Abstract
An evaporator (e.g., a small-sized high-efficiency evaporator) and a fuel reformer having the same. The evaporator has multi-stage structure (e.g., a four-stage disk structure), in which the respective disks are filled with fin structures. The first two disks through which exhaust gas passes and the second two disks through which water passes are stacked alternately with each other. Also, the first two disks are coupled with each other by a first pipe penetrating through one of the second two disks, and the second two disks are coupled with each other by a second pipe penetrating through one of the first two disks.
Claims35
An evaporator of a fuel reformer comprising:
- a first stage having a first chamber, a first first opening and a first second opening, the first first opening and the first second opening for allowing the first fluid to enter into and exit from the first chamber;
- a second stage stacked together with the first stage as a stack of the stages, the second stage having a second chamber, a second first opening and a second second opening, the second first opening and the second second opening for allowing the second fluid to enter into and exit from the second chamber;
- a first fin structure in the first chamber and for increasing a heat-exchange surface area with a flow of the first fluid within the first chamber;
- and
- a second fin structure in the second chamber and for increasing a heat-exchange surface area with a flow of the second fluid within the second chamber.
An evaporator of a fuel reformer comprising:
- a first stage having a first inlet for allowing a first fluid to enter into the first stage and a first outlet for allowing the first fluid to exit from the first stage;
- a first fin structure in the first stage;
- a second stage having a second inlet for allowing a second fluid to enter into the second stage and a second outlet for allowing the second fluid to exit from the second stage;
- a second fin structure in the second stage;
- a third stage having a third inlet for allowing the first fluid to enter into the third stage and a third outlet for allowing the first fluid to exit from the third stage, the second stage being between the first stage and the third stage;
- a third fin structure in the third stage;
- a first pipe penetrating through the second stage and for coupling the first stage to the third stage;
- a fourth stage having a fourth inlet for allowing the second fluid to enter into the fourth stage and a fourth outlet for allowing the second fluid to exit from the fourth stage,
- a fourth fin structure in the fourth stage;
- and
- a second pipe penetrating through the third stage and for coupling the second stage to the fourth stage.
27 The evaporator of claim 15, wherein each of the first, second, third and fourth fin structures is metallic.
A fuel reformer comprising:
- a reforming reactor;
- an evaporator for providing a second fluid to the reforming reactor;
- and
- a heat source for providing a first fluid to the evaporator,
- the evaporator comprising:
- a first stage having a first inlet for allowing the first fluid to enter into the first stage and a first outlet for allowing the first fluid to exit from the first stage;
- a first fin structure in the first stage;
- a second stage stacked together with the first stage as a stack of the stages and having a second inlet for allowing the second fluid to enter into the second stage and a second outlet for allowing the second fluid to exit from the second stage;
- and
- a second fin structure in the second stage.
