20120325444 | SPIRAL HEAT EXCHANGER - A spiral heat exchanger includes a spiral body formed by at least one spiral sheet wound to form the spiral body forming at least a first spiral-shaped flow channel for a first medium and a second spiral-shaped flow channel for a second medium, wherein the spiral body is enclosed by a substantially cylindrical shell being provided with connecting elements communicating with the first flow channel and the second flow channel, where the at least one spiral sheet comprises a corrugated heat transfer surface with corrugations for increasing the heat transfer and supports for spacing the wounds of the at least one spiral sheet in the spiral body. | 12-27-2012 |
20130020062 | PLATE HEAT EXCHANGER AND METHOD OF PRODUCING A PLATE HEAT EXCHANGER - A plate heat exchanger comprises a stack of heat transfer plates each extending in a general plane and provided with a main heat transfer portion with a corrugation pattern. Each heat transfer plate comprises an outer peripheral portion extending outside the main heat transfer portion and along a periphery. The outer peripheral portion comprises outer and inner edge portions. In the stack the heat transfer plates in their outer peripheral portions abut against each other alternately along the outer and inner edge portions, and are welded together alternately along the outer and inner edge portions. The heat transfer plates in the stack are welded together by melting material of the heat transfer plates closest to abutting faces of the edge portions by supplying welding energy in a direction substantially parallel to the general plane to produce weld joints between the heat transfer plates in the outer and inner edge portions. | 01-24-2013 |
20130299146 | PLATE HEAT EXCHANGER - A stack of heat transfer plates configured to be arranged within a block-type heat exchanger. The stack of heat transfer plates comprises pairs of heat transfer plates that are stacked such that a flow path for a first fluid is formed between the stacked pairs of heat transfer plates, wherein a pair of the stacked pairs of heat transfer plates comprises a first heat transfer plate and a second heat transfer plate that are joined such that a flow path for a second fluid is formed between the first and second heat transfer plates. The pair of heat transfer plates comprises corrugations that are arranged on a respective side of an elongated joint that joins the first and second heat transfer plates. A related plate heat exchanger is also disclosed. | 11-14-2013 |
20140131020 | MODULE OF HEAT TRANSFER PLATES AND PLATE HEAT EXCHANGER COMPRISING SUCH MODULE - A module of heat transfer plates which are welded to each other comprises a first outer heat transfer plate, at least a first and a second heat transfer plate, and a first reinforcement arrangement. Port holes form a first port channel in the module. The first reinforcement arrangement comprises a first abutment member and a first supporting member. The first abutment member is arranged on a side of the first outer heat transfer plate opposite to the first heat transfer plate. The first supporting member is arranged between the first abutment member and the first outer heat transfer plate. The first supporting member abuts against the first abutment member and the first outer heat transfer plate. Further a heat exchanger comprising such a module is provided. | 05-15-2014 |
20140131025 | HEAT TRANSFER PLATE FOR A PLATE-AND-SHELL HEAT EXCHANGER - A heat transfer plate configured to be arranged in a plate-and-shell type plate heat exchanger. The heat transfer plate comprises an inlet port and an outlet port. The inlet port has a first inlet section that faces the outlet port and comprises a first fluid blocker, for distribution of at least a part of a flow of fluid over a second inlet section of the inlet port. The outlet port has a first outlet section that faces the inlet port and comprises a second fluid blocker, for distribution of at least a part of the flow of fluid over a second outlet section of the outlet port. Corrugations are arranged intermediate the inlet port and the outlet port. | 05-15-2014 |
20140251550 | PLATE EVAPORATOR OF THE FALLING FILM TYPE, AND A PLATE EVAPORATOR APPARATUS HAVING SUCH A PLATE EVAPORATOR ARRANGED IN A HOUSING - A plate evaporator apparatus of the falling film type comprises a housing having an inlet for liquid to be evaporated and having mounted therein a package of heat transferring plates with plate interspaces, every second one of which forms an evaporation space for at least partial evaporation of liquid and the other plate interspaces forming condensation spaces for at least partial condensation of a heat emitting vapour. First seals delimit distribution chambers, each of which is in liquid flow communication with at least one evaporation space by flow ways spaced apart along the package width. The heat transferring plates have through openings aligned to form a passage extending through the plate package. A pipe is connected to the inlet and has apertures distributed along its length in flow communication with the distribution chambers, for supplying the liquid to be evaporated from the inlet to the distribution chambers through the apertures. | 09-11-2014 |
