A cover member adapted to cover the heating element and the coiled pipe member includes at least one opening therethrough adapted to allow air to pass through and circulate around the heating element and the coiled pipe member and create a convection effect capable of adding additional heat to the water while passing through the coiled pipe member.

A heat exchanger (1) is provided with header pipes (2, 3), a plurality of flat tubes (4) disposed between the header pipes, and corrugated fins (6) disposed between the flat tubes (4). The end of the corrugated fin at the surface on the side, on which condensed water gathers, of the heat exchanger protrudes from an end of the flat tube (4), and a linear water-conducting member (10) is inserted between a gap (G) formed between the protruding portions of the corrugated fins. The interval between the water-conducting member and the protruding end of the corrugated fin located thereon is a distance at which the surface tension of water can act therebetween. A V-shaped cut (6a or 6b) is formed at the edge of the protruding end of the corrugated fin.

The present disclosure provides, among other things, a radiator system, its components, as well as methods of mounting and/or installing thereof. Provided components include radiating fins arranged around a water pipe to form a core assembly. The radiating fins may include a collar and/or reflare and are spaced in the core assembly to permit airflow through the system. The core assembly may be mounted by support elements on hangers from a back plate which is wall mountable. The support elements may create space for airflow between the core assembly and a front casing and/or the back panel. Provided systems, components and methods are useful in commercial and residential baseboard radiators.

A heat exchanger can include a core, a first tank, and a set of guide members. The core can include a first end member, a second end member, and a plurality of tubes that can extend longitudinally between the first and second end members.

The first tank and first end member can define a first chamber that can be in fluid communication with a first port of the first tank and a first end of the tubes. The set of guide members can be coupled to the first end member. The set of guide members can cooperate to define a plurality of first funnels. A narrow end of each first funnel can be open to an individual one of the tubes. A wide end of each first funnel can be open to the first chamber.

A heat exchanger is provided. The heat exchanger includes a first wall manifold. The heat exchanger further includes a second wall manifold spaced apart from the first wall manifold. The heat exchanger further includes a plurality of vanes that extend generally circumferentially between the first wall manifold and the second wall manifold. The heat exchanger further includes a plurality of fluid circuits defined within the heat exchanger. Each fluid circuit in the plurality of fluid circuits includes an inlet channel portion and an outlet channel portion defined within the first wall manifold. A return channel portion defined within the second wall manifold. At least one passage portion of a plurality of passage portions defined within each vane of the plurality of vanes. The at least one passage portion extends between the return channel portion and one of the inlet channel portion and the outlet channel portion.

A three-way heat exchanger includes panel assemblies arranged in series. Each panel assembly includes a frame defining a heat transfer fluid channel and a vapor-permeable membrane positioned on the frame to define a desiccant channel separated from the heat transfer fluid channel. The three-way heat exchanger also includes clamping assemblies for exerting a clamping force on the panel assemblies. Each clamping assembly includes a tie rod extending through the frames of the panel assemblies and including opposite ends, retainers connected to the opposite ends of the tie rod, and a resilient element positioned between one of the retainers and one of the panel assemblies at one of the ends of the tie rod. The resilient element is deformable to accommodate size variations of the panel assemblies.

A heat exchanger includes a plurality of plate-shaped fins arranged at intervals such that air flows between adjacent fins, each of the fins having insertion holes and a plurality of flat tubes extending through the fins such that a refrigerant flows through the tubes in a stacking direction of the fins, each flat tube having a cross-section having straight long sides and half-round short sides, each flat tube having long-side outer circumferential surface parts and a short-side outer circumferential surface part in contact with the fin and covered with the brazing filler metal. The fins and the flat tubes are joined with the brazing filler metal covering the outer circumferential surfaces of the flat tubes such that top part of each fin collar of each fin is in contact with the flat tube and base part of the fin collar is spaced apart from the flat tube.

The present disclosure provides a motor assembly. The motor assembly includes a motor including a housing, and a heat exchanging apparatus configured on the motor and fluidically coupled to the housing. The heat exchanging apparatus includes a primary compartment adapted to receive a working fluid from the housing, a first compartment adapted to receive a first portion of the working fluid from the primary compartment and transfer the first portion to the housing, and a second compartment adapted to receive a second portion of the working fluid from the primary compartment and transfer the second portion to the housing. The heat exchanging apparatus facilitates exchange of heat between the working fluid and a cooling fluid, such that the first and second portions of the working fluid being transferred to the housing is cooler that the working fluid received by the primary compartment of the heat exchanging apparatus.
