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, and the battery pack case is further provided with beads formed in a concavo-convex shape for improving the structural stability of the battery pack case against an external force, the beads being constructed in an outwardly-protruding structure to allow the coolant to be uniformly introduced into the battery module from the coolant inlet port in the advancing direction of a fluid in a flow space ("inlet duct") defined between the coolant inlet port and the battery module.
Abstract:
A treater oven for drying a prepreg includes: a pipe conduit configured such that the prepreg is able to pass therethrough; a the first structure connected to one side of the pipe conduit and supplying heated air to the pipe conduit; and the second structure connected to the other side of the pipe conduit and discharging the heated air from the pipe conduit. The first structure includes: an air supply portion connected to a heat exchanger and supplying the heated air; an air distribution discharge portion discharging the heated air supplied from the air supply portion through a pair of discharging outlets in both sides of the prepreg; and at least one perforated plate symmetrically disposed in air passageways of the air distribution discharge portion.

Abstract:
The present invention relates to an agitating apparatus and to agitating hooks for same. The agitating apparatus of the present invention comprises: a rotary shaft rotatably arranged within a reactor; rotary blades arranged on the outer circumferential surface of the rotary shaft, such that the rotary blades rotate together with the rotary shaft in order to agitate materials in the reactor; and agitating hooks arranged on the inner wall of the reactor such that a pair of agitating hooks are spaced apart from each other, and the rotary blades pass through the gap between the agitating hooks. In addition, the width of the gap between the agitating hooks is formed such that an outlet for the exit of the rotary blade is wider than an inlet for the entry of the rotary blade. According to the above-described present invention, constant pressure is applied from the rotary blade inlet to the rotary blade outlet of the gap between the agitating hooks, thus minimizing the occurrence of torsional moment at the agitating hooks. Consequently, the durability of the agitating hooks is improved, and the reliability of products is increased.
Abstract:
Disclosed herein is a battery pack case in which a battery module (32) having a plurality of stacked unit cells (30) is mounted. The battery pack case is provided at an upper part and a lower part thereof with a coolant inlet port (10') and a coolant outlet port (20'), respectively. The coolant inlet port (10') and the coolant outlet port (20') are directed in opposite directions. The battery pack case is further provided with a coolant introduction part (40') and a coolant discharge part. An upper end inside part of the coolant introduction part (40') is configured in a structure in which an incline plane starting from an end opposite to the coolant inlet port (10') has an inclination increasing toward the coolant inlet port (10') with respect to the top of the cell stack.
