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 |
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 |
20100012310 | SECTIONED FLOW DEVICE - The present invention relates to a sectioned heat exchanger plate, sectioned flow module or sectioned plate reactor, which comprises one or more heat exchanger sections and one or more regulating valves, which regulating valves are connected to the inlet of each heat exchanger section or are connected to the outlet of each heat exchanger section or are connected to the inlet and outlet of each heat exchanger section, each heat exchanger section being at an angle of 90° relative to a main direction of flow for a process flow in at least one flow plate or relative to a main direction of flow for a process flow in said sectioned flow module or relative to a main direction of flow for a process flow in said sectioned plate reactor. The present invention also relates to a method for regulating the temperature in a sectioned heat exchanger plate, flow module or plate reactor. | 01-21-2010 |
