A hot water storage device having a vessel includes a first section formed from a moulded material and a second section formed from a moulded material. An open end of the first section is sealingly engaged with an opposing open end of the second section to form the vessel. The first and second sections each have a generally cylindrical body portion and a closed end, comprising a head portion. The vessel includes a water inlet aperture moulded into the first or second section and a water outlet aperture moulded into the first or second section and wherein the inlet and outlet apertures are located on the body portion proximal to a tangent line between the body portion and the head portion.

The present invention relates generally to a manifold for a parallel flow heat exchanger and a heat exchanger incorporating that manifold. The manifold comprising a first plurality of channels each having a first opening facing a first direction and a second opening facing a second direction different from the first direction. The manifold further comprises a second plurality of channels interleaved with the first plurality of channels, the second plurality of channels having a third opening facing a third direction and a fourth opening facing the first direction, wherein the third direction is different from the first direction and the second direction.

The fluid connector assembly includes a connector body with an intermediate portion that extends between opposite end portions and has a first bore. The connector body has an elongated wall that projects outwardly from the intermediate portion and that surrounds a second bore which opens to the first bore. A flat tube, which is made of a second material that is different than the first material and has at least one fluid passage, is in fluid communication with the second bore of the connector body. The flat tube has generally flat side walls and is lockingly retained with the connector body by male and female locking structures that cooperate with one another.

This invention relates to gaskets, apparatus incorporating said gaskets and to methods of using them. In particular, there is provided a gasket comprising a closed loop of resilient material, the loop having an inner periphery and an outer periphery, the gasket having a first thickness at a first position which is between 0% and 30% of the gasket width away from the outer periphery, a second thickness at a second position measured at a point at least 50% of the gasket width from the first position, and a third thickness at a third position intermediate the first and second positions and at least 10% of the gasket width from each, the first thickness being greater than the third thickness which is greater than the second thickness, and wherein either a said gasket reduces in thickness from the first thickness to the third thickness and then to the second thickness via one or more tapered sections which taper linearly to a reduced thickness in the direction towards the inner periphery, or b said gasket reduces in thickness from the first thickness to the third thickness via one or more steps which step to a reduced thickness in the direction towards the inner periphery and then from the third thickness to the second thickness via one or more steps which step to a reduced thickness in the direction towards the inner periphery, or c said gasket reduces in thickness from the first thickness to the third thickness and then to the second thickness via a combination of one or more steps and one or more tapered sections as defined above.

Disclosed herein is a gas-liquid mixing and distributing device. The gas-liquid mixing and distributing device includes a mixing head including a chamber, a plurality of gas spray nozzles, and a plurality of liquid spray nozzles; and a liquid supplying part connected to the mixing head and supplying a liquid to the mixing head, wherein the plurality of gas spray nozzles and the plurality of liquid spray nozzles included in the mixing head are uniformly mixed and distributed so that the liquid and gas sprayed from the mixing head are uniformly mixed with each other.

The present disclosure relates to a heat exchanger including a plurality of fluid guiding metal pipes (2) having pipe ends (3) arranged side by side at intervals, at least one pipe bottom (4) made of plastic and having receiving through-holes (5) in which the pipe ends (3) may be received, and a collection box (6) made of plastic and which may be connected to the pipe bottom (4) by a locking device formed between the pipe bottom and the collection box, wherein a seal (9) may be inserted between the pipe bottom (4) and the collection box (6), and the seal ensures press-fit of the pipe bottom (4) on the pipe ends (3) and seals the collection box (6) against the pipe bottom (4) and the pipe bottom (4) against the pipe ends (3).

An arc-shaped plate heat exchanger, including a cylindrical housing and a heat-exchanging plate assembly. The heat-exchanging plate assembly includes two groups of arc-shaped heat-exchanging plates symmetrically disposed at either side of the axis of the housing. In each group of the arc-shaped heat-exchanging plate, multiple arc-shaped heat-exchanging plates are arranged from the housing center outward and form isolating first and second fluid channels, the plates' diameters increasing outward. During heat exchange, cold fluid enters the heat exchanger from the housing's first fluid inlet, and flows through straight channels of the arc-shaped heat-exchanging plates to exit from a first fluid outlet, while the hot fluid enters the heat exchanger from a second fluid entrance on the side wall of the housing, and flows through arc-shaped channels of the arc-shaped heat-exchanging plates to exit from a second fluid outlet. Heat exchange between the cold and hot fluid is thus achieved.

The invention relates to a sealing device (3) for a motor vehicle heat ex-changer (4) consisting of a plate (5) comprising a central cavity (12) configured to allow the passage of a tube of the heat exchanger, characterised in that at least two opposite end edges of said plate (5) are each provided with snap-fastening means (8), each capable of engaging with complementary snap-fastening elements integrated into a recess located in a support frame of the heat exchanger, and characterised in that the sealing device (3) comprises an elastically deformable sealing means (14) arranged around the central cavity (12) formed in the plate (5).

A receiver includes a large diameter main body portion, and an intermediate member side small diameter portion. A wall thickness of the intermediate member side small diameter portion is smaller than a wall thickness of the main body portion. As a result, heat capacity of the intermediate member side small diameter portion is reduced. As a result, it is possible to complete brazing between the intermediate member side small diameter portion and the intermediate member, at the same time as brazing among tanks, tubes, and fins. A desiccant enclosed in a flexible bag can be taken in and out through the intermediate member side small diameter portion.

A geothermal heating and cooling system that uses a water source to provide a heat transfer medium is provided. Elements of the system may include a water source, one or more circulation loops coupled to the water source, a heat exchanger and/or heat pump, and/or a monitoring component configured to monitor for conditions within the system, including leak integrity and water quality.
