Disclosed are a cooling water-saving device for a cooling tower, and a wet cooling tower. The cooling water-saving device comprises indirect heat exchange devices and a water collecting tank. The inner wall of a cooling tower shell is sealed by the water collecting tank. The indirect heat exchange device comprises a heat exchange channel and a heat insulation channel. The heat insulation channel penetrates through the bottom of the water collecting tank, and the bottom inlet of the heat insulation channel communicates with air entering from the bottom of the cooling tower shell. The heat exchange channel for shielding water drops is arranged at the top outlet of the heat insulation channel, and the top of the heat exchange channel extends into an air outlet in the upper part of the cooling tower shell. The lower outlet of the heat exchange channel communicates with a rain area.

A heat exchanger is provided including a first manifold and a second manifold separated from one another. A plurality of tube segments arranged in a spaced parallel relationship fluidly couple the first and second manifold. The plurality of tube segments includes a bend defining a first slab and a second slab. The second slab is arranged at an angle to the first slab. The heat exchanger has a multi-pass configuration relative to an air flow including at least a first pass and a second pass. The first pass has a first flow orientation and the second pass has a second flow orientation. The second flow orientation is different from the first flow orientation.

A refrigerant diverter diverts inflowing refrigerant and to cause the refrigerant to flow out to a downstream side. The refrigerant diverter includes a vertically extending diverter case, and a vertically extending rod-shaped rod member disposed inside the diverter case. The diverter case has a plurality of diverting channels disposed along a circumferential direction, a diverting space arranged to guide the refrigerant to the diverting channels, and a plurality of expelling spaces that communicate with the diverting space through the diverting channels, the expelling spaces being disposed along a vertical direction. The diverting channels are configured from a plurality of holes extending in a longitudinal direction of the rod member and integrally formed in the rod member.

A heat exchanger includes a plurality of flat tubes, a header part, and a guide part. An interior of the header part is partitioned into first and second spaces. One end of each of the tubes is connected to the first space. The guide part has a guide space positioned below the first space. The guide space communicates with the first space via an ascending opening. The first and second spaces communicate with each other via upper and lower communication ports provided within upper and lower sides of the header part, respectively. When the heat exchanger is viewed from above after installation, the tubes and the ascending opening have an area of overlap, and the ascending opening and a space where the lower communication port is extended do not overlap or have an area of overlap that is up to 50% of the ascending opening.

A chemical reactor including: a plurality of heat exchange plates which between them define reaction compartments, in which reactor each heat exchange plate includes two walls between them defining at least one heat exchange space, the respective walls being fixed together by joining regions, and the reactor also comprises at least one injection device for injecting substance into the reaction compartments, said substance-injection device passing through the heat-exchange plates in respective joining regions thereof. Also, a chemical reaction process that can be carried out in this reactor.

A heat exchanger includes a heat exchange body 2, at least one cover 4 and a manifold 3 connecting the cover 4 to the heat exchange body 2. The heat exchange body 2 is delimited by at least one blanking plate 6. The manifold 3 includes a base plate 20 surrounded by an edge 21 for fixing the cover 4, and the fixing edge 21 is formed by a double-thickness wall 22, one end 23 of which is at least partially fixed to the blanking plate 6.

A heat exchanger module (1) has a supply pipe portion (4) and a return pipe portion (6) that are connected fluidically to a heat exchanger chamber (2) of the heat exchanger module (1). The supply pipe portions (4) of a plurality of heat exchanger modules (1) can be interconnected fluidically to form a supply pipe (24), and the return pipe portions (6) of a plurality of heat exchanger modules (1) can be interconnected fluidically to form a return pipe portion (26). A feed pipe (12) is arranged inside the supply pipe portion (4), and a heat exchange fluid can be fed via the feed pipe (12) to the supply pipe portion (4).

A multi-channel high-efficiency heat dissipation water-cooling radiator includes a water distribution box, a water collection box, a first radiating pipe, a second radiating pipe, a third radiating pipe, and a fourth radiating pipe. Multiple chambers are formed by arranging partitions in both the water distribution box and the water collection box, and each radiating pipe is in communication with the corresponding chambers, so that the channels in the water-cooling radiator are connected in sequence to form a circuitous configuration. This allows the water to travel a longer distance in the water-cooling radiator, so that the water-cooling radiator can effectively cool the water and dissipate heat.

A shell and tube heat exchanger includes a tube bundle for passage of a first medium from a first inlet to a first outlet. A second medium flows through a flow space which surrounds the tube bundle. The tube bundle includes first tubes communicating with the first inlet, and second tubes communicating with the first outlet and fluidly connected to the first tubes. The first tubes define an outer enveloping surface which is predominantly adjacent to an enveloping surface of the second tubes. A separating body between the first inlet and a tubesheet which separates the flow space from the first medium prevents the first medium from flowing against the tubesheet and includes inlet tubes which bridge a compensation space between the separating body and the tubesheet and which protrude into the first tubes to direct the first medium into the first tubes while bypassing the tubesheet.

Disclosed is a shell-and-tube heat exchanger type with a tube bundle and has a redistribution chamber connected to tubes of the tube bundle and to a duct. The duct extends between the redistribution chamber and the shell.
