摘要： PROBLEM TO BE SOLVED: To improve the heat exchanger efficiency of a catalytic combustion heater. SOLUTION: The catalytic combustion heater comprises fins 17B in boiling portions 31B for zoning the same into a plurality of small channels arranged perpendicularly to the surface thereof in Fig., which boiling portions are positioned in the midstream of a fluid-to-be-heated channel 3 contacting the intensively heated midstream portion 21B of a combustion gas channel 2 to boil the fluid to be heated. The fins 17B comprise through holes 170B for allowing adjacent small channels to communicate to each other, reducing pressure difference among the small channels to stabilize the surface of fluid and allowing bubbles expanding by bumping to escape to adjacent small channels so as to prevent the wall surfaces of the channels from being covered by gas layers poor in heat transfer efficiency, thereby allowing heat concentrated in the boiling portions 31B to be effectively transferred to the fluid to be heated.

摘要： PROBLEM TO BE SOLVED: To provide an ejector type refrigerating cycle, restraining frost formation of a suction side evaporator connected to a refrigerant suction opening of an ejector. SOLUTION: When an outflow side refrigerant temperature Toe, which is a refrigerant evaporation temperature at an outflow side evaporator 16 which evaporates a refrigerant flowing out from the ejector 15 is lower than a first reference temperature KTH, a throttle passage area of a nozzle part 15a of the ejector 15 is reduced, and also a throttle passage area of an electric expansion valve 17 disposed on the upstream side of a suction side evaporator 18 connected to a refrigerant suction opening 15b of the ejector 15 is enlarged. Thus, a temperature difference between the refrigerant evaporation temperature of the outflow side evaporator 16 and the refrigerant evaporation temperature of the suction side evaporator 18 is reduced to restrain frost formation of the suction side evaporator 18.

摘要： PROBLEM TO BE SOLVED: To heat a hydrocarbon-based fuel, water and air into a gas state without causing ignition and to uniformly mix the fuel with water and air. SOLUTION: A water channel 46, an air channel 56 and a fuel channel 66 are layered in such a way that a fuel gas channel 72 and a neighboring channel of a fluid to be heated form different fluids to constitute a heat exchange part 34. A mixing part 36 is equipped with plural fins so that water in a vapor state is more uniformly mixed with air and the hydrocarbon-based fuel and supplied to a reforming part 80. Since each fluid is individually heated, the hydrocarbon-based fuel can be heated without causing ignition. Since the channels are laminated so as to make the channel of the fluid to be heated form a different fluid, water, air and the hydrocarbon-based fuel can be uniformly heated and more uniformly mixed.

摘要： PROBLEM TO BE SOLVED: To reduce pressure losses and make almost uniform the distributions of the concentration and flow velocity of fuel mixed with air and finally released. SOLUTION: In an evaporated fuel injecting part 103, evaporated fuel 126 is separated into two streams, which reach evaporated fuel supply passages 103a and 103c. The cross-sectional area of a flow passage for air 120 is at its minimum at a mixing part 104. Nozzles 103b and 103d are provided in opposite positions on the interior wall of the mixing part 104. By causing the air 120 to flow at high speed in the mixing part 104, a negative pressure is created, causing the evaporated fuel 126 to be sucked from the nozzles 103b and 103d and injected into the mixing part 104 to cause the two streams to collide against each other. Since the air 120 flows into a portion where the two streams collide, the evaporated fuel 126 is entrained in and mixed with the air 120. The fuel 128 mixed with the air is released through a releasing part 106. The releasing part 106 is shaped to extend radially about the mixing part 104.

摘要： PROBLEM TO BE SOLVED: To provide a technology which restrains the energy efficiency decline of the whole apparatus, when securing enough heat exchanging quantity in the heating section. SOLUTION: The evaporator 10 which vaporizes and heats a reforming fuel uses an anode waste gas emitted from the fuel cell 40 as the fuel for combustion, when combustion reaction for heating. The anode exhaust gas distributes and supplies to the evaporator 10 through 3 ways, which are consisted of No.1 combustion supply route 54 of fuel or No.3 combustion supply route 56 of fuel. The air is supplied from the blower 28 to the evaporator 10 for combustion reaction. By controlling the air quantity based on the temperature when the combustion reaction progresses, the temperature distribution in the evaporator 10 is brought close to a desired state.

摘要： PROBLEM TO BE SOLVED: To provide an evaporator which is high in efficiency, compact and suitable for on-vehicle mounting. SOLUTION: To uniformly mix a fuel atomized from an atomizer 42 and air an air intake piping 46 is installed to be off-centered from 90 degrees toward a center axis of a fuel mixing chamber 44 mixing the fuel atomized from an atomizer 42 and air. A reformed material tank 26 is not only formed as to be thin and wide but also is adopted a structure in which a vapor phase is hard to be produced within by arranging a porous inlet member 28 at a feeding inlet for a heat exchanger 52. A porous outlet member 33 not only homogenizing vapor-liquid phase mixture state of the reformed material in the heat exchanger but also preventing a liquid from jumping out into a raw material mixing tank 32 is arranged under a raw material mixing tank 32. More than one mixing member 34 is arranged in the raw material mixing tank 32 to make a source gas in which a vaporized reformed gas and air are uniformly mixed. An outlet passage of the source gas 38 and the first folding part 51 of fuel gas passage are arranged as to be heat exchangeable to prevent the source gas from cooling.
