Abstract:
1. A mechanical seal comprising a rotating ring and a mating ring adapted to seal to one another, wherein: (a) said mating ring comprises a first stationary ring comprising a circumferential groove-channel, a seal face, and an outer and inner surface each having a plurality of symmetrically-spaced radial holes adapted respectively to form inlet and outlet ports, and a second stationary ring comprising a circumferential diverter; (b) said circumferential groove-channel is adapted to receive said circumferential diverter so that, when combined, said first and said second stationary rings form said mating ring having a circumferential, divergent flow-channel communicating with said inlet and said outlet ports; and (c) if a coolant is supplied to said divergent flow-channel through said inlet ports, said divergent flow-channel causes the coolant to flow to substantially all portions of the interior surface area of said seal face before exiting through said outlet ports; whereby heat transfer at the interface of said rotating ring and said mating ring is substantially greater than what would be the heat transfer between otherwise identical sealing members lacking said divergent flow-channel.
