting pipe to the fourth collecting pipe. The heat exchanger may also include a separating wall arranged in each of the first collecting pipe and the second collecting pipe respectively dividing each into a first pipe section and a second pipe section.

Disclosed is a receptor for receiving condensate from a v-coil heat exchanger (v-coil), the receptor having: a first channel having a first length defined between first opposing ends, the first channel configured to receive the v-coil; a second channel having a second length defined between second opposing ends, the second channel including: a first orifice intermediate the second opposing ends for receiving condensate from the first channel, the first orifice being fluidly connected to one end of the first opposing ends at a junction; and a fluid drain port at one or both of the second opposing ends.

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 multiple tube bank heat exchanger includes a first tube bank including at least a first and a second flattened tube segments extending longitudinally in spaced parallel relationship and a second tube bank including at least a first and a second flattened tube segments extending longitudinally in spaced parallel relationship. The second tube bank is disposed behind the first tube bank with a leading edge of the second tube bank spaced from a trailing edge of the first tube bank. A continuous folded fin extends between the first and second flattened tube segments of both of said first tube bank and said second tube bank.

An outdoor unit for an air-conditioning apparatus that includes a bottom plate made of metal, an L-shaped heat exchanger made of metal different than the metal of the bottom plate, a placement plate provided on the bottom plate and having a heat exchanger placement surface on which the heat exchanger is placed. The placement plate having an L-shape in plan view, and the placement plate is held in contact with the bottom plate only below each of a short-side end portion of the placement plate, a long-side end portion of the placement plate, and a corner portion of the placement plate.

A heat exchanger for a fuel cell system, in particular in a vehicle, includes a gas section for at least one gas and one cooling fluid section for cooling the at least one gas, a housing, and a cooler matrix which is arranged in the housing and in which the cooling fluid section is configured, where the cooler matrix forms a multiplicity of cavities which produce the gas section, at least one gas inlet on the housing, at least one partition in the cooler matrix for dividing the gas section into at least two flows, with the result that the two flows can be cooled by way of the same cooling fluid section, and at least two gas outlets on the housing, where each flow opens into a dedicated gas outlet.

A condensation management apparatus comprises a first microstructured film arranged to condense water vapor on a substantially vertical surface of a component. The first film comprises channels disposed on first and second major surfaces of the first film and dimensioned to support capillary movement of condensate. The channels have a channel axis substantially parallel with a longitudinal axis of the first film. The longitudinal axis of the first film is tilted at a tilt angle of at least 4 degrees with respect to an axis normal to a direction of gravity. Openings in the channels are disposed at one or both end edges of the first film. The openings provide condensate release locations of the first film. A second film is disposed over a portion of the first film. The second film attaches the first film to the substantially vertical surface of the component.
