Sealing and elastomer components for lithium battery systems
There are three different technologies for cooling batteries: air cooling, direct liquid cooling with water-Glycol® mixtures, and direct temperature control with air conditioning systems or with cooling systems based on refrigerants such as partly fluorinated hydrocarbons like …
A technology for sealing rings and batteries, which is applied to sealing materials, battery pack parts, battery boxes/covers, etc., can solve problems such as unopened, easy explosion of batteries, swelling of the connection part and contact with the bottom cover of the negative electrode, etc., to achieve Ensure unimpeded pressure relief, reduce the risk …
2. O-ring Sealing Principles O-rings are bi-directional seals, circular in shape and cross section. O-rings are generally made of an elastomeric material, but may be made of other materials such as PTFE or metal. This hand-book deals entirely with elastomeric O-rings and PTFE encapsu
Aeroelastic stability of labyrinth seal ring under steady and …
It is easy to cause circumferential intake distortion of aero-engine when the aircraft is in crosswind or flying with large angle of attack [26], and then cause circumferential intake distortion of the labyrinth seal ring, which means that the total pressure at the air inlet of the labyrinth seal ring is unevenly distributed along the circumferential direction.
Technical Handbook O-rings The sealing principle of the Quad-Ring®/X-Ring is nearly the same as the O-ring sealing. The initial sealing is achieved by the diametrical squeeze in ®a right angled groove. The system pres-sure itself creates a positive sealing force. Following are some®
Heat Sealing Technology and Engineering for Packaging: Principles and Applications …
For example, sealing quality is strongly dependent on the main process parameters; temperature, time and pressure. 5, 9 By using the correlations between these parameters and precise controlling ...
The working principle is as follows: when the seal ring for the alkaline battery of the automobile is used, the seal ring main body 1 is installed, if the leakage phenomenon occurs in the battery, the leakage can be collected into the acid body 51 by the liquid

6 · a mating ring that contains grooves machined near the outer diameter of the face of the ring (fig. 2-2). The grooves are machined only to the radial midpoint of the ring face, and the groove depth is only a few microns. The shape of the grooves in the mating ring (the groove pattern) is optimized to enhance seal performance (explained later in this chapter).
