The invention concerns a heat exchanger having an exchange body having first passages for the flow of a first fluid and second passages for the flow of a second fluid exchanging heat with the first fluid, a first inlet manifold for introducing the first fluid into the first passages, a first outlet manifold for discharging the first fluid from the first passages). The heat exchanger also includes an inlet filter arranged facing the inlet surface of the exchange body, and/or an outlet filter arranged facing the outlet surface of the exchange body, the inlet filter and/or the outlet filter having a sheet metallic material selected from a metal gauze, a non-woven fabric of metallic fibres, a sintered metallic powder or sintered metallic fibres.

A fluid flow-path device facilitates a maintenance operation to remove a foreign substance adhered to a member, to prevent passage of the foreign material. The fluid flow-path device has a distribution header including a partition member and a header body in a flow-path formation body. The partition member partitions a distribution space of the distribution header into an upstream-side space that communicates with a supply opening in the header body, and a downstream-side space that communicates with a plurality of flow paths in the flow-path formation body. The partition member includes a region that prevents a foreign substance in a fluid from flowing from the upstream-side space to the downstream-side space, while allowing the fluid to flow. The header body has an opening that allows a washing fluid to flow into the downstream-side space, and an opening that allows the washing fluid to be discharged from the upstream-side space.

A heat exchanger includes: a hollow pillar shaped honeycomb structure; a first cylindrical member fitted to a surface of an outer peripheral wall of the pillar shaped honeycomb structure; a second cylindrical member fitted to a surface of an inner peripheral wall of the pillar shaped honeycomb structure; a cylindrical guide member having a portion, the portion being disposed on a radially inner side of the second cylindrical member with a distance so as to form the flow path for the first fluid; an upstream cylindrical member connecting an upstream end of the first cylindrical member to an upstream side of the guide member; and a downstream cylindrical member connected to a downstream end of the first cylindrical member. The guide member includes an inclined portion that inclines to its downstream side.

A water processor is provided for processing or conditioning water to be distributed downstream of the water processor. The water processor includes a housing having an inlet and an outlet opposite the inlet. The water processor includes a conditioning element disposed inside of the housing between the inlet and outlet. The conditioning element includes a plurality of plates having apertures with sharp edges to direct the flow of water and facilitate splitting of small gas bubbles into even smaller nano-bubbles. The plurality of plates include a first plate having a first configuration of apertures and a second plate having a second configuration of apertures. The first and second plates are disposed in alternating spaced arrangement along the longitudinal axis of the housing. The second configuration is different from the first configuration such that the flow path through the water processor is circuitous or substantially indirect.

An apparatus for storing organic materials includes: a body having an opening for receiving the organic materials to be stored; an outlet formed in the body through which the organic materials are unloaded from the body; and a cooling fluid circuit for circulating cooling fluid through the organic material collected by the hopper.

A circulating water preparation system for cooling plants, a cooling system, in particular a recooling system, and a method for operating such a cooling system. In such a cooling system a surface of a heat exchanger is cooled by wetting with water, the water is collected in a collecting tank and returned by means of a water circuit for the renewed wetting of the surface of the heat exchanger. The method is characterised in that the water is purified by means of a filter, in particular a membrane filter. As a result considerably less biocide is needed to keep the water free of germs, in particular legionella, compared to conventional cooling systems or methods for operating such cooling systems.
