摘要： A gas sensor includes a positive electrode of a carbon material and a negative electrode. The gas sensor further includes an insulation substrate, where the positive electrode and the negative electrode are attached to the insulation substrate, and surfaces of the positive electrode and the negative electrode and a surface of a portion of the insulation substrate between the positive electrode and the negative electrode are coated with a hygroscopic salt. The gas sensor may maintain moisture on the surface of the sensor electrode without using a separate external moisture supply device and may sense a gas with a high sensitivity even without using a high-priced catalyst metal or a high-temperature reaction.

摘要： A housing for a thermoelectric module can stably protect individual elements of the thermoelectric module such as thermoelectric elements, electrodes, and insulating boards, while maintaining power generation performance of the thermoelectric module. The housing for a thermoelectric module includes: a housing enveloping at least one thermoelectric module; and a heat barrier unit configured to prevent a flow of heat from being transferred through a sidewall of the housing.

摘要： A thermoelectric module includes: an electrode; a double layer stacked on a thermoelectric pellet; and a solder layer interposed between the double layer and the electrode to bond the double layer to the electrode, the solder layer containing a Sn—Cu-based alloy. The solder layer is formed to have an interface with one of the double layer and the electrode and has at least one ε layer having an ε phase (Cu3Sn).

摘要： An apparatus for manufacturing a thermoelectric module is provided. The thermoelectric module includes thermoelectric pellets, first electrodes, second electrodes, and an insulating substrate. The apparatus includes a fixing tray to which the thermoelectric module is fixed, a first die including a first heating member configured to heat a first adhesive layer, which is interposed between the thermoelectric pellets and the first electrodes. The fixing tray is mounted on the first die such that the insulating substrate faces the first heating member. A second die includes a second heating member configured to heat a second adhesive layer, which is interposed between the thermoelectric pellets and the second electrodes, the second die facing the second electrodes. A transfer unit is configured to transfer at least one of the first die and the second die to adjust a distance between the first die and the second die.

摘要： A device for indirectly cooling a battery module of an eco-friendly vehicle is provided that cools the battery module using an interfacial plate into which a heat pipe is inserted to maximize battery heat emission performance and simultaneously prevent degradation of battery performance. A thermally-conductive interfacial plate in which a heat pipe is embedded by over-molding is disposed between battery cells and a heat sink, which is a condensation unit, integrally connected to an upper end of the heat pipe is disposed in a cooling air flow path to improve contact strength between the interfacial plate and the battery cells. A planar heat emitter is disposed between the battery cells where the interfacial plate is not disposed to heat the battery to a proper-level temperature in a cold-start environment and a low-temperature environment, thereby improving battery performance and preventing degradation in vehicle power.
