Abstract:
Disclosed is a battery module including a base plate on which unit modules, each with two or more secondary batteries therein, are stacked in a vertically erected state, a pair of end plates disposed in tight contact with outer surfaces of outermost unit modules while bottoms of the end plates are fixed to the base plate, and supporting bars connected between opposite sides of upper or side parts of the end plates so as to support the end plates, wherein each of the end plates includes a main body contacting a corresponding one of the unit modules, and a top wall, a bottom wall, and a pair of side walls protruding outward from the perimeter of the main body, the thickness of each of the side walls being increased from the top to the bottom wall, thereby dispersing pressure (bending load) from the unit modules and the supporting bars.
Abstract:
Disclosed herein is a middle- or large-sized battery pack case in which a battery module having a plurality of stacked battery cells, which can be charged and discharged, is mounted, wherein the battery pack case is provided with a coolant inlet port and a coolant outlet port, which are disposed such that a coolant for cooling the battery cells can flow from one side to the other side of the battery module in the direction perpendicular to the stacking direction of the battery cells, the battery pack case is further provided with a flow space (‘inlet duct’) extending from the coolant inlet port to the battery module and another flow space (‘outlet duct’) extending from the battery module to the coolant outlet port, and one or more guide members are disposed in the inlet duct for guiding the flow of the coolant in the direction parallel to the stacking direction of the battery cells.
Abstract:
Disclosed is a battery pack including a battery module array, wherein a reinforcement member is coupled to side walls of end plates or sides of main members at an outer side of an outermost battery module of the battery module array to minimize deformation of the battery pack when the battery pack is vibrated in the front and rear direction.
Abstract:
A fluid heating device capable of reducing the amount of the generated greenhouse gases while improving the yield of target compounds (ethylene, propylene and hydrogen, etc.) in a cracking process by controlling inflow heat fluxes themselves, respectively, in accordance with the progress degree of pyrolysis. The fluid heating device reduces a phenomenon that coke is generated by controlling inflow heat fluxes themselves, respectively, in accordance with the progress degree of pyrolysis in consideration of physical and/or chemical characteristics of various targets of pyrolysis, and reducing the amount of production of compounds (methane, ethane, benzene and fuel oil, etc.) other than the target compounds. A method of using the fluid heating device is also provided.
Abstract:
A device for detecting a solution state includes: a probe including a detecting portion having at least one open surface to measure the solution state; a mesh disposed on a path through which a solution is introduced to the detecting portion; and a support portion disposed on the outside of the probe, and having an opening surrounding the at least one open surface of the detecting portion. The opening defines the path through which the solution is introduced to the detecting portion, and the mesh is mounted in the opening of the support portion.
Abstract:
A distributing plate for a high-viscosity fluid which distributes and discharges the high-viscosity fluid is disclosed. The distributing plate may comprise: a flat top surface; a side surface having a diameter that increases downwardly from the upper surface; a plurality of inner holes arranged on the upper surface along a plurality of first imaginary concentric circles; and a plurality of outer holes arranged on the side surface along a plurality of second imaginary concentric circles. The ratio of the area of each inner hole to the area of each outer hole may be 1.2-1.4. In addition, an apparatus of distributing a high-viscosity fluid including the distributing plate for a high-viscosity fluid is disclosed.
Abstract:
The present invention relates to a method for preparing a carbon nanotube fiber which is a continuous array of carbon nanotube. The present invention enables minimization of rotational flow inside a tube reactor and thus can facilitate enhanced tensile strength of the prepared carbon nanotube fiber.
Abstract:
The present invention relates to a dispersion device and a defoamation device comprising the same, which provides a dispersion device comprising a dispersion plate equipped with an inclined surface extended downwards obliquely and raw material inflow nozzles formed on the inclined surface to introduce a raw material into the inclined surface; and a band spaced apart from the inclined surface of the dispersion plate to form a gap from the inclined surface, thereby being configured so that the raw material flows through the gap.
Abstract:
