Abstract: A second fluid having a higher temperature than a first fluid, which flows in a duct, flows in contact with outside fins. Opposed regions of each power generation module and the duct apply pressure to and in contact with each other. Opposed regions of each power generation module and a corresponding one of a first outside plate and a second outside plate apply pressure to and in contact with each other. The duct is formed from a material having a thermal expansion coefficient larger than the first outside plate and the second outside plate. Additionally, two power generation modules are not necessarily required, and at least one power generation module is provided.

Abstract: An adsorption core has (i) a heat medium tube in which a heat medium flows and (ii) an adsorption agent that adsorbs a fluid in a vapor phase outside of the heat medium tube when being cooled by the heat medium and desorbs the absorbed fluid when being heated. The heat medium tube has (i) a core member that is made of metal having a higher hardness with respect to copper and (ii) a covering layer that is made of copper and covers an outer surface of the core member. A sintered body of a copper powder and the adsorption agent is provided in a peripheral portion of the heat medium tube. The copper powder and the heat medium tube are metallically coupled with each other. Accordingly, stiffness of the heat medium tube can be higher while improving a heat transfer performance between the heat medium tube and the adsorption agent.

Abstract: An adsorber includes: a closed container in which an adsorption medium is included; an adsorption part that is provided in the closed container and includes an adsorbent, which adsorbs and desorbs the adsorption medium; and an evaporation/condensation part that is provided in the closed container and that exchanges heat between the adsorption medium and a heat exchanging medium, which is supplied from outside of the closed container, to evaporate and condense the adsorption medium. The evaporation/condensation part includes a heat transfer part that transfers heat of the heat exchanging medium to the adsorption medium. The heat transfer part is capable of holding the adsorption medium, an amount of which is capable of being adsorbed by the adsorbent of the adsorption part.

Abstract: An adsorber includes: a heat-medium pipe through which a heat medium flows; an adsorbent layer having an adsorbent that adsorbs a vapor-phase refrigerant located outside the heat-medium pipe by being cooled by the heat medium, and further desorbs the adsorbed refrigerant by being heated; and a heat-transfer member that transfers heat between the heat-medium pipe and the adsorbent. In the adsorber in which the heat-transfer member and the adsorbent are integrally formed, an adsorbent filling ratio ϕ is set at 70% or less when the adsorbent filling ratio ϕ is defined as a value obtained by dividing a filling density ρ of the adsorbent filled in the adsorbent layer by a true density ρabs of particles of the adsorbent. For example, the adsorber may be suitably used for an adsorption refrigerator.

Abstract: A thermoelectric power generator includes: a pipe in which a first fluid flows; a power generation module including a thermoelectric conversion element; and a holding member that is in contact with a one side part of the power generation module, such that heat of a second fluid that is higher in temperature than the first fluid transfers to the one side part of the power generation module. The holding member holds the power generation module and the pipe in a heat transferable state, such that the pipe is in contact with the other side part of the power generation module. The thermoelectric power generator includes a heat conductive component interposed between the holding member and the pipe to define a heat transfer course through which heat transfers from the second fluid to the first fluid, at downstream of the power generation module in a flowing direction of the second fluid.

Abstract: A thermoelectric generator includes a tube in which a first fluid flows, a power generation module, a holding member, and a heat exchanging fin. The power generation module includes a thermoelectric conversion element. The holding member holds a stacked body in which the power generation module and the tube are stacked with each other such that heat can be transferred between the power generation module and the tube. Both end portions of the holding member are located and fixed outside both ends of the stacked body. The heat exchanging fin includes a pair of end fin portions provided on the reverse surface of the holding member at portions corresponding to the both ends of the stacked body, and an intermediate fin located between the pair of end fin portions and higher in stiffness than the pair of end fin portions.
